DETAILED DESCRIPTION

[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0023] Figure 1 This is a schematic diagram of the structure of the anti-forced plug-in safety socket in the embodiment of the utility model. Figure 1 ; Figure 2 This is a schematic diagram of the structure of the anti-forced plug-in safety socket in the embodiment of the utility model. Figure 2 .

[0024] like Figure 1 and Figure 2 As shown, the anti-forced plugging and unplugging safety socket provided by the utility model includes a shell 10, a socket body 20 and a limiting structure 30. A storage compartment 40 is provided in the shell 10. The socket body 20 can be movably arranged in the shell 10 and is located below the storage compartment 40. After the charging head is inserted into the socket body 20, the socket body 20 can drive the charging head to move and store the charging head in the storage compartment 40. The limiting structure 30 is arranged on the shell 10 and is located below the socket body 20. The limiting structure 30 can lock the socket body 20, thereby preventing the socket body 20 from moving, thereby improving reliability and effectively preventing forced plugging and unplugging of the charging head.

[0025] The socket body 20 includes a socket shell 21 and a socket panel 22. The socket panel 22 is arranged on the socket shell 21. Reset structures 23 are arranged on both sides of the socket shell 21. A socket hole 221 is arranged on the socket panel 22. The charging head is inserted into the socket hole 221 to turn on the power.

[0026] The reset structure 23 includes a rotating disk 231, a fixed shaft 232 and a reset spring 233. The rotating disk 231 is arranged on the socket housing 21. The rotating disk 231 is provided with a through hole 234 adapted to the fixed shaft 232. One end of the fixed shaft 232 is arranged on the housing 10, and the other end is movably inserted into the through hole 234. Two rotating disks 231 are respectively arranged on both sides of the socket housing 21. Two fixed shafts 232 are arranged on the housing 10, which are respectively located on both sides of the socket housing 21, so that the socket housing 10 can be turned around the fixed shaft 232 in the housing 10, thereby driving the charging head on the socket panel 22 to turn over. The reset spring 233 is sleeved on the fixed shaft 232. One end of the reset spring 233 is fixedly connected to the fixed shaft 232, and the other end of the reset spring 233 is connected to the rotating disk 231. When the socket housing 21 is turned over, the reset spring 233 is twisted to rebound the socket housing 10, thereby improving the reliability of the structure.

[0027] The socket housing 21 is provided with a paddle 211 , which is located below the socket panel 22 , and can be easily grasped and turned over the socket housing 21 , thereby improving reliability and practicality.

[0028] The limiting structure 30 includes an electric permanent magnetic base 31, a limiting spring 32 and a limiting plate 33. The electric permanent magnetic base 31 is arranged at the bottom of the housing 10 and is located below the socket housing 21. One end of the limiting spring 32 is connected to the electric permanent magnetic base 31, and the other end of the limiting spring 32 is connected to the limiting plate 33. The limiting plate 33 is provided with a limiting protrusion 331. The limiting plate 33 is a magnetic iron plate. When the electric permanent magnetic base 31 is powered on, it will attract the limiting plate 33, thereby driving the limiting plate 33 to move downward and compressing the limiting spring 32; when the electric permanent magnetic base 31 is powered off, the limiting plate 33 rebounds under the action of the limiting spring 32.

[0029] The socket housing 21 is cylindrical, and the socket panel 22 is arranged on the outer peripheral surface of the socket housing 21. A notch 212 is provided on the side of the socket housing 21 away from the socket panel 22. When the socket housing 21 is flipped over to drive the charging head to be stored in the storage compartment 40, the electric permanent magnetic base 31 is powered off, and the limiting plate 33 rebounds and rises, and the limiting protrusion 331 abuts against the edge of the notch 212, thereby abutting against the socket housing 21, limiting the socket housing 21, locking the charging head in the storage compartment 40, isolating the charging head, effectively preventing forced plugging and unplugging of the charging head, and improving structural reliability.

[0030] The limit structure 30 also includes a magnetic control switch 34, which is arranged on the housing 10. Two magnetic control switches 34 are located on both sides of the socket housing 21. The socket housing 21 is provided with endpoints 213 adapted to the magnetic control switch 34. The two endpoints 213 are respectively arranged on both sides of the socket housing 21, and are located on both sides of the notch 212. When the socket housing 21 is flipped upward, the magnetic control switch 34 is connected to the endpoint 213 to connect the entire circuit; when the socket housing 21 is flipped downward, the magnetic control switch 34 is disconnected from the endpoint 213, so that the socket panel 22 disconnects the circuit, thereby partially powering off the socket housing 21, further protecting the socket housing 21 from power failure, and further improving the reliability of the circuit structure.

[0031] The storage compartment 40 includes a compartment housing 41, a compartment door 42, a push plate 43, and a push spring 44. The compartment door 42 is rotatably arranged on the compartment housing 41 through a hinge. Two compartment doors 42 are arranged on the compartment housing 41. When the socket housing 21 is turned over, the socket housing 21 drives the charging head to squeeze open the compartment door 42 and enter the compartment housing 41, so that the charging head is stored in the compartment housing 41. One side of the push plate 43 is movably connected to the compartment door 42 by a hinge, and the other side of the push plate 43 is connected to the push spring 44. The end of the push spring 44 away from the push plate 43 is connected to the housing 10. When the charging head squeezes open the compartment door 42 and enters the compartment housing 41, the push plate 43 compresses the push spring 44, so that the push spring 44 is in a compressed state, and the charging head can be pushed out of the compartment housing 41 when the limiting structure 30 cancels the limit, thereby improving the structural reliability.

[0032] Figure 3 It is a structural schematic diagram of a plug ejection assembly in an embodiment of the utility model.

[0033] like Figure 3 As shown, the socket panel 22 is also provided with a plug ejection assembly 50, which includes a ejection block 51, a first connecting rod 52 and a second connecting rod 53. The socket panel 22 is provided with an ejection groove 222 adapted to the ejection block, the ejection block 51 is adapted to the ejection groove 222, and the ejection block 51 is slidably arranged in the ejection groove 222. One end of the first connecting rod 52 is rotatably connected to the fixed shaft 232 by a hinge, and the other end of the first connecting rod 52 is rotatably connected to one end of the second connecting rod 53 by a hinge, and the other end of the second connecting rod 53 is connected to the ejection block 51, so that a crank slider structure is formed between the ejection block 51, the first connecting rod 52 and the second connecting rod 53. When the socket housing 21 is flipped and drives the charging head into the dark compartment housing 41, the ejection block 51 shrinks in the ejection groove 222; when the charging head leaves the dark compartment housing 41, the ejection block 51 is pushed out from the ejection groove 222, thereby pushing the charging head away and separating it from the socket panel 22 to prevent overcharging.

[0034] The housing 10 is provided with a connection seat 11, and a wiring hole 12 is provided on the connection seat 11. The wiring hole 12 can be used to arrange the wires. The wires are connected to the socket panel 22 through the wiring hole 12 and the notch 212, so as to charge the charging head. The housing 10 is also provided with a fixing protrusion 13, and a fixing hole 14 is provided on the fixing protrusion 13. The fixing protrusion 13 is distributed at the corner of the housing 10. Screws can be inserted into the fixing block 14 to fix the housing 10, so as to facilitate the installation of the anti-forced plug-in safety socket provided by the utility model.

[0035] During use of the anti-forced plug-in safety socket provided by the utility model, the charging head is inserted into the socket hole 221 of the socket panel 22, and the socket shell 21 is rotated by the paddle 211. The socket shell 21 flips and drives the charging head to flip upward, and the charging head squeezes open the dark grid door 42 and enters the dark grid shell 41. The electric permanent magnet base 31 and the magnetic control switch 34 are powered off, the limit protrusion 331 abuts against the edge of the notch 212, and the magnetic control switch 34 is stuck in the end point 213, thereby locking the socket shell 21 and storing the charging head in the dark grid shell 41, effectively preventing the charging head from being forced to be plugged in and out. When charging is finished, the permanent magnet base 31 and the magnetic control switch 34 are energized, the limit plate 33 descends, the limit protrusion 331 separates from the edge of the notch 212, the magnetic control switch 34 separates from the end point 213, the push spring 44 and the reset spring 233 rebound, driving the socket housing 21 to flip, pushing the charging head out of the dark compartment housing 41, and the push block 51 is pushed out from the push groove 222, thereby pushing the charging head away and separating it from the socket panel 22 to prevent overcharging. Therefore, the anti-forced plug-in safety socket provided by the utility model can prevent forced plug-in and plug-out of the charging head, can prevent overcharging, and has high safety.
