Problems solved by technology

[0005] In addition, the torsion spring cannot be completely relaxed and rotated when the curtain is unfolded or retracted, so that when the curtain is retracted, not only must the fabric and the weight of the lower rod of the roller blind be overcome, but also Overcome the friction force generated by the torsion spring and the mandrel when it rotates

Embodiment Construction

[0041] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0042] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a curtain head, also known as a curtain driver, is applied to the curtain to drive the curtain reel to rotate, thereby unfolding or retracting the curtain.

[0043] The driver includes: a base 100, a brake disc 200, a movable wedge, a bead disc 500 and a pipe plug, and it is worth noting here that the difference between it and the traditional manual bead driver is that its overall structure is more reasonable, And it is very ingenious. The brake disc 200 is locked with the base 100 to achieve the purpose of self-locking, and the self-locking is released through the ingenious connection of the movable wedge with the bead disc 500 and the br...

Abstract

The invention provides a curtain bead-pull driving device. The curtain bead-pull driving device comprises a base, a brake disc, a pipe stopper, movable wedges, and a bead disc, wherein the base is fixedly arranged, and a mandrel is arranged on the base; an umbrella-shaped oblique plane is arranged at the rear end of the brake disc, the brake disc is arranged on the mandrel in a penetrated mode, and the base limits rotating of the brake disc when the brake disc is in abut connection with the base; the pipe stopper is used for driving a curtain reel pipe to rotate, and the pipe stopper is connected with the brake disc in a linked mode; the movable wedges are movably arranged on the umbrella-shaped oblique plane of the brake disc, and located between the pipe stopper and the base; and the bead disc is arranged on the outer portion of the brake disc in a sleeving mode, and connected with the movable wedges in a linked mode, and when the bead disc rotates, the bead disc compresses the movable wedges, so that the movable wedges drive the brake disc to be separated from the base. The curtain bead-pull driving device has the beneficial effects that the bead-pull driving device can achieve the self-locking function with a torsion-spring-free structure, thus a curtain is stable when being opened or closed, moreover, large friction force cannot be generated, labor is also saved when a user pulls the curtain, and the curtain bead-pull driving device is stable and reliable when being used.

Description

technical field [0001] The invention belongs to the technical field of curtain drivers and relates to a curtain head. Background technique [0002] Curtains are arranged in places such as offices, hotels, restaurants, classrooms, and families. The curtains have bead drivers, and the curtain rollers can be rotated by the bead drivers, thereby achieving the effect of putting down or putting away the curtains. [0003] Because the pull bead driver (or called the head) of the manual pull bead curtain is simple in structure and easy to use, it is widely used. [0004] Generally, the stopping function of the manual pull bead driver is completed by one or more self-locking torsion springs on the fixed mandrel of the driver. Due to the self-weight of the roller blind fabric and the lower rod of the roller blind, the torsion spring is always in a pre-tensioned state that fully bears the weight. [0005] In addition, the torsion spring cannot fully relax and rotate when the curtain ...
