Curtain telescopic guide rail

Abstract

The invention provides a curtain telescopic guide rail. The guide rail comprises an inner guide rail, an outer guide rail, a first rotating wheel, a second rotating wheel, a conveyor belt and a curtain guide rail pulley, wherein one end of the inner guide rail is nested in the outer guide rail, and the inner guide rail and the outer guide rail can slide relatively in a telescopic manner; the first rotating wheel and the second rotating wheel are installed at the two ends of the curtain telescopic guide rail respectively; the conveying belt is annular and sleeves the outer sides of the first rotating wheel and the second rotating wheel; the conveying belt is connected between the first rotating wheel and the second rotating wheel, the first rotating wheel and the second rotating wheel are in transmission connection, the conveying belt is located in the outer guide rail and the inner guide rail, the curtain guide rail pulley is connected with the conveying belt and extends out of the outer guide rail and the inner guide rail, and the guide rail pulley can be driven by the conveying belt to move in the axial direction of the outer guide rail and the inner guide rail; the length of a belt or a rope in the curtain guide rail can be conveniently adjusted through a threading through hole in the guide rail pulley; a plurality of groups of pulleys are arranged so that the tackle can run smoothly in the transverse direction and the longitudinal direction; and the guide rail fixing device can conveniently adjust the length of the telescopic rod guide rail.

Description

technical field [0001] The invention belongs to the technical field of curtains, and in particular relates to a curtain telescopic guide rail. Background technique [0002] At present, most of the curtain rails on the market need to measure the size first and then produce according to the size or refit by professionals in specific applications. The custom production cycle is long, which causes inconvenience to the installation of curtain rods and is easy to cause curtain rods. The waste in the cutting of the rod; and once the length of the curtain rail is determined, it can only be used on the corresponding window. Once the size of the window is changed due to decoration or other reasons, the original size of the curtain rail will not be able to continue to be used. Adjust, generate waste. Adopting the curtain telescopic rod guide rail can well solve the above problems in this regard. However, the use of telescopic rod guide rails also needs to solve the problem of how to ...

AI Technical Summary

Problems solved by technology

Therefore, curtains such as telescopic guide rails, pulley mechanisms and electric mechanisms generally have ropes and timing belts to achieve functions such as telescopic, time-saving and labor-saving opening and closing of the curtains, etc. The inner length is difficult to adjust. If another adjustment mechanism is provided, the structural complexity of the curtain rail will be increased and the size of the curtain rail will become larger, which is not conducive to practical application and product appearance.
