JP3745995B2 - A holder for preventing water from rotating together - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, the amount of water held by the water meter is prevented in order to prevent the water meter from rotating around when the nut is tightened or loosened in order to connect or remove the water meter to a pipe such as tap water. The present invention relates to a holder for preventing co-rotation of water containers.
[0002]
[Prior art]
The water meter is attached so that tap water flows in and out of the water pipe in order to measure the amount of tap water used.
[0003]
FIG. 4 is an exploded perspective view for explaining the connection between the water meter and the pipe. In FIG. 4A, spiral screws 32 are formed on the outer circumferences of both sides of the water meter 3. A dedicated rubber packing 40 is sandwiched between the inflow side joint 33 into which the tap water flows in and the inflow side joint 33 between the nut 36 attached to the outflow side from which the tap water of the dedicated stopcock 35 flows out. By rotating 36, the water meter 3 and the stop cock 35 are connected and fixed.
[0004]
A spiral screw 32 is formed on the outer periphery of the inflow side joint 37 of the water stop cock 35. A dedicated pipe 39 with a collar is inserted into the guide nut 38 shown in FIG. 4 (b) to stop the dedicated rubber packing 40. The inlet side joint 37 of the faucet 35 and the collar portion of the flanged pipe 39 are brought into close contact with each other, the guide nut 38 is rotated, and the water stopcock 35 and the dedicated collared pipe 39 are connected and fixed.
[0005]
The connection and fixing between the outflow side joint 34 through which the tap water of the water meter 3 flows out and the flanged pipe 39 are performed in the same manner as the connection and fixing of the inflow side joint 37 of the water stopcock 35 and the flanged pipe 39. When removing the water meter 3 connected and fixed to the water stopcock 35 and the flanged pipe 39, the nut 36 and the guide nut 38 are reversely rotated with a spanner and removed.
[0006]
[Problems to be solved by the invention]
To remove the water meter for replacement, etc., when rotating the nut with a spanner, press the water meter by hand to prevent the water meter from rotating together with the nut. I try not to rotate.
[0007]
However, because the water meter and the nut are fixed due to rusting and strong tightening, the water meter cannot be rotated together by simply holding it down by hand, and the nut cannot be easily loosened, which is troublesome. In addition, when attaching a water meter, since it rotates together with the nut when tightening, it may take time and labor to tighten it tightly.
[0008]
Therefore, the present invention can prevent the metering device from rotating together when rotating the nut, and a metering device co-rotation preventing holding tool that does not require time and effort to loosen or tighten the nut. It is to provide.
[0009]
[Means for Solving the Problems]
The present invention relates to a water meter co-rotation prevention holder for holding a water meter in order to prevent the water meter from co-rotating when a nut connecting a water meter and a pipe is rotated. The water meter holding part for holding the water meter is provided at the lower end of the water meter, the water meter holding part is provided at the lower end of the handle, and the water meter holding member for holding the side of the water meter, It comprises an arm that supports a hook that presses the side opposite to the portion and is attached to the handle so as to be pivotable in the vertical direction.
[0010]
The hook is slidably supported by an arm, and a hook lock lever that locks the position of the hook so as to fit a water meter of a predetermined size by sliding the hook is pivotally supported in a vertical direction. The hook lock lever is provided with a lock pin biased to the lock hole side, which engages with a lock hole formed at an interval in accordance with a water meter of a predetermined size on the arm. It may be configured.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
1 is a perspective view of a holder for preventing co-rotation of a water meter according to the present invention, FIG. 2 (a) is a front view thereof, (b) is a view of an arm viewed from below, and (c) is a front view of a hook lock lever. FIG. 4D is a plan view of the arm.
[0012]
A grip 2 that holds the handle 1 is provided at the upper end portion of the rod-like handle 1, and a water meter holding portion 4 that holds the water meter 3 is provided at the lower end portion.
[0013]
A steel pipe or a steel bar is used for the handle 1. The grip 2 determines the position of the handle 1 and uses an elastic body such as rubber having irregularities and grooves to make it easy to hold and slip.
[0014]
The water meter holding part 4 is provided with a water meter holding member 5 that extends horizontally at the lower end of the handle 1, and an arm 7 that slidably supports the hook 6 can be pivoted up and down by a hinge 8 on the handle 1. It is attached. The tip of the water meter holding member 5 forms an arc-shaped recess so that the side of the water meter 3 can be easily pressed. In addition, when preparing the holding | maintenance tool for co-rotation of a water meter for every water meter of various magnitude | sizes, you may fix or integrally provide the hook 6 without sliding to the arm 7. FIG.
[0015]
The hook 6 is provided with a hook lock lever 9 that slides the hook 6 so as to fit the water meter 3 of various sizes and locks the position of the hook 6.
[0016]
The hook lock lever 9 is pivotally supported on the hook 6 by pins 11 so that pin support pieces 10 formed on both sides of the center of the hook lock lever 9 can rotate with respect to the hook 6. The hook lock lever 9 is provided with a lock pin 12 on one side of the pin 11 and a spring 14 via a spring guide 13 on the other side.
[0017]
As shown in FIG. 2, the lock pin 12 extends from the hole 15 of the hook 6 and engages with the lock hole 16 of the arm 7. The lock pin 12 is urged toward the lock hole 16 by a spring 14, and the hook 6 can be slid by being released from the lock hole 16 by pressing the spring 14 side. The front end of the hook 6 is bent inward to form a holding part 17 that holds down the lower part of the meter frame 3 a of the water meter 3. The tip of the pressing portion 17 forms an arc-shaped recess so that the side of the water meter 3 can be easily pressed.
[0018]
The lock hole 16 of the arm 7 is provided at intervals according to the water meter 3 of various sizes.
[0019]
Next, the usage method of the holder for co-rotation prevention of the water meter of this invention is demonstrated.
[0020]
FIG. 3 is a diagram showing a procedure for using the holding device for preventing co-rotation of the water meter of the present invention.
[0021]
(1) Holding the spring 14 of the hook lock lever 9 and pulling the lock pin 12 out of the lock hole 16 of the arm 7 and sliding the hook 6, the spring 14 is returned to the original position at a position matching the size of the water meter 3. Then, the lock pin 12 is inserted into the lock hole 16 (see FIG. 3A).
[0022]
(2) With the arm 7 rotated upward, the water meter holding member 5 is placed on one side of the water meter on the opposite side of the nut rotation direction, the arm 7 is rotated downward, and the hook The pressing portion 17 at the tip of 6 is applied to the lower side of the meter frame 3a on the other side of the water meter 3 (see FIG. 3B). When the handle 1 is set to be vertical, the metering device co-rotation preventing holder is held by the metering device 3 (see FIG. 3C).
[0023]
(3) Hold the grip 2 of the handle 1 in a state where the water meter 3 is held by the holder for preventing the water meter from rotating together, and rotate the nut with a spanner. If the handle receiving force is applied in the direction opposite to the rotation direction of the nut, the nut can be rotated while preventing the water meter from rotating together without requiring a large force due to the lever action of the handle. .
[0024]
【The invention's effect】
According to the present invention, since the handle can hold the water meter with a large force by the lever principle, the nut can be rotated without rotating the water meter by rotating the nut. Therefore, the work is not time-consuming and the work efficiency is improved as compared with the conventional case.
