Toothed belt pulling type self-adaptive sliding block lifter
The invention discloses a toothed belt pulling type self-adaptive sliding block lifter. The toothed belt pulling type self-adaptive sliding block lifter comprises a driving mechanism, a lifter bracket and a lifter base and is characterized in that the lifter bracket is a rectangular strip-shaped pipe, wherein a gap is vertically arranged on the side wall of the pipe to form a sliding rail; a rectangular toothed belt guide slot is formed in the inner wall of the pipe of the lifter bracket; a flexible toothed belt capable of twitching up and down is arranged in the toothed belt guide slot; the toothed belt is meshed with a toothed belt driving gear arranged at the upper end of the lifter bracket on the lifter base and penetrates through a toothed belt tail guide slot; the lower end of the toothed belt is fixedly connected to the sliding block which is clamped in the sliding rail. The toothed belt pulling type self-adaptive sliding block lifter had the beneficial effects that the toothed belt driving gear is arranged at the upper end of the toothed belt, pushing and lifting force applied to the toothed belt by the driving gear is changed into upward pulling force, friction force between the toothed belt and the side wall of the toothed belt guide slot is reduced, a compression spring is used for ejecting a pulley block to move forwards after the sliding block is abraded so as to compensate the abrasion of the sliding block, and the occurrence rate of the fault of the lifter in the using process is reduced.
