Description

Technical Field

[0001] This utility model relates to the field of cable protection device technology, and in particular to a connector for a cable protection tube. Background Technology

[0002] Power cables are of great strategic importance and their operational stability must be strictly guaranteed around the clock. However, due to harsh environments, power cables are often prone to breakage. Therefore, it is now necessary to install power cable protection pipes on the outside of power cables when laying them.

[0003] Power cable protection pipes need to have a certain degree of sealing; otherwise, the power cables still pose an uncontrollable potential risk of damage. Considering construction and transportation reasons, current power cable protection pipes are used in a segmented splicing manner. During splicing, connectors are required. For example, patent application CN219554511U describes a cable protection pipe with an end connector threaded to the inner wall of one end. The end connector includes a threaded interface and a first connecting plate. The threaded interface is threaded to the inner wall of the cable protection pipe, and the other end of the threaded interface is fixedly connected to the first connecting plate. Four pins at the four corners of the first connecting plate are used to connect connectors. The other end of each connector is also connected to a symmetrical end connector via pins. The end connectors are also threaded to the inner wall of another cable protection pipe. This invention uses pins for easy installation and disassembly to connect the connector to the cable protection pipe. After inserting the pin into the through hole between the two connecting plates, rotating the pin changes the locking strip from longitudinal to transverse for locking. This structure allows for quick and reliable connection of the cable protection pipe, preventing detachment and facilitating replacement.

[0004] However, when assembling the device, the user needs to rotate multiple pin fixing parts before the cable protection pipes can be spliced ​​together. This not only increases the number of operation steps but also reduces the efficiency of cable protection pipe installation.

[0005] Therefore, it is necessary to provide a connector for cable protection tubes to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a connector for cable protection pipes, which solves the problem that multiple pin fixing parts need to be rotated before cable protection pipes can be spliced ​​together, which not only increases the operation steps but also reduces the efficiency of cable protection pipe installation.

[0007] To solve the above-mentioned technical problems, this utility model provides a connector for a cable protection tube, comprising: A first connecting component and a second connecting component are disposed opposite to each other.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a connector for a cable protection tube provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the first and second connecting components. Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown.

[0019] A connector for a cable protection tube includes: a first connecting component 1 and a second connecting component 2, wherein the first connecting component 1 and the second connecting component 2 are disposed opposite to each other; The first connecting component 1 includes a first mounting plate 11, a first threaded ring 13 is fixedly mounted on one side of the first mounting plate 11, and snap-fit ​​grooves 12 are opened inside both ends of the first mounting plate 11. The second connecting assembly 2 includes a second mounting plate 21. A second threaded ring 22 is fixedly mounted on one side of the second mounting plate 21. Elastic plates 23 are fixedly mounted on both ends of the other side of the second mounting plate 21. A snap-fit ​​block 24 is fixedly mounted on one side of each of the two elastic plates 23. The two elastic plates 23 are respectively inserted into the inner side of the two snap-fit ​​grooves 12, and the two snap-fit ​​blocks 24 are respectively snapped into both ends of the other side of the second mounting plate 21.

[0020] A second sealing ring 5 is fixedly installed on the other side of the first mounting plate 11 and the other side of the second mounting plate 21, and one side of the two second sealing rings 5 ​​abuts against each other.

[0021] Both the first mounting plate 11 and the second mounting plate 21 are provided with a plurality of limiting components 3. Each of the plurality of limiting components 3 includes a limiting groove 31 and a limiting rod 32. The limiting groove 31 is opened inside the first mounting plate 11, and the limiting rod 32 is fixedly installed on the other side of the second mounting plate 21. The limiting rod 32 is inserted into the inner side of the limiting groove 31.

[0022] The outer surfaces of the first threaded ring 13 and the second threaded ring 22 are both threaded with cable protection tubes 6.

[0023] The outer surfaces of the first threaded ring 13 and the second threaded ring 22 are both fitted with a first sealing ring 4.

[0024] The first mounting plate 11 and the second sealing ring 5 on the other side of the second mounting plate 21 abut against each other to form a second seal, further preventing moisture and impurities from entering. The limiting rod 32 on the second mounting plate 21 is inserted into the limiting groove 31 of the first mounting plate 11 to ensure that the two connecting components are precisely aligned during splicing, and to avoid sealing failure or structural loosening due to misalignment. Both the first sealing ring 4 and the second sealing ring 5 are made of weather-resistant rubber. After the first mounting plate 11 and the second mounting plate 21 are installed, they can compress the second sealing ring 5 to form a sealing effect.

[0025] The working principle of the connector for the cable protection tube provided by this utility model is as follows: First, the two cable protection pipes 6 are threadedly connected to the first threaded ring 13 of the first connecting component 1 and the second threaded ring 22 of the second connecting component 2, respectively. During the tightening process, the first sealing ring 4 on the outer side of the first threaded ring 13 and the second threaded ring 22 is squeezed by one end of the cable protection pipe 6 to form the first seal. Next, align the elastic plate 23 of the second connecting component 2 with the snap-fit ​​groove 12 of the first connecting component 1, and push the second mounting plate 21 toward the first mounting plate 11. The elastic plate 23 is slightly deformed by the pressure of the inner wall of the snap-fit ​​groove 12 and is smoothly inserted into the snap-fit ​​groove 12. When the snap-fit ​​block 24 moves to the outside of the snap-fit ​​groove 12, the elastic plate 23 is reset, and the snap-fit ​​block 24 is snapped onto the other side of the first mounting plate 11, completing the quick fixation of the first connecting component 1 and the second connecting component 2. No need to rotate any pins, the operation only requires a single insertion, which greatly shortens the splicing time. To disassemble, simply press the two snap-fit ​​blocks 24 inwards to deform the elastic plate 23 and disengage it from the snap-fit ​​groove 12. This will separate the first connecting component 1 and the second connecting component 2. The operation is convenient and facilitates later maintenance or replacement of the cable protection tube 6.

[0026] Compared with related technologies, the connector for a cable protection tube provided by this utility model has the following advantages: With the setup of the first connecting component 1 and the second connecting component 2, when splicing the cable protection pipe 6, it is only necessary to first thread the two sections of cable protection pipe 6 to the first threaded ring 13 and the second threaded ring 22 respectively, and then insert the elastic plate 23 of the second connecting component 2 into the snap-fit ​​groove 12 of the first connecting component 1. After the elastic plate 23 deforms and resets, the snap-fit ​​block 24 can automatically snap into the other side of the first mounting plate 11 to complete the fixation. The whole process does not require rotating multiple pin fixing parts as in existing devices, making the operation convenient and quick, and improving the efficiency of cable protection pipe 6 installation.

[0027] Second Embodiment Please refer to the following: Figure 4 and Figure 5 Based on the connector for a cable protection tube provided in the first embodiment of this application, the second embodiment of this application proposes another connector for a cable protection tube. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0028] Specifically, the second embodiment of this application provides a cable protection tube connector that differs in that both ends of the first mounting plate 11 are provided with protective components 7.

[0029] Both of the protective components 7 include a rotating seat 71, which is fixedly installed on one side of the first mounting plate 11. A rotating rod 72 is fixedly installed inside the rotating seat 71. A rotating block 74 is rotatably connected to the outer side of the rotating rod 72. A protective cover 75 is fixedly installed on one side of the rotating block 74. The protective cover 75 is sleeved on the outer side of the snap-fit ​​block 24. Torsion springs 73 are fixedly installed at the top and bottom of the rotating block 74. One end of each of the two torsion springs 73 is fixedly installed on the outer side of the rotating rod 72.

[0030] When in use, the elasticity of the torsion spring 73 always drives the protective cover 75 to rotate towards the outer side of the snap-fit ​​block 24, so that the protective cover 75 covers the outer side of the snap-fit ​​block 24. The automatic reset function of the protective cover 75 does not require manual intervention, further simplifying the operation.

[0031] The working principle of the connector for the cable protection tube provided by this utility model is as follows: After the first connecting component 1 and the second connecting component 2 are spliced ​​together, the protective cover 75 of the protective component 7 automatically rotates around the rotating rod 72 to the outside of the snap-fit ​​block 24 under the elastic action of the torsion spring 73, completely covering the snap-fit ​​part between the snap-fit ​​block 24 and the elastic plate 23, forming physical protection, and preventing the snap-fit ​​block 24 from falling off due to tool collisions or external pressure during construction. When it is necessary to disassemble the connector, rotate the protective cover 75 outward to drive the rotating block 74 to compress the torsion spring 73, exposing the snap-fit ​​block 24. Then press the snap-fit ​​block 24 to separate the connector. After disassembly, release the protective cover 75, and the torsion spring 73 will reset and drive the protective cover 75 back to its initial protective position. No additional fixing is required, and the operation is convenient.

[0032] Compared with related technologies, the connector for a cable protection tube provided by this utility model has the following advantages: By setting up the protective component 7, the problem of the snap-fit ​​block 24 falling off due to external impact can be avoided during use, thereby improving the anti-interference capability of the overall connector structure, which is especially suitable for complex outdoor construction environments.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
