Description

Technical Field

[0001] This application relates to the field of PVC corrugated pipe technology, and in particular to a pressure-resistant and corrosion-resistant PVC corrugated pipe for the protection of communication cables. Background Technology

[0002] Currently, PVC corrugated pipes have become a key material for protecting communication cables due to their excellent compressive strength and corrosion resistance. Their unique corrugated structure design can withstand external mechanical pressure and adapt to the corrosion protection requirements of complex environments, providing a reliable guarantee for the safe operation and long-term stability of communication cables.

[0003] However, existing pressure-resistant and corrosion-resistant PVC corrugated pipes for communication cable protection have the following drawbacks: for example, some PVC corrugated pipes use a heat fusion connection method, which requires the use of professional heat fusion equipment, places high demands on the technical skills of construction personnel, and the heat fusion process requires a certain heating and cooling time, making the operation cumbersome and seriously affecting construction efficiency. Utility Model Content

[0004] The purpose of this application is to make the disassembly and assembly of the first corrugated pipe and the second corrugated pipe quicker and more time-saving.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a pressure-resistant and corrosion-resistant PVC corrugated pipe for communication cable protection, comprising a first corrugated pipe, an installation block fixedly connected to the outer surface of the right end of the first corrugated pipe, a turbine ring rotatably installed inside the installation block, four inclined grooves being formed on the side wall of the turbine ring, a moving rod being provided inside the inclined groove, a connecting block being fixedly connected to the side wall of the moving rod, a locking block being fixedly connected to the side of the connecting block away from the moving rod, a second corrugated pipe being provided on the right side of the first corrugated pipe, a fixing ring being fixedly connected to the outer surface of the left end of the second corrugated pipe, four locking grooves being formed on the outer surface of the fixing ring, a locking block being located inside the locking groove, a worm gear being rotatably installed inside the installation block, the worm gear meshing with the turbine ring, and a torsion block being fixedly connected to the side wall of the worm gear.

[0006] As a preferred embodiment, the first bellows has a first rotating groove inside, and the worm gear is located inside the first rotating groove.

[0007] As another preferred embodiment, the mounting block has a second rotating groove inside, and the turbine ring is located inside the second rotating groove.

[0008] Further preferably, the inner wall of the second rotating groove is provided with a second moving groove, and the number of the second moving groove is four, with the connecting block located inside the second moving groove.

[0009] As a preferred embodiment, the inner wall of the second movable groove is provided with a first movable groove, and the locking block is located inside the first movable groove.

[0010] As another preferred embodiment, the inner surfaces of both the first and second corrugated pipes are provided with guide grooves, and the number of guide grooves is three. The inner surfaces of both the first and second corrugated pipes are fixedly connected with anti-corrosion coatings.

[0011] In a further preferred embodiment, a limiting groove is formed on the inner surface of the mounting block, and a limiting block is fixedly connected to the outer surface of the fixing ring, with the limiting block located inside the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] Compared with existing technologies, this pressure-resistant and corrosion-resistant PVC corrugated pipe for communication cable protection comprises a first corrugated pipe, a second corrugated pipe, a fixing ring, a mounting block, a slot, a first moving slot, a torsion block, a worm gear, a turbine ring, a moving rod, an inclined slot, a connecting block, and a locking block. When the first and second corrugated pipes need to be connected together, the fixing ring is first placed in a position that fits against the inner surface of the mounting block, so that the slot corresponds to the position of the first moving slot. Twisting the torsion block drives the worm gear to rotate, which in turn drives the turbine ring to rotate. Since the moving rod is located in the inclined slot, it can drive adjacent moving rods to move closer or further apart. When adjacent moving rods move closer together, adjacent... The connecting block and the locking block approach each other, and the locking block enters the locking slot until the worm gear stops rotating. At this point, the first and second corrugated pipes are connected. When it is necessary to separate the first and second corrugated pipes, simply twist the torsion block in the opposite direction. Compared with existing PVC corrugated pipes, the hot-melt connection method requires the use of professional hot-melt equipment, which places higher demands on the technical skills of the construction personnel. In addition, the hot-melt process requires a certain heating and cooling time, making the operation cumbersome and seriously affecting the construction efficiency. The pressure-resistant and corrosion-resistant PVC corrugated pipe for communication cable protection allows for quicker and more time-saving disassembly and assembly between the first and second corrugated pipes.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-7 The communication cable protection PVC corrugated pipe shown includes a first corrugated pipe 1. A mounting block 2 is fixedly connected to the outer surface of the right end of the first corrugated pipe 1. A turbine ring 3 is rotatably mounted inside the mounting block 2. Four inclined grooves 4 are formed on the side wall of the turbine ring 3. A moving rod 5 is installed inside the inclined groove 4. A connecting block 6 is fixedly connected to the side wall of the moving rod 5. A locking block 7 is fixedly connected to the side of the connecting block 6 away from the moving rod 5. A second corrugated pipe 8 is provided on the right side of the first corrugated pipe 1. Both the first corrugated pipe 1 and the second corrugated pipe 8 are PVC corrugated pipes, which have pressure resistance and wear resistance. A fixing ring 9 is fixedly connected to the outer surface of the left end of the second corrugated pipe 8. Four locking grooves 10 are formed on the outer surface of the fixing ring 9. The locking block 7 is located inside the locking groove 10. The mounting block 2 is rotatably mounted inside the mounting block 2. The device is equipped with a worm gear 11, which meshes with the turbine ring 3. When it is necessary to connect the first bellows 1 and the second bellows 8 together, the fixing ring 9 is first placed in a position that fits against the inner surface of the mounting block 2, so that the slot 10 corresponds to the position of the first moving slot 14. Twisting the torsion block 12 drives the worm gear 11 to rotate, which in turn drives the turbine ring 3 to rotate. Since the moving rod 5 is located in the inclined slot 4, it can drive the adjacent moving rod 5 to move closer or further away from each other. When the adjacent moving rod 5 moves closer to each other, the adjacent connecting block 6 and the locking block 7 move closer to each other, and the locking block 7 enters the slot 10 until the worm gear 11 can no longer rotate and stops rotating. At this time, the first bellows 1 and the second bellows 8 are connected. When it is necessary to separate the first bellows 1 and the second bellows 8, it is only necessary to twist the torsion block 12 in the opposite direction. The torsion block 12 is fixedly connected to the side wall of the worm gear 11.

[0027] The first bellows 1 has a first rotating groove 13 inside, and the worm gear 11 is located inside the first rotating groove 13. The first rotating groove 13 can provide the space required for the worm gear 11 to rotate. The mounting block 2 has a second rotating groove 16 inside, and the turbine ring 3 is located inside the second rotating groove 16. The second rotating groove 16 can provide the space required for the turbine ring 3 to rotate. The inner wall of the second rotating groove 16 has a second moving groove 15. There are four second moving grooves 15. The connecting block 6 is located inside the second moving groove 15. The second moving groove 15 can restrict the movement of the connecting block 6 and prevent the connecting block 6 from rotating when it moves. The inner wall of the second moving groove 15 has a first moving groove 14. The locking block 7 is located inside the first moving groove 14. The first moving groove 14 can restrict the movement of the locking block 7.

[0028] The inner surfaces of the first corrugated pipe 1 and the second corrugated pipe 8 are each provided with a guide groove 17, and there are three guide grooves 17. The inner surfaces of the first corrugated pipe 1 and the second corrugated pipe 8 are fixedly connected with an anti-corrosion coating 18. The guide grooves 17 can guide the water that seeps into the pipes due to the humid environment and discharge it along the guide grooves 17. A water pipe can be connected to the outside of a section of the corrugated pipe to discharge the water in the guide grooves 17. The anti-corrosion coating 18 is made of polytetrafluoroethylene, which has good corrosion resistance. The inner surface of the mounting block 2 is provided with a limiting groove 19, and the outer surface of the fixing ring 9 is fixedly connected with a limiting block 20. The limiting block 20 is located inside the limiting groove 19. The limiting block 20 and the limiting groove 19 can facilitate the docking of the first corrugated pipe 1 and the second corrugated pipe 8 during installation.

[0029] Working principle: When it is necessary to connect the first bellows 1 and the second bellows 8 together, first place the fixing ring 9 in a position that fits against the inner surface of the mounting block 2, so that the slot 10 corresponds to the position of the first moving slot 14. Twist the torsion block 12 to drive the worm gear 11 to rotate, which in turn drives the turbine ring 3 to rotate. Since the moving rod 5 is located in the inclined slot 4, it can drive the adjacent moving rod 5 to move closer or further away from each other. When the adjacent moving rod 5 moves closer to each other, the adjacent connecting block 6 and the locking block 7 move closer to each other, and the locking block 7 enters the slot 10 until the worm gear 11 can no longer rotate and stops rotating. At this time, the first bellows 1 and the second bellows 8 are connected. When it is necessary to separate the first bellows 1 and the second bellows 8, simply twist the torsion block 12 in the opposite direction.
