[0002] AGR is a new type of material made by chemical copolymerization of ultra-fine acrylic elastomer fully integrated into polyvinyl chloride molecules. Its Chinese name is acrylic acid copolymer polyvinyl chloride. AGR pipes are used as urban water supply networks and water supply pipes in buildings. It is one of the preferred water supply pipes that is safe, hygienic, stable, reliable, has a long service life, is resistant to low temperatures and impacts. Traditional AGR pipe interfaces often use the socket method for docking. When connecting, a rubber sealing ring must be selected and inserted into the connection port. The sealing requirements are met after the spigot and the socket are fully docked.

[0003] According to the utility model with Chinese patent application number 202221739906.1, an AGR pipe with an interface having a connecting sealing and anti-falling structure has the advantages of tight connection and not easy to fall off when in use. However, it is inconvenient to take anti-falling reinforcement measures on the ring body when using the AGR pipe with an interface having a connecting sealing and anti-falling structure, which makes it easy to fall off during use. Therefore, it is necessary to propose an AGR pipe with an interface having a fixed anti-falling sealing structure to solve the above-mentioned problems. Utility Model Content

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The interface has an AGR pipeline with a fixed anti-detachment sealing structure. By setting a reinforcement structure, when in use, the connector is inserted into the interior of the reinforcement cylinder and the rotating sleeve is rotated.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In this embodiment, an AGR pipeline having an interface with a fixed anti-slip sealing structure comprises a reinforcement cylinder 1, a second pipeline 4 and a first pipeline 3 are respectively plugged and installed on the left and right sides of the reinforcement cylinder 1, a connector 12 is fixedly installed on the side corresponding to each other of the first pipeline 3 and the second pipeline 4, a rotating sleeve 2 is movably installed on the outside of the reinforcement cylinder 1, an annular plate 13 is arranged inside the reinforcement cylinder 1 and the rotating sleeve 2, and a reinforcement structure 10 is movably installed inside the reinforcement cylinder 1;

[0021] The reinforcement structure 10 includes a limiting slide bar 101. The front side of the annular plate 13 is provided with a limiting slide bar 101. The limiting slide bar 101 is internally slidably installed with a limiting slide rod 102 at both ends fixedly connected with positioning columns 105. One end of the positioning column 105 is fixedly connected with a rubber positioning block 106. A positioning plate 103 is fixedly installed on one side of the annular plate 13 fixedly set on the reinforcement tube 1. A limiting slideway 104 is arranged inside the positioning plate 103. The limiting slideway 104 is internally slidably installed with a positioning column 105.

[0022] When the reinforcing structure 10 is used, the connecting head 12 is inserted into the reinforcing tube 1 and the rotating sleeve 2 is rotated. The rotating sleeve 2 will drive the annular plate 13 to rotate. When the annular plate 13 rotates, the position of the limiting slide bar 101 will change. At this time, the position of the limiting slide bar 102 does not change with the position of the annular plate 13. At this time, the inner wall of the limiting slide bar 101 will push the limiting slide bar 102 to move, and further make the limiting slide bar 102 push the positioning column 105 and the rubber positioning block 106 to slide in the interior of the positioning plate 103. The positioning column 105 and the rubber positioning block 106 gradually approach the outside of the connecting head 12 at the same time until the positioning column 105 and the rubber positioning block 106 are inserted into the interior of the positioning hole 7, so as to achieve the purpose of positioning the connecting head 12 and the first pipe 3, and finally make the reinforcing tube 1 reinforce the connection between the two connected first pipes 3 and the second pipes 4, effectively prevent them from falling off, and increase the firmness of the connection.

[0023] By setting the first sealing ring 5, the first sealing ring 5 and the second sealing ring 6 are set outside away from the center of the reinforcement tube 1, so as to further seal the gap between the connecting head 12 and the reinforcement tube 1 to avoid water leakage after the connection is used, and a third sealing ring 11 is set to further improve the sealing performance when the reinforcement tube 1 is connected with the first pipe 3 and the second pipe 4, so that the sealing performance of the connection between the first pipe 3 and the second pipe 4 and the reinforcement tube 1 is further improved.

[0024] In the production process of this ARG pipe, the main thing is to put the rubber ring inside the expanded mouth when the pipe is expanded. The rubber ring: the inner steel ring is covered with rubber, with strong elasticity and three waterproof backflow slots. This interface method is safe and not easy to slip out, has good sealing and does not leak, and solves the problems of slipping, flipping and leakage caused by the old rubber ring connection.

[0025] When implementing, follow these steps:

[0026] 1) First, insert the connector 12 into the reinforcement tube 1;

[0027] 2) Then rotate the rotating sleeve 2, which will drive the annular plate 13 to rotate;

[0028] 3) The inner wall of the limiting slide bar 101 pushes the limiting slide bar 102 to move, and the limiting slide bar 102 further pushes the positioning column 105 and the rubber positioning block 106 to slide inside the positioning plate 103;

[0029] 4) Finally, the positioning column 105 and the rubber positioning block 106 are inserted into the interior of the positioning hole 7 to achieve the purpose of positioning the connector 12 and the first pipe 3.

[0030] In summary, the interface has an AGR pipeline with a fixed anti-detachment sealing structure. By setting a reinforcement structure 10, when in use, by inserting the connector 12 into the interior of the reinforcement cylinder 1 and rotating the rotating sleeve 2, the rotating sleeve 2 will drive the annular plate 13 to rotate. When the annular plate 13 rotates, the position of the limiting slide bar 101 will be driven to change. At this time, the position of the limiting slide bar 102 does not change with the position of the annular plate 13. At this time, the inner wall of the limiting slide bar 101 will push the limiting slide bar 102 to move, and further make the limiting slide bar 102 push the positioning column 105 and the rubber positioning block 106 to slide inside the positioning plate 103. The positioning column 105 and the rubber positioning block 106 gradually approach the outside of the connector 12 at the same time, until the positioning column 105 and the rubber positioning block 106 are inserted into the interior of the positioning hole 7, so as to achieve the purpose of positioning the connector 12 and the first pipe 3, and finally make the reinforcement cylinder 1 reinforce the connection between the two connected first pipes 3 and the second pipe 4, effectively prevent falling off, and increase the firmness of the connection.

[0031] Furthermore, by providing a first sealing ring 5, the first sealing ring 5 and the second sealing ring 6 are provided on the outside away from the center of the reinforcement tube 1, so that the gap between the connecting head 12 and the reinforcement tube 1 can be further sealed to avoid water leakage after the connection is used, and a third sealing ring 11 is provided to further improve the sealing performance when the reinforcement tube 1 is connected to the first pipe 3 and the second pipe 4, so that the sealing performance of the connection between the first pipe 3 and the second pipe 4 and the reinforcement tube 1 is further improved.
