Description

Snap button

The invention relates to a buckle structure which is mounted on a workpiece to be processed to form a buckle, and particularly relates to a fastener improvement capable of maintaining a set snap fit relationship in different production environments or use environments.

Nowadays, the use of buckles is very common. It can be applied to different kinds of shoes, bags, clothes, bags and other different types of items. It will be used with different fastening structures and different fastening methods. Please refer to Figure 1. It is shown that the conventional snap fastener 10 of the existing snap structure has a large bearing surface 101, and a tubular body protrusion 102 is protruded from the center, and the male fastener 11 also has a bearing surface 111, and the center is convexly disposed. The semi-circular projections 112 are engaged with the tubular body studs 102, so that the female fasteners 10 and the male fasteners 11 can be engaged and fixed.

However, at present, the existing snap fasteners are not all directly molded by plastic materials, otherwise the all-metal design is adopted, but the snap-fit structure formed by the plastic material injection molding will cause the female fasteners due to the difference in the temperature at the time of manufacture and the subsequent cooling state. The misalignment between the 10 and the male fasteners 11 and the use of different regions such as the tropical region and the low zone of the cold zone may also cause the influence of the heat expansion and contraction between the female fastener 10 and the male fastener 11 . And there is a problem with the snap.

However, the snap-on structure of the all-metal design can reduce the error caused by the production and the influence of the ambient temperature. However, the manufacturing method of the metal snap is complicated, and most of the metal fasteners must be additionally plated to avoid the external plating. Surface oxidation reaction, therefore, the extra plating process caused the birth The cost of production has increased, and nowadays environmental protection awareness is on the rise. After the electroplating, the snaps will not be recycled, and the subsequent pollution will still cause a certain degree of pollution to the environment.

In view of the fact that traditional snaps, whether plastic or metal, still have the aforementioned deficiencies, it is necessary to design an innovative structural snap to improve the current deficiencies.

The main object of the present invention is to provide a snap fastener capable of maintaining the strength of the buckle, so that the snap fasteners completed in different production environments or the buckles actually applied in various climatic environments can be used for the male and female buckles. The docking relationship between the two is not too tight or too slack, so that the snaps are kept in an optimal state of use.

In order to achieve the above object, the snap fastener of the present invention is mainly composed of a male buckle, a female buckle and a pusher.

In a preferred embodiment, the male buckle has a first disk body and extends outwardly from the first disk body to form a buckle portion; the female buckle has a second disk body and is formed by the second disk Extending outwardly from the body to form a fastening portion that cooperates with the buckle portion, wherein the fastening portion is formed by a plurality of fitting blocks surrounding the outer periphery of the fastening portion; and the pushing member is disposed around the female buckle The outer peripheral side of the clasp portion is in contact with the fitting block, and the thrust of the fitting block from the outside to the inside is provided.

Wherein, the engaging block has a first neck portion, and the first neck end portion extends toward the inner side and the outer side respectively to form a first hook portion and a second hook portion, and the first hook portion and the first hook portion a neck portion and a second disk body together form a first card slot for the buckle portion to be engaged, and the second hook portion, the first neck portion and the second disk body are additionally formed with a pushing member A second card slot that fits.

Further, when the size of each of the fitting blocks is fixedly uniform, the above-mentioned pushing members can be pressed against a partial range or a full range of the outer circumference of each of the fitting blocks. However, if the above-mentioned inset portion is made of two or more The fitting blocks of the same size are arranged at different intervals to form different outer diameters, and the pushing members can also be pressed against a partial range or a full range of the outer circumference of a part of the fitting blocks.

In another preferred embodiment, the male buckle has a first disc body that is fitted with the fabric body, and extends outwardly from the first disc body to form a latching portion, and the latching portion is engaged by a plurality of latching portions. The block has a second disk body that is fitted with the cloth body, and extends outwardly from the second disk body to form a fastening portion that cooperates with the buckle portion; and the pushing member The inner peripheral side of the buckle portion of the male buckle is wound and abuts against the engaging block to provide tension of the engaging block from the inside to the outside.

Wherein, the engaging block has a second neck portion, and the second neck top end extends toward the inner side and the outer side respectively to form a third hook portion and a fourth hook portion, and the third hook portion and the third hook portion The second neck portion and the first disk body together form a third card slot for the push-on member to be engaged, and the fourth hook portion, the second neck portion and the first disk body are additionally formed with the above-mentioned fastening portion. A mated fourth card slot.

Similarly, when the size of each of the engaging blocks is fixed, the pushing member contacts a partial range or a full range of the inner circumference of each engaging block for pressing. However, if the locking portion is arranged by two or more different sizes of engaging blocks to form different outer diameters, the pushing member may be pressed against a partial range or a full range of the inner circumference of a part of the engaging blocks.

In the above two preferred embodiments, the first disk body and the second disk body are respectively provided with through holes for assembling the rivets, and the peripheral edges of the through holes extend outward to form an increased strength surrounding wall, and the first disk The body and the surface of the second disk body are respectively provided with at least one non-slip bump, whereby the two rivets are respectively inserted into the through holes of the first disk body and the second disk body, so that the present invention can be directly buckled It is fixed on the object to be processed.

In addition, the first disc body and the second disc body may respectively be provided with a plurality of sewing openings for sewing the seams of the sutures, so that the sewn thread can pass through the sewing openings, so that the snap button of the present invention is also It can be directly sewn on the workpiece to be processed.

The snap fastener of the present invention can be selectively installed around the outer circumference of the inner peripheral portion of the buckle portion of the male buckle or the female buckle of the female buckle, so that the pusher can abut the plurality of engaging blocks of the buckle portion, and provide The tension from the inside to the outside, or the plurality of fitting blocks abutting against the buckle portion by the pushing member, provides an outwardly directed thrust. In this way, the mating relationship between the male and female buckles is not too tight or too slack, so that the snaps are kept in an optimal state of use.
