Description
Technical field
This utility model relates to a kind of lockable single shaft air spring transfusion chair that adopts lockable single shaft air spring control chair back of the body angle of inclination, belongs to chair and makes the field.
Background technology
CN2706175Y, title " sitting posture adjustable infusion chair ", its structure is to be connected with seat support and backrest on the chair frame, chair frame front axle is connected with the shank gripper shoe, and the backrest lower end is connected with the chair frame by rotating shaft, is provided with the air spring of controlling shank gripper shoe and backrest upset respectively in chair frame bottom.Its weak point: this arm-chair adopts air spring to control the angle of its upset fully and as the power that supports backrest after the upset, very easily damages air spring.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of flip angle that can control the chair back by lockable single shaft air spring, can behind the air spring locking, decompose the lockable single shaft air spring transfusion chair of air spring institute bearing capacity again.
Design: in order to realize above-mentioned purpose of design.1, the pipe-support type chair is carried on the back two lateral canal bottoms and is adopted brace and the hinged design of bearing pin and seat curb girder rear portion, is one of feature of the present utility model.The purpose of doing like this is: the one, make the relation of being articulated and connected that formation can turn an angle between the chair back and the seat; The 2nd, what make the chair back afterwards drops on the curb girder of seat by bearing capacity, rather than lockable single shaft air spring, the service life of guaranteeing air spring.2, it is hinged that an end of brace and bearing pin and lockable single shaft air spring is adopted in the lower end of the lateral canal in the lateral canal, and the anterior hinged design of the other end of lockable single shaft air spring and seat curb girder is two of a feature of the present utility model.The purpose of doing like this is: because lockable single shaft air spring is positioned at the lower end that the chair back is connected with the seat both sides with the link of the chair back, therefore both can control the angle of inclination of chair by air spring, again can be after the air spring locking, avoid leaning on the direct impulsive force that lockable single shaft air spring is produced behind the chair back, guaranteed the trouble free service of lockable single shaft air spring.
Technical scheme: lockable single shaft air spring transfusion chair, the pipe-support type chair back of the body is positioned at two curb girders of pipe-support type chair seat, described pipe-support type chair carries on the back that brace and bearing pin are adopted in two lateral canal bottoms and seat curb girder rear portion is hinged and rotatable, the lower end of the lateral canal in two lateral canals adopts an end of brace and bearing pin and lockable single shaft air spring hinged, and the other end of lockable single shaft air spring and seat curb girder front portion are hinged and rotatable.
This utility model is compared with background technology, and the one, can either control the angle of the upset of the chair back effectively, can avoid the damage of the chair back again to lockable single shaft air spring; The 2nd, simple in structure, reliable, practical, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of lockable single shaft air spring transfusion chair.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Lockable single shaft air spring transfusion chair, the pipe-support type chair back of the body 1 is positioned at two curb girders 4 of pipe-support type chair seat, and its processing technology is a prior art, is not described herein at this.Described pipe-support type chair 1 back of the body two lateral canals 7 bottoms adopt the lower end of the lateral canal in brace 2 and bearing pin and seat curb girder rear portion hinged 2 and rotatable, two lateral canals 7 to adopt an end of brace and bearing pin 6 and lockable single shaft air spring 3 hinged, the other end of lockable single shaft air spring 3 and seat curb girder are anterior hinged and rotatable, switch arm 5 one ends are connected with shift bar in the lockable single shaft air spring 3, the other end is positioned at a mould handrail inboard or the outside or inside casing, lockable single shaft air spring 3 is prior art, outsourcing, so this structure is not described herein.It is unlucky need to regulate chair, and with hands operating switch arm 5, switch arm 5 is opened the switch in the lockable single shaft air spring 3, with back strength the chair back is adjusted to required gradient then after, trip switch arm 5, lockable single shaft air spring 3 lockings get final product.
On need understanding: though the foregoing description is to this utility model detailed text description of contrasting; but these text descriptions; it is text description to this utility model mentality of designing; rather than to the restriction of this utility model mentality of designing; any combination, increase or modification that does not exceed this utility model mentality of designing all falls in the protection domain of the present utility model.
