Description

Technical Field

[0001] This utility model relates to the field of MPP pipe technology, specifically to a high tensile strength MPP pipe. Background Technology

[0002] MPP pipe, or modified polypropylene pipe, is a new type of plastic pipe made from polypropylene as the base material and after modification. It is widely used in underground pipeline laying in fields such as power, communications, and municipal engineering. It is especially suitable for trenchless engineering and can effectively protect the surface environment and existing facilities.

[0003] In practical use, existing high tensile strength MPP pipes can cause friction between the cable and the outer wall of the pipe opening during the wiring process. This friction can lead to burrs on the outer wall of the pipe opening damaging the cable's outer wall and damaging the cable's protective layer. Furthermore, after the pipe is laid, the wiring can only be done after the concrete has hardened. During this time, dirt and debris may enter the pipe, requiring prior removal before wiring, which is extremely laborious. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a high tensile strength MPP pipe, which has the advantages of preventing damage to the cable from burrs at the pipe end and sealing the pipe, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high tensile strength MPP pipe, comprising an MPP pipe body, the outer wall of the MPP pipe body having a sliding outer sleeve, the outer wall of the sliding outer sleeve being rotatably connected to a threaded sleeve, the outer wall of the sliding outer sleeve having a limit groove, the outer wall of the sliding outer sleeve being slidably connected to an external threaded cylinder, the inner wall of the external threaded cylinder being fixedly installed with a limit block, the inner wall of the sliding outer sleeve being fixedly installed with a sliding inner sleeve, the outer wall of the external threaded cylinder having a beveled groove, the inner wall of the sliding outer sleeve being slidably connected to an extrusion block, the outer wall of the extrusion block being fixedly installed with a limit plate, the inner wall of the sliding outer sleeve being fixedly installed with a limit post, the inner wall of the sliding outer sleeve having a sealing plate, the outer wall of the sealing plate being fixedly installed with a handle, the outer wall of the sealing plate being rotatably connected with a rotary knob, the outer wall of the rotary knob being fixedly installed with a worm gear, the inner wall of the sealing plate being rotatably connected with a worm wheel, the bottom of the worm wheel being fixedly installed with a threaded post, the inner wall of the sealing plate being slidably connected with a lifting plate, the bottom of the lifting plate being fixedly installed with a friction pressure block, and the inner wall of the sealing plate being fixedly installed with a limit rod.

[0006] As a preferred technical solution of this utility model: the worm is located outside the worm wheel, and the worm meshes with the worm wheel.

[0007] As a preferred technical solution of this utility model: the threaded column passes through the lifting plate, and the threaded column and the lifting plate are connected by threads.

[0008] As a preferred technical solution of this utility model: there are two limiting rods, and the two limiting rods are symmetrically arranged on the inner wall of the sealing plate, and the two limiting rods penetrate through the top of both sides of the lifting plate.

[0009] As a preferred technical solution of this utility model: the number of the limiting plate and the limiting post is four, and the four limiting plates and the limiting post are arranged in a matrix array, with the four limiting posts penetrating the four limiting plates.

[0010] As a preferred technical solution of this utility model: the external threaded cylinder is located on the inner wall of the threaded sleeve, and the external threaded cylinder and the threaded sleeve are connected by threads.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This high tensile strength MPP tube, by rotating the threaded sleeve, causes the threaded sleeve to move the external threaded cylinder, which in turn moves the inclined groove towards the extrusion block. As the inclined groove moves to the outside of the extrusion block, the continued movement of the inclined groove presses the extrusion block downwards, causing the bottom of the extrusion block to fit against the outer wall of the sliding sleeve. The continued downward movement of the inclined groove increases the downward force on the extrusion block, thereby increasing the friction between the extrusion block and the MPP tube body, thus fixing the extrusion block and securing the sliding sleeve to the outside of the MPP tube body. The inclined surfaces on both sides of the sliding sleeve protect the wiring, preventing it from being scratched by the MPP tube body.

[0012] 2. This high tensile strength MPP pipe, by rotating the knob, causes the worm gear to rotate, which in turn meshes with the worm wheel, causing the worm wheel to rotate. The worm wheel then rotates the threaded post at the bottom, causing the threaded post to rotate. This threaded post, through its threaded connection with the lifting plate, moves the lifting plate, which in turn moves the friction block at the bottom. This controls the position of the friction block, ensuring that the threaded post fits against the inner wall of the sliding inner sleeve. This increases the friction between the threaded post and the sliding inner sleeve, thus fixing the sealing plate and sealing the sliding inner sleeve. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1 - Figure 5 A high tensile strength MPP pipe includes an MPP pipe body 1, a sliding outer sleeve 2 slidably sleeved on the outer wall of the MPP pipe body 1, a threaded sleeve 3 rotatably connected to the outer wall of the sliding outer sleeve 2, a limit groove 4 formed on the outer wall of the sliding outer sleeve 2, an external threaded cylinder 5 slidably connected to the outer wall of the sliding outer sleeve 2, a limit block 6 fixedly installed on the inner wall of the external threaded cylinder 5, a sliding inner sleeve 7 fixedly installed on the inner wall of the sliding outer sleeve 2, a beveled groove 8 formed on the outer wall of the external threaded cylinder 5, an extrusion block 9 slidably connected to the inner wall of the sliding outer sleeve 2, and a limit plate 1 fixedly installed on the outer wall of the extrusion block 9. 0. A limit post 11 is fixedly installed on the inner wall of the sliding outer sleeve 2. A sealing plate 12 is provided on the inner wall of the sliding outer sleeve 2. A handle 13 is fixedly installed on the outer wall of the sealing plate 12. A rotary knob 14 is rotatably connected to the outer wall of the sealing plate 12. A worm gear 15 is fixedly installed on the outer wall of the rotary knob 14. A worm wheel 16 is rotatably connected to the inner wall of the sealing plate 12. A threaded post 17 is fixedly installed at the bottom of the worm wheel 16. A lifting plate 18 is slidably connected to the inner wall of the sealing plate 12. A friction pressure block 20 is fixedly installed at the bottom of the lifting plate 18. A limit rod 19 is fixedly installed on the inner wall of the sealing plate 12.

[0017] In the above structure, the limiting block 6 is located on the inner wall of the limiting groove 4, so that the limiting block 6 can only slide on the inner wall of the limiting groove 4 when it moves, thereby limiting the limiting block 6 and preventing it from tilting when it moves, thus preventing the external threaded cylinder 5 from rotating when it moves.

[0018] In a preferred embodiment, the worm 15 is located outside the worm wheel 16, and the worm 15 meshes with the worm wheel 16.

[0019] In the above structure, by rotating the knob 14, the knob 14 drives the worm 15 to rotate, and the worm 15 drives the worm wheel 16 to rotate through meshing with the worm wheel 16, which in turn drives the threaded column 17 at the bottom to rotate.

[0020] In a preferred embodiment, the threaded post 17 passes through the lifting plate 18, and the threaded post 17 and the lifting plate 18 are threadedly connected.

[0021] In the above structure, the rotation of the threaded column 17 causes the threaded column 17 to move through the threaded connection with the lifting plate 18, which in turn causes the lifting plate 18 to move the friction block 20 at the bottom, thereby controlling the position of the friction block 20.

[0022] In a preferred embodiment, there are two limiting rods 19, and the two limiting rods 19 are symmetrically arranged on the inner wall of the sealing plate 12, and the two limiting rods 19 penetrate through the top of both sides of the lifting plate 18.

[0023] In the above structure, two limiting rods 19 pass through both sides of the lifting plate 18, so that the lifting plate 18 can only slide on the outer wall of the two limiting rods 19 when it moves, thus preventing the two lifting plates 18 from tilting when they move.

[0024] In a preferred embodiment, there are four limiting plates 10 and four limiting posts 11, and the four limiting plates 10 and four limiting posts 11 are arranged in a matrix array, with the four limiting posts 11 penetrating through the four limiting plates 10.

[0025] In the above structure, the four limiting plates 10 are penetrated by the four limiting posts 11, so that the four limiting plates 10 are limited by the four limiting posts 11 when they move, and thus the four limiting plates 10 cannot detach from the four limiting posts 11 when they move, so that the four limiting plates 10 limit the extrusion block 9, and thus the extrusion block 9 will not tilt.

[0026] In a preferred embodiment: the external threaded cylinder 5 is located on the inner wall of the threaded sleeve 3, and the external threaded cylinder 5 and the threaded sleeve 3 are threadedly connected.

[0027] In the above structure, by rotating the threaded sleeve 3, the threaded sleeve 3 drives the external threaded sleeve 5 to move through the threaded connection with the external threaded sleeve 5. This causes the external threaded sleeve 5 to move the inclined groove 8 toward the extrusion block 9. As the inclined groove 8 moves to the outside of the extrusion block 9, the continued movement of the inclined groove 8 presses the extrusion block 9 downward, causing the bottom of the extrusion block 9 to fit against the outer wall of the sliding sleeve 2. As the inclined groove 8 continues to move downward, the downward force of the extrusion block 9 increases, thereby increasing the friction between the extrusion block 9 and the MPP tube body 1. This fixes the extrusion block 9, thus fixing the sliding sleeve 2 to the outside of the MPP tube body 1.

[0028] Working principle: When using the equipment, if a cable needs to be passed through the MPP pipe body 1, the threaded sleeve 3 is rotated, causing the threaded sleeve 3 to move through the threaded connection with the external threaded cylinder 5. This, in turn, causes the external threaded cylinder 5 to move the inclined groove 8 towards the extrusion block 9. As the inclined groove 8 moves to the outside of the extrusion block 9, the continued movement of the inclined groove 8 presses the extrusion block 9 downwards, causing its bottom to fit against the outer wall of the sliding sleeve 2. The continued downward movement of the inclined groove 8 increases the downward force on the extrusion block 9, increasing the friction between the extrusion block 9 and the MPP pipe body 1, thus fixing the extrusion block 9 and securing the sliding sleeve 2 to the outside of the MPP pipe body 1. The inclined surface protects the wiring from scratches by the MPP tube body 1. When sealing the MPP tube body 1 is required, the rotary knob 14 is rotated, which in turn drives the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 16, which in turn drives the threaded post 17 at the bottom to rotate. The threaded post 17 is connected to the lifting plate 18 by threads, which in turn moves the lifting plate 18. This causes the lifting plate 18 to move the friction block 20 at the bottom, thus controlling the position of the friction block 20. This allows the threaded post 17 to fit against the inner wall of the sliding inner sleeve 7, increasing the friction between the threaded post 17 and the sliding inner sleeve 7. This fixes the sealing plate 12 and seals the sliding inner sleeve 7.

[0029] 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.
