Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a lifting bracket with damping rotation. Background Art

[0002] The lifting bracket can make the table top freely rise and fall in height, but the table top angle adjustment structure is relatively complicated.

[0003] After searching, the patent with application number CN201811625168.6 discloses a lifting and flipping adjustable learning table, which includes a table top, a bracket and a bottom plate from top to bottom. The bracket includes a main bracket and a secondary bracket. The main bracket includes an upper bracket and a lower bracket. The upper bracket is rotatably connected to the crossbeam through a rotating shaft. The upper bracket is also provided with a support rod. The lower bracket is rotatably connected to the bottom plate through a rotating shaft. The lower bracket is provided with a guide hole that matches the upper bracket along the axis. The upper bracket is slidably connected to the lower bracket. The upper bracket is provided with a card slot. The upper end face of the lower bracket is rotatably connected to the card plate; a second slide is provided on the bottom plate, and a second positioning hole is provided on the second slide; one end of the secondary bracket is rotatably connected to the lower bracket through a rotating shaft, and the other end of the secondary bracket is connected to a second slider. The second slider is slidably connected to the second slide, and the second slider is slidably connected to the second positioning hole. The learning table of this scheme can adjust the height and the angle of the table top, and can also be folded for easy storage and transportation.

[0004] When adjusting the angle of the table top, this solution puts the clutch 803 in a disengaged state, pulls the first positioning rod 105 by hand to make it leave the first positioning hole 103, rotates the table top 10 with the shaft 804 as the rotation center, and the first slider 104 slides along the first slide groove. When the table top 10 rotates to the required angle, stop pulling the first positioning rod 105. Under the thrust of the first compression spring 107, the first positioning rod 105 is inserted into the corresponding first positioning hole 103 to fix the table top 10.

[0005] The above-mentioned rotatable lifting table has a complex tabletop angle adjustment structure and a cumbersome adjustment method. The user needs to squat on the side of the lifting table to adjust it manually, which is troublesome. During the adjustment process, one hand is required to support the tabletop and the other hand is required to insert the first positioning rod into the corresponding first positioning hole. The adjustment is difficult and there are safety hazards. It is easy to pinch the hand. Therefore, we need to propose a lifting bracket with damped rotation. Utility Model Content
