Description
Technical field
The invention belongs to engineering automobile seat field, have and relate to a kind of engineering automobile seat handrail.
Background technology
Engineering truck is the trunk strength of a building engineering, because their appearance just makes the progress multiplication of building engineering, has greatly reduced manpower.See engineering truck operation, can't help and make people shake machine and scientific and technological power.They excavate for the delivery of engineering, and repairing is even fought etc.Common engineering truck has: heavy goods vehicle, large-scale crane, excavating machine, bulldozer, roller, load wagon, electric power rush-repair vehicle, breakdown lorry, government's special purpose engineering automobile, cross-country engineering truck, electric welding engineering truck, armored engineering vehicle (combat engineer vehicle), oxidizer sewage treatment project car etc.Engineering automobile seat handrail of the prior art is non-adjustable, and the head driver time is used easily tired, and production efficiency is not high.
Therefore, need a kind of new engineering automobile seat adjustable handrail to address the above problem.
Summary of the invention
Goal of the invention: the present invention is directed to the uncontrollable defect of engineering automobile seat surface height in prior art, a kind of engineering automobile seat adjustable handrail is provided.
Technical scheme: for solving the problems of the technologies described above, engineering automobile seat adjustable handrail of the present invention adopts following technical scheme:
A kind of engineering automobile seat adjustable handrail, comprise handrail seat board, described handrail seat board is fixed on the backrest frames of engineering automobile seat, also comprise handrail body, handrail axle, stop screw, regulate screw mandrel, regulating handle and nut inserts, described handrail axle is fixed on described handrail seat board, described handrail body and described handrail axle are hinged, described stop screw is arranged on described handrail axle, in described handrail body, be provided with described nut inserts, described adjusting screw mandrel is arranged in described handrail body and through described nut inserts, described adjusting screw mandrel matches with described nut inserts, the relatively described handrail body motion of described adjusting screw mandrel, one end of described adjusting screw mandrel described stop screw of conflicting, the other end of described adjusting screw mandrel is provided with described regulating handle.
Beneficial effect: handrail body and handrail axle are hinged, can rotate around handrail axle.Regulate screw mandrel to be installed in handrail body through via hole, and be connected cooperation with nut inserts in handrail body.Rotate regulating handle and drive the rotation of adjusting screw mandrel, and then can make to regulate screw mandrel sway by fixing nut inserts.When regulating screw mandrel to touch stop screw, handrail just can not rotate around handrail axle, namely spacing fixing, like this, just can be reached and be made handrail body in the fixing object of diverse location by rotation regulating handle.Engineering automobile seat adjustable handrail of the present invention is simple in structure, can realize very easily armrest positions and regulate.
