Abstract
The invention discloses an adjustable backrest of a seat for engineering machinery. The adjustable backrest comprises a backrest bracket and a back cushion, wherein the backrest bracket is a telescopic cylinder with adjustable thickness, and the back cushion is a foldable separated spongy cushion, the adjustable backrest of the seat for engineering machinery has is simple in structure and convenient to use. By the implementation of the invention, the phenomenon that the length of the backrest in the prior art is fixed can be changed, the length of the backrest can be changed freely, and the adjustable backrest provided by the invention has good stability and can meet use demands.
Description
Technical field
The present invention relates to a kind of seat, be specifically related to the scalable backrest of a kind of engineering machinery with seat.
Background technology
At present, seat is comparatively common, in technical field of engineering machinery, uses also relatively extensively.The seat that uses in the technical field of engineering machinery adopts old-fashioned structure, can not regulate during backrest length; To the people of different stature length, can not play good effect, especially aspect neck protection; That does is not enough especially, is unfavorable for the use of human pilot.
Summary of the invention
Goal of the invention: the deficiency to existing in the prior art the purpose of this invention is to provide the scalable backrest of a kind of engineering machinery with seat, with realization to the adjusting of handrail length freely.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopts is:
A kind of engineering machinery comprises back bracket and backing cushion with the scalable backrest of seat, and described back bracket is the retracting cylinder of adjustable length, and described backing cushion is folding piecemeal foam-rubber cushion.
Described retracting cylinder is provided with regulating handle and the fixture that cooperatively interacts and use.
Scalable backrest of the present invention, simplicity of design is through regulating the length of back bracket and fixing; And the folding adjusting that combines backing cushion; Be fit to the human pilot of different stature height, the protection of especially many necks plays a good role; Change the unalterable phenomenon of the length of backrest in the prior art, very convenient to use.
Beneficial effect: engineering machinery of the present invention is with the scalable backrest of seat, and is simple in structure, easy to use; Changed the unalterable phenomenon of the length of backrest in the prior art; The adjusting of realization backrest length has good stability freely, can satisfy user demand.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is done further explanation.
A kind of engineering machinery comprises back bracket and backing cushion with the scalable backrest of seat, and described back bracket is the retracting cylinder of adjustable length, and described backing cushion is folding piecemeal foam-rubber cushion.
Described retracting cylinder is provided with regulating handle and the fixture that cooperatively interacts and use.
Scalable backrest of the present invention, simplicity of design is through regulating the length of back bracket and fixing; And the folding adjusting that combines backing cushion; Be fit to the human pilot of different stature height, the protection of especially many necks plays a good role; Change the unalterable phenomenon of the length of backrest in the prior art, very convenient to use.
Engineering machinery of the present invention is with the scalable backrest of seat, and is simple in structure, easy to use, changed the unalterable phenomenon of the length of backrest in the prior art, and the adjusting of realization backrest length has good stability freely, can satisfy user demand.
