Description

[0001]
[Industrial applications]
The present invention relates to a pipe connection release of a water meter used for installing a water meter in a place where an installation space, a pipe direction, and the like are restricted by an installation environment such as an apartment house.
[0002]
[Prior art]
Conventionally, this type of pipe-coupled release has a holder that holds the water meter from both sides and is fixed to both ends of the raised release body, and the release body is used in a fixed shape that can be mounted in a specific direction. The meters are connected to the structural pipes on both sides, so that the meters are supported and fixed by the structural pipes.
[0003]
Also, when the meter is supported and fixed to the floor or wall surface by release, the receiving holder and tightening holder for fitting the water meter are configured so that they cannot be easily removed from the release body. Is attached to the release body so as to be configured as a holder unit.
[0004]
Furthermore, since the water meter ends are fixedly fitted and fitted in both holders, a pipe connection adjustment mechanism such as a check valve unit is built in the holders and integrally formed. .
[0005]
[Problems to be solved by the invention]
As described above, in the conventional pipe connection release of a water meter, a fastening holder base that moves forward and backward is mounted on one end of a release body, and a receiving holder base that faces the other end is detachably fitted to the other end of the water meter. The purpose is to clamp the water meter between the receiving holder and the tightening holder by fitting one end of the meter to the holder base and fitting the other end into the tightening holder base to advance the tightening holder base. Therefore, the holder structure itself cannot be attached to a wall surface or a floor surface in a stable form.
[0006]
In addition, the conventional meter release has a base body that fixes the holder as the main body and the release holder is attached to this, so the shape and configuration of the base body are fixed, and it can not respond to the setting environment That leaves the problem.
[0007]
Furthermore, since the holder structure holds the meter from both ends and pushes the tightening mechanism to tighten and fix it, there is no base to support the heavy meter during the clamping work, and the mating core of the meter A great deal of effort and skill is required to fit the boss into the holder core.
[0008]
[Means for Solving the Problems]
The present invention is intended to address the above-described problem, in which a pair of release holders are independently supported by legs, and are connected to support rod fastening wings provided on both sides thereof by a support rod of a predetermined length. The support rod and the holder are configured as selectable members so as to constitute the release body.
[0009]
Provide a support tongue piece that joins the lower end shape of the fitting end that receives and supports the meter mating end in the fastening joint that receives the meter end of the release holder, and drops the meter end to be joined from above Thereby, the bonded core can be joined to the holder core.
[0010]
Furthermore, at both ends of the meter, a pair of attachments that are configured separately from the release main body and include a connection adjustment mechanism with a water pipe, such as a check valve unit, and are attached to the release holder, are mounted, The structure of the release holder has been distributed to attachments to give the entire release a fluid adaptability.
[0011]
The fastening mechanism of the release holder that presses the end of the water meter and clamps the meter is retracted by the cam cylinder or stopper that engages the operating cylinder with the fastening cylinder urged in the forward direction by the spring, When the meter is fitted between the opposed holders, the fastening cylinder is advanced by the biasing force of the spring by operating the cam mechanism or releasing the stopper, and the meter is fastened and fixed. Even when an attachment that is formed on the body and is unitized as a detachable attachment is fitted, the tightening force does not loosen due to the spring tightening in which the pressing force is always exerted by the bias of the spring.
[0012]
Furthermore, the length of the support rod fastening wings provided on both sides of the release holder is made longer according to the installation environment of the water meter, and one is made shorter so that the mounting is stabilized and the molding efficiency is improved. I made it. The support rod, which is fastened to the fastening wing and connects the release holder, also functions as a stopper that regulates the rotation around the release of the water meter to be fitted from both sides, so the protrusion length of the support rod fastening wing Is changed to change the rotation range of the fitted meter.
[0013]

The upstream holder 1a is provided with a leg 12 supporting the main body at its lower end and standing independently, a fitting portion 13 having an inner end fitted to the end of the meter A, and a water stopcock unit 3 fitted behind it. A pipe connection structure 14 is provided at an outer end thereof, and is connected to a water supply pipe.
[0015]
Like the holder 1a, the lower flow rate holder 1b is provided with a leg 12 that supports the main body at its lower end and is self-supporting, and a fitting portion 13 that is fitted to an end of the meter A at an inner end thereof. 13 is fitted with a tightening cylinder 4 that moves forward and backward with respect to the end mating end of the meter A, and a pipe connecting structure 14 is provided at an outer end thereof so as to be connected to a water supply branch pipe. ing.
[0016]
The fastening cylinder 4 is always urged in the forward direction by a spring 41 and is retracted by a cam mechanism 42 or a stopper 44 engaged with the operation handle 43. When the meter A is fitted between the holders 1a and 1b, the cam mechanism is Or the operation of the stopper release button 45, the compression control of the spring 41 is released, and the urging force of the spring causes the tightening cylinder 4 to move forward and the meter to be tightened and fixed.
[0017]
That is, when the fastening cylinder 4 is retracted to the position of the stopper 44 by the rotation of the handle 43, the stopper 44 is locked to the tip of the fastening cylinder 4 and the urging force of the spring is suppressed. When the release button 45 is pressed, the locking of the stopper is released, and the fastening cylinder advances at a stretch. If the release button 45 is set to the meter A fitting fitting portion 13 of the holder 1b, and the button 45 is pressed by the drop fitting of the meter A to release the engagement of the stopper, the fitting of the meter can be prevented. At the same time, jump fastening can be performed. Since the retracted state of the fastening cylinder can be maintained only by the cam mechanism 42, it is needless to say that the jump fastening by the engagement of the stopper does not always have to be performed.
[0018]
The support tongue pieces 5 which are joined to the lower surface of the fitting end 15 which receives and supports the meter fitting end are provided at the meter A fitting fitting portions 13 of the holders 1a and 1b, and the meter end portions to be fitted are provided.

When the stopcock is opened by moving, the water flow passes through the meter A from the flow path of the holder 1a, flows into the flow path of the holder 1b, and the flow rate and the like are measured.
[0025]
When the meter A is removed for replacement or the like, the open / close handle 31 of the water stopcock unit 3 is turned to close the water stopcock, and the operation handle 43 is turned to resist the urging of the spring 41. Then, the fastening tube 4 is moved backward to remove the meter A. Also in this case, the meter A does not drop from the release due to the presence of the support tongue 5 and the auxiliary support structure 7.
[0026]
Since the present invention is configured as described above, the release holder and the connecting support rod connecting the release holder become a component member that can be assembled on site, and if the length of the meter A can be determined, the release body needs to be transported in a bulky assembled state. And the work procedure can be carried out in a fluid manner.
[0027]
Furthermore, since the meter holder is not integrated with the base body, it is made into a component as a release holder, so that the connecting support rod can be freely selected such as stainless steel tube and square material, and a wide range of configurations can be configured according to the setting environment. This has the effects described above.
