Abstract: Disclosed in the disclosure is a wind spring coiling apparatus with a wind spring built in an upper beam, including an upper beam and a bracket. A reel is mounted on the bracket. The coiling apparatus includes a wind spring, fixed discs and a coiling disc, the wind spring being sleeved on the fixed discs, and a coiling end of the wind spring being clamped with the coiling disc; and an adjusting plunger, one end of the adjusting plunger being in transmission connection with the coiling disc, and the other end of the adjusting plunger being connected with the reel through a transmission structure. By mounting a coiling apparatus in the prior art in an upper beam, the widths of a left bracket and a right bracket in the prior art can be greatly reduced, thereby being more suitable for blinds with narrower brackets and small face widths.

Abstract: The Invention relates to the field of roller shutter, discloses the automatic landing or rising type roller shutter, the main point of its technical solution is to include the shell, the shell is set with a disc, the side of the shell is set with an extension tube, the side of the disc is set with an extension body, at least part of the extension body extends into the extension tube, through the user pulling the rope body, drive the roller shutter rise or fall, in each with any start-stop structure or can advance to apply the force of the spring roller shutter. The rope body is provided with a pull rod in the part of the rope body that extends out of the shell, and the rope body is pulled by the pull rod to facilitate the user's grip and prevent the rope body from knotting and other situations.

Abstract: A roller blind driving device with a motor in an upper beam, the upper beam has a containing cavity, the motor and a pipe coiler body. The motor is installed in the containing cavity of the upper beam; the installation location of the motor in the prior art is improved as the interior of the containing cavity of the upper beam, and the motor is in transmission connection with the pipe coiler body through the transmission structure, so as to apply to pipe coiler bodies with various specifications. The motor with single volume is adopted to reduce the cost of manufacturers.

Abstract: A spring roller blind which can be started and stopped at will, including a transverse rod and a chuck, wherein the transverse rod is fixedly connected to the chuck, a first torsion spring is arranged on the transverse rod, and one end of the first torsion spring is fixedly connected to one end of the transverse rod away from the chuck. When pulled downwards, the roller blind can be stopped at any position by the friction between embracing springs and a pipe plug; and when a pull ring is pulled, the roller blind can be retracted automatically under the action of the restoring force of the first torsion spring.

Abstract: A pre-loadable spring roller blind, including a spring bar, a limiting spring, a spring tail plug and a limiting pipe plug sleeve. By arranging the spring tail plug into the first rotating plug and the first adjusting core and arranging the holding spring between the first rotating plug and the first adjusting core, the first adjusting core can be rotated to store the force for the limiting spring. After the torsion force is stored, the spring may not discharge the force when released. When the limiting pipe plug sleeve is used for loading, as long as the tail of the spring bar is fixed, the limiting pipe plug sleeve is rotated to store a force for the limiting spring. After the force is stored, the limiting pipe plug sleeve can be released at any time and the limiting pipe plug sleeve is kept fixed.

Abstract: The utility model discloses a hand-held narrow-edge zebra curtain, comprising a left bracket, a right bracket corresponding to the left bracket, and a pylon connected to the left bracket and the right bracket, wherein a scroll is arranged on the left bracket and the right bracket; a roller blind is arranged on the scroll; and coiling apparatuses used for coiling the scroll are respectively arranged on the left bracket and the right bracket. The zebra curtain of the present application realizes torsion presetting by installing leaf springs, thereby regulating the contraction torque of the scroll and completely receiving the curtain. Furthermore, by adopting the zebra curtain with this design, a side cap of the zebra curtain can be designed to be much narrower than that of a conventional zebra curtain, so as to the curtain fabric can be made wider to less light leakage on the side.
