Embodiment Construction

[0014] refer to figure 1 and figure 2 , the present invention provides an automatic rising roller shutter retarder, including a retarder main body 10, a clutch mechanism 20 and a transmission mechanism 30.

[0015] The retarder main body 10 includes a retarder casing 11 and a retarder core 12. One end of the retarder casing 11 has a protruding shaft 11-1, one end of the retarder casing 11 has a protruding shaft 11-1, and the other end of the retarder casing 11 has a The container 11-2 has a convex-concave ring 11-2-1 inside the container 11-2. One end of the retarder core 12 has a convex-concave ring 12-1 that fits with the convex-concave ring 11-2-1. The main body of the retarder There is also a sealing cover 13 on one side, and the sealing cover 13 is connected with the retarder housing 11 by screws 14. The sealing cover 13 makes the chamber 11-2 of the retarder housing 11 form a closed space. The chamber 11-2 of the device housing 11 is filled with damping oil.

Abstract

The invention discloses an automatic lifting roller blind retarder comprising a retarder main body, an clutch mechanism and a transmission mechanism, wherein one end of the retarder main body is connected with the clutch mechanism; the other end of the clutch mechanism is connected with the transmission mechanism; the other end of the transmission mechanism is connected with a curtain roller and can rotate coaxially along with the curtain roller. When a curtain is rolled, the clutch mechanism ensures that the transmission mechanism is connected with the retarder main body, and thus, the braking force generated by the retarder main body is transmitted to the transmission mechanism and the curtain roller; and when the roller blind is unfolded, the clutch mechanism ensures that the transmission mechanism is disconnected with the retarder main body. The automatic lifting roller blind retarder is simple in structure, reliable in operation and low in manufacturing cost, generates the braking force when the curtain is rolled, further reduces the impact sound when the curtain is rolled, particularly when the rolling is about to end, and does not increase the drawing force when the curtain is unfolded, therefore, the service stability and service life of the curtain are improved.

Description

technical field [0001] The present invention relates to an automatic rising curtain device for dust-proof, light-shielding, heat-insulating and insect-proofing, etc., especially to a curtain device in which the rotating loading force generated by the torsion of a helical spring mounted on a winding shaft is used as the driving force for winding the curtain , It is equipped with an automatic rising roller blind device that can slow down the impact and knocking sound generated when the coil spring rolls up the curtain. Background technique [0002] Curtains are essential supplies for home life and office space. Curtains can be used not only for shading, sound insulation and dust prevention, but also for decoration and beautification of the home environment. They are widely used in homes, schools and offices. Since the current general-purpose automatic lifting curtain device is to use the rotary loading force of the helical spring to roll up the curtain, because, when the curta...
