[0002] When laying rigid plastic pipes such as PVC and UPVC, the R-end pipes use the rubber ring socket method and the flat-end pipes use the adhesive method. The socket method has the advantages of convenience and high reliability and is the most widely used. However, the socket method connection requires that there is no axial relative movement between the pipes, otherwise it will cause the sealing ring to fail and leakage at the socket. Especially at the turning position of the pipe, the axial force generated by the pressure in the pipe is more likely to separate the socket. At present, cement pouring is mostly used to cast the joint as a whole, but this method incurs additional costs. In construction environments with poor road conditions, cement trucks are difficult to transport. The above problems restrict the installation speed of large-diameter plastic pipes and generate additional economic costs. Summary of the invention

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figures 1 to 9 It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] In the device of the present invention, one end of the pipe is processed into a female joint (1), and the other end is a circular pipe of equal diameter. The overall shape of the female joint (1) is a conical cylinder, and a circular arc groove (101) is processed inside the large diameter of the cone, and the groove is used to place the sealing ring (2);
[0026] The sealing ring (2) is composed of a rubber ring (21) and a rubber ring base (22). The rubber ring (21) is placed on the rubber ring base (22). An open groove is opened on the rubber ring base (22). It is a split structure, and can be placed in the arc groove (101) in a way of changing the diameter, and ensure that the axial position of the rubber ring (21) does not change during operation. In order to reduce the overall rigidity of the rubber ring base (22), it is designed in the form of multiple supporting blocks (221) connected in series, which reduces the overall rigidity and is easy to place, and makes the force on the rubber ring (21) more uniform.
[0027] The slip (3) is a multi-petal conical cylinder with a notch (304) and is provided with a latching tooth (302). The slip (3) is placed behind the sealing ring (2) and between the female connector (1) and the pipe (5). The latching tooth (302) matches the outer cylindrical surface of the pipe (5), and the conical surface (301) of the slip (3) matches the inner conical surface (102) of the female connector (1).
[0028] The slip-type tensioning mechanism (4) is a two-way type, and further comprises a clockwise hook (401), a rectangular groove (402), an external thread (403), a counterclockwise hook (404), a slip ring (405), and an opening and closing nut (406); wherein the slip ring (405) is arranged in the rectangular groove (402), the external thread (403) cooperates with the internal thread (407), and the clockwise hook (401) and the counterclockwise hook (404) simultaneously cooperate with the lifting shoulder (303) of the slip (3).
[0029] The slip tensioning mechanism (4) is a two-piece structure, which is arranged on the outer circumference of the pipe (5) and is used to tightly connect the female connector (1), the slip (3) and the pipe (5). When working, the clockwise hook (401) and the counterclockwise hook (404) are respectively hooked on the lifting shoulder (303) of the slip (3); the opening and closing nut (406) is matched with the external thread (403), and the upper end surface (408) of the opening and closing nut (406) is in contact with the lower end surface (103) of the female connector (1), and the opening and closing nut (406) is rotated to drive the slip (3) to produce axial downward movement, thereby making the slip (3) hold the pipe (5). After the female connector (1), the slip (3) and the pipe (5) are tightly connected, the slip tensioning mechanism (4) is removed to complete the connection of the pipe.
[0030] Working principle of the present invention:
[0031] The pipe is inserted into the female joint in a socket-and-spigot manner, and the sealing ring realizes the sealing function between the female joint and the pipe. The slip tensioning mechanism provides pre-tightening force for the slip, so that it tightly clamps the pipe and ensures the mutual connection between the female joint and the pipe.
