Problems；People are different in many aspects, and basic sides include head, the bodily form, strength；Such as adult and child sits
During leans back on chair, the chair back need to provide different support distances and the chair back at a distance from human body back because
The difference of people is also different；Therefore, it designs and a be adapted to different people the chair and backrest of correct back-supported are provided
It is extremely urgent.
Summary of the invention
To solve the above problems, the present invention provides a kind of chair of adaptive backrest.
The technical solution adopted by the present invention to solve the technical problems is: a kind of chair of adaptive backrest, is protected with wrapping up
The bottom plate that shield and four angles are installed with fixing screws is ontology；Support plate, wind spring and rotatable rotation are provided on the bottom plate
Rotary column；The support plate front is respectively arranged with set square across column spinner up and down, and the back side is milled with slideway by being welded and fixed
Fixed plate；The triangle front edge of board is provided with limited roller and rectangular telescopic mast moving up and down；The slideway of the fixed plate
Inside it is provided with the backboard that can be moved forward and backward and be milled with rectangular strip hollow out；Among the telescopic mast and top is respectively arranged with logical
Cross the limited block being welded and fixed, slider roller and the seat surface plate for being milled with rectangular strip hollow out；It is described between two set squares
The slider roller being provided on helicla flute and telescopic mast on column spinner cooperates, and passes through tip triangular plate and be equipped with gear and fixed tooth
The positioning pin of wheel；Rack gear is provided between the gear and limited roller to be fixedly connected by welding with backboard, and gear with
Rack gear intermeshing.
Preferably, when the telescopic rod upper limit position block moves to the set square of support plate lower end, the rotation of column spinner gear
Backboard is driven to move to seat surface plate front end.
Preferably, among the telescopic mast and top be respectively arranged with by the limited block that is welded and fixed, slider roller and
It is milled with the seat surface plate of rectangular strip hollow out, and the rectangular strip hollow out being milled on seat surface plate and backboard is interspersed.
Preferably, support plate, wind spring and rotatable column spinner are provided on the bottom plate, support plate and bottom plate pass through weldering
Fixation is connect, column spinner is fixedly connected with wind spring, and wind spring gives the power rotated clockwise always.
The beneficial effects of the present invention are: the Forward by the decline rear backrest plate of seat surface plate resists human body waist, backboard
It is suitable for adult and children and accomplishes that length different on seat surface plate resists human body waist, use simple, clever structure, applicability
Extensively.
