Example Embodiment

[0033] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, 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 drive is applied to curtains. In actual use, the curtain reel can be driven to rotate to expand or close the curtain.

[0035] The driver includes a pipe plug 100, a ratchet 210 clutch mechanism, a base 300, and a bead plate 400. It is worth noting here that the difference from the traditional manual bead driver is that its overall structure is more reasonable and a ratchet is used. The 210 clutch mechanism replaces the torsion spring and the shaft, which can overcome the dead weight of the roller blind fabric and the lower rod of the roller blind so that the torsion spring is always in a pre-tensioned state that fully bears the weight.

Abstract

The invention provides a ball-pulling driver, comprising: a pipe plug, which is used for being inserted into a curtain roll and can drive the curtain roll to rotate; a ratchet clutch mechanism, which is linked with the pipe plug and used for locking The pipe plug; a base, which is fixedly arranged, the base is connected with the ratchet clutch mechanism to limit the rotation of the ratchet clutch mechanism; a bead plate, which is linked and connected with the pipe plug, and the bead plate rotates The ratchet clutch mechanism is separated from the base to drive the pipe plug to rotate; the beneficial effects of the present invention are: no torsion spring self-locking, reliable braking, and relatively labor-saving use.

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...
