Abstract
A tooth-belt-lifting type elastic piece buffering gear lifter comprises a driving mechanism, a lifter support and a lifter base. The lifter is characterized in that the lifter support is a rectangular long-strip-shaped pipe body, a gap is longitudinally formed in the side wall of the pipe body to form a sliding track, a rectangular tooth-belt guiding groove is formed in the inner wall of the pipe body of the lifter support, a tooth belt which can twitch up and down and has tenacity is arranged in the tooth-belt guiding groove, the tooth belt is meshed with a tooth belt driving gear which is arranged on the lifter base at the upper end of the lifter support, the tooth-belt driving gear is inserted into the guiding groove in the tail of the tooth belt in a penetrating mode, and the lower end of the tooth belt is fixedly connected with a sliding block clamped into the sliding track. The tooth-belt-lifting type elastic piece buffering gear lifter has the advantages that the tooth-belt driving gear is arranged at the upper end of the tooth belt, so that the pushing force on the tooth belt from the driving gear is changed to upward lifting force, friction force between the tooth belt and the side wall of the tooth-belt guiding groove is lowered, the shortcoming that in the prior art, abrasion is high, and blocking can happen easily is overcome, the driving gear is a buffering gear, the gear is protected, and the service life of the lifter is prolonged.
