Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pipe technology, specifically to a wear-resistant and pressure-resistant plastic pipe. Background Technology
[0002] Plastic pipes, as an important component of chemical building materials, are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. The main types include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, polypropylene PPR hot water pipes, and MPP pipes.
[0003] MMP pipes are widely used in underground cable laying projects. Due to the large number of cables, the diameter of MMP pipes is also large. During transportation by truck, the outer wall of large MMP pipes will rub against the truck bed, resulting in scratches on the outer wall of the MMP pipes and reducing their overall service life. Moreover, since the inside of the MMP pipes is not completely filled during cable laying, there will be empty parts inside. This will reduce the overall compressive strength of the MMP pipes underground and cause deformation during long-term use. Utility Model Content
[0004] The purpose of this utility model is to provide a wear-resistant and pressure-resistant plastic pipe to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A wear-resistant and pressure-resistant plastic pipe includes an MMP pipe and multiple protective units equidistantly installed on the MMP pipe. Each protective unit includes an upper connecting seat, a lower connecting seat, and two threaded rods. Both the upper and lower connecting seats have arc-shaped grooves that abut against the surface of the MMP pipe. The central axes of the upper and lower connecting seats coincide with the central axis of the end face of the MMP pipe. The two threaded rods are vertically fixed to the lower connecting seat, and the upper connecting seat is vertically slidably connected between the two threaded rods.
[0007] Preferably, each threaded rod has two vertically slidingly connected limiting blocks, one side of each limiting block abutting the surface of the MMP tube, and the other side of each limiting block abutting the upper connecting seat and the lower connecting seat, respectively.
[0008] Preferably, both the upper connecting seat and the lower connecting seat are provided with a first inclined surface, and both limiting blocks are provided with a second inclined surface, the second inclined surface abutting against the first inclined surface.
[0009] Preferably, a side baffle is fixedly connected between the two limiting blocks of two adjacent protective units, and one side of the side baffle is set as an arc surface, which abuts against the surface of the MMP tube.
[0010] Preferably, the top of the threaded rod is threadedly connected to an end cap, and a gasket is fitted on the threaded rod, with the gasket located between the end cap and the upper connecting seat.
[0011] Preferably, the bottom surface of the lower connecting seat is set as a plane.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention incorporates an upper and lower connector on the MMP pipe. When transporting the MMP pipe by truck, the lower connector contacts the truck bed, providing wear-resistant protection for the MMP pipe. When the MMP pipe is buried underground, four limiting blocks support the sides of the MMP pipe, working in conjunction with the upper and lower connectors to increase the overall deformation resistance and thus provide pressure resistance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution:
[0021] A wear-resistant and pressure-resistant plastic pipe includes an MMP pipe 1 and multiple protective units equidistantly installed on the MMP pipe 1. Each protective unit includes an upper connecting seat 2, a lower connecting seat 3, and two threaded rods 4. Both the upper connecting seat 2 and the lower connecting seat 3 have arc-shaped grooves 5, which abut against the surface of the MMP pipe 1. The central axes of the upper connecting seat 2 and the lower connecting seat 3 coincide with the central axis of the end face of the MMP pipe 1. The two threaded rods 4 are vertically fixed to the lower connecting seat 3. The upper connecting seat 2 is vertically slidably connected between the two threaded rods 4. The bottom surface of the lower connecting seat 3 is set as a plane.
[0022] Please see Figure 1 In this embodiment, the MMP pipe 1 is protected by installing the upper connecting seat 2 and the lower connecting seat 3 on the MMP pipe 1. The upper connecting seat 2 and the lower connecting seat 3 act directly on the MMP pipe 1. Multiple upper connecting seats 2 can be used to directly place the MMP pipe 1 in the truck bed. Even if there is friction between the upper connecting seat 2 and the truck bed, it will not damage the surface of the MMP pipe 1. Since the bottom surface of the lower connecting seat 3 is flat, there is no need to use additional clamps to fix the MMP pipe 1 in the truck bed. Multiple MMP pipes 1 can be stacked with the upper connecting seat 2. However, when stacking, attention should be paid to the position of the threaded rod 4 to prevent damage to the threaded rod 4.
[0023] Each threaded rod 4 has two vertically slidingly connected limit blocks 6. One side of each limit block 6 abuts against the surface of the MMP tube 1, and the other side of each limit block abuts against the upper connecting seat 2 and the lower connecting seat 3, respectively.
[0024] Please see Figure 1 and Figure 2 When MMP pipe 1 is used and buried underground, it will be subjected to pressure from the soil. At this time, the soil will squeeze MMP pipe 1 above the upper connecting seat 2. When MMP pipe 1 is subjected to pressure, both sides will deform outward. However, since the limiting block 6 can support from the side of MMP pipe 1, it can prevent the sides of MMP pipe 1 from deforming, thereby increasing the overall compressive strength.
[0025] Both the upper connecting seat 2 and the lower connecting seat 3 are provided with a first inclined surface 7, and both limiting blocks 6 are provided with a second inclined surface 8, with the second inclined surface 8 abutting against the first inclined surface 7.
[0026] Please see Figure 2 Through the contact of the first inclined surface 7 and the second inclined surface 8, the two limiting blocks 6 can abut against the upper connecting seat 2 and the lower connecting seat 3 respectively, thereby increasing the stability of the entire protective unit.
[0027] A side baffle 9 is fixedly connected between the two limiting blocks 6 of two adjacent protective units. One side of the side baffle 9 is set as an arc surface 10, which abuts against the surface of the MMP tube 1.
[0028] Please see Figure 3 The side baffle 9 connects two adjacent horizontal limiting blocks 6, thus providing axial support for the MMP tube 1. In actual use, the length of the side baffle 9 needs to be cut according to the actual length of the MMP tube 1. The connection between the side baffle 9 and the limiting block 6 can be adhesive or bolted to ensure the stability between the side baffle 9 and the limiting block 6. The arc surface 10 is designed to make the side baffle 9 fit better on the MMP tube 1. The specifications of the side baffle 9 need to be changed according to the actual size of the MMP tube 1 so that the center of the arc surface 10 falls on the axis of the MMP tube 1.
[0029] The top of the threaded rod 4 is threadedly connected to an end cap 11, and a gasket 12 is fitted on the threaded rod 4. The gasket 12 is located between the end cap 11 and the upper connecting seat 2.
[0030] The end cap 11 seals one end of the threaded rod 4 to prevent the upper connecting seat 2 from falling off the threaded rod 4. The threaded rod 4 enables a tight connection between the upper connecting seat 2, the lower connecting seat 3, and the two limiting blocks 6. At the same time, the gasket 12 increases the friction between the end cap 11 and the upper connecting seat 2 to prevent the end cap 11 from falling off. In this embodiment, the gasket 12 is made of rubber.
[0031] Because the MMP pipe 1 is equipped with an upper connecting seat 2 and a lower connecting seat 3, the lower connecting seat 3 can contact the truck bed when the MMP pipe 1 is transported by truck, thereby providing wear-resistant protection for the MMP pipe 1. When the MMP pipe 1 is buried underground, the four limiting blocks 6 can support the sides of the MMP pipe 1, and together with the upper connecting seat 2 and the lower connecting seat 3, increase the overall deformation resistance and thus play a role in resisting pressure.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
