DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-4As shown, a mobile shelf of the utility model includes

[0024] There are two assembly columns 1, which are arranged in a front-to-back distribution.

[0025] There are several supporting mechanisms 2, which are arranged vertically and mounted on the sides of the two assembly columns 1 close to each other;

[0026] The supporting mechanism 2 includes two supporting plates 21, which are distributed on the left and right sides. The two supporting plates 21 are fixedly installed with rotating shafts 22 on the front and rear sides. The two rotating shafts 22 are respectively rotatably connected to the corresponding assembly columns 1. A mounting groove 23 is opened inside the front assembly column 1, and the front ends of the two front rotating shafts 22 extend into the mounting groove 23; the specific driving component includes a connecting rod 31, and the front ends of the two front rotating shafts 22 are fixedly installed with worm gears 32. The lower end of the connecting rod 31 is rotatably connected to the bottom side of the mounting groove 23. The rotating shaft 22 is located between the two worm gears 32. A worm 33 meshing with the two worm gears 32 is fixedly installed on the periphery of the rotating shaft 22. The upper end of the connecting rod 31 extends out of the assembly column 1 and is fixedly installed with a turntable 34. A holding rod 35 is eccentrically provided on the upper side of the turntable 34.

[0027] In the initial state of use, when the mobile shelf is not needed, the two supporting plates 21 that are aligned with each other will be folded together and stored between the two assembly columns 1. In this folded state, the space required is small, which is more convenient for storage or transportation. In addition, due to the self-locking property between the worm gear 32 and the worm 33, the two supporting plates 21 in the folded state cannot be opened. When the mobile shelf needs to be used, the staff can rotate the holding rod 35, which drives the connecting rod 31 to rotate, and the connecting rod 31 drives the multiple worm gears 33 to rotate. Therefore, the worm gear 33 is located between the two worm gears 32, so the worm gear 33 can drive the two worm gears 32 to rotate in opposite directions.

[0028] The driving assembly 3 is arranged inside the mounting groove 23 and is used to drive the two rotating shafts 22 to rotate in opposite directions; the specific driving assembly includes a connecting rod 31, and the front ends of the two front rotating shafts 22 are fixedly installed with worm gears 32. The lower end of the connecting rod 31 is rotatably connected to the bottom side of the mounting groove 23. The rotating shaft 22 is located between the two worm gears 32. A worm 33 meshing with the two worm gears 32 is fixedly installed on the periphery of the rotating shaft 22. The upper end of the connecting rod 31 extends out of the assembly column 1 and is fixedly installed with a turntable 34. A holding rod 35 is eccentrically provided on the upper side of the turntable 34.

[0029] In the initial state of use, when the mobile shelf is not needed, the two supporting plates 21 that are aligned with each other will be folded together and stored between the two assembly columns 1. In this folded state, the space required is small, which is more convenient for storage or transportation. In addition, due to the self-locking property between the worm wheel 32 and the worm 33, the two supporting plates 21 in the folded state cannot be opened. When the mobile shelf is needed, the staff can rotate the holding rod 35, the holding rod 35 drives the connecting rod 31 to rotate, and the connecting rod 31 drives the multiple worms 33 to rotate, so that the worm 33 is locked. 3 is located between the two worm gears 32, so the worm 33 can drive the two worm gears 32 to rotate in opposite directions, so that the two carrying plates 21 will slowly open until they are in a horizontal state. This operation method can simultaneously adjust multiple carrying plates 21 from a closed state to a horizontal state. The carrying plates 21 in a horizontal state can be used to place goods, and due to the self-locking between the worm gear 32 and the worm 33, the state of the carrying plates 21 is fixed, which is simple and convenient to operate. When not in use later, the holding rod 35 can be rotated to drive several carrying plates 21 to close again.

[0030] Except for the two bottom load plates 21, the rest of the load plates 21 are fixedly installed with U-shaped limit plates 4 on their upper sides; after the several load plates 21 are changed from the closed state to the horizontal state, the staff can place the goods on the upper sides of the several load plates 21 in sequence, and the U-shaped limit plates 4 can limit the goods to prevent them from slipping.

[0031] Two lockable universal wheels 211 are installed on the lower side of the two lowest supporting plates 21. The two lockable universal wheels 211 on the left and the two lockable universal wheels 211 on the right are arranged alternately. The lower side of the left supporting plate 21 is provided with two first openings 212 that match the positions of the two lockable universal wheels 211 on the right, and the lower side of the right supporting plate 21 is provided with two second openings 213 that match the positions of the two lockable universal wheels 211 on the left.

[0032] In the initial state, when the two lowermost supporting plates 21 are closed together, the two left-side locking universal wheels 211 are stored in the two second openings 213, and the two right-side locking universal wheels 211 are stored in the first opening 212. The two supporting plates 21 are close together. After the two supporting plates 21 are in a horizontal state, the four locking universal wheels 211 will extend out of the two first openings 212 and the two second openings 213. After the staff adjusts the mobile shelf to be upright, the four locking universal wheels 211 are released from the ground to provide support for the mobile shelf, and it is also convenient to move the position of the mobile shelf.

[0033] The device is used as follows:

[0034] In the initial state, several groups of carrying plates 21 are in a closed state with each other. Therefore, when the mobile shelves are not needed, it is more convenient to store, place and transport. When it is needed, just rotate the holding rod 35, and the holding rod 35 drives the turntable 34 to rotate, and the turntable 34 drives the connecting rod 31 to rotate. The several worms 33 installed around the connecting rod 31 will synchronously drive the several worm gears 32 to rotate. Taking one group of worm gears 32 as an example, the forward and reverse rotation of the worm 33 can drive the two worm gears 32 to rotate forward and reverse, and the rotation directions of the two worm gears 32 are opposite. In this way, several carrying plates 21 can be synchronously driven to open from a closed state and gradually change to a horizontal state. After the change is completed, the goods can be placed, and the several carrying plates 21 can be restored to their original state when not in use.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
