The invention discloses a driving chair convenient to lift and adjust, which comprises a cushion backrest assembly, safety belts, a slideway, a brake assembly, an upper chute assembly, a lifting assembly and a lower chute assembly, the safety belts are arranged on the left side and the right side of the cushion backrest assembly, and the lower surface of the cushion backrest assembly is connectedwith the upper chute assembly through the slideway; a threaded sleeve in the upper sliding groove assembly is connected with a limiting threaded rod in the brake assembly, a lower sliding groove assembly is arranged below the upper sliding groove assembly, a lifting assembly is arranged between the upper sliding groove assembly and the lower sliding groove assembly, and the lifting locking mechanism is flexible and reliable and can be locked through structural conversion of the limiting threaded rod, a plug pin, the limiting threaded rod and the threaded sleeve. The distance between every twogears is small, locking acting force conversion should be conducted in the vertical direction, stress on the spline at the outer end of the limiting screw is reduced to a large extent, the service life of the locking mechanism is greatly prolonged, and the structural stability of the locking mechanism is greatly improved.
本发明公开了一种方便升降调节的驾驶椅,包括坐垫靠背组件、安全带、滑道、制动组件、上滑槽组件、升降组件和下滑槽组件,所述坐垫靠背组件左右两侧设有安全带,所述坐垫靠背组件下表面通过滑道与上滑槽组件连接,所述上滑槽组件中的螺套与制动组件中限位螺杆连接,所述上滑槽组件下方设有下滑槽组件,所述上滑槽组件和上滑槽组件之间设有升降组件,此升降锁紧机构不仅灵活可靠,而且通过限位螺杆和插销、限位螺杆和螺套结构转换,每档的间距较小,应在垂直方向进行了锁紧作用力转换,很大程度的减小了限位螺杆外端花键处受力,大大提高了锁紧机构的使用寿命及结构稳定性。
