The fixed column 7 can ensure the stability of the shape of the spring 9 after deformation. The spring 9 can connect the slip rings 8. A damper 10 is arranged inside the spring 9. The inner parts of the two slip rings 8 are slidably connected to the outside of the fixed column 7. The two ends of the damper 10 are fixedly connected to the outside of the fixed column 7. The damper 10 reduces the amplitude and duration of the vibration by consuming vibration energy, and can improve the service life of the spring 9 and reduce the cost. The fixed column 7 can ensure the stability of the damper 10. The tops of the two slip rings 8 are rotatably connected with connecting rods 11. The tops of the two connecting rods 11 are rotatably connected with support plates 12. The outside of the support plate 12 is fixedly connected with a rain cover 13. The support plate 12 supports the rain cover 13, and the slip ring 8 and the rain cover 13 are connected by the connecting rod 11, so that the rain cover 13 can achieve force unloading and shock absorption.

[0027] A telescopic rod 14 is fixedly connected to the bottom of the support plate 12, and a spring 2 15 is sleeved on the outside of the telescopic rod 14. One end of the spring 2 15 is fixedly connected to the bottom of the support plate 12, and the other end of the spring 2 15 is fixedly connected to the top of the ring network cabinet 2. The telescopic rod 14 can improve the stability of the support plate 12, and the spring 2 15 can further achieve secondary force unloading, so that the overall structural performance is more stable. A moving plate 16 is fixedly connected to the inner wall of the rear end of the ring network cabinet 2, and the ring network cabinet 2 fixes the moving plate 16. The inner wall of the moving plate 16 is slidably connected to a wiring harness assembly, and the top of the wiring harness assembly is fixedly connected to an adjustment assembly.

[0028] Reference Figure 4-Figure 5 The wiring harness assembly includes a slide plate 17, and a plurality of telescopic rods 18 are fixedly connected to the inside of the slide plate 17. The outside of the plurality of telescopic rods 18 is sleeved with springs 3 19. The adjacent sides of the plurality of telescopic rods 18 are fixedly connected with two clamping blocks 20. The telescopic rods 18 connect the clamping blocks 20 to the slide plate 17, and at the same time relieve the springs 3 19 and the clamping blocks 20 from such excessive external stress, thereby protecting the connecting parts from damage. One end of the plurality of springs 3 19 is fixedly connected to the inside of the slide plate 17, and the other end of the plurality of springs 3 19 is fixedly connected to the outside of the clamping blocks 20. The springs 3 19 can provide a rebound force to improve the clamping effect of the clamping blocks 20, and at the same time play a buffering role to improve the structural stability.

[0029] The adjustment component includes two stabilizing plates 21, and a pressure plate 22 is rotatably connected to one side of the two stabilizing plates 21. The stabilizing plate 21 ensures the stability of the pressure plate 22. The internal rotation of the pressure plate 22 is connected to a clamping column 23. The pressure plate 22 can store the clamping column 23. The outside of the clamping column 23 is slidably connected to the inner wall of the moving plate 16 and engaged with the through hole thereof. The position of the overall wiring harness device is adjusted and then fixed by engaging the clamping column 23 with the moving plate 16. The bottom of the pressure plate 22 is in contact with the top of the moving plate 16, and a spring four 24 is fixedly connected to the bottom of the front end of the pressure plate 22. The spring four 24 itself will cause the clamping column 23 to be tightly clamped in the opening of the moving plate 16 under its own rebound force.

[0030] Working principle: When the ring network cabinet 2 is placed outdoors, it will be affected by the external environment, so that the inside will be damp and affect normal operation. Installing a dehumidifier 4 inside can remove internal moisture and ensure internal dryness. When it encounters severe weather such as heavy rain and strong wind, pressure will be applied to the rain cover 13 on the top. At this time, the rain cover 13 will transfer force to the support plate 12, so that the telescopic rod 14 moves downward as a whole, thereby moving the connecting rod 11 downward. At this time, the connecting rod 11 will input force to the slip ring 8, realize the mutual movement between the two slip rings 8, and transfer the impact energy to the spring 9, squeeze the spring 9, and the spring 9 will absorb the impact energy and convert it into elastic potential energy, which helps to reduce the influence of vibration and impact force, improve the structural stability, and greatly improve the external rainproof effect.

[0031] When the ring network cabinet 2 is built as a whole, it is necessary to connect the wires. In order to avoid safety accidents caused by cable crossing and scattered placement, the cables need to be fixed and the cables are embedded in the two clamping blocks 20. The cables will apply pressure to the outside. At this time, the clamping block 20 will be squeezed on the telescopic rod 2 18 and the spring 3 19 by the force. The spring 3 19 absorbs the pressure and generates its own rebound force under the action of the force, making the clamping block 20 clamp the cable more tightly. At the same time, in order to facilitate the staff to fix the cables, the sliding plate 17 can be slid to drive the overall cable bundling device to move. When it moves to the specified position, the pressing plate 22 is pressed, and the pressing plate 22 squeezes the spring 4 24, and at the same time, the card column 23 embedded in the pressing plate 22 is turned out, and the pressing plate 22 is released. Under the action of the rebound force of the spring 4 24, the card column 23 is driven to slide into the opening of the moving plate 16 to fix the sliding plate 17. In this way, the cable can be fixed at three points, and there is no need for too many cable bundling devices, thereby greatly improving the cable bundling efficiency and reducing the production cost.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
