Abstract

PURPOSE: A clamp joint pipe for waterworks is provided to minimize damage in spite of changes in surrounding environment because the pipe can be extended in the axial direction and turned in the circumferential direction. CONSTITUTION: A clamp joint pipe for waterworks comprises a main body(2) and separate clamps(3). The main body has packing grooves(2a) on both inner sides, in which a packing(5) pressed to a pipe is inserted, and holding protrusions(2b) on both sides which are inserted in holding grooves(3a) of the clamps. The clamps are coupled via coupling pieces(3b) together with bolts and nuts(6).

Description

Clamp connecting pipe for water supply

The present invention relates to a clamp joint pipe for water supply, and more particularly, to provide a clamp clamp pipe for water supply, which can provide a rigid fixed state while being easy to install, improve elasticity, and reduce cost.

In order to supply water to the home, a water pipe is buried underground, and the water pipe is piped in a configuration in which pipes are connected to a joint pipe.

The joint pipe connecting the conventional pipe is coupled to the packing surrounding the pipe to both sides of the main body, the pressure port is arranged on both sides of the main body by pressing the nut is fastened to the pipe by a nut fastened to the screw formed on the main body.

However, the conventional joint pipe for water pipes is a structure in which the pipe and the joint pipe are integrated without fluidity, so that it is difficult to cope with the deflection (position change) or expansion and contraction of the pipe due to the change of the ground, causing the pipe to break or leak. Most of the pipe leaks that occur in the high and actual phenomena are caused by the above-mentioned causes, and the industry requires a new conduit for water pipes that can solve these problems.

Accordingly, the present inventors have researched and developed the present invention to solve the above-described problems, and in the present invention, by combining the clamp is divided into a joint pipe so as to have fluidity in the axial direction and the circumferential direction and the axial perpendicular direction to the ease of construction and The present invention has been completed in view of the technical problem of the present invention by providing a clamp joint pipe for water supply capable of providing a fixed state while improving elasticity and reducing costs.

In the present invention as a means for solving the problem was configured to separate the clamp nutrient in the joint pipe body.

The coupling structure of the main body and the clamp forms a locking protrusion at the end of the main body, and the clamp is divided into a locking groove into which the locking protrusion is inserted, so that the locking protrusion is coupled to have a clearance in the axial direction and the circumferential direction in the locking groove. It was.

And another example is to form a clamp guide portion formed with a locking projection at the end portion in the axial direction in the 90 degree direction to both sides of the main body, it is possible to slide the bisected clamp formed in the clamp guide portion to form a clamping protrusion for clamping the pipe. The clamping protrusion is narrower than the space formed between the neighboring clamp guides so that play may occur in the circumferential direction and be rotated.

When using the clamp joint pipe for water supply provided by the present invention has the following effects.

-Parts can be simplified and manufacturing costs can be reduced, especially by reducing processing costs.

-Even if the surrounding environment such as ground subsidence changes during installation, the pipe can be minimized by the expansion and contraction in the axial direction and rotation in the circumferential direction.

-If the clamp slides into the clamp guide, it can reduce the risk of losing the clamp during the work.

A feature of the constant clamp joint pipe 1 provided by the present invention is that in the construction of the joint pipe 1, the clamp 3 can be clamped in a state in which the pipe 4 is separated from the main body 2. will be.

That is, in the present invention, as shown in the drawing, the main body 2, the packing 5 coupled to the packing grooves 2a formed on both inner sides of the main body 2, and closely contacted with the pipe 4, and the main body 2 The locking grooves 3a are formed to be coupled to the locking projections 2b formed to correspond to both sides of the coupling grooves, and coupling pieces 3b are formed at both ends thereof. It consists of a configuration including, the inner surface of the clamp 3 is formed with a ground projection (3c) in contact with the pipe (4).

At this time, the locking groove (3a) is to accommodate the locking projection (2b), as shown in Figure 3, the locking projection (2b) is formed large enough to move enough in the axial direction and the circumferential direction in the embedded state.

In the case where the pipe 4 is connected and buried with the constant clamp joint pipe 1 having such a configuration as shown in FIG. 2, the catching groove of the clamp 3 clamping and fixing the pipe 4 under adverse conditions such as ground subsidence ( In the state in which the engaging projection 2b is inserted in 3a), the pipe 4 is secured by being stretched in the axial direction or rotated in the circumferential direction by a free space.

Figure 4 is an exploded perspective view showing another embodiment of the water supply clamp fitting pipe provided in the present invention, Figure 5 is an assembled front sectional view of Figure 4, Figure 6 shows an assembled side sectional view of Figure 4 will be.

A feature of the constant clamp joint pipe 1 provided in another embodiment of the present invention is that in constructing the joint pipe 1, both sides of the main body 2 with the clamp 7 separated from the main body 2. It is to be able to clamp the pipe (4) in the coupled state to be slidably moved along the clamp guide portion (8) formed in the engaging projection (8a) formed in the.

That is, another embodiment of the present invention is the main body 2, the packing 5 is in close contact with the pipe (4) coupled to the coupling groove (2a) formed on both inner sides of the main body 2, and the main body (2) Clamp guide portion 8 is formed at both ends of the clamp guide portion (8a) formed at both ends in the 90-degree direction, and the engaging projection (8a) to form a groove (7b) in which the clamp guide portion 8 is inwardly formed The tension connecting portion 7a is formed, and the clamping protrusions 7c inserted into the space 8b between the clamp guide portions 8 are formed at both sides of the tension connecting portion 7a, and the engaging pieces 7d are formed at both ends. It is configured to be bisected by the bolt and the nut (9), the inner surface of the clamp 7 is formed with a ground projection (7e) in contact with the pipe (4).

At this time, the clamp guide portion 8 is embedded in the groove 7b of the tension connection portion 7a and the locking projection 8a is embedded in the space 8b between the clamp guide portions 8, and these tension connection portions 7a. As shown in FIG. 6, the groove 7b and the space 8b are largely formed to have sufficient margin in the circumferential direction in the state where the clamp guide 8 is inserted.

In the case where the pipe 4 is connected and embedded as a constant clamp joint pipe 1 having such a configuration, the clamp 7 clamping the pipe 4 is clamped under adverse conditions such as ground subsidence. Sliding movement along the (8) to expand and contract in the axial direction, in the space (8b) between the groove (8b) of the tension connecting portion (8a) and the clamp guide (8), the clamping guide (8) and the locking projection The clamp 7 is rotated in the circumferential direction even in the state in which 7c is inserted, thereby protecting the pipe 4 safely.

In addition, according to another embodiment of the present invention, when the clamp 7 fixes the pipe 4, the pipe 4 is evenly pressed on the basis of the tension connection part 7a, so that the pipe 4 may be more firmly pressurized. It can be.
