Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a metal buckle and a metal nameplate. Background Technology

[0002] In daily production, materials such as clothing, leather goods, packaging tools, car carpets, and car seat covers need to be fitted with metal labels, nameplates, or irregularly shaped plates to facilitate consumers and staff to understand the brand information of the products. At the same time, the metal labels also serve a decorative purpose.

[0003] The existing methods for installing metal signs mainly include the following two: one is to install one or more sheet-like pins made of iron or other metal materials on the back of the metal sign, and then use a perforated metal plate as a base plate, insert the pins into the holes of the metal plate and bend them so that the metal sign is stuck on the base plate; the other is to attach one or more cylindrical rods to the back of the metal sign, and then use rivet caps to press and assemble it on the material.

[0004] Due to the complex shapes of irregularly shaped signs, the two assembly methods mentioned above are primarily manual in actual manufacturing. Positioning holes must be drilled in the materials to be assembled, and then the signs must be aligned manually before being pressed or hammered together. This traditional process is inefficient, involves numerous steps, and is prone to errors during production, damaging materials and sign components, resulting in significant material damage during assembly. Furthermore, if the assembly position is incorrect, rework is difficult, increasing product costs and hindering standardized, automated, and mechanized production. Utility Model Content

[0005] The purpose of this utility model is to provide a metal buckle and a metal nameplate, which aims to solve the problems of traditional metal nameplate assembly processes causing significant material damage, difficulty in rework and correction, and inability to standardize, automate and mechanize production.

[0006] To achieve the above objectives, according to a first aspect of this utility model, this utility model provides a metal buckle, including a socket and a cap. The socket is provided with three or more sets of prongs, which are evenly distributed on the outside of the socket. The ends of the prongs are provided with piercing portions, the included angle of which is ∠1, 60°≤∠1≤100°, and the piercing portions are used to pierce materials. The cap is used to bend the prongs. The cap includes a bending portion, a rotating portion, and a locking portion. A locking cavity is provided in the cap, and the bending portion, rotating portion, and locking portion are all provided in the locking cavity. The bending portion is located at the center of the locking cavity, the rotating portion is connected to the bending portion, and the locking portion is connected to the rotating portion. The bending portion is used to bend the prongs, the rotating portion is used to bend the bent prongs in the opposite direction, and the locking portion is used to lock the bent prongs.

[0007] Furthermore, the pins are in the shape of an inwardly concave arc, with a radius of R1 of 3.5mm ≤ R1 ≤ 4.5mm, a pin width of W1 of 2.5mm ≤ W1 ≤ 3.5mm, a pin height of H1 of 7mm ≤ H1 ≤ 9mm, and a pin thickness of D1 of 0.6mm ≤ D1 ≤ 0.8mm.

[0008] Furthermore, the socket has three prongs.

[0009] Furthermore, the socket is equipped with a limit hole.

[0010] Furthermore, both the bending and locking parts of the cap are inwardly concave arc shapes. The radius of the bending part is R3, 13mm≤R3≤16mm, and the radius of the locking part is R4, 4.5mm≤R4≤6mm. The rotating part is composed of tangent straight segments and arc segments. The straight segments of the rotating part are connected to the bending part, and the arc segments of the rotating part are tangent to the locking part and have the same opening direction.

[0011] Furthermore, a circular opening is provided in the locking cavity away from the bending part, and the diameter of the opening is larger than the diameter of the socket.

[0012] Furthermore, the cap is circular with a radius of R2, 7mm≤R2≤8mm; the height of the cap is H2, 5.5mm≤H2≤6.5mm; the distance between the bottom of the bend and the opening is H3, 1.5mm≤H3≤2.5mm; and the wall thickness of the cap is D2, 0.25mm≤D2≤6mm.

[0013] According to a second aspect of the present invention, a metal sign includes a metal sign body and the aforementioned metal buckle, wherein at least one metal buckle is provided on the metal sign body.

[0014] This utility model provides a metal buckle and metal nameplate. Compared with the prior art, the sharp piercing part can easily pierce the material. Relying on the piercing action of the piercing part, there is no need to pre-drill holes in the material before fixing the metal nameplate. After the prongs are bent, they can lock the locking cavity of the cap, fixing the cap and the socket together, thus locking the metal nameplate and the material together. Through the structural design of the metal buckle of this utility model, standardized, automated and mechanized assembly of metal nameplates can be achieved. Compared with manual assembly, production efficiency is increased by more than three times, production costs are reduced, and processing efficiency is effectively improved. Since the material is not pre-drilled, the piercing area of ​​the prongs is small, which can effectively protect the surface of the material. Therefore, if an assembly error occurs, rework can be carried out, and the second rework will not affect the quality and appearance of the product. When rework is required, the worker applies a large pulling force to the cap, and the locking part applies a reverse force to the bent prongs, causing the bent prongs to straighten again. The prongs can then be removed from the opening, and the metal nameplate can be reassembled. Attached Figure Description

[0024] The present invention will be described in detail below with reference to specific embodiments.

[0025] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0026] like Figures 1 to 6As shown, according to a first aspect of the present invention, the present invention provides a metal buckle, including a socket 2 and a cap 1. The socket 2 is provided with three or more sets of prongs 20, which are evenly distributed on the outside of the socket 2. The ends of the prongs 20 are provided with piercing portions 21, the included angle of the piercing portions 21 being ∠1, 60°≤∠1≤100°, and the piercing portions 21 are used to pierce materials. The cap 1 is used to bend the prongs 20, and the cap 1 includes a bending portion 10 and a rotating portion 10. The cap 1 has a locking cavity 14, and the bending part 10, the rotating part 11, and the locking part 12 are all located in the locking cavity 14. The bending part 10 is located at the center of the locking cavity 14, the rotating part 11 is connected to the bending part 10, and the locking part 12 is connected to the rotating part 11. The bending part 10 is used to bend the pin 20, the rotating part 11 is used to bend the bent pin 20 in the opposite direction, and the locking part 12 is used to lock the bent pin 20.

[0027] With the above design, the piercing part 21 is set as a pointed structure. Under the action of the piercing part 21, the pin 20 can easily pierce the material. After the pin 20 passes through the material and enters the locking cavity 14, it will contact the bending part 10. Under the action of continuous pressure, the bending part 10 forces the pin 20 to bend outward. After continuing to apply pressure to the cap 1, the piercing part 21 of the pin 20 touches the rotating part 11. Under the action of the rotating part 11, the bent pin 20 changes direction for the second time until it abuts the locking part 12. The deformed pin 20 changes from a vertical shape to a hook shape, and the hook part can just fit into the locking part 12 to ensure that the metal plate can be locked on the material. The structural design of this metal buckle, because the material is not pre-drilled, results in a small piercing area for the pin 20, effectively protecting the material's surface. Therefore, rework is possible in case of assembly errors, and the second rework does not affect the product's quality or appearance. When rework is required, the worker applies a large pulling force to the cap 1, and the locking part 12 applies a reverse force to the bent pin 20, straightening it back into place. The pin 20 can then be removed from the opening 13 (described later), and the metal nameplate can be reassembled. This design enables standardized, automated, and mechanized assembly of metal nameplates, increasing production efficiency by more than three times compared to manual assembly, reducing production costs, and effectively improving processing efficiency.

[0028] In this embodiment, the pin 20 is generally in the shape of an inwardly concave arc, with a radius of R1 of 3.5mm≤R1≤4.5mm, a width of W1 of 2.5mm≤W1≤3.5mm, a height of H1 of 7mm≤H1≤9mm, and a thickness of D1 of 0.6mm≤D1≤0.8mm.

[0029] Through the above design scheme, the pin 20 with a thickness D1 of 0.1-0.5mm can be easily bent, and the arc-shaped pin 20 can also increase the structural strength, so that the bent pin 20 has a higher locking strength, preventing the cap 1 from being accidentally touched and falling off during subsequent use; setting the height H1 to 7-9mm can prevent the pin 20 from being too long and affecting the bending effect, and can also prevent the pin 20 from being too short and unable to be bent in place, thus affecting the locking strength.

[0030] In this embodiment, the socket 2 is provided with three pins 20. The three pins 20 can provide a more even force distribution point, while also saving the materials required to produce the socket 2 and the pins 20.

[0031] In this embodiment, the socket 2 is provided with a limiting hole 22, which can easily fix the socket 2 to the metal nameplate and facilitate assembly.

[0032] In this embodiment, both the bent portion 10 and the locking portion 12 of the cap 1 are inwardly concave arc shapes. The radius of the bent portion 10 is R3, 13mm≤R3≤16mm, and the radius of the locking portion 12 is R4, 4.5mm≤R4≤6mm. The rotating portion 11 is composed of tangent straight line segments and arc segments. The straight line segments of the rotating portion 11 are connected to the bent portion 10, and the arc segments of the rotating portion 11 are tangent to the locking portion 12 and have the same opening direction.

[0033] In this embodiment, a circular opening 13 is provided in the locking cavity 14 away from the bending part 10, and the diameter of the opening 13 is larger than the diameter of the socket 2.

[0034] In this embodiment, the cap 1 is annular, the radius of the outermost ring of the cap 1 is R2, 7mm≤R2≤8mm; the height of the cap 1 is H2, 5.5mm≤H2≤6.5mm; the distance between the bottom of the bent part 10 and the opening 13 is H3, 1.5mm≤H3≤2.5mm; the wall thickness of the cap 1 is D2, 0.25mm≤D2≤6mm.

[0035] Through the above design scheme, the arc-shaped bending part 10 can actively guide the pin 20 to shift outward. Since there is a certain distance between the opening 13 and the bottom end of the bending part 10, even if the pressing angle is deviated, as long as the pin 20 enters the locking cavity 14 through the opening 13 and is pressed, the pin 20 will be bent by the bending part 10. The annular cap 1 can make multiple sets of pins 20 expand outward evenly, ensuring that the bent pins 20 can apply sufficient pressure to the locking part 12.

[0036] In this embodiment, the socket 2 has a simple structure. It only requires punching out the socket 2 with the pins 20 on the edge of the thin plate, and then bending the pins 20 by 90° with a mold to form the socket 2. The limiting hole 22 in the socket 2 can be used for positioning in automated processing. During automated assembly, the assembly equipment can use the limiting hole 22 to position the pins 21 toward the material. Then the assembly equipment clamps the cap 1 and makes the opening 13 face the pins 20. The cap 1 is gradually pressed down to apply pressure to the material so that the piercing part 21 pierces the material. As the cap 1 continues to be pressed down, the pins 20 bend and deform to lock the cap 1, thus completing the assembly operation.

[0037] According to a second aspect of this utility model, a metal sign includes a metal sign body and the aforementioned metal buckle, wherein at least one metal buckle is provided on the metal sign body. The at least one metal buckle is provided to accommodate metal signs of different sizes, shapes, and fixing requirements.

[0038] When installing metal nameplates, there is no need to drill positioning holes in the material. The socket 2 can be placed directly on the clamping device, and the opening 13 of the cap 1 is aligned with the pin 20 and pressed down. The piercing part 21 of the pin 20 pierces the material and enters the locking cavity 14. The vertical pin 20 bends along the edge of the bending part 10, and then bends in the opposite direction under the action of the rotating part 11. The bent pin 20 can abut against the locking part 12, so that the pin 20 is locked in the locking cavity 14 to complete the locking work. When rework is required, the worker applies a large pulling force to the cap 1, and the locking part 12 applies a reverse force to the bent pin 20, so that the bent pin 20 straightens again, making it easy to remove the pin 20 from the opening 13. Since the pin 20 is small in size, even if it pierces the material, the opening left is smaller, which can reduce the consumption required for rework.

[0039] This invention relates to a metal buckle and metal nameplate. The buckle's structural design, due to the absence of pre-drilled holes in the material and the small piercing area of ​​the prongs 20, effectively protects the material's surface. Therefore, rework is possible in case of assembly errors, and the second rework does not affect the product's quality or appearance. When rework is required, the worker applies a large pulling force to the cap 1, and the locking part 12 applies a reverse force to the bent prongs 20, straightening them. The prongs 20 can then be removed from the opening 13 (described later), and the metal nameplate can be reassembled. This enables standardized, automated, and mechanized assembly of metal nameplates, increasing production efficiency by more than three times compared to manual assembly, reducing production costs, and effectively improving processing efficiency.

[0040] Where there is no conflict, the above embodiments and features can be combined with each other.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
