Description

Rope divider for curtain rope reels

technical field

The present invention relates to curtains, in particular to a cord separating piece for curtain cord reels.

Background technique

As far as the common curtain is concerned, the expansion and contraction of the blades are mainly driven by a plurality of transmission ropes. Taking the retraction of the blade as an example, when the rope reel is driven by the power source and starts to rotate, the transmission rope will be reeled by the rope reel fixed by itself, and then the transmission rope will be further pulled during the reeling process. The lower beam is pushed by the lower beam and the blades are stacked together from bottom to top in order, so that the folding of the blades is completed.

However, in the above-mentioned prior art, the transmission ropes are prone to interfere with each other or become entangled and knotted during the transmission process, which may not only cause the blades to operate unsmoothly, but may even cause the blades to get stuck and cannot be retracted. Happening.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to provide a rope divider for a curtain rope reel, which can avoid the situation that the two transmission ropes interfere with each other or become entangled and knotted during the transmission process.

In order to achieve the above-mentioned purpose, the rope separating piece of the present invention includes a supporting portion, two wing portions and two extending portions. The two wing parts extend from two opposite sides of the support part in a direction away from the support part, and the two wing parts respectively have a rope threading hole, and each rope threading hole is used for a transmission rope to pass through; The extension parts extend oppositely from a side surface of the wing part along a direction parallel to the axial direction of the rope passing hole, and each extension part has a positioning end, and the positioning end is used for the rope separation piece of the present invention to follow Assembly and positioning of the curtain rope reel. Therefore, the rope separating sheet of the present invention can separate the two transmission ropes, so as to avoid the situation that the two transmission ropes interfere with each other or become entangled and knotted during the transmission process.

Preferably, the support part is elongated, the two wings are rotationally symmetrical with respect to the length direction of the support part, and the rope holes of the two wings are not at the same height to match the positions of the two transmission ropes.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

Please refer to FIG. 1 first, the curtain rope reel 10 shown in the figure is of the prior art, mainly used to control the retraction and retraction of the curtain blades. In terms of structure, it includes a base 20, two driving gears 24, and a coil spring 25. Two rope winding gears 26, and four paired transmission ropes 27, wherein: two opposite ends of the base 20 respectively have two side posts 21 arranged side by side at intervals and a The end opening 22, in addition, the base 20 has a convex point 23 above and below the end opening 22 respectively; two driving gears 24 are rotatably arranged on the base 20 and mesh with each other; the coil spring 25 is connected Between the two driving gears 24 , the coil spring 25 can be pulled out from the helical coiled state by the rotation of the two driving gears 24 ; the two rope winding gears 26 are rotatably arranged on the base 20 And a driving gear 24 is meshed respectively, so that the two rope winding gears 26 can be driven by the driving gear 24 meshed by themselves to rotate together; each pair of transmission ropes 27 is arranged in a winding rope in the form of upper and lower layers. The gear 26 enables each pair of transmission ropes 27 to be co-wound on the rope winding gear 26 or released from the rope winding gear 26 through the rotation of the rope winding gear 26 .

Please refer to FIG. 2 again, the rope dividing piece 30 of the present invention includes a support portion 31 , two wing portions 33 , and two extension portions 35 , wherein: the support portion 31 is elongated, and the cross-sectional shape of the support portion 31 is It is arc-shaped; the two wings 33 extend from the two opposite long sides of the support part 31 to the direction away from the support part 31 and have a rope hole 34 respectively. The rotation is symmetrical, so that the rope holes 34 of the two wings 33 are not at the same height, so that the two transmission ropes 27 can be passed through a rope hole 34 respectively according to the position of the two transmission ropes 27; The inner side surfaces of the wings 33 are oppositely extended along the direction parallel to the axial direction of the threading hole 34 and respectively have a positioning end 36 .

When used in conjunction with the above-mentioned curtain rope reel 10 , the rope separating pieces 30 of the present invention are mainly provided at two opposite ends of the base 20 in accordance with the position of the rope winding gear 26 . During assembly, as shown in FIG. 3 , firstly, the two opposite extending portions 35 are embedded in the end opening 22 of the base 20 , and the concave arc-shaped surfaces 32 of the supporting portion 31 abut against the two ends of the base 20 . The upper and lower bumps 23 are used to achieve positioning, and finally, the positioning ends 36 of the extension portion 35 are hooked to the two side columns 21 of the base 20 to complete the assembly and fixation. After the assembly is completed, as shown in FIG. 1 , the rope separating sheet 30 of the present invention can separate the two transmission ropes 27 to avoid the situation that the two transmission ropes 27 interfere with each other or become entangled and knotted during the transmission process. , in order to achieve the effect of increasing the smoothness and stability of the movement.

The specific embodiments described above further describe the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above-mentioned specific embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention. Within the spirit and principle of the present invention, any modifications, equivalent replacements, improvements, etc. made should be included within the protection scope of the present invention.
