Description

Curtain controller structure

The present invention relates to a curtain controller structure, especially a curtain controller structure that can easily assemble the bead chain on the bead chain transposition and can effectively prevent the bead chain from falling off during the operation of the bead chain.

According to the existing curtains such as Roman blinds, jalousie curtains, and roller blinds, the control of the rolling or draping of the curtain body is mainly based on the use of the curtain controller to drive the scroll shaft to achieve the effect of retracting the curtain body. Please refer to "Structure of Roller Blind Controller" in Taiwan Announcement No. M317233. It is a common curtain controller on the market. It mainly consists of a fixed seat, a rotating plate, a chain, a fixed cover, a limit spring and It consists of a joint and so on. When the chain of the roller shutter controller is to be assembled on the rotating disk, it is necessary to first loosen the screws locked by the outside of the joint into the coupling column, and then loosen each component some distance. In order to ensure that there is a proper gap between the rotating disk and the fixed cover, the chain rope can be wound and assembled on the rotating disk, and then fitted and assembled in sequence and locked with screws, so the chain rope assembly method is extremely troublesome and time-consuming.

Therefore, the creator of this case has developed a "roller curtain controller structure for facilitating the installation of a bead chain" in Taiwan Announcement No. M525146, which is mainly provided with a bead chain turntable on the side of the fixed seat, and uses a limit seat to locate the bead chain turntable. And a fixed cover is covered on the outside of the limit seat to protect the bead chain around the bead chain turntable from falling off, and a plurality of snap bars are provided at the outer peripheral end of the limit seat ring, and The fixing cover is provided with a latch groove corresponding to the latching position at the corresponding latching strip. According to this, a simple card inserting technique can be used to facilitate the assembly and positioning of the bead chain. Of course, although the Taiwanese Announcement No. M525146 "Convenient Device Bead Chain Roller Controller Structure" can achieve the effect of convenient device and positioning the bead chain, when using it, it is found that when the bead chain is pulled, if the bead chain is pulled, When the force is applied to deviate from the joint direction of the fixed cover and the fixed base, the bead chain may detach from the joint between the fixed base and the fixed cover, resulting in inconvenience in use.

The reason is that the creator has the above-mentioned shortcomings in the use and implementation of the previously developed "Annual Roller Controller Structure for Convenient Device Bead Chain" of Taiwan Announcement No. M525146, which is based on its many years of manufacturing and design in related fields It is supplemented by experience and knowledge, and through various ingenuity, has created this creation.
