Description

Technical Field

[0001] This utility model belongs to the field of broadcasting and television engineering technology, and specifically relates to a new type of junction box for broadcasting and television engineering. Background Technology

[0002] In the field of broadcasting and television engineering, junction boxes are commonly used. They are mostly made of metal and have multiple cables running inside. Multiple incoming lines can be gathered together and then run out in batches, which facilitates the centralized management of multiple cables and further wiring connections. They play an increasingly important role in the field of broadcasting and television engineering and other related fields.

[0003] Existing junction boxes have the following problems when in use: cables pass through the junction box and are fixedly connected to the fixed structure inside the junction box, which prevents the cables from moving left and right. When the cables are subjected to external pulling force, the fixed cables cannot move left and right to provide elastic buffering, which makes the cables easy to be pulled directly and thus affects the safe and stable use of the cables and reduces the performance. Therefore, it is necessary to carry out further innovative design. Utility Model Content

Guide holes 14 are provided inside the left and right sides of the rear end of the top seat 12, and the guide holes 14 are slidably connected to the guide shafts 10. A rotating groove 15 is provided inside the rear end of the top seat 12. An I-shaped shaft 16 is rotatably connected inside the rotating groove 15. A screw shaft 17 is fixedly connected to the bottom end of the I-shaped shaft 16, and the screw shaft 17 is screwed into the screw hole 11. A knob 18 is fixedly connected to the upper end of the screw shaft 17. A bottom clamping pad 9 is fixedly connected to the upper end of the base 8. A knob 18 is fixedly connected to the bottom end of the top seat 12.

The cable is placed between the base 8 and the top seat 12, and then the knob 18 drives the I-shaped shaft 16 and the screw shaft 17 to rotate. The guide hole 14 slides relative to the guide shaft 10 for guidance and limitation. By continuously tightening the screw shaft 17 and the screw hole 11, the top seat 12 can be moved down to achieve the clamping and fixing of the cable. Reverse rotation of the knob 18, the I-shaped shaft 16, and the screw shaft 17 can drive the top seat 12 to move up to release the cable from the fixed state so that the cable can be further removed. The bottom clamping pad 9 and the top clamping pad 13 can further improve the anti-slip clamping effect of the cable.

[0017] In this embodiment: When in use, the present invention can fix the cable passing through the box 1 inside the box 1 by setting and cooperating the base 8, guide shaft 10, screw hole 11, top seat 12, guide hole 14, rotating groove 15, I-shaped shaft 16, screw shaft 17, and knob 18 located on the rail frame 3 inside the box 1. It is simple and convenient, and can be used to fix cables of various diameters. It is of better quality.

[0018] Furthermore, refer to Figure 4 , Figure 6 and Figure 7 As shown, several rail frames 3 are fixedly connected to the bottom of the inner part of the box 1. The upper end of the rail frame 3 is provided with a guide groove 4. A slide block 5 is slidably connected to the middle position of the inner part of the rail frame 3. Springs 6 are fixedly connected to both the left and right ends of the slide block 5. The end of the spring 6 away from the slide block 5 is fixedly connected to the rail frame 3. A guide block 7 is fixedly connected to the upper end of the slide block 5. The guide block 7 is slidably connected to the guide groove 4. The upper end of the guide block 7 is fixedly connected to the base 8. The slide block 5 can slide in the rail frame 3 and is guided by the guide block 7 sliding in the guide groove 4. The sliding of the slide block in the rail frame 3 can further drive the spring 6 to move elastically.

[0019] In this implementation plan: When the fixed cable is subjected to external pulling force, the cable can move left and right for elastic buffering through the arrangement and cooperation of the rail frame 3, guide groove 4, slide 5, spring 6 and guide block 7. This can greatly reduce the damage caused to the cable by external pulling force and prevent the cable from being directly pulled off, so as to ensure the safe use of the cable and make it better.

[0020] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a lid 21 is provided at the upper end of the box body 1.
