Further, a position limiting post 333 is installed in the bottom plate 33 facing the receiving stand 31, and the position limiting post 333 is used by fitting an elastic member 334 and pushing the receiving stand 31 upward by the elastic member 334. Thus, the support roller 32 is pushed up, and the passive gear 322 and the cord winding roller unit 20 mesh with each other to form an interlocked state.
The support roller 32 is positioned between two take-up rollers 21, and the bottom plate 33 is provided with a position limiting cover plate 335 corresponding to the through hole 174 so that the pedestal 31 has an operating portion 313. Defines the distance to move downward. The handwheel 40 is installed with a cord winding space 13 in which the position limiting frame 12 is installed, which has a cover plate 41 and a rotating handle 42. Two coupling pillars 411 are installed on the inner surface of the cover plate portion 41, and are inserted into and connected to two joint holes 212 of one winding roller 21 in the two coupling pillars 411, Further, a second ring body 412 is installed on the inside of the cover plate portion 41 corresponding to the first ring body 131. The second ring body 412 has a gap so as not to contact the first ring body 131 when assembling the handwheel 40.

  As shown in FIG. 2 to FIG. 5, the cord winding device installs the cord winding roller unit 20, the meshing unit 30 and the hand driver 40 in order on the base 10 as shown in FIGS. 2 to 5. The cord take-up roller unit 20 assembles two take-up rollers 21 on the side surface having the sloped ring portion 217, and is mutually fitted by a protrusion 213 and a recess 214 formed on the end face of the joint hole 212. By positioning and further fixing by two fixing members 215, the assembly of the cord winding roller unit 20 is completed. Between the two winding rollers 21, a V-shaped ring tank 218 is formed by a bevel ring portion 217, and the cord winding roller unit 20 is formed in the central axial column 14 of the cord winding space 13 by the central hole 211. It is drilled. Also, the end of the central shaft post 14 is installed together with the position limiting plate 15, and the cord winding roller unit 20 is confined within the cord winding space 13. The support roller 32 of the meshing unit 30 straddles and installs the axial holes 311 of the standing plates on both sides of the pedestal 31 by the axial center 323. The bottom plate 33 is pivoted below the pedestal 31, and the resilient member 334 is fitted by the position limiting post 333, and is abutted against the recess 312 of the pedestal 31 and limited.

  Finally, the meshing unit 30 is incorporated into the storage tank 171 of the assembly unit 17 from the bottom up, and the pedestal 31 is incorporated into the storage tank 171 along the longitudinal tank 173 by an upright plate, and the operation The portion 313 is provided to protrude outside the through hole 174 of the assembly portion 17. Further, the bottom plate 33 is fixed to the bottom of the storage tank 171 together with the fixing member 332, and the support 31 is pushed up by the elastic member 334 and moved upward, so that the support roller 32 takes up two rolls. The roller 21 is positioned between the V-shaped ring tanks 218 in a relative manner. At the same time, the passive gear 322 and the ratchet gear 216 of the winding roller 21 mesh and interlock. Finally, the hand driver 40 is installed opposite to the cord winding space 13 of the position limiting frame 12. The second ring body 412 is positioned so as to be fitted into the cord winding space 13, and is engaged with the two joint holes 212 of the winding roller 21 by the two coupling pillars 411 of the lid plate portion 41 for positioning. Do. Further, by being limited by the lid plate portion 41 to abut on the open end, the coupling post 411 is coupled and fixed to the winding roller 21 by the screw plug 413, and the cord 40 is turned. The take-up roller unit 20 rotates. The above-described structure completes the assembly of the structure.

  The actual use of the structure is as shown in FIGS. 6-8, wherein the cord winder is secured to the wall by the base 10 and is used with the cord 50 of the curtain. The cord 50 of the curtain hangs down and is arc-shaped to connect the ends to each other, and the meshing unit 30 normally hits the cord winding roller unit 20 by pushing up the elastic member 334. When it is desired to use the cord 50 with a cord retractor, the hook 40 is first removed from the base 10 and then the actuating portion 313 protruding out of the through hole 174 is operated downward to receive the cord. The support roller 32 at the platform 31 is moved away from the cord winding roller unit 20. At this time, the cord 50 is guided from the cord discharge passage 16 into the cord winding space 13 and wound around the V-shaped ring tank 218 between the cord winding roller units 20 to be in a traction tension state and loosen the operating portion 313. And move upward by pushing up the elastic member 334. The cord 50 is meshed with the V-shaped ring tank 218 by the support roller 32, and the passive gear 322 is meshed with the ratchet gear 216 of the winding roller 21 at the same time. Finally, when the hand winder 40 is returned again, the arrangement between the cord winder and the cord is completed, the cord winder is attached to a commonly used cord type curtain, and the practicality of the structure is greatly improved. .

  As a practical example of the winding of the structure, as shown in FIGS. 3 to 5 together with FIG. 9, the cord 50 is wound into the V-shaped ring tank 218 of the cord winding roller unit 20 and the clamping restriction of the support roller 32 As the passive gear 322 of the support roller 32 is engaged between the ratchet gears 216 of the two take-up rollers 21, the cord take-up roller unit 20 can be rotated when the user causes the handwheel 40 to rotate. Is actuated by the rotation of the hand driver 40, and simultaneously rotates the support roller 32 in unison. When the two winding rollers 21 mesh the cord 50 by the meshing convex rib 219 of the slope ring portion 217 and the meshing emboss 321 of the surface of the support roller 32, the circulation operation of pulling on the cord 50 and pressing on the cord 50 And interlocking the cords 50 achieves the control operation of the curtain.

  The following effects can be obtained by the specific embodiment structure described above. Since the cord winder is additionally installed on a widely used cord-type curtain in the market, the consumer achieves the manual cord adjustment function with the simplest additional installation method. Not only is the replacement of curtains not only expensive but also the installation of the cord winder is simple and speedy, so that the consumers themselves can be installed by DIY, and the practicality of the structure is greatly improved. At the same time, consumers are encouraged to buy.

  Besides, when the curtain cord 50 is used with the cord winder, the cord 50 is straight and is restricted between the curtain head rail and the cord winder, so that the cord 50 swings and tangles by hand. It is prevented, and the small child can pull and play to prevent the occurrence of dangerous situations such as entanglement and winding around the neck, and the safety of the curtain cord use is greatly improved.

  As described above, the present invention is a prominent structural design, and the contents of the invention improve on the existing, while at the same time having industrial applicability and inventive step. Furthermore, the present invention is unseen in all the publications and has the conditions of a utility model registration application in order to be novel.

  The above is only a part of the embodiment according to the present invention, and does not limit the scope of the present invention. That is, equivalent changes and modifications based on the claims of the present invention are all included in the claims of the present invention.
