Dual-thrust toothed belt type lifter with spring-strip buffering gear and self-adaptive sliding block
A dual-thrust toothed belt type lifter with a spring-strip buffering gear and a self-adaptive sliding block 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 abrasion is reduced; when the sliding block suffers from abrasion, a pressure spring props against a pulley block to move forward so as to compensate the abrasion of the sliding block; 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.
