Abstract
The utility model provides a structure is highly adjusted to lever seat, it is including lift post, poppet, control lever, and wherein, the poppet is the U -shaped, and the outside level in U -shaped both sides lateral wall top is extended and is formed fixed limit, should pass through the fixed present rebasing portion of fixing bolt in fixed limit, leans against the frame and fixes the wherein one side lateral wall outside at the poppet, U -shaped bottom is fixed in lift capital portion, and U -shaped bottom center department opens has the through -hole, and the relief valve of lift capital portion passes through -hole and the contact of control lever one end, and control lever pole body is equipped with the conflict end of flat form through the present rebasing portion of a hinge movable mounting, control lever one end, should contradict the end position directly over the relief valve, and the bottom of a matter portion of contradicting contacts with the relief valve top, bends and extend to seatpad edge formation control end in the outside below of the control lever other end. Simple structure has after this scheme of adoption, convenient operation, control effectual, long service life's advantage.
Description
Technical field
This utility model relates to chair lift technical field, refers in particular to lever height of seat adjustment structure.
Background technology
Chair lift is a general call, refers to the swivel chair that seat height is the most adjustable, seat can horizontally rotate, and people generally also call it by titles such as rotary lifting chair, swivel chair, computer chair, office chairs.Due to have below the seat of this seat one for regulate height lowering or hoisting gear, so seat can be with oscilaltion.Being vapour-pressure type or fluid pressure type according to lowering or hoisting gear used, chair lift is divided into pressure liftable chair and two kinds of hydraulic lifting chair.At present, the lowering or hoisting gear that chair lift on the market uses is divided into 3 class oil pressure, mechanical type and air pressure.In the majority with air pressure in the chair lift of low side.Individual cylinder is had in Pneumatic type lifting chair, piston air-leg in cylinder moves up and down and arranges chair lifting, lifting part has following characteristic: the when of pressing that lift valve door trip: people takes, namely give lifting shaft pressure, lifting shaft the most gently declines, speed is uniform, can bottom out.Not giving lifting shaft external force, lifting shaft bounces back into peak at once, the when of not by (or by midway unclamp) valve switch: lifting shaft remains in current location, compresses and it all can not be made to move relative to outer sleeve with stretching.If this control mode people does not takes, then cannot realize the function of lifting, and this kind of control device is easily damaged, service life is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to operate, control effective, the lever height of seat adjustment structure of length in service life.
For achieving the above object, technical scheme provided by the utility model is: lever height of seat adjustment structure, it includes lifting column, poppet, control bar, wherein, poppet is U-shaped, U-shaped both sides top side wall is extended outward horizontally so as to form fixed edge, and this fixed edge is bolted to bottom seat cushion by fixing, leans against frame and is fixed on the wherein side side-wall outer side of poppet；Lifting column top it is fixed on bottom U-shaped, through hole is had at U-shaped bottom centre, the relief valve at lifting column top is through through hole and control bar end thereof contacts, control club body and be movably arranged on bottom seat cushion by hinge part, control bar one end and be provided with flat flat-shaped conflict end, this conflict end is positioned at directly over relief valve, and conflict bottom portion contacts with relief valve top, controls the bar other end and to outer lower side bending and extends to be formed at external edge control end.
Described hinge part is fixed on bottom seat cushion, is provided with the U-shaped hinge groove downwardly extended, controls club body and be movably articulated in this hinge groove by bearing pin in the middle part of hinge part.
This utility model is using after such scheme, when dialing up control end, controls bar with bearing pin as fulcrum, controls relief valve by conflict end and realize the lifting of seat cushion, will lean against frame and be fixed on poppet side and make installation more convenient；Use after this programme and there is simple in construction, easy to operate, control effective, service life length advantage.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, lever height of seat adjustment structure described in the present embodiment includes lifting column 1, poppet 2, controls bar 3, wherein, poppet 2 is U-shaped, U-shaped both sides top side wall is extended outward horizontally so as to form fixed edge, and this fixed edge is bolted to bottom seat cushion 4 by fixing, leans against frame 7 and is fixed on the wherein side side-wall outer side of poppet 2；Lifting column 1 top it is fixed on bottom U-shaped, through hole is had at U-shaped bottom centre, the relief valve 5 at lifting column 1 top is through through hole and control bar 3 end thereof contacts, control bar 3 shaft and be movably arranged on bottom seat cushion 4 by hinge part 6, described hinge part 6 is fixed on bottom seat cushion 4, the U-shaped hinge groove downwardly extended it is provided with in the middle part of hinge part 6, control bar 3 shaft to be movably articulated in this hinge groove by bearing pin, control bar 3 one end and be provided with flat flat-shaped conflict end, this conflict end is positioned at directly over relief valve 5, conflict bottom portion contacts with relief valve 5 top, control bar 3 other end and to outer lower side bending and extend to seat cushion 4 edge formation control end.The present embodiment, when dialing up control end, controls bar with bearing pin as fulcrum, controls relief valve by conflict end and realize the lifting of seat cushion, will lean against frame and be fixed on poppet side and make installation more convenient.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
