Embodiment 1

[0014] Such as figure 1 In the height-adjustable seat shown, the seat surface 1 is supported and positioned by the support rod 11, and the positioning sleeve 21 connected to the upper end of the support leg 2 is inserted into the support rod 11, wherein a support rod 11 is arranged between the support rod 11 and the bottom surface of the sleeve 21. A compression spring 3 is arranged. In this embodiment, several support legs support the chair surface through a support rod.

Embodiment 2

[0016] Such as figure 2 In the height-adjustable seat shown, the seat surface 4 is supported and positioned by a plurality of support rods 41, wherein each support rod 41 corresponds to a support foot 5, and a sleeve-type inner cavity 51 is provided on the support foot 5 for support For the insertion and positioning of the rod 41 , a compression spring 6 is arranged between the support rod 41 and the bottom surface of the inner cavity 51 .

[0017] The invention provides a chair that can automatically adjust the height according to the height. A spring is installed on each chair leg. The weight is light, and the corresponding chair is just higher. Furthermore, the height of the seat surface behind the seated person can be adjusted appropriately. This design abandons the inconvenience of height adjustment through positioning pins, but uses the general principle that taller people weigh more, while shorter people weigh less, to automatically adjust the height of the seat ...

The invention relates to a height adjustable chair. The chair comprises a seat and supporting legs and is characterized in that a compression spring is arranged between the seat and the supporting legs. The chair has the following beneficial effect: the aim of properly adjusting the seat height is achieved by arranging the compression spring between the seat and the supporting legs and adopting the fact that the amounts of compression of the spring caused by people with heavy weight and people with light weight are different.

Description

technical field [0001] The invention relates to a chair, in particular to a height-adjustable chair. Background technique [0002] In class, generally speaking, shorter students need taller chairs, and taller students need shorter chairs. In this way, it can be ensured that everyone is at a relatively consistent viewing angle, so as not to affect others or be affected by others. However, the existing height-adjustable seats are usually through an adjustment rod / column, and multiple adjustments are made on the rod body / column. An adjustment pin hole can be used to complete the positioning and fixing of the seat height, or a locking handle can be used for fixing. That is to say, its basic structure is to lock and fix the position after being adjusted to the corresponding height. Although this method can basically meet the needs, it is very troublesome to adjust, especially for places where the seats are not fixed, such as public classrooms, it will obviously not be very suit...
