DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in combination with the drawings and specific embodiments.

[0026] In this embodiment, refer to Figures 1-10 The utility model discloses a universal power plug, which comprises a shell 1 and a pin 2, a push block 3 capable of reciprocating sliding is arranged in the shell 1, a rotating block 4 capable of rotating is symmetrically arranged on one side of the shell 1, the pin 2 is respectively arranged on the push block 3 and the rotating block 4, a reset assembly 5 connected with the rotating block 4 is arranged in the shell 1, and a support block 6 matched with the reset assembly 5 is arranged on one side of the push block 3. The reset assembly 5 comprises a connecting block 5A, a mounting block 5B and a swing rod 5C matched with the support block 6, the two ends of the connecting block 5A are connected with the rotating block 4, the rotating block 4 is provided with a connecting shaft matched with the connecting block 5A, the swing rod 5C is rotatably arranged on the mounting block 5B through a rotating shaft, one end of the swing rod 5C is connected with the connecting block 5A, and a reset spring 5D is arranged between the connecting block 5A and the shell 1. Through the cooperation of the support block 6 and the swing rod 5C, the conversion between a two-pin plug and a three-pin plug is realized.

[0027] When the pin 2 on the push block 3 is in the retracted state, the support block 6 on one side of the push block 3 is in contact with one end of the swing rod 5C, the connecting block 5A at the other end of the swing rod 5C is moved downward through the rotating cooperation of the mounting block 5B and the swing rod 5C, the reset spring 5D is compressed, and the two rotating blocks 4 are rotated, so that the pin 2 on the rotating block 4 is rotated, and the two-pin plug state is maintained. When the pin 2 on the push block 3 is extended out of the shell 1, the swing rod 5C loses the limitation of the support block 6, so that the connecting block 5A at the other end of the swing rod 5C is moved upward under the action of the reset spring 5D, the pin 2 on the rotating block 4 is rotated, and the pin 2 is converted from the two-pin state to the three-pin state.

[0028] The design of the convertible plug makes the power plug applicable to various electrical equipment such as power strips, branch plugs, etc., improving the flexibility and convenience of use. Users can easily switch between two-pin and three-pin plugs according to actual needs. Moreover, the inner wall of the shell 1 is coated with a lubricant that cooperates with the push block 3 and the support block 6. The lubricant reduces the friction between the push block 3 and the support block 6 during reciprocating motion, making the sliding process smoother, thereby avoiding situations such as jamming.

[0029] The pins 2 are respectively mounted on the push block 3 and the rotating block 4 by adhesive, which ensures that the pins 2 are firmly fixed while also providing a sealing effect. The pins 2 on the push block 3 serve as ground terminals, while the pins 2 on the rotating block 4 are respectively neutral and live terminals. The shell 1 has conductive blocks inside that connect with the ground, neutral, and live terminals. The conductive blocks have conductive pieces on one side that cooperate with the pins 2, and several threaded holes are provided on the conductive blocks. The conductive pieces allow the pins 2 to maintain good electrical connection during movement. Moreover, the threaded holes enable the conductive blocks to be quickly connected with the live, neutral, and ground lines, thereby achieving stable connection between the pins 2 and the power cord.

[0030] The shell 1 has a sliding groove 1A that cooperates with the connecting block 5A. One side of the connecting block 5A has a sliding block 51A that cooperates with the sliding groove 1A. Through the cooperation of the sliding groove 1A and the sliding block 51A, the connecting block 5A smoothly slides within the shell 1, avoiding tilting during sliding and causing the rotating blocks 4 on both sides to rotate inconsistently, thereby affecting the normal conversion of the pins 2.

[0031] Meanwhile, one side of the shell 1 is provided with a limiting groove 1B, and the push block 3 is provided with a limiting block 3A that cooperates with the limiting groove 1B. The limiting groove 1B and the limiting block 3A are respectively provided with a clamping block 1C and a clamping groove 3B that cooperate with each other. Through the cooperation of the limiting groove 1B and the limiting block 3A, the sliding distance of the push block 3 is controlled, thereby ensuring that the pins 2 do not exceed the predetermined travel range during conversion. Through the cooperation of the clamping block 1C and the clamping groove 3B, the limiting block 3A can be fixed when it slides to both ends of the limiting groove 1B, preventing the pins 2 on the push block 3 from accidentally extending or retracting into the shell 1 during use, which affects the normal use of the power plug.

[0032] The outer side of the limiting groove 1B is also provided with a flexible sealing gasket, and the shell 1 fixes the flexible sealing gasket around with a cover plate. The flexible sealing gasket is provided with a groove that cooperates with the push block 3. Since the sealing gasket is made of flexible material, the groove can be deformed by being squeezed. This not only does not affect the sliding of the push block 3, but also effectively prevents dust and moisture from entering the interior of the shell, ensuring that the power plug can maintain good working condition in various environments.

[0033] Furthermore, the push block 3 is connected and matched with the supporting block 6 through the connecting plate 7, both ends of the connecting plate 7 are provided with fixing blocks 7A, and the push block 3 and the supporting block 6 are provided with fixing grooves 8 matched with the fixing blocks 7A. The fixing blocks 7A at both ends of the connecting plate 7 are matched with the fixing grooves 8 on the push block 3 and the supporting block 6 respectively, so that the part manufacturing is convenient, and meanwhile, it is ensured that the supporting block 6 can slide along with the push block 3 when the push block 3 slides, so as to be matched with the swing rod 5C, and the rotating angle of the rotating block 4 is controlled. The interference fit is adopted between the fixing block 7A and the fixing groove 8, so that the stability of the connection is ensured, and the connecting plate 7 is prevented from falling off in the use process, so as to avoid affecting the conversion of the plug.

[0034] In the embodiment, the mounting block 5B is provided with a through groove matched with the supporting block 6, and both sides of the through groove are provided with waist-shaped grooves matched with the fixing blocks 7A. The through groove is in width abutment with the supporting block 6, and the waist-shaped grooves at both sides of the through groove are matched with the fixing blocks 7A, so that the sliding of the supporting block 6 is more stable, and it is ensured that the supporting block 6 will not shake unnecessarily in the sliding process, so as to improve the stability and reliability of the entire power plug.

[0035] Furthermore, one side of the supporting block 6 is provided with a guide structure 6A. The guide structure 6A is used for being matched with the swing rod 5C, and through the matching of the guide structure 6A and the swing rod 5C, the supporting block 6 can keep a certain directionality when being in contact with the swing rod 5C, so as to ensure the stable movement of the swing rod 5C in the plug conversion process. The friction and wear of the swing rod 5C in the movement are reduced, so as to prolong the service life.

[0036] The utility model discloses the beneficial effects: through the cooperation of supporting block 6 and reset component 5, make rotating block 4 with the sliding of push block 3 synchronous rotation. When the plug 2 on the push block 3 slides with the push block 3, the plug 2 on the rotating block 4 will also rotate accordingly. So as to realize the conversion of two-foot plug and three-foot plug. Make the user in the use process, can according to different power interface flexible switching, thereby improve the applicability and convenience of power plug.
