Problems solved by technology

[0007] The above-mentioned clutch device of a curtain driver essentially discloses a curtain driver, which realizes the rolling of the curtain through the clutch device, but essentially still cannot solve the problem that the torsion spring is always fully bearing the weight of the roller blind fabric and the lower rod. Preloaded state, so it is more difficult to use

Embodiment Construction

[0033] 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.

[0034] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a pull-bead driver is applied to a curtain, and in actual use, it can drive the curtain reel to rotate, thereby unfolding or retracting the curtain.

[0035] The driver includes a pipe plug 100, a ratchet 210 clutch mechanism, a base 300, and a bead plate 400, 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 uses a ratchet The 210 clutch mechanism replaces the torsion spring and the shaft, so that it can overcome the self-weight of the roller blind fabric and the lower rod of the roller blind so that the torsion spring is always in a p...

Abstract

The invention provides a bead pull type driver. The bead pull type driver comprises a pipe plug, a ratchet clutch mechanism, a base and a bead disc, wherein the pipe plug is in socket connection with a curtain reel pipe and can drive the curtain reel pipe to rotate; the ratchet clutch mechanism is connected with the pipe plug and is used for locking the pipe plug; the base is fixedly arranged; the base is connected with the ratchet clutch mechanism and restricts the ratchet clutch mechanism from rotating; the bead disc is connected with the pipe plug; and when the bead disc rotates, the ratchet clutch mechanism is separated from the base and drives the pipe plug to rotate. The bead pull type driver has the beneficial effects that torsional spring self locking is not required, braking is reliable, and utilization is relatively effort-saving.

Description

technical field [0001] The invention belongs to the technical field of curtain drivers and relates to a pull-bead driver. 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 bead driver (or called head) of the 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 is unfolded or re...
