Description

A height-adjustable stable chair

technical field

The invention relates to a chair, in particular to a height-adjustable stable chair.

Background technique

At present, students are almost inseparable from desks and chairs for homework, computer use, and reading every day. Improper height and posture can lead to myopia, hunchback and even scoliosis in children. However, desks and chairs with fixed specifications, no matter whether they are tall or short, cannot adjust the height of the chair according to their actual situation. With this kind of chair, some students can only relieve leg numbness by constantly changing their body positions. Constant shaking can easily cause fatigue and distraction, which will harm the body and lead to a decrease in learning efficiency. In addition, for uneven ground, chairs with fixed specifications cannot guarantee their stability. Therefore, it is especially important to develop a kind of height-adjustable stable chair.

Contents of the invention

The technical problem to be solved by the present invention is how to overcome the above-mentioned defects in the prior art and provide a height-adjustable stable chair. In order to solve the above problems, a height-adjustable device is provided below the height-adjustable stable chair. With such a design, people can adjust the height of the chair according to their actual situation.

The object of the present invention is to provide a height-adjustable stable chair, which includes: a back board, a seat board, and a height-adjustable stable device;

The height-adjustable stabilizing device includes a support vertical bar, a spring, a movable link, a column, an elastic washer, and a nut arranged below the seat board, and the two ends of the compressible spring are respectively connected with the top of the support vertical bar and the column. Two slots are opened on the support vertical bar, and a hole is opened in each column, and the movable connecting rod passes through the column hole and is stuck in the support vertical bar groove, and is tightened with a nut.

The invention discloses a height-adjustable stable chair, which has the advantages of simple structure, scientific design, convenient processing, convenient operation, etc., and can adjust the height of the chair according to the actual situation.

Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

The height-adjustable stable chair includes: column 1, nut 2, elastic washer 3, movable connecting rod 4, support vertical rod 5, spring 6, seat board 7, back support rod 8, back board 9, opening slot 10. The height-adjustable stable chair includes: a seat board 7, a back board 9, a height-adjustable stable device, and a height-adjustable stable device includes a support vertical rod 5, a spring 6, and a movable connecting rod 4 arranged under the seat board. , column 1, elastic washer 3, nut 2, the two ends of compressible spring 6 are connected with support vertical bar 5 tops and column 1 respectively, each support vertical bar 5 is opened two slots, and each column 1 is opened a hole, movable Connecting rod 4 passes column 1 hole and is stuck in support vertical bar 5 grooves, it is tightened with nut 2, so designed, is convenient to movable column 1 and adjusts its vertical height flexibly.

During use, according to one's actual situation, the position of the movable connecting rod 4 in the support vertical bar 5 grooves can be found by adjusting the nut 2 to find the height suitable for oneself. When the ground is uneven, the position of a certain column 1 in the chair can be adjusted by the compression spring 6 when the people sits on the stable chair, so as to ensure that the chair remains stable. With such a design, people can adjust the height of the chair according to their own actual conditions, effectively solving the defect that the fixed height of the desks and chairs cannot be adjusted.

The above are only preferred implementation examples of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
