[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] With the development of science and technology, the application of electricity has become more and more popular. With the improvement of people's quality of life, people's material life has become more and more abundant, and the electrical equipment used has also been in demand more and more. Electricity has become an indispensable and important energy source in people's lives, especially at home. Various new household appliances are emerging in an endless stream, and the electrical appliances used in the home are directly plugged into the socket through the plugs that come with the appliances.

[0041] In daily life, most sockets are two-hole sockets or three-hole sockets. The two-hole sockets have a live wire socket and a neutral wire socket, and the three-hole sockets have a live wire socket, a neutral wire socket and a ground wire socket. The plug equipped with each type of electrical appliance can only be plugged into the corresponding type of socket and is not compatible, resulting in poor applicability of the electrical appliances. If the accessories do not have a corresponding type of socket, they cannot be used, causing inconvenience to users.

[0042] To solve the above problems, this embodiment provides a plug, such as Figure 1 to Figure 7As shown, the plug includes a shell 1, a first pin assembly 4 and two groups of second pin assemblies 2. The shell 1 is provided with a storage groove 14. The first pin assembly 4 includes a ground pin 41. The ground pin 41 can be switchably arranged in the shell 1 so that the ground pin 41 can be received in the storage groove 14. The second pin assembly 2 includes a rotating pin 21 and a driving member 22. The rotating pin 21 is passed through the shell 1 and can rotate relative to the shell 1. The driving member 22 is movably arranged in the shell 1. The driving member 22 is configured to drive the rotating pin 21 to rotate to change the angle between the rotating pin 21 and the corresponding socket on the socket, so that one group of second pin assemblies 2 can be plugged into the neutral socket of the socket, and the other group of second pin assemblies 2 can be plugged into the live socket of the socket.

[0043] In the plug, when the ground wire pin 41 is stored in the storage groove 14, only the two groups of second pin assemblies 2 of the plug can be plugged into the socket. At this time, it is only necessary to adjust the angles of the two rotating pins 21 through the driving member 22 so that the rotating pins 21 face the socket holes of the two-hole socket, and the plug-in connection with the two-hole socket can be realized; when the ground wire pin 41 is moved out of the storage groove 14, the ground wire pin 41 and the two rotating pins 21 of the plug can be plugged into the socket. Therefore, at this time, it is only necessary to adjust the angles of the two rotating pins 21 through the driving member 22 so that the rotating pin 21 faces the live wire socket and the neutral wire socket of the three-hole socket, and align the ground wire pin 41 with the ground wire socket, and the plug-in connection with the three-hole socket can be realized.

[0044] The plug can be switched between a two-hole socket and a three-hole socket, thereby improving the applicability of the electrical appliance and facilitating use by users.

[0045] Specifically, a stop structure is provided in the shell 1, and the second pin assembly 2 includes a driving structure. The stop structure can prevent the rotating pin 21 from rotating. The driving member 22 can abut against the rotating pin 21 to make the rotating pin 21 disengage from the stop structure, and drive the rotating pin 21 to rotate a preset angle through the driving structure.

[0046] The anti-rotation structure can make the rotating pin 21 stay in a stable position to ensure that the rotating pin 21 will not rotate during the use of the plug, so that the rotating pin 21 can be accurately inserted into the corresponding socket.

[0047] It is worth noting that the rotating pin 21 has a first plug-in portion 211, and the cross-section of the first plug-in portion 211 is non-circular, so as to avoid the problem that the first plug-in portion 211 can be inserted into the socket no matter how much the rotating pin 21 rotates. In this embodiment, the cross-sectional shape of the first plug-in portion 211 is rectangular. In other embodiments, the cross-sectional shape of the first plug-in portion 211 can also be other shapes, such as elliptical, oblong, diamond, etc. Similarly, the grounding pin 41 has a second plug-in portion 411, and the second plug-in portion 411 does not involve a change in angle, so the cross-sectional shape of the second plug-in portion 411 only needs to adapt to the shape of the grounding socket of the three-hole socket.

[0048] To facilitate assembly, the shell 1 includes a bottom shell 11 and an upper cover 12. The bottom shell 11 has an opening. The upper cover 12 can close the opening to form a cavity with the bottom shell 11. A cable 3 is arranged in the cavity. The cable 3 is electrically connected to the first pin assembly 4 and the second pin assembly 2. A storage groove 14 is opened on the top cover.

[0049] like Figure 8 As shown, the cable 3 includes a plurality of wires, each of which is provided with a conductive ring 31, the rotating pin 21 includes a first plug-in portion 211 and a first connecting rod 214, the first connecting rod 214 is partially located in the driving member 22, the cable 3 is passed through the driving member 22, and the conductive ring 31 is sleeved on a first connecting rod 214 and is electrically connected to the first connecting rod 214. When the rotating pin 21 rotates, the first connecting rod 214 rotates in the conductive sleeve, and the first connecting rod 214 is always in contact with the conductive sleeve, thereby ensuring the reliability of the electrical connection between the rotating pin 21 and the cable 3.

[0050] Similarly, the ground wire pin 41 includes a second plug-in portion 411 and a second connecting rod 412. The second plug-in portion 411 is rotatably disposed on the upper cover 12, and the second connecting rod 412 is passed through the upper cover 12. One end of the second connecting rod 412 is slidably abutted against the second plug-in portion 411, and the other end of the second connecting rod 412 is located in the conductive ring 31 of the cable 3 and is electrically connected to the conductive ring 31.

[0051] like Figure 5 to Figure 7 and Fig. 9As shown, a locking sleeve 13 is arranged in the housing 1, and a retaining rib 131 is convexly arranged on the inner wall of the locking sleeve 13, and the retaining rib 131 forms a rotation-stopping structure. The second pin assembly 2 is inserted into the locking sleeve 13, and the rotating pin 21 can move along the axial direction of the locking sleeve 13 and rotate relative to the locking sleeve 13. The driving structure includes a plurality of driven protrusions 212 arranged on the rotating pin 21 and a driving inclined surface 221 arranged on the driving member 22. The plurality of driven protrusions 212 are arranged along the circumference of the rotating pin 21. The two housings are connected end to end, the retaining rib 131 can abut against the driven protrusion 212 to prevent the rotating pin 21 from rotating, the driving member 22 can be movably arranged on the housing 1, and the driving inclined surface 221 extends along the circumference of the driving member 22 and is inclinedly arranged. When the driving member 22 moves toward the rotating pin 21, the driving inclined surface 221 abuts against the driven protrusion 212 and drives the rotating pin 21 to pass over the retaining rib 131, and the driven protrusion 212 can slide along the driving inclined surface 221 to change the angle of the rotating pin 21.

[0052] The retaining rib 131 can prevent the rotating pin 21 from rotating, which is equivalent to limiting the rotating pin 21 so that the rotating pin 21 can be kept at an angle. When the driving member 22 is pressed toward the rotating pin 21, the driving inclined surface 221 will generate a force on the driven protrusion 212 to rotate the rotating pin 21 relative to the driving member 22. When the rotating pin 21 moves along the axial direction of the locking sleeve 13 to be able to cross the retaining rib 131, the rotating pin 21 will rotate relative to the locking sleeve 13 under the driving force of the driving inclined surface 221, thereby changing the angle of the first plug-in portion 211, so that it can be respectively adapted to the two-hole socket and the three-hole socket at different angles.

[0053] The locking sleeve 13 is located in the cavity and fixedly connected to the bottom shell 11. The retaining rib 131 can be connected to the bottom plate of the bottom shell 11 or spaced from the bottom plate of the bottom shell 11. However, the top of the retaining rib 131 needs to be spaced from the upper cover 12, and the spacing allows the rotating pin 21 to pass over the retaining rib 131 when rotating. After one driven protrusion 212 passes over the retaining rib 131, the rotating pin 21 rotates until another driven protrusion 212 abuts against the retaining rib 131 and stops rotating. If the driving member 22 is continuously pressed, the rotating pin 21 can continue to rotate, so that the rotating pin 21 can be continuously rotated by continuously pressing the driving member 22, thereby adjusting the angle of the first plug-in portion 211.

[0054] In this embodiment, the retaining rib 131 prevents the rotation of the rotating pin 21 by abutting against the driven protrusion 212 in the circumferential direction. The driven protrusion 212 realizes the two functions of driving the rotating pin 21 to rotate and preventing the rotating pin 21 from rotating, which greatly simplifies the structure of the rotating pin 21 and saves space in the housing 1. It can be understood that in some embodiments, the rotating pin 21 can also be provided with a special protrusion structure to cooperate with the retaining rib 131 to prevent the rotating pin 21 from rotating.

[0055] like Figure 3 As shown, the retaining rib 131 corresponds to the driving inclined surface 221, the side wall of the driving member 22 is recessed with a guide groove 222, and one end of the guide groove 222 opens to the driving inclined surface 221, and the retaining rib 131 is partially located in the guide groove 222. The retaining rib 131 can limit the rotation of the driving member 22 through the guide groove 222, so that the driving member 22 can only move along the pressing direction, so the position of the driving inclined surface 221 of the driving member 22 in the circumferential direction will not change, and the rotation angle of the rotating pin 21 can be controlled. In addition, since the retaining rib 131 is located in the middle position of the driving inclined surface 221, when the rotating pin 21 abuts the retaining rib 131, in the moving direction of the driving member 22, the driving inclined surface 221 and the driven protrusion 212 partially overlap, thereby ensuring that the driving member 22 can drive the rotating pin 21 to rotate.

[0056] Furthermore, the slope of the end surface of the retaining rib 131 facing the rotating pin 21 is the same as the slope of the driving inclined surface 221. This arrangement allows the end surface of the retaining rib 131 to coincide with the driving inclined surface 221 when the driving member 22 is pressed, so that when the driven protrusion 212 passes over the retaining rib 131, the movement of the driven protrusion 212 is smoother.

[0057] like Figure 3 , Figure 5 to Figure 7 As shown, the driving structure also includes a plurality of driving protrusions 223 arranged on the driving member 22 along the circumferential direction, and each driving protrusion 223 forms a driving inclined surface 221 on a side facing the rotating pin 21. The plurality of driving protrusions 223 are connected end to end along the circumferential direction of the rotating pin 21 and correspond one to one with the plurality of driven protrusions 212. The plurality of driving inclined surfaces 221 can drive the rotating pin 21 to rotate through the plurality of driven protrusions 212, so that the driving force on the rotating pin 21 in the circumferential direction is evenly distributed, so as to avoid the deviation of the rotating pin 21 due to the biased force, thereby increasing the rotation resistance or getting stuck.

[0058] It is worth noting that the locking sleeve 13 is provided with a plurality of retaining ribs 131 at intervals along the circumferential direction.

[0059] It can be understood that, since the retaining rib 131 is located in the middle of the driving inclined surface 221, when the driving inclined surface 221 rotates the rotating pin 21 through the driven protrusion 212, the next driven protrusion 212 will abut the driving protrusion 223. When the driving member 22 moves in the direction away from the rotating pin 21, the rotating pin 21 and the driving member 22 have no relative movement in the circumferential direction. At this time, if the driving member 22 is pressed, the driving member 22 cannot continue to drive the rotating pin 21 to rotate. The operator needs to manually operate to rotate the rotating pin 21, which is inconvenient.

[0060] like Figures 4 to 7As shown, in order to solve the above problem, a driven inclined surface 213 is provided at one end of the driven protrusion 212 facing the driving member 22, and the inclination direction of the driven inclined surface 213 is the same as the inclination direction of the driving inclined surface 221. The end of the retaining rib 131 can abut against the driven inclined surface 213 and slide relative to the driven inclined surface 213.

[0061] When the driving member 22 moves to make the driven protrusion 212 pass over the retaining rib 131, the driven inclined surface 213 and the retaining rib 131 can be slidably matched by pressing the first plug-in portion 211, so that the rotating pin 21 continues to rotate until the driven protrusion 212 abuts against the retaining rib 131, completing the angle adjustment.

[0062] like Figure 5 to Figure 7 As shown, the pin assembly also includes a first elastic member 23, one end of the first elastic member 23 abuts against the shell 1, and the other end of the first elastic member 23 abuts against the rotating pin 21. The first elastic member 23 is configured to drive the rotating pin 21 to move so that the driven inclined surface 213 abuts against the retaining rib 131.

[0063] When the driving member 22 is pressed, the first elastic member 23 makes the rotating pin 21 always contact with the driving member 22, so that the driven protrusion 212 can move along the driving inclined surface 221. When the driven protrusion 212 slides to the bottom along the driving inclined surface 221 and contacts the next driving protrusion 223, as the driving member 22 moves away from the rotating pin 21, the first elastic member 23 drives the rotating pin 21 to move so that the rotating pin 21 contacts the retaining rib 131. At this time, the end of the retaining rib 131 slides relative to the driven inclined surface 213, thereby driving the driven protrusion 212 to rotate, so that the driven inclined surface 213 partially overlaps with the driving inclined surface 221 in the axial direction. At this time, the driving member 22 is continued to be pressed, and the rotating pin 21 can be driven to rotate through the driven inclined surface 213.

[0064] like Figure 5 to Figure 7 As shown, the pin assembly further includes a second elastic member 24, which is configured to drive the driving member 22 to move in a direction away from the rotating pin 21. The second elastic member 24 can reset the driving member 22 when it is not pressed. At this time, the driving member 22 is separated from the rotating pin 21, and the end of the retaining rib 131 slides relative to the driven inclined surface 213, thereby driving the driven protrusion 212 to rotate, so that the driven inclined surface 213 partially overlaps with the driving inclined surface 221 in the axial direction, so that each time the driving member 22 is pressed, the rotating pin 21 can be driven to rotate. In addition, the second elastic member 24 improves the relative stability between the driving member 22 and the housing 1, so that the driving member 22 will not shake relative to the housing 1, and it is also convenient for the operator to press the next time.

[0065] Specifically, the second elastic member 24 can be disposed between the driving member 22 and the rotating pin 21, or between the housing 1 and the driving member 22, as long as the driving member 22 can be moved away from the rotating pin 21. In this embodiment, the second elastic member 24 is located between the housing 1 and the driving member 22.

[0066] Since the live and neutral sockets of the two-hole socket are both arranged vertically, and the live and neutral sockets of the three-hole socket are at an angle of 30° to the vertical direction, in this embodiment, the driving member 22 has 12 driving protrusions 223, and the rotating pin 21 has 12 driven protrusions 212, so each time the driving member 22 is pressed, the rotating pin 21 will rotate 30°. It is worth noting that the driving protrusions 223 and the driven protrusions 212 can also be other numbers, such as 24, 36, etc., as long as the first plug-in portion 211 of the rotating pin 21 can be at an angle of 30 degrees to the vertical direction when the angle of the rotating pin 21 is adjusted.

[0067] In other embodiments, if the angles between the live wire socket and the neutral wire socket of the three-hole socket and the vertical direction are other angles, the number of the driving protrusions 223 and the driven protrusions 212 also need to be changed accordingly.

[0068] For the convenience of operation, the driving inclined surfaces 221 of the driving members 22 of the two second pin assemblies 2 are inclined in opposite directions, and accordingly, the driven inclined surfaces 213 of the rotating pins 21 are inclined in opposite directions. When the driving members 22 of the two second pin assemblies 2 are pressed respectively, the two rotating pins 21 rotate in opposite directions. When the two driving members 22 are pressed the same number of times, the first plug-in portions 211 of the two rotating pins 21 are always symmetrical, and can be adapted to a two-hole socket or a three-hole socket at the same time, which is convenient for adjustment.

[0069] like Figure 1 As shown, a clamping assembly 5 is provided in the receiving groove 14, and the clamping assembly 5 includes two clamping parts. When the ground wire pin 41 is received in the receiving groove 14, it is located between the two clamping parts and is clamped by the two clamping parts. The clamping assembly 5 can clamp and fix the ground wire pin 41, so that the ground wire pin 41 remains stable in the receiving groove 14, and prevents the ground wire pin 41 from rotating out of the receiving groove 14 and affecting the plug-in connection between the plug and the two-hole socket.

[0070] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
