Description

Technical Field

[0001] This utility model relates to the field of electromechanical leakage prevention technology, and in particular to an electromechanical safety leakage prevention protection device. Background Technology

[0002] Leakage current is the leakage of current caused by insulation damage or other reasons. When the casing of an appliance is connected to the live wire of the mains for some reason, a potential difference exists between the appliance and ground, resulting in leakage current. An effective method for detecting leakage current is to use a test pen to touch a suspected live object: if the neon bulb of the test pen only lights up briefly and then quickly goes out, it indicates that the live object carries static electricity; if the neon bulb continues to light up, it indicates that there is a leakage current.

[0003] Existing power plugs leave gaps between themselves and the socket after insertion. If water is accidentally splashed on them, it can easily seep into the socket's internal contact points, causing electrical leakage. Furthermore, in existing technology, the connection between the power plug and socket is easily weakened by external force, leading to leakage at the device's connection point. Therefore, this invention proposes an electromechanical safety leakage protection device to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an electromechanical safety leakage protection device. By rotating the sealing cover, the sealing cover moves on the insulating connecting ring, causing the first external thread to connect with the first internal thread. After one end of the sealing cover is connected to the sealing groove, it can seal and protect the connection between the cylindrical plug body and the socket body, and prevent the cylindrical plug body from detaching from the socket body, thus providing stable leakage protection capability.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0006] An electromechanical safety leakage protection device includes a cylindrical plug body for connection to electromechanical equipment and a socket body for connection to the cylindrical plug body.

A first external thread is provided on the outer wall of one end of the sealing cover, and a first internal thread adapted to the first external thread is provided in the sealing groove.

[0007] A further improvement is that the sealing cover includes a first insulating cover and a second insulating cover. The first insulating cover has a second insulating cover at one end. The first insulating cover is annular, and the second insulating cover is frustum-shaped. The inner diameters of the first insulating cover and the second insulating cover are the same. The first external thread is provided on the outer wall of the first insulating cover.

[0008] A further improvement is that the first insulating cover and the second insulating cover are integrally molded structures.

[0009] A further improvement is that: the outer wall of the insulating connecting ring is provided with a second external thread, and the inner walls of the first insulating cover and the second insulating cover are provided with a second internal thread. The sealing cover is movably connected to the insulating connecting ring by the cooperation of the second internal thread and the second external thread.

[0010] A further improvement is that an operating ring is provided at one end of the second insulating cover, and the outer wall of the operating ring is provided with anti-slip texture.

[0011] A further improvement is that the inner diameter of the operating ring is smaller than the inner diameter of the second insulating cover.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] Example 1

[0021] according to Figure 1-4 As shown, this embodiment proposes an electromechanical safety leakage protection device, including a cylindrical plug body 1 connected to electromechanical equipment, and a socket body 2 for connecting to the cylindrical plug body 1. An insulating connecting ring 3 is provided on the outer wall of one end of the cylindrical plug body 1, and a sealing cover 4 is provided on the outer side of the insulating connecting ring 3. The sealing cover 4 is movably connected to the insulating connecting ring 3. The socket body 2 is provided with a socket hole adapted to the metal rod of the cylindrical plug body 1. A sealing groove 5 is provided on the outer side of the socket hole. The sealing groove 5 is adapted to the sealing cover 4. A first external thread 6 is provided on the outer wall of one end of the sealing cover 4, and a first internal thread 7 adapted to the first external thread 6 is provided in the sealing groove 5.

[0022] When the electromechanical safety leakage protection device of this utility model is used, after the cylindrical plug body 1 is connected to the socket body 2, the sealing cover 4 on the outside of the insulating connecting ring 3 is rotated, so that the end of the sealing cover 4 with the first external thread 6 moves into the sealing groove 5. Then, by rotating the first external thread 6, it will connect with the first internal thread 7 after entering the sealing groove 5, thereby sealing and preventing slippage of the connection seam between the cylindrical plug body 1 and the socket body 2, and preventing water from entering the connection seam and causing leakage.

[0023] The sealing cover 4 includes a first insulating cover 401 and a second insulating cover 402. The first insulating cover 401 has the second insulating cover 402 at one end. The first insulating cover 401 and the second insulating cover 402 are integrally formed, and their inner diameters are the same. The first insulating cover 401 is annular, and the second insulating cover 402 is frustoconical. The first external thread 6 is provided on the outer wall of the first insulating cover 401. This configuration ensures that the sealing cover 4 can rotate smoothly on the insulating connecting ring 3, and the frustoconical shape of the second insulating cover 402 facilitates water drainage, allowing for rapid drainage of water droplets falling onto the second insulating cover 402.

[0024] The outer wall of the insulating connecting ring 3 is provided with a second external thread 8, and the inner walls of the first insulating cover 401 and the second insulating cover 402 are provided with a second internal thread 9. The sealing cover 4 is movably connected to the insulating connecting ring 3 by the cooperation of the second internal thread 9 and the second external thread 8. The sealing cover 4 is rotated when the insulating connecting ring 3 moves, specifically by the cooperation of the second internal thread 9 and the second external thread 8.

[0025] This invention features an insulating connecting ring 3 on the outer wall of one end of a cylindrical plug body 1, and a sealing cover 4 movably connected to the outside of the insulating connecting ring 3. A first external thread 6 is provided on the outer wall of one end of the sealing cover 4, and a first internal thread 7 is provided in the sealing groove 5 on the socket body 2. When the cylindrical plug body 1 is inserted into the socket body 2, rotating the sealing cover 4 causes it to move on the insulating connecting ring 3, connecting the first external thread 6 with the first internal thread 7. Once one end of the sealing cover 4 is connected to the sealing groove 5, it can seal and protect the connection between the cylindrical plug body 1 and the socket body 2, preventing the cylindrical plug body 1 from detaching from the socket body 2, and providing stable leakage protection.

[0026] Example 2

[0027] according to Figure 1-4 As shown, this embodiment proposes an electromechanical safety leakage protection device, including a cylindrical plug body 1 connected to electromechanical equipment, and a socket body 2 for connecting to the cylindrical plug body 1. An insulating connecting ring 3 is provided on the outer wall of one end of the cylindrical plug body 1, and a sealing cover 4 is provided on the outer side of the insulating connecting ring 3. The sealing cover 4 is movably connected to the insulating connecting ring 3. The socket body 2 is provided with a socket hole adapted to the metal rod of the cylindrical plug body 1. A sealing groove 5 is provided on the outer side of the socket hole. The sealing groove 5 is adapted to the sealing cover 4. A first external thread 6 is provided on the outer wall of one end of the sealing cover 4, and a first internal thread 7 adapted to the first external thread 6 is provided in the sealing groove 5.

[0028] The sealing cover 4 includes a first insulating cover 401 and a second insulating cover 402. The first insulating cover 401 has a second insulating cover 402 at one end. The first insulating cover 401 and the second insulating cover 402 are integrally formed structures, and the inner diameters of the first insulating cover 401 and the second insulating cover 402 are the same.

[0029] The second insulating cover 402 has an operating ring 10 at one end. The outer wall of the operating ring 10 has anti-slip texture, and the inner diameter of the operating ring 10 is smaller than the inner diameter of the second insulating cover 402. By setting the operating ring 10, the sealing cover 4 can be rotated from the operating ring 10. The anti-slip texture helps the operator to hold the sealing cover 4 stably while rotating it.

[0030] The length of the sealing cover 4 is greater than the length of the insulating connecting ring 3. This design ensures that the sealing cover 4 can stably connect the cylindrical plug body 1 and the sealing groove 5, preventing water leakage and electrical leakage, as well as preventing the cylindrical plug body 1 and the socket body 2 from becoming loose and causing electrical leakage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
