Description

Technical Field

[0001] This invention relates to the field of cable protection pipe technology, specifically an improved cable protection pipe. 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. The protective pipes usually have corresponding standardized specifications and lengths. In actual projects, due to the influence of the length of a single protective pipe and the cable laying distance, there are often situations where it is necessary to extend or connect the protective pipes. In this case, the protective pipes need to be spliced ​​to meet the actual needs of use.

[0003] Currently, protective pipes are typically spliced ​​together individually using appropriate connectors. However, in actual engineering projects, it is often necessary to splice multiple protective pipes in pairs, such as... Figure 1 As shown, multiple protective tubes are divided into two groups, and the protective tubes in the two groups are spliced ​​one-to-one. The existing splicing of protective tubes is not only inefficient, but also has low convenience in the entire splicing process. Especially in installation environments where the sealing of the protective tubes is required, the sealing of the protective tubes after splicing must be ensured during the splicing process, which further increases the requirements for the splicing of protective tubes. Correspondingly, to a certain extent, it will further reduce the efficiency and convenience of splicing, and may even affect the quality of splicing due to the troublesome splicing process, thereby affecting the overall reliability of the protective tubes. Summary of the Invention

[0004] This invention provides an improved cable protection pipe to solve the problems of low efficiency and convenience in the use of cable protection pipes in related technologies.

[0005] This invention provides an improved cable protection pipe, which includes a modular pipe body. The modular pipe body includes a base frame on which several pipe body units are arranged. A docking mechanism for connecting two sets of modular pipe bodies together is provided. The docking mechanism includes a base with several mating interfaces. The modular pipe bodies are located on both sides of the base. The mating interfaces are located between the two pipe body units being docked. Both ports of the mating interfaces are provided with a pressure sealing element and a clamping locking sealing element. A pressure applying element is provided on the base frame. A locking assembly is symmetrically arranged between the base and the base frame. The locking assembly includes a limiting sliding fastening seat and a fastening element corresponding to the fastening seat. The fastening seats are symmetrically arranged on the base. A control element is provided on the base to control the synchronous reverse sliding of the fastening seats. The fastening elements are respectively connected to the corresponding base frames. The fastening elements automatically fasten with the fastening seats as the base frames move towards the base frames. Then, the control element controls the fastening seats to move synchronously relative to each other to further lock and fix the base frames.

[0006] In one possible implementation, the fastener includes a rotating column that is elastically connected to a limiting block. The rotating column is rotatably connected to the base frame. The fastener seat is a sliding seat with a limiting port. The limiting port includes a cylindrical limiting part, a trumpet-shaped guide part, and an unlocking part that passes through the limiting part and the guide part. During the connection process, after the rotating column passes through the guide part and the limiting part in sequence, the limiting block and the unlocking part are misaligned and automatically engaged in the limiting port. During the unlocking process, the rotating column rotates to align the limiting block with the unlocking part so that it can be easily moved out.

[0007] In one possible implementation, the base is elastically limited and slidably provided with an accompanying limiting member. During the process of the control member controlling the buckle seat to move synchronously relative to each other to further lock and fix the base frame, the accompanying limiting member limits the limiting block.

[0008] In one possible implementation, the compression seal includes an annular sealing ring and a compression ring corresponding to the sealing ring, and the clamping and locking seal includes a clamping portion with an arc-shaped sealing end and a control portion slidably connected to the clamping portion. The clamping portions are symmetrically arranged and slidably connected to the compression ring, and the control portion is slidably connected to the base.

[0009] In one possible implementation, the base is provided with a unified locking screw and a unified connecting frame. The unified connecting frame is divided into two types: an upper one and a lower one. The clamping part of the clamping and locking seal is connected to the lower unified connecting frame through a control part, and the clamping part is connected to the upper unified connecting frame through a control part. The unified locking screw controls the upper unified connecting frame and the lower unified connecting frame to move synchronously in opposite directions.

[0010] In one possible implementation, the clamping ring is further provided with a guide port for guiding the pressure-applying component. The guide port is a cylindrical limiting channel with a flared guide end.

[0011] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. According to the improved cable protection pipe provided by the embodiments of the present invention, the protection pipe is modularized and a corresponding docking mechanism is added to quickly assemble and connect the modular pipe bodies together, which effectively improves the efficiency and convenience of splicing the cable protection pipe. At the same time, the docking mechanism and the two assembled and connected modular pipe bodies are interconnected, which effectively improves the integrity of the three and is conducive to improving the reliability of the modular pipe body connection. In the process of assembling and connecting the modular pipe bodies, the pipe body unit is first automatically pre-sealed, and then a secondary seal is uniformly performed to ensure the sealing of the pipe body unit docking and the sealing of the pipe body unit connection, further improving the quality and reliability of the splicing of the connected protection pipe.

[0012] 2. According to an embodiment of the present invention, an improved cable protection pipe is provided in which the locking component first automatically limits the base frame and the base during the modular pipe connection process, and then further locks and fixes the base frame and the base. The whole process is simple and convenient, which not only improves the convenience and stability of the protection pipe connection, but also improves the integrity of the entire pipe splicing structure, and correspondingly improves the reliability of the modular pipe connection, and has the advantage of convenient disassembly and assembly.

[0013] 3. An improved cable protection pipe according to an embodiment of the present invention limits the limiting block by an accompanying limiting member, preventing the limiting block from moving abnormally during the locking process of the base frame and moving to a state aligned with the unlocking part, thereby improving the stability of the base frame and base locking and fixing state, and correspondingly improving the reliability of the modular pipe body connection.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 An improved cable protection pipe includes a modular pipe body 1 and a docking mechanism 2 for connecting two sets of modular pipe bodies 1 together. The modular pipe body 1 includes a base frame 101, on which several pipe body units 102 are disposed. The docking mechanism 2 includes a base 22 with several mating interfaces 21. The modular pipe bodies 1 are located on both sides of the base 22, and the mating interfaces 21 are located between the two mating pipe body units 102. Each of the two ports of the mating interface 21 is provided with a pressure sealing element 23 and a clamping locking sealing element 24. A pressure applying element 25 is provided on the base frame 101, and locking components 26 are symmetrically arranged between the base 22 and the base frame 101. Figure 2As shown, during the connection of the two sets of modular pipe bodies 1, the base frame 101 is moved towards the base 22 until the corresponding end of the pipe body unit 102 is inserted into the interface 21. During this process, the locking component 26 automatically limits the base frame 101 initially. Then, the locking component 26 further locks and fixes the base frame 101. During this process, the pressure applying component 25 automatically applies pressure to the pressing sealing component 23 to seal the pipe body unit 102. Finally, the locking component 26 further seals the pipe body unit 102, thus completing the connection of the two sets of modular pipe bodies 1. The entire connection process is fast, efficient, and convenient. At the same time, it ensures that the connected pipe body unit 102 has stable sealing performance, effectively improving the convenience and reliability of the cable protection pipe.

[0024] See Figure 2 and Figure 4 The locking component 26 includes a limiting sliding fastening seat 261 and a fastening member 262 corresponding to the fastening seat 261. The fastening seats 261 are symmetrically arranged on the base 22. The base 22 is provided with a control member 263 that controls the synchronous reverse sliding of the fastening seats 261. The fastening members 262 are respectively connected to the corresponding base frame 101. During the movement of the base frame 101 towards the base 22, the fastening members 262 automatically fasten with the fastening seat 261 as the base frame 101 moves towards the base 22. At this time, the pipe unit 102 has been initially inserted into the corresponding interface 21. Then, it is only necessary to control the synchronous relative movement of the fastening seat 261 through the control member 263 to further lock and fix the base frame 101 to complete the insertion of the pipe unit 102 and the initial sealing. The whole process is very convenient. The control member 263 is a bidirectional threaded rod.

[0025] See Figure 2 , Figure 4 and Figure 5 The fastener 262 includes a rotating post 2622 that is elastically connected to a limiting block 2621. The rotating post 2622 is rotatably connected to the base frame 101 through friction. The fastener seat 261 is a sliding seat 2612 with a limiting port 2611. The limiting port 2611 includes a cylindrical limiting portion, a flared guide portion, and an unlocking portion that penetrates the limiting portion and the guide portion. Figure 4As shown in the upper-middle view, the guide portion and the limiting portion in the limiting port 2611 on the right side of interface 21 are distributed sequentially from right to left. Under normal conditions, the limiting block 2621 and the unlocking portion are misaligned. During the connection process, the rotating column 2622 moves with the base frame 101 toward the base 22, first passing through the guide portion and then smoothly entering the limiting portion. During this process, the limiting block 2621 is subjected to force and slides inward toward the rotating column 2622. When the limiting block 2621 is no longer subjected to force after passing the limiting portion with the rotating column 2622, it automatically slides outward toward the rotating column 2622 under the action of elastic force and automatically locks onto the limiting port 2611 to initially limit the base frame 101. During the disassembly process, it is only necessary to rotate the rotating column 2622 to align the limiting block 2621 with the unlocking portion, and it can be smoothly moved out of the limiting port 2611 to complete the unlocking.

[0026] See Figure 4 and Figure 5 The base 22 is elastically limited and slidably equipped with an accompanying limiting element 264, such as... Figure 5 As shown, the accompanying limiting member 264 is an arc-shaped member with two limiting ends. The arc-shaped member is slidably connected to the base 22. During the process of the control member 263 controlling the buckle seat 261 to move synchronously relative to each other to further lock and fix the base frame 101, the limiting block 2621 moves with the buckle seat 261 and enters between the two limiting ends of the accompanying limiting member 264. The limiting ends limit the limiting block 2621, so that the limiting block 2621 and the limiting port 2611 are in a stable limiting state, avoiding the limiting block 2621 from moving abnormally during the locking process of the base frame 101 and moving to the state of aligning with the unlocking part. This improves the stability of the base frame 101 in the locking and fixing state. As the buckle seat 261 continues to move, the accompanying limiting member 264 moves accordingly with the buckle seat 261 while limiting the limiting block 2621.

[0027] See Figure 2 , Figure 5 , Figure 6 and Figure 7The compression sealing component 23 includes an annular sealing ring 231 and a corresponding compression ring 232. The clamping and locking sealing component 24 includes a clamping portion 242 with an arc-shaped sealing end 241 and a control portion 243 that is horizontally slidably connected to the clamping portion 242. The clamping portion 242 is symmetrically arranged and slidably connected to the compression ring 232 with upper and lower limits. The control portion 243 is slidably connected to the base 22. The clamping portion 242 moves with the compression ring 232, and after the compression ring 232 compresses the sealing ring 231, the control portion 243 compresses and seals the pipe unit 102 again, effectively improving the sealing performance of the pipe unit 102. The control portion 243 is a connection... The frame, base 22 is also provided with a unified locking screw 3 and a unified connecting frame 4. The unified connecting frame 4 is divided into two types: upward and downward. The clamping part 242 of the clamping and locking sealing part 24 is connected to the downward unified connecting frame 4 through the control part 243, while the clamping part 242 of the lower part is connected to the upward unified connecting frame 4 through the corresponding control part 243. Both the upward unified connecting frame 4 and the downward unified connecting frame 4 are threadedly connected to the unified locking screw 3. The unified locking screw 3 is a bidirectional threaded rod. Rotating the unified locking screw 3 synchronously drives the upward unified connecting frame 4 and the downward unified connecting frame 4 to slide synchronously in opposite directions in the vertical direction, thereby synchronously controlling the clamping part 242 to clamp and seal the pipe unit 102.

[0028] See Figure 2 , Figure 3 and Figure 6 The clamping ring 232 is also provided with a guide port 233 for guiding the pressure-applying component 25. The guide port 233 is a connecting block 2332 with a cylindrical limiting channel 2331. The connecting block 2332 is slidably connected to the base 22 and directly contacts the clamping ring 232, applying the pressure applied by the pressure-applying component 25 to the clamping ring 232. The end of the cylindrical limiting channel 2331 is flared. The guide port 233 guides the pressure-applying component 25 so that it can smoothly apply the pressure to the clamping ring 232.
