Abstract

The utility model discloses a novel plastic-steel button. The utility model is composed of a rivet, a male button and a female button, wherein, a cylinder is arranged on the basal disc of the male button, the middle of the male button is provided with a groove and a through hole, the top end of the male button is provided with a plurality of outer flanges, and the utility model is divided by symmetrical square grooves. A lug boss is arranged on the basal disc of the female button, the middle of the lug boss is provided with a concave circular groove and a through hole, and the top end of the concave circular groove is provided with an annular inner flange. The utility model can simplify the manufacturing technique of the button, particularly in that the die sinking difficulty of the concave circular groove of the female button is obviously lowered; the utility model is labor-saving and time-saving; the utility model is reliable in locking and small in unlocking force, and that gets the button and the connecting-objects free from damage.

Description

Plastic-steel push button

The utility model relates to a kind of snap-fastener, is meant a kind of new structure plastic-steel snap-fastener of simplified manufacturing technique effectively especially.

Referring to Fig. 1, the structure of existing plastic-steel snap-fastener is as follows: it is buckled by sun and cloudy the button formed.There are several outward flanges on the top of sun button cylinder, and there is the inward flange of equal number on the top of cloudy button groove.During fastening, by means of the elasticity of plastic-steel, the cylinder of sun button is inserted in the recessed circular groove of cloudy button, inside and outside flange is fastened by this.When triping, firmly extract the cylinder of sun button, because institute's external force of executing causes snap-fastener and the damage that is connected object greatly easily, even more serious is the manufacturing process complexity, and particularly the moon is detained the inward flange on the recessed circular groove.The difficulty of die sinking is big, and the precision height is time-consuming.

The purpose of this utility model is that a kind of plastic-steel snap-fastener will be provided, and it can simplify its manufacturing process effectively, reduce to fasten or required external force when triping.

The purpose of this utility model is achieved in that the new snap-fastener of plastic-steel is by rivet, sun button and cloudy button are formed, on the sun button basal disc cylinder is arranged, there are several outward flanges on the top of cylinder, fluted and through hole in the middle of it, on the basal disc of cloudy button boss is arranged, fluted and through hole in the middle of the boss, there is the inward flange of equal number on the groove top, the two fastens each other, it is characterized in that: several outward flanges on sun button cylinder top are to be separated by the square groove of being opened, and the inward flange on cloudy button groove top is a complete annulus.

The utility model makes the manufacturing process of snap-fastener owing to simplify the structure, simple being suitable for, precision is low, easy to manufacture, reduced the difficulty of die sinking, the time worker save time, the quantity of institute's evolution groove, the elasticity of plastic-steel is not fully exerted, can guarantees the reliability that fastens, can reduce fastening or the required external force of triping again significantly, thereby prolonged the service life of snap-fastener, do not damaged the connection object again.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the three-dimensional exploded view of existing plastic-steel snap-fastener.

Fig. 2 is the three-dimensional exploded view of the utility model embodiment 1.

Fig. 3 is the three-dimensional exploded view of the utility model embodiment 2.

The three-dimensional exploded view of Fig. 4 the utility model embodiment 3.

Fig. 5 is the utility model buckling state schematic diagram.

Referring to Fig. 2,5, the utility model embodiment 1, by rivet 1,2, sun button 5 and cloudy button 6 are formed.Rivet is identical with general snap rivets.On the basal disc 51 of sun button 5 cylinder 52 is arranged.There are two outward flanges 521 on the top of cylinder 52.Two outward flanges are separated into by square groove 53, its centre fluted 54 and through hole 55.On the basal disc of cloudy button 6 frustum is arranged, in the middle of the frustum a recessed circular groove 61 and a through hole 63 arranged, there is an annular inward flange 62 on the top of recessed circular groove 61.

Referring to Fig. 3,5, the utility model embodiment 2, by rivet 1,2, sun button 5 and cloudy button 6 are formed.The basal disc 51 of sun button 5 has a groove, and there is a cylinder 52 centre of groove.There are two outward flanges 521 on the top of cylinder 52, is separated into by square groove 53, and a groove 54 and through hole 55 are arranged in the middle of it.On the basal disc of cloudy button 6 cylinder is arranged.In the middle of the cylinder a recessed circular groove 61 and a through hole 63 arranged, there is the inward flange 62 of an annular on the top of recessed circular groove 61.

Referring to Fig. 4,5, the utility model embodiment 3, by rivet 1,2, sun button 5 and cloudy button 6 are formed.On the basal disc 51 of sun button 5 cylinder 52 is arranged.In the middle of the cylinder 52 groove 54 and through hole 55 are arranged, there are four outward flanges 521 on its top, is separated by the square groove 53 of four symmetries, the basal disc of cloudy button 6 is a small column, one big column is arranged on it, and there is a recessed circular groove 61 and a through hole 63 centre, and there is the inward flange 62 of an annular on the top of recessed circular groove 61.

Referring to Fig. 5, the method that snap-fastener is fixed on the

connection object

3,4 is as follows: connect the article of

object

3,4 for being suitable for, for example: ready-made clothes, raincoat, urine trousers, Stationery bag (box), briefcase, umbrella cover, sports equipment or the like.

At first on the corresponding edge that connects

object

3,4, get and give fixed corresponding hole 31,41.Hole 31,41 only passes through for

rivet bar

11,21.

The sun button is identical with the fixing means of cloudy

button.Rivet bar

11 or 21 be inserted into

hole

31 or 41 and the through hole 63 of the through hole 55 of sun button 5 or cloudy button 6 in, with each part compacting,

rivet bar

11 or 21 rivetings are lived with drift.

In sum, the new snap-fastener of this plastic-steel, outward flange 521 on the sun button 5 is to be separated into by the square groove of being opened 53, the inward flange 62 of cloudy button 6 is complete annulus, what fastening was taked is point, the line way of contact, and required precision is low, and this has just simplified the manufacturing process of snap-fastener, particularly reduced the die sinking difficulty of the inward flange 62 of cloudy button 6, saving of work and time.In addition, square groove 53 quantity of being opened can make the elasticity of plastic-steel snap-fastener be fully played, and can guarantee the reliability that fastens, can reduce fastening or the required external force of triping again significantly, thereby prolong the service life of snap-fastener, do not damage the connection object again.
