Main purpose of the present utility model promptly is to provide a kind of fastener, and this buckle structure can overcome the above-mentioned shortcoming of mentioning, simultaneously the higher confidence level of tool.Improving according to fastener of the present utility model, is to comprise a female element with internal chamber, one can enter or leave female element freely male element and one constitute in order to the coating member of accommodating above-mentioned member.Cloudy, at least has one between male element after their combinations, slotted eye is pulled out in pushing away of location overlap, so that allowing to be arranged on one on the coating member inner face pushes away the portion of pulling out and enters, allow described coating member with cloudy, male element is set up the state that the complete driving fit in slotting knot in aggregates position does not have headspace, use and force each connector when being subjected to external force to collide or twist, the restricted distortion of energy one, and then the path that keeps being separated therebetween is for changing synchronously, the interelement relative deformation of collocation that will be correlated with reduces to minimum, even eliminate, so, design at more old-fashioned fastener, this buckle structure is that mean can be with the moon, male element reduces to minimum in the relative deformation who is subjected to be produced after the external force effect or diversity factor, and is excessive and produce the problems referred to above with the distortion difference of avoiding each inter-module.
According to fastener of the present utility model, this male element front end is to comprise a deep-slotted chip breaker and a unfilled corner, and after in male element enters female element, described unfilled corner can flexible system be combined on female element internal chamber one crestal line, reaches the location indicative function.
For the novel features that the utility model had, and other purposes and effect, be described in detail as follows below in conjunction with accompanying drawing:
Fig. 1 is common fastener three-dimensional exploded view.
Fig. 2 is a three-dimensional exploded view of the present utility model.
Fig. 3 is the embodiment profile before the utility model yin, yang member is not detained knot.
Fig. 4 is the action embodiment profile in yin, yang member button when knot of Fig. 3.
Fig. 5 is the embodiment profile after the utility model coating member coats the yin, yang member.
See also Fig. 2, Fig. 3, fastener of the present utility model, it comprises a coating member, is with Ref. No. 10 representatives; It has the slotting portion 12 of a pushing and drawing shape on an inner face 11 and the inner face 11; Deposit among the embodiment that is adopted, there is a shaft contact 15 rear end of coating member 10, makes it to become movable relation freely in order to articulate female element 20; Coating member 10 comprises both sides wall 13, has into the shape groove 14 of symmetrical shape on its limit wall 13, in order to rabbet on the geosynclinal block 31 on male element 30 both sides.
Among Fig. 3, Fig. 4, when 20,30 attempts of yin, yang member fasten, the arm 32 of male element 30 is can be inserted in easily in the chamber 21 of female element 20 on same axis, resist on the crestal line 24 of chamber 21 up to unfilled corner 34, this program also forces pushing away of yin, yang member 20,30 to pull out aperture 23,35 and overlaps at same position, has preliminary fastening effect.In preferred embodiment, only need press down coating member 10, making pushing and drawing shape insert portion 12 enters pushing away when overlapping and pulls out aperture 23,35, and make shape groove 14 buckles on the geosynclinal block 311 of male element 30, promptly as Fig. 5 representedly with yin, yang member 20,30 state that is combined into one, so, with regard to above-mentioned structural design, the preliminary combination that clearly can find 20,30 of yin, yang members of the present utility model is extremely slight and directly easy, even if also can pull away mutually easily under the serious state of modification; But after seeing through being laminated with of coating member 10, inserting 12 pairs in portion by pushing and drawing shape pushes away and pulls out aperture 23,35 sleeve, and the dual fastening of 14 pairs of geosynclinal blocks 311 of shape groove, reach very firm certain combination, the fastening reliability is high, the distortion even if the state that fastens fully at three assemblies is impacted, the distortion of coating member 10 is also depended on internals fully and is formed, otherwise promptly break away from voluntarily, as easy as rolling off a log can lifting opened release to the moon, the fastening of male element, reach the effect of ejection escape, this helps the fastener improvement to be used in safety cap, band or mountain-climbing, during the bracelet effect aspect of article such as Knapsack bag, its security is further enhanced, also be coating member 10 and the moon, male element 20, not only set up a defencive function that coats complete body between 30, make the pre-degree of independent deformation after tool does not collide between each member, enable to give coating member 10 and the moon, male element 20,30 will reduce to minimum being subjected to clashing into the relative deformation who is caused when excessively pullling with band, disengaging approach between each phase accessory is kept because of its deform in same pace fills part, and each element breaks away from path autoheterosis and the puzzlement that can't be separated as unlikely generation such as the tradition; In other words, the coating member pushing and drawing shape insert portion 12, shape groove 14 push away with the yin, yang member respectively pull out mouthfuls 23,35, geosynclinal block 31 does closely knit cooperating, even the bump of external force is even as big as producing distortion, they also will set up a kind of synchronous offset phenomena; Coating member 10 still can be opened easily, and reach the effect of triping.
