Blind cord winder fixing structure

Abstract

A blind cord winder fixing structure including a fixing body, a shaft gear, a cord winder, a movable cover and a locating cover board having a central stem. The fixing body is composed of a first case body and a second case body mated with each other. Inner faces of the first and second case bodies are formed with complementary arced recesses, which together form a passage. A shaft rod is rotatably received in the passage. The shaft rod has a worm section engaged with the shaft gear. Lower sides of the first and second case bodies are respectively formed with projecting shafts fitted in a sleeve of the movable cover, which supports the cord winder. The stem of the locating cover board is received in a circular hole of the fixing body. The locating cover board is horizontally rotatable, whereby two arced bracket sections of two ends of the locating cover board can be moved into a blind rail rack and engaged therewith to fixedly locate the fixing body in the blind rail rack.

1 . A blind cord winder fixing structure comprising:
 a fixing body including a first case body and a second case body corresponding to the first case body in configuration, inner faces of the first and second case bodies being respectively formed with several fixing holes, whereby threaded rods can be screwed through the fixing holes to fixedly assemble the first and second case bodies with each other, upper walls of the first and second case bodies being respectively formed with semicircular notches, which are complementary to each other, whereby when the first and second case bodies are assembled with each other, the semicircular notches together form a circular hole;   a locating cover board having a stem downward extending from the locating cover board, the stem being fitted through the circular hole of the defined by the first and second case bodies, whereby the locating cover board is horizontally rotatable, two ends of the locating cover board being respectively formed with arced bracket sections, upper sides of the aced bracket sections being respectively formed with platforms;   a shaft gear received in and positioned between two shaft holes formed on inner faces of the first and second case bodies, the shaft gear having multiple gear teeth;   a cord winder including a shaft rod having a worm section and a cord reel having two disc sections on two sides, the shaft rod extending from one of the disc sections, the worm section of the shaft rod being engaged with the gear teeth of the shaft gear; and   a movable cover having a sleeve and a support board horizontally extending from a lower end of the sleeve, the sleeve having a shaft hole, lower sides of the first and second case bodies being respectively formed with projecting shafts, the projecting shafts being fitted in the shaft hole of the sleeve, the stem of the locating cover board being received in the circular hole of the fixing body to prevent the locating cover board from detaching from the fixing body, the locating cover board being horizontally rotatable to fixedly engage and locate the fixing body in a blind rail rack.   
   
   
       2 . The blind cord winder fixing structure as claimed in  claim 1 , wherein a stopper section with larger diameter is formed at a bottom end of the stem of the locating cover board.
