DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] like Figure 1-Figure 7 As shown, the utility model is a folding shelf, including a frame top 1, columns 2 and a frame body 3, the columns 2 are arranged on the frame top 1, and the columns 2 are provided with four groups, and the four groups of columns 2 are respectively arranged at the four corners of the frame top 1, the frame body 3 is arranged on the columns 2, the frame body 3 includes a main frame 7 and a folding frame 8, the main frame 7 includes a main support frame 9 and a main layer plate 10, the main support frame 9 is arranged on the columns 2, the main layer plate 10 is arranged on the main support frame 9, the folding frame 8 includes a folding support frame 11 and a folding layer plate 12, a support 4 is provided on the column 2, the folding support frame 11 is hingedly arranged on the support 4, and the folding layer plate 12 is arranged on the folding support frame 11; a self-locking universal wheel 20 is provided at the bottom of the column 2; the folding frame 8 is symmetrically provided with two groups; the frame body 3 is provided with a plurality of groups from top to bottom, and in the plurality of groups of frame bodies 3, the connecting rods 13 located on the same side are parallel to each other.

[0022] The column 2 is provided with a driving assembly for driving the folding support frame 11 to rotate, and the driving assembly includes a connecting rod 13 and a sleeve block 14. The column 2 is provided with a slide groove 6, and a screw rod 5 is rotatably arranged in the slide groove 6. The sleeve block 14 is sleeved on the screw rod 5 through a thread and slidably arranged in the slide groove 6. The connecting rod 13 is hinged on the sleeve block 14 and hinged on the folding support frame 11; one end of the screw rod 5 is rotated to extend outside the slide groove 6 and rotates through

[0023] A driven sprocket 17 is sleeved on the screw rod 5 on the frame top 1, a bracket 15 is provided on the frame top 1, a motor 16 is provided on the bracket 15, a driving sprocket 18 is sleeved on the output shaft of the motor 16, and a chain 19 is sleeved on the driven sprocket 17 and the driving sprocket 18.

[0024] In specific use, when the shelf needs to be used to display or store objects, the motor 16 is started, and the motor 16 drives the active sprocket 18 to rotate, and the active sprocket 18 drives four sets of driven sprockets 17 to rotate synchronously through the chain 19, and the four sets of driven sprockets 17 respectively drive four sets of screw rods 5 to rotate synchronously, and the screw rod 5 drives the sleeve block 14 to move downward, and the sleeve block 14 drives the folding support frame 11 to rotate through the connecting rod 13, so that the folding support frame 11 is unfolded. At this time, more items can be stored through the main layer 10 and the folding layer 12, making the storage function of the shelf stronger. When the shelf needs to be transported, the driving motor 16 rotates in the opposite direction, thereby driving the screw rod 5 to rotate in the opposite direction, and the screw rod 5 drives the sleeve block 14 to move upward, and the sleeve block 14 drives the folding support frame 11 to rotate through the connecting rod 13, so that the folding support frame 11 is folded up, and the volume of the shelf becomes smaller, which is more convenient to move and transport. By setting the self-locking universal wheel 20, it is more labor-saving when moving the shelf.

[0025] In summary, the shelf can adjust its usage status according to actual needs. When objects need to be displayed or stored, the folding frame 8 can be unfolded. At this time, the storage function of the shelf is stronger. When the shelf needs to be moved or transported, the folding frame 8 can be folded. At this time, the volume of the shelf can be reduced, and it is more convenient to transport and move.
