Problems solved by technology

[0003] The aforementioned rope reels are relatively useless for common-sized curtains, but if they are used with special-sized (such as narrow and long) curtains, they are likely to interfere with other components due to their length.

Embodiment Construction

[0047] The applicant first explains here that in the embodiments and drawings to be described below, the same reference numerals represent the same or similar components or structural features.

[0048] Please see first figure 1 and figure 2 , the double-deck rope reel 10 of the present invention includes a driving unit 20 , a rope winding unit 30 , and a first transmission shaft 40 .

[0049] The driving unit 20 has an upper base 21, a first coil spring gear 22, a second coil spring gear 23 and a coil spring 26, wherein:

[0050] The upper base 21 has a first top plate 211 and a first bottom plate 212 , and the first top and bottom plates 211 and 212 are connected together by a plurality of first pillars 213 . The bottom end of each first pillar 213 has a fastening portion 214. In addition, in this embodiment, the bottom surface of the first bottom plate 212 has a bottom hole 215 (such as Figure 4 shown).

[0051] The first and second coil spring gears 22 and 23 are rot...

Abstract

The invention relates to a double-layer type rope winder. The double-layer type rope winder comprises a drive unit and a rope winding unit arranged below the drive unit, wherein the drive unit is provided with an upper pedestal, two coil spring gears and a coil spring, the two coil spring gears are rotatably arranged on the upper pedestal and are mutually engaged; the coil spring is connected to the two coil spring gears; the rope winding unit is provided with a lower pedestal, two rope winding wheels and two lifting transmission ropes; the lower pedestal is connected to the upper pedestal ofthe drive unit; the two rope winding wheels can be rotatably arranged on the lower pedestal synchronously, and coaxially correspond to the coil spring gears of the drive unit; and the two lifting transmission ropes are separately connected to the two rope winding wheels. Besides, the two coil spring gears and the two rope winding wheels in correspondence up and down are separately connected through transmission shafts, so that the two coil spring gears and the two rope winding wheels can synchronously rotate. The double-layer type rope winder can achieve the mini effect by shortening integrallength.

Description

technical field [0001] The invention relates to curtains, in particular to a double-layer rope reel used for curtains with no exposed drawstrings. Background technique [0002] Generally speaking, the curtains without exposed drawstring mainly use the rope reel installed in the upper beam to retract the lifting transmission rope. During the process, it will gradually rise relative to the upper beam, so that the blades will be stacked together by the upward movement of the lower beam, so as to achieve the purpose of folding the curtain. [0003] The aforementioned cord reels are not problematic for common-sized curtains, but if they are used with special-sized (such as narrow and long) curtains, they are likely to interfere with other components due to their length. Therefore, how to appropriately shorten the length of the aforementioned rope reel without affecting its transmission effect is an urgent problem to be solved in the industry.
