Description

Novel snap fastener

Technical Field

The utility model belongs to the technical field of the button technique and specifically relates to a novel primary and secondary is detained.

Background

The button of current high-end panel, molding design, the designer gets rid of mostly and uses traditional button and use the snap-fastener, has avoided the loaded down with trivial details of suture firstly, and secondly the suture is not pleasing to the eye enough.

The existing snap fastener is generally in a direct insertion type, so that the insertion end of the snap fastener is inserted into the clamping seat of the snap fastener, and in order to ensure that the connection is firmer, the teeth can be arranged on the clamping seat and the insertion end, so that the snap fastener is difficult to pull out after being inserted.

However, the snap fastener structure is limited by the volume of the male and female fasteners; in order to have sufficient contact points, the longitudinal volume of the male and female fasteners is generally designed to be slightly larger, resulting in a particularly prominent front and rear surface of the fastener on the article.

In order to further improve the appearance and firmness, a novel snap fastener is designed.

SUMMERY OF THE UTILITY MODEL

For solving the not enough among the prior art, the utility model aims at providing a novel primary and secondary is detained, aims at solving current primary and secondary and detains firm in connection degree and volume, pleasing to the eye problem that can't optimize.

In order to achieve the above purpose, the technical scheme of the utility model is that: a novel snap fastener comprises a fastener face and a fastener seat, wherein the lower end of the fastener face is provided with an insertion part, and the fastener seat is provided with an insertion slot; the insertion part is composed of at least two flexible sheets, and the surfaces of the flexible sheets are provided with a plurality of clamping teeth;

the slot is transversely provided with an interlayer communicated with the slot, and the interlayer is obliquely arranged; the interlayer is internally provided with a latch matched with the toughness pieces, and the slot is internally provided with a pressing part for pressing and separating each toughness piece to the interlayer.

Preferably, each of the flexible sheets of the insertion portion and the end portion of the pressing portion is provided with a guide surface.

Preferably, each flexible sheet of the insertion part is provided with a guide surface which is concave, and the end part of the pressing part is convex.

Preferably, the pressing part is a top rod arranged at the bottom of the slot and extends to the slot opening, and the interlayer is distributed on the side surface of the top rod.

Preferably, the lower layer of the interlayer is closer to the pressing part than the upper layer, so that the flexible sheet is better inserted into the interlayer in the case that the interlayer is thinner.

Preferably, the pressing part is connected with the lower layer surface of the interlayer.

Preferably, the interlayer is a ring-shaped layer.

Preferably, the insertion portion is formed by at least three flexible sheets distributed annularly.

Preferably, the outer surface of the flexible sheet and the upper layer surface of the interlayer are provided with mutually matched latch teeth.

Preferably, the fastening surface and the insertion portion are both made of copper.

The utility model has the advantages that: the snap fastener is more firmly connected, and the main body is more flattened after the snap fastener is fastened, the clothes are attached, the appearance is convenient, and the appearance is more attractive.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, a novel snap fastener comprises a fastening surface 1 and a fastening seat 2, wherein the lower end of the fastening surface 1 is provided with an insertion part, and the fastening seat 2 is provided with an insertion slot 3; the inserting part is composed of two flexible sheets 4, and a plurality of clamping teeth 5 are arranged on the outer surfaces of the flexible sheets 4;

the slot 3 is transversely provided with an interlayer 6 communicated with the slot 3, the interlayer 6 is a ring-shaped layer, and the interlayer 6 is obliquely arranged; the upper layer surface of the interlayer 6 is provided with a latch 5 matched with the toughness sheet 4, and a pressing part 7 for pressing and separating each toughness sheet 4 to the interlayer 6 is arranged in the slot 3.

The pressing part 7 is an ejector rod arranged at the bottom of the slot 3 and extends to the slot opening, the end part of the ejector rod is a convex surface, the inner end of each toughness sheet 4 of the inserting part is provided with a guide surface 8 which is a concave surface, the interlayer 6 is distributed on the side surface of the ejector rod, and the lower layer surface of the interlayer 6 is closer to the pressing part 7 than the upper layer surface.

The utility model utilizes the compression part 7 which is arranged in the slot 3 and used for compressing and separating each toughness piece 4 to the interlayer 6; when in use, as with a common snap fastener, when the fastening surface 1 is fastened to the fastening seat 2, the insertion part firstly punctures the surface of an object (the outermost latch 5 can be used as a needle head part); the convex surface of the ejector rod struts each toughness sheet 4, so that when the ejector rod is pressed down again, the toughness sheets 4 are inserted into the interlayer 6 along the lower layer surface of the interlayer 6, and only one-way motion can be realized by utilizing the latch 5 of the two parts.

After the pressing, the flexible sheet 4 is used for resilience force due to the flexibility, so that the buckle base 2 is folded by the latch 5, and the connection between the buckle base and the buckle base is always firm; due to the structural design, after the longer inserting part and the original buckle surface 1 with larger volume are compressed, the flexible sheet 4 extends transversely, so that the longitudinal volume of the buckle seat 2 does not need to be too deep, the flattening of the buckle is realized, the buckle can be more attached to articles, the modeling is convenient, and the appearance is more attractive; the contradiction between the length of the insertion part, the volume of the button, the aesthetic degree and the connection firmness is solved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
