Description

Technical Field

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

[0002] Cable protection pipes are metal protective pipes 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 steel wire ropes. This protects cables, switches, circuit boards, and even the entire device from being burned out. They also provide some isolation against magnetic field interference from power lines.

[0003] In existing technologies, after the protective pipe is laid, both ends of the pipe should be sealed to prevent foreign objects from entering and affecting the cable laying. The existing sealing is mostly set by threads or snap-fit, which only serves to seal the cable protective pipe. Since multiple sets of cables will accumulate together and generate a lot of heat during the operation of the internal cable, the heat dissipation of the cable protective pipe is poor, which can easily lead to failure during the overall operation of the cable, thereby reducing the overall service life of the cable protective pipe.

[0004] In summary, the above structure will cause multiple cables to accumulate together in the cable protection pipe during actual use, generating a large amount of heat. The cable protection pipe has poor heat dissipation, which can easily lead to failures during the overall operation of the cables, thereby reducing the overall service life of the cable protection pipe. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a cable protection pipe with a plug structure to solve the technical problem that multiple cables will accumulate together in the cable protection pipe, generating a large amount of heat, which can easily lead to failures during the overall operation of the cables, thereby reducing the overall service life of the cable protection pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable protection pipe with a plug structure, comprising a pipe body and a plug body, wherein the plug body is located at both ends of the pipe body, and a guide post is provided at the center of the inner wall of the plug body; a sleeve core is provided inside the pipe body, and an array of cable cavities is formed between the outer wall of the sleeve core and the inner wall of the pipe body; a guide post hole cooperating with the guide post is also provided at the center of the sleeve core; and a clamping mechanism cooperating with the guide post is provided at both ends of the pipe body inside the cable cavity.

[0007] By adopting the above technical solution, multiple cable cavities are formed between the sleeve core and the tube body, ensuring that the cables are installed separately when they are inside the tube body. This prevents the heat from being transferred between the cables during operation. Furthermore, a guide post hole is provided in the middle of the sleeve core for the insertion of guide posts. When the plug body is installed, the guide post is inserted into the guide post hole, and in cooperation with the insertion rod, it drives the sliding clamp to move, thereby completing the limiting and fixing work of both ends of the cable. During this process, part of the cable is suspended in the air, which effectively improves the heat dissipation effect inside the tube body.

[0008] The present invention is further configured such that the clamping mechanism includes a sliding clamping sleeve and a fixed clamping sleeve, wherein the sliding clamping sleeve is located near the guide post hole and the fixed clamping sleeve is located on the inner wall of the tube body.

[0009] Preferably, during the insertion of the guide post, the sliding clamp will slide outward together, and in this process, it will work with the fixing clamp on the inner wall of the tube to limit and support both ends of the cable.

[0010] The present invention is further configured such that an array of insert rods cooperating with the guide post are slidably disposed in the guide post hole, wherein the other end of the insert rod passes through the cable cavity and is connected to a sliding clamping sleeve.

[0011] Preferably, when the guide post is inserted into the guide post hole through the plug body, the guide post will squeeze the insert rod in the guide post hole. During this process, the insert rod will drive the sliding clamping sleeve to slide outward, thereby achieving the clamping work with the fixed clamping sleeve.

[0012] The present invention is further configured such that one end of the insertion rod has an arc-shaped end face on the contact surface with the guide post, and the arc-shaped end face is smooth.

[0013] Preferably, the arc-shaped end face of the guide post will squeeze one end of the insertion rod during the sliding process. The cooperation between the two can prevent the guide post from getting stuck during the sliding process, further improving the overall sliding stability. In addition, the smooth shape reduces the friction between the guide post and the insertion rod, ensuring that the guide post can be stably inserted into the guide post hole to realize the installation of the plug body.

[0014] The present invention is further configured such that an array of heat dissipation fins are provided on the outer wall of the tube.

[0015] Preferably, the heat dissipation fins facilitate the accelerated heat dissipation of the outer wall of the tube, thereby further improving the overall heat dissipation efficiency.

[0016] The present invention is further provided with a sealing protective sleeve on the contact surface between the sleeve core and the tube body, wherein the sleeve core itself is detachable.

[0017] Preferably, the sealed protective sleeve prevents heat from flowing between the cable cavities, and the detachable design facilitates subsequent inspection and maintenance of the internal cables by staff.

[0018] The present invention is further configured such that the pipe body and the plug body are connected by a snap-fit ​​mechanism.

[0019] Preferably, the snap-fit ​​design can speed up the connection between the plug body and both ends of the pipe, reducing the maintenance and disassembly burden on subsequent staff.

[0020] The present invention is further configured such that the outer wall of the guide post and the inner wall of the guide post hole are roughened.

[0021] Preferably, the rough texture improves the stability of the guide post sliding within the sleeve core, preventing the guide post from shifting position due to slight impacts on the outer wall of the tube.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention features a sleeve installed inside the tube, forming multiple cable cavities between the sleeve and the tube. This ensures that the cables are installed separately when inside the tube, preventing heat transfer between them during operation. A guide post hole is provided in the middle of the sleeve for inserting guide posts. When the plug body is installed, the guide post is inserted into the guide post hole, and in conjunction with the insertion rod, it drives the sliding clamp to move, thereby limiting and fixing both ends of the cable. During this process, part of the cable is suspended, effectively improving heat dissipation inside the tube and ensuring the stability of the cable during long-term operation.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] First embodiment:

[0033] Please see Figures 1-4 The cable protection pipe shown includes a pipe body 1, a plug body 2, a sealing mechanism, an installation mechanism, and a heat conduction mechanism. A sleeve core 7 is provided inside the pipe body 1, and an array of cable cavities 8 are formed between the outer wall of the sleeve core 7 and the inner wall of the pipe body 1. The cable cavities 8 ensure that the cables are installed separately when inside the pipe body 1, preventing heat transfer between the cables during operation. The plug body 2 is located at both ends of the pipe body 1, and a guide post 3 is provided at the center of the inner wall of each plug body 2. A guide post hole 9, which mates with the guide post 3, is also provided at the center of the sleeve core 7. An array of guide posts and guide posts are slidably disposed within the guide post hole 9. The insert rod 6 is designed to work with the cable. The other end of the insert rod 6 passes through the cable cavity 8 and is connected to a sliding clamping sleeve 4. The sliding clamping sleeve 4 is located near the guide post hole 9, while the fixed clamping sleeve 5 is located on the inner wall of the tube body 1. When the guide post 3 is inserted into the guide post hole 9 through the plug body 2, the guide post 3 will squeeze the insert rod 6 in the guide post hole 9. During this process, the insert rod 6 will drive the sliding clamping sleeve 4 to slide outward, thereby achieving the clamping work of the fixed clamping sleeve 5, thus completing the limiting and fixing work of both ends of the cable. During this process, part of the cable will be in a suspended state, which effectively improves the heat dissipation effect in the tube body 1 and ensures the stability of the cable during long-term operation.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A sealing protective sleeve is provided at the contact surface between the sleeve core 7 and the tube body 1. The sleeve core 7 itself is detachable. The sealing protective sleeve can prevent heat from flowing through each group of cable cavities, and the detachable design facilitates subsequent inspection and maintenance of the internal cables by the staff.

[0035] Second embodiment:

[0036] Please see Figure 3The cable protection pipe with a plug structure shown is similar in overall structure to that in Embodiment 1. One end of the insertion rod 6 has an arc-shaped end face on the contact surface with the guide post 3. The arc-shaped end face is smooth. During the sliding of the guide post 3, the arc-shaped end face will squeeze one end of the insertion rod 6. The cooperation between the two can prevent the guide post 3 from getting stuck during the sliding process, which further improves the overall sliding stability. In addition, the smooth design reduces the friction between the guide post 3 and the insertion rod 6, ensuring that the guide post 3 can be stably inserted into the guide post hole 9 to realize the installation of the plug body 2.

[0037] In practical operation, this utility model works as follows: When in use, the sleeve core 7 is installed on the inner wall of the tube body 1, forming multiple cable cavities 8 between the sleeve core 7 and the tube body 1. Multiple cable groups are installed together within the tube body 1 through the cable cavities 8, and each group of cables does not come into contact with each other, improving the overall stability of the cable operation. Furthermore, a guide post hole 9 is provided at the center of the sleeve core 7. When the operator installs the plug body 2, the guide post 3 on the inner wall is inserted into the guide post hole 9, thereby compressing the insertion rod 6. During this process, the sliding clamping sleeve 4 moves and, in conjunction with the fixed clamping sleeve 5, supports the cable at the plug body 2, causing some cables to be suspended, effectively improving the heat dissipation effect within the tube and ensuring the stability of the cable during long-term operation.

[0038] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
