However, since existing power strips or sockets are all two-prong or three-prong, in practical use, especially when using three-prong plugs, some power strips have two prongs. One prong needs to be bent and discarded, and the other two angled prongs need to be straightened for use, which is inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an interchangeable multi-functional power plug, including a mounting base, a top cover that is fastened to the mounting base, and a first plug, a second plug, and a third plug located on the mounting base and extending out of the top cover, characterized in that: the second plug and the third plug are rotatably mounted on the mounting base, the mounting base is provided with a first plug for driving the second plug and the third plug to rotate, and the first plug is connected to the second plug and the third plug through a drive assembly.

[0015] according to Figure 1-6 This embodiment discloses an interchangeable multi-functional power plug, including a mounting base 1, a top cover 2 that is fastened to the mounting base 1, and a first plug 3 (connected to the ground wire), a second plug 4, and a third plug 5 located on the mounting base 1 and extending out of the top cover 2. The second plug 4 and the third plug 5 are rotatably mounted on the mounting base 1. The mounting base 1 is provided with a first plug 3 for driving the second plug 4 and the third plug 5 to rotate. The first plug 3 is connected to the second plug 4 and the third plug 5 through a drive assembly. By movably mounting the first plug on the mounting base, it is convenient for the first plug to move up and down, thereby driving the second plug and the third plug to rotate through the drive assembly, changing the original three-prong plug into a two-prong plug, which is convenient to use.

[0016] The present invention is further configured such that: the driving assembly includes a guide seat 6 located between the second insert 4 and the third insert 5 and fixedly mounted on the mounting base 1, and a guide strip 7 slidably mounted on the guide seat 6; a push rod 8 fixedly connected to the guide strip 7 at one end near the first insert 3; a push block 9 fixedly connected below the first insert 3; the push block 9 abutting against the push rod 8; half gears 10 fixedly mounted on the second insert 4 and the third insert 5 respectively; a toothed groove 11 adapted to the half gear 10 opened on the guide strip 7; a guide rod 12 fixedly connected to the guide strip 7 at one end away from the first insert 3; a spring 13 sleeved on the guide rod 12; and a sleeve 14 fixedly mounted on the upper cover 2; the guide rod 12 and the spring 13 are located on the sleeve. Inside 14, the other end of the spring 13 abuts against the upper cover 2. A reset spring 15 is provided below the push block 9. A placement groove 16 is provided on the mounting base 1. The spring 15 is located in the placement groove 16. The upper end of the spring 13 abuts against the push block 9. When it is necessary to convert the three-prong plug to a two-prong plug, the first plug rod will contact the housing of the plug bar, pushing the first plug rod to move in the direction of the reset spring. The first plug rod drives the push block to move, the push block drives the push rod to move, the push rod pushes the guide bar to move on the guide seat, the guide bar drives the half gear to move, and the half gear drives the second and third plug rods to rotate into a straight bar. At this time, the spring in the sleeve is in a compressed state, and the upper end of the first plug rod is flush with the upper cover, which facilitates the conversion of the three-prong plug to a two-prong plug and makes it convenient to use.

[0017] The present invention is further configured such that: the second insertion rod 4 and the third insertion rod 5 are respectively provided with rotating components, the rotating components including a rotating sleeve 17 fixedly disposed on the second insertion rod 4 and a mounting sleeve 18 fixedly disposed on the mounting base 1, the rotating sleeve 17 being rotatably disposed on the mounting sleeve 18, the upper end of the rotating sleeve 17 being stepped, the step of the rotating sleeve 17 abutting against the upper cover 2, and the lower end of the rotating sleeve abutting against the lower end of the mounting sleeve. By setting the rotating sleeve and the mounting sleeve to cooperate, the rotation of the second insertion rod and the third insertion rod is facilitated. The step of the rotating sleeve abutting against the upper cover plays a limiting role, preventing the second insertion rod and the third insertion rod from running out of the round hole of the upper cover.

[0018] The present invention is further configured such that: the push rod 8 is inclined toward the push block 9, and the push block 9 is provided with an inclined groove that matches the push rod, so as to facilitate pushing the push rod to move.

[0019] The present invention is further configured such that: a conductive sheet 20 is provided on the mounting base 1, the conductive sheet 20 is connected to the push block 9, the push block slides inside the conductive sheet, and the lower ends of the second insertion rod 4 and the third insertion rod 5 pass through the rotating sleeve and are connected to a terminal 21. The terminal is located below the mounting sleeve and is connected to a wire to facilitate the supply of power.

[0020] The working principle of this utility model is as follows: When converting a three-prong plug to a two-prong plug, the first plug rod contacts the socket housing, pushing it towards the return spring. The first plug rod drives the push block, which in turn drives the push rod. The push rod pushes the guide bar onto the guide seat, which in turn drives the half gear. The half gear drives the second and third plug rods to rotate into a straight line (after the first plug rod moves down one-tenth of its length, the second and third plug rods are in a straight line configuration, the push rod disengages from the inclined groove, and the first plug rod continues to move downward, contacting the push rod again). The first plug continues to move downwards without causing the second and third plugs to rotate, remaining in a straight position (allowing the second and third plugs to be inserted into the socket). At this time, the spring inside the sleeve is compressed, the upper surface of the first plug is flush with the top cover, and the second and third plugs are also fully inserted into the socket, facilitating the conversion from a three-prong to a two-prong plug. When the entire plug is pulled out, the return spring causes the first plug to move upwards. The return spring's elasticity is greater than the spring's elasticity, and the spring pushes the guide bar to move, thereby causing the second and third plugs to rotate, resetting them for three-prong use.

[0021] The above description is only a preferred embodiment of the present utility model. The present utility model is not limited to the above-described embodiments. Any modifications, alterations or equivalent substitutions made by those skilled in the art based on the above description shall fall within the scope of protection of the present utility model.
