Description

Technical Field

[0001] The utility model relates to a wall switch and a socket, in particular to an installation protection structure, a wall switch and a wall socket. Background Art

[0002] A switch is an electronic component that can open a circuit, interrupt the current, or cause it to flow to another circuit. As people's quality of life requirements continue to improve, the requirements for product operating experience, and as the number of household appliances continues to increase, the demand and application of wall switches are becoming more and more extensive, especially the demand for wall switches. A "wall switch" refers to an electrical switch installed on the wall, used to connect and disconnect the circuit, and control the switch of the lighting. In a narrow sense, electrical products usually only refer to switches and sockets in building electrical systems. They usually include a switch base, internal functional parts, buttons or jacks. The internal functional parts are installed on the switch base, and the circuit is turned on or off by pressing the button. Existing wall switches usually include a mounting frame, a dark box and an internal functional module. The dark box is installed in the wall. The internal functional module is set on the base and then fixed to the bottom box through the mounting frame. Usually, a panel is also set on the mounting frame. Depending on the internal functional components and the panel, it can be divided into a plug-in board or a switch.

[0003] In actual use, the mounting bracket protrudes from the wall. Existing mounting brackets are typically over 10mm thick, affecting the overall aesthetic. Therefore, existing "wall switches" typically have the mounting bracket thinned, creating "thin-wall switches," typically reducing the thickness to around 6mm. However, during installation, since the mounting bracket is secured to the concealed cassette with screws, installers often use an electric screwdriver to tighten the screws until they stop. This can easily deform the thin wall of the "thin-wall switch" during installation, rendering the product inoperable. Therefore, existing thin-wall switches typically use metal brackets, enclose a metal bracket within a standard plastic component (PC), or utilize a PC and fiberglass composite material (the mounting bracket of standard switches is formed from a single-piece PC material) as the mounting bracket to prevent deformation during installation. This increases the cost of the mounting bracket and complicates the process. Utility Model Content

[0004] In order to solve the problem in the background art that the mounting frame of the existing wall switch and socket is easily deformed during installation, the utility model provides an installation protection structure, a wall switch, and a wall socket.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] Depend on Figure 1 Combine Figure 2-5 As shown, a mounting protection structure includes:

[0027] Mounting screw 1, for connection;

[0028] The support sleeve 2 is provided with a tearing portion 21 for facilitating opening so as to separate the support sleeve 2 radially;

[0029] The adjustment block 3 is mounted on the support sleeve 2. The mounting screw 1 passes through the adjustment block 3 and the support sleeve 2. The mounting screw 1 drives the adjustment block 3 to move axially, causing the adjustment block 3 to break the tear portion 21 of the support sleeve 2, thereby causing the support sleeve 2 to be expanded in the diameter direction of the end adjacent to the adjustment block 3. The beneficial effect of the present invention is that the support sleeve and adjustment block are provided. During the rotation of the mounting screw, the adjustment block can be driven to move axially to break the support sleeve, thereby acting as a buffer when the mounting screw is tightened, reducing pressure on the mounting plate and preventing deformation of the mounting plate that affects product performance. The present invention also has the advantages of simple structure, easy assembly, reliable operation, and long service life.

[0030] The guide groove 22 on the support sleeve 2 is arranged above the tearing portion 21. The adjusting block 3 is provided with a pressing block 31. The pressing block 31 is inserted into the guide groove 22 and presses the tearing portion 21 when driven by the mounting screw 1, thereby causing the support sleeve 2 to be stretched in the diameter direction of one end close to the adjusting block 3. Specifically, the pressing block 31 is arranged in a conical or triangular shape. The arrangement of the pressing block can easily and quickly destroy the tearing portion, so that the upper part of the support sleeve (see attached Figure 2 ) are separated, and the support sleeve provides a buffering effect, reducing the pressure on the mounting plate when tightening the mounting screws to prevent the mounting plate from deforming. Specifically, the top pressure block is conical or triangular.

[0031] The outer surface and / or inner surface of the tearing portion 21 is recessed to form a notch 23, and the notch 23 is V-shaped. This structure reduces the strength of the tearing portion, making it easier for the pressing block to press and break the tearing portion, thereby facilitating the adjustment block to break the tearing portion when the mounting screw is tightened.

[0032] The adjustment block 3 is provided with a hook 32, which is inserted into the support sleeve 2 and engaged with the support sleeve 2. The adjustment block 3 is provided with a guide bevel 33. The adjustment block 3 cooperates with the support sleeve 2 through the hook 32 and the guide bevel 33 to achieve vertical position limiting of the adjustment block 3. Specifically, the hook can cooperate with the clamping hole, clamping groove, or protrusion on the support sleeve to achieve position limiting of the adjustment block, preventing the adjustment block from falling from above. The guide bevel can cooperate with the end, bevel, or step of the support sleeve to prevent the adjustment block from falling downward. In fact, the guide bevel can also facilitate the support sleeve to be opened and also play a role in destroying the tear portion. Such a structure can make the support sleeve and the adjustment block an integrated structure before installation, which is convenient for handling and installation. When the installation screw is turned, the adjustment block can quickly and conveniently move axially to destroy the tear portion.

[0033] There are at least two support sleeves 2, and different support sleeves 2 are connected together along their axial direction to form a first state as a whole and separated to form independent support sleeves 2 in a second state. The tearing portion 21 is arranged in a straight line. Specifically, the different support sleeves 2 are connected by plugging, sleeve connection, or snap connection, and the tearing portions 21 of different support sleeves 2 are on the same straight line. Specifically, there are two support sleeves 2, and of course, three or four support sleeves 2 can also be connected to form a whole by plugging at the ends. The two support sleeves 2 have a first state of being connected together for use and a second state of being separated to form two independent support sleeves. Of course, in actual production, different support sleeves can be quickly and conveniently assembled and disassembled by plugging or snapping. In this way, one or two support sleeves can be selected based on the depth of the dark box (mounting seat) in the wall and the position of the mounting plate. The support sleeves can be easily broken off, making the selection convenient, making the product adaptable to a wide range of applications.

[0034] The inner wall of the adjustment block 3 is provided with a stopper 34, which abuts against the outer surface of the mounting screw 1. The stopper can limit the mounting screw. This structure allows the adjustment block and the mounting screw to form an integrated structure before installation, making it easier to handle and install. Generally speaking, the stopper can be triangular in shape, which can provide greater resistance and facilitate a reliable connection between the adjustment block and the mounting screw. Of course, the stopper can also be set to a semi-arc shape.

[0035] A wall switch includes a mounting plate 4, a dark box 5, a panel, and a mounting protective structure. The mounting plate 4 is fixed to the dark box 5 by mounting screws 1, and a control button is provided on the panel. Specifically, a wall socket includes a mounting plate 4, a dark box 5, a panel, and a mounting protective structure. The mounting plate 4 is fixed to the dark box 5 by mounting screws 1, and a jack is provided on the panel. The structures of the wall switch and the wall socket are basically the same at the installation site. Usually, the dark box can be set inside the wall. Taking the wall switch as an example, the dark box is set inside the wall, and the mounting plate is its frame. Internal functional parts are set on the frame as needed. A panel can be set on the frame, and a switch button is set on the panel. If the internal functional parts are adjusted and a jack is set on the panel, it can be used as a wall socket. Of course, a jack and a switch button can also be set on the panel.
