The end of the top rod 252 in the semicircular notch 4 is an arc surface. The positioning plate 352 rotates in the semicircular notch 4 to switch the cabinet door 21 between closing and opening.

[0029] The placement assembly 36 includes a rotating roller 361, a conveyor belt 362, a positioning ring 363, a pressure plate 364, a plug rod 365, a slot 366, a compression spring 367, a clamping block 368 and a stop rod 369. Two rotating rollers 361 are symmetrically installed on the front and rear sides of the placement plate 33. The two rotating rollers 361 are connected by a conveyor belt 362. A plurality of positioning rings 363 are equidistantly arranged on the outside of the conveyor belt 362 to limit the bottom of the fire extinguisher. The positioning ring 363 is an annular structure formed by splicing a plurality of arc-shaped plates. A plurality of slots 366 are provided on the upper surface, and a rod 365 is inserted into the slot 366, and the rod 365 is movably connected to the bottom wall of the slot 366 through a compression spring 367.

The placement block 6 is at the same height as the roller 32 and is in contact with the inner wall of the cabinet 1 to support the placement plate 33. The design of the placement block 6 helps to pull out the placement plate 33, reducing the process of the roller 32 and the slide 31 being detached.

[0032] A pad 1 7 is provided on the front side of the upper surface of the pressure plate 364, and a pad 2 8 is provided on the rear side of the top wall inside the cabinet 1. The pads 1 7 and 2 8 have the same height, and the opposite sides of the pads 1 7 and 2 8 are both sloped. The pads 1 7 and 2 8 are both used to press the pressure plate 364 downward. The pressed pressure plate 364 will press the top of the fire extinguisher through the clamping block 368 to reduce its shaking during transportation. When the pad 1 7 contacts the cabinet 1, the pad 2 8 contacts the rear end of the pressure plate 364. When the placement plate 33 is pushed into the cabinet 1, the pressure plate 364 can be pressed down synchronously to complete the fixation of the fire extinguisher. The design of the pad 2 8 ensures that after the placement plate 33 is pulled out, the compression spring 367 has enough rebound space, so that the clamping block 368 is separated from the top of the fire extinguisher, which is convenient for users to use.

[0033] The slide 31 extends from the rear side of the bottom wall of the cabinet 1 to the middle part. The placement plate 33 will tilt downward when being pulled out of the cabinet 1. After the placement plate 33 tilts downward, the fire extinguisher on the front side is taken first. Under the influence of gravity, the conveyor belt 362 will move to transport the fire extinguisher on the rear side to the front side and be blocked by the blocking rod 369 waiting for taking, thereby realizing the rapid supply of fire extinguishers. Multiple fire extinguishers can be taken at one location, which is easy to operate.

[0034] A guide hole 9 is provided on the vertical plate 34, and a sliding block 10 is slidably connected in the guide hole 9. The sliding block 10 has an I-shaped cross-section and slides in the guide hole 9. Its two sides contact the side surfaces of the vertical plate 34 to form a limit position to avoid shaking during movement. Both sides of the sliding block 10 are fixedly connected to magnetic blocks 11 through connecting rods for fixing them on the fire extinguisher bottle.

[0035] When the device is used, the cabinet 1 is installed in the truck bed of the mini fire truck, and the opening of the cabinet 1 is located on the side wall of the truck bed, that is, the side wall of the truck bed needs to be opened, and the cabinet 1 can be used as a seat or a shelf in the truck bed;

[0036] The positioning plate 352 is rotated so that the push rod 252 is inserted into the arc groove 1 353, and the positioning plate 352 is pulled outward to bring out part of the placement plate 33, and the cabinet door 21 is opened. In the process of the placement plate 33 being pulled out, the placement block 6 is separated from the cabinet body 1, and the front end of the placement plate 33 is tilted downward. The cabinet door 1 is supported on the lower surface of the placement plate 33, the pad 1 7 is separated from the cabinet body 1, and the pad 2 8 is separated from the pressure plate 364. The pressure plate 364 is lifted up by the compression spring 367, and the pressing block 368 is separated from the top of the fire extinguisher, and the fire extinguisher at the front side is directly used. Then, under the influence of gravity, the conveyor belt 362 will move to transport the fire extinguisher at the rear side to the front side and is blocked by the blocking rod 369 to wait for use;

[0037] Push the conveyor belt 362 to insert the fire extinguishers into the positioning ring 363 one by one until the fire extinguishers on the front and rear sides are blocked by the blocking rod 369, move each sliding block 10 to make the magnetic block 11 adsorb on the corresponding fire extinguisher, and then push the placement plate 33 into the cabinet 1. The pressure plate 364 is pressed by the pad 1 7 and the pad 2 8 so that the clamping block 368 presses the top of the fire extinguisher, and then close the cabinet door 21, rotate the positioning plate 352 so that the top rod 252 is inserted into the arc groove 2 354 to complete the fixation.
