Description

Technical Field

[0001] This utility model relates to the field of converter technology, and in particular to a multifunctional combination plug. Background Technology

[0002] With increasingly close international exchanges, the interoperability of electronic products from different countries is becoming more and more widespread. However, because plug standards are not completely unified from country to country, a single plug cannot be used worldwide. Travelers need to bring plugs compatible with those countries to power their electronic devices, causing considerable inconvenience for those traveling internationally or on business trips. To avoid affecting the use of these electronic products in different countries, people often use adapter plugs to solve this problem.

[0003] Currently, the adapter plugs on the market use sliding retractable prongs. Because European and British standard prongs are relatively long, sliding retractable prong products are relatively large in size, especially in height. When using the adapter plug, the center of gravity is too high and unstable, causing the charging process to be interrupted, which greatly reduces the user experience.

[0004] Therefore, it is necessary to design a multi-functional combination plug to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional combination plug that can reduce the size and height of the plug, improve safety and stability, and enhance the user experience.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0030] Figure 1 This is a structural schematic diagram of the multifunctional combination plug provided in this embodiment of the present invention in the first state (the plug body extends out of the base 1); Figure 2 This is a structural schematic diagram of the multi-functional combination plug provided in this embodiment of the present invention in its second state (the plug body is folded and stored in the base 1). Combined with... Figures 1 to 2As shown, this embodiment provides a multi-functional combination plug, including a base 1 and a plug body. The plug body includes at least a first plug 21 and a second plug 22, both of which are mounted on the base 1. Both the first plug 21 and the second plug 22 are foldable plugs. The base 1 has corresponding slots 11 and 12 for storing the first plug 21 and the second plug 22. The first plug 21 and the second plug 22 are stored on the base 1 by folding. Compared to the sliding storage method used in traditional adapter plugs, this effectively reduces the height dimension of the base 1 (see reference). Figure 1 (Double-headed arrow X).

[0031] In addition, the first slot 11 and the second slot 12 provided in this embodiment are connected, and there is a notch 2101 on the side of the first plug 21 facing the second slot 12. After the second plug 22 is folded into the second slot 12, part of the second plug 22 can be accommodated in the notch 2101, which further shortens the distance between the first plug 21 and the second plug 22. This further reduces the height and size required for the base 1, so that the multi-functional combination plug can effectively avoid the problem of unstable plugging with the socket due to the center of the base 1 being too high when in use, which greatly improves the safety and stability of the charging process and thus effectively increases the user's user experience.

[0032] Preferably, in this embodiment, the multi-functional combination plug integrates the European standard plug and the British standard plug commonly found on the market. The European standard plug is the first plug 21, which is a two-pronged cylindrical plug. The first plug 21 includes a plug block 211 and a first round-headed pin 212 and a second round-headed pin 213 arranged side-by-side on the plug block 211. The plug block 211 is pivotally hinged to the inner wall of the first slot 11, so that the plug block 211 can drive the first round-headed pin 212 and the second round-headed pin 213 to be housed in the first slot 11 or to be unscrewed from the first slot 11. It should be noted that the plug block 211 is provided with the notch 2101, and the notch 2101 is located between the first round head pin 212 and the second round head pin 213, so that after the second plug 22 is stored in the second slot 12, part of the second plug 22 can be limited and inserted into the notch 2101. Thus, the plug block 211 can also limit the second plug 22, which improves the storage stability of the second plug 22 to a certain extent.

[0033] The UK standard plug is the second plug 22. The second plug 22 is a triangular rectangular post plug, including a first square pin 221, a second square pin 222, and a third square pin 223. The first square pin 221, the second square pin 222, and the third square pin 223 are arranged in an isosceles triangle shape on the socket 1, and the length of the third square pin 223 is longer than the length of the first square pin 221 and the second square pin 222. It can be understood that when the second plug 22 is set as a UK standard plug, the third square pin 223 is the UK standard ground pin, and correspondingly, the first square pin 221 and the second square pin 222 are the live wire pin and the neutral wire pin, respectively. One end of the third-party plug 223 is hinged to the inner wall of the second slot 12. When the third-party plug 223 is folded and stored in the second slot 12, part of the third-party plug 223 can be accommodated in the notch 2101. This allows the multi-functional combination plug to be used in regions where both European and British plugs are the standard plugs. By shortening the distance between the European and British plugs, the size of the multi-functional combination plug in the height direction can be further reduced, thereby achieving the effect of enhanced charging safety and user experience.

[0034] More specifically, the second plug 22 provided in this embodiment also includes a first sliding member 224. The output end of the first sliding member 224 is connected to the first square plug 221 and the second square plug 222. The corresponding positions of the base body 1 are respectively provided with a third slot 13 and a fourth slot 14 for storing the first square plug 221 and the second square plug 222. The first sliding member 224 can drive the first square plug 221 and the second square plug 222 to slide and connect with the base body 1 through the third slot 13 and the fourth slot 14, so that when the British standard plug is needed, the user can push the first sliding member 224 to extend the first square plug 221 and the second square plug 222 upward from the inside of the base body 1. After use, pushing the first sliding member 224 in the opposite direction can retract the first sliding member 224 and the second sliding member 233 back into the base body 1, thereby facilitating use and storage.

[0035] For example, refer to Figure 3As shown, in this embodiment, the first sliding member 224 includes a first slider 2241, a first connecting handle 2242, and a first guide rod 2243. The first slider 2241 is connected to the first square-headed pin 221 and the second square-headed pin 222. One end of the first connecting handle 2242 is connected to the first slider 2241, and the other end extends outward through the first sliding groove 15 opened on the side wall of the base 1. The first guide rod 2243 is fixedly connected inside the base 1, and the length extension direction of the first guide rod 2243 is parallel to the sliding direction of the first square-headed pin 221 and the second square-headed pin 222. The first slider 2241 is slidably sleeved on the first guide rod 2243. With the above configuration, the user can operate the first connecting handle 2242 to drive the first slider 2241 to slide along the axis of the first guide rod 2243, so that the first square plug 221 and the second square plug 222 can extend smoothly from the base 1. The first guide rod 2243 can ensure that the first square plug 221 and the second square plug 222 will not wobble left and right after they are extended, thereby ensuring the safety and stability of the second plug 22 during charging.

[0036] Preferably, reference Figure 1 As shown, a push rod 2244 protrudes from the first slider 2241, and a fifth slot for storing the push rod 2244 is provided at the corresponding position at the bottom of the second slot 12. The push rod 2244 can extend out of the base 1 along with the first square head plug 221 and the second square head plug 222. At the same time, the push rod 2244 can lift the third third head plug 223 part housed in the notch 2101, so that the third third head plug 223 can extend out of the second slot 12. The user can then rotate the third third head plug 223 into place. At this time, the first square head plug 221, the second square head plug 222 and the third third head plug 223 simultaneously change to a posture perpendicular to the base 1, thereby facilitating the use of the second plug 22 and improving the efficiency of switching the use of the second plug 22.

[0037] Optionally, the plug body provided in this embodiment also includes a third plug 23, and a sixth slot 17 is provided at a corresponding position on the base 1. The third plug 23 and the sixth slot 17 are provided with an unfolded state and a retracted state. In the unfolded state, the third plug 23 can extend from the base 1, exposing the third plug 23 to the external environment for connection with the socket. In the retracted state, the third plug 23 can be housed in the sixth slot 17 to make the outer surface of the base 1 flat, making it convenient for users to carry. By providing the third plug 23, the multi-functional combination plug can be made more comprehensive in its functions and have a wider range of applications.

[0038] For example, in this embodiment, reference is made to Figure 1As shown, the third plug 23 is a US standard plug or an Australian standard plug. The third plug 23 adopts a two-prong flat plug and includes a pair of opposing first flat prongs 231 and second flat prongs 232. In this embodiment, a sixth slot 17 is provided on each side of the second slot 12. The first flat prongs 231 and the second flat prongs 232 correspond to a sixth slot 17, so that the first flat prongs 231 and the second flat prongs 232 are arranged on both sides of the third plug 223. Through the above configuration, it can further ensure that the base body 1 has a smaller size in the height direction, and at the same time, it can be used in regions where the plug standard is US standard, Australian standard, British standard and European standard, making it more widely usable, thus providing more convenient charging services for users traveling across countries or on business trips.

[0039] Specifically, the third plug 23 provided in this embodiment also includes a second sliding member 233. The output end of the second sliding member 233 is connected to the first flat plug 231 and the second flat plug 232, so that the second sliding member 233 can drive the first flat plug 231 and the second flat plug 232 to slide and connect with the base 1 through the sixth slot 17. When it is necessary to use a US standard plug or an Australian standard plug, the user can push the second sliding member 233 to extend the first flat plug and the second flat plug 232 upward from the inside of the base 1. After use, pushing the second sliding member 233 in the opposite direction can retract the third plug 23 back into the base 1, thereby facilitating the use and storage of the third plug 23.

[0040] More specifically, see reference Figure 3As shown, the second sliding member 233 includes a second slider 2331, a second connecting handle 2332, and a second guide rod 2333. The second slider 2331 is connected to the first flat head pin 231 and the second flat head pin 232. One end of the second connecting handle 2332 is connected to the second slider 2331, and the other end extends outward through the second sliding groove 16 opened on the side wall of the base 1. The second guide rod 2333 is fixedly connected inside the base 1, and the length extension direction of the second guide rod 2333 is parallel to the sliding direction of the first flat head pin 231 and the second flat head pin 232. The second slider 2331 is slidably sleeved on the second guide rod 2333. With the above configuration, the user can operate the second connecting handle 2332 to drive the second slider 2331 to slide along the axis of the second guide rod 2333, so that the first flat plug 231 and the second flat plug 232 can extend smoothly and easily from the base 1. The second guide rod 2333 ensures that the first flat plug 231 and the second flat plug 232 will not wobble from side to side after extension, thereby ensuring the safety and stability of the third plug 23 during charging. Preferably, in this embodiment, a second guide rod 2333 is provided on each side of the second slider 2331, which provides higher stability.
