Description
Technical Field
[0001] This utility model belongs to the field of PE pipe technology, and in particular relates to a PE pipe that is easy to assemble. Background Technology
[0002] PE pipes (polyethylene plastic pipes) are widely used in building water supply and drainage, municipal gas transmission, agricultural irrigation, and industrial fluid transmission due to their corrosion resistance, high pressure resistance, and low cost. With the development of urbanization and infrastructure projects, the demand for PE pipe installation is increasing, and the convenience and reliability of their connection methods directly affect project efficiency and system stability.
[0003] Currently, PE pipes are typically connected using direct heat fusion or heat fusion flanges (where the flanges are welded together and then secured with bolts). However, these methods have the following drawbacks in practical use:
[0004] First, direct heat fusion connection or heat fusion flange connection requires a special heat fusion machine or electrofusion welding machine, which has high equipment costs and a high technical threshold. Operators need to master the welding parameters, and novices are prone to over-melting or poor connection of pipes due to improper temperature control. Second, with direct heat fusion connection or heat fusion flange connection, the pipe angle is fixed. When encountering obstacles such as corners, beams and columns, 90°, 45° prefabricated elbows are required.
[0005] Therefore, it is essential to invent a PE pipe that is easy to assemble. Utility Model Content
[0006] To address the above problems, this utility model proposes a PE pipe that is easy to assemble. The technical solution used is as follows:
[0007] A PE pipe that is easy to assemble includes a first pipe body, a second pipe body, a connector, a corrugated pipe, a positioning post, a positioning groove, and a positioning frame. The first pipe body and the second pipe body have the same internal structural shape, and a connector is slidably installed at one end of each of the first and second pipe bodies, wherein a corrugated pipe is fixed between the connectors. Positioning grooves are formed along a straight line on both the first and second pipe bodies. A positioning post is fixed to each connector by thread engagement, wherein one end of the positioning post is slidably installed inside the corresponding positioning groove. A positioning frame is rotatably installed between the connectors.
[0008] Furthermore, the connector includes a mounting ring, an inner tube, an outer tube, and a sealing ring. A corrugated pipe is fixed to the outer side of one end of the mounting ring, and the other end of the mounting ring is integrally formed with an inner tube and an outer tube, wherein the inner tube is disposed inside the outer tube. The outer side of the inner tube is fitted against the inner wall of the first tube body or the second tube body, and the inner side of the outer tube is fitted against the outer side of the first tube body or the second tube body. A positioning post passes through the outer tube by thread engagement, and a positioning bracket is rotatably mounted on the outer side of the outer tube. Sealing rings are fixed to both the inner wall of the outer tube and the outer side of the inner tube. This arrangement facilitates assembly onto the first tube body or the second tube body.
[0009] Furthermore, the positioning frame includes a first rocker arm, a stud, a second rocker arm, and a nut. One end of the first rocker arm is rotatably connected to one of the connectors, and one end of the second rocker arm is rotatably connected to the other connector. A stud is welded to the first rocker arm, and the stud is rotatably connected to the second rocker arm. A nut is threadedly fixed to the stud. This arrangement allows the bending angle of the bellows to be fixed after adjustment.
[0010] Furthermore, several cutting lines are engraved on the corresponding positions of the outer surfaces of the first and second tubes. This arrangement makes it convenient for workers to cut the first or second tube according to the position of the cutting lines, so that the positioning pin on the connector can cooperate with the corresponding positioning groove.
[0011] Furthermore, several reinforcing meshes are fixed inside the first and second pipe bodies, with each reinforcing mesh set on one side of a corresponding positioning groove. The reinforcing meshes are all made of metal wire mesh structure, and the width of the reinforcing mesh is greater than the diameter of the positioning groove. This arrangement can improve the structural strength of the first and second pipe bodies and prevent the first and second pipe bodies from cracking at the positioning groove position.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The design of this utility model allows the connector to be slidably assembled onto the corresponding first and second pipe bodies. Then, the connector and the first or second pipe body are fixed by the cooperation of the positioning post and the positioning groove. Compared with the traditional welding method, this method has lower technical content and can be disassembled after assembly. Secondly, the corrugated pipe design allows the angle between the first and second pipe bodies to change, thus enabling the assembled PE pipe to adapt to complex pipeline layouts. At the same time, the positioning bracket design can fix the bending angle of the corrugated pipe. Attached Figure Description

[0025] Specifically, the connector 3 includes a mounting ring 31, an inner tube 32, an outer tube 33, and a sealing ring 34. A corrugated pipe 4 is fixed to the outer side of one end of the mounting ring 31, and the other end of the mounting ring 31 is integrally formed with an inner tube 32 and an outer tube 33, wherein the inner tube 32 is disposed inside the outer tube 33; the outer side of the inner tube 32 is fitted against the inner wall of the first pipe body 1 or the second pipe body 2, and the inner side of the outer tube 33 is fitted against the outer side of the first pipe body 1 or the second pipe body 2; the outer tube 33 is threaded through... The outer tube 33 has a positioning post 5 and a positioning bracket 7 is rotatably mounted on the outer side of the outer tube 33; both the inner wall of the outer tube 33 and the outer side of the inner tube 32 are fixed with sealing rings 34. When it is necessary to assemble the first tube 1 and the second tube 2, the inner tube 32 of the connector 3 can be set on the inner side of the first tube 1 or the second tube 2, and the outer tube 33 of the connector 3 can be fixed on the outer side of the first tube 1 or the second tube 2, thereby sealing the connector 3 with the first tube 1 or the second tube 2 through the sealing ring.
