The receiving seat 31 is standing. Grouped along the longitudinal groove 173 into the receiving groove 171, and the trigger portion 313 is protruded outside the through hole 174 of the combination portion 17, and the bottom plate 33 and the locking member 332 are fixed to the bottom of the receiving groove 171, so that The receiving seat 31 is pushed upward by the elastic member 334 and is displaced upward, so that the abutment wheel 32 is relatively located between the V-shaped ring grooves 218 of the two rollers 21, At the same time, the passive gear 322 and a detent gear 216 of the reel 21 mesh with each other to form a linkage, and finally the hand crank 40 is relatively installed in the rope space 13 of the limit frame 12, and the second ring The body 412 is embedded in the rope space 13 in position, and is positioned by combining the two holes 212 of the cover portion 41 and the two holes 21 of the reel 21 with the cover portion 41 against the open end. The coupling column 411 can be further locked with bolts 413 and fixed with the reel 21, and can be driven to rotate by the reel wheel set 20 through the rotation of the hand crank 40. With the above structure, the structure can be completed. Composition.

The actual use of the structure is shown in Figures 6, 7, and 8. The rope reel is fixed on the wall through the base 10, and then used with the curtain rope 50, and the curtain rope The 50 series is vertical and forms an arc of contact at the end. Since the engaging group 30 is normally pushed by the elastic member 334 and abuts against the rope reel group 20, it is intended to match the rope 50 with the rope reel. In use, the hand crank 40 is first removed from the base 10, and then the trigger portion 313 protruding outside the through hole 174 is pulled down, so that the receiving seat 31 is lowered and the abutment The wheel 32 is far away from the rope winding wheel group 20, and at this time, the pulling rope 50 can be introduced into the rope winding space 13 from the rope exit channel 16, and then looped around the V-shaped groove 218 between the rope winding wheel group 20 and formed. In the tensioned state, when the trigger portion 313 is released, it can be pushed upward by the elastic member 334 and then displaced upward, and then the pull rope meshing is clamped between the V-shaped ring grooves 218 through the abutment wheel 32. The gear 322 is also engaged with a deceleration gear 216 of the reel 21 at the same time, and finally the hand crank 40 is installed back to complete the configuration between the rope reel and the pull rope, so that the rope reel can be additionally plus Widely used in the market of cordless blind, greatly enhance the practicality of the structure.

The structure is actually rolled up. Please refer to Figures 3, 4, and 5 and Figure 9. Because the rope 50 is wound in the V-shaped groove 218 of the rope wheel set 20, and is subject to The clamping of the abutment wheel 32 is restricted, and the passive gear 322 of the abutment wheel 32 is more engaged between the two detent gears 216 of the reel 21. When the user is rotated by the hand crank 40, the reel wheel Group 20 will follow the hand crank 40 rotates and rotates, and simultaneously drives the abutment wheel 32 to rotate, and further uses the engagement ribs 219 of the two reels 21 on the bevel ring 217 and the engagement embossing 321 on the surface of the abutment wheel 32 to actuate the drawstring 50 , Forming a loop action of pulling the rope 50 down and pushing it up, so as to control the operation of the rope 50 to reach the curtain.

By virtue of the structure of the above specific embodiments, the following benefits can be obtained: the rope reel can be additionally installed in the market-used drawstring curtains, so that consumers can achieve manual rotation through the simplest installation method The function of adjusting the rope can not only avoid the replacement of curtains and increase shopping costs, but also the installation operation of the rope reel is easy and fast. It is also convenient for consumers to DIY, which greatly improves the practicality of the structure and increases consumers. Those who want to buy.

In addition, when the curtain rope 50 is used with a rope reel, the rope 50 俾 will be linearly restricted between the curtain rail and the rope reel, and the rope 50 can prevent the rope 50 from swinging unnecessarily to entangle and knot. It can prevent infants, young children, and children from pulling and playing and causing dangerous situations such as stumbling and necking, which greatly improves the safety of the use of drawstring curtains.

In summary, this creation has indeed achieved a breakthrough structural design, with improved creative content, and at the same time, it can achieve industrial applicability and progress. This creation has not been seen in any journals, and it is also novel. In accordance with the relevant provisions of the Patent Law, I submitted an application for a creation patent in accordance with the law.

The above is only one of the preferred embodiments of this creation. When it cannot be used to limit the scope of implementation of this creation; that is, all equal changes and modifications made according to the scope of the patent application for this creation shall still belong to this creation. Within the scope of the patent.
