Two-way winder

Technical field

The utility model relates to the bidirectional signal line wrap-up, particularly relates to a kind of two-way automatic winding holding wire function that possesses, to adjust the two-way winder that holding wire uses length.

Background technology

All kinds of sources of sound, signal of video signal line, or the signal transmssion line of the peripheral product of all kinds of calculators, such as USB specification transmission line etc., after its two ends were provided with plug, total length will immobilize.General user is when selecting holding wire, and the necessary operations length of can evaluating oneself is earlier mostly selected the holding wire of a total length greater than maximum working length again.Yet, twine easily when the long holding wire of length uses and is entangled with, cause user's inconvenience, and in disorder holding wire also tangles knotting easily and influences useful life during collection.Therefore most of people can utilize band to be brought holding wire together binding, and the length with needs discharges in use.

Because it is too numerous and diverse to use band to bundle the process of bringing holding wire together, therefore just there is the mechanism of unidirectional automatic winding holding wire to be suggested, the rolling-up mechanism of this class includes the rotating disk that utilizes wind spring to turn, and with the elastic torque that wind spring produces, promotes rotating disk and rotates the rolling holding wire automatically.Because in holding wire is stretched process, rotating disk just constantly rotates and makes wind spring produce reverse elastic torque, therefore the mechanism of automatic winding holding wire also includes a backstop brake device, make it not to be subjected to wind spring to drive the rolling holding wire to fix this rotating disk, the tensile elongation of framing signal line is utilized for the user.If the unidirectional technology of this kind then is found in TaiWan, China patent TW444174 when being applied to small-sized calculator peripheral unit, or in the case such as U.S. US6088021; Yet the mode of this kind simple tension (is the variable-length of winder one end, the other end of winder is then constant with the fixed distance of circuit board), when take-up, usually has bigger rolling power, therefore the very easy holding wire that causes comes off from the contact of circuit board, or the disappearance of the fracture of the wire rod in the holding wire.

For overcoming above-mentioned disappearance, for example TaiWan, China patent TW529819 patent case or Chinese patent CN2510920 patent case, a rotating disk is pivoted between two housings, utilize a wind spring to form an elastic torque with respect to housing, consistently rotating disk is imposed a rolling power, the automatic winding holding wire so as to driving dial rotation is offered a stopper slot in one of this two housing simultaneously, offers corresponding groove, oblique guide groove and arcuation short slot etc. at the end face of rotating disk.Shift one's position between guide groove and guide groove by ball, in stopper slot, do corresponding change in location simultaneously, can make the effect of ball, to adjust the tensile elongation of holding wire rotating disk generation backstop or clip.In addition, among TaiWan, China patent TWM260039 a case, though change above-mentioned ball the swing arm of an activity into, and omitted the use of stopper slot, but still must cooperate the oblique guide groove set on the rotating disk and the design of arcuation short slot, just can reach the effect of location.

Yet, guide groove, groove and arcuation short slot among the above-mentioned three patent cases, its making, course of processing complexity, its design process also must be through complicated calculating, angle of the degree of depth of the length of groove and guide groove, arc groove and relative position, arc groove and groove, guide groove etc. for example, all must be through complicated calculations, the beginning can play a role, the degree of difficulty when increasing design.And its semi-finished product need with housing ball or swing arm to be folded in the groove of rotating disk end face when assembling, and assembling process is comparatively complicated, slow.On actual the use, in the stretch signal line process, move if stop to stretch, rotating disk still can be done reverse and rolling segment signal line by a small margin, the location ball could arrive the location, producing backstop brake effect stops operating rotating disk, the holding wire length of this reverse rolling is difficult for grasping, and therefore also is difficult to accurately adjust the tensile elongation of holding wire.Moreover, after long-term the use, no matter be between ball or swing arm and each guide groove, also be easy to generate loss, cause the disappearance that is difficult for the location.The complex structure of the holding wire wrap-up of prior art, and backstop brake accuracy deficiency can't be adjusted holding wire effectively and be stretched in the length of rolling-up mechanism outside.
