[0044] Working principle:

[0045] Under normal circumstances, the equipment is in a retracted state, which effectively reduces the floor space occupied and facilitates transportation;

[0046] When the equipment is in the retracted state and the door panel 4 needs to be opened, the motor I10 works, driving the two lead screw slider groups I6 to work simultaneously. The two lead screw slider groups I6 drive the lower ends of the two support rods 7 to move upward, and the upper ends of the two support rods 7 push the lower end of the window panel 8 to open, making it convenient for manual opening of the door panel 4 to enter the equipment and improve the utilization rate of the equipment.

[0047] When it is necessary to expand the equipment, firstly, the electric cylinder 11 works, and the electric cylinder 11 pushes the upper frame 5 to move upward, pushing the upper frame 5 to the upper end face of the bottom frame 1. Then, the bidirectional lead screw group 3 works, driving the two side frames 2 to move outward at the same time. The two side frames 2 expand the bottom frame 1, increase the internal space of the equipment, increase the indoor net height, and increase the personnel capacity.

[0048] When it is necessary to place or retrieve items inside the storage cabinet 12, the person places or retrieves items inside the storage cabinet 12 by opening the cabinet door on the side of the storage cabinet 12.

[0049] When the storage bed 13 is in the tightened state, when an employee places items into the internal cavity of the bed frame 1301, the motor II 1305 starts, driving the bed side cover 1304 to open the side opening of the bed frame 1301, allowing the employee to place items into the internal cavity of the bed frame 1301. When a person needs to rest, the lead screw slider assembly II 1303 operates, driving the inner bed frame 1302 to be pulled out from the side of the bed frame 1301 into a bed shape. At this time, the upper surface of the bed frame 1301 and the upper surface of the inner bed frame 1302 combine to form a bed for people to rest, improving the utilization rate of the equipment.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
