Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene plastic composite pipes, in particular to a mesh steel belt polyethylene plastic composite pipe. Background Art

[0002] The main component of polyethylene plastic is polyethylene. Its raw material ethylene mainly comes from petroleum cracking and is a petrochemical product. Polyethylene (PE) is one of the five major synthetic resins and is the variety with the largest production capacity and the largest import volume among my country's synthetic resins. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE). It has excellent corrosion resistance and electrical insulation (especially high-frequency insulation). It can be chlorinated, irradiated, and reinforced with glass fiber. The melting point, rigidity, hardness and strength of low-pressure polyethylene are high, the water absorption is small, and it has good electrical properties and radiation resistance. The mesh steel belt polyethylene composite pipe is a composite pipe with a mesh pipe welded with cold-rolled steel strips as the reinforcement skeleton and composite thermoplastics. Due to the introduction of the reinforcement skeleton, the compressive strength of the pipe is significantly improved. The selection of different types and grades of thermoplastics can produce composite pipes for different purposes.

DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1 As shown, a mesh steel belt polyethylene plastic composite pipe includes two polyethylene plastic composite pipes 1, the right ends of the outer surfaces of the left parts of the two polyethylene plastic composite pipes 1 are fixedly connected with a connecting mechanism 2, the outer surface of the right part of the polyethylene plastic composite pipe 1 near the left end is fixedly connected with a sealing mechanism 3, and the left side surface of the sealing mechanism 3 is fixedly connected with an anti-slip gasket 7.

[0028] It should be noted that the two polyethylene plastic composite pipes 1 can be connected by the connection mechanism 2 and the sealing structure, and the anti-slip gasket 7 is used to make the connection achieve a certain sealing performance, thereby improving the practicality to a certain extent.

[0029] like Figure 3 As shown, a steel belt 4 is fixedly connected to the middle of the outer surface of the two polyethylene plastic composite pipes 1, a mesh layer 5 is fixedly connected to the inner wall of the two polyethylene plastic composite pipes 1, and an inner layer pipe 6 is fixedly connected to the inner wall of the mesh layer 5.

[0030] It should be noted that a steel belt 4 is provided at regular intervals on the outer surface of the polyethylene plastic composite pipe 1. The steel belt 4 is made of steel alloy and has good hardness, which improves the practicality of the polyethylene plastic composite pipe 1 to a certain extent. At the same time, a middle mesh layer 5 and an innermost inner layer pipe 6 are provided inside the polyethylene plastic composite pipe 1. The mesh layer 5 effectively improves the strength of the composite pipe, and anti-corrosion coating is coated on the outer surface of the polyethylene plastic composite pipe 1 and the inner surface of the inner layer pipe 6, which protects the polyethylene plastic composite pipe 1 to a greater extent.

[0031] like Figure 3-Figure 5 As shown, the connecting mechanism 2 includes a connecting ring 20, the inner wall of which is fixedly connected to the right end of the outer surface of the left part of the polyethylene plastic composite pipe 1, two connecting plates 21 are fixedly connected to the outer surfaces of the upper and lower sides of the connecting ring 20, and two connecting plates 23 are fixedly connected to the outer surfaces of the upper and lower sides of the connecting ring 20 clockwise, and the sealing mechanism 3 includes a connecting ring 30, the inner wall of the connecting ring 30 is fixedly connected to the outer surface of the right part of the polyethylene plastic composite pipe 1 near the left end, two connecting blocks 23 are fixedly connected to the outer surfaces of the front and rear sides of the connecting ring 30, two connecting blocks 31 are fixedly connected to the outer surfaces of the front and rear sides of the connecting ring 20 counterclockwise, and the left side surface of the connecting ring 30 is fixedly connected to the right side surface of the anti-slip gasket 7.

[0032] It should be noted that, first, the two ends of the two polyethylene plastic composite pipes 1 are aligned with each other, so that the polyethylene plastic composite pipe 1 on the right side slides into the connecting ring 1 20, and the connecting plate 1 21 should be located counterclockwise of the connecting block 1 31, and the connecting plate 2 23 should be located between the connecting block 1 31 and the connecting block 2 33, and then the polyethylene plastic composite pipe 1 on the left side is rotated clockwise, so that the sliding rod 1 22 slides into the sliding hole 2 32, and the sliding rod 24 also slides into the sliding hole 34, and then the rocker 35 is rotated clockwise, thereby driving the threaded rod 37 to rotate clockwise, and at this time the limit plate 38 should just rest against the inner wall of the connecting block 2 33 On the left side, and the sliding rod three 39 is inside the partition between the inner wall of the connecting block two 33 and the sliding hole three 34. Since the threaded sleeve 36 and the threaded rod 37 are threadedly connected to each other, the threaded sleeve 36 will not rotate but move to the right, so that the sliding rod three 39 slides into the sliding hole one 25, thereby fixing the connecting ring one 20 and the connecting ring two 30, and then connecting the two polyethylene plastic composite pipes 1. An anti-skid gasket 7 is provided on the surface of the connecting ring two 30. When the connecting ring one 20 and the connecting ring two 30 are fixed, the anti-skid gasket 7 will be squeezed, thereby ensuring a stable connection and further achieving a sealing effect.

[0033] like Figure 5 , Figure 6 As shown, a threaded rod 37 is rotatably connected to the right side of the inner wall of the connecting block 2 33, and the left end of the threaded rod 37 passes through the left end of the connecting block 2 33 and is fixedly connected to a rocker 35, and a threaded sleeve 36 is threadedly connected to the outer surface of the threaded rod 37, and a limit plate 38 is fixedly connected to the upper side of the outer surface of the threaded sleeve 36, and a slide rod 39 is fixedly connected to the right side of the upper end of the limit plate 38.

[0034] It should be noted that, by rotating the rocker 35 clockwise, the threaded rod 37 is driven to rotate clockwise. At this time, the limit plate 38 should just rest against the left side of the inner wall of the connecting block 2 33, and the sliding rod 39 is inside the partition between the inner wall of the connecting block 2 33 and the sliding hole 34. Since the threaded sleeve 36 and the threaded rod 37 are threadedly connected to each other, the threaded sleeve 36 will not rotate but move to the right, so that the sliding rod 39 slides into the sliding hole 1 25, thereby fixing the connecting ring 1 20 and the connecting ring 2 30, and then connecting the two polyethylene plastic composite pipes 1.

[0035] like Figure 4-Figure 6As shown, a sliding hole three 34 is provided in the middle of the two connecting blocks two 33, and a sliding rod two 24 is fixedly connected to the left side of the two connecting plates two 23, and the outer surface of the sliding rod two 24 is slidably connected to the inner wall of the sliding hole three 34, and a sliding hole one 25 is provided at the end of the sliding rod two 24 away from the connecting plate two 23, and the right end of the sliding rod three 39 passes through the right side of the inner wall of the connecting block two 33 and is slidably connected to the inner wall of the sliding hole one 25, and the front side surfaces of the two connecting plates two 23 are fixedly connected to the sliding rod one 22, and a sliding hole two 32 is provided in the middle of the connecting block one 31, and the inner wall of the sliding hole two 32 is slidably connected to the outer surface of the sliding rod one 22.

[0036] It should be noted that, according to the multiple sliding hole and sliding rod structures, the connecting block and the connecting plate can be smoothly connected together, thereby connecting the two polyethylene plastic composite pipes 1 to achieve a stable connection effect.

[0037] The working principle of the utility model is as follows: first, align the two ends of the two polyethylene plastic composite pipes 1 with each other, so that the polyethylene plastic composite pipe 1 on the right side slides into the connecting ring 1 20, and at the same time, the connecting plate 1 21 should be located counterclockwise of the connecting block 1 31, and the connecting plate 23 should be located between the connecting block 1 31 and the connecting block 2 33, and then rotate the polyethylene plastic composite pipe 1 on the left side clockwise, so that the sliding rod 1 22 slides into the sliding hole 2 32, and the sliding rod 24 also slides into the sliding hole 34, and then rotate the rocker 35 clockwise, thereby driving the threaded rod 37 to rotate clockwise, at this time, the limit plate 38 should just rest against the left side of the inner wall of the connecting block 2 33, and the sliding rod 3 39 is inside the partition between the inner wall of the connecting block 2 33 and the sliding hole 34, because the threaded sleeve 36 and the threaded rod 37 are threadedly connected to each other, so that the threaded sleeve 36 will not rotate but move to the right, so that the sliding rod 39 slides into the sliding hole 1 25 In the process, the connection ring 1 20 and the connection ring 2 30 are fixed, and then the two polyethylene plastic composite pipes 1 are connected. An anti-skid gasket 7 is arranged on the surface of the connection ring 2 30. When the connection ring 1 20 and the connection ring 2 30 are fixed, the anti-skid gasket 7 will be squeezed. While ensuring a stable connection, the sealing effect is further achieved. A steel belt 4 is arranged on the outer surface of the polyethylene plastic composite pipe 1 at regular intervals. The steel belt 4 is made of steel alloy and has good hardness, which improves the practicality of the polyethylene plastic composite pipe 1 to a certain extent. At the same time, a middle mesh layer 5 and an innermost inner layer pipe 6 are arranged inside the polyethylene plastic composite pipe 1 respectively. The mesh layer 5 is effectively used to improve the firmness of the composite pipe, and the outer surface of the polyethylene plastic composite pipe 1 and the inner surface of the inner layer pipe 6 are coated with anti-corrosion coatings, which protect the polyethylene plastic composite pipe 1 to a greater extent.
