[0023] L-shaped limiting rods 111 are provided at the four corners inside the protection box 1 , and the four corners of the bottom plate 11 are movably inserted on the four limiting rods 111 .

[0024] By adopting the above technical solution, the limiting rod 111 can make the bottom plate 11 move up and down stably.

[0025] The two first rotating shafts 16 are located at one end of the outer wall of the protection box 1 and are jointly driven by a first belt 19 .

[0026] By adopting the above technical solution, the first belt 19 can make the two second rotating shafts 17 rotate synchronously, thereby reducing the installation of electrical equipment and lowering costs.

[0027] One of the first rotating shafts 16 is located at one end of the outer wall of the protection box 1 and is coaxially fixedly mounted with a driving motor 191 .

[0028] By adopting the above technical solution, the driving motor 191 provides power for the operation of the device.

[0029] Two symmetrically distributed fixed blocks 21 are fixed to one end of the outer wall of the protective box 1 that rotates close to the protective cover 2. A rotating rod 22 is rotatably provided on the opposite side of the two fixed blocks 21. An L-shaped connecting plate 23 is fixed on the rotating rod 22. The end of the connecting plate 23 away from the rotating rod 22 is fixed on the protective cover 2. A connecting shaft 24 is fixed to one end of the rotating rod 22. A connecting component is provided between the connecting shaft 24 and the second rotating shaft 17 away from the driving motor 191.

[0030] By adopting the above technical solution, the protective cover 2 is convenient for sealing the protective box 1 as a whole, and the inflator body 12 is fully protected.

[0031] The connecting assembly includes a transmission shaft 25, which is arranged between two connecting shafts 24. Second bevel gears 26 are fixedly provided at both ends of the transmission shaft 25. A third bevel gear 27 meshingly connected to the second bevel gear 26 is fixedly provided at one end of the connecting shaft 24 close to the transmission shaft 25. A second belt 28 is provided for transmission between the transmission shaft 25 and the second rotating shaft 17 away from the driving motor 191.

[0032] By adopting the above technical solution, the second belt 28 can drive the transmission shaft 25 to rotate while the second rotating shaft 17 is working, thereby increasing the linkage of the device.

[0033] The two second bevel gears 26 are arranged facing away from each other.

[0034] By adopting the above technical solution, the two second bevel gears 26 are arranged in opposite directions so that the two third bevel gears 27 can rotate in the same direction or in opposite directions at the same time.

[0035] Handles 3 are fixedly provided on two opposite sides of the outer wall of the protection box 1 .

[0036] By adopting the above technical solution, the handle 3 makes it convenient for the staff to drive the device to move as a whole, and it is convenient to carry.

[0037] Working principle: When in use, the staff can directly start the drive motor 191. The drive motor 191 cooperates with the first belt 19 to make the two second shafts 17 rotate synchronously. At this time, the second shaft 17 will drive the screw rod 15 to rotate through two meshing first bevel gears 18. When the screw rod 15 rotates, it will drive the moving block 14 with the threaded insertion to move downward. At this time, the moving block 14 will drive the bottom plate 11 and the inflator body 12 to move downward as a whole, so that the bottom plate 11 will drive the inflator body 12 to move into the protection box 1 to protect the inflator body 12. At the same time, when the second shaft 17 rotates, the transmission shaft 25 can be driven to rotate through the second belt 28. The second bevel gears set at both ends of the transmission shaft 25 The wheel 26 will drive the third bevel gear 27 to rotate. Since the two second bevel gears 26 are arranged in back to back mode, the two third bevel gears 27 will drive the two connecting shafts 24 to rotate in back to back or in the same direction at the same time. The connecting shaft 24 will drive the rotating rod 22 to drive the protective cover 2 to rotate until it abuts against the upper surface of the protective box 1, thereby completing the closure of the protective box 1 and providing sufficient protection for the inflator body 12. At the same time, when the inflator body 12 is needed to be used later, the reverse drive motor 191 can enable the bottom plate 11 to push the inflator body 12 upward, and at the same time, the two protective covers 2 will unfold, allowing the inflator body 12 to work normally. At the same time, the air bags required to be inflated can be placed on the protective cover 2 to perform the function of placing items.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
