Embodiment 1

[0058] Such as figure 1 and 2 As shown, the present embodiment provides a multi-layer winding spring, the multi-layer winding spring is formed by tightly fitting and winding several pieces of elastic metal sheets 10;

[0059] Each piece of elastic metal sheet 10 includes: a stretch connection part 11 that does not participate in winding and unwinding and always maintains the initial state (after the multi-layer winding spring is rolled up to the limit position, the stretch connection part 11 is elastic metal sheet 10 rolled The outermost layer of the winding part or the outermost part extending outwards), the flap part 12 that participates in winding and unwinding, and the dead roll part 13 that does not participate in stretching and keeps the winding state all the time (the dead roll part 13 The number of winding turns is usually not less than one turn, and in certain cases less than one turn);

[0060] The stretch connecting part 11, the flap part 12 and the unrolled part ...

Embodiment 2

[0078] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0079] Such as Figure 5 As shown, the stretch connection part 11 of the elastic metal sheet 10 is provided with a connection structure for connecting with the connected parts;

[0080] The connection structure on part or all of the elastic metal sheet 10 (inner layer metal sheet 102 in this embodiment) is a semi-limited structure 14 .

[0081] Such as Figure 6 and 7 As shown, the semi-limited structure 14 is provided with a movable margin δ in the direction of unfolding or rolling up the elastic metal sheet 10;

[0082] During the unfolding or winding process of the multi-layer winding spring, the stretched connecting part 11 of the elastic metal sheet 10 provided with the semi-limited structure 14 is slidably arranged relative to the connected parts within the range of the movable margin δ.

[0083] In use, after the tension connection parts 11 of the multi-l...

Embodiment 3

[0101] This embodiment discloses a lifting bracket with the above-mentioned multi-layer winding spring, which includes a column and a lifting seat;

[0102] The lifting seat can be slid up and down on the column;

[0103] The tensile connection part 11 of the multi-layer winding spring is connected to the lifting seat or the column;

[0104] The stretched connecting part 11 of the elastic metal sheet 10 provided with a semi-limited structure can be slidably set relative to the lifting seat or the column within the range of activity margin;

[0105] The dead roll part 13 of the multi-layer coil spring is rotatably arranged on the column or the lifting seat;

[0106] The multi-layered coil springs tend to force the lift stand upwards, thereby providing support to support the lift stand.

[0107] The dead roll part 13 of the multi-layer coil spring is rotatably arranged on the column or the lifting seat through the rotating drum or the half-covered constant force spring seat. ...

Abstract

The invention provides a multi-layer coiled spring and a lifting support thereof and relates to the technical field of coiled springs. The multi-layer coiled spring is formed by closely coiling a plurality of elastic metal sheets in an attached mode. Each elastic metal sheet comprises a stretching connecting part not participating in coiling and spreading and keeping in an initial state all the time, a sheet moving part participating in coiling and spreading and a dull coiling part not participating in stretching and keeping in a coiling state all the time, wherein the stretching connecting part, the sheet moving part and the dull coiling part are sequentially arranged in the spreading direction; and the parts, positioned on the dull coiling part, of the plurality of elastic metal sheets are arranged in a relatively fixed manner. According to the multi-layer coiled spring, the coiled ends of the elastic metal sheets are relatively fixed, so that dislocation of the elastic metal sheets of a coiling block part of the coiled spring is effectively avoided; the phenomenon of arching of the coiled spring is effectively avoided; the service life of the multi-layer coiled spring is greatly prolonged; and application and popularization of the multi-layer coiled spring are made possible.

Description

technical field [0001] The invention relates to the technical field of coil springs, in particular to a multi-layer coil spring and a lifting bracket thereof. Background technique [0002] At present, the display screen is usually supported by a lifting bracket. The lifting bracket includes a column and a lifting seat, and the display screen is arranged on the column in a height-adjustable manner through the lifting seat. [0003] A constant force spring (a kind of winding spring) is arranged between the column and the lifting seat, and the display screen can be stopped when the height is adjusted by the constant force spring. [0004] In order to meet the ultra-thin development requirements of the column, those skilled in the art try to replace the existing single-layer constant force spring with multi-layer coiled springs, thereby effectively reducing the space occupied by the constant force spring in the column, and then realizing the compactness of the column. Ultra-thi...
