Description

Novel snap fastener

Technical Field

The utility model relates to a snap-fastener technical field, concretely relates to novel snap-fastener.

Background

Existing snap fasteners include male and female buttons.

When the snap fastener is assembled, a through hole is punched on articles such as clothes, shoes, hats and the like, the female fastener passes through the through hole, and then the male fastener and the female fastener are riveted together through special mounting tools such as a die, a hammer and the like.

The male buckle and the female buckle of the riveting structure need to adopt special mounting tools during assembly, and the female buckle is easy to break down during knocking.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel snap-fastener to prior art's defect and not enough, have the assembly fastening and be difficult for the advantage that collapses.

In order to achieve the above object, the utility model adopts the following technical scheme: a novel snap fastener, including the pin thread and the box of lock of each other, the pin thread includes: the positioning device comprises a first face shell and a positioning column arranged on the first face shell; the box includes: the second face shell and the lug boss are arranged on the second face shell; the boss is provided with a positioning hole for the positioning column to penetrate through, and the side edge of the boss is provided with a through side hole.

The utility model is further provided with a lug with a diameter larger than that of the positioning column at the top end of the positioning column; the positioning hole is gradually reduced downwards along the inner wall; the diameter of the bump is smaller than or equal to the diameter of the upper side of the positioning hole; the diameter of the bump is larger than that of the lower side of the positioning hole.

The utility model discloses further set up, the boss inboard seted up with the tension hole that the locating hole switched on.

After the technical scheme is adopted, the utility model discloses beneficial effect does:

in the utility model, the convex block is arranged at the top end of the positioning column, and the positioning hole is arranged to be gradually reduced downwards along the inner wall, so that the male buckle and the female buckle are more tightly riveted and cannot fall out; and through the side holes which are arranged on the side edges of the bosses, when the male buckle and the female buckle are riveted, the side edges of the female buckle have tension and cannot be broken.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.

The present embodiment relates to a novel snap fastener, as shown in fig. 1-3, comprising a male snap fastener 1 and a female snap fastener 2 which are fastened to each other. The pin 1 includes: the first casing 11, and, locate reference column 12 on first casing 11. The box 2 includes: and a second surface case 21, and a boss 22 provided on the second surface case 21. The boss 22 is provided with a positioning hole 221 for the positioning post 12 to pass through. The side of the boss 22 is provided with a through side hole 222. When the male buckle 1 and the female buckle 2 are riveted, the male buckle 1 is pressed into the female buckle 2, that is, the positioning column 12 passes through the positioning hole 221. Be equipped with the side opening 222 that link up through the side at boss 22 for when pin 1 and box 2 riveted, the side of box 2 has tension, is difficult for being collapsed, has improved the yields of product by a wide margin.

Further, as shown in fig. 1-3, a protrusion 121 having a diameter larger than that of the positioning post 12 is disposed at the top end of the positioning post 12. The positioning hole 221 is tapered downward along the inner wall. The diameter of the bump 121 is smaller than or equal to the diameter of the upper side of the positioning hole 221; the diameter of the protrusion 121 is larger than the diameter of the lower side of the positioning hole 221. When the male buckle 1 and the female buckle 2 are riveted, the male buckle 1 is pressed into the female buckle 2, that is, the positioning column 12 passes through the positioning hole 221, and the protrusion 121 abuts against the lower side of the positioning hole 221. Because the top end of the positioning column 12 is provided with the bump 121, the positioning hole 221 is arranged to be tapered downwards along the inner wall, the diameter of the bump 121 is smaller than or equal to the diameter of the upper side of the positioning hole 221, and the diameter of the bump 121 is larger than the diameter of the lower side of the positioning hole 221, so that the positioning column 12 can pass through the positioning hole 221 more easily, cannot fall out after passing, and is very tight. In the present embodiment, the diameter of the bump 121 is equal to the diameter of the upper side of the positioning hole 221.

As shown in fig. 2, a tension hole 223 is formed inside the boss 22 and is communicated with the positioning hole 221, so that the female buckle 2 is not broken after the positioning post 12 is inserted into the positioning hole 221.

The working principle of the utility model is as follows: because the top of reference column 12 is equipped with lug 121, and locating hole 221 sets up to follow the downward convergent of inner wall for pin 1 and box 2 are very firm after the riveting, and through being equipped with thorough side opening 222 at the side of boss 22, set up the tension hole 223 that switches on with locating hole 221 in the boss 22 inboard again, make pin 1 and box 2 when riveting, box 2 has outside tension, is difficult for collapsing.

The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
