Detailed description of the invention
Below with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.
In following description of the present invention, front side refers to the tooth head side at chain tooth engaging piece place, and rear side refers to the tooth tail side for clamping strap; When width refers to that chain tooth is installed on strap, the direction at strap length direction place; When above-below direction refers to that chain tooth is installed on strap, perpendicular to the direction of strap.
As shown in Figure 1 to Figure 3, a kind of Elastic Meshing slide fastener, comprise on the opposite lateral margin of a pair strap 1, two strap 1 and be fixed with multiple chain tooth 2 equally spacedly, chain tooth 2 can be cold extrusion shaped metal tooth, also can be the resin chain tooth of injection mo(u)lding.The front portion of described chain tooth 2 is provided with engaging piece, what the chain tooth 2 at engaging piece rear was provided with fixing strap 1 grips groove 21, strap 1 is provided with longitudinal cloth muscle 11 of several projections on the edge part of fixing chain tooth 2, cloth muscle 11 can strengthen strap 1, simultaneously as the tread plate fixed with chain tooth.Be provided with the locating slot 211 suitable with cloth muscle 11 cross section gripping on groove 21 of described chain tooth 2, with making the face that the grips indention of chain tooth 2 with strap 1 tabling, chain tooth 2 is more firm with the combination of strap 1, and it is powerful that slide fastener has larger horizontal drawing.Upper surface and the lower surface of described chain tooth 2 are provided with technique for fixing hole 22, and described technique for fixing hole 22 is with to grip groove 21 through, and by determining fabrication hole 22, when chain tooth 2 is fixed on strap 1, the combination of chain tooth 2 and strap 1 is more firm.
As shown in Figure 1 to Figure 3, chain tooth 2 front portion is provided with the step of width constriction on the two sides of width, two steps form stage portion 23, the outer surface of stage portion 23 is arc cylinder, upper surface and the lower surface of arc cylinder and chain tooth 2 connect, two parallel step surfaces arrange described engaging piece, engaging piece comprises Elastic Teeth 3 and location indentations 24, on the two sides of chain tooth 2 width, Elastic Teeth 3 and location indentations 24 are set respectively symmetrically, Elastic Teeth 3 is near the front end of chain tooth 2, Elastic Teeth 3 is from tooth root to crown constriction gradually, Elastic Teeth 3 flexible member passing through to arrange in chain tooth 2 can stretch on chain tooth 2 width.As can see from Figure 2, the tooth head of the Elastic Teeth 3 formation chain tooth 2 that chain tooth 2 both sides are stretched out, the rear side of Elastic Teeth 3 then forms the thinner neck of chain tooth 2, at the rear side neck place of described Elastic Teeth 3, described location indentations 24 is set, after chain tooth 2 drawing of two straps 1, in the location indentations 24 of an Elastic Teeth relative side chain tooth 2 of 3 insertion of described chain tooth 2.
As shown in Figure 3 and Figure 4, during in order to make slide fastener drawing, the chain tooth 2 of two opposite sides is easy to engagement, and facilitate Elastic Teeth 3 insertion and deviate from location indentations 24, described Elastic Teeth 3 is provided with inclined-plane or sphere, and by inclined-plane or sphere, Elastic Teeth 3 is easy to enter the rear space of the opposite Elastic Teeth of two chain teeth 23 and inserts in location indentations 24, and slide fastener is when separating, Elastic Teeth the 3 also easy neck from location indentations 24 and opposite side slide fastener is deviate from.
As shown in Figure 5, in the present embodiment, Elastic Teeth 3 is arranged on fixed cover 4 two ends, and fixed cover 4 is built with spring 5, and fixed cover 4 is loaded in the installing hole of chain tooth 2.By fixed cover 4 structure, first to Elastic Teeth 3, spring 5 and fixed cover 4 portion dress can be formed integral component, convenient processing.Described Elastic Teeth 3 comprises ball head 31 and guide part 32, ball head 31 is that semicircle is spherical, guide part 32 is the cylindrical sections connected with ball head 31, the endoporus of cylindrical section and fixed cover 4 is suitable, play guide effect, ensure that Elastic Teeth 3 is not crooked, and the two ends of fixed cover 4 have the reducing 41 of Internal Spherical Surface annular, the reducing 41 of Internal Spherical Surface annular, for limiting Elastic Teeth 3, prevents Elastic Teeth 3 from skidding off fixed cover 4.As shown in Figure 3, be recessed into chain tooth 2 rear in the middle part of the rear end of chain tooth 2 liang of step surfaces and form the circular groove 25 of semi-surrounding, location indentations 24 is arranged on the step surface in this groove 25, with the shape of Elastic Teeth 3 adaptably, location indentations 24 is sphere pit.The spherical Elastic Teeth of semicircle 3 matches with sphere pit, Elastic Teeth 3 adaptivity are good, automatic adjustment is without dead angle, slide fastener drawing is lighter, strap 1 not arch camber, not wrinkle, no matter slide fastener how torsional bending, an Elastic Teeth 3 chain tooth 2 also can not deviating from be meshed because of offseting with location indentations 24, engagement between adjacent chain tooth 2 is solid and reliable, not easily deviates from and produces quick-fried tooth.
Can see from Fig. 4 and Fig. 5, described fixed cover 4 and chain tooth 2 are provided with through hole 6, both make in fixed cover 4 outer through with chain tooth 2 by the through hole 6 connected, through hole 6 forms exhaust, discharge opeing and observation passage, chain tooth 2 is after electroplating work procedure, and plating solution discharges by through hole 6, and Elastic Teeth 3 is when inwardly retracting, air in chain tooth 2 discharges and pressure release by through hole 6, and through hole 6 can also as observing passage.
The present invention is on the two sides in chain tooth 2 tooth head width direction, symmetrical telescopic Elastic Teeth 3 is set, after two side chain teeth 2 engage, Elastic Teeth 3 can be inserted in the location indentations 24 of relative side chain tooth 2, Elastic Teeth 3 due to the effect of flexible member can the automatic telescopic adjustment according to the shape of the chain tooth 2 that is meshed and position, thus there will not be the drawing locking problem caused because of chain tooth 2 dimensional accuracy and quality of fit, the light slippery of drawing substandardly not to affect by tooth head is shaping, slide fastener Convenient man power, and not by the impact that strap 1 shrinks, spell and not arch camber wrinkle mutually between two between the slide fastener that can realize same size.
These are only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
