Abstract: The present invention relates to a roller blind and a control device thereof. The control device comprises a reeling mechanism, a solenoid valve, a push mechanism, a front cap, and a damper. After the solenoid valve is energized, the solenoid valve drives the push mechanism to push against the front cap so as to separate the front cap from an engaging portion of the reeling mechanism, and the reeling mechanism is not subject to a resistance of the damper. A curtain fabric is not affected by the resistance of the damper and can be quickly lowered by gravity.

Abstract: Disclosed is a roller blind allowing an upper position limit and a lower position limit to be set by the damper of the roller blind. The damper allows the upper position limit and the lower position limit to be set and includes an inner tube, a first sliding base, a first position-limiting base, and a second position-limiting base. When a blind fabric is driven by a linkage assembly, the first sliding base is driven by the linkage assembly and ends up pushed against the first position-limiting base or the second position-limiting base to stop the linkage assembly from driving the blind fabric. The blind fabric can therefore be limited in position whether it is raised or lowered.

Abstract: A roller and an insert plate-assisted roller securing device are provided. The insert plate-assisted roller securing device includes a wheel-shaped cover, an outer cover, and a bracket. The outer cover has a supported portion with different widths in different directions, and the supported portion can be engaged in the bracket without separating from the bracket. As the outer cover can be coupled to the bracket along with the roller by a single person, installation of the roller is made easier and less time-consuming than before.

Abstract: A reel-linking structure and a linking collar thereof are disclosed. The reel-linking structure includes a mount, two reel connectors, and the linking collar. At least one of the two reel connectors is rotatably connected to the mount. The linking collar has two arms between which an encircled space is defined and configured to connect between the two reel connectors. The two arms are detachably assembled, so that the linking collar can be adjusted between an engaged position and a disengaged position. At the engaged position, the two reel connectors are motionally linked. At the disengaged position, the two reel connectors are motionally delinked.
