They are mainly used as piping for water supply systems, drainage, ventilation and sewage in residential buildings, underground drainage systems, rainwater pipes, and electrical wiring installation.

[0003] Some composite plastic pipes are made of a single material and have a relatively simple structure, which makes them prone to breakage when subjected to external impacts due to environmental factors during use. In addition, some composite plastic pipes are mainly connected by heat fusion, which requires the entire pipe to be replaced when it breaks, making the replacement process cumbersome. Therefore, they do not meet the current needs. In response, we have proposed a new type of composite plastic pipe. Utility Model Content

[0008] Preferably, both the upper and lower drive slots are fixedly connected to a drive rod extending through to the outside of the connecting pipe, and the drive rod is fixedly connected to a limiting plate that is slidably connected to the drive slot on its outer surface near the upper end inside the drive slot.

[0009] Preferably, each of the two drive rods has a connecting plate fixedly connected to one end of each other, and the two ends of the connecting plate are slidably connected to the inside of the strip groove. Each of the two connecting plates has a spring fixedly connected to one side of the limiting plate at the other end of each other, and the spring is wrapped around the outer surface of the drive rod.

[0010] Preferably, both ends of the two connecting plates that are far apart from each other are fixedly connected to limit blocks, and the end of the limit block that is far away from the connecting plate extends movably through into the interior of the docking groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 The present invention provides an embodiment of a composite plastic pipe, comprising a composite pipe body 1 and a connecting pipe 2. The composite pipe body 1 includes a main pipe body 101, a support ring 102 fixedly provided on the outer surface of the main pipe body 101, a plurality of support bars 103 fixedly connected at equal intervals on the outer surface of the support ring 102, and an outer protective ring 104 fixedly connected on the outer surface of the support bars 103. Both ends of the connecting pipe 2 are provided with mating grooves 201, and sealing gaskets 8 are fixedly connected inside the mating grooves 201 on both sides. One end of the composite pipe body 1 is detachably connected to the mating groove 201 and is in close contact with the sealing gasket 8.

[0022] The support bar 103 is arranged along the length of the main body 101. The support ring 102 on the outer surface of the main body 101 and the support bar 103, together with the outer protective ring 104, can improve the impact resistance of the main body 101.

[0023] The connecting pipe 2 has drive grooves 202 at both the top and bottom. On the side of the two drive grooves 202 that are close to each other, there is a strip groove 203 inside the connecting pipe 2. The strip groove 203 is connected to the drive groove 202 and its two ends extend to the bottom of the docking groove 201. The drive rod 3 that extends through to the outside of the connecting pipe 2 is fixedly connected inside the upper and lower drive grooves 202. The outer surface of the drive rod 3 inside the drive groove 202 near the upper end is fixedly connected to a limiting plate 4 that is slidably connected to the drive groove 202. The ends of the two drive rods 3 that are close to each other are fixedly connected to a connecting plate 5, and the two ends of the connecting plate 5 are slidably connected to the inside of the strip groove 203. The ends of the two connecting plates 5 that are far apart from each other are fixedly connected to one side of the limiting plate 4 and the spring 6 is wrapped around the outer surface of the drive rod 3.

[0024] By pressing the two drive rods 3 on the upper and lower parts of the connecting tube 2, the upper and lower drive rods 3 drive the limiting plate 4 to slide along the drive groove 202 and compress the spring 6, thereby driving the upper and lower connecting plates 5 to slide closer along the strip groove 203.

[0025] Limiting blocks 7 are fixedly connected to both ends of the two connecting plates 5 on the side away from each other. The end of the limiting block 7 away from the connecting plate 5 extends through and into the interior of the docking groove 201. Symmetrical limiting grooves 10101 are opened on the upper and lower sides of the inner wall of one end of the main body 101. The end of the limiting block 7 extending through and into the interior of the docking groove 201 is inserted into the corresponding limiting groove 10101.

[0026] By bringing the upper and lower connecting plates 5 closer together, the limiting blocks 7 at both ends of the connecting plates 5 are moved and stored inside the strip groove 203. Then, the adjacent ends of the two composite tubes 1 can be inserted into the docking grooves 201 on both sides of the connecting pipe 2. Then, the pressure on the upper and lower drive rods 3 is released, so that the spring 6 releases its elastic force and drives the connecting plates 5 to reset. This allows the limiting blocks 7 at both ends of the connecting plates 5 to extend through into the docking groove 201 and be inserted into the limiting groove 10101 inside the main tube 101, thereby connecting the two composite tubes 1 through the connecting pipe 2.

[0027] When the composite plastic pipe is in use, the support ring 102 and support strip 103 on the outer surface of the main pipe 101, together with the outer protective ring 104, can improve the impact resistance of the main pipe 101, prevent it from breaking when it encounters external impact, and reduce the amount of material consumed in production. When it is necessary to connect two composite pipe bodies 1, by pressing the two drive rods 3 on the upper and lower parts of the connecting pipe 2, the upper and lower drive rods 3 drive the limiting plate 4 to slide along the drive groove 202 and compress the spring 6, thereby driving the upper and lower connecting plates 5 to slide closer along the strip groove 203, so that the limiting blocks 7 at both ends of the connecting plate 5 are... The two composite tubes 1 are moved and stored inside the strip groove 203. Then, the adjacent ends of the two composite tubes 1 can be inserted into the docking grooves 201 on both sides of the connecting tube 2 and contact the sealing gaskets 8 to increase the sealing of the connection. Then, the pressure on the upper and lower drive rods 3 is released, so that the spring 6 releases its elastic force and drives the connecting plate 5 to reset. Then, the limiting blocks 7 at both ends of the connecting plate 5 extend through into the docking groove 201 and are inserted into the limiting grooves 10101 inside the main tube 101, thereby connecting the two composite tubes 1 through the connecting tube 2, which facilitates the subsequent disassembly and replacement of the composite tubes 1 individually.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
