One side is fixedly connected with the inner wall of the top end and the inner wall of the bottom end of the limiting frame 4 respectively, and return spring columns 13 distributed at equal intervals are fixedly connected.

Referring to Fig. 2-Fig. 4, Fig. 6 and Fig. 7, a mounting plate 10 is fixedly connected between the inner walls on both sides of the limit frame 4, and the mounting plate 10 is provided with a driving assembly for driving the cleaning plate 12 to move in the vertical direction, The drive assembly includes a mounting rod 21 that is mounted on the mounting plate 10 in a through-type rotation, and the mounting rod 21 is fixedly installed with two drive plates 16 that are symmetrically distributed and intermittently contact the cleaning plate 12. The drive plate 16 is provided with There are smooth chamfers, the rod body of the installation rod 21 is fixedly installed with fan blades 15 distributed in a circular array, and the end of the installation rod 21 away from the cabinet body 1 is fixedly installed with the driven bevel gear 14, and the inside of the installation plate 10 is equipped with a mounting plate. groove 25, and the inside of the installation groove 25 is equipped with a driving bevel gear 17 meshing with the driven bevel gear 14, and one side of the driving bevel gear 17 is fixedly installed with a rotating rod 24 rotating inside the mounting plate 10. And the transmission assembly is arranged between one end of the rotating rod 24 away from the drive bevel gear 17 and one of the sprocket wheels 6. The transmission assembly includes a main pulley 22 installed on the outer wall of the cabinet body 1 and rotates synchronously with the sprocket wheel 6, and is mounted on the limiter for rotation. The outer wall of the frame 4 and the secondary pulley 23 fixedly connected to the end of the rotating rod 24, and a transmission belt is connected between the secondary pulley 23 and the primary pulley 22.

While driving the positioning chainring 3 and the sprocket wheel 6 to rotate through the handle 26, the sprocket wheel 6 synchronously drives the main pulley 22 to rotate, the main pulley 22 synchronously drives the auxiliary pulley 23 to rotate through the transmission belt, and the auxiliary pulley 23 drives the rotating rod 24 to rotate again.

The vent hole 11 enters the inside of the cabinet body 1 and causes a serious phenomenon of ash falling in the internal files of the cabinet body 1 .

Working principle: This kind of file storage device for management science and engineering, if the height of the storage plate 7 for storing files is high during use, and it is inconvenient to take and place, first pull the movable plate 27 upwards, so that the movable plate 27 drives the positioning tooth plate 29 Move upwards, so that the tooth block on the positioning tooth plate 29 can be disengaged from the tooth block on the positioning tooth plate 3, and then the positioning tooth plate 3 is driven by the handle 26 to rotate, so that the sprocket wheel 6 can be driven to rotate, through the chain 19, the sprocket wheel 6 and the transmission of the transmission rod 5, thus the side plate 20 on the chain link of the chain 19 can drive the position of the placement plate 7 to change in the height direction, and the rotational connection between the placement plate 7 and the side plate 20 can make the placement plate 7. There is only a position translation change, and the situation that the placement plate 7 is turned over with the side plate 20 will not occur, so as to avoid the situation that the files stored in the placement plate 7 fall and cause the files to be confused. After the position that is convenient to take, stop rotating positioning chainring 3, unclamp movable plate 27, make the tooth block on the positioning tooth plate 29 and the tooth block on the positioning toothing plate 3 dislocation engagement, thus make positioning toothing plate 3 keep fixed It can not only ensure the stability of the internal file placement of the cabinet body 1, but also avoid the phenomenon of automatic rotation of the placement board 7 caused by the different loading weights of the files and books on each placement board 7.

And when the positioning chainring 3 and the sprocket wheel 6 are driven by the handle 26 to rotate, the sprocket wheel 6 synchronously drives the main pulley 22 to rotate, and the main pulley 22 synchronously drives the secondary pulley 23 to rotate through the transmission belt, and the secondary pulley 23 drives the rotating rod 24 to rotate , so that the rotating rod 24 drives the driving bevel gear 17 to rotate, the driving bevel gear 17 drives the driven bevel gear 14 to rotate, and the driven bevel gear 14 drives the mounting rod 21 to rotate, so that the mounting rod 21 synchronously drives the driving plate 16 to rotate, When the driving plate 16 was in contact with the cleaning plate 12, the cleaning plate 12 slid in the vertical direction inside the limit frame 4, and extruded the return spring column 13. When the driving plate 16 broke away from the cleaning plate 12, the return spring column 13 will reversely push the cleaning plate 12 to move, thereby making the cleaning plate 12 reciprocate in the vertical direction inside the limit frame 4, and the dehumidifying and ventilating air provided on the back of the cabinet body 1 can be cleaned by the cleaning brush on the cleaning plate 12. The hole 11 is used for dust removal and cleaning operations, avoiding the blockage of the dehumidification and ventilation holes 11, and improving the ventilation efficiency of the cabinet 1, thereby effectively preventing the files inside the cabinet 1 from being damaged by moisture, and at the same time, the rotation of the installation rod 21 can synchronously drive the fan blades 15 rotates, the fan blade 15 rotates to form an air flow, and the dust raised by the cleaning plate 12 is adsorbed to the back of the cabinet 1, so as to prevent the dust from entering the interior of the cabinet 1 through the dehumidification vent 11 and cause the internal file of the cabinet 1 Severe ash fall occurs.

It can be seen that this kind of file storage device for management science and engineering can not only solve the problem of inconvenient file picking and placing caused by the high height of traditional filing cabinets, but also eliminate the danger of using external auxiliary tools. Clean the ventilation holes of the cabinet body 1 to avoid blockage of the ventilation holes and improve the ventilation efficiency of the cabinet body 1, thereby effectively preventing the files inside the cabinet body 1 from being damaged by moisture.
