[0002] The plug specifications used in the world vary, and can be initially divided into plugs comprising two pins or three pins, and then different types are configured according to the shape, size of each pin, and the position of each pin.

[0003] For example, a British specification plug comprises three long flat pins, two of which extend flat on a first plane, and the other pin extends flat on a second plane, which is perpendicular to the first plane. The aforementioned British specification plug comprising three pins often gives a person a heavy or stiff feeling, and if the plug is carried outside, it occupies a large space, which is inconvenient to carry. In order to reduce the space occupied by the plug when it is stored, the three pins can be designed to be foldable, and furthermore, due to the requirements of British safety specifications, the three pins must be able to be folded or unfolded simultaneously, so the three pins are designed to be connected to each other.

DETAILED DESCRIPTION

[0055] The technical means adopted by the utility model to achieve the predetermined utility model purposes are further described below in combination with the drawings and the preferred embodiments of the utility model.

[0056] Please refer to Figures 1 to 4 The utility model provides a plug structure, including a shell 10, a base 20, a connecting rod device 30, a grounding pin 40 and two firewire pins 50, and preferably, including a fixed cover 60 and two elastic sheets 70. In addition, the utility model includes an open state and a folding state. In this embodiment, the grounding pin 40 and the two firewire pins 50 are of British specifications, specifically, the grounding pin 40 and the two firewire pins 50 are square pins. In other embodiments, the utility model can also be a plug with three pins of other specifications.

[0057] The shell 10 is connected with the base 20, and the base 20 and the fixed cover 60 jointly form an internal space. Please refer to Figures 4 to 6 The connecting rod device 30 is arranged in the internal space and includes a first end 31, a second end 32, at least one grounding connecting rod 33, at least one firewire connecting rod 34, and at least one central connecting rod 35. In this embodiment, the connecting rod device 30 includes two grounding connecting rods 33, two firewire connecting rods 34, and two central connecting rods 35. The first end 31 and the second end 32 are opposite ends of the connecting rod device 30. The grounding connecting rod 33 is located at the first end 31 of the connecting rod device 30, and the firewire connecting rod 34 is located at the second end 32 of the connecting rod device 30. The central connecting rod 35 is pivotally arranged on the base 20, and the two ends of each central connecting rod 35 are respectively connected to one of the grounding connecting rods 33 and one of the firewire connecting rods 34, preferably, the two ends of each central connecting rod 35 are respectively pivotally arranged on one of the grounding connecting rods 33 and one of the firewire connecting rods 34, so that the grounding connecting rods 33, the firewire connecting rods 34 and the central connecting rods 35 can be connected with each other.

[0058] Please refer to Figure 5 and Figure 6The grounding pin 40 is pivotally mounted on the base 20 and connected to the first end 31 of the connecting rod device 30. When the plug structure is in the open state, the grounding pin 40 is perpendicular to the base 20. When the plug structure is in the closed state, the grounding pin 40 is retracted into the base 20 and parallel to the base 20. Please refer to [reference needed]. Figure 7 In this embodiment, the grounding pin 40 includes a grounding pin body 41 and a grounding pin shaft 42.

[0059] Please refer to Figures 7 to 9 The grounding plug body 41 includes at least one grounding plug connecting portion 411, which protrudes from the side edge of the grounding plug body 41 and connects to the connecting rod device 30. In this embodiment, the grounding plug body 41 has two grounding plug connecting portions 411, which protrude from opposite side edges of the grounding plug body 41 and are respectively rotatably mounted on two grounding connecting rods 33, thereby enabling the grounding connecting rods 33 to move. The grounding plug pivot 42 passes through the grounding plug body 41 and is mounted on the base 20, thereby allowing the grounding plug body 41 to rotate around the grounding plug pivot 42, and during rotation, it can drive the grounding connecting rods 33 to move. The grounding plug pivot 42 includes a grounding protrusion 421, which protrudes outward from the periphery of the grounding plug pivot 42.

[0060] Please refer to Figure 5 and Figure 6 Two live wire prongs 50 are pivotally mounted on the base 20 and respectively connected to two live wire connecting rods 34 of the connecting rod device 30. When the plug structure is in the open state, the two live wire prongs 50 are perpendicular to the base 20; when the plug structure is in the closed state, the two live wire prongs 50 are retracted into the base 20 and parallel to the base 20. Please refer to [reference needed]. Figure 7 Each live wire pin 50 includes a live wire pin body 51 and a live wire pin pivot 52.

[0061] Please refer to Figures 7 to 9 The live wire plug body 51 includes a live wire plug connecting portion 511 and a live wire stop portion 512. The live wire plug connecting portion 511 protrudes from the side edge of the live wire plug body 51 and connects to one of the live wire connecting rods 34. In this embodiment, the live wire plug connecting portion 511 is rotatably mounted on the live wire connecting rod 34. The live wire stop portion 512 is formed on the side edge of the live wire plug body 51, and when the live wire plug 50 rotates to be perpendicular to the base 20, the live wire stop portion 512 abuts against the base 20 and restricts the live wire plug body 51 from continuing to rotate. The live wire plug pivot 52 passes through the live wire plug body 51 and is disposed on the base 20, thereby driving the live wire plug connecting portion 511 when the live wire connecting rod 34 moves, so that the live wire plug body 51 can rotate about the live wire plug pivot 52. The live wire connector swivel 52 includes a live wire protrusion 521 that protrudes outward from the periphery of the live wire connector swivel 52.

[0062] Please refer to Figure 3 . The fixed cover 60 is located between the housing 10 and the base 20, and the link device 30 is disposed in the fixed cover 60. Please refer to Figures 10 to 13 . The fixed cover 60 includes at least one ground baffle 61 and two live baffle 62. The ground baffle 61 is attached to the ground protruding part 421, and when the ground pin 40 rotates, the ground baffle 61 needs to be pushed away from the ground pin shaft 42, so that the ground baffle 61 does not limit the rotation of the ground protruding part 421. In this embodiment, the fixed cover 60 includes two ground baffles 61, which are respectively located at both ends of the ground pin shaft 42, so that the ground pin shaft 42 can be stably arranged in a position perpendicular to the base 20 or parallel to the base 20, and will not rotate randomly. Each live baffle 62 is attached to one of the live pin shafts 52, and when the live pin 50 rotates, the live baffle 62 needs to be pushed away from the live pin shaft 52, so that the live baffle 62 does not limit the rotation of the live protruding part 521.

[0063] Please refer to Figures 4 to 6 . The elastic sheet 70 is fixedly arranged on the base 20, and each elastic sheet 70 includes a connecting hole 71. The connecting hole 71 is arranged at one end of the elastic sheet 70 and is used to connect an electric wire. When the plug structure is in the open state, the two live pins 50 are electrically connected to the electric wire through the two elastic sheets 70. Specifically, the electric wire can be fixed to the connecting hole 71 by soldering riveting, but the connection mode of the electric wire and the connecting hole 71 is not limited.

[0064] Please refer to Figures 7 to 9 . When the utility model is not used, the ground pin 40 and the two live pins 50 are parallel to the base 20 and are folded in the base 20. When the utility model is used, the ground pin 40 needs to be rotated to be perpendicular to the base 20, which will drive the ground link 33 to move towards the second end 32, and drive the two central links 35 to rotate, so that the two live links 34 are pulled by the two central links 35 to move towards the first end 31, and the two live pins 50 are rotated to be perpendicular to the base 20.

[0065] Therefore, the ground pin 40 and the two live pins 50 can be opened at the same time. At the same time, because the ground protruding part 421 abuts against the ground baffle 61, and the live protruding part 521 abuts against the live baffle 62, if the ground pin 40 and the two live pins 50 are rotated to be parallel to the base 20, a larger force needs to be applied to push the ground protruding part 421 to push the ground baffle 61 away from the ground pin shaft 42, and the live protruding part 521 to push the live baffle 62 away from the live pin shaft 52. Therefore, the opened ground pin 40 and the two live pins 50 are limited from rotating randomly.

[0066] When the user wants to retract the grounding prong 40 and the two live prongs 50 into the base 20, the grounding prong 40 is first rotated to be parallel to the base 20. The grounding prong 40 pulls the grounding link 33 to move toward the first end 31, and drives the two central links 35 to rotate. The two live links 34 are pushed by the two central links 35 to move toward the second end 32, and the two live prongs 50 are rotated to be parallel to the base 20. In this way, the grounding prong 40 and the two live prongs 50 can be retracted at the same time.

[0067] The grounding prong 40 and the two live prongs 50 are designed to be rotatable and can be retracted into the base 20, thereby reducing the space occupied by the utility model when stored. At the same time, a link device 30 is also designed, so that the grounding prong 40 and the two live prongs 50 can be rotated at the same time, which meets the electrical safety regulations and the external structure is relatively simple. In addition, in order to avoid the grounding prong 40 and the two live prongs 50 being tilted due to external force touch during use, the utility model also includes at least a grounding baffle 61, a live baffle 62, and a live stop portion 512, which are used to limit the position of the grounding prong 40 and the two live prongs 50.
