Double-thrust toothed belt type lifter with spring buffering gear
A double-thrust toothed belt type lifter with a spring buffering gear comprises a drive mechanism, a lifter bracket and a lifter base and is characterized in that the lifter bracket is of a rectangular strip-shaped tube body; a seam is formed longitudinally in the side wall of the tube body to form a sliding rail; a rectangular toothed belt guide groove is formed in the internal wall of the tube body of the lifter bracket; and a flexible toothed belt capable of twitching up and down is arranged in the toothed belt guide groove; the toothed belt is engaged with a toothed belt drive gear, which is arranged on the lifter base, at the lower end of the lifter bracket; and a pinch roller for compacting, extruding and pushing the toothed belt is arranged on the back of the toothed belt at the engaged position. The beneficial effects are as follows: the roller body capable of rolling is arranged on the back of the toothed belt at the engaged position of the toothed belt, so that the back of the toothed belt becomes rolling friction from the original sliding friction state and the frictional resistance is reduced greatly; the drive gear is a buffering gear which plays a role in protecting the gear, so that the service life of the lifter is prolonged.
