Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to an extended socket. Background Technology

[0002] When using household appliances, the plug needs to be inserted into the socket to establish an electrical connection. Therefore, every household installs wall sockets during renovation. However, as the number of appliances in the home increases, the original wall sockets become insufficient. People can only increase the number of sockets available by plugging in extension cords into the wall sockets. However, this method, where extension cords hang from the wall and rest on the floor, can affect home cleaning and aesthetics.

[0003] In view of this, Chinese utility model patent CN223194084U discloses an expandable socket base box, including a base frame and an expansion base box for corresponding cooperation with a wall socket box. The expansion base box is fixedly connected to one side of the base frame, with its lower end flush with the lower end of the base frame and its upper end higher than the upper end of the base frame, so that the wiring function key inside the expansion socket can be built into the expansion base box. Several wire holes are opened on the end of the expansion base box facing the base frame. When installing the expansion socket, the base frame with the expansion base box is fixed to the wall socket box, so that the base of the entire expansion socket is firmly fixed to the wall. Then, the power cord inside the wall socket box is passed through the wire holes and placed inside the expansion base box, and electrically connected to the wiring function key inside the expansion base box. Thus, based on the original wall socket, an expansion socket is extended on one side of the wall socket to increase the number of sockets and meet the needs of increased electrical appliances. However, there are two problems: 1. Since the wiring hole is located on the side of the expansion box, the wiring operation is restricted, which affects the installation efficiency and increases the installation time cost; 2. The expansion box is fixed to the wall by passing the fastening screw through the second mounting hole on the fixing part, which requires drilling holes in the wall, making the installation troublesome and damaging to the wall.

[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an extension socket to address the shortcomings of the prior art, thereby solving the problems of inconvenient wiring, low installation efficiency, and the need to drill holes in the wall for fixing, which damages the wall.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an extended socket, comprising a base plate and a cover box, wherein the cover box is detachably connected to the base plate, and a bottom frame is provided on one side of the base plate for corresponding cooperation with a wall socket box, and the lower end of the cover box facing the bottom frame is provided with several openings for wiring notches facing the base plate.

[0007] The above technical solution allows for the detachable design of the cover and base plate, facilitating the installation and maintenance of internal components. At the same time, the wiring notch replaces the traditional side wiring hole, allowing the power cable to be routed through the wiring notch when installing the cover, significantly improving installation efficiency and reducing installation time.

[0008] A further provision of the above technical solution is that the bottom frame has an avoidance notch at one end near the wiring notch, which corresponds to the position of the wiring notch.

[0009] By adopting the above technical solution, the position of the avoidance gap corresponds to the wiring gap, which can prevent the power cord from protruding from the bottom frame edge, making the wiring smoother and thus avoiding interference with the installation of the original wall socket.

[0010] A further provision of the above technical solution is that: the bottom surface of the base plate is provided with an attachment groove at the end away from the bottom frame, and a plurality of attachment protrusions are evenly distributed on the bottom surface of the attachment groove.

[0011] Using the above technical solution, the groove can accommodate nail-free adhesive or double-sided tape, and the protrusion can increase the contact area between the adhesive layer and the base plate, improve the bonding firmness, and achieve the base plate to be fixed to the wall without drilling, thus avoiding damage to the integrity and aesthetics of the wall.

[0012] A further provision of the above technical solution is that: several slots are symmetrically provided on both sides of the base plate, and buckles corresponding to the slots are provided on the lower inner side wall of the cover box.

[0013] Using the above technical solution, the cooperation of the buckle and the slot enables quick assembly and disassembly of the cover and the base plate without the need for additional tools, simplifying the installation and disassembly process and facilitating the later inspection or replacement of internal components.

[0014] A further provision of the above technical solution is as follows: a first step is provided at the lower end of the inner sidewall of the lid, a second step is provided at the lower edge of the bottom plate that can abut against the first step, a plurality of outwardly extending limiting protrusions are provided on the second step, and a limiting groove is provided at the lower edge of the lid that corresponds to and cooperates with the limiting protrusions.

[0015] Using the above technical solution, the abutment of the first and second ladders can provide vertical positioning for the lid installation, preventing the lid from being installed too deep or too shallow; the cooperation of the limiting protrusion and the limiting groove can restrict the lateral movement of the lid, ensuring that the lid and the base plate are accurately positioned and structurally stable after installation, and preventing displacement during use.

[0016] A further feature of the above technical solution is that the inner edge of the bottom frame protrudes inward and is provided with two opposing mounting lugs, each mounting lug having a mounting hole, which corresponds one-to-one with the fixing hole on the wall socket box.

[0017] By using the above technical solution, the bottom frame of the base plate can be firmly fixed to the wall socket box by passing screws through the mounting holes and the fixing holes of the wall socket box, providing a stable installation base for the entire extension socket, and eliminating the need to drill additional holes in the wall, thus protecting the wall surface.

[0018] A further provision of the above technical solution is as follows: one or more socket modules are installed on the side of the base plate facing the cover box, each socket module is electrically connected to a control switch installed on the base plate, the cover box is provided with socket slots corresponding to the socket modules, and the cover box is also provided with switch clearance holes corresponding to the positions of the control switches.

[0019] By adopting the above technical solution, the socket module can provide additional sockets to meet the needs of multiple electrical appliances being used simultaneously; the control switch can individually control the power on and off of the corresponding socket module, avoiding the safety hazards caused by electrical appliances being powered on for a long time, and improving the safety and flexibility of use.

[0020] A further provision of the above technical solution is that: a circuit board is also mounted on the base plate, a USB interface and a Type-C interface are mounted on the circuit board, and the cover is provided with interface clearance holes corresponding to the USB interface and the Type-C interface respectively.

[0021] Using the above technical solutions, the USB interface and Type-C interface can meet the charging needs of digital devices such as mobile phones and tablets, expand the function of the socket, and adapt to more types of devices.

[0022] The beneficial effects achieved by this utility model are as follows: the design of detachable installation of the cover box and the base plate, and the setting of a wiring notch on the side of the cover box, makes it more convenient to thread the power cord during socket installation, improves installation efficiency, and reduces installation time; at the same time, by using nail-free adhesive or double-sided adhesive to fix the extension base plate to the wall, drilling holes in the wall is avoided, protecting the integrity and aesthetics of the wall.
