Description

A mounting bracket anti-deformation structure Technical Field

[0001] This utility model relates to a wall switch and socket, specifically to a mounting bracket anti-deformation structure. Background Technology

[0002] A switch is an electronic component that can open a circuit, interrupt current, or divert it to another circuit. With the continuous improvement of people's living standards and the increasing demands for product operation, coupled with the growing number of household appliances, the demand and application of wall switches are becoming increasingly widespread, especially for wall switches. A "wall switch" refers to an electrical switch installed on a wall, used to connect and disconnect circuits, such as those controlling lighting. In a narrower sense, electrical products usually refer only to switches and sockets in building electrical systems. A wall switch typically includes a switch base, internal functional components, and buttons or sockets. The internal functional components are mounted on the switch base, and the circuit is connected or disconnected by pressing the button. Existing wall switches usually include a mounting bracket, a recessed box, and internal functional modules. The recessed box is installed in the wall, and the internal functional modules are located on the base and then fixed to the base box by the mounting bracket. A panel is usually also installed on the mounting bracket. Depending on the internal functional components and the panel, it can be classified as a socket or a switch. In short, whether it's a wall switch or a wall socket, it usually includes a recessed box or base box and a mounting bracket. The base box or recessed box is usually embedded in the wall, and the mounting bracket is fixed to it.

[0003] In practical use, mounting brackets protrude from the wall. Existing mounting brackets are typically over 10mm thick, affecting the overall aesthetics. Therefore, existing wall switches usually have thinner mounting brackets, becoming "thin-wall switches," with the thickness typically reduced to around 6mm. However, during installation, because the mounting bracket is fixed to the junction box with screws, installers often use electric screwdrivers to rotate the screws until they cannot be turned. Therefore, the thin wall (mounting bracket) is prone to deformation during installation, affecting the position of internal functional components and causing product malfunction. Taking wall switches as an example, deformation of the mounting bracket can cause deformation of the housing, altering the distance between the metal conductive parts connected to the terminals. When the panel is pressed, the lever may not reliably conduct the circuit or the distance may be too short, posing a safety hazard. Therefore, existing thin-wall switches typically use metal parts as supports, or encase a metal frame within ordinary plastic (PC material), or use a composite material of PC and fiberglass (ordinary switch mounting brackets are made of one-piece PC material) as the mounting bracket to prevent deformation during installation. This increases the cost of the mounting bracket and makes the manufacturing process more complex. Summary of the Invention

[0004] To address the problem that existing brackets in the background art are prone to deformation during installation, leading to product failure, this utility model provides an anti-deformation structure for the mounting bracket.

[0005] The technical solution of this utility model is: a mounting bracket anti-deformation structure, including a mounting bracket, and further comprising:

[0006] A junction box is used for mounting and securing with a mounting bracket.

[0007] The fastener is provided on the dark box;

[0008] The limiting element is located on the fixing element;

[0009] The mounting screw passes through the mounting bracket, the limiting member, and the fixing member to fix the mounting bracket to the junction box. One end of the limiting member extends beyond the junction box and is flush with or protrudes from the wall. When the mounting bracket is installed, it abuts against the bottom of the mounting bracket to limit the mounting bracket.

[0010] As a further improvement of this utility model, the fixing member is provided with a connecting hole, and the limiting member and the fixing member are connected by external thread and internal thread, so that the limiting member and the fixing member can be adjusted along the axial direction of the connecting hole.

[0011] As a further improvement of this utility model, the limiting member is inserted into the communicating hole and is adjustablely matched with the fixing member along the axial direction of the communicating hole.

[0012] As a further improvement of this utility model, one end of the limiting member extends beyond the junction box and is flush with the wall, while the other end is inserted into the fixing member. One end of the limiting member is provided with a supporting flange, which is located below the mounting bracket.

[0013] As a further improvement of this utility model, the fixing member is detachably connected to the dark box.

[0014] As a further improvement of this utility model, the dark box is provided with a mounting hole, and the fixing member passes through the mounting hole and is detachably connected to the dark box through a hook.

[0015] As a further improvement of this utility model, the hook is provided with a guide portion.

[0016] As a further improvement of this utility model, it also includes a insert, which is disposed in the fixing member, and the mounting screw passes through the mounting frame and the limiting member and is threadedly connected to the insert, thereby fixing the mounting frame and the dark box.

[0017] As a further improvement of this utility model, the fixing member is L-shaped or T-shaped, and the insert is horizontally arranged.

[0018] As a further improvement of this utility model, there are two fixing members, each of which is provided with a limiting member, and the two limiting members are arranged symmetrically.

[0019] The beneficial effects of this utility model are that it incorporates a limiting component, through which the mounting screw passes. When the mounting screw secures the mounting bracket, the limiting component abuts against the bottom of the mounting bracket, thus reliably limiting the mounting bracket, preventing deformation, and avoiding any impact on product performance. This utility model also boasts advantages such as simple structure, convenient assembly, reliable operation, and long service life. Attached Figure Description

Detailed Implementation

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0027] As shown in Figure 1 and Figures 2-5, a mounting bracket anti-deformation structure includes a mounting bracket 1, and further includes:

[0028] Junction box 2 is used for mounting and fixing bracket 1;

[0029] Fixing member 3, wherein the fixing member 3 is provided on the dark box 2;

[0030] Limiting component 4 is provided on fixing component 3;

[0031] The mounting screw 5 passes through the mounting bracket 1, the limiting member 4, and connects to the fixing member 3, thereby fixing the mounting bracket 1 to the junction box 2. One end of the limiting member 4 extends beyond the junction box 2 and is flush with or protrudes from the wall 7, abutting against the bottom of the mounting bracket 1 during installation to limit its position. The beneficial effects of this invention are that the limiting member, through which the mounting screw passes, and the abutting against the bottom of the mounting bracket during screw fixing ensure reliable positioning of the mounting bracket, preventing deformation and avoiding impact on product performance. This invention also features simple structure, convenient assembly, reliable operation, and long service life.

[0032] The fixing member 3 has a connecting hole 31. The limiting member 4 and the fixing member 3 are connected by external and internal threads, allowing the limiting member 4 and the fixing member 3 to be adjusted axially along the connecting hole 31. Specifically, the limiting member 4 is inserted into the connecting hole 31 and adjusted axially with the fixing member 3 along the connecting hole 31. This allows the limiting member to be inserted into the fixing member, forming an integral structure. The distance between the limiting member and the fixing member can be adjusted, thereby adjusting the position of the end of the limiting member beyond the junction box. This allows the limiting member to limit the mounting bracket and prevent excessive deformation during the fixing of the mounting bracket screws.

[0033] One end of the limiting member 4 extends beyond the junction box 2 and is flush with the wall 7, while the other end is inserted into the fixing member 3. A supporting flange 41 is provided at one end of the limiting member 4, and the supporting flange 41 is located below the mounting bracket 1. The limiting member can slightly extend beyond the wall, but in this invention, the limiting member is flush with the wall during installation. This ensures that the wall and the outer perimeter of the mounting bracket are closely fitted and limited during installation and fixing. The connecting holes of the mounting bracket (for screws to pass through) are limited by the end of the limiting member, preventing deformation and thus avoiding excessive movement and deformation of the mounting bracket.

[0034] The fixing component 3 is detachably connected to the junction box 2. Specifically, the junction box 2 has a mounting hole 21, and the fixing component 3 passes through the mounting hole 21 and is detachably connected to the junction box 2 via a hook 32. This structure facilitates the fitting of the fixing frame and the junction box into an integrated structure, reduces the risk of component loss, facilitates assembly, and simplifies the structure. More specifically, the hook 32 has a guide part 33. The guide part facilitates disassembly and assembly, and simplifies the structure.

[0035] This utility model also includes a insert 6, which is disposed within the fixing member 3. The mounting screw 5 passes through the mounting bracket 1 and the limiting member 4 and is threadedly connected to the insert 6, thereby fixing the mounting bracket 1 to the junction box 2. More specifically, the fixing member 3 is L-shaped or T-shaped, and the insert 6 is horizontally arranged.

[0036] The insert is easy to fix, has a simple structure, and is limited by the fixing component when inserted into the fixing component (along the axis of the mounting screw). After the mounting screw is inserted, it also limits the insertion of the insert (in the insertion and withdrawal direction). This ensures that the insert is reliably limited, the insert and the mounting screw are easy to match, the structure is simple, it is easy to reliably fix the mounting bracket, and the parts are easy to replace.

[0037] There are two fixing components 3, each of which is equipped with a limiting component 4, and the two limiting components 4 are symmetrically arranged. This makes the product structure symmetrical, the force evenly distributed, and the parts compatible.
