Description
Technical Field
[0001] This utility model relates to the field of CPVC cable conduit technology, and specifically discloses a protective tube that facilitates the placement of CPVC cables. Background Technology
[0002] CPVC cable protection pipes use PVC-C resin as the base material. This product features high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, excellent insulation performance, resistance to aging, light weight, and convenient construction. Its performance surpasses traditional asbestos cable conduits and ordinary PVC pipes, making it an ideal replacement for traditional power cable sheathing pipes. It is widely used in urban power grid construction and renovation projects; urban municipal renovation projects; civil aviation airport construction; industrial park and residential community construction; transportation and road / bridge construction; and urban street light cable laying, serving both guiding and protective functions.
[0003] Chinese Patent Publication No. CN214280769U discloses a protective tube for easy placement of CPVC cables, relating to the field of CPVC cable conduit technology. It includes a first tube body and a second tube body disposed inside the first tube body. The second tube body includes a connecting plate and multiple frames disposed outside the connecting plate. Several cable clamps are fixed to the outer side of the frames for clamping the cables. Several positioning grooves are formed on the inner wall of the first tube body, and several positioning plates are fixed to the outer side of the frames. The positioning plates are used to insert into the inner side of the positioning grooves. The second tube body and cable clamps provided by this utility model can fix the cables, and the second tube body with the fixed cables can be smoothly inserted into the first tube body. With the cooperation of the positioning plates and positioning grooves, the insertion operation of the second tube body is simple and quick. In addition, when the positioning plates are inserted into the positioning grooves, the cable clamps will not touch the inner wall of the first tube body, preventing the cable clamps from being squeezed and damaged during insertion.
[0004] With the rapid development of technology, the above-mentioned device has the following shortcomings:
[0005] 1. When using the above device, multiple cables need to be passed through the first conduit. When it is necessary to protect the middle part of the cable, the first conduit needs to be moved from the end of the cable to the middle part of the cable, which makes the above device cumbersome and inconvenient to use during installation.
[0006] 2. When the entire cable needs to be protected, the installers need to repeatedly move multiple first tubes from the end of the cable to the position to be protected, which makes the installation of the above-mentioned device time-consuming and labor-intensive, and seriously increases the workload of the installers. Utility Model Content
[0007] This utility model proposes a protective tube that facilitates the placement of CPVC cables, eliminating the need for cable threading, simplifying installation and use, and eliminating the need for installers to move the outer cylinder, effectively reducing the workload of installers.
[0008] This utility model is implemented as follows: a protective tube for easy placement of CPVC cables includes a protective outer cylinder, the protective outer cylinder includes an upper cover cylinder and a lower cover cylinder, and a locking mechanism is provided between the upper cover cylinder and the lower cover cylinder;
[0009] The protective outer cylinder has a support with a cross-shaped cross section and the same length as the protective outer cylinder inside. The outer wall of the support is fixedly connected to multiple evenly distributed mounting rings, and the outer wall of the mounting rings is fixedly connected to multiple arrayed cable clips.
[0010] As a preferred embodiment of the present invention for a protective tube that facilitates the placement of CPVC cables, the locking mechanism includes a first notch and a second notch respectively provided on the lower end of the outer wall of the upper cover cylinder and the upper end of the inner wall of the lower cover cylinder and matching each other. Limiting strips are fixedly connected to the side walls opposite to the two first notches, and limiting grooves that match the two limiting strips are provided on the side walls opposite to the two second notches.
[0011] As a preferred embodiment of the present invention for facilitating the placement of CPVC cables, the outer wall of the bracket is fixedly connected with multiple sets of support rods that are staggered with multiple mounting rings. Each set of support rods is arranged in an array, and the end of each set of support rods is in close contact with the inner wall of the protective outer cylinder.
[0012] As a preferred embodiment of the present invention for facilitating the placement of CPVC cables, both the upper and lower cover tubes have cavities inside, and multiple evenly distributed reinforcing rods are fixedly connected inside the cavities.
[0013] As a preferred embodiment of the present invention for a protective tube that facilitates the placement of CPVC cables, the locking mechanism further includes two bolts that are threaded through and connected to both sides of the outer wall of the lower cover cylinder and distributed front to back. Two threaded grooves are provided on the opposite side walls of the two limiting strips. One end of each of the bolts extends into the interior of the multiple threaded grooves and is threadedly connected to them.
[0014] As a preferred embodiment of this utility model for facilitating the placement of CPVC cables, the cable clip is made of silicone.
[0015] As a preferred embodiment of this utility model for facilitating the placement of CPVC cables, the plurality of reinforcing rods are distributed in a triangular structure.
[0016] The beneficial effects of this utility model are:
[0017] Multiple CPVC cables are sequentially inserted into multiple cable clips to secure them. The upper cover is then placed over the support, and the lower cover is moved to the lower end of the upper cover, aligning the two limiting strips with the two limiting grooves. The lower cover is then pushed to move the two limiting strips into the two limiting grooves until it aligns with both ends of the upper cover. Finally, the upper and lower covers are secured using multiple bolts and threaded grooves. This eliminates the need for cable threading, making the installation and use of the CPVC cable protection pipe simple and convenient.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0025] Please see Figure 1-4 A protective tube for easy placement of CPVC cables includes a protective outer tube 1, the protective outer tube 1 includes an upper cover tube 2 and a lower cover tube 3, and a locking mechanism is provided between the upper cover tube 2 and the lower cover tube 3.
[0026] The outer protective cylinder 1 has a support 4 with a cross-shaped cross section and the same length as the outer protective cylinder 1. The outer wall of the support 4 is fixedly connected with multiple evenly distributed mounting rings 5. The outer wall of the mounting rings 5 is fixedly connected with multiple arrayed cable clips 6.
[0027] In this embodiment: When in use, the upper cover cylinder 2 and the lower cover cylinder 3 are disassembled, and the bracket 4 is taken out separately. Then the bracket 4 is moved to the position where multiple CPVC cables need to be protected, and the bracket 4 is placed between multiple CPVC cables. Then the multiple CPVC cables are sequentially inserted into multiple cable clips 6, and the multiple CPVC cables are fixed by multiple cable clips 6.
[0028] After fixing, place the upper cover 2 on top of the bracket 4, aligning both ends of the upper cover 2 with the two ends of the bracket 4. Then, move the lower cover 3 to the lower end of the upper cover 2, aligning the two limiting strips 9 with the two limiting grooves 10. Push the lower cover 3 to move it, allowing the two limiting strips 9 to enter the two limiting grooves 10 until the lower cover 3 is aligned with both ends of the upper cover 2. Then, fix the upper cover 2 and lower cover 3 by the mutual cooperation of multiple bolts 14 and multiple threaded grooves 15. At this time, multiple sets of support rods 11 and the inner of the protective outer cylinder 1 are connected. The wall abutment provides support for the outer protective cylinder 1, ensuring that the center of the outer protective cylinder 1 and the mounting ring 5 are on the same straight line. Since the end of each set of support rods 11 is tightly abutted against the inner wall of the outer protective cylinder 1, the outer protective cylinder 1 can be limited through the mutual cooperation between the outer protective cylinder 1 and multiple sets of support rods 11, preventing the outer protective cylinder 1 from sliding arbitrarily and misaligning with the bracket 4. This eliminates the need to thread the cable through the bracket, making the installation and use of the CPVC cable protective tube simple and convenient, and eliminating the need for installers to move the outer protective cylinder 1, effectively reducing the workload of installers.
[0029] As a technical optimization of this utility model, the locking mechanism includes a first notch 7 and a second notch 8 that are respectively opened at the lower end of the outer wall of the upper cover cylinder 2 and the upper end of the inner wall of the lower cover cylinder 3 and match each other. The side walls of the two first notches 7 opposite to each other are fixedly connected with limit strips 9, and the side walls of the two second notches 8 opposite to each other are provided with limit grooves 10 that match the two limit strips 9 respectively.
[0030] In this embodiment: the two limiting strips 9 and the two limiting grooves 10 facilitate the vertical positioning and fixing between the upper cover cylinder 2 and the lower cover cylinder 3. By opening two first notches 7 and two second notches 8, the inner and outer walls of the outer protective cylinder 1 can be made smooth.
[0031] As a technical optimization of this utility model, the outer wall of the bracket 4 is fixedly connected with multiple sets of support rods 11 that are staggered with multiple mounting rings 5. Each set of support rods 11 is arranged in an array, and the end of each set of support rods 11 is in close contact with the inner wall of the protective outer cylinder 1.
[0032] In this embodiment, multiple sets of support rods 11 can support the protective outer cylinder 1, so that the center of the protective outer cylinder 1 and the mounting ring 5 are on the same straight line, preventing the protective outer cylinder 1 from shaking randomly. At the same time, since the end of each set of support rods 11 is in close contact with the inner wall of the protective outer cylinder 1, the protective outer cylinder 1 can be limited by the cooperation between the protective outer cylinder 1 and the multiple sets of support rods 11, preventing the protective outer cylinder 1 from sliding randomly and misaligning with the bracket 4.
[0033] As a technical optimization of this utility model, both the upper cover cylinder 2 and the lower cover cylinder 3 have cavities 12 inside, and multiple evenly distributed reinforcing rods 13 are fixedly connected inside the cavities 12.
[0034] In this embodiment: the cavity 12 can reduce the weight of the upper cover cylinder 2 and the lower cover cylinder 3, and the multiple reinforcing rods 13 can strengthen the structural strength of the upper cover cylinder 2 and the lower cover cylinder 3.
[0035] As a technical optimization of this utility model, the locking mechanism also includes two bolts 14 that are threaded through and connected to both sides of the outer wall of the lower cover cylinder 3 and distributed front and back. Two threaded grooves 15 distributed front and back are opened on the opposite side walls of the two limiting strips 9. One end of the multiple bolts 14 extends into the interior of the multiple threaded grooves 15 and is threadedly connected to them.
[0036] In this embodiment, the horizontal orientation of the upper cover cylinder 2 and the lower cover cylinder 3 can be fixed by the mutual cooperation between multiple bolts 14 and multiple threaded grooves 15.
[0037] As a technical optimization of this utility model, the cable clip 6 is made of silicone.
[0038] In this embodiment, the cable clip 6 is made of silicone, which allows the cable clip 6 to deform while clamping and fixing the CPVC cable.
[0039] As a technical optimization of this utility model, the multiple reinforcing rods 13 are distributed in a triangular structure.
[0040] In this embodiment, the multiple reinforcing rods 13 are distributed in a triangular structure, which can further increase the reinforcing effect of the multiple reinforcing rods 13 on the upper cover cylinder 2 and the lower cover cylinder 3 structure.
[0041] The working principle and usage process of this utility model are as follows: When in use, the upper cover cylinder 2 and the lower cover cylinder 3 are disassembled, and the bracket 4 is taken out separately. Then, the bracket 4 is moved to the position where multiple CPVC cables need to be protected, and the bracket 4 is placed between multiple CPVC cables. Then, multiple CPVC cables are inserted into multiple cable clips 6 in sequence, and multiple CPVC cables are fixed by multiple cable clips 6.
[0042] After fixing is completed, the upper cover tube 2 is placed on top of the bracket 4, and the two ends of the upper cover tube 2 are aligned with the two ends of the bracket 4. Then, the lower cover tube 3 is moved to the lower end of the upper cover tube 2, and the two limiting strips 9 are aligned with the two limiting grooves 10 respectively. Then, the lower cover tube 3 is pushed to move, so that the two limiting strips 9 enter the two limiting grooves 10 respectively, until the lower cover tube 3 moves to be aligned with the two ends of the upper cover tube 2. Then, the upper cover tube 2 and the lower cover tube 3 are fixed by the mutual cooperation between the multiple bolts 14 and the multiple threaded grooves 15.
