Embodiment Construction

[0030] 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.

[0031] Please see first figure 1 and figure 2 , The three-wheel rope reel 10 of the present invention includes a base 20 , a driving unit 30 , and a rope winding unit 40 .

[0032] The base 20 is rectangular and has a top plate 21 and a bottom plate 22 . There are five pairs of upper pillars 212 on the periphery of the top plate 21, and five pairs of lower pillars 221 on the periphery of the bottom plate 22. , After the bottom plates 21 and 22 are assembled, if image 3 As shown, the right end of the base 20 has a first opening 23 , and the left end of the base 20 has a second opening 24 . In addition, the bottom surface of the top plate 21 has three upper axles 214, and the top surface of the bottom plate 22 has three lower axles 223. After the top and bottom plates 21, 22 are a...

Abstract

The invention relates to a three-wheel type rope reel, which includes a drive unit and a rope reel unit, the drive unit has two coil spring wheels meshing with each other and a coil spring connected to the two coil spring wheels, and the rope reel unit It has a coiled rope wheel and two lifting transmission ropes. The rope coiled wheel is engaged with one of the coiled spring wheels, so that the rope coiled wheel can rotate synchronously with the two coiled spring wheels. In addition, the rope coiled wheel has a rotating shaft, and the rotating shaft has an upper shaft part, the lower shaft part and a partition connecting the upper and lower shaft parts, the two lifting transmission ropes are respectively arranged on the upper and lower shaft parts of the rotating shaft, so that the two lifting transmission ropes can be wound up on the The upper and lower shaft portions of the rotating shaft are or are released from the upper and lower shaft portions of the rotating shaft. Thereby, the three-wheel type rope reel of the present invention can achieve the effect of simplifying the structure without affecting the transmission effect.

Description

technical field [0001] The present invention is related to the non-exposed drawstring type curtain, in particular to a three-wheel type cord reel used for the non-exposed drawstring type curtain. 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 simplify the structure of the aforementioned rope reel without affecting its transmission effect is an urgent problem to be solved ...
