[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: A mine explosion-proof switch electrical cabinet device includes a cabinet body 1. First, place the cabinet body 1 in a suitable position. A connecting seat 2 is fixedly connected to the top of the cabinet body 1. Install the connecting seat 2 with an external connecting device. When in use, when the outside of the cabinet body 1 collides, the cabinet body 1 will shake. A plurality of fixed rods 3 are fixedly connected to both the left and right sides inside the cabinet body 1. A protection box 4 is slidably connected to the outside of the plurality of fixed rods 3. Place electronic devices inside the protection box 4. A plurality of limiting components are arranged on the outside of both the left and right sides of the protection box 4. The protection box 4 will also shake, and the limiting components can limit the protection box 4.

[0032] The limiting component includes a telescopic rod 5. One side of the outside of the telescopic rod 5 is fixedly connected to one side of the inside of the cabinet 1. The fixed rod 3 and the telescopic rod 5 move simultaneously. The other side of the telescopic rod 5 is fixedly connected to one side of the outside of the protection box 4. A plurality of dampers 6 are fixedly connected to both the left and right sides of the outside of the protection box 4. The dampers 6 absorb the impact force outside the cabinet 1. A spring 7 is sleeved outside the damper 6. One end of the spring 7 is fixedly connected to one side of the inside of the cabinet 1, and the other end of the spring 7 is fixedly connected to one side of the outside of the protection box 4. At the same time, the spring 7 will also be compressed by force and absorb the external impact force due to its own elastic characteristics. A limiting plate 8 is fixedly connected to the outside of the fixed rod 3. The outside of the limiting plate 8 is in contact with the inner wall of the protection box 4. The limiting plate 8 can limit the fixed rod 3 to prevent it from separating from the protection box 4 during sliding. Thus, the buffer can be increased to offset the impact force, the electronic devices inside the protection box 4 can be prevented from being damaged, and the protection box 4 can be protected;

[0033] Refer to Figure 3 - Figure 4 , a sealing plate 12 is slidably connected to the front end of the protection box 4. The sealing plate 12 is placed through the outside of the extension column 9 to the front end of the protection box 4. Fixed components are fixedly connected to the four corners of the front end of the protection box 4. The fixed components can fix the sealing plate 12. The fixed components include an extension column 9. The outside of the extension column 9 is fixedly connected to the inside of the protection box 4. A fixed column 10 is fixedly connected to the inside of the extension column 9. A resilient plate 11 is fixedly connected to the front end of the fixed column 10. A positioning column 13 is slidably connected to the inner wall of the resilient plate 11. The positioning column 13 is inserted into the inside of the resilient plate 11. The outside of the resilient plate 11 is in contact with the inner wall of the extension column 9. A locking collar 14 is threadedly connected to the outside of the extension column 9. The locking collar 14 is sleeved on the outside of the extension column 9 and screwed backward.

[0034] As the locking collar 14 moves backward continuously, the outside of the positioning column 13 is slidably connected to the inner wall of the locking collar 14. The inner wall of the locking collar 14 is in contact with the outside of the resilient plate 11, which will squeeze the resilient plate 11. The inner wall of the locking collar 14 is threadedly connected to the outside of the extension column 9. At this time, the distance between the resilient plate 11 and the positioning column 13 is reduced, and the sealing plate 12 can be fixed to the front end of the protection box 4, realizing the fixation of the sealing plate 12 outside the protection box 4, ensuring the sealing performance of the protection box 4. A cabinet door 15 is rotatably connected to the front end of the cabinet 1. The cabinet door 15 is closed. An observation window 16 is fixedly connected to the front end of the cabinet door 15. The staff can observe the situation inside the cabinet 1 through the observation window 16.

[0035] Working principle: First, place the cabinet body 1 in a suitable position, then install the connecting seat 2 with an external connecting device, then place the electronic components inside the protective box 4, then pass the sealing plate 12 through the outside of the extension column 9 and place it at the front end of the protective box 4, then insert the positioning column 13 into the elastic plate 11, and then put the locking collar 14 on the outside of the extension column 9 and tighten it backward. As the locking collar 14 moves backward continuously, it will squeeze the elastic plate 11. At this time, the distance between the elastic plate 11 and the positioning column 13 shrinks, and the sealing plate 12 can be fixed at the front end of the protective box 4. Then close the cabinet door 15, and the staff can observe the situation inside the cabinet body 1 through the observation window 16.

[0036] During use, when the outside of the cabinet body 1 is collided, the cabinet body 1 will shake, and at the same time, the protective box 4 will also shake. At this time, the fixed rod 3 and the telescopic rod 5 move simultaneously, and the damper 6 absorbs the impact force from the outside of the cabinet body 1. At the same time, the spring 7 will also be compressed by the force and absorb the external impact force due to its own elastic characteristics. Thus, the buffer can be increased to offset the impact force, and the electronic components inside the protective box 4 can be prevented from being damaged.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
