[0002] The power plug is a key component for connecting electrical equipment to the power supply. The power transmission is achieved through the connection between the plug and the socket. It is widely used in various scenarios such as homes, offices, hospitals, and industries to provide a stable power supply for electrical equipment. With the development of modern technology, the application of power plugs in smart homes, mobile device charging and other fields is becoming more and more widespread, and it is also an indispensable part in medical facilities. Existing power plugs usually consist of pins, insulating shells and internal connecting wires. When the plug is inserted into the socket, the pins contact the conductive parts of the socket to form a circuit, allowing the current to flow smoothly.

[0025] Specifically, when the plug needs to be inserted into the power socket quickly and accurately, the limit plate 11 will rotate by turning the knob 12, and the limit plate 11 will drive the plug plate 8 to slide inside the turntable 7 through the limit rod 10. At the same time, the spring 2 9 will be compressed in this process, so that the pin 3 and the push rod 13 can slide smoothly inside the shell 1, and then after being aligned to the power slot by the guide rail 2, the button 14 is pressed to drive the pin 3 to slide directly into the power slot. At the same time, the rebound of the spring 2 9 acts on the plug plate 8, causing it to slide into the inside of the push rod 13 and fix the pin 3. This not only improves the insertion speed and accuracy of the plug, but also ensures that the plug can be quickly and safely inserted into the power socket, thereby improving the overall convenience of use and user experience.

[0026] Reference Figure 1 , Figure 2 and Figure 5 The outer wall of the housing 1 is fixedly connected with a fixing plate 15, and the outer wall of the fixing plate 15 is fixedly connected with a positioning rod 16; the internal thread of the fixing plate 15 is connected with a fixing bolt 17, and the outer wall of the fixing bolt 17 is fixedly connected with a knob 18; the outer wall of the fixing plate 15 is fixedly connected with a sleeve 19, and the outer wall of the fixing bolt 17 is rotatably connected to the inside of the sleeve 19; the outer wall of the fixing bolt 17 is fixedly connected with a connecting ring 20, and the outer wall of the connecting ring 20 is rotatably connected with a push plate 21, and the outer wall of the fixing bolt 17 is rotatably connected to the inside of the push plate 21; a spring 22 is arranged inside the sleeve 19, one end of the spring 22 is fixedly connected to the inside of the sleeve 19, and the other end of the spring 22 is fixedly connected to the outer wall of the push plate 21;

[0027] Specifically, when it is necessary to ensure a firm connection between the plug and the power supply, the positioning rod 16 is used to accurately position the fixing plate 15. Once the fixing plate 15 is in the correct position, the knob 2 18 is turned to drive the fixing bolt 17 to rotate between the fixing plate 15 and the sleeve 19, thereby securely fixing the fixing plate 15 on the power supply board. At the same time, the rotation of the fixing bolt 17 will also cause the connecting ring 20 to push the push plate 21. When the push plate 21 is pushed, the spring 3 22 will be compressed, and the elastic force of the spring 3 22 will push the push plate 21 back, thereby strengthening the connection between the fixing bolt 17 and the power supply slot. This not only enhances the connecting force of the fixing bolt 17, but also improves the stability of the plug, thereby ensuring that a firm connection is always maintained between the plug and the power supply.

[0028] Working principle: When the plug needs to be inserted into the power supply, the limit plate 11 is rotated by turning the knob 12, so that the limit plate 11 can cooperate with the limit rod 10 to drive the plug plate 8 to slide inside the turntable 7, and at the same time, the spring 2 9 is compressed, so that the pin 3 can slide together with the push rod 13 inside the shell 1, thereby reducing the holes that need to be aligned, and then the guide rail 2 is aligned with the power supply, so that each pin 3 can be aligned with the power slot, and then the button 14 is pushed, so that the pin 3 can be directly inserted into the inside of the power slot, and at the same time, the spring 2 9 rebounds the plug plate 8, so that the plug plate 8 can slide into the inside of the push rod 13, and then the pin 3 is fixed, so as to facilitate the plug to be quickly inserted into the power supply. The effect of the seat improves the convenience of the plug. When it is necessary to strengthen the connection between the plug and the power supply, the position of the fixing plate 15 can be positioned by the positioning rod 16, and at the same time, the knob 21 is turned to drive the fixing bolt 17 to rotate inside the fixing plate 15 and the sleeve 19, thereby fixing the fixing plate 15 on the power supply board. At the same time, the fixing bolt 17 will also drive the connecting ring 20 to push the push plate 21, so that the push plate 21 will compress the spring three 22, and the spring three 22 will also push the push plate 21 back by the elastic force, thereby strengthening the connection between the fixing bolt 17 and the power supply slot, thereby achieving the effect of firmly fixing the plug, improving the stability of the plug, and ensuring the stable connection between the plug and the power supply.
