Both sides of the bottom plate 2 close to the two movable grooves 101 are fixedly connected with movable blocks 201. The two movable grooves 101 are slidably connected to the two movable blocks 201 respectively.

[0027] Two lifting slots 3 are provided on the left and right sides of the rear surface of the bottom plate 2 . The centers of the tops and bottoms of the two lifting slots 3 are fixedly connected with fixed bearings 401 . The four fixed bearings 401 are rotatably connected with two threaded rods 4 .

[0028] Further, such as Figure 1-4 As shown, a rotating shaft 501 passes through both sides of the top of the base plate 2 near the two threaded rods 4, and the bottoms of the two rotating shafts 501 are fixedly connected to the tops of the two threaded rods 4 through two fixed bearings 401 at the top of the base plate 2. The tops of the two rotating shafts 501 are fixedly connected with knobs 5. The main function is that when the device needs to be repaired, the two knobs 5 can be manually rotated to drive the two rotating shafts 501 to rotate in the same direction as the two threaded rods 4, so that the two fixed blocks 6 move up and down inside the lifting slot 3.

[0029] Further, such as Figure 1-4 As shown, the outer surfaces of the two threaded rods 4 are threadedly connected with fixed blocks 6, and the two fixed blocks 6 are fixedly connected to the limiting block 601 near the center of the base plate 2. The main function is to thread the two fixed blocks 6 and the two threaded rods 4 respectively, so that when the threaded rods 4 rotate, the fixed blocks 6 are driven to move up and down.

[0030] Further, such as Figure 1-4 As shown, limiting grooves 202 are provided on both sides of the inner wall of the base plate 2 near the two threaded rods 4, and two limiting blocks 601 are respectively slidably connected with the two limiting grooves 202. The main function is to limit the movement of the two fixed blocks 6 through the sliding connection between the two limiting grooves 202 and the two limiting blocks 601, so as to prevent the movement from being offset and enhance the stability of lifting.

[0031] Further, such as Figure 1-4As shown, the two limit blocks 601 are fixedly connected to a lifting plate 7 on one side away from the two fixed blocks 6, and the bottom of the lifting plate 7 is fixedly connected to a folding door panel 701.

Finally, the elastic force of the shock-absorbing springs 10 continuously pushes the bottom plate 2 back in the opposite direction, so that after the impact force is offset, the bottom plate 2 will be pushed back to the original position, preventing the bottom plate 2 from impacting the internal equipment and lines due to external impact, enhancing the stability and practicality of the sheet metal body 1, and facilitating use by the staff. When the device needs to be repaired, the two knobs 5 can be manually rotated to drive the two rotating shafts 501 and the two threaded rods 4 to rotate in the same direction, so that the two fixed blocks 6 can move up and down inside the lifting slot 3, and the two limit slots 202 are respectively connected to the two limit blocks 601 by sliding, so as to limit the movement of the two fixed blocks 6, prevent the movement from being offset, and enhance the stability of the lifting. Finally, the lifting plate 7 is driven downward by the two limit blocks 601, and the folding door panel 701 is driven downward until the folding door panel 701 is completely retracted into the storage slot 8. At this time, the groove at the center of the bottom plate 2 is opened for the convenience of the staff to repair. After the maintenance is completed, the two knobs 5 are rotated in the opposite direction. Similarly, the lifting plate 7 drives the folding door panel 701 to completely cover the groove of the bottom plate 2, so as to prevent dust and debris from entering the sheet metal body 1, which is convenient for the staff to perform daily maintenance.
