Curtain telescopic rail

Abstract

The invention discloses a curtain telescopic rail. A customer can control expansion amount of a cyclo-conveyor belt between a driving wheel and a guide wheel and the expansion amount of the cyclo-conveyor belt between a first fixed pulley and a second fixed pulley as own required, so that an inner guide rail can perform expansion along an outer guide rail, the guide rail length is adjusted, and the adaptability and the usability are extremely high; by arranging the cyclo-conveyor belt as a belt segment and a cord segment the driving wheel is driven through the belt segment, the driving error and blocking are reduced, the problems of the easy slipping of the driving wheel and the cord and the expansion and the limited driving are solved, and the torque can be accurately transmitted. And thetelescopic rail can be used for the field of the curtain.

Description

technical field [0001] The invention relates to the field of curtains, in particular to a curtain telescopic rail. Background technique [0002] Curtain is a kind of household item installed on the window to play a blocking role.
