A novel pipe connecting structure according to an embodiment of the present invention is described below with reference to fig. 1 to 6 of the accompanying drawings, including: the pipe fitting comprises a first pipe 1, a second pipe 5, a clamping ring 9, a sealing ring 12, a first sleeve 3 and a second sleeve 7;

as shown in fig. 1-3, the first sleeve 3 is disposed in the wall of the first tube 1 and adjacent to the socket end 2 of the first tube 1, the second sleeve 7 is disposed in the wall of the second tube 5 and adjacent to the socket end 6 of the second tube 5, the outer peripheral wall of the first sleeve 3 is provided with an annular first slot 4, and the inner peripheral wall of the second sleeve 7 is provided with an annular second slot 8.

Specifically, the first pipe 1 and the second pipe 5 are plastic pipes made of a PE material (polyethylene) or a HDPE material (high density polyethylene). The first sleeve 3 and the first pipe 1 are matched in many ways, for example, the first sleeve 3 can be directly embedded in the pipe wall of the first pipe 1, or the first sleeve 3 can be embedded in the outer peripheral wall of the first pipe 1; correspondingly, the matching form of the second sleeve 7 and the second pipe 5 is many, for example, the second sleeve 7 may be directly embedded in the pipe wall of the second pipe 5, or the second sleeve 7 may be embedded in the inner peripheral wall of the second pipe 5. However, in any configuration, the first card slot 4 and the second card slot 8 are exposed.

As shown in fig. 2-3, the first sleeve 3 and the second sleeve 7 have the same structure, and the difference is mainly that the first engaging groove 4 is disposed on the outer peripheral wall of the first sleeve 3, the second engaging groove 8 is disposed on the inner peripheral wall of the second sleeve 7, the first sleeve 3 and the second sleeve 7 are both made of metal, the metal material is not easily broken and damaged, and the first sleeve 3 and the second sleeve 7 are both provided with a plurality of holes to form a latticed skeleton structure, which is convenient for manufacturing and saves material.

The first sleeve 3 and the second sleeve 7 are both pre-embedded in the pipe when the pipe is processed, wherein the thickness of the first sleeve 3 is one third of the thickness of the first pipe 1, the thickness of the second sleeve 7 is one third of the thickness of the second pipe 5, when the first sleeve 3 is embedded on the peripheral wall of the first pipe 1, the peripheral wall of the first sleeve 3 is flush with the peripheral wall of the first pipe 1, and when the second sleeve 7 is embedded on the peripheral wall of the second pipe 5, the peripheral wall of the second sleeve 7 is flush with the peripheral wall of the second pipe 5.

As shown in fig. 1, the inner circumferential wall of the first sleeve 3 is further provided with a plurality of first ribs 13 protruding inwards, so that the connection strength between the first sleeve 3 and the first pipe 1 can be improved, and the tensile resistance between the first sleeve and the first pipe can be improved. Correspondingly, as shown in fig. 6, a plurality of second ribs 13 protruding inwards are further provided on the inner circumferential wall of the second sleeve 7, so that the connection strength between the second sleeve 7 and the second pipe 5 can be improved, and the tensile resistance of the two can be improved.

It should be noted that the length, diameter, thickness and other dimensions of the first sleeve 3 and the second sleeve 7 should be adjusted according to the strength, pipe diameter, thickness and other dimensions of the corresponding pipes, and therefore, the dimensions are not particularly limited herein.

As shown in fig. 4, the snap ring 9 includes a main body portion 10 and an elastic portion 11, the main body portion 10 is provided with a notch, the elastic portion 11 is provided at the notch and connected to the main body portion 10, that is, the snap ring 9 is composed of the main body portion 10 and the elastic portion 11, which can be regarded as that the main body portion 10 is annular, then the notch is provided on the main body portion 10, and the elastic portion 11 is refilled into the notch and connected to the main body portion 10, so that an annular snap ring 9 can still be spliced. The elastic portion 11 has elasticity, and when the snap ring 9 is expanded, the elastic portion 11 can be elastically deformed so that the circumferential dimension of the snap ring 9 becomes large.

In practical applications, the main body 10 is a metal part, and the elastic part 11 is a rubber part. The main body 10 and the elastic part 11 are detachably connected, thereby facilitating the subsequent disassembly and replacement. For example, the main body 10 and the elastic part 11 are provided with mounting through holes, and the pin can be inserted into the mounting through holes of the main body and the elastic part to realize the detachable connection, which is simple and easy to use.

Further, the main body 10 may have a plurality of notches, and each notch has an elastic portion 11, so that the snap ring 9 may be deformed more easily, and the snap ring 9 may be conveniently opened for installation.

The use process of this device is shown in fig. 5 and fig. 6, before inserting first tubular product 1 that inlays in advance and have first sleeve 3 into second tubular product 5 that inlays in advance and have second sleeve 7, need earlier put into the second draw-in groove 8 of second sleeve 7 snap ring 9 and sealing washer 12, then insert the socket end 2 of first tubular product 1 into the female end 6 of second tubular product 5, in this process, snap ring 9 and sealing washer 12 can be strutted, until first draw-in groove 4 and second draw-in groove 8 are just right, the two converge to enclose and limit complete ring groove this moment, snap ring 9 and sealing washer 12 then retract the card and establish in the draw-in groove, accomplish the connection of two tubular products. The connecting mode is simple and quick, firm in connection, compact in structure, convenient to construct and operate and high in practicability.

The sealing washer 12 that sets up can play sealed effect, prevents to appear leaking the condition, and the cooperation of snap ring 9 and draw-in groove then can be spacing to the axial of first tubular product 1 and second tubular product 5, prevents that the two from breaking away from the cooperation.
