Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a steel wire mesh skeleton plastic pipe connection structure. Background Art

[0002] The wall thickness of the steel mesh skeleton plastic composite pipe under the same pressure level is smaller than that of the ordinary plastic composite pipe, making the pipe size lighter and more compact. Compared with the pipe body made of PE plastic alone, the steel mesh skeleton plastic composite pipe has better pressure resistance, which can further improve the service life of the pipe, reduce the cost of later pipeline maintenance, and reduce the frequency of later maintenance. Pipe connection refers to connecting two pipes to each other. For plastic pipes, electric heat-melting pipe fittings are often used. Electric heat-melting pipe fittings use electric heating elements embedded in the inner surface of the pipe fittings. A connection method in which high temperature is generated when the parts are energized to weld the contact surfaces into a whole. The electric heating element here usually adopts electric heating wire. Although the hot melt connection method is widely used, in some construction processes, the transmission line needs to be adjusted accordingly, so it is necessary to disassemble the connected multiple pipes again. The hot melt connection method is not convenient for disassembling the connected pipes. The connecting pipe needs to be cut off and reconnected with a new connecting pipe. Such repeated operations are likely to cause certain damage to the pipeline, affecting the normal use of the pipeline. In addition, the operation is very troublesome, the applicability is poor, and it will also increase the waste rate of pipe fittings. Utility Model Content

[0018] In this embodiment, when two groups of plastic pipe bodies 1 need to be connected, the fastening plate 2 of one group of plastic pipe bodies 1 is firstly abutted against the opening of the sealing groove 10 opened in the other group of plastic pipe bodies 1, and the fastening plate 2 is pushed to rotate by the push plate 6, and then the fastening plate 2 can be smoothly embedded in the sealing groove 10 through the threaded structure, and then the other group of plastic pipe bodies 1 can be synchronously moved under the drive of the corresponding main fixing ring 4. In the process of the two groups of plastic pipe bodies 1 approaching each other, the embedding groove opened in one group of plastic pipe bodies 1 will be gradually embedded by the embedding ring 11 of the other group of plastic pipe bodies 1. Therefore, when the fastening plate 2 is fully embedded in the corresponding sealing groove 10, the embedding ring 11 will also be fully embedded in the corresponding embedding groove at the same time, that is, the two groups are realized. The quick loading and unloading of the plastic pipe body 1 can also help enhance the sealing of the connection between the two groups of plastic pipe bodies 1. At the same time, during the assembly process of the two groups of plastic pipe bodies 1, the main fixing ring 4 and the auxiliary fixing ring 9 gradually approaching the two ends of the fastening plate 2 will squeeze the sealing layer 7 accordingly, so that the squeezed and deformed sealing layer 7 will fully abut the outer side surface of the connection between the two groups of plastic pipe bodies 1, thereby further enhancing the sealing of the connection between the two groups of plastic pipe bodies 1. After that, the fastening screw 3 is rotated, and the fastening screw 3 pushes the threaded fastening block 5 to move, and the fastening block 5 abuts against the end face of the fastening plate 2 through the fastening layer, and the protrusion 12 set on the end face of the fastening plate 2 will squeeze the fastening layer, thereby enhancing the fixing effect between the fastening block 5 and the fastening plate 2.

[0022] In this embodiment, as Figure 1 , the sealing ring 8 is made of soft rubber material, and the inner and outer sides of the sealing ring 8 are respectively adapted to the sizes of the fitting ring 11 and the fitting groove. Therefore, the sealing performance of the connection between the two groups of plastic pipe bodies 1 can be further enhanced with the cooperation of the sealing ring 8.

Moreover, the sizes of the receiving groove and the fastening block 5 are adapted to each other, and a fastening layer is fixedly connected to the surface of the fastening block 5.
