The frame panel has grooves on both sides, and the grooves have screw holes for fixing. The grooves also have decorative covers that match them.

[0004] The aforementioned patent uses a decorative cover to cover the fixing screws, making the screw ends not exposed and aesthetically pleasing. However, it has the following technical defects: the decorative cover is inserted into the groove and is easily loosened due to vibration, causing the fixing screws to be exposed. When the exposed screws are accidentally touched, there may be a risk of electric shock. Utility Model Content

[0005] To prevent electric shock from accidental contact with fasteners, this application provides an anti-electric shock structure and a switch socket.

[0006] Firstly, the anti-electric shock structure provided in this application adopts the following technical solution: An anti-electric shock structure includes a mounting plate, mounting holes at both ends of the mounting plate, and fasteners passing through the mounting holes. Both ends of the mounting plate are equipped with protective covers for covering the mounting holes. One end of the protective cover is hinged to the mounting plate, and the other end is connected to a fastener. The mounting plate has a mounting groove for receiving the protective cover, and the inner wall of the mounting groove is connected to a positioning part for the fastener to hook onto.

[0007] By adopting the above technical solution, firstly, it can prevent the protective cover from becoming loose due to vibration, so that the protective cover can effectively shield the fasteners, thereby effectively avoiding the risk of electric shock caused by accidental contact with the fasteners and improving safety; secondly, it makes the installation and removal of the protective cover more flexible, and facilitates the installation, inspection and maintenance of the fasteners.

[0008] Optionally, the bottom wall of the mounting groove is provided with a sealing groove, and the inner wall of the sealing groove is connected with a sealing ring that is fixedly connected to the protective cover.

[0009] By adopting the above technical solution, a good sealing effect can be formed between the protective cover and the mounting groove, effectively preventing dust, moisture and other impurities from entering the mounting groove, and further reducing problems such as rust and short circuits caused by moisture or dust covering the fasteners.

[0010] Optionally, the protective cover has a prying ramp on the lower side of one end near the fastener, and a prying groove is provided on one side of the prying ramp, which is located on one side of the mounting plate.

[0011] By adopting the above technical solution and setting the pry groove, the contact area between the user's fingers or tools and the prying slope can be increased, which makes it easier to separate the buckle from the positioning part and improves the convenience of operation.

[0012] Optionally, one end of the protective cover is fixedly connected to two hinge blocks, and the inner walls of the opposite sides of the mounting groove are fixedly connected to hinge rods that are connected to the hinge blocks.

[0013] By adopting the above technical solution, the cooperation between the hinge block and the hinge rod can ensure the firmness and reliability of the connection between the protective cover and the mounting groove, and enable the protective cover to rotate smoothly.

[0014] Optionally, each of the two hinge rods has an inlet ramp on an adjacent side, and each of the two hinge blocks has an installation port on an opposite side that mates with the inlet ramp.

[0015] By adopting the above technical solution, the installation process of the protective cover can be simplified and the installation difficulty reduced by introducing the inclined surface and the installation port design.

[0016] Optionally, the mounting groove is provided with a limiting surface on the side opposite to the positioning part to limit the rotation angle of the protective cover.

[0017] By adopting the above technical solution, the setting of the limiting surface can limit the rotation angle of the protective cover, which can not only prevent the protective cover from rotating excessively and affecting its function of covering the fastener, but also prevent the fastener from being disassembled or installed due to accidental rotation of the protective cover.

[0018] Optionally, the positioning part is provided with a guide slope on the side near the protective cover, and the hook part of the buckle is provided with an installation slope that cooperates with the guide slope on the side near the mounting groove.

[0019] By adopting the above technical solution, and by setting the installation slope and guide slope, the accuracy and convenience of the connection between the fastener and the positioning part can be guaranteed.

[0020] Optionally, the fastener has a disassembly ramp on the side opposite to the mounting ramp.

[0021] By adopting the above technical solution, by moving the protective cover, the disassembly ramp of the buckle is moved to slide at one end of the positioning part, so that the buckle can be stably disengaged from the positioning part, preventing the buckle from getting stuck when it is separated from the positioning part.

[0022] Secondly, the switch and socket provided in this application adopts the following technical solution: A switch socket includes the aforementioned anti-electric shock structure; it also includes a panel mounted on one side of a mounting plate, the panel covering the mounting groove.

[0023] By adopting the above technical solution, users can conveniently control the power on and off of the socket through the control switch. At the same time, the anti-electric shock structure effectively avoids the risk of electric shock caused by accidental contact with fasteners, thus better meeting users' needs for safe electricity use.

[0024] In summary, this application has the following beneficial effects: 1. This application can effectively shield the fasteners with the protective cover, preventing the protective cover from becoming loose due to vibration, and can stably cover the mounting hole, thereby effectively avoiding the risk of electric shock caused by accidental contact with the fasteners.

[0025] 2. This application simplifies the installation process of the protective cover and reduces the installation difficulty by using the hinge block and hinge rod, as well as the design of the guide slope and the installation port. Furthermore, the cooperation between the snap fastener and the positioning part ensures the stability of the connection between the protective cover and the mounting plate.

[0026] 3. By disassembling the inclined surface, prying the inclined surface, and setting the pry groove, the protective cover can be easily disengaged from the positioning part when it needs to be opened, improving the convenience of maintenance and repair. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0030] This application discloses a switch socket with an anti-electric shock structure. In this application embodiment, the switch socket is a wall socket with a switch. In other embodiments, the switch socket can also be a wall switch or a wall socket. The anti-electric shock structure is applicable to various switches or sockets.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The switch and socket include an anti-electric shock structure, which comprises a mounting plate 1, mounting holes 2 at both ends of the mounting plate 1, and fasteners 3 passing through the mounting holes 2. A panel 11 covers one side of the mounting plate 1, and the panel 11 covers the mounting holes 2. A wiring unit is provided on the side of the mounting plate 1 opposite to the panel 11. The panel 11 is used to cover the mounting plate 1 and improve the installation and aesthetics of the wall switch. The mounting plate 1 is provided with a socket for inserting a power plug. A control switch for controlling the power supply to and from the socket is provided on one side of the socket.

[0032] Reference Figure 2 , Figure 3 The mounting plate 1 has protective covers 5 at both ends to cover the mounting holes 2. The mounting plate 1 has mounting grooves 4 for receiving the protective covers 5, and the mounting grooves 4 communicate with the mounting holes 2. The protective covers 5 are used to cover the mounting grooves 4 to prevent the fasteners 3 from being directly exposed.

[0033] Reference Figure 2 , Figure 3 and Figure 4Two hinge blocks 51 are fixedly connected to one end of the protective cover 5. Hinges 41, connected to the hinge blocks 51, are fixedly connected to the inner walls of opposite sides of the mounting groove 4, allowing the protective cover 5 to rotate along the hinges 41 within the mounting groove 4. A through hole is provided in the middle of the hinge block 51 for inserting the hinge 41. In this application, the hinge block 51 is connected to the protective cover 5, and the hinge 41 is connected to the inner wall of the mounting groove 4. In other embodiments, the hinge 41 can be fixed to both ends of the protective cover 5, and the mounting plate 1 has grooves for inserting the hinge 41, thus connecting the protective cover 5 to the mounting plate 1.

[0034] Reference Figure 2 , Figure 3 and Figure 4 Each of the two hinge rods 41 has an inlet ramp 411 on one side adjacent to the other, and each of the two hinge blocks 51 has an installation port 511 on the opposite side that mates with the inlet ramp 411, which is used to assist the hinge block 51 in quickly connecting to the hinge rod 41.

[0035] When installing the protective cover 5, move the protective cover 5 so that the mounting openings 511 on the lower side of the two hinge blocks 51 contact the guide slope 411 of the hinge rod 41 respectively. Then press the protective cover 5 to drive the inner wall of the mounting opening 511 to slide along the guide slope 411. At this time, one end of the two hinge blocks 51 retracts until the hinge rod 41 is inserted into the through hole of the hinge block 51, thus completing the installation of the protective cover 5.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The mounting groove 4 has a limiting surface 42 on the side near the hinge rod 41 to limit the rotation angle of the protective cover 5. When the protective cover 5 is rotated and contacts the limiting surface 42, the protective cover 5 is opened to the maximum angle to prevent the rotation of the protective cover 5 from affecting the disassembly or installation of the fastener 3.

[0037] Reference Figure 2 , Figure 3 and Figure 8 The bottom wall of the mounting groove 4 is provided with a sealing groove 44 that communicates with the mounting hole 2. A sealing ring 53 is fixedly connected to one side of the protective cover 5 and is connected to the inner side of the sealing groove 44. When the protective cover 5 is in the closed state, the outer wall of the sealing ring 53 is connected to the inner wall of the sealing groove 44 and covers the outside of the fastener 3, which can prevent dust, moisture and other impurities from entering the interior of the sealing groove 44 when the protective cover 5 is in the closed state, thereby improving the service life of the fastener 3.

[0038] Reference Figure 5 , Figure 6 and Figure 7A latching member 6 is fixedly connected to one end of the protective cover 5 away from the hinge block 51. A positioning part 7 for the latching member 6 to hook onto is fixedly connected to the mounting plate 1, and the positioning part 7 is disposed in the mounting groove 4. An installation slope 61 is provided on the side of the hook of the latching member 6 near the mounting groove, and a guide slope 71 that cooperates with the installation slope 61 is provided on the side of the positioning part 7 near the protective cover 5. A disassembly slope 62 is provided on the side of the hook of the latching member 6 away from the installation slope 61. When the latching member 6 disengages from the positioning part 7, the disassembly slope 62 slides at one end of the positioning part 7.

[0039] When in use, press the protective cover 5 to bring the mounting slope 61 of the buckle 6 into contact with the guide slope 71 until the buckle 6 is engaged in the positioning part 7, thus closing the protective cover 5; by moving one end of the protective cover 5, the disassembly slope 62 is moved along the corner of the positioning part 7. At this time, the buckle 6 retracts again towards the fastener 3 until the mounting slope 61 is completely disengaged from the corner of the positioning part 7, thus opening the protective cover 5.

[0040] Reference Figure 5 , Figure 6 and Figure 7 The protective cover 5 has a prying ramp 52 at one end near the latch 6. A prying groove 43 is provided on one side of the prying ramp 52, located on the inner wall of the mounting groove 4 and directly below the prying ramp 52, to increase the operating space for moving the protective cover 5. In use, a tool is inserted into the prying groove 43, one end of the tool is placed against one side of the prying ramp 52, and the protective cover 5 is pried outwards until the latch 6 is removed from the positioning part 7, thus opening the protective cover 5.

[0041] The implementation principle of this application embodiment is as follows: Before installation, open the protective cover 5 until it contacts the limiting surface 42. At this point, rotate the protective cover 5 to its maximum angle to expose the mounting hole 2. Then tighten the fastener 3 until the switch socket is fixed. Next, rotate the protective cover 5 again until the buckle 6 is engaged with the positioning part 7 to close the protective cover 5. Finally, install the panel 11 on the outside of the mounting plate 1 to complete the installation of the switch socket.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
