Abstract

The invention relates to a rolling blind which at least comprises an upper rail, a lower rail, a rolling blind group, an automatic rolling device and a fixing seat, wherein one side of the upper rail is connected with the automatic rolling device and the other side is connected with the fixing seat, the automatic rolling device consists of a first cover group and a first drive group pivoted with the inner part of the first cover group, and forms the drive by an electric element, and a protruding shaft at the other side of the first drive group is embedded with one side of a shaft lever of therolling blind group; and the fixing seat is embedded with the other side of shaft lever of the rolling blind to form the drive, therefore, the invention can control the rolling and the spreading of the rolling blind through the rotation of the automatic rolling device, and is beneficial to a user to more conveniently roll or unroll.

Description

technical field [0001] The present invention relates to a roller blind, in particular to a roller blind equipped with an automatic retracting device on one side of the upper rail to control the retracting and unfolding of the roller blind, and to provide users with the convenience of retracting or unfolding the curtain. roller blinds. Background technique [0002] Nowadays, there are many styles of curtain structures on the market, such as: venetian blinds, pleated curtains, Roman curtains, etc., which are mainly installed on the doors and windows of homes to shield sunlight and The function of decoration, and according to the needs of different consumers, the general curtain can be divided into the need to use the pull cord to rise or fall to control its rolling and unfolding action. For the single-width sheet type curtain 10, it is more to adopt the curtain rolling buffer device 11 (such as figure 1 shown). The curtain retracting buffer device 11 is mainly composed of a...
