Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically to a cable protection pipe that is easy to install. Background Technology

[0002] Cable protection pipes are conduits used to protect cables, and they are typically made of plastic materials (such as PVC pipes and PE pipes). Cable protection pipes possess a certain level of mechanical strength and corrosion resistance, providing physical protection for cables and preventing damage from external factors.

[0003] When installing cable protection conduits, one end of one conduit is first inserted into the socket of the other conduit and then secured with bolts and nuts, ensuring a stable connection and good sealing between the two conduits. However, when installing two conduits together, angular misalignment and positional changes can easily occur, making installation inconvenient. Therefore, we propose a cable protection conduit that is easier to install. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] This utility model provides a technical solution: such as Figure 1 - Figure 5 The cable protection pipe shown includes a pipe body 1. A sealing ring 13 is fixedly connected to the rear end of the pipe body 1. An annular plate 2 is fixedly connected to the rear edge of the sealing ring 13. A splicing ring 3 is fixedly sleeved on the rear edge of the outer wall of the annular plate 2. Four mounting holes 4 are arranged in a circular array around the front end of the splicing ring 3. Four positioning grooves 15 are arranged in a circular array around the center of the inner surface of the annular plate 2. A splicing ring 5 is fixedly sleeved on the outer wall of the pipe body 1 near the front edge. Four mounting holes 7 are arranged in a circular array around the front edge of the splicing ring 5. The four mounting holes 7 correspond to the positions of the four mounting holes 4. Four positioning blocks 8 are fixedly connected in a circular array around the center of the outer wall of the pipe body 1. The four positioning blocks 8 correspond to the positions of the four positioning grooves 15. Each of the four positioning blocks 8 has a retaining mechanism at the end away from the pipe body 1.

[0020] The securing mechanism includes a cylindrical groove 11, which is located at the middle of the end of the positioning block 8 away from the tube body 1. A pin 9 is slidably attached to the inner wall of the cylindrical groove 11. One end of the pin 9 located on the outer side of the cylindrical groove 11 is hemispherical, and a spring 12 is fixedly connected between the other end of the pin 9 and the inner circular surface of the cylindrical groove 11.

[0021] Each of the four positioning slots 15 has an arc-shaped groove 16 in the middle of the wall surface away from the center point of the annular plate 2, and the four arc-shaped grooves 16 correspond to the positions of the four pins 9 respectively.

[0022] A sealing ring 6 is fixedly connected to the middle of the front end of the splicing ring 2 5. The front end of the sealing ring 6 is set at an inclined angle. An annular groove 17 is opened in the middle of the rear end of the splicing ring 3. The annular groove 17 and the sealing ring 6 are positioned and matched in shape.

[0023] A sealing ring 10 is fixedly connected to the front end of the tube body 1. An annular groove 14 is provided at the front end of the sealing ring 13. The annular groove 14 and the sealing ring 10 are positioned and fit each other in shape.

[0024] The annular plate 2 and the sealing ring 13 are integrally formed; specifically, the annular plate 2 and the sealing ring 13 have good stability.

[0025] Working principle: When two tubes 1 need to be installed together, first place the two tubes 1 in a corresponding position, and align the front end of the rear tube 1 with the rear end of the front tube 1 (for ease of explanation, the front tube 1 is referred to as "tube 1A" and the rear tube 1 is referred to as "tube 1B"). Then adjust the angle between tube 1A and tube 1B so that the four positioning blocks 8 on tube 1B correspond to the four positioning grooves 15 on the annular plate 2 on tube 1A.

[0026] Then, tube body 1B is inserted into the annular plate 2 on the sealing ring 13 of tube body 1A. During this process, tube body 1B will slide towards tube body 1A within the annular plate 2 on tube body 1A, and the four positioning blocks 8 on tube body 1B will also slide towards tube body 1A within their respective positioning grooves 15 on tube body 1A. At this time, the pins 9 on each of the four positioning blocks 8 will slide within the cylindrical grooves 11 on their respective positioning blocks 8 due to the obstruction of their respective positioning grooves 15 (at the same time, the springs 12 between the four pins 9 and their respective cylindrical grooves 11 will be compressed). When the four positioning blocks 8 are fully engaged with their respective positioning grooves 15, under the force of the four springs 12, the four pins 9 will automatically reset and insert into the arc grooves 16 on their respective positioning grooves 15, thereby achieving the initial fixation of tube body 1A and tube body 1B.

[0027] It should be noted that when tube body 1B is inserted into the annular plate 2 on the sealing ring 13 on tube body 1A, the sealing ring 2 10 on tube body 1B will be tightly inserted into the annular groove 14 on the sealing ring 13 on tube body 1A, thereby achieving a sealing effect. In addition, the sealing ring 6 on the splicing ring 2 5 on tube body 1B will also be tightly inserted into the annular groove 17 on the splicing ring 3 on tube body 1A, achieving a double seal and further ensuring the sealing effect.

[0028] At this point, the four mounting holes 7 on the splicing ring 25 on pipe body 1B will correspond to and approach the corresponding mounting holes 4 on the splicing ring 3 on pipe body 1A. Finally, the four bolts are inserted into the corresponding mounting holes 7 of the four mounting holes 4 on the front and back, and the four nuts are tightened on the four bolts, thereby achieving the locking and fixing between the splicing ring 3 on pipe body 1A and the splicing ring 25 on pipe body 1B. Thus, the pipe body 1A and pipe body 1B can be firmly installed.

[0029] It should be noted that the cooperation of the four positioning blocks 8 with the four positioning slots 15 respectively avoids the angular displacement between pipe body 1A and pipe body 1B, which facilitates the installation of pipe body 1A and pipe body 1B. Furthermore, the cooperation of the four pins 9 with the four positioning slots 15 respectively restricts the front-to-back displacement between pipe body 1A and pipe body 1B to a certain extent, further facilitating the installation of pipe body 1A and pipe body 1B.

[0030] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
