[0002] A power plug refers to a device that connects electrical appliances and other devices to a power source. The power plug is usually plugged into a socket. Sockets are installed in each room of every household, and plugs are inserted into the sockets, including plugs for connecting to a TV, plugs for connecting to a router, plugs for connecting to an air conditioner, etc.

[0003] Cats and dogs are common pets in existing families. Keeping pets can not only bring companionship and emotional support to people, but also contribute to the improvement of mental health, physical health and social interaction. At the same time, it also cultivates people's sense of responsibility and caring ability. However, cats and dogs are lively and active, and they are likely to touch the connecting wires of the plugs, causing the connection between the plug and the socket to become loose or even fall off, which requires re-plugging, which is rather troublesome. Moreover, when cats and dogs are tripped by the connecting wires on the plugs, the connecting wires pull on the plugs, making it easy for the connecting wires and the plugs to be damaged due to the pulling force.

One end of the pulling spring 221 is fixed to the inner wall of the box body 210, and the other end of the pulling spring 221 is fixed to one side of the clamping assembly 230. When the cover body 400 is disassembled, the pulling spring 221 pulls the clamping assembly 230, so that the clamping assembly 230 moves away from the connecting wire 11, canceling the clamping of the connecting wire 11, which is convenient to pull out the plug 10.

[0038] The limiting box 200 includes a clamping assembly 230 for clamping the connecting wire 11, and two clamping assemblies 230 are provided. The clamping assembly 230 includes a clamping block 231 for clamping the connecting wire 11. An anti-slip convex block 232 for anti-slip is fixedly installed on one side of the clamping block 231. A slider 233 is fixedly installed at the rear end of the clamping block 231, and the pulling spring 221 is fixedly installed on one side of the slider 233. A second limiting hole 234 for the limiting rod 220 to slide is formed in the middle of the slider 233.

[0039] The socket box 001 includes a locking assembly 300 for locking the protective cover 002. The locking assembly 300 includes a plug 310. A magnetic block a311 is fixedly installed inside the plug 310. A connecting rod 312 for limiting the plug 310 is fixedly installed at the upper end of the plug 310.

[0040] The upper end of the connecting rod 312 is fixedly installed with a limit disk 320. The front end of the limit disk 320 is fixedly installed with a lever 321 for facilitating the pulling of the limit disk 320. When the cover body 400 is installed at the front end of the box body 100, the lever 321 is in the cavity of the sliding groove 420. The rear end of the limit disk 320 is fixedly installed with a U-shaped plate 322, and the U-shaped plate 322 is used to connect the two limit disks 320. A spring 330 for pushing the limit disk 320 is sleeved on the upper end of the rod body of the connecting rod 312, and the spring 330 is in the box body of the box body 100.

[0041] A protective cover 002 for protecting the socket box 001 is installed at the front end of the socket box 001. The protective cover 002 includes a cover body 400. The rear end of the cover body 400 is installed with an elastic clamping plate 410 for sliding in the cavity of the slot 110. A clamping groove 411 for engaging with the clamping block 111 is formed in the middle of the elastic clamping plate 410. A sliding groove 420 for the lever 321 to slide is formed in the middle of the cover body 400. When assembling the cover body 400 and the box body 100, the elastic clamping plate 410 and the slot 110 are pushed, and the cover body 400 is pushed backward, so that the clamping block 111 is inserted into the cavity of the clamping groove 411 to complete the locking of the cover body 400.

[0042] A push block 430 for pushing the clamping assembly 230 to clamp the connecting wire 11 is fixedly installed below the rear end of the cover body 400. The end of the push block 430 in contact with the clamping assembly 230 is processed into an arc surface. A jack 431 for the insertion block 310 to expand and contract is formed in the upper end of the push block 430. A magnetic block b432 for attracting the magnetic block a311 is fixedly installed inside the push block 430.

[0043] After the plug 10 is inserted into the socket jack, the cover body 400 closes the box body 100. When the elastic clamping plate 410 moves toward the rear end of the cavity of the slot 110, the push block 430 synchronously moves into the box body of the limit box 200. The arc surface of the push block 430 synchronously pushes the clamping assembly 230, so that the two clamping assemblies 230 approach the connecting wire 11. Finally, the clamping assembly 230 clamps the connecting wire 11, so that when a pet cat or dog touches the connecting wire 11, it is not easy to cause the plug 10 to become loose. While the clamping assembly 230 clamps the connecting wire 11, the insertion block 310 moves to the entrance of the cavity of the jack 431. Under the attraction of the magnetic block b432 to the magnetic block a311, the insertion block 310 is inserted into the cavity of the jack 431 to further lock the cover body 400.

[0044] When disassembling the cover body 400, the lever 321 is pushed upward into the cavity of the sliding groove 420, so that the insertion block 310 moves out of the cavity of the jack 431. At the same time, the cover body 400 is tilted forward, so that the clamping block 111 moves out of the notch of the clamping groove 411, and the cover body 400 can be quickly disassembled.
