[0002] Shelves are important tools for modern warehouses to improve efficiency. With the rapid economic development, a large number of foreign-funded enterprises have flooded into the Yangtze River Delta and Pearl River Delta regions of our country, which not only drives the local economic development, but also brings new management concepts and management technologies. During the logistics transportation process, it is often necessary to place the transported goods on some storage shelves. In order to reduce the occupied space of the goods and improve the space utilization rate of the storage room, the storage shelves are generally set in a multi-layer shape, and multiple layers of goods can be stored at the same time.

[0003] After retrieval, a patent document with the publication number of CN216416445U discloses a height-adjustable metal mezzanine storage shelf, which includes a concave-shaped shelf and a lifting device. A fixed shelf board is installed at the upper end inside the concave-shaped shelf, and a movable shelf board is arranged at the lower end of the fixed shelf board; the lifting device includes a driving motor, two lead screws and a driven shaft. The driving motor is installed at the lower end of the front side of the concave-shaped shelf, and the output end of the driving motor is connected to a driving shaft. The two lead screws are rotatably connected to the inner upper and lower end inner walls of the concave-shaped shelf. The lower ends of the two lead screws are installed with driven gears. Driving gears are installed at the ends of the driving shaft and the driven shaft, and a transmission belt is sleeved between the driving shaft and the driven shaft.
