Abstract
The utility model relates to a buffering chair, which is used for the chair for drivers on tractors. The buffering chair is composed of a seat cushion, a backrest cushion, a guard plate, a base, a movable shelf, a bracket, and an adjustable supporting seat. The buffering chair is characterized in that a main spring and an auxiliary spring are arranged on the buffering chair. The centers of the main and the auxiliary springs are on the same straight line, and are perpendicular to a ground. In addition, a pair of pulleys are arranged. When the seat cushion and the backrest cushion are floated with the main and the auxiliary springs, the pulleys play the function of guiding up and down. When the tractors travel and bring a vibration, the very large buffering function can be played. Thus, the drivers can sit stably. The buffering chair has the advantages of simple structure, low cost, and easy maintenance and repair.
Description
The utility model relates to a kind of buffer armchair, is used for doing on the trac. seat of chaufeur.
In the seat of existing operator on the tractor, utilize two extension springs and damping oil cylinder to come vibration damping, though buffering effect is arranged, but it is in use not ideal enough, to be trac. made transportation means to its shortcoming when running ground through uneven on road, the oily flow velocity degree of damping oil cylinder often is lower than the advance speed of (or jump off down scurry) of trac., this is because the speed of advance of trac. causes vibration and vibration to cause with it application force is synchronous, and the effort that causes with vibration is to damping oil cylinder, make the shock damping action power of mobile generation of its oil asynchronous, in addition, damping oil cylinder manufacturing cost height, maintenance trouble.In order to overcome the above problems, task of the present utility model provides a kind of being quick on the draw, the buffer armchair of good damping result.
The utility model is achieved in that and is provided with backrest cushion, baffle plate, pedestal, tressel, pulley, adjustable support seat and guard shield in the back backrest of seat, only be provided with support, cushion in the seat of seat.Backrest cushion is fixed on the backup plate front in the tressel, cushion is fixed on the plane that wide head rod in the support and the brachycephaly group in two bent angle link rods form, support can rotate around the minor axis of the pedestal of packing into, pedestal is fixed on the base of operator's saddle, it is characterized in that: the long end of bent angle link rod is fixed on the tressel, a main spring and an auxiliary spring are housed on pedestal and tressel and adjustable support seat, and a pair of pulley, the line of centers of main spring and auxiliary spring is on same straight line, and vertical ground all is a stage clip.Be inserted in the main unsprung axle seat of the adjustable support seat that combines as a whole with pedestal the lower end of main spring, and be inserted in the main sprung axle seat in the tressel upper end of main spring.Axle bed under the auxiliary spring in the tressel is inserted at the adjustable auxiliary spring seat of honour up and down in the middle of be inserted in above the guard shield upper end of auxiliary spring, auxiliary spring lower end.Guard shield is fixed as one with pedestal again.Pulley is fixed on the tressel, can slide on the slide plate in pedestal, and when cushion and backrest cushion during with the floating of main spring and auxiliary spring, pulley slides up and down and play the guiding role.When being vibrated, can produce good buffer action, thereby chaufeur is occupied stably.
The utility model is mainly the welding support structure, compares with known buffer armchair, and its advantage is: simple in structure, easy to manufacture, cost is low, good buffer effect, and maintenance is easily.
Be described further below in conjunction with embodiment of the present utility model.
