Description

Adjustable student uses chair

Technical field

The present invention relates to a kind of wooden chair, particularly a kind of adjustable student uses chair, belongs to the furniture technical field.

Background technology

Wood chair application is extensive, no matter in the office of institutional settings, can see in the classroom of school and the general family.Existing different students is the timber structure that a kind of traditional mortise and tenon connects with the structure of wooden chair, and the structure outward appearance is horizontal vertically flat, and is very steady; Meet Chinese aesthetic habit, but this structure has only a kind of level altitude, very unfavorable to student's growth; Modern student's speed of growth is uneven; Student's height difference of the same age is big, and the level altitude chair can be all influential to student's sitting posture, eyesight, in order to adapt to the height of student's different growing stages; School, family all can not stop to buy the chair of different size, when increasing purchase cost, also cause the wasting of resources.

Summary of the invention

The technical problem formula that the present invention will solve provides a kind of firm Height Adjustable wooden chair of stable high seat, the chair back, has prolonged the service life of wooden chair, economizes on resources.

The technical scheme that the present invention takes: a kind of adjustable student uses chair; Structure comprises seat, chair frame, the chair back and the connecting rod that is fixedly connected; Seat has the tenon that is connected with the chair frame of both sides with chair back two ends; The chair frame top of both sides has three mortises that upwards stagger backward and arrange of pegging graft with the tenon at chair back two ends, and the chair frame middle part of both sides has three mortises that upwards stagger and arrange of pegging graft with the tenon at seat two ends, has between the chair frame of both sides to connect to be fixedly coupled bar; The chair frame of both sides is two chair framves that both sides chair leg and chair back pole separately respectively is connected as a single entity, and connecting rod is that two ends have the bar of screw and pass the connecting hole of chair frame and the bolt that is connected with screw.

The beneficial effect that the present invention obtains is: adopt three-position type to regulate seat, chair back height, enlarge the scope of application of wooden chair, the chair frame is an one, whenever connects wooden chair with connecting rod fixingly, increases the durable and steadiness of wooden chair.

Description of drawings

Accompanying drawing has been represented a kind of structural representation of the present invention; Wherein, Fig. 1 is the design sketch of seat in the extreme higher position, and Fig. 2 is the design sketch of seat in the centre position, and Fig. 3 is the design sketch of seat in extreme lower position.Each label is represented as follows among the figure: (1) seat, and (2) chair frame, (3) tack hexagon socket head cap screw, (4) two ends are embedded with the bar of inside and outside tooth screw, (5) chair back.

The specific embodiment
