Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a plastic composite pipe which is easy to connect. Background Art

[0002] The steel wire mesh skeleton plastic composite pipe is a new type of improved steel skeleton plastic composite pipe. This new type of pipe is made of high-strength plasticized steel wire mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. It uses high-density polyethylene (HDPE) as the matrix and uses high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has an excellent composite effect. Because the high-strength steel wire reinforcement is coated in continuous thermoplastic plastic, this composite pipe overcomes the shortcomings of steel pipes and plastic pipes, while maintaining their respective advantages. Pipeline construction usually involves connecting multiple shorter pipes into a longer pipe. Before connecting, the ends of the two pipes need to be aligned through the docking kit for plastic composite pipes, and then the next step of connection operation is carried out.

[0003] For example, the Chinese patent authorization announcement number: CN 217519457 U discloses a butt joint kit for plastic composite pipes, which uses an electric fusion pipe sleeve placed in a flange sleeve to form a butt joint kit for connecting the ends of the plastic composite pipe, and utilizes the hot-melt performance of the electric fusion pipe sleeve to hot-melt and bond the plastic composite pipe.

[0004] Therefore, most of the existing plastic composite pipes use a docking kit to connect two plastic composite pipes, which requires matching corresponding docking kits, is inconvenient for on-site construction, and makes the use cost of the plastic composite pipe high. Utility Model Content

[0023] In a preferred embodiment, the docking plate 2 and the docking groove 3 match each other, and a card slot 11 is provided on the side wall of the docking plate 2, and the card slot 11 matches the card block 4. The docking plate 2 can enter the docking groove 3 to achieve the initial positioning of the two composite pipe bodies 1, and the card block 4 is inserted into the card slot 11 to achieve the limited fixation of the docking plate 2.

[0024] In a preferred embodiment, the slider 6 is arranged through the slide groove 7, and the connection between the rotating shaft 10 and the composite pipe body 1 is provided with an external thread. The side wall of the composite pipe body 1 is provided with an internal thread hole matching the external thread. Before the docking plate 2 is inserted into the plug-in groove 3 or the two composite pipe bodies 1 are docked, the rotating shaft 10 is used to drive the winding wheel 9 to rotate. When the winding wheel 9 rotates, the pull rope 8 can be wound up, and the pull rope 8 is used to pull the slider 6 and the block 4 to move, so that the block 4 compresses the spring 5, and the block 4 moves away from the slot 11 to release the limit of the docking plate 2.

[0025] In a preferred embodiment, a knob 12 is fixedly provided at one end of the rotating shaft 10 away from the composite pipe body 1 , and the two docking grooves 3 are symmetrically arranged on both sides of the rotating shaft 10 . The arrangement of the knob 12 facilitates the rotation drive of the rotating shaft 10 .

[0026] In a preferred embodiment, a storage groove 13 is opened on the side wall of one end of the composite tube body 1, one end of the docking plate 2 is rotatably set at one end of the storage groove 13, and a rubber damping block 14 is set on the inner wall of the storage groove 13.

The arrangement of the mounting groove 15, the sealing gasket 16 and the slot can achieve a better sealing effect after the two composite pipe bodies 1 are docked.

[0028] The working principle of the utility model is:

[0029] When carrying, the docking plate 2 on each composite tube body 1 is rotated and stored in the storage groove 13. After the docking plate 2 is stored in the storage groove 13, the outer wall of the docking plate 2 contacts the rubber damping block 14 on the inner wall of the storage groove 13. The rubber damping block 14 can play a certain damping role on the docking plate 2 to prevent the docking plate 2 from automatically sliding out of the storage groove 13. The storage of the docking plate 2 can prevent the docking plate 2 from being exposed to the outside and damaged during the carrying process; and when the two composite tube bodies 1 are docked, the docking plate 2 is removed from the storage groove 13. The butt joint plate 2 is taken out from the receiving groove 13, and the butt joint plate 2 is inserted into the butt joint groove 3. When the butt joint plate 2 is inserted to the innermost end of the butt joint groove 3, the rotating shaft 10 is rotated by the knob 12, and the rotating shaft 10 drives the winding wheel 9 to rotate, and the winding wheel 9 loosens the two draw ropes 8. After the slider 6 loses the limiting effect of the draw rope 8, the card block 4 is rebounded into the card groove 11 under the action of the spring 5, so as to realize the limiting fixation of the butt joint plate 2. After the butt joint is completed, the sealing gasket 16 is inserted into the slot to realize the sealing of the two composite pipe bodies 1;

[0030] When disassembling the two joined composite pipe bodies 1, the knob 12 drives the rotating shaft 10 and the winding wheel 9 to rotate in opposite directions, and the winding wheel 9 winds up the pull rope 8, so that the pull rope 8 drives the slider 6 and the block 4 to move, so that the block 4 is moved out of the slot 11, and the limit on the docking plate 2 is released. Then, the docking plate 2 can be pulled out of the docking slot 3, which facilitates the disassembly of the two composite pipe bodies 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
