Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to a double-column and double-beam shelf. Background Art

[0002] Shelves generally refer to racks for storing goods. Shelves are storage equipment used to store finished items. Display shelves refer to various display devices such as cabinets, racks, cabinets, boxes, etc. in the store business hall for displaying and placing goods to be sold. According to their uses, they can be divided into supermarket shelves, storage shelves, and display shelves. Storage shelves are divided into light shelves, medium shelves, heavy shelves, etc.

[0003] The current commodity shelves are basically single-column and single-beam structures, and the overall structural strength and load-bearing capacity are relatively average. They tend to loosen after a long period of use and are inconvenient to move. They need to be lifted and moved when transferred, which is quite laborious. Utility Model Content

[0004] The utility model provides a double-column and double-beam shelf, which is durable, not easy to loosen, and convenient and labor-saving to transfer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A double-column and double-beam shelf comprises two bases, wherein both ends of the top outer walls of the two bases are fixed with uprights, and both ends of the outer walls on the opposite sides of the two uprights on the same side are fixed with crossbeams, and cargo boards distributed equidistantly are arranged on the outer walls on the opposite sides of the two uprights on both sides, and a rotating shaft is inserted into the outer wall of one side of one of the crossbeams through a bearing, and a No. 1 bevel gear is fixed to both ends of the outer wall of the rotating shaft, and hangers are fixed to both ends of the bottom outer walls of the cargo boards, and threaded rods are inserted into the outer walls of the bottoms of the two hangers through bearings, and a No. 2 bevel gear is fixed to the tops of the two threaded rods, and lifting blocks are screwed on the two threaded rods, and a mounting plate is provided on the outer wall on the opposite side of the two lifting blocks, and movable wheels are installed at the four corners of the bottom outer wall of the mounting plate.

[0007] Through the above scheme, the overall structural strength of the shelf is improved by setting up two columns and two beams, so that the shelf is durable and not easy to loosen. When the shelf needs to be transferred and adjusted, the rotating shaft can be rotated to drive the two No. 1 bevel gears to rotate, and then drive the two No. 2 bevel gears and two threaded rods to rotate, so that the two lifting blocks move downward together, and then drive the mounting plate to descend, so that the moving wheels contact the ground and prop up the shelf. At this time, the shelf can be pushed to move, and the transfer is convenient and labor-saving.

[0008] Preferably, anti-slip pads are bonded to both ends of the outer walls of the bottom of the two bases.

[0009] Through the above solution, the shelf is placed on the ground more stably.

[0010] Preferably, the two No. 1 bevel gears are meshed with the two No. 2 bevel gears respectively.

[0011] Through the above scheme, the rotation of the No. 1 bevel gear can smoothly drive the rotation of the No. 2 bevel gear.

[0012] Preferably, the hanger is an inverted "U"-shaped structure.

[0013] Through the above solution, it is convenient to fix it at the bottom of the cargo board.

[0014] Preferably, a through hole is opened on the outer wall of the bottom of the hanger, a bearing is fixed on the inner wall of the through hole, and a threaded rod is fixed on the inner wall of the bearing.

[0015] Through the above scheme, the plug-in installation of the threaded rod is completed.

[0016] Preferably, a handle is fixed to one end of the rotating shaft.

[0017] Through the above solution, it is convenient to rotate the shaft.

[0018] The beneficial effects of the utility model are:

[0019] The two upright columns and two cross beams are provided to improve the overall structural strength of the shelf, making the shelf durable and not easy to loosen. When the shelf needs to be transferred and adjusted, the rotating shaft can be rotated to drive the two No. 1 bevel gears to rotate, and then the two No. 2 bevel gears and two threaded rods can be rotated, so that the two lifting blocks move downward together, and then the mounting plate is driven down, so that the moving wheels contact the ground and the shelf is propped up. At this time, the shelf can be pushed to move, and the transfer is convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
