Embodiment 1

[0032] In order to solve the technical problem that a user's hand or a child is easily drawn and involved in an existing rolling shutter door, which causes a great safety accident and thus has a great potential safety hazard. Embodiment 1 of the present invention provides a roller blind device, such as Figure 1 to Figure 3 As shown, it includes a roller shade shaft 1, a rolling housing 2, a rolling shade 3, a rolling shade base 4, and a rolling shade frame 5. The rolling shade shaft 1 is flatly arranged in the rolling housing 2, and the rolling shade Rolled on the roller shade shaft 1, the roller shade frame 5 is arranged symmetrically on both sides of the rolling housing 2, and the rolling shade base 4 is embedded on the ground correspondingly to the upper and lower sides of the rolling housing 2.

[0033] like figure 2 As shown, the shutter shaft 1 is horizontally arranged in the winding housing 2, and one end thereof is provided with a power rotation driving part 6, and ...

Abstract

The invention discloses a roller blind device, which comprises a power rotary drive part arranged at one end of the roller blind shaft, the power output shaft of the power rotary drive part is coaxial with the corresponding end of the roller blind shaft through a coaxially arranged first gear Set the second gear mesh setting. Through the power rotation driving part, the gear assembly drives the roller blind shaft to perform the rotation action of winding and unwinding, and the uniform speed control of the roller blind shaft is realized by using the corresponding cooperation between the convex teeth and the tooth grooves of the gear, and then the roller blind shaft is aligned with the rolling motion. The curtain is rolled or unrolled at a constant speed to avoid the danger of people being driven into it when the curtain is rolled too fast.

Description

technical field [0001] The invention relates to a roller blind device. Background technique [0002] The rolling shutter door is connected in series with multi-joint movable curtains, installed in the side track, and the upper and lower doors are rotated around the reel above the door. High performance, suitable for commercial facades, garages, shopping malls, hospitals, industrial and mining enterprises and other public places or residences. However, the existing rolling shutter door usually adopts the automatic rolling deformation elastic force of the torsion spring to realize the rolling of the rolling shutter. Children are driven to be involved, and these are all very serious accidents, so there is a great potential safety hazard in the existing rolling doors. Contents of the invention [0003] The present invention aims at the problems existing in the prior art, and provides a rolling shutter device, which solves the technical problem that the existing rolling shutt...
