[0044] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] In the prior art, there is a method of using an external power supply to supply power to the socket. In this method, a plug of the external power supply is plugged into the socket to supply power to the socket.

[0049] In this mode, for safe use of electricity, the plug cannot be unplugged when the socket is powered on. The plug can only be unplugged when the socket is powered off. However, in practice, when the socket is powered on, there are cases where the user accidentally unplugs the plug, or the plug becomes loose.

[0050] In order to solve the above problems, this patent provides a safety socket, which aims to meet the requirement that the plug cannot be pulled out when the socket is powered on and must be firmly plugged into the socket.

[0051] For ease of understanding, the specific implementation of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0052] See also Figure 1-6, a safety socket, comprising a shell 100, a holder 200 and an on-off switch 300; a groove 110 is provided on the shell 100, and a first through hole 111 is provided at the bottom of the groove 110, and the first through hole 111 is used for inserting the pin of the plug; a second through hole 112 is provided on the side wall of the groove 110; the holder 200 is movably arranged inside the socket and is located at the second through hole 112, the holder 200 has a first holding portion 210, and the first holding portion 210 can extend from the second through hole 112; the on-off switch 300 is used to control the external power supply of the socket, and the on-off switch 300 is linked to the holder 200; the plug is used to supply power to the socket, and the plug is provided with a second holding portion 400; when the on-off switch 300 is pressed to connect the circuit in the socket, the first holding portion 210 extends from the second through hole 112 under the action of the on-off switch 300 and is clamped on the second holding portion 400 to lock the plug and the socket.

[0053] The first holding portion 210 can be a convex portion, a convex column, a bump, a hook, etc., and the second holding portion 400 can be a groove, a blind hole, a through hole, etc. The linkage between the on-off switch 300 and the holding member 200 can be direct linkage, for example, after pressing the on-off switch 300, the holding member 200 is pushed by the on-off switch 300 and moves toward the second through hole 112, or it can be indirect linkage, for example, the holding member 200 is set on a component for movement, and after pressing the on-off switch 300, the moving component is pushed by the on-off switch 300 and moves toward the second through hole 112. When the on-off switch 300 is not pressed, the first holding portion 210 can be located outside the second through hole 112, or it can be partially or completely located inside the second through hole 112. In this embodiment, the first holding portion 210 is locked to the second holding portion 400 to lock the plug and the socket. In this way, the plug cannot be pulled out when the socket is powered on and is firmly plugged into the socket.

[0054] Based on the above implementation, there are many implementations for the first holding portion 210 to extend from the second through hole 112 and be held in the second holding portion 400 under the action of the on-off switch 300. This embodiment provides the following implementations. Figure 5-7The safety socket further includes a first displacement member 500, on which the retaining member 200 is disposed. A first inclined surface 510 is formed on the first displacement member 500, and a second inclined surface 310 is formed on the on-off switch 300. When the on-off switch 300 is pressed, the second inclined surface 310 pushes the first inclined surface 510, causing the first displacement member 500 to move toward the second through-hole 112. With the help of the first displacement member 500, the retaining member 200 also moves toward the second through-hole 112 when the on-off switch 300 is pressed. Consequently, the first retaining portion 210 extends from the second through-hole 112 and retains the second retaining portion 400 of the plug. The use of the clamping member 200 and the displacement member allows the manufacturer to separately design and produce the displacement member according to the different internal structures of the socket to adapt to different sockets. The manufacturer can also separately design and produce the clamping member 200 according to the different second clamping parts 400 of the plug to adapt to different plugs. Finally, the required displacement member and clamping member 200 can be combined and used according to actual conditions.

[0055] Furthermore, there is a problem of how to set the clamping member 200 on the first displacement member 500. In order to solve the above problem, this embodiment provides the following implementation method. Figure 7-11 A spring 600 is disposed between the sidewall of the first displacement member 500 and the clamping member 200. The clamping member 200 is provided with a first protrusion 220, and the first displacement member 500 is provided with a third clamping member 520. The first protrusion 220 is embedded in the third clamping member 520. This implementation allows the clamping member 200 to be disposed on the first displacement member 500 and to move with the first displacement member 500.

[0056] Furthermore, there is a problem of how to separate the first holding portion 210 from the second holding portion 400 after the on-off switch 300 is turned off. In order to solve the above problem, this embodiment provides the following implementation method. Figure 11 The safety socket also includes a first return spring 700, which is used to return the first displacement member 500 to its initial position when the on-off switch 300 is turned off. The retaining member 200 moves with the first displacement member 500. During the process of the first return spring 700 returning the first displacement member 500, the first retaining portion 210 disengages from the second retaining portion 400.

[0057] It should be noted that there are other implementations for the first holding portion 210 to extend from the second through hole 112 and be held in the second holding portion 400 under the action of the on-off switch 300. This embodiment provides the following implementations. Figure 6 、 Figure 12 、 Figure 13 and Figure 15The safety socket also includes a linkage member 800 and a second displacement member 900. The retaining member 200 is disposed on the second displacement member 900. A third inclined surface 810 is formed on the linkage member 800, and a fourth inclined surface 320 is formed on the on-off switch 300. When the on-off switch 300 is pressed, the fourth inclined surface 320 pushes the third inclined surface 810, causing the linkage member 800 to move, thereby coordinating the movement of the second displacement member 900 toward the second through-hole 112. The linkage member 800 coordinating the movement of the second displacement member 900 toward the second through-hole 112 allows the second displacement member 900 to be positioned near the second through-hole 112. With the linkage member 800, the first retaining portion 210 is quickly secured to the second retaining portion 400. The linkage member 800 also ensures that the second displacement member 900 can move toward the second through-hole 112 even in sockets with a large distance between the on-off switch 300 and the second through-hole 112 when the on-off switch 300 is pressed. In addition, the shape of the linkage member 800 can be set to avoid the shape of internal socket components such as conductors, screw posts or socket units 1000, so that when the linkage member 800 is pushed by the on-off switch 300, it will not affect the internal socket components.

[0058] Based on the above implementation, there is a problem of how to set the clamping member 200 on the second displacement member 900. In order to solve the above problem, this embodiment provides the following implementation. Figure 16 A spring 600 is disposed between the sidewall of the second displacement member 900 and the retaining member 200. The retaining member 200 is provided with a second protrusion 230, and the second displacement member 900 is provided with a fourth retaining member 910. The second protrusion 230 engages with the fourth retaining member 910. This implementation allows the retaining member 200 to be disposed on the second displacement member 900 and to move with the second displacement member 900.

[0059] Based on the above implementation, there is a problem of how to realize the linkage member 800 to link the second displacement member 900 to move toward the second through hole 112. In order to solve the above problem, this embodiment provides the following implementation. Figure 16 and Figure 17The linkage member 800 includes a linkage arm 820. The second displacement member 900 is formed with a fifth inclined surface 920 and a sixth inclined surface 821. When the on-off switch 300 is pressed, the sixth inclined surface 821 pushes the fifth inclined surface 920, causing the second displacement member 900 to move toward the second through-hole 112. This implementation allows the linkage member 800 to move when the on-off switch 300 is pressed. Simultaneously, the linkage member 800 pushes the fifth inclined surface 920 via the sixth inclined surface 821, causing the second displacement member 900 to move toward the second through-hole 112. In the implementation in which the linkage member 800 includes the linkage arm 820, the linkage arm 820 can be extended toward the second through-hole 112, thereby adapting to a socket whose second through-hole 112 is relatively far from the on-off switch 300.

[0060] Furthermore, the fifth inclined surface 920 has multiple implementations, see Figure 14 and Figure 15 The socket unit 1000 is disposed below the groove 110, and the linkage arm 820 is located near the socket unit 1000. The second displacement member 900 is formed with a third protrusion 930, which is located at the bottom of the second displacement member 900. The fifth inclined surface 920 is disposed on the third protrusion 930. Because the third protrusion 930 is located at the bottom of the second displacement member 900, when the fifth inclined surface 920 is pushed by the sixth inclined surface 821, it does not affect the movement of the retaining member 200 along with the second displacement member 900.

[0061] Furthermore, there is a problem of how to make the connection between the plug and the socket more secure. To solve the above problem, this embodiment provides the following implementation method. Figure 15-17 Each linkage arm 820, retaining member 200, second displacement member 900, and second through-hole 112 is provided in pairs; the two retaining members 200 are provided on the two second displacement members 900, respectively; the two second through-holes 112 are provided on two opposing side walls of the recess 110, respectively. When the on-off switch 300 is pressed, the sixth inclined surfaces 821 on the two linkage arms 820 push the fifth inclined surfaces 920 on the two second displacement members 900, respectively, causing the two second displacement members 900 to move toward the two second through-holes 112. This implementation allows the plug to be clamped and secured by the retaining members 200 from both sides, further strengthening the connection between the plug and the socket.

[0062] Based on the above implementation, there is a problem of how to separate the first holding portion 210 from the second holding portion 400 after the on-off switch 300 is turned off. In order to solve the above problem, this embodiment provides the following implementation. Figure 17The safety socket also includes a second return spring 1100, which is used to return the second displacement member 900 to its initial position when the on-off switch 300 is turned off. The retaining member 200 moves with the second displacement member 900. During the process of the second return spring 1100 returning the second displacement member 900, the first retaining portion 210 disengages from the second retaining portion 400.

[0063] It should be noted that the first holding portion 210 has multiple implementations, and this embodiment provides the following implementations. Figure 5 The upper end surface of the first retaining portion 210 is an inclined surface or an arc-shaped convex surface. This implementation allows the retaining member 200 to be reset effectively when the first retaining portion 210 still extends out of the second through hole 112 by abutting the end surface of the plug against the upper end surface of the first retaining portion 210. Similarly, this implementation allows the retaining member 200 to be reset by abutting the end surface of the plug against the upper end surface of the first retaining portion 210 without providing a reset member such as a reset spring.

[0064] It should be noted that the on-off switch 300 in this embodiment includes a button 330 and a trigger unit 340. The trigger unit 340 includes a component (such as an elastic component) that can reset the button 330. When the button 330 is pressed again, the button 330 can be reset. The button 330 is linked to the clamping member 200. In order to ensure that after the first clamping portion 210 is clamped on the second clamping portion 400, the button 330 will not reset or deflect without pressing the button 330 again, thereby ensuring the clamping effect, this embodiment provides the following implementation method. Please refer to Figure 18 A locking structure 1200 is provided within the housing 100 to prevent the button from resetting after the on-off switch 300 is pressed to connect the circuit in the socket. The locking structure 1200 includes a first locking member 1210 fixed to the inside of the button 330 and a second locking member 1220 located below the button 330. The second locking member 1220 is fixed to the trigger unit 340. The lower end of the first locking member 1210 is provided with a clamping head 1211, and the upper end of the second locking member 1220 is provided with a clamping claw 1221. When the switch is pressed, the clamping claw 1221 clamps the clamping head 1211, so that the button 330 and the trigger unit 340 move synchronously. In this implementation, the second locking member 1220 is fixed to the trigger unit 340, which can be a component fixed to the trigger unit 340 for resetting the button 330. When the button 330 is pressed, the clamping jaw 1221 moves downward and is clamped by the clamping jaw 1221, thereby achieving relative fixation of the button 330 relative to the trigger unit 340; when the second locking member 1220 is fixed to the component of the trigger unit 340 for resetting the button 330, the clamped button 330 will move synchronously with the component, thereby achieving synchronous movement of the button 330 and the trigger unit 340.

[0065] Based on the above implementation, there is a problem of how to realize the clamping jaws 1221 clamping the chuck 1211. In order to solve the above problem, this embodiment provides the following implementation. Figure 18 and 19 The trigger unit includes a trigger housing 341, with the second locking member 1220 at least partially housed within the trigger housing 341. When the clamping jaws 1221 are housed within the trigger housing 341, the trigger housing 341 drives the clamping jaws 1221 to clamp the chuck 1211. In this implementation, the clamping jaws 1211 are in an open state when not housed within the trigger housing 341. As the clamping jaws 1221 are gradually housed within the trigger housing 341, the clamping jaws 1221 gradually move toward the center. The housing of the clamping jaws 1221 within the trigger housing 341 can be achieved by the clamping jaws 1221 being pushed by the chuck 1211 into the trigger housing 341.

[0066] It should be noted that when the first holding portion 210 is held by the second holding portion 400, if an external force acts on the plug (for example, if the plug is pulled hard by an operator), the plug may tilt up. To avoid the above situation, this embodiment provides the following implementation method. Figure 20 A limit member 1300 is disposed within the housing 100 and has a limit protrusion 1310 formed thereon. When the plug pin 01 is inserted into the first through-hole 111, the limit protrusion 1310 abuts against the plug pin 01 from the side, securing it. The limit protrusion 1310 prevents the plug pin 01 from moving or swinging, thereby preventing the plug from tilting.

[0067] In summary, the safety socket provided in the embodiment of the present application includes a housing 100, a holder 200 and an on-off switch 300; the housing 100 is provided with a groove 110, the bottom of the groove 110 is provided with a first through hole 111, and the first through hole 111 is used for inserting the pin of the plug; the side wall of the groove 110 is provided with a second through hole 112; the holder 200 is movably provided inside the socket and is located at the second through hole 112, and the holder 200 has a first holding portion 2 10. The first retaining portion 210 can extend from the second through-hole 112. The on-off switch 300 is used to control the power supply of the socket, and the on-off switch 300 is linked to the retaining member 200. The plug is used to supply power to the socket and is provided with a second retaining portion 400. When the on-off switch 300 is pressed to connect the circuit in the socket, the first retaining portion 210, under the action of the on-off switch 300, extends from the second through-hole 112 and retains on the second retaining portion 400, locking the plug in place. This ensures that the plug cannot be removed when the socket is powered, ensuring a secure connection.

Any equivalent structural transformation made by using the contents of the present description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
