Description

  The present invention relates to a steadying metal fitting for a water control valve opening / closing shaft for operating opening / closing of a water control valve installed inside a housing buried in the ground.

Conventionally, as a steadying metal fitting for a water control valve opening / closing shaft for operating opening / closing of a water control valve installed inside a housing buried in the ground, for example, Japanese Patent Application Laid-Open No. 2001-65004 is known. .
JP 2001-65004 A

  However, the above-described conventional technique is based on a substantially arc-shaped bowl-shaped body in which the steady rest attached to the water control valve opening / closing shaft is divided into two so as to be fitted from the side of the water control valve opening / closing shaft. The steady rest base member (stopper) and the steady rest plate member placed on the steady rest base member (stopper), the whole steady rest body is a thin plate, In addition to the lack of stability, the structure is complicated, the cost is high, and the mounting and dismounting operations are troublesome.

  The steady rest of the present invention aims at solving the above-mentioned problem, and the steady rest of the water control valve opening / closing shaft for operating the opening / closing of the water control valve installed inside the housing buried in the ground. A ring body that is loosely fitted to the water control valve opening / closing shaft and that can be placed on a stopper provided on the water control valve opening / closing shaft, and an outer surface of the ring body, It is characterized by comprising an upper steady frame extending radially toward the inner wall surface and having a required gap formed between the inner wall surface of the housing and a required height. To do.

  Further, the steady rest of the present invention comprises a lower steady rest frame that is formed at a lower portion of the upper steady rest frame with a required gap between the inner wall surface of the housing and a required length. It is characterized by being provided integrally.

  Furthermore, the steady rest of the present invention is characterized in that a notch for avoiding an obstacle is provided between the connecting flanges provided at the upper end of the upper steady rest frame and the lower end of the lower steady rest frame. To do.

  The steady rest according to the present invention is a steady rest of a water control valve opening / closing shaft for operating opening / closing of a water control valve installed inside a housing embedded in the ground, and the water control valve opening / closing A ring body that is loosely fitted to the shaft and that can be placed on a stopper provided on the control valve opening and closing shaft, and extends radially from the outer surface of the ring body toward the inner wall surface of the housing And an upper anti-rest frame body formed with a required gap between the inner wall surface of the housing and a required height rising upward. Since the lower stabilization frame body is provided integrally with the inner wall surface of the body and provided with a required gap and is formed to hang downward for the required length, the inner wall surface of the housing is centered on the ring body. A frame body that is installed upward or downward along the shaft makes the runout of the control valve opening and closing shaft more stable and extremely effective. The upper and lower portions are provided with notch portions for avoiding obstacles between the connecting collars provided at the upper end and the lower end of the lower steady frame body. It is possible to easily insert and remove the steady rest from the housing using the obstacle avoidance notch provided on the bottom connecting collar on the top of the steady rest frame. The structure is simple, and the attachment / detachment operation to / from the control valve opening / closing shaft is simple, and the cost is low.

  The present invention relates to a ring body that is loosely fitted to a water control valve opening / closing shaft and that can be placed on a stopper provided on the water control valve opening / closing shaft, and is embedded in the ground from the outer surface of the ring body. An upper anti-rest frame extending radially toward the inner wall surface of the housing, and having a required gap between the inner wall surface of the housing and a desired height. It is possible to more stably and extremely effectively prevent the swing of the water control valve opening / closing shaft for operating the opening / closing of the water control valve installed inside the housing buried in the ground. Provide steady rest.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a steady rest according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a front view of Embodiment 1 of a steady rest metal object according to the present invention when only an upper steady rest frame is formed. FIG. 2 is a top view of the same.

  The steady rest 1 according to the present invention shown in FIG. 1 and FIG. 2 according to the present invention is loosely fitted on the water control valve opening / closing shaft 2 shown in FIG. 5 and on the stopper 4 provided on the water control valve opening / closing shaft 2. A ring body 5 that can be placed on the ring body 5, radially extending from the outer surface 5 a of the ring body 5 toward the inner wall surface 3 a of the housing 3 (extension portion 6), and the housing 3. The upper anti-stabilization frame body 7 is formed by providing a required gap with the inner wall surface 3a and raising the required height upward.

  FIG. 3 is a front view of a second embodiment of the steady rest according to the present invention when the upper and lower steady rest frames are formed. FIG. 4 is a perspective view of the same. FIG. 5 is an explanatory view showing a use state of the steady rest according to the present invention.

  5 shown in FIG. 5 is a water control valve opening / closing shaft for operating opening and closing of the water control valve installed inside the housing 3 embedded in the ground. Reference numeral 4 denotes a plurality of rod-shaped stoppers provided radially on the water control valve opening / closing shaft 2. The steady rest 1 of the present invention shown in the second embodiment has a required gap depending on the lower part of the upper steady rest frame 7 with a required gap between the inner wall surface 3a of the housing 3 and a lower part. The lower stabilization frame body 8 is integrally provided.

Moreover, the upper bracing frame 7 and a lower deflection engaging frame member 8, the with the ring body 5 and the extending portion 6, is integrally formed by including the required materials such as anti-corrosion touch of stainless steel or hard plastic Yes.

Further, the upper end of the upper steady frame 7 and the lower end of the lower steady frame 8 in the steady rest 1 of the present invention according to the second embodiment are integrally formed by a connecting collar 9 as shown in FIGS. However, if the upper and lower steady rest frames 7 and 8 themselves are strong, they are not necessarily required.
Reference numeral 10 denotes a notch for avoiding an obstacle provided in the connecting collar 9.
Reference numeral 11 denotes an obstacle protruding into the housing 3.

  Accordingly, when the water control valve opening / closing shaft 2 is operated using the obstacle avoiding notch 10, even if there is an obstacle in the housing 3, the operation can be easily performed. The stopper can be easily inserted and removed.

  The steady rest 1 according to the present invention provided with the upper steady rest frame body 7 and the lower steady rest frame body 8 is placed on the stopper 4 of the water control valve opening / closing shaft 2, and the water control valve opening / closing shaft is provided. When the opening and closing of the water control valve installed inside the housing 3 embedded in the ground by 2 is operated, the upper steady frame 7 and the lower steady frame 8 are provided on the inner wall surface of the housing 3. The vibration of the water control valve opening / closing shaft 2 in contact with 3a can be more stably and extremely effectively prevented, and the operation becomes simple.

It is a front view of Example 1 of the steady rest metal object concerning the present invention at the time of forming only an upper steady rest frame. It is the same top view. It is a front view of Example 2 of the steady rest metal object which concerns on this invention at the time of forming an upper and a lower steady rest frame. It is the same perspective view. It is explanatory drawing which shows the use condition of the steady rest according to this invention.
