Description

Technical Field

[0001] This utility model relates to the field of cable distribution boxes, and more particularly to a cable distribution box for rail transit. Background Technology

[0002] Cable distribution boxes are crucial equipment in rail transit systems for distributing, connecting, and managing cables. Typically installed in stations and depots, they contain multiple terminals and distribution devices. They distribute electrical energy or signals from the main cable to different branch cables, providing power and signal transmission channels for various rail transit equipment such as signal lights, communication equipment, and power supply equipment. Simultaneously, cable distribution boxes also protect cables from external interference, contributing to the rationality of cable layout and operational reliability within the rail transit system, ensuring the stable operation of the entire system.

[0003] However, current cable distribution boxes have the following shortcomings: Cable organization deficiencies: Current cable distribution boxes lack effective cable management methods, resulting in cables piling up haphazardly and becoming tangled. This is not only unsightly but also makes it difficult for maintenance personnel to quickly identify the cable routes and uses, greatly increasing the difficulty and time cost of subsequent maintenance. Disassembly convenience deficiencies: Existing cable distribution boxes are structurally unfavorable for disassembly, potentially employing too many complex fixing methods and connecting components. Disassembly requires numerous tools and involves cumbersome steps. In emergency repair situations, they cannot be quickly removed, affecting the repair progress and reducing work efficiency.

[0004] In response to this technical problem, this application proposes a cable distribution box for rail transit. Utility Model Content

[0023] 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.

[0024] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a cable distribution box for rail transit, comprising a base plate 1, a box body 2 disposed on the top side of the base plate 1, metal plates 5 fixedly connected to the four corners of the box body 2, a rotating rod 10 rotatably connected inside the box body 2, and a disc 8 fixedly connected to the top of the rotating rod 10. The rotating rod 10 allows cables to be wound around it for cable management, preventing cables from becoming too tangled and affecting subsequent maintenance. The disc 8 prevents cables from falling off the rotating rod 10. A box cover 6 is rotatably connected to the top side of the box body 2 via a hinge, sealing the box body 2 to prevent dirt from entering and damaging the cables. The four corners of the top side of the base plate 1 are fixedly connected... A fixing block 4 is fixedly connected, and a snap-fit ​​block 3 is rotatably connected to the top side of the fixing block 4. The bottom side of the snap-fit ​​block 3 abuts against the top side of the metal plate 5. By abutting the bottom side of the snap-fit ​​block 3 against the top side of the metal plate 5, the metal plate 5 is restricted between the snap-fit ​​block 3 and the fixing block 4. A plug rod 14 is fixedly connected to the bottom side of the snap-fit ​​block 3, and a snap-fit ​​ring 15 is fixedly connected to the outer wall of the plug rod 14. A slot is opened on the top side of the fixing block 4. The plug rod 14 is inserted into the slot, and the snap-fit ​​ring 15 is engaged in the slot. By inserting the plug rod 14 into the slot, the snap-fit ​​ring 15 is engaged in the slot, thereby connecting the snap-fit ​​block 3 and the fixing block 4 together, and thus fixing the metal plate 5 between the snap-fit ​​block 3 and the fixing block 4.

[0025] Reference Figure 2 and Figure 3 Four fixing plates 9 are fixedly connected to the inner wall of the housing 2. Positioning rods 11 are slidably connected inside the fixing plates 9. Multiple positioning slots are opened on the top side of the disc 8. The positioning rods 11 are inserted into the positioning slots. By inserting the positioning rods 11 into the positioning slots, the disc 8 is fixed, preventing the rotating rod 10 from rotating and causing the cable to loosen. The positioning rods 11 are threadedly connected to the threaded rods 12. The top side of the fixing plates 9 is rotatably connected to the handle 13 through a damping shaft. The top end of the threaded rod 12 is rotatably connected to the fixing plates 9. Inside the housing 2, the top end of the threaded rod 12 is fixedly connected to the inside of the rotating handle 13. The rotating handle 13 causes the threaded rod 12 to rotate, thereby driving the positioning rod 11 to insert into or dislodge from the positioning groove. The outer wall of the housing 2 is provided with multiple wire holes 17, through which cables can enter and exit the housing 2. The inner wall of the housing 2 is fixedly connected with multiple sealing rings 16 for sealing the wire holes 17. The top side of the inner wall of the housing 2 is fixedly connected with a sealing ring 7 for sealing the gap between the housing 2 and the cover 6.

[0026] Working principle: First, fix the base plate 1 to the wall in the track. Then, place the metal plate 5 on the housing 2 onto the fixing block 4. Then, rotate the buckle block 3 to rotate it onto the fixing block 4, so that the insert rod 14 is inserted into the slot and the buckle ring 15 is engaged in the slot, thereby connecting the buckle block 3 and the fixing block 4 together. Then, fix the metal plate 5 between the buckle block 3 and the fixing block 4, thus completing the installation of the housing 2. Then, wrap the cable around the rotating rod 10, and then rotate the rotating handle 13 to rotate the threaded rod 12, so that the threaded rod 12 drives the positioning rod 11 to slide, thereby inserting the positioning rod 11 into the positioning groove, thereby fixing the disc 8 and preventing the rotating rod 10 from rotating and causing the cable to loosen. Then, pass the end of the cable through the cable hole 17 out of the housing 2 to extend the cable to other places where it is needed. Then, close the cover 6 to seal the housing 2 to prevent dirt from entering and damaging the cable.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
