[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role that electricity plays in our lives and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. Electrical equipment needs to be connected to a socket for power supply. When the electrical equipment is turned off, it is generally disconnected from the socket to avoid wasting electricity. At this time, the socket is idle and easily contaminated by dust or impurities, and it is easy for water to enter and soak the circuit, which will cause the internal function of the socket to be damaged, and it is easy to cause dangerous situations, such as short circuits and fires, so there are safety hazards.

[0003] The prior art controls the locking of the top cover through a control module including a processor and a drive unit, so that the top cover is opened or closed above the socket, which has a good dust-proof effect. However, its control module relies on a variety of circuit components to be implemented, has a high production cost, and lacks a waterproof design. Water can easily flow into the socket along the gap in the top cover and soak the circuit, posing a safety hazard. Utility Model Content

[0029] In any one of the socket groups, a mounting groove 8 is formed on the surface of the top cover 2, the first waterproof pad 22 is located at the top of the mounting groove 8, and the second waterproof pad 7 is located at the bottom of the mounting groove 8. The first waterproof pad 22 and the second waterproof pad 7 are both made of rubber material. A mounting block 23 is fixed on the mounting groove 8, and the mounting block 23 is an inverted U-shaped structure. The inverted U-shaped opening of the mounting block 23 faces the outside of the socket body 1, and the positioning block 4 is located at the inverted U-shaped opening position of the mounting block 23. The positioning block 4 is a U-shaped structure, and the rotating plate 5 is located on one side of the U-shaped opening of the positioning block 4. The other side of the positioning block 4 forms a guiding inclined surface inclined from top to bottom toward the inner direction of the positioning block 4, and the inclination angle of the guiding inclined surface is 45 degrees. When the spring 6 is in a natural state, the guiding inclined surface of the positioning block 4 penetrates the outer wall of the socket body 1.

[0030] In any one of the socket groups, a first rotating shaft 51 is arranged between the inner walls on both sides of the mounting groove 8, the first rotating shaft 51 penetrates the mounting block 23 and the locking block 4, and is connected to the rotating plate 5, a slide groove 231 is formed on the inner walls on both sides of the mounting block 23, a protruding structure matching the slide groove 231 is formed on the outer walls on both sides of the locking block 4, the other end of the spring 6 is fixed to the mounting block 23, the locking block 4 slides in the slide groove 231, and the moving direction of the locking block 4 is limited.

[0031] In any one of the socket groups, a slot 12 is formed on the surface of the socket body 1, and the slot 12 fits with the top cover 2. The number of the top covers 2 is the same as the slot 12. The top cover 2 is arranged above the slot 12 and corresponds to the slot 12. Connecting holes are opened on the inner walls on both sides of the slot 12, and a second rotating shaft 21 is arranged between the connecting holes. The second rotating shaft 21 penetrates the top cover 2, and the top cover 2 flips and rotates relative to the socket body 1 through the second rotating shaft 21. Five sockets 11 are formed on the surface of the slot 12, and the five sockets 11 are used to connect an external plug to power the electrical equipment.

[0032] The implementation principle of Example 1 of the present application is as follows: when the socket is idle, the top cover 2 is pressed downward, so that the blocking block 4 is squeezed by the inner wall of the socket body 1 and gradually shrinks along the guiding inclined surface toward the inside of the socket body 1, and is gradually inserted into the mounting hole on the socket body 1 from the second. When the blocking block 4 is fully inserted into the mounting hole, the inner wall of the socket body 1 no longer squeezes the blocking block 4, and the spring 6 connected to the blocking block 4 automatically rebounds to lock the blocking block 4 in the mounting hole of the socket body 1. The rebound of the spring 6 also drives the pull ring 4 to tightly buckle the first waterproof pad 22. The first waterproof pad 22 elastically fills the gap at the top of the socket body 1, and cooperates with the second waterproof pad 22 at the bottom of the top cover 2 to tighten the slot inside the socket body 1. 12 is isolated and protected against water and dust; when the socket needs to supply power to an external electrical device, the pull ring 3 is pulled to make the pull ring 3 rotate relative to the top cover 2 through the first rotating shaft 51, driving the rotating plate 5 fixed with the pull ring 3 to rotate synchronously, and one end of the rotating plate 5 rotates into between two adjacent coils of the spring 6, stretching the spring 6 toward the inside of the socket body 1, and further driving the mounting block 23 connected to the spring 6 to slide along the slide groove 231 toward the inside of the socket body 1, so that the guiding slope on the mounting block 23 is retracted into the inside of the socket body 1, and at this time the top cover 2 is opened by the second rotating shaft 21, exposing the slot 12 to the outside, and the plug of the external electrical device is plugged into the jack 11 on the slot 12.
