Detailed Implementation Methods

[0031] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0032] Please see Figures 1 to 8 A detachable rivet for connecting a bracket handle includes a rivet head 1 and a rivet shaft 2, the rivet shaft 2 including an extension 21 for passing through a bracket 3 and a handle 4 to connect the two, and a fastening portion 22 near one end of the rivet head 1 for interference fit with the bracket 3 to prevent the rivet shaft 2 from disengaging from the bracket 3 and the handle 4.

[0033] This application discloses a detachable rivet for connecting a bracket handle. An extension on the rivet's main shaft passes through the bracket and handle, connecting them. A fastening portion is interference-fitted with an opening on the bracket, effectively preventing the rivet's main shaft from detaching and ensuring a stable connection. This design prevents flange formation at the rivet's tail during connection, eliminating the need for hard damage. Separation is easily achieved by applying external force to the rivet's tail, simplifying disassembly and allowing for rivet reuse, thus reducing material waste and lowering production costs.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer diameter of the fastening part 22 is R, and the outer diameter of the extension part 21 is L, wherein R > L.

[0035] In this embodiment, the fastening part 22 is ensured to have a tight interference fit with the bracket 3, thereby firmly locking the rivet main rod 2 within the bracket 3 and handle 4, preventing it from loosening or detaching. When the rivet main rod 2 passes through the bracket 3 and handle 4, the smaller diameter L of the extension 21 allows it to pass smoothly through the connector, while the larger diameter R of the fastening part 22 provides the necessary fastening force, making the connection more stable. This not only simplifies the assembly process but also enhances the reliability and durability of the connection. When it is necessary to connect the bracket 3 and handle 4, the extension 21 of the rivet main rod 2 is passed through the preset holes of the two components, and then the rivet head 1 is gently tapped with a tool (such as a hammer or an automated press) to allow the rivet main rod 2 to pass through completely and for the fastening part 22 to fit tightly against the bracket 3. At this time, the interference fit between the larger diameter R of the fastening part 22 and the hole of the bracket 3 generates sufficient friction to prevent the rivet main rod 2 from retracting or rotating, thereby achieving a stable connection.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fastening part 22 is provided with a plurality of arrayed rhomboid blocks 221.

[0037] In this embodiment, after the rivet main shaft 2 passes through the bracket 3 and handle 4, the rhomboid blocks 221 on the fastening part 22 will embed into the hole wall of the bracket 3, forming a firm interlocking structure, effectively preventing the rivet main shaft 2 from rotating or loosening during the connection process. The arrangement of the rhomboid blocks 221 changes the stress distribution on the contact surface between the fastening part 22 and the bracket 3, increases the contact area, and introduces a microscopic mechanical interlocking effect. When the rivet is subjected to external force, these rhomboid blocks 221 can effectively disperse and absorb the external force, avoiding connection failure caused by stress concentration. At the same time, the array arrangement of the rhomboid blocks 221 can also guide the deformation during the assembly process, allowing the fastening part 22 to better adapt to the shape and size changes of the hole position of the bracket 3, improving the success rate and efficiency of assembly.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the rhombus block 221 is conical, and the top of the rhombus block 221 is provided with a mating surface 2211.

[0039] In this embodiment, the conical structure allows the rhombus-shaped block 221 to more smoothly embed into the hole wall of the bracket 3 during assembly, reducing assembly resistance and ensuring full contact and engagement between the rhombus-shaped block 221 and the hole wall after connection. The top contact surface 2211 further increases the contact area, improves friction and mechanical locking force, and effectively prevents the rivet main rod 2 from rotating or loosening in the connected state. When the rivet main rod 2 passes through the bracket 3 and handle 4, the conical rhombus-shaped block 221 will first contact the hole wall with its smaller bottom. As the rivet main rod 2 is pushed forward, the rhombus-shaped block 221 gradually embeds into the hole wall. Its inclined structure guides the hole wall material to undergo plastic deformation and wrap around the rhombus-shaped block 221, forming a strong mechanical interlock. The top contact surface 2211 ensures a tight fit between the rhombus-shaped block 221 and the hole wall, preventing relative sliding when subjected to vibration or external force.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the fastening part 22 is provided with a prism 222 and a pyramid 223 corresponding to the rhomboid block 221 at one end near the extension part 21, and the prism 222 and the pyramid 223 are spaced apart from each other along the circumferential direction of the rivet main rod 2.

[0041] In this embodiment, the prism 222 and pyramid 223 work in conjunction with the rhombus block 221. When the rivet shaft 2 passes through the bracket 3 and handle 4, these geometric features are embedded in the hole wall of the bracket 3, forming a complex mechanical interlocking structure that effectively prevents the rivet from loosening or rotating. The prism 222 provides a large contact area and support, enhancing the friction between the fastening part 22 and the hole wall of the bracket 3, while the tapered structure of the pyramid 223 helps guide the deformation and flow of the hole wall material, allowing the fastening part 22 to fit more tightly against the hole wall. The combination of these features not only disperses stress and prevents connection failure caused by stress concentration, but also significantly improves the strength and durability of the connection through multi-point contact and interlocking.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the rivet cap 1 and the rivet main rod 2 are integrally formed.

[0043] In this embodiment, the one-piece molding process eliminates connection defects and stress concentration points that may occur in traditional assembly processes, ensuring the overall strength and reliability of the rivet. Secondly, the one-piece molded rivet can distribute stress more evenly under load, reducing the risk of localized stress concentration and thus extending the rivet's service life. Furthermore, the one-piece molding process simplifies the production process, reduces manufacturing costs and assembly time, and improves production efficiency.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, after the rivet main rod 2 passes through the bracket 3 and the handle 4, the front end of the rivet main rod 2 protrudes outward from the outside of the bracket 3.

[0045] In this embodiment, when disassembly is required, a tool can be applied to the protruding part to provide a reverse pushing force, thereby easily removing the rivet main rod 2 from the bracket 3 and handle 4, achieving a detachable function. This design avoids the destructive operation required for traditional rivet disassembly, improving maintenance convenience and the reusability of parts.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the length of the extension 21 is D, and the length of the fastening part 22 is S, wherein D ≥ 3S.

[0047] In this embodiment, sufficient material extension space and connection stability are ensured when the rivet connects the bracket 3 and the handle 4. The longer length of the extension 21 allows sufficient material to enter and lock into the holes of the bracket 3 and the handle 4, thereby ensuring a tight and reliable connection.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the rivet cap 1 is in the shape of an inverted frustum.

[0049] In this first embodiment, as Figure 3 As shown, the frustum-shaped rivet head 1 provides a smooth striking surface, allowing the hammer or press to apply force more evenly during installation, avoiding rivet deformation or damage caused by stress concentration. Secondly, the frustum-shaped design increases the contact area of ​​the rivet head 1, enabling it to transmit force more stably to the rivet shaft 2 during striking, thus improving installation efficiency and connection reliability.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the rivet cap 1 is cylindrical.

[0051] In this second embodiment, as Figure 6 As shown, the cylindrical rivet head 1 provides a flat striking surface, allowing the hammer or press to apply force stably during installation, ensuring uniform force transmission and avoiding rivet deformation or damage caused by stress concentration.

[0052] The working principle of this embodiment is as follows:

[0053] This application discloses a detachable rivet for connecting a bracket handle. An extension on the rivet's main shaft passes through the bracket and handle, connecting them. A fastening portion is interference-fitted with an opening on the bracket, effectively preventing the rivet's main shaft from detaching and ensuring a stable connection. This design prevents flange formation at the rivet's tail during connection, eliminating the need for hard damage. Separation is easily achieved by applying external force to the rivet's tail, simplifying disassembly and allowing for rivet reuse, thus reducing material waste and lowering production costs.
