Press-button type multi-stage winding mechanism

Abstract

A press-button type multi-stage winding mechanism is disclosed. The winding mechanism comprises a top and bottom cover, a button, a looped spring, a sliding disc, wire, a winding disc, and bottom disc. The wire is pulled to a required length and will be automatically positioned. The distance of the wire is precisely controlled and the button is pressed to secure, and to release by pressing again the button which can rapidly wind the wire.

1 . A press-button type multi-stage winding mechanism comprising a top cover, a button, a spiral spring, a sliding disc, traction line, a winding disc, a bottom disc, a bottom cover, wherein 
 the top cover has a block plate at the inner edge of the external side of the cover to secure the spring so as to pivotally mount to the button at the top cover,    the button is pivotally mounted at the inner edge of the top cover and the front of the button is extended to form an urging rod which is corresponding to the positioning block provided at the external edge of the sliding disc;    the spiral spring is positioned at the edge seat of the sliding disc and has an inner end fastened to the center shaft of the bottom disc, and has an external end mounted to the inner wall of a clip plate of the edge seat so that the spiral spring is restricted by the center shaft and the sliding disc;    the sliding disc is fastened to the winding disc and the top portion of the edge seat is for the urging of the spring, and the center shaft of the bottom disc is a through hole for the engagement with the inner edge of the spiral spring, and the external edge of the edge seat is one or at least one positioning block which is corresponding to the urging rod of the button;    the wire passes through the through hole of the winding disc and is led to the reverse direction edge seat so that the boundary of the wire is divided into a positive wire and a reverse direction wire which are respectively mounted onto the positive direction and reverse direction of the edge seat, and the positive and reverse direction wire of the boundary point are secured by a securing plate at the edge seat, and the reverse direction wire passes through the sot of the center shaft and is secured at the bottom slot so that the end of the reverse direction is a specific end head of the wire;    the winding disc has a positive direction edge seat face and a negative edge seat face, wherein the positive edge seat has an engaging button to engage with an engaging hole of the sliding disc, and the positive direction wire surrounds the external edge of the positive direction winding seat and passes through the through hole of the winding seat to the negative direction edge seat and winds at the engaging, plate on the negative edge seat for positioning;    the bottom disc has a center shaft having a bottom slot allowing the negative direction wire end to pass through and is positioned at the engaging slot of the bottom disc so that an end head is formed at the wire; and    the bottom center which is corresponding to the top cover to form a sealing and thus a winding mechanism is formed.    
   
   
       2 . The winding mechanism of  claim 1 , wherein the wire is wiring which is divided into a positive direction wire and a negative direction wire.  
   
   
       3 . The winding mechanism of  claim 1 , wherein the positive direction wire end is a connection conductive end or transmission connection end, and the negative direction wire end is connected to a connecting object.
