Abstract
The utility model discloses a pull piece capable of crossing a zipper puller lock hole and aims at providing the pull piece which is capable of crossing the zipper puller lock hole and smoothly conducting tooth engaging whether the pull piece is on a single-layer zipper or a double-layer zipper or a zipper with or without a lock hole structure. The pull piece capable of crossing the zipper puller lock hole comprises a pull piece body with a thin piece, a through hole is formed at the front end of the pull piece, and the pull piece can be sleeved on a trunk bridge of a zipper puller through the through hole. The pull piece capable of crossing the zipper puller lock hole is characterized in that the length of the through hole is larger than the distance from the inner side of the joint of the trunk bridge and a zipper puller protective plate to the outer edge of a lock hole structure. Due to the fact that the through hole crosses the lock hole structure on the zipper puller, namely, the through hole covers the whole lock hole structure, an included angle between the pull piece and the moving direction of the zipper puller is greatly reduced, component force and turning torque in a pulling process is reduced, pulling is more labor-saving, friction between the zipper puller and a zipper belt is reduced, the service life of the zipper puller and the service life of the zipper belt are prolonged, the phenomenon of tooth burst is avoided, and the pull piece capable of crossing the zipper puller lock hole can be used universally in a zipper head with or without the lock hole structure.
Description
Technical field
The utility model relates to slide fastener, more specifically to a kind of pulling-on piece of crossing over lockhole on the slider of zipper fastener.
Background technology
The slider of zipper fastener that traditional case and bag are used is divided into the pull head that lockhole is arranged and the pull head that does not have lockhole substantially.Have the slider of zipper fastener of lockhole to be mainly used in soft case and bag (case and bag of woven type fabric), it utilizes left and right side respectively to wear one can to allow the padlock element wear the design of extension with lockhole and corresponding interfix.Another is the pull head of no lockhole, and its mode of locking is to be set in case and bag side lockset with the lockhole of pulling-on piece tail end with being pressed into, and dead bolt passes lockhole and pins, padlock be designed for hard case and bag.The used pulling-on piece of pull head that the pull head of lockhole is arranged under normal conditions and do not have a lockhole is general in manufacturing enterprise, namely will be assemblied on the pull head of lockhole and no lockhole with a kind of pulling-on piece.But it is unsatisfactory for the pulling-on piece that is used on the lockhole pull head.This common pulling-on piece is when on the pull head that is assemblied in lockhole, can not cross over engagement mechanism as shown in Figure 1, cause pull head to exert oneself F when moving, pulling-on piece conflict engagement mechanism is given pull head one turning torque M, brings toward the power that presses down, and the friction chain belt, cause resistance to make and draw sliding having some setbacks, especially turning, if spur the disappearance that has quick-fried tooth fast.This phenomenon still can be accepted at the conventional monolayers chain belt, but when being used for double-deck chain belt, more stiffening because of chain belt, owe soft, when pull head one end when pressing down, show more bad drawing, slide fastener close tooth the time cause about, accurately making of sprocket position, the left and right sides can not steadily close tooth, usually causes one side can close the disappearance that tooth, another side are sudden and violent tooth, draws sliding unusual especially easily at the bent face place, and can block or increase resistance in the case and bag corner, hard draw also can quick-fried tooth.
The utility model content
Folding was light when the purpose of this utility model provided a kind of use, no matter be at individual layer or double-deck slide fastener, still had or not engagement mechanism all can close the pulling-on piece of lockhole on the slider of zipper fastener crossed over of tooth smoothly.
In order to reach above-mentioned requirements, the technical solution of the utility model is: it comprises lamellated pulling-on piece, the front end of pulling-on piece is shaped on for being enclosed within through hole in the slider of zipper fastener trunk beam, it is characterized in that described through hole length is greater than the inboard of trunk beam and the pull head backplate junction distance to the engagement mechanism outer rim.
Be shaped on the lockhole that the dead bolt for case and bag slide fastener side lockset passes at the afterbody of described pulling-on piece.
Described through hole be shaped as 8 fonts or ellipse or C shape or D shape.
Pulling-on piece according to lockhole on the slider of zipper fastener crossed over of technique scheme design, through hole has been crossed over the engagement mechanism on the slider of zipper fastener, be that through hole has entangled whole engagement mechanism, make the angle of pulling-on piece and slider of zipper fastener moving direction reduce greatly, component and turning torque when having reduced pulling make pulling more laborsaving, also reduced the frictional force of slider of zipper fastener and chain belt, improved the service life of slider of zipper fastener and chain belt, avoided the generation of quick-fried tooth phenomenon, no matter in that have or not on the pull head of engagement mechanism all can be general.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and by embodiment.
Fig. 2, Fig. 3 are that the pulling-on piece of lockhole on the leap slider of zipper fastener is installed in the schematic diagram on the engagement mechanism slider of zipper fastener.As seen from the figure, it comprises lamellated pulling-on piece 1, and the front end of pulling-on piece 1 is shaped on for being enclosed within the through hole in the trunk beam 34 on the slider of zipper fastener 2, described through hole 4 length A greater than the inboard of trunk beam 3 and pull head backplate 5 junctions to engagement mechanism 6 outer rims apart from B.Be shaped on the lockhole 8 that the dead bolt 7 for case and bag slide fastener side lockset passes at the afterbody of described pulling-on piece 1.As described in Figure 4.Described through hole 4 be shaped as 8 fonts, as shown in Figure 5, or oval, as shown in Figure 6, or C shape, as shown in Figure 7, or D shape such as Fig. 8, shown in Figure 9.
