Description
The utility model relates to a kind of locomotive seat, i.e. locomotive shock absorbing seat.
The compacting of base plate and bracing frame forms in the prior art, slideway is arranged on the bracing frame, with fixing vertical being put within the slideway of the parallel slide block of two couples of the chair back, the weight of whole seat is drawn by two two tension springs that are suspended on the cross-arm, this cross-arm is controlled by an adjusting screw(rod) that is fixed on cantilever tip again, so just can regulate the height of seat, the pull bar on both sides prevents to swing below the seat.Existing shortcoming is that slideway is gapped, swings big all around, the stress point of whole load has so just produced two kinds of different power near two groups of slide blocks on the chair back, slideway is worn and torn easily, chair back frangibility, because the elastic force of spring is identical, and people's weight difference, though can heighten low, but can not transfer weight, therefore spring is easily broken, and the cost height, and service life is short.
Its purpose of the utility model is: a kind of locomotive shock absorbing seat is provided, it changes slideway into slide shaft, seat height weight is adjustable, thereby good stability, and increased oil leab, utilize lever principle that stress point is transferred to forward position, seat bottom, stressed and the vibration damping of spring back-pressure, thereby the name cushioning performance improves greatly, has reduced cost, has prolonged service life.
The utility model is achieved in that
A kind of locomotive shock absorbing seat comprises: chair frame, seat support, backrest is characterized in that: is with sliding sleeve in the middle of two jiaos of ends of its chair frame base pillar that is fixedly connected, pillar, the top is fixedly connected by the chair back of bearing carrier ring and chair frame; Its stage clip is placed in axis, and axis is a two-semiaxle, and semiaxis is hinged by the back plate of bearing pin and bearing carrier ring on the axis, and semiaxis is hinged by bearing pin and rocker down for it, and spring is fixed by last lower spring cup, and the rocker top is the roller wheel; Bearing support is fixed on the chair frame base, and its rocker is arranged on the interior axle of U groove of bearing support, and seat support is fixed on the connecting panel by screw thread, and backrest is positioned on the seat cushion of seat support.
The expansion plate of its rocker for regulating by slotted hole, sliding sleeve.
Its bearing support is slide block and slideway, worm gear and worm mechanism, and its slideway, worm screw all are fixed on the chair frame.
Its chair frame is a body L type, split type: by the base and the chair back is dustpan-shapedly to combine as a whole by screw thread.
Its bearing carrier ring upper end is provided with oil nozzle.
It is simple in structure, with low cost for the utility model, and cushioning performance is good, and chaufeur is seated and stablizes comfortablely, improves its service life simultaneously.
