FIG. 1 shows an overall assembly view of a base for connection installation. The base is composed of two hollow pipe-shaped (beam-shaped) base bodies 1, 1 and a pair mounted on both ends of the base bodies 1, 1. It is composed of holders 2 and 2a. The configuration of each of these members will be described with reference to FIG.

The base body 1, 1 is composed of hollow pipes 4, 4 at the central portion thereof, but steps 24, ... Are formed at both end positions thereof, and shaft portions 5, 5, 5 a having a smaller diameter than the pipe 4. , 5a are provided. Reference numeral 6 indicates a male screw portion engraved on each of the shaft portions 5. Reference numeral 7 denotes a plate for supporting the flowmeter 8 to be mounted, which is mounted across both base bodies 1 and 1.

The holder 2 is provided with the base body 1, 1 at the bottom of a bifurcated supporting leg 10 which is continuously provided at the bottom of a tubular portion 9 along the horizontal direction.
The shaft portions 5, 5 are provided with hole portions 11, 11 which can be fitted onto the shaft portions 5, 5. Reference numeral 12 denotes a flange that is continuously provided on the outer end side of the cylindrical body portion 9. Reference numeral 13 denotes a male screw portion engraved on the outer periphery of the inner end of the tubular body portion 9, and 14 denotes a convex portion for locking a lever, which will be described later, provided on the upper surface of the tubular body portion 9 so as to project.

In FIG. 1, reference numeral 17 denotes a connecting pipe body slidably fitted to the inner end side of the tubular body portion 9 of the holder 2, and the tubular body portion 9
A spring 18 inserted into the inside of the container constantly biases the front side of the arrow a (the side where the flowmeter 8 is installed). Reference numeral 19 denotes a stopper for engaging the step portion 20 of the tubular body 17 to prevent the tubular body 17 from being pulled out toward the front side.

Reference numeral 21 denotes a receiving plate which is integrally or separately formed on the tip end side of the tubular body 17 and which is provided in a forwardly protruding manner and has a substantially arcuate cross section. Reference numeral 22 is a water shutoff valve such as a ball valve which is connected to the tubular portion 9 via a flange 12.

Further, the other holder 2a is obtained by fitting a cylindrical body portion 9a, which is separately processed and manufactured, into a hole portion 32 formed in the upper portion of the supporting leg portion 10a, and tightened with a nut 33. Is. 11a, 11a
Are two hole portions penetrating the lower side of the bifurcated supporting leg portion 10a, which can be fitted to the shaft portions 5a and 5a of the base bodies 1 and 1, respectively. Reference numeral 15 is a male screw portion engraved on the outer periphery of the outer end of the tubular portion 9a. Reference numeral 16 is a receiving plate having a substantially arcuate cross section, which is horizontally projected on the other end side. Reference numeral 23 is a check valve mounted inside the cylindrical portion 9a, which allows only water to pass in the direction of arrow b.

This embodiment comprises the above-mentioned components. In assembling the components, first, the shaft portions 5, 5a of the two base bodies 1, 1 are fitted into the hole portions 11, 11a of the holders 2, 2a, respectively. Then, after that, the nuts 25 are screwed to the shaft portions 5 of the base bodies 1 and 1, and the leg portions 10 and 10a of the holder are locked to the stepped portions 24 and tightened with the nuts 25. As a result, the pair of holders 2 and 2a are connected and fixed via the two base bodies 1 and 1, and at the same time, the base bodies 1 and 1 are firmly assembled and maintained in parallel with each other.

Since the mutual dimension L of the pair of holders 2 and 2a is determined by the size of the mutual dimension La of the stepped portions 24 and 24 of each base body 1, the dimension La is set to a predetermined value. If this is done, the distance L between the holders 2 and 2a can be easily set to the optimum state for connecting and mounting the flowmeter 8.

Also, the distance La between the steps 24, 24 of the base body 1, 1 is La.
If different ones are manufactured separately, the same holders 2 and 2a will be used and the set distance L between both holders 2 and 2a will be L.
It will be possible to manufacture multiple types of bases that differ. In this case, the same holders 2 and 2a as described above may be used, and it is not necessary to newly manufacture the holders 2 and 2a. Tube parts 8 at the left and right ends of the flow meter 8 to be connected and connected
When the distance between a and 8b is changed, only the base bodies 1 and 1 need be changed.

Furthermore, since the base body 1, 1 of the base is composed of two pipe-shaped members, its strength is large,
Moreover, it is lightweight. Further, since the two pipe-shaped members are juxtaposed at appropriate intervals, the stability when stored in the pit is also excellent.

In addition, the base having the above structure does not cause any inconvenience in handling. That is, first, in FIG. 1, when connecting the pipes 26, 26a for water supply piping, the pipe 26 on the upstream side is connected.
Is threadedly connected to the water shutoff valve 22, and the other downstream pipe 26a
May be screwed to the holder 2a. Next, the flow meter 8
At the time of connecting and mounting, the connecting pipe body 17 on the holder 2 side is retracted in the direction opposite to the arrow a direction against the elastic force of the spring 18, and then the pipe body portions 8a at the left and right ends of the flowmeter 8 are mounted. , 8b may be installed on the receiving plates 21, 16 protruding from the connecting pipe body 17 and the holder 2a, respectively. When the backward movement of the connecting pipe body 17 is released in this state, the pipe body 17 comes into contact with the pipe body portion 8a of the flowmeter 8 by the elastic force as shown in FIG. 1B, and the other pipe body portion 8b. Is contacted with and connected to the cylindrical body portion 9a of the holder 2a. As a result, the flowmeter 8 is connected to the water pipe through the pair of holders 2 and 2a.
Pipes are properly connected between 26 and 26a. Both tube parts of flow meter 8
If the packings 27, 27 for sealing are attached to 8a, 8b, it is possible to appropriately prevent water leakage.

When removing the flowmeter 8, the connecting pipe 17 may be retracted to separate from the pipe portion 8a of the flowmeter 8. At that time, if the water stop valve 22 on the upstream side is closed, the holder 2 and There is no water leakage from the pipe 17. On the other hand, since the check valve 23 is provided in the holder 2a on the downstream side, undue water leakage from the holder 2a does not occur.

Further, when the connecting pipe body 17 is retracted against the elastic force of the spring 18, the work is performed by, for example, the tool 28 shown in FIG.
Connect the two link members 29 and 30 of the
4 and the engaging portions 31 provided on both sides of the connecting pipe body 17, respectively, and one of the link members 29 is pushed in the direction of arrow b. If this means is adopted, the retracting operation of the connecting pipe body 17 can be performed very easily by using the lever principle.

In the above embodiment, the two hollow pipe-shaped members are used as the base body, and the holders 2 and 2a are fitted to the ends thereof and tightened with the nuts. Although there is an advantage that the work is easy and maintenance and repair are convenient, the present invention according to the first claim is not necessarily limited to such a configuration.

For example, as shown in FIG. 4, the holders 2 and 2a may be attached to both ends of the base body 1 which is formed as a single body by using bolts 32. In the present invention as set forth in claim 1, the means for attaching the holders 2, 2a to the base body 1 is not specified at all, and various other means other than that can be applied.

Further, in the first claim, the base body 1 is not limited to the hollow pipe shape, and a solid rod-shaped member or other plate-shaped body may be used, and the specific number thereof. It doesn't matter. The point is that the base body may be formed separately from the pair of holders 2 and 2a.

Further, in the above embodiment, the holder 2 on one side is provided with the connecting pipe 17 reciprocally, or the holders 2 and 2a are provided with the water shutoff valve 22 and the check valve 23 to attach and detach the fluid device 8. For convenience of work, such means are not essential in the first claim. It may be provided if necessary. The fluid device 8 may be mounted between the tubular portions 9 and 9a provided at fixed positions without using the connecting pipe body 17 which can be freely reciprocated. Further, as shown in FIG. 5, a means may be applied in which the check valve 23 is provided in the pipe body portion 8b of the fluid device 8 and the check valve is not provided in the holder 2a.

Further, the present invention is applied to the cylindrical portions 9 and 9a of the holders 2 and 2a and the supporting legs
The specific configuration of 10, 10a is not limited as in the above embodiment. The tubular body portions 9 and 9a and the supporting leg portions 10 and 10a may be integrated or separate bodies, and their specific shapes and materials are not limited at all.

Besides, in the present invention, the configuration of each part can be arbitrarily changed in design, and needless to say, the specific type of the fluid device 8 is not specified.

(Effects of the Invention) As described above, the present invention comprises a pair of holders having a tubular body portion for connecting a fluid equipment and a pipe body for water supply piping, and a base body, which are separate bodies. Even if the size of the fluid device to be mounted is changed, all parts are integrally molded by conventional casting, etc., because the fluid device can be connected and mounted so that it can be assembled integrally as much as possible. There is no need to re-manufacture the entire base as was done previously, but by changing only the base body, it became possible to properly mount fluid devices of different sizes.

As a result, according to the present invention, as compared with the conventional one in which the entire base is remanufactured, the manufacturing cost thereof is remarkably reduced, and various types of fluid devices can be dealt with.

In addition, it can be made stronger in terms of strength than the conventional one that was formed as a whole by casting.
There is also an advantage that the use durability can be improved.

Further, the base body of the present invention is composed of two pipe-shaped or rod-shaped members, and the supporting leg portions of the holder are fitted to the shaft portions provided at both ends thereof and fastened with the nuts. According to the second means, not only the weight and strength of the base body can be improved at the same time, but also the assembling work is very easy without requiring any special skill or tool, and the disassembling work is also possible. Can be easily carried out, parts of each part can be suitably exchanged, and the handleability thereof can be made excellent.

Also, as an important effect, since the pair of holders are tightened with the nuts while being locked to the stepped portion formed on the base body, the mutual spacing between the pair of holders is unduly displaced due to the reduction of the tightening of the nuts. There is also an advantage that the holder interval can be reliably and easily set to a desired accurate dimension and the fluid devices can be appropriately connected.

Further, a fluid pipe is connected to one holder of the present invention so as to be slidably movable, and the fluid pipe is connected to and detachable from the pipe portion on one end side of the fluid device. According to this means, the fluid pipe can be easily attached and detached by sliding the connecting pipe, which is convenient, and the holder of the present invention is provided with a water stop valve and a check valve. There is a practical advantage that it is possible to accurately prevent the generation of unwarranted water leakage when the fluid device is attached or detached, which is convenient for work.
