Double-push toothed-belt type spring buffering gear self-adaptation sliding block lifter
A double-push toothed-belt type spring buffering gear self-adaptation sliding block lifter comprises a driving mechanism, a lifter support and a lifter base. The double-push toothed-belt type spring buffering gear self-adaptation sliding block lifter is characterized in that the lifer support is a rectangular long-strip-shaped pipe, a seam is longitudinally formed in the side wall of the pipe to form a sliding rail, a rectangular toothed belt guide groove is formed in the inner pipe wall of the lifter support, a ductile toothed belt capable of being pulled up and down is arranged in the toothed belt guide groove, the toothed belt is meshed with a toothed belt driving gear arranged on the lifter base at the lower end of the lifter support, and a pressing wheel having the pressing, squeezing and pushing action on the toothed belt is arranged on the part, at the meshed position, of the back face of the toothed belt. The double-push toothed-belt type spring buffering gear self-adaptation sliding block lifter has the advantages that due to the fact that a wheel body capable of rolling is arranged on the part, at the meshed position of the toothed belt, of the back face of the toothed belt, abrasion is relieved; when a sliding block is abraded, a press spring can eject a pulley block to move forwards to compensate for the abrasion of the sliding block; the driving gear is a buffering gear, the protection function on the gear is achieved, and thus the service life of the lifer is prolonged.
