Embodiment Construction
[0039] see Figure 1-4 A chair foot capable of reducing dragging noise comprises a chair body 1-1, a chair leg 1-2, a moving structure 2, a supporting structure 3, a positioning structure 4 and a limiting structure.
[0040] The chair legs 1-2 are arranged at the bottom of the chair body 1-1, the number of the chair legs 1-2 is four, and the four chair legs 1-2 are distributed at the four corners of the bottom of the chair body 1-1.
[0041] The support structure 3 is arranged outside the bottom of the chair 1; the chair legs 1-2 can move axially relative to the support structure 3.
[0042] The support structure 3 includes a support part 3-1 and a compression spring 3-2; the compression spring 3-2 is fixed at the inner bottom of the support part 3-1; the chair leg 1-2 slides in the support part 3-1; the chair leg 1 -2 When the bearing gravity is greater than fifteen kilograms, the supporting part 3-1 is in contact with the ground.
[0043] The limit structure is arranged be...

The invention discloses a chair leg capable of reducing dragging noise, and belongs to the field of chairs. The chair leg capable of reducing dragging noise comprises a chair body, chair legs, a moving structure, a supporting structure, a positioning structure and a limiting structure, the chair legs are arranged at the bottom of the chair body; the supporting structure is arranged outside the bottom; the chair legs can axially move relative to the supporting structure; the limiting structure is arranged between the supporting structure and the chair legs; the limiting structure is used for limiting the axial movement distance of the chair legs relative to the supporting structure; the number of the moving structures is two, and the two moving structures are symmetrically arranged on the chair legs; the moving structure can rotate relative to the chair legs; the positioning structure is arranged between the moving structure and the supporting structure; the positioning structure is used for supporting the rotation of the moving structure relative to the chair legs, so that the noise generated when the chair is dragged can be reduced, the floor is not easy to damage, and the normal use of the chair is not easy to influence.
Description
technical field [0001] The invention relates to the field of chairs, in particular to a chair foot capable of reducing dragging noise. Background technique [0002] Chairs are common items used in people's daily life. [0003] The sound insulation of the existing buildings is poor, and noise will be generated when the chair is moved, and the noise will cause damage to the floor surface at the same time, affecting the appearance of the floor. Children especially like to push chairs or stools to play in the room, which increases the frequency of noise. Contents of the invention [0004] 1. technical problem to be solved [0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a chair foot that can reduce the dragging noise, which can reduce the noise generated when the chair is dragging, is not easy to cause damage to the floor, and is not easy to affect the normal use of the chair . [0006] 2. Technical solutions ...
