AI Technical Summary
In existing cord reels, the base and the cord drum are not the same length, which causes the curtains to wrinkle and the cord to become tangled when they encounter obstacles.
Design a rope winder with a U-shaped base cross section. The rope drum is rotatably set in the U-shaped groove of the base. The base and the rope drum are the same length and are equipped with a cover plate to form a rope winding limiting cavity. The regular arrangement of the rope is ensured by the cooperation of the limiting rib and the annular limiting groove.
When the curtain encounters an obstacle at the bottom, the cord can still maintain a regular arrangement, avoiding tangling and improving the performance of the cord reel.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of curtain products, and more specifically, it relates to a rope reel. Background Technology
[0002] Currently used cord winders, especially driven cord winders, often have a mismatch between the base and the drum length. The base is shorter than the drum. When the curtain encounters an obstacle at the bottom during the up-and-down movement, the curtain will fold, and the cord will also be folded along with the curtain fabric. The cord on the cord winder will also be slack. Because the base is shorter than the drum, the cord on the cord winder will become tangled, disrupting the original orderly cord winding. Utility Model Content
[0003] This utility model provides a rope winder to solve the technical problems existing in this field.
[0004] This utility model provides a rope winder to solve the above-mentioned technical problems. It includes a base and a rope drum. The base has a U-shaped cross-section. The rope drum is rotatably disposed in a U-shaped groove on the base. The rope winding receiving part of the base has the same length as the rope winding part of the rope drum. A cover plate can also be detachably disposed on the base. A rope winding limiting cavity is formed between the cover plate and the rope winding part of the rope drum.
[0005] Furthermore, the base is provided with a U-shaped limiting rib, and the rope drum is provided with an annular limiting groove that matches the limiting rib. The rope drum is rotatably mounted on the limiting rib through the annular limiting groove.
[0006] Furthermore, the inside of the rope drum is provided with several axial drive grooves or drive ribs.
[0007] Furthermore, the cover plate is detachably mounted on the base via a snap-fit mechanism.
[0008] Furthermore, a rope winding hole is provided at the bottom of the side of the base where the U-shaped limiting rib is located.
[0009] This utility model relates to a cord winder, including a base and a cord drum. The base has a U-shaped cross-section, and the cord drum is rotatably mounted in a U-shaped groove on the base. The length of the cord winding portion of the base is consistent with the length of the cord winding portion of the cord drum. A cover plate can be detachably mounted on the base, forming a cord winding limiting cavity between the cover plate and the cord winding portion of the cord drum. During use, because the length of the cord winding portion of the base is consistent with the length of the cord winding portion of the cord drum, and the cover plate limits the cord winding within the limiting cavity, even if the cord becomes slack when encountering an obstacle on the bottom beam of the curtain, the cord within the limiting cavity will still be neatly arranged and will not become tangled, thus improving the performance of the cord winder.

[0014] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." The following descriptions are preferred embodiments of the present invention; however, these descriptions are intended to illustrate the general principles of the invention and are not intended to limit its scope. The scope of protection of this invention is determined by the appended claims.
[0015] The present invention will be further described in detail below with reference to the accompanying drawings. The directional terms such as "upper", "lower", "left" and "right" described in the specification are only for better understanding and explanation, and are not intended to limit the present invention.
[0016] Example 1
[0017] like Figure 1-5As shown, a rope winder includes a base 1 and a rope drum 2. The base 1 has a U-shaped cross-section. The rope drum 2 is rotatably disposed in a U-shaped groove on the base 1. The rope winding receiving part of the base 1 has the same length as the rope winding part of the rope drum 2. A cover plate 3 can also be detachably disposed on the base 1. A rope winding limiting cavity 4 is formed between the cover plate 3 and the rope winding part of the rope drum 2.
[0018] In use, the base 1 of the cord reel is fixed to the end of the upper beam of the curtain. One end of the curtain cord is fixed to the cord reel 2, and the other end of the cord of a set length is evenly wound around the cord reel 2 and housed in the cord limiting cavity 4. The other end then passes through the curtain fabric and connects to the bottom beam of the curtain. Because the length of the cord receiving part of the base 1 is consistent with the length of the cord winding part of the cord reel 2, and a cover plate 3 is provided to limit the cord winding in the cord limiting cavity 4, even if the cord becomes slack when it encounters an obstacle on the bottom beam of the curtain, the cord winding in the cord limiting cavity 4 can still be arranged regularly without becoming tangled, thus improving the performance of the cord reel.
[0019] Preferred, such as Figure 5 As shown, the base 1 is provided with a U-shaped limiting rib 1a, and the rope drum 2 is provided with an annular limiting groove 2a that matches the limiting rib 1a. The rope drum 2 is rotatably mounted on the limiting rib 1a through the annular limiting groove 2a. The U-shaped limiting rib 1a limits the movement of the rope drum 2, and the bottom of the U-shaped limiting rib 1a is arc-shaped and cooperates with the annular limiting groove 2a, making the rope drum 2 more stable and reliable when driven to rotate.
[0020] More preferably, the inside of the rope drum 2 is provided with a plurality of axial drive grooves or drive ribs 2b. The axial drive grooves or drive ribs 2b provided in the rope drum 2 are configured to limit the movement of the manual or electric winding tube, thereby winding and unwinding the rope as the manual or electric winding action is performed, thus achieving the purpose of winding and unwinding the curtains.
[0021] More preferably, the cover plate 3 is detachably mounted on the base 1 by means of a snap fastener. The snap fastener method facilitates the assembly and disassembly of the cover plate 3 and the base 1, making installation and maintenance easier.
[0022] More preferably, a rope winding hole 1b is provided at the bottom of the base 1 on one side of the U-shaped limiting rib 1a. The rope winding hole 1b is provided on one side of the U-shaped limiting rib 1a to facilitate the rope output of the rope winder and to facilitate connection and assembly with the curtain.
[0023] This utility model relates to a cord winder, including a base and a cord drum. The base has a U-shaped cross-section, and the cord drum is rotatably mounted in a U-shaped groove on the base. The length of the cord winding portion of the base is consistent with the length of the cord winding portion of the cord drum. A cover plate can be detachably mounted on the base, forming a cord winding limiting cavity between the cover plate and the cord winding portion of the cord drum. During use, because the length of the cord winding portion of the base is consistent with the length of the cord winding portion of the cord drum, and the cover plate limits the cord winding within the limiting cavity, even if the cord becomes slack when encountering an obstacle on the bottom beam of the curtain, the cord within the limiting cavity will still be neatly arranged and will not become tangled, thus improving the performance of the cord winder.
