DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 5 As shown, a high-density polyethylene low-pressure steel belt reinforced water supply and drainage pipe includes a high-density polyethylene pipe 1, the front and rear ends of the high-density polyethylene pipe 1 are fixedly connected with a sealing ring 11, the outer wall of the high-density polyethylene pipe 1 is fixedly connected with a reinforcement mechanism 2, the left end of the high-density polyethylene pipe 1 is fixedly connected with a positioning mechanism 3, the inner wall of the high-density polyethylene pipe 1 is fixedly connected with an inner layer of polyethylene 4, the inner wall of the high-density polyethylene pipe 1 is fixedly connected with an anti-corrosion layer 14, the reinforcement mechanism 2 includes an outer layer of polyethylene 21, the inner wall of the outer layer of polyethylene 21 is fixedly connected to the outer wall of the high-density polyethylene pipe 1, the positioning mechanism 3 includes a positioning column 31, and the right end of the positioning column 31 is fixedly connected to the left end of the high-density polyethylene pipe 1.

[0027] The high-density polyethylene pipe 1 is reinforced by the reinforcement mechanism 2 to make it more durable and increase the service life of the high-density polyethylene pipe 1. Subsequently, the two high-density polyethylene pipes 1 are quickly positioned by the positioning mechanism 3 so that the two high-density polyethylene pipes 1 can be quickly connected to reduce working time.

[0028] like Figure 3 , Figure 5 As shown, the top of the longitudinal section of the outer polyethylene layer 21 is corrugated, and the inner cavity of the outer polyethylene layer 21 is in a rectangular array and fixedly connected with a low-pressure steel belt 22. The longitudinal section of the low-pressure steel belt 22 is a hollow circular ring, and the inner wall of the low-pressure steel belt 22 is fixedly connected to the outer wall of the high-density polyethylene tube 1.

[0029] The high-density polyethylene pipe 1 is reinforced by the low-pressure steel belt 22 fixedly connected to the inner wall of the protrusion of the outer polyethylene layer 21, thereby increasing the rigidity of the high-density polyethylene pipe 1 and making the high-density polyethylene pipe 1 more durable.

[0030] like Figure 3 , Figure 5 As shown, the inner wall of the low-pressure steel belt 22 is fixedly connected to the limit plate 23, the inner wall of the limit plate 23 is fixedly connected to the outer wall of the high-density polyethylene tube 1, and the inner wall of the outer layer of polyethylene 21 is fixedly connected to the arc plate 24 in a rectangular array, and the inner wall of the arc plate 24 is fixedly connected to the outer wall of the high-density polyethylene tube 1.

[0031] The low-pressure steel belt 22 is limited by the limiting plate 23 so that the low-pressure steel belt 22 always keeps in contact with the inner wall of the outer polyethylene layer 21 , thus achieving a supporting effect. Meanwhile, the outer polyethylene layer 21 is supported by the arc plate 24 .

[0032] like Figure 2-Figure 4 As shown, the right end of the high-density polyethylene tube 1 is provided with limiting holes 12 in a circular array. The limiting holes 12 are circular in shape. The inner cavity of the limiting holes 12 is fixedly connected to the limiting columns 13. The limiting columns 13 are hollow cylindrical in shape. The positioning columns 31 are cylindrical in shape. A circular hole 32 is provided in the middle of the positioning columns 31. The diameter of the positioning columns 31 is smaller than the diameter of the limiting holes 12.

[0033] When two sections of high-density polyethylene pipes 1 need to be connected, the outer wall of the positioning column 31 is inserted into the inner wall of the limiting hole 12 so that the outer wall of the positioning column 31 is completely inserted into the inner wall of the limiting hole 12 .

[0034] like Figure 5 As shown, a fixing column 33 is fixedly connected to the inner cavity of the circular hole 32, and the fixing column 33 has a cylindrical shape.

[0035] When the outer wall of the positioning column 31 is completely plugged into the inner wall of the limiting hole 12, the outer wall of the fixing column 33 is simultaneously plugged into the inner wall of the limiting column 13, thereby quickly positioning the two sections of high-density polyethylene pipes 1 for subsequent connection.

[0036] The working principle of the utility model is as follows: the high-density polyethylene pipe 1 is reinforced by the low-pressure steel belt 22, and at the same time, the low-pressure steel belt 22 is limited and supported by the limiting plate 23, so that the connection of the low-pressure steel belt 22 is more stable. When the high-density polyethylene pipe 1 is compressed, the low-pressure steel belt 22 absorbs the compressive force, so that the compressive force on the high-density polyethylene pipe 1 is reduced, thereby increasing the service life of the high-density polyethylene pipe 1. When the high-density polyethylene pipe 1 needs to be connected, the outer wall of the positioning column 31 is plugged into the inner wall of the limiting hole 12, so that the outer wall of the positioning column 31 is completely inserted into the inner wall of the limiting hole 12. It is connected to the inner wall of the limiting hole 12, and the outer wall of the fixing column 33 is plugged into the inner wall of the limiting column 13, thereby quickly positioning the two sections of high-density polyethylene pipes 1, which is convenient for subsequent connection and has the effect of quick positioning. In subsequent use, when water flows out of the high-density polyethylene pipe 1, the anti-corrosion layer 14 increases the anti-corrosion effect of the high-density polyethylene pipe 1, reduces the corrosion of the high-density polyethylene pipe 1, and increases the service life of the high-density polyethylene pipe 1, thereby increasing the service life of the high-density polyethylene pipe 1, thereby greatly improving the user experience.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
