Abstract
The utility model relates to a fastener, which is composed of a convex fastening end and a fastening seat. The front end of the convex fastening end forms a convex arc-shaped elastic frame; the end of the elastic frame is provided with a clamped tenon; the fastening seat is a hollow seat body of an inserted groove corresponding to the convex fastening end; the fastening seat is used for inserting the convex fastening end to form the fastening state; the surface of the fastening seat is provided with an elastic and circular press fastener; the front end of the press fastener which is similar to a circular shape is provided with an arc-shaped convex portion on the internal wall of the inserted groove; two side walls on the end of the inserted groove can form a symmetrical and convex side, and the end next to an elastic fastening sheet is provided with a movable rod on the convex fastening end. The utility model not only can make the fastener firm, but also can rapidly and easily complete fastening and tripping motions.
Description
The utility model relates to a kind of fastening device, refer to especially a kind of simple in structure but firmly, volume is little, the intensity height, cost is low, and the fastener that can finish snap close easily and trip fast.
No matter is suitcase at present, knapsack, belt, briefcase, leather trunk, and travelling bag or the like all need have buckle structure such as fastener to reach the purpose of locking.Yet general fastener is not a snap close step trouble effort, is the structural strength deficiency, or gets loose phenomenon easily.
It is a kind of simple in structure but firmly, volume is little that the purpose of this utility model is to provide, the intensity height, and the fastener that cost is low is to overcome the above-mentioned shortcoming that prior art exists.
For achieving the above object, the utility model is taked following technical scheme:
A kind of fastener, it comprises: a protruding end of thread, its front end form a convex arc shaped elastic shelf, and in the middle of protruding end of thread, the elastic shelf upper extremity is provided with a trip; An and buckling base, it is one to have the hollow base frame of the slot corresponding with protruding end of thread, it forms buckling state in order to the protruding end of thread of pegging graft, the buckling base surface is provided with the circular clinching of elasticity, at slot inwall subcircular clinching front end one arc protuberance is set, the nearly slot-open-section of this arc protuberance is thinner, and then thicker near the circular clinching front end of elasticity, the two side that is positioned at the slot end forms the convex side of a symmetry.
Above-mentioned purpose of the present utility model, can also further realize by following technical measures:
Short round cramp end can be provided with a motion bar on the described protruding end of thread, one end of this motion bar is fixed on a side of protruding end of thread, and the other end then protrudes in outside the protruding end of thread, and the below is provided with a stator in the middle of this motion bar, motion bar can push away nearly trip, makes stator be positioned at elastic shelf end below.Elastic shelf can't stressedly press down when circular clinching presses down, and gets loose because of pushing circular clinching accidentally when the snap close state to prevent fastener.
The utility model embodiment is described with reference to the accompanying drawings as follows:
Fig. 1 is the perspective view before the utility model embodiment snap close.
Fig. 2 is the perspective view behind the utility model embodiment snap close.
See also Fig. 1, the perspective view before the utility model embodiment snap close.It comprises protruding end of thread 10 and buckling base 20.The end of its convexity end of thread 10 forms a convex arc shaped elastic shelf 11, is positioned in the middle of the protruding end of thread 10, and elastic shelf 11 upper extremities are provided with a trip 12; And buckling base 20 is one to be provided with the hollow base frame of the slot 21 corresponding with protruding end of thread 10, it forms buckling state in order to the protruding end of thread 10 of pegging graft, buckling base 20 surfaces are provided with the circular clinching 22 of elasticity, at slot 21 inwall subcircular clinchings 22 front ends one arc protuberance 23 is set, these arc protuberance 23 nearly slot-open-sections are thinner, more then thicker near circular clinching 22 front ends of elasticity, the two side that is positioned at slot 21 ends is formed with the convex side 24 of a symmetry.
By above-mentioned structural design, protruding end of thread 10 is inserted buckling base 20, owing to the trip on the elastic shelf 11 12 arc protuberance 23 inconsistent elastic shelfs that make with buckling base 20 are pressed down, pressing down of elastic shelf 11 reaches maximum when treating that trip 12 is terminal and contacting with the thick of arc protuberance 23.When trip 12 ends leave arc protuberance 23, elastic shelf 11 reverts to the original not state by compression the time, this moment elastic shelf 11 leading edges and buckling base 20 the inconsistent and pressurized of the convex lateral margin 24 of slot 21 ends, yet because the trip 12 of elastic shelf 10 is stopped by arcuation protuberance 23, so protruding end of thread 10 is firm buckling state with buckling base 20, as shown in Figure 2.Treat the circular clinching 22 of buckling base 20 is pressed down, so that trip 12 pressurizeds, this moment is because trip 12 is stopped by arcuation protuberance 23 no longer, elastic shelf 11 leading edges because of protruding end of thread 10 are subjected to 24 extruding of convex side to make elastic shelf 11 be elastic compression again, thereby make protruding end of thread 10 eject backward, be able to finish easily fast the action of triping.
Nearly trip 12 ends can be provided with a motion bar 13 on the protruding end of thread 10 of the utility model fastener, one end of this motion bar 13 is fixed on a side of protruding end of thread 10, the other end then protrudes in outside the protruding end of thread 10, the below is provided with a stator 131 in the middle of this motion bar 13, motion bar can push away nearly trip 12, make stator 131 be positioned at the terminal below of elastic shelf 11, elastic shelf 11 can't stressedly press down when circular clinching 22 was pressed down, and got loose because of pushing circular clinching 22 accidentally when the snap close state to prevent fastener.
Above-mentioned specific embodiment is to be used for describing in detail the purpose of this utility model, characteristics and effect, for the personage who is familiar with this technology, according to the above description, may do equivalence change and modification to this specific embodiment, and do not break away from creation spirit of the present utility model, must belong to technology category of the present utility model.
