A vertical groove 39 for the first moving block 38 to slide is provided on the inner wall of the rear side of the fire extinguisher box body 1, and a driving structure is provided between the transmission plate 37 and the rotating shaft. The moving structure includes a guide frame 41 arranged in the middle of the inner side of the flip plate 33, a second moving block 42 is slidably arranged in the guide frame 41, and the second moving block 42 is installed on the placement tube 6. The rear side of the placement tube 6 is connected with an insertion rod 40, and an arc groove 43 for one end of the insertion rod 40 to be movably inserted is opened on the rear inner wall of the fire extinguisher box body 1; The driving structure includes a second driving strip 44 connected to the top of the transmission plate 37, a through slot 45 for the second driving strip 44 to pass through is provided on the upper side of the fire extinguisher box body 1, a gear 46 is fixedly sleeved on the part of the rotating shaft in the through slot 45, and teeth meshingly connected with the gear 46 are provided on the second driving strip 44; The clamping structure includes a card 47 rotatably mounted on the outer side of the flip plate 33 away from the flip seat 34, a third handle 35 is mounted on the card 47, an opening 48 is opened on the card 47, and a clamping frame 49 is mounted above the left and right sides of the fire extinguisher box body 1. When taking the fire extinguisher, first, the card 47 is rotated on the flip plate 33 using the third handle 35, and the opening 48 on the card 47 is rotated to the clamping frame 49, and then the third handle 35 is used to directly pull open one of the flip plates 33 from both sides of the fire extinguisher box body 1, and one of the flip plates 33 is opened. While pulling open, the other flip plate 33 is automatically driven to rotate out through the two arc-shaped bars 36 and the transmission plate 37. At the same time, during the rotation process, the flip plate 33 drives one end of the insertion rod 40 to slide in the arc-shaped groove 43, and the insertion rod 40 drives the second moving block 42 to slide in the guide frame 41 to bring out the placement tube 6 and the fire extinguisher. The upward movement of the transmission plate 37 drives the second driving bar 44 to move upward, and the gear 46 drives the rotating shaft to rotate, so that the box cover 2 can be opened synchronously, thereby better exposing the fire extinguisher and taking the fire extinguisher.

[0020] The implementation principle of a fire extinguisher box in an embodiment of the present invention is as follows: first, the mounting plate 5 is fixed to the wall by bolts, and then the second handle 29 is used to pull the second pull rod 28 to pull the two clamping plates 31 to both sides in the adjustment frame 7, and then the mounting block 26 is inserted into the adjustment frame 7, and then the second handle 29 is directly released, and under the elastic force of the second spring 30, the two clamping plates 31 are pulled to move in the opposite direction on the adjustment frame 7 to reset, and the clamping plates 31 are moved to the mounting block 26, and the mounting block 26 is limited in the adjustment frame 7, so that the installation work of the fire extinguisher box body 1 can be realized. After installation, the fire extinguisher box body 1 needs to be adjusted. When adjusting the position, it is only necessary to use the first handle 17 to pull the first pull rod 16 upward on the fixed frame 8, and the first pull rod 16 pulls the driving frame 18 to slide upward in the driving groove 21 of the driving plate 20, and the driving frame 18 squeezes the groove wall of the driving groove 21, pushing the driving plate 20 to drive the positioning rod 22 to move toward the side away from the mounting plate 5, so that one end of the positioning rod 22 is pulled out of the positioning groove 23 on the mounting plate 5, and the positioning of the fire extinguisher box body 1 on the mounting plate 5 is released, and then the adjusting seat 9 slides on the cross bar 10 and the adjusting seat 9 slides on the vertical rod 13, and the horizontal and vertical directions on the mounting plate 5 can be adjusted. In the vertical direction, the position of the fire extinguisher box body 1 is flexibly adjusted. After the adjustment, the first handle 17 is released, and under the pulling force of the first spring 19, the driving frame 18 is pulled to slide downward in the driving groove 21 to reset, so that one end of the positioning rod 22 is inserted into the positioning groove 23 at the corresponding position on the mounting plate 5, and the fire extinguisher box body 1 after the position adjustment is repositioned. When taking out the fire extinguisher stored in the fire extinguisher box body 1, the third handle 35 is used to rotate the card 47 on the flip plate 33, and the opening 48 on the card 47 is rotated to the card frame 49, and then the third handle 35 is used to directly remove the fire extinguisher from the fire extinguisher box body 1. One of the flip plates 33 is pulled open on both sides, and when one of the flip plates 33 is pulled open, the other flip plate 33 is automatically driven to rotate out through the two arc-shaped bars 36 and the transmission plate 37. At the same time, when the flip plate 33 is rotated out, one end of the insertion rod 40 is driven to slide in the arc-shaped groove 43, and the insertion rod 40 drives the second moving block 42 to slide in the guide frame 41 to bring out the placement tube 6 and the fire extinguisher, and the upward movement of the transmission plate 37 drives the second driving bar 44 to move upward, and the gear 46 drives the rotating shaft to rotate, so that the box cover 2 can be opened synchronously, thereby better exposing the fire extinguisher and taking the fire extinguisher.

[0021] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
