DETAILED DESCRIPTION

[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] Embodiment 1:

[0026] like Figure 1 to Figure 6As shown, the mobile storage shelf with a cantilever structure of the present embodiment includes a frame 1, a movable cantilever 2 is arranged in the frame 1, and the movable cantilever 2 includes a rotating rod 21, a toothed belt 22, a gear 23 and a loading tray 24, the toothed belt 22 is arranged on the inner side walls of the frame 1, and the upper and lower ends of the toothed belt 22 are meshed and connected with gears 23, and the gears 23 corresponding to the positions in the toothed belts 22 in the inner side walls of the frame 1 are connected through the rotating rod 21, and the rotating rod 21 is used to ensure that the toothed belts 22 on the inner side walls of the frame 1 move synchronously, and the toothed belts 22 on the inner side walls of the frame 1 are fixedly connected to the loading tray 24, when the rotating rod 21 drives the gear 23 to rotate, the gear 23 rotates to drive the toothed belt 22 meshed therewith to move, and the movement of the toothed belt 22 drives the loading tray 24 fixedly connected thereto to move up and down, and the loading tray 24 moves while driving the items placed thereon to move.

[0027] The synchronization effect of the mobile devices at both ends of the loading tray 24 in the prior art is not very ideal. Once the mobile device at one end loses power, the items placed on the loading tray 24 will fall over and be damaged. In view of this, in the utility model, a movable cantilever 2 is provided in the frame 1, and the loading tray is composed of a rotating rod 21, a toothed belt 22, a gear 23 and a loading tray 24. The toothed belt 22 is installed on the inner walls of both sides of the frame 1, and the upper and lower ends of the toothed belt 22 are respectively meshed and connected with corresponding gears 23. The gears 23 at the corresponding positions of the inner walls of the two sides of the frame 1 are connected to each other through the rotating rod 21. The function of the rotating rod 21 is to ensure that the toothed belts 22 on the inner walls of both sides of the frame 1 can move synchronously. The toothed belt 22 is fixedly connected to the loading tray 24. When the rotating rod 21 is driven, it drives the connected gear 23 to rotate. The rotation of the gear 23 causes the toothed belt 22 meshing therewith to move along the inner wall of the frame 1. Since the toothed belt 22 is fixedly connected to the loading tray 24, the movement of the toothed belt 22 drives the loading tray 24 to move up and down. The movement of the loading tray 24 further causes the objects placed thereon to move in the vertical direction, thereby realizing the lifting and access functions of the objects. Through this structural design, the vertical movement of the loading tray 24 can be effectively controlled, and the loading, unloading and storage of objects can be conveniently performed.

[0028] like Figure 1-Figure 6 As shown, a driving mechanism 3 is provided in the frame 1, and the driving mechanism 3 includes a servo motor 31, a driving wheel 32 and a driven wheel 33. The driving wheel 32 is fixedly connected to the rotating shaft of the servo motor 31, and the driven wheel 33 is fixedly connected to the rotating wheel. The driving wheel 32 and the driven wheel 33 are in a meshing state. When working, the servo motor 31 drives the driving wheel 32 to rotate, and the rotation of the driving wheel 32 drives the driven wheel 33 meshed therewith to rotate, and the rotation of the driven wheel 33 drives the rotating rod 21 to rotate.

[0029] In the mobile storage shelf, a driving mechanism 3 is arranged in the frame 1, and the driving mechanism 3 is composed of a servo motor 31, a driving wheel 32 and a driven wheel 33. The servo motor 31 serves as a power source, and its rotating shaft is fixedly connected to the driving wheel 32 to ensure that the rotation of the driving wheel 32 can be directly driven by the servo motor 31. The driven wheel 33 is fixedly connected to the rotating rod 21. The driving wheel 32 and the driven wheel 33 are in a meshing state to achieve force transmission. During operation, the servo motor 31 starts and drives the driving wheel 32 to rotate. The rotation of the driving wheel 32 is transmitted to the driven wheel 33 through the meshing mechanism, so that the driven wheel 33 also rotates. The rotation of the driven wheel 33 directly drives the rotating rod 21 fixedly connected thereto to rotate. The rotation of the rotating rod 21 can further drive the mobile cantilever 2 to achieve the up and down movement of the loading tray 24 or the items to meet different storage and retrieval requirements. The design of the entire driving mechanism 3 ensures the effective transmission and precise control of power. Through the precise control of the servo motor 31, the moving speed and position can be precisely adjusted to improve the working efficiency and stability of the storage shelf.

[0030] like Figure 1-Figure 4 As shown, a limit block 11 is provided in the frame 1, and the limit block 11 is used to limit the movement of the loading tray 24 to prevent the loading tray 24 from turning over during the movement.

[0031] In the mobile storage shelf, the frame 1 is provided with limit blocks 11, which are used to limit the movement of the loading tray 24 to prevent the loading tray 24 from flipping over during movement. The limit blocks 11 interact with the loading tray 24 to ensure that it remains stable when rising or falling and moves along a predetermined path. In this way, even when the loading tray 24 carries heavy items or moves quickly, it can avoid flipping due to loss of balance, thereby ensuring the safety of shelf operation and the integrity of items. The setting of the limit blocks 11 improves the stability and reliability of the shelf, making it more adaptable to the needs of efficient operation in logistics and warehousing environments.

[0032] The portion of the loading tray 24 that contacts the limiting block 11 is provided with a limiting roller 25, and the limiting roller 25 is used to reduce the friction between the loading tray 24 and the limiting block 11. In the mobile storage shelf, the loading tray 24 is provided with limiting rollers 25, and these limiting rollers 25 are located at the portion where the loading tray 24 contacts the limiting block 11. The limiting rollers 25 are designed to reduce the friction between the loading tray 24 and the limiting block 11 during movement. When the loading tray 24 moves along the guide rail or moving path of the shelf, the limiting rollers 25 contact and roll with the limiting block 11, rather than simply sliding in contact.

[0033] Embodiment 2:

[0034] Compared with Example 1, Figure 1As shown, the frame 1 is provided with a plurality of chassis 4, and the chassis 4 is used to store goods. In the mobile storage rack, the frame 1 is provided with a plurality of chassis 4, and the main function of these chassis 4 is to store goods. Each chassis 4 is equivalent to an independent storage unit, and can be designed according to the size and weight of the goods to meet different types of storage requirements.

[0035] The frame 1 is provided with a universal moving wheel 5 at the bottom, and the universal moving wheel 5 is used for the movement of the shelf. The universal moving wheel 5 is usually composed of a wheel axle fixed at the bottom of the frame 1 and a plurality of wheels that can rotate freely around the wheel axle. Each wheel can roll independently in any direction, so that the mobile storage shelf can adapt to different storage environments and operation requirements.

[0036] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
