Positive pulling force slider of zipper fastener
Technical field
The present invention is relevant with slide fastener, specifically refers to a kind of positive pulling force slider of zipper fastener.
Background technology
nullThe slide fastener comprising slider of zipper fastener has a wide range of applications in daily life,Slider of zipper fastener is typically by pulling-on piece、Draw nose、Zipper lock three part forms,Nose is drawn to be fixed on the end face of zipper lock by former and later two end points,Pulling-on piece then by its lower end with draw the connecting hole on nose to wear even to be flexibly connected,Owing to the folding of slide fastener is to drawing nose force to allow zipper lock overcome the resistance of zipper teeth on slide fastener just to realize by the pulling-on piece on slider of zipper fastener,Can be seen that the drag direction of the tractive force direction of pulling-on piece and zipper lock slide fastener between cog is not on the same line from above-mentioned design feature,There is certain deviation in the i.e. direction of power,The direction of draw of pulling-on piece cannot form, lower, the positive pulling force that direction is unified in upper drag direction、Resistance combines,Simultaneously,Pulling-on piece with draw nose combination only one of which point can not apply traction force when deliberately adjust traction force direction to balance above-mentioned deviation,Add the abrasion during use、Deformation etc. more can increase the weight of this deviation,Thus make what slider of zipper fastener made to become when folding tractive moves on slide fastener to have some setbacks,The involved and abstruse retardance of operation of slide fastener;Rock in the state that friction produces the sound it addition, pulling-on piece and the combination drawing nose are in the most all the time, so, this slider of zipper fastener extensively seen needs to improve to facilitate and be beneficial to use.
Summary of the invention
The purpose of the present invention is to provide the new technical scheme positive pulling force slider of zipper fastener of a kind of slider of zipper fastener, and it can solve aforesaid problem.
The content of technical solution of the present invention is as follows: it comprises pulling-on piece, draws nose, zipper lock, described in draw nose be the semicirque containing interstitial hole, just going up and drawing backward is machined with the semicircle upper latch notch of gap shape, rear bayonet socket respectively on the arcuation disc of nose at interstitial hole;The lower half of described pulling-on piece is truncated into rectangular box-like, the lower frame of rectangle frame is cylindrical pulling-on piece axle, on the face that the frame limit, left and right of this rectangle frame is relative, symmetry is machined with one section of relative chute of notch, the shaft of one circle i.e. slide bar is horizontally placed between the chute of left and right, connection nervous between the upper ledge limit of slide bar and rectangle frame has a flexuose steel wire compression spring, pulling-on piece is penetrated in the interstitial hole drawn on nose by pulling-on piece axle and is flexibly connected, and slide bar is then pressed on and draws on the upper latch notch on nose disc or rear bayonet socket.
The invention has the beneficial effects as follows: pulling-on piece can correct the deviation in direction between traction force and resistance because the combination of two points of its pulling-on piece axle and slide bar contacts when by drawing nose tractive zipper lock folding slide fastener effectively, the folding making slide fastener is the most smooth and easy light, is the useful improvement of this apparatus of slide fastener.
Accompanying drawing illustrates:
Fig. 1 is the front view of the design slider of zipper fastener.
Fig. 2 is right side view and pulling-on piece folding schematic diagram.
Fig. 3 is zipper lock and the front view drawing nose and right flank view.
Fig. 4 is the amplification front elevation of pulling-on piece.
In each figure, 1 is pulling-on piece, and 2 is stage clip, and 3 is chute, and 4 is slide bar, and 5 for drawing nose, and 6 is pulling-on piece axle, and 7 is zipper lock, and 8 is upper latch notch, and 9 is rear bayonet socket, and 10 is interstitial hole.
Detailed description of the invention:
Explanation for example to the design below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the slider of zipper fastener of the design comprises pulling-on piece 1, draws nose 5, zipper lock 7, it is described that to draw nose 5 be a kind of semicirque containing interstitial hole 10, interstitial hole 10 just go up and drawing backward is machined with the semicircle upper latch notch 8 of gap shape, rear bayonet socket 9 respectively on the arcuation disc of nose;The lower half of pulling-on piece 1 is processed as rectangular box-like, the lower frame of rectangle frame is cylindrical pulling-on piece axle 6, on the face that the frame limit, left and right of this rectangle frame is relative, symmetry is machined with one section of relative chute of notch 3, the shaft of one circle i.e. slide bar 4 is horizontally placed between the chute of left and right, connection nervous between the upper ledge limit of slide bar 4 and rectangle frame has one by the flexuose stage clip 2 of spring steel wire nest system, pulling-on piece 1 is penetrated in the interstitial hole 10 drawn on nose 5 by pulling-on piece axle 6 and is flexibly connected, and slide bar 4 is then pressed on and draws on the upper latch notch 8 on nose disc or rear bayonet socket 9.nullTime specifically used,The vertical type i.e. slide bar that manipulated by pulling-on piece 1 such as Fig. 2 shape is absorbed in the state in upper latch notch 8,So pulling-on piece and combination drawing nose is exactly the combination of two points comprising pulling-on piece axle and slide bar,Pulling-on piece is handled the ability of zipper lock 7 and is improved and strengthens,Change the deficiency that it cannot effectively be manipulated by the combination only one of which point of common zipper head pulling sheet and zipper lock,So,Pulling-on piece just can come the direction adjusting traction force deliberately to balance aforesaid traction force and resistance deviation on direction by the combination of this reinforcement applying traction force when,The folding making slide fastener is the most smooth and easy light,Additionally,Make again after pulling-on piece tractive puts in place its by vertical type be returned to horizontal i.e. allow slide bar be absorbed in again after in state in bayonet socket 9,So pulling-on piece will combine closely with drawing nose,Will not rock again and not stop also will not produce sound,During this regulation, slide bar can be along drawing the cambered surface of nose to slide,What slide bar also synchronized slides up and down in chute,This regulation process of the cooperation that stage clip and chute can be coordinated.
