[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model provides the following technical solution:

[0022] As attached Figure 1-3 As shown, this utility model discloses a high-strength base box, including a base box body 1 and a middle plate 2. The base box body 1 has a box body portion 3 and a middle plate connecting portion 4. The middle plate 2 is disposed within the middle plate connecting portion 4 to form a wrapping structure. Mounting holes 5 are provided on the middle plate connecting portion 4, and the mounting holes 5 penetrate the middle plate connecting portion 4 and the middle plate 2 within the middle plate connecting portion 4. Specifically, in this design, the middle plate 2 is made of stainless steel, and the base box is made of plastic. The middle plate 2 and the middle plate connecting portion 4 of the base box are integrally molded by injection molding to form a plastic-coated steel structure, so that the stainless steel middle plate 2 is wrapped by the middle plate connecting portion 4 of the base box body 1. This structure enhances the overall strength and stability of the base box without affecting the insulation performance of the base box body 1. Furthermore, the mounting holes 5 facilitate the fixing and installation of the base box, allowing it to be firmly installed in the desired location. The mounting holes 5 are located at the four corners of the middle plate 2, making it easy to fix the base box to a wall or other mounting surface using screws or other fasteners.

[0023] Furthermore, the plastic-coated steel structure has a metal layer 6 formed on the middle plate 2 and a plastic layer 7 on the middle plate connecting portions 4 located on both sides of the middle plate 2. The plastic layer 7 includes an outer plastic layer 8 on the side of the metal layer 6 away from the box body 3 and an inner plastic layer 9 on the side of the metal layer 6 closer to the box body 3. The mounting hole 5 has a large-diameter portion 10 formed on the outer plastic layer 8 and two small-diameter portions 11 formed on the metal layer 6 and the inner plastic layer 9. Specifically, in this embodiment, the large-diameter portion 10 is formed on the outer plastic layer 8, so that during the installation of the bottom box, the screw extends through the large-diameter portion 10 and then passes through the small-diameter portions 11 on the metal layer 6 and the inner plastic layer 9 in sequence before extending into the wall for fixing. At this time, the screw nut can be embedded in the large-diameter portion 10 and flush with the end face of the middle plate connecting portion 4 on the side away from the box body 3. In this way, when installing the switch panel, there will be no interference with the switch panel, thereby avoiding the problem of affecting the pressing feel of the switch panel.

[0024] Furthermore, the inner diameters of the two smaller diameter portions 11 are the same, while the nominal inner diameter of the larger diameter portion 10 is larger than the inner diameters of the two smaller diameter portions 11. Specifically, in this embodiment, the nominal inner diameter of the larger diameter portion 10 is designed to be slightly larger than the outer diameter of the screw nut to ensure that the nut can be smoothly inserted into the larger diameter portion 10. Meanwhile, the inner diameter of the smaller diameter portion 11 matches the outer diameter of the screw shank to ensure that the screw can pass tightly and securely through the smaller diameter portion 11 and extend into the wall. This design not only ensures the robustness of the base box installation but also optimizes the convenience and aesthetics of the installation process.

[0025] Furthermore, a screw is provided on the middle plate connecting part 4. The screw has a shank and a nut. The shank passes through the outer plastic layer 8, the metal layer 6, and the inner plastic layer 9 in sequence. The nut is embedded in the large-diameter portion 10 of the mounting hole 5 located on the outer plastic layer 8. Specifically, in this embodiment, the nut of the screw is designed to fit tightly with the large-diameter portion 10 of the mounting hole 5 to ensure that the screw will not loosen or fall off during installation. When the screw is tightened, the nut will fit tightly against the inner wall of the large-diameter portion 10, while the shank passes through the metal layer 6 and the inner plastic layer 9, penetrating deep into the wall, thereby providing strong fixing force. In addition, since the nut is embedded in the large-diameter portion 10, the nut will not interfere with the switch panel when it is installed, thus ensuring smooth operation and a good appearance of the switch panel.

[0026] Furthermore, the outer plastic layer 8 has a chamfered structure 12 near the edge of the large diameter portion 10 of the mounting hole 5. Specifically, in this embodiment, the chamfered structure 12 helps guide the screw to smoothly enter the mounting hole 5 during installation, avoiding difficulties in screw installation or damage to the screw caused by the edge of the mounting hole 5 being too sharp.

[0027] Furthermore, a reinforcing rib 13 protrudes from the side of the middle plate 2 away from the box body 3, and a groove corresponding to the shape of the reinforcing rib 13 is formed on the side of the middle plate 2 near the box body 3. Specifically, in this embodiment, the inclusion of the reinforcing rib 13 significantly improves the bending strength and load-bearing capacity of the middle plate 2, making the bottom box more stable when subjected to external forces. Simultaneously, the groove corresponding to the shape of the reinforcing rib 13 formed on the side of the middle plate 2 near the box body 3 reduces the overall weight of the bottom box.

[0028] Furthermore, the middle plate 2 has junction box mounting holes 18, and the two sides of the center of the middle plate 2 are recessed to form grooves 15. The junction box mounting holes 18 are located in the center of the grooves 15. The middle plate connecting part 4 is provided with an outer groove 16 corresponding to the grooves 15 and a middle plate hole 17 corresponding to the junction box mounting holes 18. Specifically, in this embodiment, the design of the junction box mounting holes 18 facilitates the installation and fixing of the junction box, making wiring work more convenient. At the same time, the recesses formed on both sides of the center of the middle plate 2 and the corresponding middle plate holes 17 provide more stable support and positioning for the junction box, avoiding shaking or misalignment of the junction box during installation. This design not only improves the practicality of the base box but also ensures the safety and reliability of wiring work.

[0029] Reference Appendix Figure 2 A switch socket is provided, comprising the aforementioned high-strength base box. Specifically, in this embodiment, the switch socket is designed using this high-strength base box, thus possessing advantages in high strength, stability, and insulation performance. By using the high-strength base box as the supporting structure of the switch socket, the stability and safety of the switch socket during installation and use are ensured. Simultaneously, the plastic-coated steel structure design of the high-strength base box allows the switch socket to maintain a lightweight design while possessing excellent load-bearing capacity, effectively extending the service life of the switch socket.

[0030] Reference Appendix Figure 1 A wall switch is disclosed, wherein the switch socket includes the aforementioned high-strength base box. Specifically, in this embodiment, the wall switch design also utilizes this high-strength base box, thereby achieving high strength, stability, and insulation performance during installation and use. The plastic-coated steel structure of the high-strength base box not only enhances the load-bearing capacity of the wall switch but also ensures its stability and safety in various environments. Furthermore, by employing this high-strength base box, the wall switch simplifies the installation process, reduces installation costs, and improves installation efficiency.
