Description

clasp

technical field

The invention relates to a buckle structure, in particular to a technical field capable of quickly combining or separating two objects.

Background technique

The invention of the hook and loop provides people with a very convenient life, and the application of the hook and loop can also be seen in various items. Please refer to Fig. 1, the existing Velcro 1 includes a female buckle 11 and a child buckle 12, wherein the female buckle 11 is provided with a plurality of circles 111, and as the child buckle 12 is provided with a plurality of The hook body 121 can achieve the purpose of fastening the female buckle 11 and the child buckle 12 by hooking a plurality of hooks 121 in a plurality of loops 111 . The existing hook and loop 1 has at least the following defects:

1. When the hook and loop 1 is applied to textiles, such as underwear, the hook body 121 and the ring body 111 are very easy to hook cotton wool, resulting in the destruction of the silk thread structure of the underwear, which is extremely unsightly; Velcro 1, the effect of gluing will be greatly reduced.

2. When the traditional hook and loop 1 is torn apart, it often causes great high-frequency noise, which makes people feel harsh.

3. Because the traditional Velcro 1 includes the hook body 121 structure, if the human body accidentally contacts it, it is easy to scratch the skin.

In view of this, the inventor thinks that the traditional hook and loop 1 should still have room and necessity for innovation and improvement, so he specially develops this invention with research and development; he expects to improve the many defects of the existing hook and loop through the proposal of the present invention. This kind of fastening product can be more perfect, ideal and practical.

Contents of the invention

In order to improve the many defects of the above-mentioned traditional hook and loop, the main purpose of the present invention is to provide a buckle structure, which has the same action as the traditional hook and loop. In order to obtain the same effect, but the present invention has the advantages of no yarn snagging, low noise and no scratching of the skin, lighter, thinner, transparent and invisible.

In order to achieve the above purpose, the specific content of the present invention is: the snap-on buckle includes a first body and a second body.

The first body includes a plurality of first recesses and first protrusions arranged at intervals in an array, that is, the adjacent side of each first recess is the first protrusion, and the adjacent side of each first protrusion is first recess.

The second body includes a plurality of second recesses and second protrusions arranged at intervals in an array, that is, the adjacent side of each second recess is the second protrusion, and the adjacent side of each second protrusion is second recess.

The volume of the first recess is approximately close to the volume of the second protrusion, and the first recess can provide the vertical insertion of the second protrusion; and the volume of the second recess is approximately the same as the volume of the first protrusion Closely, the second recess can provide the vertical embedding of the first bump. Each of the first concave portion, the second bump, and the second concave portion has the same shape as the first bump, at least including a circle or a polygon, and the polygon may be a rectangle, but not limited thereto.

The first body and the second body can be made transparent as required.

Detailed ways

With regard to the structure and composition of the snap-fit fastener of the present invention, and the effects thereof, a preferred embodiment of the present invention is described in detail as follows with reference to the accompanying drawings.

First please refer to Fig. 2 and Fig. 3, the snap-fit fastener 2 of the present invention includes a first body 21 and a second body 22; wherein, the first body 21 includes a plurality of groups of The first recess 211 and the first protrusion 212, the adjacent side of each first recess 211 is the first protrusion 212, and the adjacent side of each first protrusion 212 is the first recess 211; the second body 22 includes multiple The second recesses 221 and the second protrusions 222 arranged at intervals in groups, that is, the adjacent side of each second recess 221 is the second protrusion 222, and the adjacent side of each second protrusion 222 is the second recess 221 . The volume of the first recess 211 is approximately close to the volume of the second protrusion 222, the first recess 211 can provide the second protrusion 222 to be vertically embedded and tightly fit; and the volume of the second recess 221 is similar to the volume of the first The volume of a protrusion 212 is approximately close, and the second recess 221 can provide that the first protrusion 212 is vertically embedded and can be tightly fitted; each first recess 211, second protrusion 222, second recess 221 and the first protrusion The shapes of 212 are the same, including at least a circle or a polygon, and the polygon may be a rectangle, but not limited thereto.

As shown in Fig. 4, when the first body 21 and the second body 22 in the present invention are to be combined, the two are made to be parallel to each other, and then the first recesses 211 and the second protrusions 222 are fitted together. And tight fit, and each second recess 221 and each first protrusion 212 are fitted and tightly fitted with each other, which can achieve the purpose of combining the first body 21 and the second body 22; due to the multiple arrays of each other The concave-convex structure has a tight fit relationship, so the first body 21 and the second body 22 can be inseparable to achieve the purpose of tight combination. The application range and status of the present invention are roughly the same as those of the existing hook and loop fasteners.

When the first body 21 and the second body 22 are to be separated, the first body 21 and the second body 22 need to apply force parallel to each other, so that each second protrusion 222 is disengaged from each first recess 211, Moreover, each first protrusion 212 is also disengaged from each second concave portion 221 , so as to release the fitting relationship between the first body 21 and the second body 22 to achieve the purpose of separation.

Please refer to FIG. 5 again, which shows the anti-loosening mechanism of the present invention. If the first body 21 is to be detached from the second body 22 in a cable-pull manner, the sides of the plurality of first protrusions 212 will be blocked by the plurality of second protrusions 222, resulting in great resistance. , and then have a good anti-loosening effect.

When the present invention is implemented, its thickness can be made into about 1.3~1.5mm, which is lighter and thinner than the 3mm of the existing hook and loop fastener, and it can also be made into a transparent shape by injection molding, which is more beautiful. In addition, the two bodies of the present invention can have the same structure, and only need to prepare a single structure during production, which does not require the female buckle to cooperate with the child buckle like the traditional hook and loop; moreover, the present invention uses injection molding It is made in molding mode, suitable for mass production, and the cost is lower than that of traditional hook and loop fasteners (traditional hook and loop fasteners need to be braided, the production capacity is lower than the present invention, and the cost is higher than the present invention). Noise, without damaging clothing or skin, full of progress.

Although the present invention is described by the foregoing embodiments, the form and details can still be changed without departing from the spirit of the present invention, and can be understood by those skilled in the art. The aforementioned preferred embodiments of the present invention are only one of the modes that can be specifically implemented through the principle of the present invention, but are not limited thereto, and should be defined in accordance with the claims.
