[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] This embodiment relates to a multi-functional adapter socket, such as... Figure 1-9 As shown, it includes a housing assembly 100, a socket hardware assembly 200, a PCB board 300, a cover assembly 400, several sets of plug assemblies 500, and a push button assembly 600.

[0034] The housing assembly 100 has a mounting cavity with an opening at the top. Several pin extension holes 101 communicating with the mounting cavity are passed through the bottom of the housing assembly 100. A cover assembly 400 covers the opening of the mounting cavity and has a socket hole 401 for external plug insertion. The socket hardware assembly 200, PCB board 300, and pin assembly 500 are all housed within the mounting cavity, with the socket hardware assembly 200 electrically connected to the PCB board 300. A push button assembly 600 passes through the housing assembly 100 to push the pin assembly 500 out or retract from the housing assembly 100. Several push slots 102 are arranged side-by-side on the side wall of the housing assembly 100. The push button assembly 600 passes through the push slots 102 and connects to the pin assembly 500. When the user pushes the pin assembly 500 out of the housing assembly 100 by pushing the component, the pushing component moves downward along the push groove 102, causing the pin assembly 500 to extend out of the housing assembly 100 through the pin telescopic hole 101, making contact and conducting electricity with the socket hardware component 200, thus enabling the pin assembly 500 to supply power to the PCB board 300 through the socket hardware component 200. When the user pushes the pin assembly 500 back into the mounting cavity by pushing the component, the pushing component moves upward along the push groove 102, causing the pin assembly 500 to retract into the mounting cavity, at which point the pin assembly 500 separates from the housing assembly 100 and is de-energized.

[0035] The adapter also includes a sliding baffle assembly 700, which is slidably disposed within the mounting cavity and located behind the push groove 102. The sliding baffle assembly 700, under its own restoring force, blocks the push groove 102 and restricts the push button assembly 600 to extend only one prong assembly 500 out of the housing assembly 100 at a time. This invention includes several retractable prong assemblies 500. Users can select the appropriate prong assembly 500 according to their electrical specifications. Under the action of the sliding baffle assembly 700, only one of the prong assemblies 500 located in the housing assembly 100 can extend to meet the plugging requirements, thereby avoiding the risks that may arise from multiple prongs extending simultaneously and ensuring the reliability of the electrical plug conversion.

[0036] Optionally, the plurality of pin assemblies 500 include: a British pin assembly 510, an American pin assembly 520, an Australian pin assembly 530, and a European pin assembly 540. Four push-button assemblies 600 are provided, each connected to one of the four pin assemblies 500. These four push-button assemblies 600 are designated as a first push-button assembly 610, a second push-button assembly 620, a third push-button assembly 630, and a fourth push-button assembly 640. In this embodiment, the first push-button assembly 610 is fixedly connected to the British pin assembly 510 by screws, the second push-button assembly 620 is fixedly connected to the American pin assembly 520, the third push-button assembly 630 is fixedly connected to the Australian pin assembly 530, and the fourth push-button assembly 640 is fixedly connected to the European pin assembly 540. The pin extension holes 101 on the bottom surface of the housing assembly 100 are arranged opposite to each of the pin assemblies 500.

[0037] In this embodiment, several positioning posts 110 are erected inside the mounting cavity, and each pin assembly 500 can move up and down along different positioning posts 110. The European-style pin assembly 540 includes a pin sleeve 541, an insulating connecting bridge 542, and a European-style pin 543. One end of the European-style pin 543 is disposed on the lower surface of the insulating connecting bridge 542. The fourth push button assembly 640 is fixed to the upper surface of the insulating connecting bridge 542. The insulating connecting bridge 542 and the European-style pin 543 are inserted together into the pin sleeve 541. The pin sleeve 541 is fitted onto the positioning posts 110 and can move up and down relative to the positioning posts 110. The upper part of the side wall of the pin sleeve 541 is provided with a vertically oriented strip guide groove, and the side wall of the insulating connecting plate protrudes with a slider portion that can slide along the strip guide groove. When the European-style plug assembly 540 is launched, the fourth push button assembly 640 pushes the insulating connecting plate downward, causing the European-style plug 543 to extend out of the plug sleeve 541 until the sliding block slides to the lower end of the strip guide groove. The fourth push button assembly 640 continues to push downward, causing the plug sleeve 541 and the European-style plug 543 to move downward together and extend out of the housing assembly 100.

[0038] Furthermore, to ensure that the sliding baffle assembly 700 can block the push groove 102 under its own restoring force while limiting the ejection of only one pin assembly 500 at a time, a sliding groove 103 is provided at the bottom of the mounting cavity and behind the push groove 102. A limiting rod 120 is provided on the inner side wall of the mounting cavity and at one end of the sliding groove 103. The sliding baffle assembly 700 includes a first baffle 710, a second baffle 720, a third baffle 730, a fourth baffle 740, and an elastic element 750 arranged sequentially from left to right. The lower ends of the first baffle 710, the second baffle 720, the third baffle 730, and the fourth baffle 740 are all slidably assembled in the sliding groove 103. The first push button assembly 610 is limited between the limiting rod 120 and the first baffle 710. The second push button assembly 620 is limited between the first baffle 710 and the second baffle 720. The third push button assembly 630 is limited between the second baffle 720 and the third baffle 730. The fourth push button assembly 640 is positioned between the third baffle 730 and the fourth baffle 740. An elastic member 750 is disposed within the mounting cavity, with both ends abutting against the fourth push button assembly 640 and the inner sidewall of the housing assembly 100, respectively. In this embodiment, the upper parts of the first baffle 710 and the second baffle 720 are provided with notches to accommodate the second push button assembly 620; the upper parts of the second baffle 720 and the third baffle 730 are provided with notches to accommodate the third push button assembly 630; and the upper parts of the third baffle 730 and the fourth baffle 740 are provided with notches to accommodate the fourth push button assembly 640.

[0039] When all the pin assemblies 500 are retracted into the mounting cavity, under the action of the elastic member 750, the two sides of the first baffle 710 abut against the limiting rod 120 and one side of the second baffle 720 respectively, the third baffle 730 abuts against the other side of the second baffle 720 and one side of the fourth baffle 740 respectively, and the other side of the fourth baffle 740 abuts against the elastic member 750. When the fourth push button assembly 640 is pushed down, the fourth baffle 740 moves towards the elastic member 750 to open the push groove 102 where the fourth push button assembly 640 is located, thereby realizing the ejection of the European-style pin assembly 540. At this time, if other push button assemblies 600 are pushed down, the other baffles will not open the blocked push groove 102. When the fourth push button assembly 640 is pushed to reset, the fourth baffle 740 moves towards the limiting rod 120 under the restoring force of the elastic member 750, so that the fourth baffle 740 blocks the slide groove, preventing foreign objects from entering the housing when the adapter is not in use.

[0040] When the third push button assembly 630 is pushed downwards, the third baffle 730 and the fourth baffle 740 move simultaneously toward the elastic member 750 to open the push groove 102 where the third push button assembly 630 is located. When the third push button assembly 630 is reset, the third baffle 730 and the fourth baffle 740 move simultaneously toward the limiting rod 120 under the action of the elastic member 750, so that the third baffle 730 and the fourth baffle 740 block the two push grooves 102 respectively, and so on.

[0041] Optionally, the first baffle 710 and the second baffle 720 are at the same height, and the third baffle 730 and the fourth baffle 740 are at the same height, with the first baffle 710 being less than the third baffle 730. Three strip-shaped inserts 410 protrude downwards from the lower end of the cover assembly 400. These strip-shaped inserts 410 are inserted into the upper part of the push groove 102 where the first push button assembly 610, the second push button assembly 620, and the third push button assembly 630 are located, and are positioned above the push button assembly 600.

[0042] Optionally, to facilitate the installation of the elastic element 750, a limiting part 130 is provided on the inner side wall of the mounting cavity at the other end of the sliding groove 103. A limiting groove 104 is formed on the side of the limiting part 130 facing the sliding groove 103, and the elastic element 750 is located within the limiting groove 104. Optionally, the width of the limiting groove 104 is less than or equal to the sum of the widths of the two push grooves 102.

In this design, the guide post 811 of the first protective door 810 passes through the second protective door 820 and through the through hole 422 of the limiting frame 421, so that the two protective doors can slide along the same track, reducing the risk of misalignment during the sliding process of the protective door, which would make it difficult for the plug to be inserted into the adapter socket of this application, effectively ensuring the safety of use.

[0050] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
