Description

Technical Field

[0001] This utility model relates to the field of sheet metal connectors, specifically a lightweight sheet metal connector. Background Technology

[0002] A sheet metal joint refers to the specific part where two or more metal sheets are connected together in some way.

[0003] Current sheet metal connectors use traditional processing techniques, resulting in smooth surfaces at the installation interface that facilitate installation. However, a problem exists in actual use: the quality of these connectors is greatly affected by the quality of components such as the screw tapping hole. If the tapping precision of the hole is insufficient, stripping can easily occur, leading to part failure or screw loosening. In long-term vibration environments, the interface is also prone to loosening, further reducing the reliability of the connector and the service life of the sheet metal connector. This undoubtedly increases the stability of the sheet metal connector during use. Therefore, the inventor urgently needs to design a lightweight, self-healing, and self-anti-slip sheet metal connector to improve its service life. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a lightweight sheet metal connector to solve the technical problems of easy loosening and short service life of sheet metal connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight sheet metal connector, including an interface, one end of which is connected to a handle via a connecting arc, a base is installed below the handle, the surface of the base is machined with a straight groove through hole, the surface of the base is machined with a base rounding, the surface of the interface is provided with an interface seam, and the surface of the connecting arc is machined with a connecting arc chamfer.

[0006] By adopting the above technical solution, the interface is connected to the handle through an integrated structure design of the connecting arc. This structure makes the overall structure more stable, stronger in resisting impact, and extends the service life of the sheet metal interface. The connecting arc effectively disperses the stress concentration at the connection between the interface and the handle through the arc transition, avoiding the cracking problem that is prone to occur in right-angle connections, and laying the foundation for the stability and practicality of subsequent joint installation.

[0007] Furthermore, the interface surface is embossed to create microscopic grooves, arrays, and barb structures, and the interface is filled with microcapsules containing adhesive.

[0008] By adopting the above technical solution, the interface surface has a micro-barb structure through laser etching, and the microstructure of the adhesive surface containing microcapsules greatly increases the bonding area and mechanical interlocking force, significantly improving the joint strength and durability, and greatly increasing the contact area between the interface and the mating sheet metal parts, breaking the traditional connection mode that relies on a single friction force on a smooth surface.

[0009] Furthermore, the connecting arc surface is arc-shaped and the surface is smooth and burr-free, and the arc surface is rounded without any sharp edges.

[0010] By adopting the above technical solution, the surface of the connecting arc is processed into an arc state, which can significantly improve the bending and fracture resistance of the joint by making the stress excessively or evenly distributed, extending the service life of the joint. In addition, the surface of the connecting arc is processed smoothly without burrs, avoiding the risk of personnel being scratched by burrs and improving the safety of use.

[0011] Furthermore, the grip surface is machined to be smooth and burr-free for the operator's grip during installation.

[0012] By adopting the above technical solution, the smooth and burr-free surface of the handle provides a good grip experience for the installation of the connector, avoiding hand scratches caused by surface roughness or burrs during the assembly process, and improving the safety and comfort of operation. Especially in batch assembly or operation in narrow spaces, the smooth handle can reduce operating resistance, making it easier for operators to accurately control the installation position and angle of the connector, and improving the convenience of the installation process.

[0013] Furthermore, the base surface is machined with straight groove through holes, and the two ends of the straight groove through holes are semi-circular structures.

[0014] By adopting the above technical solution, the processing of straight groove through holes directly reduces the overall weight of the joint by removing excess material, which meets the core requirements of lightweight design. It is especially suitable for fields that are sensitive to the weight of components, and can support the weight reduction and efficiency improvement of the overall equipment without sacrificing connection reliability, thereby enhancing the stability of the joint structure.

[0015] Furthermore, an interface seam is provided on the interface surface to buffer stress on the interface during installation.

[0016] By adopting the above technical solution, the interface is not a closed circle but a design that retains an interface seam, which provides flexible adjustment space for the interface during installation. When the joint is connected to the sheet metal part, the interface seam can offset the stress caused by installation size deviation, assembly error or temperature change, and prevent the interface from deforming due to rigid constraints. This effectively improves the assembly fault tolerance rate of the joint and ensures that the interface can still achieve a stable connection even in the case of slight deviation.

[0017] Furthermore, the connecting arc surface is provided with a connecting arc chamfer to enhance the stability of the overall structure and strengthen its resistance to bending.

[0018] By adopting the above technical solutions, the chamfering of the connecting arc enhances the bending resistance of the interface and facilitates cleaning and maintenance, reduces the accumulation of dust at the corners, and helps improve the corrosion resistance of the joint. The chamfering design achieves simultaneous improvement in structural strength, assembly safety and environmental resistance without increasing material usage or affecting the lightweight goal, further optimizing the overall performance of the joint.

[0019] In summary, the present invention has the following main advantages: This invention uses an embossing process on the interface surface to create microscopic grooves, arrays, and barb structures. Furthermore, the surface microstructure, using an adhesive containing microcapsules, greatly increases the bonding area and mechanical interlocking force, significantly improving the strength and durability of the sheet metal joint, greatly extending its service life, and saving costs to achieve cost reduction and efficiency improvement.

[0020] This invention enhances the bending resistance of sheet metal joints by processing the excess material into arc or chamfered shapes and ensuring a smooth, burr-free surface. This structure also improves the safety and comfort of installation, significantly increasing installation efficiency and service life. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In this embodiment: A lightweight sheet metal connector, such as Figure 1-4 As shown, the connector includes an interface 1, one end of which is connected to a handle 3 via a connecting arc 2. A base 8 is installed below the handle 3, and the surface of the base 8 is machined with a straight groove through hole 4 and a base rounding 5. An interface seam 6 is provided on the surface of the interface 1, and a connecting arc chamfer 7 is machined on the surface of the connecting arc 2. The interface 1 is connected to the handle 3 through an integrated structural design via the connecting arc 2. This structure makes the overall structure more stable, stronger in resisting impact, and extends the service life of the sheet metal interface. The connecting arc 2 effectively disperses the stress concentration at the connection between the interface 1 and the handle 3 through a rounded transition, avoiding the cracking problem that is prone to occur in right-angle connections. This lays the foundation for the stability and practicality of subsequent connector installation. At the same time, the overall sheet metal structure design takes into account the reliability of connection, lightweight and assembly adaptability, significantly improving the practical value of the connector and enhancing the competitiveness of the sheet metal connector in the connector market.

[0025] See Figure 1 The surface of Interface 1 is embossed to create microscopic grooves, arrays, and barbed structures. Interface 1 is filled with microcapsules containing adhesive. The surface of Interface 1 is laser-etched to create microscopic barbed structures. The microstructure of the adhesive surface containing microcapsules greatly increases the bonding area and mechanical interlocking force, significantly improving the joint strength and durability. It also greatly increases the contact area between the interface and the mating sheet metal parts, breaking the traditional connection mode that relies on a single friction force on a smooth surface. At the same time, the processing technology ensures production efficiency, enabling the sheet metal joint to have better connection reliability and adaptability on the basis of lightweight design.

[0026] See Figure 1 The surface of the connecting arc 2 is arc-shaped and smooth without burrs. The arc surface must be rounded and free of sharp edges. The arc-shaped surface of the connecting arc 2 can distribute stress excessively or evenly, which significantly improves the bending and fracture resistance of the joint and extends the service life of the joint. The smooth surface of the connecting arc 2 avoids the risk of personnel scratches caused by burrs, thus improving the safety of use. At the same time, the smooth surface reduces the adhesion of dust and impurities to the surface of the sheet metal joint, reduces the accumulation of corrosive substances on the surface, improves the corrosion resistance of the joint, and expands the application market of sheet metal joints.

[0027] See Figure 1The handle 3 has a smooth, burr-free surface for the operator's grip during installation. This smooth, burr-free surface provides a good grip experience for the connector installation operation, avoiding hand scratches caused by rough surfaces or burrs during assembly, thus improving the safety and comfort of operation. Especially in batch assembly or operation in confined spaces, the smooth handle reduces operating resistance, making it easier for the operator to accurately control the installation position and angle of the connector, improving the convenience of the installation process. At the same time, the structural design of the handle 3 not only takes into account the ease of operation and the compact structure, but also creates a double guarantee for the sheet metal connector.

[0028] See figure Figure 3 The base 8 has a straight groove through hole 4 machined on its surface. The two ends of the straight groove through hole are semi-circular structures. The machining of the straight groove through hole 4 directly reduces the overall weight of the joint by removing excess material, which meets the core requirements of lightweight design. It is especially suitable for fields that are sensitive to the weight of components. It can support the weight reduction and efficiency improvement of the overall equipment without sacrificing the reliability of the connection. It enhances the stability of the joint structure. At the same time, the straight groove through hole 4 structure achieves the goal of lightweight sheet metal joints, making sheet metal joints more widely applicable.

[0029] See Figure 1 , Figure 4 The interface 1 has an interface slot 6 on its surface, which is used to buffer the stress of the interface 1 during installation. The interface 1 is not a closed circle but has the interface slot 6. This design provides elastic adjustment space for the interface during installation. When the joint is mated with the sheet metal part, the interface slot 6 can offset the stress caused by installation size deviation, assembly error or temperature change, and prevent the interface from deforming due to rigid constraints. This effectively improves the assembly fault tolerance of the joint and ensures that the interface 1 can still achieve a stable connection even with slight deviations. At the same time, it solves the problem of component damage caused by stress concentration in traditional closed interfaces.

[0030] See Figure 1 , Figure 2 The surface of the connecting arc 2 is provided with a connecting arc chamfer 7 to enhance the stability of the overall structure and strengthen its bending resistance. The chamfer 7 enhances the bending resistance of the interface and facilitates cleaning and maintenance, reducing dust accumulation at the corners and improving the corrosion resistance of the joint. The design of the connecting arc chamfer achieves simultaneous improvement in structural strength, assembly safety and environmental resistance without increasing material usage or affecting the lightweight goal, further optimizing the overall performance of the joint. At the same time, the design of the connecting arc chamfer 7 eliminates sharp edges on the surface, further optimizing the comprehensive performance of the sheet metal joint.

[0031] The implementation principle of this embodiment is as follows: First, hold the handle 3 and pick up the entire sheet metal joint. Then, by forcefully rotating the handle 3, insert the interface 1 into the mounting port of the corresponding component. During the forceful rotation, the connecting arc 2 and the chamfer 7 connecting the handle 3 and the interface 1 play a stress buffering role on the structure. In addition, the interface seam 6 retained by the interface 1 can play a role in offsetting the installation size deviation. Finally, the mounting port of the other component is spliced ​​by the base rounded 5 opened under the base 8. In this way, the two components can be connected and fixed by the joint. During the operation of the two components, the joint is prone to damage and cracking. When damage occurs, the microcapsules filled inside the interface 1 release adhesive to repair in time and make the joint more secure.
