Description
本発明は、ガス栓のロック構造、特に、ガス栓を閉状態でロックするガス栓のロック構造に関する。 The present invention relates to a gas plug lock structure, particularly a gas plug lock structure that locks the gas plug in a closed state.
一般にガス栓は、ガス流路に連通するせん収容部とその上方に連続する筒状部とからなるガス栓本体と、前記せん収容部内に回動自在に収容されて前記ガス流路を連通又は閉塞させるせんと、前記筒状部に回動自在に嵌合して前記せんを回動操作する操作つまみとからなり、特に、屋外に設置されるガスメータ用のガス栓では、不使用時に、せん収容部内で閉状態に位置しているせんが、いたずら等によって、不用意に開状態とならないように、ガス栓の閉状態にて、操作つまみを回動阻止状態にロックさせるロック機構部が設けられている。 Generally, a gas plug is rotatably housed in a gas plug main body including a spiral housing portion communicating with the gas flow path and a tubular portion continuous above the gas flow path, and communicates with or communicates with the gas flow path. It consists of a pin to be closed and an operation knob that rotatably fits into the tubular portion to rotate the pin. In particular, a gas plug for a gas meter installed outdoors has a pin when not in use. Although it is located in the closed state in the accommodating part, a lock mechanism part is provided to lock the operation knob to the rotation blocking state while the gas plug is closed so that it will not be inadvertently opened due to mischief or the like. Has been done.
ロック機構部としては、ガス流路が閉塞される方向にせんを回動させた状態（ガス栓の閉状態）にて、操作つまみを回動阻止状態にロックするロックネジと、ロックネジが螺合された状態で収容されるロックネジ収容ネジ孔と、前記ロックネジ収容ネジ孔から進出させたロックネジの一部が係合する係合孔とからなるものが知られている。
例えば、特許文献１のガス栓では、ガス栓本体の筒状部の外周面よりも外側に位置する操作つまみの下面の所定個所に、前記ロックネジ収容ネジ孔が下方に開放するように設けられ、前記ガス栓の閉状態にて、前記ロックネジ収容ネジ孔の下方に、前記係合孔が配設されるように、前記係合孔が上下に貫通する凸部をガス栓本体の筒状部の外周面から突設させている。
上記従来のロック機構部で、ガス栓の閉状態における操作つまみを回動阻止状態にロックさせるには、前記ロックネジ収容ネジ孔に対向している係合孔の下方開放端から特殊工具を差し入れて、前記ロックネジ収容ネジ孔に螺合させているロックネジを緩めて、ロックネジの一部を、前記ロックネジ収容ネジ孔から係合孔内へ進出させる。この状態で、操作つまみを回動させようとしても、操作つまみの下面から突出するロックネジが、ガス栓本体の筒状部に突設させた凸部の係合孔に係合することとなるため、操作つまみの回動は阻止される。これにより、ガス栓は閉状態に保持される。
As the lock mechanism, the lock screw that locks the operation knob to the rotation blocking state and the lock screw are screwed together in a state where the wire is rotated in the direction in which the gas flow path is closed (the gas plug is closed). It is known that the lock screw accommodating screw hole accommodated in the state of being accommodated and an engaging hole in which a part of the lock screw advanced from the lock screw accommodating screw hole engages.
For example, in the gas plug of Patent Document 1, the lock screw accommodating screw hole is provided at a predetermined position on the lower surface of the operation knob located outside the outer peripheral surface of the tubular portion of the gas plug body so as to open downward. In the closed state of the gas plug, the convex portion through which the engaging hole penetrates up and down is formed in the tubular portion of the gas plug body so that the engaging hole is arranged below the lock screw accommodating screw hole. It is projected from the outer peripheral surface.
In the conventional lock mechanism unit, in order to lock the operation knob in the closed state of the gas plug to the rotation blocking state, a special tool is inserted from the lower open end of the engaging hole facing the lock screw accommodating screw hole. , Loosen the lock screw screwed into the lock screw accommodating screw hole, and allow a part of the lock screw to advance into the engaging hole from the lock screw accommodating screw hole. Even if an attempt is made to rotate the operation knob in this state, the lock screw protruding from the lower surface of the operation knob will engage with the engaging hole of the convex portion protruding from the tubular portion of the gas plug body. , The rotation of the operation knob is blocked. As a result, the gas plug is kept in the closed state.
なお、上記従来のロック機構部を構成している前記係合孔の下方開放端近傍域には、ロックネジの径よりも小さな小径穴を設けたり、前記係合孔に直交するように凸部に設けた封印穴に針金等を挿通させたりすることにより、ロック状態にあるロックネジは係合孔を介して下方へ落下せず、抜け止め状態に保持されている。また、ロックネジは特殊工具でないと、締め付けたり緩めたりできないから、いたずらで上記ロックネジを締め付けてロック状態を解除することはできない。 In the region near the lower open end of the engagement hole constituting the conventional lock mechanism portion, a small diameter hole smaller than the diameter of the lock screw may be provided, or a convex portion may be provided so as to be orthogonal to the engagement hole. By inserting a wire or the like into the provided sealing hole, the locked screw in the locked state does not fall downward through the engaging hole and is held in the retaining state. Further, since the lock screw cannot be tightened or loosened unless it is a special tool, the lock screw cannot be unnecessarily tightened to release the locked state.
しかしながら、上記従来技術のものでは、ロックネジを締め付けてロックネジの略全体をロックネジ収容ネジ孔内に収容することで、上記ロック状態を解除して、操作つまみを、ガス栓の開方向へ回動させると、操作つまみのロックネジ収容ネジ孔の下方には、上記した凸部に相当するような突出部分は存在しないから、ロックネジのロックネジ収容ネジ孔への螺合度合いが緩むと、ロックネジがロックネジ収容ネジ孔から脱落してしまう不都合がある。 However, in the above-mentioned conventional technique, by tightening the lock screw and accommodating substantially the entire lock screw in the lock screw accommodating screw hole, the locked state is released and the operation knob is rotated in the opening direction of the gas plug. Since there is no protruding portion corresponding to the above-mentioned convex portion below the lock screw accommodating screw hole of the operation knob, when the degree of screwing of the lock screw into the lock screw accommodating screw hole is loosened, the lock screw becomes the lock screw accommodating screw. There is an inconvenience of falling out of the hole.
本発明は、かかる点に鑑みてなされたものであり、『ガス流路を開閉するせんが収容されているせん収容部の開放端側に、筒状部が連設された構成のガス栓本体と、

The present invention has been made in view of this point. When,
It is a lock structure of a gas plug including an operation knob that is fitted to the tubular portion so as to be relatively rotatable and operates the spiral.
In the gas plug lock structure provided with a lock mechanism having a lock screw that locks the operation knob to the rotation blocking state in the closed state of the gas plug in which the gas flow path is blocked by the pipe.
An object of the present invention is to prevent the inconvenience that the lock screw falls off from the lock mechanism portion in the open state of the gas plug in which the gas flow path is opened by rotating the operation knob.

前記操作孔は、前記操作つまみの頂面に開放するように形成されている』ことである。
The technical means for solving the above-mentioned problems is as follows: "The lock mechanism portion is provided outside the fitting portion between the operation knob and the tubular portion of the gas plug main body.
And it provided in front Symbol cylindrical portion, locking screw in the direction of the rotation axis of the operation knob and screwable locking screw accommodating threaded hole,
The operation knob mini provided and a portion of the lock screw which is advanced from the lock screw receiving threaded hole in the closed state of the gas valve consists engageable engagement recess,
Before the back side of the Kigakarigo recess, it said and said locking screw screwing operable operation hole smaller in diameter than the engaging recess is formed continuously,
At the open state of the gas valve that is opened to the gas flow path Nde allowed the flange portion is provided, et al is having a screw receiving surface for holding the state retaining the locking screw is screwed accommodated in the lock screw housing screw holes,
The collar portion is projected in an annular shape along the outer peripheral surface of the operation knob.

上記技術的手段は次のように作用する。
ロック機構部は、操作つまみの回動軸の方向に沿ったロックネジ収容ネジ孔と係合凹部と、両者に螺合又は係合可能なロックネジとからなり、操作つまみとガス栓本体の筒状部との嵌合部の外側に位置するように設けられている。ガス栓の閉状態にて、ロックネジ収容ネジ孔は係合凹部に対向し、ロックネジ収容ネジ孔に螺合されているロックネジのロックネジ収容ネジ孔からの進出部分を係合凹部に係合させれば、操作つまみの回動はロックネジによって阻止され、ガス栓は閉状態にロックされた状態に保持される。
そして、前記係合凹部に連続するように形成されている操作孔に、例えば、前記ロックネジを螺合操作可能な工具を差し入れて、ロックネジがロックネジ収容ネジ孔に収容される方向へ螺合操作することにより、係合凹部からロックネジを退出させる。これにより、ロックネジの係合凹部への係合が外れるから、操作つまみのロック状態は解除され、操作つまみは、開方向へ回動自在となって、ガス栓を開状態とすることが出来る。
ガス栓の開状態において、ロックネジ収容ネジ孔に螺合収容されているロックネジは、鍔部のネジ受け面で抜け止め状態に保持される態様となるから、ロックネジの螺合度合いが緩んできても、ロックネジがロックネジ収容ネジ孔から脱落してしまう不都合はない。
なお、ロックネジ収容ネジ孔はガス栓本体の筒状部に、鍔部と係合凹部は操作つまみに設けられており、ロックネジをガス栓本体側のロックネジ収容ネジ孔内にほぼ全体が収容されるように螺合させた状態で、ガス栓を組み立てる。この状態においては、操作つまみは筒状部に対して回動自在であり、ロックネジ収容ネジ孔に螺合収容されているロックネジの進出方向には、操作つまみの外周面に突設させた鍔部が張り出している。これにより、ロックネジは、鍔部のネジ受け面によって、ロックネジ収容ネジ孔に抜け止め状態に保持される。
操作つまみの頂面に開放する操作孔から工具を挿入させて、ロックネジを緩める方向に螺合操作すれば、ロックネジはロックネジ収容ネジ孔から進出して係合凹部に係合し、操作つまみを回動阻止状態にロックすることが出来る。
操作つまみのロック状態を解除するには、再度操作孔から工具を差し入れて、ロックネジを締め付け方向に螺合操作すれば、ロックネジは係合凹部からロックネジ収容ネジ孔内へ退出し、ロックネジと係合凹部との係合は解除される。
上記課題を解決するための他の技術的手段は、『ガス流路を開閉するせんが収容されているせん収容部の開放端側に、筒状部が連設された構成のガス栓本体と、

前記操作孔は、前記筒状部の他の端面に開放するように形成されている』ことである。
このものでは、ガス栓本体の筒状部に設けたロックネジ収容ネジ孔の開放端面の反対側の端面に開放している操作孔に工具を挿入し、ロックネジを締め付ける方向に螺合操作すれば、ロックネジはロックネジ収容ネジ孔から進出して係合凹部に係合し、操作つまみを回動阻止状態にロックすることが出来る。
操作つまみのロック状態を解除するには、再度操作孔から工具を差し入れて、ロックネジを緩める方向に螺合操作すれば、ロックネジは係合凹部からロックネジ収容ネジ孔内へ退出し、ロックネジと係合凹部との係合を解除することが出来る。

Since the lock screw accommodating screw hole and the engaging recess that constitute the lock mechanism portion are provided on the outside of the fitting portion between the operation knob and the tubular portion of the gas plug body, the lock screw that is screwed into these is provided. Does not penetrate the gas plug body inside and outside, so that water droplets such as rainwater and dust do not enter the gas plug body via the lock mechanism.
Further, since the gas plug is assembled in a state where almost the entire lock screw is screwed and accommodated in the lock screw accommodating screw hole, and the lock screw cannot be removed in the assembled state, the lock screw retaining member is unnecessary.
また、ガス栓の開状態にて、ロックネジ収容ネジ孔に螺合収容されているロックネジの螺合状態が緩んできても、ロックネジの進出を阻止する位置に、鍔部が突設されているから、ロックネジが不用意にロックネジ収容ネジ孔から脱落することはなく、ロックネジを紛失してしまう不都合はない。
また、ガス栓の閉状態にて、ロックネジによる操作つまみのロック状態を解除するためには操作孔から差し込んでロックネジを締め付け又は緩めることができる工具が必要であり、前記操作孔も小径に設けられているから、専門業者以外の者は、ロックネジをロックしたりロック解除したりすることは出来ない。よって、操作つまみが、いたずら等により、不用意にロックされたりロック状態が解除されたるする不都合はない。
In addition, even if the lock screw screwed in the lock screw accommodating screw hole is loosened when the gas plug is open, the collar is projected at a position to prevent the lock screw from advancing. , The lock screw does not accidentally fall out of the lock screw accommodating screw hole, and there is no inconvenience of losing the lock screw.
Further, in order to release the locked state of the operation knob by the lock screw when the gas plug is closed, a tool that can be inserted from the operation hole to tighten or loosen the lock screw is required, and the operation hole is also provided with a small diameter. Therefore, no one other than a specialist can lock or unlock the lock screw. Therefore, there is no inconvenience that the operation knob is inadvertently locked or the locked state is released due to mischief or the like.
また、操作孔を係合凹部の奥に連続して設ける構成としたものでは、ガス栓を閉状態として、ロックネジ収容ネジ孔と係合凹部とを対応させないと、操作孔からロックネジを螺合操作できないから、ロック操作を間違うことがなく、安全性の高いガス栓となる。
また、操作孔が操作つまみの頂面に開放する構造としたものでは、操作つまみが壁面に沿って位置するようにガス栓が取り付けられている場合に、ロックネジの操作を容易に行うことが出来る。
Further, in the case where the operation hole is continuously provided in the back of the engagement recess, the lock screw is screwed from the operation hole unless the gas plug is closed and the lock screw accommodating screw hole and the engagement recess do not correspond to each other. Since it cannot be done, the lock operation is not mistaken and the gas plug is highly safe.
Further, in the structure in which the operation hole is opened to the top surface of the operation knob, the lock screw can be easily operated when the gas plug is attached so that the operation knob is located along the wall surface. ..

11 to 14 are explanatory views of the lock structure of the gas plug of the third embodiment, and the lock screw (100) constituting the lock mechanism portion (100) constituting the lock structure is shown. The lock screw accommodating screw hole (10) for screwing and accommodating 1) is provided in the tubular portion (32) of the gas plug body (30) so as to open upward, and the flange portion (12) and the engaging recess (11). Further, the operation hole (13) is provided in the operation knob (2).
As shown in FIGS. 12 and 14, the lower surface (25a) of one end of the knob portion (25) provided on the top surface of the operation knob (2) in the radial direction is attached to the screw receiving surface (25a) of the flange portion (12). An engaging recess (11) is formed so as to project outward so as to be flush with 12a) and open to the lower surface (25a) thereof. Then, in the closed state of the gas plug, a raised portion (35) is projected from the outer peripheral surface of the tubular portion (32) of the gas plug main body (30) at a position where the engaging recess (11) faces. A lock screw accommodating screw hole (10) that opens upward is formed in the raised portion (35).
このものでは、操作つまみ(2)のつまみ部(25)の頂面に開放させた操作孔(13)から工具を差し入れて、ロックネジ(1)を螺合操作するものであり、図１１及び図１２に示すように、ロックネジ収容ネジ孔(10)内にロックネジ(1)のほぼ全体が螺合収容されているガス栓の開状態から、操作つまみ(2)を９０度回動させて、図１３及び図１４に示すように、操作孔(13)及びその下方に連続する係合凹部(11)が形成されているつまみ部(25)の一端を、 ガス栓本体(30)の筒状部(32)に設けた(35)に合わせて、操作孔(13)から差し込んだ工具で、ロックネジ(1)を緩める方向に螺合させれば、ロックネジ(1)はロックネジ収容ネジ孔(10)から操作つまみ(2)のつまみ部(25)の下面(25a)に開放している係合凹部(11)内に進出し、操作つまみ(2)を回動阻止状態にロックすることが出来る。
尚、操作孔(13)は係合凹部(11)よりも小径に形成されているから、ロックネジ(1)を進出させ過ぎることはない。

この状態から、前記工具によって、ロックネジ(1)を締め付け方向に螺合させれば、ロックネジ(1)は、図１１に示すように、ロックネジ収容ネジ孔(10)内にほぼ全体が螺合収容されることとなり、ロックネジ(1)と係合凹部(11)との係合状態が解除されることから、操作つまみ(2)は回動自在となる。このとき、ロックネジ収容ネジ孔(10)の上方には、つまみ部(25)の下面(25a)に続く鍔部(12)のネジ受け面(12a)が位置することから、ロックネジ収容ネジ孔(10)内のロックネジ(1)は抜け止め状態に保持されることとなる。 From this state, if the lock screw (1) is screwed in the tightening direction with the tool, the lock screw (1) is screwed and accommodated almost entirely in the lock screw accommodating screw hole (10) as shown in FIG. Since the engagement state between the lock screw (1) and the engaging recess (11) is released, the operation knob (2) becomes rotatable. At this time, since the screw receiving surface (12a) of the flange portion (12) following the lower surface (25a) of the knob portion (25) is located above the lock screw accommodating screw hole (10), the lock screw accommodating screw hole ( The lock screw (1) in 10) will be held in a retaining state.
図１５及び図１６は、第４番目の実施の形態のガス栓のロック構造の説明図であり、このロック機構部(100)も、上記した第３番目の実施の形態と同様、ロックネジ(1)を螺合収容させるロックネジ収容ネジ孔(10)をガス栓本体(30)の筒状部(32)に設けた隆起部(35)に、係合凹部(11)及び鍔部(12)を操作つまみ(2)に設ける構成であるが、ロックネジ(1)の螺合度合いを調節する工具を差し込む操作孔(13)は、ロックネジ収容ネジ孔(10)の下方に連続する様に、隆起部(35)に、下方開放状態に設けている。
このものでは、ロックネジ(1)の螺合操作は、ガス栓本体(30)側の隆起部(35)の下方から工具を操作孔(13)内に差し入れて行われ、工具でロックネジ(1)を緩める方向に螺合させると、ロックネジ(1)は、図１５に示すように、ロックネジ収容ネジ孔(10)内へ収容され、操作つまみ(2)は回動自在となる。このとき、ロックネジ(1)の上方には、鍔部(12)のネジ受け面(12a)が位置することとなって、ロックネジ(1)の上方への抜け止めは防止される。
15 and 16 are explanatory views of the lock structure of the gas plug of the fourth embodiment, and the lock mechanism portion (100) is also a lock screw (1) as in the third embodiment described above. The engaging recess (11) and the flange (12) are provided in the raised portion (35) provided in the tubular portion (32) of the gas plug main body (30) with the lock screw accommodating screw hole (10) for screwing and accommodating). Although it is configured to be provided on the operation knob (2), the operation hole (13) into which the tool for adjusting the degree of screwing of the lock screw (1) is inserted is a raised portion so as to be continuous below the lock screw accommodating screw hole (10). (35) is provided in a downward open state.
In this case, the screwing operation of the lock screw (1) is performed by inserting the tool into the operation hole (13) from below the raised portion (35) on the gas plug body (30) side, and the lock screw (1) is screwed with the tool. When screwed in the loosening direction, the lock screw (1) is accommodated in the lock screw accommodating screw hole (10) as shown in FIG. 15, and the operation knob (2) becomes rotatable. At this time, the screw receiving surface (12a) of the flange portion (12) is located above the lock screw (1), and the lock screw (1) is prevented from coming off upward.
ガス栓を閉状態とすると、ロックネジ収容ネジ孔(10)の上方に係合凹部(11)が位置し、ロックネジ(1)を締め付け方向に螺合させると、ロックネジ(1)はロックネジ収容ネジ孔(10)から上方へ突出させられて、係合凹部(11)に係合する。これにより、操作つまみ(2)は回動阻止状態に保持される。 When the gas plug is closed, the engaging recess (11) is located above the lock screw accommodating screw hole (10), and when the lock screw (1) is screwed in the tightening direction, the lock screw (1) becomes the lock screw accommodating screw hole. It is projected upward from (10) and engages with the engaging recess (11). As a result, the operation knob (2) is held in the rotation blocking state.
なお、第３番目の実施の形態のガス栓のロック構造も、操作孔(13)は、操作つまみ(2)のつまみ部(25)の頂面に開放する構成としているため、第１番目の実施の形態で採用した、図７に示す、キャップ体(20)の凸部(23)で操作孔(13)を閉塞しておけばよい。 In addition, also in the lock structure of the gas plug of the third embodiment, since the operation hole (13) is configured to be open to the top surface of the knob portion (25) of the operation knob (2), the first one. The operation hole (13) may be closed by the convex portion (23) of the cap body (20) shown in FIG. 7, which is adopted in the embodiment.
第１番目と第３番目の実施の形態のガス栓のロック構造のように、操作孔(13)を操作つまみ(2)の上方に開放する構成のものでは、例えば、操作つまみ(2)が壁面やガスメータに沿うようにガス栓を横向きに設置される取付構造でも、操作孔(13)から工具を差し込んで、ロックネジ(1)の螺合操作がやり易い。
また、第２番目と第３番目の実施の形態のガス栓のロック構造のように、操作孔(13)を係合凹部(11)の奥に連続して設ける構成としたものでは、ロックネジ収容ネジ孔(10)と係合凹部(11)とが対応するように、ガス栓を閉状態としないと、操作孔(13)からロックネジ(1)の螺合操作はできないから、ロック操作を間違って行うことはなく、安全性の高いガス栓となる。
さらに、ガス栓の開状態において、ロックネジ(1)は鍔部(12)のネジ受け面(12a)で脱落防止状態に保持されるから、ロックネジ(1)の抜け止めのための他の部材を別途設ける必要もない。
In a configuration in which the operation hole (13) is opened above the operation knob (2) as in the lock structure of the gas plug of the first and third embodiments, for example, the operation knob (2) is used. Even with a mounting structure in which the gas plug is installed sideways along the wall surface or gas meter, it is easy to insert the tool through the operation hole (13) and screw the lock screw (1).
Further, in a configuration in which the operation hole (13) is continuously provided in the back of the engaging recess (11) as in the lock structure of the gas plug of the second and third embodiments, the lock screw is accommodated. The lock operation is incorrect because the lock screw (1) cannot be screwed from the operation hole (13) unless the gas plug is closed so that the screw hole (10) and the engagement recess (11) correspond to each other. It will be a highly safe gas plug.
Further, when the gas plug is open, the lock screw (1) is held in a fall-prevention state by the screw receiving surface (12a) of the flange portion (12), so that another member for preventing the lock screw (1) from coming off can be used. There is no need to install it separately.
