Description
本発明は、例えば差圧計や流量計などのフィールド機器の検出器と変換器の回転構造に関し、ねじ止めされた検出器と変換器の回転構造の改善に関する。 The present invention relates to a rotating structure of a detector and a converter of a field device such as a differential pressure gauge and a flow meter, and relates to an improvement of a rotating structure of a screwed detector and a converter.
現場に設置された差圧計や流量計などフィールド機器では配管の配置具合などにより変換器の目盛等が見にくくなったりすることがある。その場合、検出器に対して変換器を回転させる作業が発生する。 In field devices such as differential pressure gauges and flow meters installed at the site, the scale of the converter may become difficult to see depending on the arrangement of piping. In that case, the operation | work which rotates a converter with respect to a detector generate | occur | produces.
図３（ａ）はフィールド機器の検出器１と変換器２および接合部３の要部構成を示すものである。このような検出器１と変換器２では接合部３を摺動面として変換器２を矢印Ａ方向に回転させ、変換器の向きを調整している。検出器１と変換器２は数本のねじにより固定されている。 FIG. 3A shows the configuration of the main parts of the detector 1, the converter 2 and the joint 3 of the field device. In such a detector 1 and the converter 2, the direction of the converter is adjusted by rotating the converter 2 in the direction of arrow A with the joint 3 as a sliding surface. The detector 1 and the converter 2 are fixed by several screws.
図３（ｂ〜ｄ）は検出器１と変換器２を固定するための要部の一例を示すもので、図３（ｂ）は正面図、図３（ｃ）は図３（ｂ）のＡ−Ａ断面図、図３（ｄ）は図３（ｂ）のＡ−Ａ断面図斜視図である。 FIGS. 3B to 3D show an example of a main part for fixing the detector 1 and the converter 2, FIG. 3B is a front view, and FIG. 3C is a diagram of FIG. AA sectional view and Drawing 3 (d) are AA sectional view perspective views of Drawing 3 (b).
これらの図において、検出器１と変換器２の摺動面は円板状の鍔（１ａ，２ａ）を合わ
せた状態とされ、変換器２側の４箇所に形成されたねじ穴２ｂに検出器１側に形成された
通し孔１ｂを介してねじ４がねじ込まれて固定されている。
In these figures, the sliding surfaces of the detector 1 and the converter 2 are in a state in which disc-shaped ridges (1a, 2a) are combined, and are detected in screw holes 2b formed at four locations on the converter 2 side. A screw 4 is screwed and fixed through a through hole 1b formed on the container 1 side.
図３（ｅ〜ｇ）は検出器１と変換器２を固定するための他の従来例の要部の一例を示すもので、図３（ｅ）は正面図、図３（ｆ）は図３（ｅ）のＡ−Ａ断面図、図３（ｇ）は図３（ｅ）のＡ−Ａ断面図斜視図である。 FIGS. 3 (e to g) show an example of a main part of another conventional example for fixing the detector 1 and the converter 2, FIG. 3 (e) is a front view, and FIG. 3 (f) is a diagram. 3 (e) is an AA cross-sectional view, and FIG. 3 (g) is a perspective view of the AA cross-sectional view of FIG. 3 (e).
これらの図において、検出器１の鍔部１ａが変換器２に形成された穴２ｃに挿入され、検出器１の鍔１ａの側面に形成されたリング溝１ｃに変換器２の側面に形成されたねじ孔２ｄを介してねじ４がねじ込まれて固定されている。 In these drawings, the flange 1a of the detector 1 is inserted into the hole 2c formed in the transducer 2, and is formed on the side surface of the transducer 2 in the ring groove 1c formed on the side surface of the flange 1a of the detector 1. The screw 4 is screwed and fixed through the screw hole 2d.
ところで、上述の従来技術において、変換器２を所望の方向に回転させるには検出器１と変換器２を分離する必要があるが、設置後の回転は時間と工数を要するので、可能な限り設置状況に合わせて向きを調整しておく方が望ましい。 By the way, in the above-mentioned prior art, it is necessary to separate the detector 1 and the converter 2 in order to rotate the converter 2 in a desired direction. However, since rotation after installation requires time and man-hours, as much as possible. It is desirable to adjust the orientation according to the installation situation.
図では省略するが検出器１と変換器２の間にはこれらを電気的に接続するためのケーブルなども通っていて設置後の回転は非常に難しい。また、図（ｂ〜ｄ）に示す従来例では検出器１と変換器２のねじ４の数（図では４個）にもよるが、回転角度に制約があるという課題がある。 Although not shown in the drawing, a cable or the like for electrically connecting them passes between the detector 1 and the converter 2, and rotation after installation is very difficult. Further, in the conventional example shown in FIGS. 4B to 4D, there is a problem that the rotation angle is limited, although it depends on the number of screws 4 of the detector 1 and the converter 2 (four in the figure).
また、図（ｅ〜ｇ）に示す従来例では変換器２の外周に配置されたねじ４を緩めて回転させ再度締め付けを行う必要があるが、設置後は工具などの作業スペースの問題があり作業性がよいとは言えない。
また、この従来例では、ねじ４を検出器１に押し当てることにより固定しているため、固定後も回転方向に力を加えると変換器２が回転してしまうという課題がある。
Further, in the conventional example shown in FIGS. (Eg) to (g), it is necessary to loosen and rotate the screw 4 disposed on the outer periphery of the converter 2 and perform the tightening again, but there is a problem of work space such as tools after installation. It cannot be said that workability is good.
Further, in this conventional example, since the screw 4 is fixed by being pressed against the detector 1, there is a problem that the converter 2 rotates when a force is applied in the rotation direction after the fixing.
従って本発明は、検出器に対して容易に変換器を回転させることができる検出器と変換器の回転構造を提供することを目的としている。 Accordingly, an object of the present invention is to provide a detector and a rotating structure of the converter that can easily rotate the converter with respect to the detector.

図１は本発明の検出器と変換器の回転構造を示す要部正面図（ａ）、図（ａ）のＡ−Ａ断面図（ｂ）、図（ａ）のＡ−Ａ断面斜視図（ｃ）および分解斜視図（ｄ）である。
これらの図において、１１は大径部11ａと小径部11ｂからなる断面凸状に形成された検出器である。１２は中心部に検出器の小径部11ｂが挿入され、一端が検出器の大径部11ａに接触した状態で他端が小径部の端部より僅かに長く段差ｄを有する程度に形成された変換器である。
FIG. 1 is a front view of a main part showing a rotation structure of a detector and a converter according to the present invention (a), AA sectional view (b) of FIG. (A), and AA sectional perspective view of FIG. It is c) and an exploded perspective view (d).
In these drawings, reference numeral 11 denotes a detector formed in a convex section having a large diameter portion 11a and a small diameter portion 11b. 12 is formed in such a manner that the small diameter portion 11b of the detector is inserted in the center, and the other end is slightly longer than the end portion of the small diameter portion with one end in contact with the large diameter portion 11a of the detector. It is a converter.
変換器１２には他端側（小径部の端部側）から所定の深さｅに形成され前記検出器の小径部との間に円筒状の空間Ｐが形成されている。この空間Ｐには検出器の小径部11ｂを巻き回してコイルばね６が配置されている。５は円板状のばね押さえであり、段差ｄを埋める程度の厚さに形成されている。 The converter 12 is formed with a predetermined depth e from the other end side (end portion side of the small diameter portion), and a cylindrical space P is formed between the transducer 12 and the small diameter portion of the detector. In this space P, a coil spring 6 is arranged by winding the small diameter portion 11b of the detector. Reference numeral 5 denotes a disk-shaped spring presser, which is formed to have a thickness enough to fill the step d.
この円板状のばね押さえ５は複数（図では４本）のねじ４により検出器の小径部11ｂの端部にばね４を押圧した状態で固定され、同時に変換器１２をコイルばね６により検出器１１に押圧した状態となっている。７で示す部分は噛合い構造とされ、図では変換器１２の一端と検出器の大径部11ａが接触する部分が歯型状に形成されて噛合った状態とされている。 This disk-shaped spring retainer 5 is fixed in a state where the spring 4 is pressed against the end of the small diameter portion 11b of the detector by a plurality of (four in the figure) screws 4, and the transducer 12 is detected by the coil spring 6 at the same time. The container 11 is pressed. The portion indicated by 7 has a meshing structure, and in the figure, the portion where one end of the converter 12 and the large-diameter portion 11a of the detector are in contact is formed in a tooth shape and meshed.
上述の構成において、変換器１２を噛合い構造が外れる程度に持ち上げ検出器１１に対して変換器１２を回転させる。その場合噛合い構造の歯数を細かく形成しておけば、小刻みに回転位置を決めることができる。 In the above-described configuration, the converter 12 is lifted to the extent that the meshing structure is released, and the converter 12 is rotated with respect to the detector 11. In that case, if the number of teeth of the meshing structure is formed finely, the rotational position can be determined in small increments.
図２は他の実施例を示すもので、この例では噛合い構造７ａを波（山）型にしたものでり、他の部分は図１と同様なのでここでの説明は省略する。
このような構成においても、噛合いが外れる程度に変換器を持ち上げるだけで検出器に対して容易に変換器を回転させることができる
FIG. 2 shows another embodiment. In this example, the meshing structure 7a has a wave (mountain) shape, and the other parts are the same as those in FIG.
Even in such a configuration, the transducer can be easily rotated with respect to the detector simply by lifting the transducer to such an extent that the engagement is disengaged.
なお、以上の説明は、本発明の説明および例示を目的として特定の好適な実施例を示したに過ぎない。実施例ではばね押圧部材のねじを４本としたが、１本以上であれば２本、３本でも４本以上でも良く、ねじに限らず接着、リベットのようなものでも良い。 The above description merely shows a specific preferred embodiment for the purpose of explanation and illustration of the present invention. In the embodiment, the spring pressing member has four screws. However, if it is one or more, it may be two, three, or four or more.
また、ばね押圧部材は実施例では段差ｄに収めるために円板状としたが、変換器の一端が検出器の大径部に接触した状態で他端が小径部の端部と略面一になる程度に形成しておけば、矩形の中心付近に穴を開けたようなものであってもよく、コイルばねを押圧可能であれば変換器の他端から突き出た状態であってもよい。 Further, in the embodiment, the spring pressing member has a disc shape so as to be accommodated in the step d, but the other end is substantially flush with the end of the small diameter portion while one end of the transducer is in contact with the large diameter portion of the detector. If it is formed to the extent that it becomes, it may be like a hole in the vicinity of the center of the rectangle, or it may be in a state protruding from the other end of the converter as long as the coil spring can be pressed. .
即ち本発明では、略面一とは変換器の一端が検出器の大径部に接触した状態で他端が小径部の端部よりコイルばねを押圧可能な状態で多少突き出ていても、本実施例に示したように多少凹んだ状態でもよい状態と定義している。
要はコイルばねで変換器の一端を検出器の大径部に押さえつけ、変換器をコイルばねの力に抗して持ち上げたときに噛合いが外れるような構成であれば良い。
That is, in the present invention, even if the one end of the transducer is in contact with the large diameter portion of the detector and the other end protrudes somewhat from the end of the small diameter portion in a state where the coil spring can be pressed, As shown in the embodiment, it is defined as a state that may be slightly depressed.
In short, any configuration may be used as long as one end of the transducer is pressed against the large-diameter portion of the detector by a coil spring and the meshing is released when the transducer is lifted against the force of the coil spring.
また、検出器と変換器の形状は要部のみを示したが、図示の例に限ることなく任意に設計可能である。
従って本発明は、上記実施例に限定されることなく、その本質から逸脱しない範囲で更に多くの変更、変形を含むものである。
Moreover, although the shape of the detector and the converter has shown only the principal part, it can design arbitrarily, without restricting to the example of illustration.
Therefore, the present invention is not limited to the above-described embodiments, and includes many changes and modifications without departing from the essence thereof.
