Description

Convenient device bead chain shutter controller structure

The present invention relates to a structure of a roller blind controller for facilitating the bead chain of a device, and more particularly to a roller shutter controller structure capable of facilitating the installation of a bead chain with a simple embedded card concept.

According to the existing roman blinds, blinds, roller blinds and the like, the curtains of the lifting type are provided, and the control of the winding or the hanging of the curtain is provided, and the bead chain controller is used to drive the reel to rotate, so as to achieve the purpose of retracting the curtain body.

Please refer to the "Rolling Curtain Controller Structure Improvement" patent of China Announcement No. M317233. The controller is composed of a fixed seat, a rotating disc, a chain rope, a fixed cover, two limiting springs and a linkage joint. The rear of the fixing base has a cover plate, and a coupling post is arranged at the center. The end of the coupling post is matched with a locking bolt. The outer peripheral edge of the disk is provided with a plurality of engaging grooves, and the center extends inwardly. The sleeve tube has a positioning slot, the chain rope is a continuous ring shape, and is arranged with the engagement groove of the rotating disk, the fixed cover is correspondingly arranged with the fixing seat, and the center is provided with a through hole. The limiting springs respectively extend a limiting leg, and the outer section of the connecting joint extends out of a set of sections, wherein the fixing seat is disposed on the inner side of the cover plate, the coupling column is penetrated by the sleeve tube, and the two limiting springs are worn. It is arranged on the binding column, the limiting foot is located at the positioning missing groove, the chain rope is surrounded by the engaging groove which is hung on the rotating disk, and the fixing cover is covered on the fixing seat to wrap the rotating disk, and the chain rope is fixed by the fixed cover Rotating below the rotating disk The sleeve tube is pierced by the through hole, and the linkage joint is sleeved on the sleeve tube.

When the user purchases the curtain, if the chain of the roller shutter controller is to be assembled on the rotating disk, the screws that are externally locked into the binding post by the interlocking joint are first retracted, and then the components are loosened away by a certain distance. The disc-shaped engaging groove and the fixed cover have a proper gap, and the chain can be placed in the disc-shaped engaging groove, and then assembled and assembled by screws to be locked again. However, the above-mentioned chain assembly is not convenient, and it is necessary to retract the assembly by the screw of the tool screw, and if the assembly is loosened, if the internal components are accidentally dropped, the assembly cannot be assembled smoothly.

In addition, there is also a patent application "Spring Structure Applicable to Rolling Curtain Controller" as disclosed in China's Announcement No. 428468. In this case, the end of the limit rod is axially formed with a groove and a convex portion, and the corresponding convex portion is combined with the outer sleeve. The cover is assembled, so when the drawstring is to be assembled, the carding protrusion can be directly pressed, which is released from the limit cover, so that the components can be loosened away a little distance before the drawstring can be wound around the drawstring . While this structure does not require tool assistance, the disassembled roller blind controller also has the risk of not being able to reassemble the assembly completely.

The creator has also applied for the patent of the "Quick-Assembled Bead Chain Controller" which is published in the announcement No. M496429, which is mainly equipped with a fixed seat, a bead chain turntable, a spring and a sleeve. And the fixing seat, the bead chain turntable, the spring and the sleeve are sequentially integrated into the sleeve, and the sleeve and the fixing seat are respectively formed with a disc body at one end of the fixing seat, and the fixing seat is The upper edge of the disc body has a cover; the disc system of the sleeve is provided with two recessed grooves at the periphery thereof for the two bead chains to be respectively embedded in the two recessed grooves. . The technical feature mainly provides two corresponding recessed grooves at the periphery of the disc body, and the bead chain is embedded by the insert groove to rotate the disc body to achieve the function of assembling the bead chain without disassembling the component.

Today, the creator has once again upheld the rich experience in design, development and practical production of the relevant industry for many years, and specially provides a structure of the roller blind controller that facilitates the installation of the bead chain, in order to achieve better practical value.

The main purpose of the present invention is to provide a roller blind controller structure which is convenient for the bead chain of the device, and more particularly to a roller blind controller structure which can facilitate the bead chain with a simple embedding concept.
