Fig. 1 is an exploded view of a pipe joint according to the present invention, fig. 2 is a combination view of the pipe joint according to the present invention, and fig. 3 is a sectional view of the pipe joint according to the present invention.

As shown in fig. 1 to 3, the pipe coupling joint according to the present invention includes a body 200 having a hollow body shape, a coupling surrounding a pipe inserted into both ends of the body 200 and the outer circumference of the body 200 so that the pipe is coupled to the body 200, and a packing member 100 installed to require watertightness between the coupling and the pipe.

As shown in fig. 4, at both ends of the body 200 are formed protrusion rings 210 protruding to the outside along the outer side circumference of the body 200.

As shown in fig. 5, the coupling of the present invention is formed by coupling an upper coupling 310 and a lower coupling 320 having a semicircular shape in a circular shape, flanges 330 are formed at both ends of the upper coupling 310 and the lower coupling 320, bolt holes 340 are formed in the flanges 330, and bolts 400 are inserted into the bolt holes 340 formed in the flanges 330, thereby coupling the upper coupling 310 and the lower coupling 320 to each other.

At this time, a first mounting groove 350 and a second mounting groove 360 are formed on the inner circumference of the upper coupling 310 and the lower coupling 320, the packing member 100 is mounted to the first mounting groove 350, and the protrusion ring 210 of the body 200 is mounted to the second mounting groove 360.

As shown in fig. 6 to 9, the sealing member 100 includes a sealing member body 110 having a hollow shape and a wing 120 bent toward an inner peripheral edge of the sealing member body 110, so that a fluid housing 140 serving as a space for housing a fluid is formed between the wing 120 and an inner surface of the sealing member body 110.

And, prevention weirs 123 protruding toward the center of the packing member 100 are formed at the distal end portions of the wing portions 120, so that pipes inserted into both ends of the packing member 100 are inserted with the distal end portions contacting the prevention weirs 123 of the packing member 100, thereby maintaining watertightness and the degree of insertion to a certain extent.

In particular, even if the wing 120 is brought into contact with the inner surface of the package main body 110 by means of a tube inserted into the package main body 110 of the package 100, in order to allow fluid to flow into the fluid housing part 140, the first flow path hole 121 communicating with the fluid housing part 140 is formed at a bent portion formed between the wing 120 and the prevention ridge 123.

Further, the first flow path hole 121 of the wing 120 is formed in a semicircular shape, a protruding sill 130 protruding inward is formed on the inner surface of the sealing member body 110 contacting the wing 120, and a second flow path hole 131 having a semicircular shape corresponding to the first flow path hole 121 of the wing 120 is formed on the protruding sill 130.

Thus, if the distal end portion of the wing 120 is in contact with the protruding sill 130 by means of a tube inserted into the inside of the body, the first and second flow path holes 121 and 131 are formed in a circular shape.

To describe the packing member 100 in more detail, the packing member 100 is configured to prevent a fluid flowing inside a tube from leaking to the outside by housing the tube in an inner hollow hole.

In particular, the sealing member 100 of the present invention has wing portions 120 bent toward the inner peripheral edge of the sealing member body 110 formed at both ends of the hollow sealing member body 110, and a fluid housing portion 140 as a space for housing a fluid is formed between the wing portions 120 and the inner surface of the sealing member body 110.

In other words, one end of the wing 120 is integrally formed at the end of the packing member body 110, and the other end is bent toward the inner circumference of the packing member body 110, and a space is formed between the wing 120 and the inner side surface of the packing member body 110 so that fluid leaking from the tube can be received in the space, thereby being referred to as a fluid receiving part 140.

At this time, even if the distal end portion of the wing 120 is brought into contact with the inner surface of the main body by means of the tube inserted into the package main body 110, the first flow path hole 121 communicating with the fluid housing portion 140 is formed at the distal end portion of the wing 120 so that the fluid can flow into the fluid housing portion 140.

The first flow path hole 121 of the wing 120 is formed in a semicircular shape, a protruding threshold 130 protruding inward is formed on the inner surface of the sealing member body 110 contacting the wing 120, and a second flow path hole 131 having a semicircular shape corresponding to the first flow path hole 121 of the wing 120 is formed on the protruding threshold 130.

The plurality of first and second flow path holes 121 and 131 are formed at regular intervals along the circumferential direction of the wing 120 and the protruding sill 130, so that the fluid is easily introduced into the fluid housing part 140.

Further, the wing part 120 is formed with a plurality of short ridges 122 at an outer side surface contacting the tube, the short ridges 122 being formed obliquely toward an inner circumferential center part of the packing member 100, thereby preventing the wing part 120 from being folded toward an outer direction when the tube is inserted.

Preferably, the packing member 100 of the present invention is made of synthetic rubber or synthetic resin.

As a result, if the fluid flowing through the inside of the pipe leaks through the first flow path hole 121 and then flows into the fluid housing unit 140 by the packing member 100, fluid pressure is generated inside the fluid housing unit 140, and the wing units 120 are more firmly attached to the outer surface of the pipe, thereby achieving a watertight operation of the pipe.

Further, the prevention ridges 123 formed at the distal end portions of the respective wings 120 to protrude toward the central portion of the packing member 100 are closely attached to each other by means of the tubes respectively inserted, so that the water tightness of the tubes can be more maintained.

Further, the packing member body 110, that is, the first body 111 having a relatively large thickness and the second body 112 having a relatively smaller thickness than the first body 111 are continuously formed, and the plurality of wrinkles 113 are formed in the outer surface of the packing member body 110 in the circumferential direction, thereby being able to receive the fluid pressure generated when the fluid leaks from the pipe.
