Description

Technical Field

[0001] This utility model relates to the field of cable protection pipes, specifically a CPVC power cable protection pipe. Background Technology

[0002] CPVC power conduits are commonly used as cable protection conduits. Cable protection conduits are metal protective pipes with a certain mechanical strength, laid on the outer surface of cables to prevent damage. A search reveals a CPVC power cable protection conduit disclosed in application number CN202223210838.2, which describes a conduit comprising a fixed disc, a first protective pipe fixedly connected to the fixed disc, a sliding plate slidably connected to the surface of a second protective pipe, two through rods fixedly mounted on the surface of the sliding plate, limit holes formed on the outer wall surface of each of the two through rods, two through holes formed on the surface of the fixed disc, and sliding rods fixedly mounted on the annular outer wall surface at both ends of the fixed disc. Slide plates are slidably connected to the surfaces of the two sliding rods, and the surfaces of the slide plates are fixedly mounted... A limit rod is installed, and a limit plate is fixedly installed on the surface of the sliding rod away from the fixed plate. A spring is fixedly installed between the limit plate and the sliding plate. This solves the problem that the existing protective pipes do not have good sturdiness during assembly, which leads to loosening at the connection when the protective pipe with cable is buried underground due to insufficient sturdiness, thus affecting the protective effect of the protective pipe. However, the above description still has the following defects in actual use: the connection of the power cable protective pipe cannot be adjusted at the bend during connection, which restricts its use and affects the overall use. At the same time, it cannot spatially isolate the internal cables to avoid affecting the structure and causing entanglement. Therefore, it is necessary to design a more practical CPVC power cable protective pipe. Utility Model Content

[0009] As a preferred embodiment of this utility model: the inner wall of the flexible bend is provided with a plurality of sliding grooves, and the inner walls of the plurality of sliding grooves are slidably engaged with the side of the elastic isolation frame.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1 - Figure 5 A CPVC power cable protection pipe includes two connected protective pipes 1. Each of the two protective pipes 1 has a first mounting ring 11 at one of its opposite ends. The opposite sides of the two first mounting rings 11 are connected to a bending assembly 2 by a limiting member 12.

The inner wall of the elastic connecting tube 21 is interlocked with the surface of the protective layer 13.

[0029] In practical use: Move the two sets of snap-fit ​​rods 124 along the inner walls of the two sets of mounting sleeves 123 until the two sets of snap-fit ​​rods 124 engage with the inner walls of the two sets of snap-fit ​​holes 122 on the surface of the two second mounting rings 121. Insert the two sets of limiting pins 126 into the two sets of corresponding positioning holes 125 and limiting holes 127 to complete the limiting between the two sets of snap-fit ​​rods 124, mounting sleeves 123 and second mounting rings 121. When not bending, ensure the straightness of the connection between the two protective tubes 1. Conversely, disassemble the limiting component 12 structure and bend the elastic connecting tube 21. The elastic bending strips 22 on the inner walls of several strip grooves 25 bend accordingly and limit the bent elastic connecting tube 21 according to their characteristics. At the same time, several bending pleated sleeves 24 extend and fold according to the bending angle, further providing auxiliary limiting for the bending of the elastic connecting tube 21 and improving the adjustability of the CVPC power cable protection tube connection.

[0030] Please see Figure 5 Isolation component 3 includes a flexible bend 31 installed on the inner wall of the protective layer 13. An elastic isolation frame 32 is fitted into the inner wall of the flexible bend 31. An installation strip 33 is provided at the corner of the inner wall of the elastic isolation frame 32. An arc groove 34 is opened at the corner of several installation strips 33. The inner wall of several arc grooves 34 is fitted with several cables.

[0031] In practical use: the sides of the elastic isolation frame 32 are engaged with several grooves 35 on the inner wall of the flexible bend 31, and the two are combined and fixed. Several mounting strips 33 at the corners of the inner wall of the elastic isolation frame 32, together with several arc grooves 34, are inserted and engaged with the surfaces of several cables. The elastic compression characteristics of the mounting strips 33 are used to elastically limit the cables, thereby preventing the cables from getting tangled inside the CPVC power cable protection pipe.

[0032] Please see Figure 2 The limiting component 12 includes two second mounting rings 121. Each of the two second mounting rings 121 has two sets of snap-fit ​​holes 122 on its opposite side. The inner walls of the two sets of snap-fit ​​holes 122 are engaged with snap-fit ​​rods 124 that are inserted at both ends of the two sets of mounting sleeves 123. Each of the two sets of mounting sleeves 123 has two positioning holes 125 on its surface at both ends. The inner walls of the two sets of positioning holes 125 can be engaged with the limiting holes 127 on the opposite end surface of the two sets of snap-fit ​​rods 124 by limiting pins 126.

[0033] In practical use: move the two sets of snap-fit ​​rods 124 on the inner walls of the two sets of mounting sleeves 123 until the two sets of snap-fit ​​rods 124 engage with the inner walls of the two sets of snap-fit ​​holes 122 on the surface of the two second mounting rings 121, and insert the two sets of limiting pins 126 into the two sets of corresponding positioning holes 125 and limiting holes 127 to complete the limiting between the two sets of snap-fit ​​rods 124, mounting sleeves 123 and second mounting rings 121, ensuring the straightness of the connection between the two protective tubes 1 when not bending.

[0034] Please see Figure 4 The surface of the elastic connecting tube 21 is provided with several strip-shaped slots 25, and the inner walls of the several strip-shaped slots 25 are connected to several elastic bending strips 22 by an adhesive layer.

[0035] In practical use: several elastic bending strips 22 are engaged with the inner walls of several strip-shaped slots 25, thereby installing and fixing them to the elastic connecting pipe 21.

[0036] Please see Figure 5 The inner wall of the flexible bend 31 is provided with several grooves 35, and the inner wall of the several grooves 35 slides and engages with the side of the elastic isolation frame 32.

[0037] In practical use: the side of the elastic isolation frame 32 is engaged with the inner wall of several sliding grooves 35, thereby fixing it to the inner wall of the flexible bend 31. The flexible bend 31 provides an auxiliary function when the bending structure is bent, thereby preventing the overall structure from breaking due to stress.

[0038] Please see Figure 3 The protective layer 13 consists of a plastic layer 131, a base layer 132, a reinforcing layer 133, and an explosion-proof layer 134 from the inside out. The base layer 132 is made of CPVC material.

[0039] In practical use: the plastic layer 131, base layer 132, reinforcing layer 133 and explosion-proof layer 134 in the protective layer 13 help to increase the strength, insulation and explosion-proof properties of the protective tube.

[0040] Please see Figure 2 The surface of the first mounting ring 11 has a plurality of mounting holes 14, and the inner walls of the plurality of mounting holes 14 are threadedly connected to the plurality of slots 128 on the surface of the second mounting ring 121 by mounting bolts 15.

[0041] In practical use: Insert several mounting bolts 15 into several mounting holes 14 and slots 128 to install and fix the two first mounting rings 11 and the second mounting ring 121, thereby completing the installation and fixing of the two protective tubes 1 and the curved structure.

[0042] Please see Figure 1 The surface of the protective tube 1 is provided with an anti-wear coating, and both the anti-wear coating and the protective tube 1 are made of PVC material.

[0043] In practical use: the protective tube 1 made of PVC material, combined with the anti-wear coating on the surface, can improve the wear resistance of the protective tube.

[0044] In use, the two sets of locking rods 124 are moved along the inner walls of the two sets of mounting sleeves 123 until the two sets of locking rods 124 engage with the inner walls of the two sets of locking holes 122 on the surface of the two second mounting rings 121. The two sets of limiting pins 126 are then inserted into the two sets of corresponding positioning holes 125 and limiting holes 127, thus completing the limiting of the two sets of locking rods 124, mounting sleeves 123, and second mounting rings 121. This ensures the straightness of the connection between the two protective tubes 1 when not bent. Conversely, the limiting component 12 structure is disassembled, and the elastic connecting tube 21 is bent. The elastic bending strips 22 on the inner walls of the several strip-shaped locking grooves 25 bend accordingly, and their elasticity is adjusted according to their characteristics after bending. The connecting tube 21 is limited, and several curved pleated sleeves 24 extend and fold according to the bending angle, further providing auxiliary limit for the bending of the elastic connecting tube 21, improving the adjustability of the CVPC power cable protection pipe connection; the side of the elastic isolation frame 32 is engaged with several sliding grooves 35 on the inner wall of the flexible bend 31, and the two are combined and fixed. Several mounting strips 33 at the corner of the inner wall of the elastic isolation frame 32, together with several arc grooves 34, are inserted and engaged with the surface of several cables. The elastic compression characteristics of several mounting strips 33 elastically limit several cables, preventing the cables from tangling inside the CPVC power cable protection pipe.
