Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a reflector provided on the top of a connecting rod that extends above a water control valve of a water pipe.

[Conventional technology]

The water control valve of the water pipe is buried in a box dug in the ground.
However, over the years, sediment has accumulated on it, making it invisible, so to prevent this, a stick is proposed (Japanese Utility Model Application No. 61-164737).

By the way, when operating this water control valve, there are many nights, so the position of this step bar may not be clearly known even if it extends from the bottom. Therefore, there is one in which a reflector like a large number of beads is mounted on the top surface of the stepping rod, and if there is a little light, this reflector shines and notifies its position.

[Problems to be solved by the device]

On the other hand, when operating the water control valve, a box-shaped handle is inserted at the top of this step rod. Even though it is said that the reflector is present and it is shining, its luminous intensity is small. Therefore, when the handle is inserted, it may hit this reflector, which may be damaged and cracked. In order to prevent this, there are some cases where the upper surface of the reflector is set lower than the top surface of the connecting rod, but this makes a dent in the upper surface of the reflector, and this time earth and sand accumulate and dust adheres here. It does not shine because it does. The earth and sand that had accumulated here was hard and sticky, and it was difficult to remove.

[Means for Solving the Problems]

Therefore, this invention proposes a reflector embedded in the top surface of a connecting rod that is added to the upper part of the water control valve so that the upper surface of the reflecting plate is located higher than the top surface of the connecting rod. While embedding the reflector, when the handle fitted to the upper part of the joint bar hits the reflector between the bottom of the embedding hole and the reflector, the upper face of the reflector is the joint bar. The problem described above is solved by interposing an elastic body having elasticity enough to retract from the top surface.

[Action]

By taking the above means, even if the handle hits the reflecting plate, the bottom of the reflecting plate is provided with an elastic body having elasticity enough to retract the upper surface of the reflecting plate from the top surface of the joint bar. Since it is interposed (the handle does not damage the reflector in this state), it is possible to prevent the reflector from being damaged.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

3 and 4 are cross-sectional views showing the relationship between the water control valve and the connecting rod, the water control valve 2 provided in the middle of the water pipe 1 is dug into the box 3 in the ground to Accommodate. In this state, the position of the water control valve 2 is too low.
To add. When performing various types of piping work around the water pipe 1, it is necessary to operate the water control valve 2 to stop the water. At such a time, the connecting rod 4 is operated. Therefore, the lid 5 on the upper part of the box 3 is opened, the operating handle 6 is projected, fitted into the operating portion 4a on the top of the joint bar 4, and rotated.

FIG. 1 is a cross-sectional view of the upper part of the joint bar 4, and FIG. 2 is a perspective view of the same, but a rectangular parallelepiped-shaped embedding hole 7 is formed at the top of the joint bar 4 (specifically, its operating portion 4a). The rectangular parallelepiped reflector 8 is also embedded in the embedding hole 7. The reflecting plate 8 may be anything as long as it reflects light, but in this example, the beads spheres 9 are evenly distributed on the substrate such as resin so that a part of the beads sphere 9 is exposed on the upper surface. The embedded one was adopted.

By the way, in the present invention, the elastic body 10 is interposed between the reflection plate 8 and the bottom of the embedding hole 7 in which the reflection plate 8 is embedded. Then, in this state, the condition is that the upper surface of the reflection plate 8 is higher than the top surface of the connecting rod 4. The elastic body 10 may be of any type as long as it has an elastic restoring force, and its material and structure are not limited, but in general, it will often be composed of a spring such as rubber or a disc spring. Furthermore, although the thickness and the like are not limited,
It is sufficient that the upper surface of the reflection plate 8 is pushed down to a position lower than the top surface of the connecting rod 4 when the handle 6 or the like is hit with a normal impact. Of course, the reflector 8 and the elastic body 10 can be formed integrally, and the
When it is embedded in the base, it can be more firmly fixed by using an adhesive or the like.

[Effect of device]

As described above, the present invention is the one described above, that is, the elastic member is attached to the bottom of the reflector 8 attached to the top of the joint rod 4.
Since it is embedded in the embedding hole 7 with 10 interposed,
Even if the handle 6 or the like hits the reflection plate 8, this is buffered to prevent damage or the like. At this time, since the upper surface of the reflecting plate 8 is set higher than the top surface of the connecting rod 4, it is difficult for dust and the like to collect on the upper surface of the connecting rod 4, and the glittering property is not impeded.
