DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an insertion ring joint pipe and a coupling device therefor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an insertion ring joint pipe according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating an insertion ring joint pipe according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, the insertion ring joint pipe for prevention of falling according to an embodiment of the present invention includes a receiving pipe 100 having a larger diameter at one end, And a fixing metal piece 300 for preventing the insertion pipe 200 from being separated from the receiving pipe 100. The fixing pipe 300 has an end on the outer surface of the receiving pipe 100, A joint 400 having at least one through hole 410 which is coupled to the outer surface of the insertion pipe 200 and which surrounds the outer surface of the insertion pipe 200 and through which the fixed metal 300 passes, And a measuring unit 500 for measuring the leakage of water by measuring the air pressure and water pressure between the receiving pipe 100 and the inserting pipe 200.

The insertion-type ring joint pipe for preventing separation can prevent a plurality of pipes from being detached after being coupled to each other, and to prevent leakage.

In general, piping is necessary for transporting and moving liquids and gases, and can be suitably used for applications and fluids. A plurality of such pipes may be connected to each other and buried in the ground. In this case, it is difficult to find the cause of the leakage when leakage occurs or breakage occurs at a position where a plurality of pipes are coupled to each other. Therefore, it is difficult to repair the pipes.

The piping can be used for various purposes such as water supply, drainage, hot water supply, cooling, heating, and gas, and can be formed in various lengths and diameters.

A plurality of the pipes may be provided, and each of the pipes has a receiving portion 120 for receiving the other end of the other pipe, and the other end thereof is provided with an insertion portion accommodated in the receiving portion 120 of another pipe .

Hereinafter, in order to facilitate understanding and explanation, a pipe accommodating the other pipe at one end thereof is referred to as a "receiving pipe ", and a pipe inserted into one end of the receiving pipe is referred to as an" insertion pipe ".

The receiving pipe 100 includes a connecting part 110 formed in a slanting line so that the outer circumferential surface of the inserting pipe 200 can closely contact the outer circumferential surface of the inserting pipe 100, And an accommodating portion 120 surrounding one end of the insertion pipe 200 and coupled to the joint 400 on an outer surface thereof.

The connecting portion 110 may be formed at one end of the accommodating portion 120 formed diagonally inside the accommodating portion 120 and having a larger diameter of the accommodating pipe 100. When the insertion pipe 200 is inserted into the receiving part 120, the joining part 110 may abut the outer circumferential surface of the insertion pipe 200.

At this time, the joining portion 110 is formed in an oblique line so that the insertion pipe 200 is closely coupled to the receiving pipe 100. When the insertion pipe 200 and the receiving pipe 100 are coupled, It is possible to reduce the tolerance of the surface.

The receiving portion 120 may be formed to have a larger diameter at one end of the receiving pipe 100. The diameter of the receiving pipe 120 may be larger than the diameter of the receiving pipe 120 when the diameter of the receiving pipe 120 is larger than the diameter of the receiving pipe 120 inserted into the receiving part 120 The outer surface of the insertion tube 200 may be partially wrapped around the outer surface of the insertion tube 200.

The joint 400 may be coupled to the outer surface of the receiving part 120. The joint 400 may be welded to the outer surface of the receiving part 120 or coupled to the receiving part 120 when the receiving pipe 100 is molded It is possible to form a step with the accommodating part 120 and simultaneously form and produce.

The joint 400 may be formed to extend from the receiving portion 120 toward the insertion pipe 200 and may be formed in the same shape as the insertion pipe 200 to wrap the insertion pipe 200. .

In addition, since the joint 400 forms a step with the receiving part 120, it is possible to prevent the insertion pipe 200 from being hung on the receiving part 120 and moving toward the receiving pipe 100 And may not be released to the side of the insertion pipe 200 by the fixed metal 300 passing through the through hole 410 of the joint 400.

A plurality of through holes 410 may be formed at one end of the joint 400. A spiral groove may be formed inside the through hole 410 to increase the binding force of the fixed metal 300. [ .

Therefore, even if water pressure is generated in the inserting pipe 200 and the receiving pipe 100 by the joint 400 and the fixed metal 300, the inserting pipe 200 and the receiving pipe 100 are not leaked It is possible to prevent the insertion pipe 200 and the accommodation pipe 100 from being separated from each other.

The insertion pipe 200 includes a coupling part 210 formed in a slanting line so that one end of the insertion pipe 200 can be brought into close contact with the connection part 110 and an air tightness between the receiving pipe 100 and the insertion pipe 200 A plurality of caulkings 230 provided on the outer side of the insertion pipe 200 to raise the caulking material 230 and the caulking material 230 to prevent the caulking material 230 from moving, And a plurality of fixing bodies 220 coupled to the outer surface of the insertion pipe 200 so as to prevent the outer surface of the insertion tube 200 from moving toward the insertion tube 200.

The coupling part 210 may be provided on the outer circumferential surface of the insertion pipe 200 so as to face the joining part 110 provided at a position where the diameter of the receiving part 120 of the receiving pipe 100 is widened, And may be formed in the same slant as the joining portion 110 so as to be closely attached to the joining portion 110.

The caulking material 230 may be inserted between the joint pipe 400 and the insertion pipe 200 to prevent leakage of water through the space between the insertion pipe 200 and the joint 400, As shown in Fig.

The caulking material 230 is provided with a joint at the center of the outer side so that the caulking material 230 can be released from the outside due to frictional force generated when the inserting pipe 200 and the receiving pipe 100 are joined. And distortion may not occur with respect to shrinkage and expansion caused by the external temperature.

The caulking material 230 may be curved at both ends around the joint so that the frictional force of the caulking material 230 can be reduced when the insertion pipe 200 is inserted into the receiving pipe 100.

The fixing member 220 is provided on both sides of the caulking material 230 to prevent the caulking material 230 from moving and to prevent the caulking material 230 from moving on the outer circumferential surface of the receiving part 120, So as not to move to the side of the inserting pipe 200.

When the outer circumferential surface of the receiving part 120 is moved to the side of the insertion pipe 200 by the water pressure, the fixing part 220 is inserted into the receiving part 120, Welded to the outer circumferential surface and molded together with the receiving pipe 100.

The fixture 220 may be provided at one end of the insertion pipe 200 so as to be positioned inside the joint 400 coupled to the outside of the accommodating portion 120, Such as a circular ring or a square cross section, and may be coupled to the outer surface of the insertion pipe 200. [

As a method of checking the leakage of the measurement space 540 in the measurement unit 500, the injection unit 520 may be coupled to the injection hole 510 to inject air into the measurement space 540 .

When the water in the insertion pipe 200 and the water in the water pipe 100 leaks into the measurement space 540 through the caulking material 230 on the side of the water pipe 100, The leakage can be extended to the outside by the pressure by the air injected by the air. It is possible to determine the leakage of the inserting pipe 200 and the receiving pipe 100 and take measures.

The stopper 530 may be coupled to the injection hole 510 when the injection device 520 is not used in the injection hole 510. The stopper 530 may be inserted into the injection hole 510, 510, the injection holes 510 may be clogged by foreign substances.
