Abstract

Disclosed is a side opening fastener comprising a box sub and a pin sub, wherein, the box sub is arranged an opening on the front which is extended in both sides into two slant faces with locked unit and a side outlet and the distance between the two slant faces is enlarged gradually, the pin sub is arranged two resilient arms with grooves which can be fastened in the locked unit of the slant face and the resilient arms can stretch into the side outlet on the slant face and the end of the resilient arms is touched into the inside of the grooves, a resilient unit is arranged inside of the resilient arms which can be pressed to detached the pin sub form the box sub, and the resilient arms broken or reshaped under the condition of overexertion are avoided for the reasons of that the tension arm of the resilient arm is quite long, a acting force is exerted on the resilient arms when the resilient unit is pressed to make the pin sub is disintegrated with the box sub easily.

Description

Other open type fastener

Technical field

The utility model is a kind of other open type fastener, refers to that especially pin thread is easy to break away from the other open type fastener of box, and this fastener can prevent the elastic arm fracture or the situation of deformation takes place, and also can effectively reduce spent material cost.

Background technology

Institute's Woven belt buckle that is used in is mostly all with public affairs now, the matrix fastener is main, knapsack for example, suitcase, shoulder harness, with cover buckle or other needs the fixing article of ribbon etc. before the knapsack, please consult Fig. 5 and shown in Figure 6 simultaneously, three-dimensional exploded view and side cutaway view for the prior art fastener, find out by knowing among the figure, this kind prior art fastener mainly respectively is provided with elastic arm A11 in pin thread A1 two sides, and between two elastic arm A11, be provided with a body of rod A12, box A2 front end then is provided with an opening A21, and be provided with a guide rail A22 in the opening A21, elastic arm A11 and the body of rod A12 of pin thread A1 can be pushed by the opening A21 place of box A2, and make the guide rail A22 of the body of rod A12 of pin thread A1 in alignment with box A2, after waiting to push, the binding block A13 that can make elastic arm A11 end is snapped in by the side opening A23 place of box A2 two sides, and makes the formed short slot A14 of turnover face between binding block A13 and elastic arm A11 be held in side opening A23 edge wall A231 to form the location.

Yet, though above-mentioned male and female button can reach the effect of fastening, but still have following some major defect, now be analyzed as follows:

(1) in the fastener of above-mentioned prior art, behind pin thread A1 and box A2 fastening, then the terminal set binding block A13 of elastic arm A11 will protrude in the set side opening A23 of box A2, and binding block A13 protrudes in the part of side opening A23, to allow the user in having a mind to or being pressed into binding block A13 under the situation unintentionally easily, and then cause separating of pin thread A1 and box A2, cause the user need expend the fastening situation that a large amount of spirit removes to confirm pin thread A1 and box A2.

(2) in the fastener of above-mentioned prior art, when pin thread A1 is pushed in box A2, the body of rod A12 that very easily on business detains the two elastic arm A11 of A1 and central authorities fails to align fully the guide rail A22 in the opening A21 of box A2 and the dislocation state takes place, and then the inconvenience when causing the user to carry out snap action again, cause elastic arm A11 and body of rod A12 to break easily and produce deflection deformation or damage.

(3) in the fastener of above-mentioned prior art, because the formed short slot A14 of turnover face between elastic arm A11 and binding block A13 need utilize side opening A23 edge wall A231 to position, cause box A2 need expend wide variety of materials and make side opening A23, and then cause the extra increase of material cost.

Therefore, the utility model is in view of above-mentioned defective, and the spy is engaged in the industry research and development experience for many years with it, and via constantly studying and revising, the side designs other open type fastener, in order to improve the prior art constructions defective.
