Belt type adaptive slide block hoist
The invention discloses a belt type adaptive slide block hoist. The hoist comprises a driving mechanism and a hoist bracket, and is characterized in that the upper and lower ends of the strip-shaped hoist bracket are provided with a transmission belt driven gear and a transmission belt driving gear respectively and are connected by a toothed belt with a tooth hole for transmission, wherein the hoist bracket is provided with an isolation sheet for isolating a front belt from a rear belt of the transmission belt; the front belt is fixedly provided with a slide block for mounting vehicle window glass; a sliding chute of the slide block is clamped on a slide rail of the hoist bracket; a transmission belt driving gear shaft is connected with the driving mechanism. The hoist has the beneficial effects that the contact area of the transmission belt and the transmission gear of the hoist is large; the stress points are scattered; the defects that the contact area of a steel wire of a rope wheel type automobile window hoist and the transmission wheel is small, the stress points are concentrated and the wear is serious are avoided; a pulley set is pushed to move forwards by a hold-down spring to compensate wear of the slide block after the slide block is worn, so that the occurrence rate of faults during use of the hoist is reduced.
