Description

Technical Field

[0001] The utility model relates to the technical field of wall switches, in particular to a wall switch which is easy to assemble. Background Art

[0002] A wall switch consists of a panel, a keypad, a switch element, a main frame, a rear steel plate, and other components. By pressing the keypad, the rocker inside the switch element rotates, thereby connecting or disconnecting the circuit. The connection structure of traditional wall switches is often a snap-on connection, which also causes the connection structure to be easily damaged and cracked during the disassembly and assembly process of the wall switch, seriously affecting the structural strength between components and posing certain electrical hazards. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a wall switch that is easy to assemble, including a panel, a keypad, a switch member, a main frame and a rear steel plate. The panel is mounted on the main frame, and the panel is clamped to the main frame. The switch member is provided with a terminal for an external power supply and a rocker for controlling the on and off of the circuit. The rocker is clamped with a keypad located in the center of the panel. The switch member is provided with a clamping portion distributed in a circle, and the main frame is provided with a mounting portion corresponding to the clamping portion. The switch member is rotatably clamped to the main frame through the mounting portion, and the rear steel plate is clamped to the switch member. The back of the main frame is provided with a first support bar for preventing the switch member from rotating and opening, and the first support bar abuts against the four sides of the rear steel plate.

[0004] By adopting the above technical solution, during installation, the switch piece is rotatably installed on the main frame through the clamping portion, the rear steel plate is clamped to the switch piece, and the rear steel plate is embedded between the main frame and the switch piece, so that the rear steel plate completely fixes the switch piece and the main frame, thereby simplifying the installation method and making it easy to disassemble and assemble the switch piece for easy maintenance.

[0005] The utility model is further configured such that the clamping portion is provided with a first protrusion and a step surface, the mounting portion is provided with a first arc groove for passing through the first protrusion, and a second arc groove for clamping the first protrusion, and the mounting portion is clamped between the first protrusion and the step surface.

[0006] Furthermore, the first arc groove and the second arc groove are concentrically distributed, and the radius of the first arc groove is greater than the radius of the second arc groove.

[0007] By adopting the above technical solution, during installation, the clamping parts at the four corners of the switch member pass through the mounting part through the first arc groove, and the switch member is rotated until the second arc groove is clamped between the first protrusion and the step surface, thereby completing the preliminary fixation of the switch member and the main frame. The installation method is simple and convenient. Compared with the traditional clamping structure, the first protrusion of the clamping part can be thickened to improve the connection strength between the switch member and the main frame, avoid the switch member from detaching from the main frame, affect the stability of the subsequent line structure, and improve the safety of users' electricity use.

[0008] The utility model is further configured such that second protrusions for clamping the rear steel plate and U-shaped grooves are provided on both sides of the switch member, and the second protrusions are provided with inclined surfaces for guiding the installation of the rear steel plate, and the rear steel plate is clamped between the second protrusions and the main frame.

[0009] By adopting the above technical solution, when the rear steel plate is installed, the second protrusion will undergo a small elastic deformation, so that the rear steel plate is clamped between the second protrusion and the main frame. The cross-section of the second protrusion is trapezoidal, thereby increasing the contact area between the second protrusion and the rear steel plate, and improving the structural strength of the connection between the switch component and the rear steel plate. When the switch component needs to be disassembled, press the second protrusion to remove the rear steel plate first, and then rotate to remove the switch component. The disassembly method is convenient.

[0010] The present invention is further configured such that screw seats are provided on both sides of the switch member, the rear steel plate is provided with a bent portion abutting against the screw seats, and the bent portion is provided with a mounting hole for mounting to a socket bottom box.

[0011] By adopting the above technical solution, when the utility model is installed on the wall, the screws are sequentially passed through the screw seat and the mounting hole threadedly connected to the socket base box. The structural strength of the screw seat is improved by the bent portion to avoid deformation and cracking of the screw seat when the screw is driven.

[0012] The utility model is further configured such that the main frame is provided with a card slot and an anti-return block, the panel is provided with a card member adapted to the card slot, and a receiving groove corresponding to the anti-return block, and the panel is provided with a second support bar distributed in a rectangular shape, and the panel is abutted against the outer side surface of the main frame through the second support bar.

[0013] By adopting the above technical solution, the second support bar uses a point-to-surface method instead of a surface-to-surface method to reduce the contact area between the main frame and the panel, facilitate the disassembly and assembly of the panel, and prevent the panel from being reversed by the anti-reverse block, thereby improving assembly efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The switch piece is rotatably mounted on the main frame through the clamping part, and the rear steel plate is clamped to the switch piece and embedded between the main frame and the switch piece. The rear steel plate completely fixes the switch piece and the main frame, thereby simplifying the installation method, making the switch piece easy to install and disassemble, improving production efficiency and facilitating maintenance;

[0016] 2. Compared with the traditional clip-on structure, the first protrusion of the clip-on part can be thickened to improve the connection strength between the switch and the main frame, avoid the switch from being separated from the main frame, and affect the stability of the subsequent circuit structure, thereby improving the safety of users' electricity use.

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
