Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically to a concealed electrical device. Background Technology

[0002] Existing sockets and switches are generally installed on the wall and need to be combined with junction boxes, support frames, panels and other structures to form a complete whole. With the diversification of interior design elements and concepts, there are often special requirements for the installation position, shape and so on of sockets and switches. Therefore, it is necessary to design a concealed electrical device that is suitable for installing sockets and switches on materials such as slabs and tabletops and meets aesthetic requirements. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a concealed electrical device that is simple in structure, easy to install, and aesthetically pleasing.

[0004] To address the above problems, the following technical solution is provided: A concealed electrical device includes a nail-free bracket with a central mounting opening. The front of the nail-free bracket has a centering edge located outside the mounting opening, and the inner side of the centering edge has a fixing hole. It also includes an electrical component, which includes a fixing panel and a wiring module located on the back of the fixing panel. The fixing panel is located on the front of the nail-free bracket, and the wiring module is located inside the mounting opening. The fixing panel has adjustment holes corresponding to the fixing holes. Fixing screws pass through the adjustment holes and engage with the fixing holes or nuts corresponding to the fixing holes to fix the fixing panel to the nail-free bracket. There are two or more fixing holes, adjustment holes, and fixing screws, spaced apart along the circumferential direction of the centering edge. The front of the fixing panel has a decorative panel. The electrical component is a switch and / or a socket.

[0005] The present invention is further configured such that the outer contour of the centering edge is not greater than the outer contour of the fixed panel; when the fixing screw is fixed, the back of the fixed panel abuts against the end face of the centering edge, or a washer is fitted on the fixing screw between the back of the fixed panel and the fixing hole to control the distance between the fixed panel and the nail-free bracket.

[0006] The present invention is further configured such that the distance between the fixed panel and the nail-free bracket can be adjusted by increasing or decreasing the number of the washers and / or compressing the axial dimension.

[0007] The present invention is further configured such that, when the washer is made of elastic material, its middle section outer wall in the axial direction is provided with an outer groove and / or its two ends are provided with a chamfered surface.

[0008] The present invention is further configured such that the fixing hole is located on the centering stop or on the nail-free bracket located between the inner side of the centering stop and the outer side of the mounting opening.

[0009] The present invention is further configured such that the outer contour of the decorative panel is not smaller than the outer contour of the fixed panel, and the decorative panel and the fixed panel are connected by a snap fastener.

[0010] The present invention is further configured such that a claw is provided at the outer edge of the back of the decorative panel, and a slot and a tenon located in the slot along the circumferential direction of the fixed panel are provided at the outer edge of the fixed panel; after the claw enters the slot, the claw and the tenon are engaged by rotating the decorative panel.

[0011] The present invention is further configured such that the centering guard is circular, rectangular, polygonal, or composed of multiple outwardly protruding protrusions.

[0012] The present invention is further configured such that the adjustment hole is fan-shaped with the centering edge as the center.

[0013] The present invention is further configured such that both the fixed panel and the decorative panel are circular and correspond to the outer contour of the centering edge.

[0014] The beneficial effects of this utility model are:

[0015] 1. Taking installation on a slab as an example, after drilling a hole in the slab, apply nail-free adhesive to the back of the nail-free bracket and attach it to the back of the slab. Simultaneously, position the centering edge against the inner wall of the hole for positioning. Then, insert the electrical components from the front of the hole and secure them to the nail-free bracket with fixing screws. The wiring module passes through the mounting opening and protrudes from the nail-free bracket for easy wiring. The fixing holes are formed by tapping or self-tapping the fixing screws, or a nut is provided at the hole opening to accommodate the fixing screw. The nail-free bracket and the centering edge are integrally injection molded, or the nail-free bracket and the centering edge are... The centering edge is welded, or the nail-free bracket and the centering edge are cast. Since the fixed panel has adjustment holes, a decorative panel is used to conceal them and ensure overall aesthetics. Electrical components include switches and / or sockets for power control and access. Sockets can be two-hole sockets and / or three-hole sockets and / or USB charging ports. The decorative panel and / or fixed panel and / or centering edge correspond to the shape of the opening, and the decorative panel is flush with the opening to ensure overall aesthetics. Additionally, the decorative panel can be lower than the opening if needed.

[0016] 2. The outer contour of the centering edge should preferably be the same as that of the fixed panel. In cases where there is no need to adjust the height difference between the decorative panel and the opening, the back of the fixed panel can be directly abutted against the end face of the centering edge to achieve installation and fixation. In cases where the thickness of the rock slab is different and the height difference between the decorative panel and the opening needs to be adjusted according to the actual situation, it can be controlled by setting washers.

[0017] 3. The number of washers can be adjusted precisely by increasing or decreasing the quantity and / or compressing the axial dimension. Compression support is achieved by using elastic material, and the outer groove and / or the rounded surfaces at both ends can improve the axial adjustable dimension during compression.

[0018] 4. The outer contour of the fixed panel is preferably the same as that of the decorative panel; the decorative panel and the fixed panel are connected by a snap fastener for easy installation and disassembly; four sets of clips, slots and tenons are preferably provided, spaced 90 degrees apart along the circumferential direction of the fixed panel, decorative panel or opening; the two are engaged by rotation, and can be removed by rotating in the opposite direction, reducing the possibility of clip breakage during violent disassembly.

[0019] 5. Since the nail-free bracket is prone to leveling errors during installation, a fan-shaped adjustment hole is provided to facilitate circumferential angle adjustment of the electrical components relative to the nail-free bracket, thus preventing tilting after installation.
