Telescopic curtain guide rail and telescopic method thereof

Abstract

The invention discloses a telescopic curtain guide rail, which comprises an outer rail and an inner rail, and the inner rail is located on one side of the outer rail and embedded in the outer rail; the guide rail also comprises a transmission mechanism, the transmission mechanism comprises a driving wheel, a driven wheel, a first fixed pulley, a second fixed pulley, a belt and a sliding rope, and the belt sequentially passes through the driving wheel, the first fixed pulley, the driven wheel and the second fixed pulley and then is wound back on the driving wheel; one end of the sliding rope is fixedly connected to the outer side of the driven wheel, and the other end of the sliding rope is connected to the interior of the upper end of the outer rail through a third fixed pulley; and when the inner rail slides along the outer rail, the position of the sliding rope located on the outer side of the driven wheel changes, then the position of the driven wheel is driven to change, and it is guaranteed that the belt is in a stretched state. The guide rail is simple in structure, small in occupied area and convenient to stretch out and draw back, standardized batch production can be achieved, and then the production cost is reduced.

Description

technical field [0001] The invention relates to the field of curtain rails, in particular to a retractable curtain rail and a telescopic method thereof. Background technique [0002] Curtain is a kind of household product that is installed at the window to play the role of shading. At present, various rooms have windows with different widths. Therefore, the production of curtain rails needs to measure the width of the window wall first, and then complete the corresponding measurement according to the measurement size. The production of curtain rails. This kind of curtain rail needs to be customized one by one, which cannot realize mass industrial production; and it requires on-site measurement, which wastes manpower and material resources; if there is an error in the measurement or production process, the produced curtain rail may be unusable and need to be reworked. Therefore, the traditional curtain rail adopts a customized method, which is low in efficiency, high in cost...

AI Technical Summary

Problems solved by technology

Since the retractable curtain rails are still in their infancy, the existing retractable rails cannot achieve a smooth transition between the two rails, and even the curtain fabric cannot be switched between the two rails; Set a corresponding variable mechanism to drive the curtain cloth to slide

[0004] At the same time, with the development of automation, the transmission of curtains is more and more practical electric transmission, that is, the motor drives the curtain cloth to move. In this process, the pulley and curtain need to be fixed on the belt through the belt buckle, and then the motor drives The belt buckle, pulley and curtain cloth move together. In the prior art, the belt buckle is fixed on the belt and cannot be effectively disassembled. When the belt buckle needs to be moved, the system needs to be disassembled and dispersed. The operation is cumbersome and inefficient, which reduces the user experience.
