Abstract

The utility model relates to a button, which is composed of a hat-peg, a male fastener and a female fastener. A convex pole that is provided with a concave edge and that vertically extends outwards is arranged at a base end face of the male fastener, and a bearing socket that sinks inwards and that is provided with homogeneously distributing convex lips at the opening is arranged at the end face of the female fastener in correspondence with the convex pole of the male fastener. When the utility model is used, platellites that are to be connected and that are provided with through holes are respectively clamped by the hat-peg, the male fastener and the female fastener, and the flange of the male fastener is pressed into the bearing socket of the female fastener by means of the inherent flexibility of plastics or the metal button, and thus the two fasteners are connected into integration by a connecting body. When connected into integration, the male fastener and the female fastener are not totally affixed to each other, thus the utility model is easy in opening and closing, convenient in use, and low in cost.

Description

Push button

The utility model relates to a kind of snap-fastener.

The snap-fastener of commonly using is many to be made with plastics or metal, as shown in Figure 1, include a positive fastener and a cloudy fastener, this two fastener utilizes snap-fastener to be fixed on the plates to be connected respectively, utilize the mutual fastening of negative and positive fastener then, two plates are connected together, its structure is at the projection end of this sun fastener periphery, be provided with the protruding lip of predetermined number, and the periphery of the cloudy fastener pod opening corresponding with it also is provided with the protruding lip of predetermined number, when positive fastener and cloudy fastener fasten mutually, by coincideing mutually of both protruding lips, promptly can put the way of contact and closely snap together and can lightly untie; But this snap-fastener be owing to must be provided with the protruding lip of predetermined number at the projection end of positive fastener periphery, some difficulty of die sinking in productions, and more time-consuming taking a lot of work increased production cost, so make things convenient for inadequately.

The purpose of this utility model is that a kind of improved snap-fastener will be provided, this snap-fastener, and processing can reduce production costs easily.

The purpose of this utility model is achieved in that this snap-fastener is by snap-fastener and positive fastener with holes, cloudy fastener constitutes, on the pedestal end face of positive fastener, be provided with the projection that vertically stretches out and have flange, on the end face of cloudy fastener, corresponding with the projection of positive fastener, be provided with the pod that inwardly concaves and be evenly equipped with protruding lip at opening part, during use, utilize snap-fastener, the sun fastener, the plates to be connected that cloudy fastener will be installed with through hole are clamped respectively, utilize the intrinsic elasticity of plastics or metal snap-fastener, the flange of positive fastener is pressed in the pod of cloudy fastener, is about to two connected bodies and fuses.

Advantage of the present utility model, because of used positive fastener, its vertical outward extending projection is provided with complete flange, and upward die sinking is easy to make production, thereby reduces cost; And the elasticity that itself is had of utilizing flange and protruding lip, compressed the location, again because of the fastening of positive fastener and cloudy fastener, still be that point contacts with line, do not need the cooperation of degree of precision, only need exert oneself a little, both can be broken away from, and reason is not exerted oneself excessive and connected plates is torn, so easy to use.

The utility model concrete structure is provided by following examples and accompanying drawing thereof:

Fig. 1 is the snap-fastener exploded perspective view of commonly using (snap-fastener is not shown).

Fig. 2 is three-dimensional exploded view of the present utility model (snap-fastener is not shown).

Fig. 3 is a section constitutional diagram of the present utility model.

Below in conjunction with accompanying

drawing

3,4, describe in detail.

This snap-fastener is by snap-fastener 1,2, and positive fastener 5 and cloudy fastener 6 constitute, and on pedestal 51 end faces of positive fastener 5, are provided with vertical outward extending projection 52, in the end of projection 52, are provided with an annular lip 521, and projection 52 central authorities are provided with depression 53 and through hole 54; On the end face of cloudy fastener 6, corresponding with the projection 52 of positive fastener 5, be provided with a pod 61 that inwardly concaves, at the inner edge of pod 61, be provided with uniform protruding lip 62, the central authorities of pod 61 are provided with through hole 63.During use, will connect as raincoat, Stationery bag, briefcase, clothes, two sheet connected bodies 3 that sports equipment etc. use, 4, offer hole 31 at appropriate location, 41, make snap-fastener 1,2 protuberance 11,12

prolong hole

31,41 pass, with existing technology with connected

body

3,4 are fixed on positive fastener 5 and the cloudy fastener 6, then positive fastener 5 is buckled in the cloudy fastener 6, utilize the elasticity of plastics of fastener own or metallic article, flange 521 can successfully be pressed in the pod 61 of cloudy fastener 6, flange 521 is promptly blocked by protruding lip 62, be about to connected

body

3,4 fuse, at this moment because of 6 of positive fastener 5 and cloudy fasteners combining still for point and wire, there be not stopping fully of mating surface between the two, so when separating, only need firmly the protruding lip 62 of positive fastener 5 flange 521 with cloudy button 6 to be separated a little, can be not excessive with connected body 3 because of exerting oneself, 4 tear.
