[0027] According to the structural characteristics and functional requirements of the cargo box storage space, in order to achieve high maintainability, high reliability and unpowered storage, roller transmission, mechanical limit, spring return and other technologies are adopted to realize the functions of cargo box locking limit, horizontal movement and automatic interface.

[0028] The non-powered roller type multi-storage precise positioning shelf of the present invention can be divided into multiple layers according to the space usage, and multiple boxes can be positioned and stored on each layer, and it has the function of flexibly designing the shelf structure size according to the space usage. Taking the shelf storing 4 boxes as an example, the boxes are divided into 2 layers for positioning and storage, and 2 boxes are stored on each layer.

[0029] The non-powered roller type multi-storage precise positioning rack is composed of a rack 1, a transmission device 2, a locking mechanism 3, etc., which can realize multi-storage positioning storage of cargo boxes, and the simultaneous horizontal transmission and transportation of single-layer cargo boxes and positioning kinetic energy. As shown in Figure 1, this non-powered roller type multi-storage precise positioning rack has 4 cargo box storage positions. The number of storage cargo box layers can be increased by adjusting the height of the rack 1, and the number of single-layer storage cargo boxes can be increased by adjusting the length of the rack 1. The transmission device 2 is arranged on the rack 1 in two layers, the upper and lower layers, and the locking mechanism 3 is arranged symmetrically on the single-layer rack 1. The cargo box 4 realizes the locking function of the cargo box on the rack 1 through the locking mechanism 3.

[0030] When the cargo box 4 enters the shelf 1, the external power source of the transmission device 2 first docks with the interface of the transmission device 2, and then the external device docks with the locking mechanism 3 to complete the unlocking action of the locking mechanism 3. The power is input through the external power source of the transmission device 2, and the transmission rollers in the single-layer transmission device 2 move at the same time, transporting the cargo box 4 horizontally to the specified position of the shelf 1 and stopping the movement, releasing the docking of the external device with the locking mechanism 3, completing the positioning and locking state of the cargo box 4 on the shelf 1, and finally releasing the docking of the external power source with the interface of the transmission device 2, completing the overall process of the cargo box entering the warehouse. When the cargo box 4 is transported out of the shelf, the external power source of the transmission device 2 docks with the interface of the transmission device 2, and then the external device docks with the locking mechanism 3 to complete the unlocking action of the locking mechanism, and the power is input through the external power source of the transmission device 2, and the transmission rollers in the single-layer transmission device 2 move at the same time, transporting the cargo box 4 horizontally and stopping the movement, releasing the docking of the external device with the locking mechanism 3, completing the positioning and locking state of the cargo box 4 on the shelf 1, and finally releasing the docking of the external power source with the interface of the transmission device 2, completing the overall process of the cargo box 4 leaving the warehouse.

The slider fixing plate 308 is fixed to the side support column of the shelf 1 by bolts, providing a support foundation for the fixed guide slider 307; the fixed guide slider 307 is fixed to the slider fixing plate 308 by bolts, and is arranged in two directions horizontally and vertically, providing sliding tracks and limits for the unlocking crossbar 303 and the locking vertical bar 305; the unlocking interface 301 is connected and fixed to one end of the unlocking crossbar 303, located on the outside of the shelf 1, which is convenient for docking with an external unlocking device; the locking limit block 306 is fixed on the locking vertical bar 305, and the locking and unlocking functions of the cargo box 4 on the shelf 1 are realized by adjusting the position of the locking limit block 306; the horizontal push block 302 is fixed on the unlocking crossbar 303, and the vertical push block 304 is fixed at the lower end of the locking vertical bar 305, and the position adjustment of the locking limit block 306 is completed by the coordinated movement of the horizontal push block 302 and the inclined surface on the vertical push block 304.

[0034] refer to Figure 5 , the cargo box is in a locked state, the cargo box 4 is in a locked state on the shelf 1, and the default is the initial state. The locking limit block 306 is combined with the locking interface of the cargo box 1 to achieve the limit of the cargo box 4 on the shelf 1.

[0035] refer to Figure 6 , the cargo box is in unlocked state. When the external device provides unlocking thrust, the external device interface docks with the unlocking interface 301 and provides lateral thrust, so that the unlocking interface 301, the lateral push block 302, and the unlocking cross bar 303 move horizontally to the left on the fixed guide slider 307. Through the coordinated movement of the lateral push block 302 and the upper inclined surface of the vertical push block 304, the vertical push block 304, the locking vertical bar 305, and the locking limit block 306 move upward in the vertical direction on the fixed guide slider 307. The locking limit block 306 is separated from the locking interface of the cargo box 4, and the unlocking state of the cargo box 4 on the shelf 1 is completed. When the external device withdraws the unlocking thrust, the locking limit block 306 returns to the initial state, and the locked state of the cargo box 4 on the shelf 1 is realized again.
