In order to provide a single pipe or provide assembly of more than one pipe, the body 50 has at least one opening, and a ring seat 501 and A coupling portion 502 is provided with a seal ring 51 at the position of the ring seat portion 501, the seal ring 51 abuts against the ring seat portion 501, and an assembly member 54 in a ring shape is provided, and a retaining ring 55 is penetrated inside In addition, a binding member 53 and a firmware 52 are provided in sequence. When the assembly 54 is installed at the joint portion 502 of the body 50, the sealing member 52 is pressed against the sealing ring 51, and the tube 60 is inserted into the body 50 During positioning, the pipe 60 is bitten and positioned by the teeth of the restraint 53, and the assembly of the pipe joint and the pipe 60 can be completed.

Since the sealing ring 51 provided in the prior art pipe joint is unable to move due to the combined positioning of the sealing member 52, and the pipe member 60 is positioned by the restraining member 53, the displacement between the pipe member 60 and the pipe joint cannot be generated. The sealing ring 51 between the ring seat 501, the sealing member 52 and the outer wall surface of the pipe 60 is often pressed by a certain external force. After a period of use in the piping system, the sealing ring 51 will produce elastic fatigue, making the pipe The sealing effect between the joint and the pipe fitting is reduced, which will seriously cause problems such as leakage. Furthermore, the prior art pipe joint is composed of multiple components and can be assembled with the pipe fitting, so there is a complex structure and high cost Disadvantages.

In view of the problems and shortcomings existing in the implementation and use of the prior art, the new model was re-created in the inner ring chamber of the hollow body, with mutually parallel restraint pieces and sealing rings. After the pipe piece and the restraint piece are combined, the pipe piece is changed by water pressure It can be slightly displaced relative to the body, so that the restraint piece reciprocally presses the sealing ring to prevent the elasticity of the sealing seal from fatigue, and to ensure the tightness between the pipe joint and the pipe fitting.

In order to achieve the aforementioned new purpose, the technical means used in the present invention is to provide a pipe joint, which includes a body, a restraining member and a sealing ring; the body is a hollow body with an opening at one end and the other end A closed end, the body adjacent to the opening forms a mounting portion, the mounting portion protrudes radially outward from the body and forms an inner ring chamber inside, the inner ring chamber is in communication with the opening, the inner ring The chamber is an annular space, and its two side wall surfaces are respectively a first abutting surface and a second abutting surface, and the opening is located at the first abutting surface; the restraining member is a hollow annular piece, It has a ring portion, which protrudes from the inner edge to form a plurality of teeth; the sealing ring is a hollow ring body, which is arranged in parallel with the restraining member in the inner ring chamber of the mounting portion, the restraining member is adjacent Located at the second abutment surface, the seal ring is adjacent to the first abutment on one side, and the ring portion of the restraining member abuts against the other side.

In the pipe joint, each tooth portion of the restraining member is arranged at intervals and protrudes obliquely toward the center extension line of the restraining member, and its protruding direction is away from the opening.

The pipe joint, wherein the closed end of the body is formed with another opening, and further includes another restraining member and another sealing ring; the body is formed with another mounting portion adjacent to the other opening, The other mounting portion protrudes radially outward from the body and forms another inner ring chamber inside, the other inner ring chamber is in communication with the other opening, the other restraining member and the other sealing ring To be arranged side by side in the other inner ring chamber, the other restraining member is a hollow ring-shaped sheet body and has a ring portion, the ring portion of the other restraining member protrudes from the inner edge to form a plurality of tooth portions, and the other Each tooth portion of the restraining member is arranged at intervals and protrudes obliquely toward the center extension line of the other restraining member, and its protruding direction is away from the other opening position, and one side of the other sealing ring is adjacent to the other The other side of the opening is adjacent to the ring of the other restraint.

With the use of the aforementioned technical means, when the tube is inserted into the body, the tube will be positioned by the teeth of the restraining element, because the sealing ring provided inside the inner ring chamber is adjacent to the opening And the other side is in contact with the restraining member, and the pressure change caused by the flow of the fluid inside the pipe will cause the relative reciprocating movement between the pipe and the body. At this time, the ring of the restraining member can be reciprocally pressed or slightly loosened In this way, the proper sealing effect of the sealing ring can be maintained. Furthermore, the sealing ring is pressed or loosed reciprocally even after long-term use, it can still maintain its elasticity and have a sealing effect, which can avoid its elastic fatigue. When the new type is used, when the internal pressure of the pipe body is greater, the position of the ring portion of the restraining member can be forced to form a larger thrust to push against the sealing ring, so as to improve the sealing effect formed by the sealing ring. And because the overall structure uses fewer components, it has the practical effect of convenient assembly.
