Description

Buckle structure and buckle subassembly

Technical Field

The present invention relates to a buckle structure and a buckle assembly, and more particularly, to a buckle structure and a buckle assembly with dual buckle heads.

Background

Electronic components inside electronic devices on the market are mostly fixed on the casing through a quick-assembly-disassembly structure. The fast dismounting structure is formed by matching a gourd hole on the electronic element with a buckle element fixed on the casing, so that the electronic element is rapidly fixed on the casing in a buckle mode when being installed.

For the structure of the fastening element riveted on the casing by riveting, the current fastening element is designed with a single riveting part and a single fastening part, if two fastening elements are respectively arranged on two opposite sides of the same position of the plate body and two fastening parts capable of being matched with the gourd hole are arranged on two sides of the plate body, the thickness of the plate body must be increased, and the plate body has enough thickness for riveting the two riveting parts of the two fastening elements. However, the thickness of the plate body can reduce the space in the electronic device where the electronic component can be disposed, so that the difficulty of disposing the electronic component in the housing is increased. In addition, because the current snap-fit components are designed with a single riveting part and a single buckling part, if the buckling parts are arranged on the two opposite sides of the plate body, two times of riveting operation are needed, so that the time for riveting the snap-fit components is prolonged, and the cost is increased.

Disclosure of Invention

The invention provides a buckle structure and a buckle assembly, so as to solve the problem that the thickness, riveting time and cost of a plate body are increased due to the arrangement of a double-end buckle head in the prior art.

The invention discloses a buckle structure which is suitable for a plate body. The buckle structure comprises a riveting seat and two buckle heads. The riveting seat is used for riveting on the plate body, and the riveting seat has two relative terminal surfaces, and two terminal surfaces are located the both sides of plate body respectively. Two buckle heads are respectively connected with two end faces of the riveting seat.

Another embodiment of the present invention discloses a fastening assembly, which includes a plate and a plurality of fastening structures. The plate body is provided with a first surface and a second surface which are opposite. The plurality of buckle structures respectively comprise a riveting seat and two buckle heads. The riveting seat is used for riveting on the plate body, and the riveting seat has two relative terminal surfaces, and two terminal surfaces are located the both sides of plate body respectively. The two buckle heads are respectively connected to the two end faces of the riveting part and located on two opposite sides of the plate body, and the two buckle heads respectively protrude out of the first surface and the second surface of the plate body.

According to the buckle structure and the buckle assembly disclosed by the embodiment, the two buckle heads are respectively connected with the two opposite sides of the single riveting seat, so that the two buckle heads can be positioned on the two opposite sides of the plate body to form the double-headed buckle structure only by riveting the single riveting seat on the plate body. Therefore, the single riveting seat can avoid increasing the thickness of the plate body, and can also reduce the riveting times, so that the riveting cost and time can be reduced.

The above description of the present invention and the following description of the embodiments are provided to illustrate and explain the spirit and principles of the present invention and to provide further explanation of the invention as claimed in the appended claims.

Detailed Description

Please refer to fig. 1 and fig. 2. Fig. 1 is a perspective view of a buckle assembly according to a first embodiment of the present invention. Fig. 2 is a cross-sectional view of fig. 1.

The fastening assembly 10 of the present embodiment includes a plate 100, a plurality of fastening structures 200, and a retaining ring 300. The board 100 has a first surface 110 and a second surface 120 opposite to each other.

In the present embodiment, one of the fastening structures 200 is used for illustration, and each fastening structure 200 includes a rivet seat 210 and two fastening heads 220. The clinch mount 210 has two end faces 213. In detail, the rivet seat 210 includes two connecting posts 211 and a mounting plate 212. The two connecting posts 211 are connected to two opposite sides of the embedded plate 212, and the two end surfaces 213 are respectively located at one side of the two connecting posts 211 away from the embedded plate 212. In the present embodiment, the embedded plate 212 has a hexagonal shape, and the embedded plate 212 has a central axis S passing through the central points P of the two connecting posts 211. The length L1 of the insertion plate 212 in the direction perpendicular to the center axis S is greater than the length L2 of the two connection posts 211 in the direction perpendicular to the center axis S.

One of the connecting posts 211 has an outer annular surface 211a, an engagement groove 211b and an annular groove 211c, the engagement groove 211b and the annular groove 211c are formed by being recessed from the outer annular surface 211a, and the engagement groove 211b is located between the annular groove 211c and the insertion plate 212. The engaging recess 211b and the embedded plate 212 are riveted to the board body 100, such that the two connecting posts 211 at least partially protrude from the first surface 110 and the second surface 120 of the board body 100, respectively, and the annular fastening groove 211c is coplanar with the first surface 110 near a surface 2111c of the embedded plate 212.

Each of the two fastening heads 220 includes a supporting arm 221 and a fastening portion 222 connected to each other. The ends of the two supporting arms 221 away from the two retaining portions 222 are respectively connected to the two end surfaces 213, so that the two retaining heads 220 are located at two opposite sides of the board body 100 and protrude from the first surface 110 and the second surface 120 of the board body 100. The central axis S of the insertion plate 212 passes through the support arm 221 and the catch 222, and the length L4 of the catch 222 in the direction perpendicular to the central axis S is greater than the length L3 of the support arm 221 in the direction perpendicular to the central axis S.

In the present embodiment, the fastening structure 200 is an integrally formed structure, that is, the single rivet seat 210 and the two fastening heads 220 are integrally connected, but not limited thereto. In other embodiments, the rivet seat may be connected to the two snap heads by welding or the like.

The retaining ring 300 has an annular body 310 and three flanges 320, the annular body 310 has an inner edge 311, the three flanges 320 respectively protrude from the inner edge 311, the retaining ring 300 is fastened in the annular fastening groove 211c, so that the three flanges 320 are located in the annular fastening groove 211c, and the retaining ring 300 abuts against the first surface 110 of the board 100, so as to enhance the strength of the fastening structure 200 fixed on the board 100.

In the present embodiment, the retaining ring 300 has three flanges 320, which is not intended to limit the present invention. In other embodiments, the number of the flanges of the retaining ring may be less than or greater than three, or the retaining ring may be provided without any flanges, and instead the annular body of the retaining ring is directly fastened to the annular fastening groove.

Next, a process of riveting the fastening structure 200 to the plate 100 in the embodiment is described. Referring to fig. 3 and 4 together, fig. 3 is a schematic diagram illustrating a riveting process of the snap structure of fig. 1. Fig. 4 is a cross-sectional view of the snap structure of fig. 1 riveted to a plate body.

As shown in fig. 3 and fig. 4, the board body 100 of the present embodiment further has a riveting hole 130, and the fastening structure 200 passes through the riveting hole 130 in the direction D1, so that the embedding plate 212 of the riveting base 210 abuts against the second surface 120 of the board body 100. Then, a riveting tool, such as a riveting gun, applies a force to the embedding plate 212 in the direction D1, so that the embedding plate 212 is embedded in the board 100, and the board 100 is shaped and embedded in the embedding groove 211b, so that the snap structure 200 is fixed to the board 100.

Next, referring to fig. 5, fig. 5 is a schematic diagram illustrating a buckling process of the buckle of fig. 1.

As shown in fig. 5, the fastening structure 200 of the present embodiment is fixed to the plate body 100 by riveting, and the fastening ring 300 also enhances the strength of fixing the fastening structure 200 to the plate body 100. In detail, in the riveted snap structure 200, the surface 2111c of the annular buckle groove 211c adjacent to the embedded plate 212 is coplanar with the first surface 110 of the board body 100, and the snap ring 300 can be buckled in the annular buckle groove 211c from the direction D2, so that the snap ring 300 abuts against the first surface 110 of the board body 100. For example, when an electronic component is fastened to the fastening head 220 on one side of the second surface 120 of the board body 100, the retaining ring 300 abuts against the first surface 110 of the board body 100 to effectively resist the weight of the electronic component. As such, the strength of the fastening structure 200 fixed to the board body 100 is increased.

According to the buckle structure and the buckle assembly in the embodiment, the two buckle heads are respectively connected with the two opposite sides of the single riveting seat, so that the two buckle heads can be positioned on the two opposite sides of the plate body to form the double-headed buckle structure only by riveting the single riveting seat on the plate body. Therefore, the single riveting seat can avoid increasing the thickness of the plate body, and can also reduce the riveting times, so that the riveting cost and time can be reduced.

In addition, the retaining ring is buckled in the annular buckling groove and is abutted against the first surface of the plate body, so that the weight of the buckling structure applied to the buckling head of the electronic element buckled on one side of the second surface of the plate body can be effectively resisted, and the strength of the buckling structure fixed on the plate body is increased.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
