Dual-pushing toothed belt type lifter
The invention discloses a dual-pushing toothed belt type lifter. The dual-pushing toothed belt type lifter comprises a driving mechanism, a lifter support and a lifter base; the dual-pushing toothed belt type lifter is characterized in that the lifter support is a rectangular strip-shaped pipe body, a gap is longitudinally formed in the side wall of the pipe body to form a sliding rail, a rectangular toothed belt guiding groove is formed in the inner wall of the pipe body of the lifter support, a toothed belt which can be vertically pulled and has toughness is arranged in the toothed belt guiding groove, the toothed belt is meshed with a toothed belt driving gear which is arranged on the lifter base arranged at the lower end of the lifter support, and the back surface of the toothed belt in a meshing position is provided with a pressing wheel which can be used for pressing and squeezing the toothed belt. The dual-pushing toothed belt type lifter disclosed by the invention has the beneficial effects that since the back surface of the toothed belt in the meshing position of the toothed belt is provided with a wheel body which can roll, a sliding friction state of the back surface of the toothed belt can be changed into a rolling friction state, the friction resistance can be reduced to large extent, and the disadvantages in the prior art that the abrasion is large, clamping stagnation is easily generated, the fault rate is high, and the service life is short are overcome.
