Rope wheel type glass lifting device

Abstract

The invention discloses a rope wheel type glass lifting device which comprises a plastic guide rail, a traction steel wire, a guide block and a drive motor. A guide wheel is mounted at the top of theplastic guide rail. A cylindrical supporting boss is mounted at the bottom of the plastic guide rail. Two square grooves are fixedly formed in the outer portion of the cylindrical supporting boss. Theguide block is overall in an arc shape. A clamping groove cooperating with the cylindrical supporting boss is formed in the inner side of the guide block. A traction steel wire guide groove is formedin the outer side wall of the guide block. Inverted buckles are arranged at the two ends of the inner side of the guide block. The drive motor and a wire winding wheel driven by the drive motor to rotate are mounted in the middle of the plastic guide rail. The traction steel wire is wound in a spiral wire groove of the wire winding wheel, the top of the traction steel wire is wound around the guide wheel, and the bottom of the traction steel wire is wound around the guide block. A glass bracket is fixedly mounted on the traction steel wire, and glass is mounted on the glass bracket in a cooperation manner. According to the rope wheel type glass lifting device, the guide block is adopted for replacing a guide wheel structure at the middle lower end of a traditional guide rail structure, and the advantages that the integration degree is high, lightweight is achieved, the structure is simple, and assembly is easy are achieved.

Description

technical field [0001] The invention relates to the technical field of window lifters, in particular to a rope wheel type glass lifter. Background technique [0002] The rope wheel electric window lifter is the most widely used window control mechanism at present. It is mainly composed of a window motor, a rope part, a winding drum, a guide rail, a guide wheel, and a glass bracket. When the window motor rotates clockwise or counterclockwise, the motor drives the worm gear to drive the reel to rotate forward or reversely; Moving up and down along the guide rail, the glass fixedly connected with the glass bracket also moves synchronously thereupon to realize the rising and falling of the window glass. [0003] The guide wheel is riveted on a metal bracket through a hollow rivet, and then the guide wheel, the hollow rivet and the metal bracket are fastened on the mounting hole of the plastic guide rail as a whole through self-tapping screws. The rope pulley electric glass reg...

AI Technical Summary

Problems solved by technology

The traditional structure uses guide wheels at the upper and lower ends of the guide rail. Not only is the assembly process complicated, but many parts are used, but also the weight is high and the cost is high.

The state of the window glass is more in a closed state. At this time, the lower wire rope of the lifter is in a loose state, and the traction force acting on the guide wheel at the lower end of the guide rail is very small, and the lower wire rope is easy to slip from the lower end of the guide wheel. out, causing the glass elevator to fail
