Description

Rolling shutter linkage trailer structure

The present invention relates to a roller blind linkage trailer structure, in particular to a fixture structure that can be fitted with two wall surfaces of different angles to connect adjacent double-layer roller blinds.

At present, the roller blind structure generally used, such as the new type M307681 "roller reel transfer structure" patent announced by the Republic of China on March 11, 1996, discloses that it includes a steering gear, at least one fixing frame, The steering gear includes a first pivoting portion, a second pivoting portion, and at least one universal joint, and the first pivoting portion and the second pivoting portion are connected by a universal joint, and the fixed frame is provided The shaft hole is corresponding to the pivoting steering gear. In this way, the first pivoting portion and the second pivoting portion of the steering gear are interlocked with each other so that the linkage of the roller reel at the corner of the wall or the ceiling is not limited by the angle of the corner, and the transmission force is more reliable. .

Although the patent has a universal joint, it can be installed with a wall with a certain range of angles. However, once it is used in a double-layer roller blind, it is necessary to install two sets of rolling mechanisms at the same time. The double-layered roller blind is therefore time consuming to install and increases manufacturing costs.

Therefore, there is a new type of M300511 "double roller blind structure" patent announced by the Republic of China on November 11, 1995, which discloses: a first bracket, a second bracket, and a first bracket mounted thereon a control mechanism inside and rotatably a first roller blind group and a second roller blind group installed between the two brackets; wherein the steering mechanism comprises a first wheel and a second wheel, the first wheel and the second wheel train are individually and mutually formed Reversely driving the reel of the first roller blind group and the reel of the second roller blind group, and the curtains of the first roller blind group and the second roller blind group are substantially transparent and substantially less The light-transmissive cloth is made, and the position of the curtain of the two roller shutter sets can be arbitrarily controlled by the user to adjust the transmittance of the entire roller blind.

However, in such a configuration, once the wall surface having the angle is encountered, a scrolling mechanism must be provided on each wall surface to drive the roller blind on each wall surface for lifting movement, so the installation is quite Inconvenient and costly, it is still not ideal for use.

Therefore, in view of the current rolling installation structure of the double-layer roller blind, which has the above-mentioned disadvantages in use, the present invention provides a roller blind linkage trailer structure, which is provided with a fixing base which is provided with a first fixing.
