DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 in 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.

[0017] Please refer to Figures 1-4, the utility model provides a technical solution: a compressed air device with dust and explosion prevention functions underground, including a box body 1, a box door 2 is slidably connected to the box body 1, a rubber pad 3 is provided on the box door 2, and symmetrically arranged rotating rods 4 are rotatably connected to the box door 2. A plurality of sliding grooves 5 arranged in an array are opened on both of the two rotating rods 4. A moving block 6 is slidably connected to the inside of each of the plurality of sliding grooves 5. The plurality of moving blocks 6 are respectively fixedly connected to form a rotating ring 7. A clamping plate 8 is fixedly connected to the far side of each of the two rotating rings 7. One end of each of the two rotating rods 4 is fixedly connected to a square rod 9. An installation block 10 is slidably connected to each of the two square rods 9. Symmetrically arranged limiting rods 11 are fixedly connected to each of the two installation blocks 10. A spring 12 is fixedly connected to each of the two installation blocks 10 at a position corresponding to the square rod 9. Limiting grooves 13 arranged symmetrically are opened inside the box body 1.

[0018] One end of each of the rotating rods 4 rotatably penetrates the box door 2 and is fixedly connected to the square rod 9. The square rod 9 is convenient for driving the installation block 10 to rotate. The limiting rods 11 are all slidably connected to the inside of the limiting grooves 13. The connection between the limiting rods 11 and the limiting grooves 13 is convenient for fixing the position of the installation block 10. Accommodating grooves 14 arranged symmetrically are opened on the rubber pad 3. Card slots 15 are opened at positions corresponding to the accommodating grooves 14 on the rubber pad 3. The clamping plates 8 are all movably connected to the inside of the card slots 15. The accommodating grooves 14 are convenient for accommodating the rotating ring 7. The connection between the clamping plate 8 and the card slot 15 can prevent the rotating ring 7 from rotating. The square rods 9 are all located in the hollow positions of the springs 12.

[0019] Specifically, when using the utility model, when the box door 2 is impacted, the first to bear the impact is the rubber pad 3. The rubber pad 3 can prevent the explosive from directly hitting the box door 2 and can provide the first layer of protection for the box door 2. When the rubber pad 3 is impacted, it will transfer the impact force to the box door 2. At this time, the box door 2 will move towards the inside of the box body 1. The box door 2 will drive the two rotating rods 4 and the square rod 9 to move together. The positions of the mounting block 10 and the limiting rod 11 remain unchanged because at this time the limiting rod 11 is connected inside the limiting groove 13. The mounting block 10 with the unchanged position at this time will guide the movement of the square rod 9. At the same time, since the position of the mounting block 10 is fixed at this time, the movement of the box door 2 will also compress and contract the spring 12. The process of the spring 12 contracting is the process of absorbing and resolving the impact force of the box door 2. When the spring 12 contracts to the limit, it will drive the box door 2 to reset to its original position. This process can resolve the impact force borne by the box door 2 to the greatest extent. The box door 2 can also block dust for the face mask inside the box body 1, prevent the face mask from being affected by dust and becoming unusable, and at the same time extend the service life of the box door 2. When the entire compressed air device needs to be used, the two rotating rings 7 can be directly pulled in the opposite direction of the box body 1. The rotating ring 7 will drive the moving block 6 and the clamping plate 8 to move together. The sliding of the moving block 6 in the sliding groove 5 can guide the movement of the rotating ring 7. The movement of the clamping plate 8 will separate from the clamping groove 15. At this time, the two rotating rods 4 can be rotated through the rotating ring 7. Both of the two rotating rods 4 will drive the mounting block 10 to rotate through the square rod 9. The mounting block 10 will drive the limiting rod 11 to rotate. The rotation of the limiting rod 11 will separate from the limiting groove 13. At this time, the staff can remove the box door 2, then take out the breathing mask, make the breathing mask completely cover the mouth and nose, then pull out the bolt, find the air inlet valve inside the box body 1 and open it, observe the pressure indication to ensure that the air path is unobstructed, and then breathe naturally.

[0020] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
