Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically to a cable protection pipe that facilitates wire lead-in. Background Technology

[0002] Cable protection pipes are tubular products with a certain mechanical strength that are laid on the outer layer of cables to prevent damage. They are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and wire ropes, thereby protecting cables, switches, circuit boards, and even the entire device from being burned out.

[0003] Utility model patent CN212183037U discloses a cable protection pipe, which includes a main structure comprising an inner protective pipe, an outer protective pipe, and a buffer layer disposed between the inner and outer protective pipes. The inner and outer protective pipes provide dual protection for the cable, enhancing its protective strength. When subjected to a gravitational impact, the outer protective pipe provides rigid protection while simultaneously transferring the impact force to a flexible buffer. The flexible buffer, being a flexible structure, acts as a buffer, preventing the outer protective pipe from colliding rigidly with the original impact source and causing damage, thus improving the cable protection pipe's protective strength and service life. The outer protective pipe and the flexible buffer are not fixedly connected; if the outer protective pipe is damaged, only the outer protective pipe needs to be replaced, while the inner protective pipe and flexible buffer can continue to be used, saving on operating costs.

[0004] Although the cable protection pipe saves on usage costs, the device still has the following problems in actual use: when the cable is passed through the pipe, there will be a large friction between the cable and the inner wall of the pipe. When the pipe is long, the resistance when the cable passes through the pipe will increase as the cable travels, which will increase the difficulty of passing the cable through the pipe. In view of this, we propose a cable protection pipe that is easy to lead the cable. Utility Model Content

[0005] The purpose of this invention is to provide a cable protection tube that facilitates cable lead-in, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cable protection tube for easy cable lead-in includes a tube body. Inside the tube body, a connecting seat is located at the center. Two side plates are fixed to the outer wall of the connecting seat on each of the four sides (top, bottom, left, and right). The ends of the side plates are fixedly connected to the inner wall of the tube body. Two fixing seats are fixed between two adjacent side plates. Multiple grooves are opened on the two opposite end faces of the two fixing seats. A roller for guiding the cable is rotatably installed in the groove. The roller protrudes to the outside of the groove. A connecting shaft is coaxially fixed to both ends of the roller. The connecting shaft passes through the inner wall of the groove and is rotatably connected to the groove.

[0008] Multiple anti-crushing components are provided on the outer periphery of the tube. Each anti-crushing component includes a plate. Multiple connecting rods are fixed to the arc-shaped inner wall of the plate. The ends of the connecting rods pass through the tube and into the inner cavity of the tube. Limiting blocks are coaxially connected to the ends of the connecting rods. Springs are sleeved on the outside of the connecting rods. The two ends of the springs abut against the outer walls of the plate and the tube, respectively.

[0009] Preferably, the overall shape of the plate is arc-shaped, and multiple plates are distributed in a ring at equal intervals.

[0010] Preferably, the outer wall of the plate is fixed with a plurality of transversely distributed transverse ribs, and the outer wall of the plate is also fixed with a plurality of longitudinally distributed longitudinal ribs, and the transverse ribs and longitudinal ribs are distributed in a crisscross pattern.

[0011] Preferably, the limiting block is fixedly connected to the end of the connecting rod by bolts, and the diameter of the connecting rod is smaller than the diameter of the limiting block.

[0012] Preferably, the connecting seat is perpendicular to the side plate, and the connecting seat and the side plate are integrally formed.

[0013] Preferably, the tube body is annular in shape and is made of polyvinyl chloride.

[0014] Preferably, the front end face of the connector has a shaped hole that penetrates the connector.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By installing multiple rollers inside the conduit, when the cable passes between two adjacent rollers, the friction between the cable and the conduit is reduced due to the rotation of the rollers, allowing the cable to pass smoothly inside the conduit, improving the convenience of cable installation and reducing the difficulty of passing the cable through the conduit.

[0017] 2. The anti-pinch component is designed so that when an external object squeezes the plate, the plate is subjected to and compresses the spring. The spring then buffers the squeezing force, thereby reducing the squeezing force on the pipe and protecting the pipe and cable. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] This embodiment provides a technical solution:

[0029] Please see Figures 1-5As shown, a cable protection tube for easy cable routing includes a tube body 1. A connecting seat 2 is located at the center of the tube body 1. Two side plates 21 are fixed to the outer wall of the connecting seat 2 on each of its four sides (top, bottom, left, and right). The ends of the side plates 21 are fixedly connected to the inner wall of the tube body 1. Two fixing seats 22 are fixed between adjacent side plates 21. Multiple grooves 220 are formed on the two opposing end faces of each fixing seat 22. Rollers 23 for guiding cables are rotatably installed within the grooves 220. The rollers 23 protrude beyond the grooves 220. Both ends of 3 are coaxially fixed with connecting shafts 230, which pass through the inner wall of groove 220 and are rotatably connected to groove 220; multiple anti-squeezing components 3 are provided on the outer periphery of tube body 1. The anti-squeezing component 3 includes a plate 30, and multiple connecting rods 33 are fixed on the arc-shaped inner wall of the plate 30. The ends of the connecting rods 33 pass through tube body 1 and into the inner cavity of tube body 1. The ends of the connecting rods 33 are coaxially keyed to limit blocks 35. Springs 34 are sleeved on the outside of the connecting rods 33. The two ends of the springs 34 abut against the outer wall of plate body 30 and tube body 1, respectively.

[0030] In this embodiment, the overall shape of the plate 30 is arc-shaped, and multiple plates 30 are distributed in a ring with equal spacing. The arc-shaped plate 30 has better resistance to compression, ensuring the protective effect of the plate 30.

[0031] In this embodiment, the outer wall of the plate 30 is fixed with a plurality of transversely distributed transverse ribs 32, and the outer wall of the plate 30 is also fixed with a plurality of longitudinally distributed longitudinal ribs 31, and the transverse ribs 32 and longitudinal ribs 31 are arranged in a crisscross pattern. The arrangement of the transverse ribs 32 and longitudinal ribs 31 increases the wear resistance of the plate 30 and ensures the service life of the plate 30.

[0032] In this embodiment, the limiting block 35 is fixedly connected to the end of the connecting rod 33 by bolts, and the diameter of the connecting rod 33 is smaller than the diameter of the limiting block 35. The limiting block 35 limits the connecting rod 33, preventing it from detaching from the tube body 1 and ensuring the installation stability of the plate body 30.

[0033] In this embodiment, the connecting seat 2 is perpendicular to the side plate 21, and the connecting seat 2 and the side plate 21 are integrally formed. The integrally formed connecting seat 2 and the side plate 21 have better connection strength, ensuring the connection stability between the connecting seat 2 and the side plate 21.

[0034] In this embodiment, the overall shape of the tube 1 is ring-shaped, and the tube 1 is made of polyvinyl chloride (PVC). The ring-shaped design facilitates the installation of multiple cables and provides convenient cable protection. The PVC tube 1 has good corrosion resistance, wear resistance, and insulation properties, making it suitable for general indoor and outdoor cable protection.

[0035] In this embodiment, a shaped hole 20 is provided on the front end face of the connecting seat 2, and the shaped hole 20 penetrates the connecting seat 2. The shaped hole 20 increases the structural strength of the connecting seat 2 and the support effect on the multiple side plates 21.

[0036] It is understood that in this embodiment, the end of the side plate 21 is fixedly connected to the inner wall of the pipe body 1 by bolts. The bolt fixing method ensures the reliability and stability of the connection between the side plate 21 and the pipe body 1, and ensures the overall structural strength of the pipe body 1.

[0037] In practical use, the user first passes one end of the cable through the space between the two fixed seats 22. The cable then enters the space between the two rollers 23 and rolls between the two rollers 23. As the rollers 23 roll, the cable moves horizontally and passes through the inside of the tube 1. Repeat the above steps to thread multiple cables in sequence.

[0038] When the plate 30 is compressed, the plate 30 moves under the pressure and drives the connecting rod 33 and the limiting block 35 to move. At the same time, the spring 34 is compressed by the plate 30, and the compressive force is buffered by the spring 34. The pressure on the tube 1 is relatively small.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
