Description

Technical Field

[0001] This invention relates to the field of travel adapters, and particularly to an interlocking travel adapter. Background Technology

[0002] Because plug standards differ from country to country, it's common for people's electrical appliances to be incompatible with local sockets when traveling internationally. To overcome these power barriers, travel adapters with integrated multi-standard movable prongs are needed. These adapters have multiple sets of movable prongs, requiring the extension of the desired prong and the retraction of the others. However, existing adapters often use a linear telescopic design for the movable prongs, where the prong length determines the thickness of the plug body, hindering efforts to reduce the plug's size when retracted. Furthermore, after extending the desired prong, it's crucial to ensure the other prongs remain stationary to prevent electric shock. Therefore, it's necessary to develop an interlocking travel adapter to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide an interlocking travel adapter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

The lower end of the first interlocking block is slidably connected to the spring plate mounting plate. The middle part of the first interlocking block is provided with a first mounting groove. The front and rear sides of the first interlocking block are respectively provided with a first limiting groove and a second limiting groove. The spring plate mounting plate is provided with a first stop block passing through the first mounting groove. The first spring corresponds to the first mounting groove and its front and rear ends are in contact with the first stop block and the inner wall of the first mounting groove, respectively.

[0007] Further description of the present invention: The second plug-in component includes a first rotating frame, a third plug, a fifth rotating post, and a second limiting boss. Two sets of the third plug are provided and fixed on the left and right sides of the first rotating frame. The fifth rotating post is fixed on the left and right sides of the front end of the first rotating frame. The front end of the first rotating frame is rotatably mounted on the plug housing through the fifth rotating post.

[0008] Further description of the invention: It also includes a third plug-in component. The middle part of the first rotating frame is provided with a second mounting cavity. The third plug-in component is located in the second mounting cavity. The third plug-in component includes a second rotating frame and a fourth plug. The rear ends of the second rotating frame can be rotatably mounted on the first rotating frame. The fourth plug is horizontally arranged. Two sets of the fourth plug are provided and fixed on the left and right sides of the second rotating frame respectively.

[0009] Further description of the present invention: The upper end of the plug housing is provided with a third limiting groove, the lower end of the third limiting groove is connected to the first mounting cavity, and the front end of the fourth plug corresponds to the third limiting groove.

[0010] Further description of the invention: The third plug-in component also includes a first locking block, which is fixed to the rear end of the second rotating frame. The first locking block is provided with a fastening channel and a fastening boss. The fastening channel vertically penetrates the second rotating frame, and the fastening boss is fixed to the inner wall of the rear end of the fastening channel. The plug housing is provided with a second locking block, which corresponds to the first mounting cavity and has a fastening groove at its lower end. After the first locking block is rotated forward by the second rotating frame, the second locking block corresponds to the fastening channel and the fastening boss corresponds to the fastening groove.

[0011] Further description of the invention: It also includes a second locking component, which includes a second interlocking block and a second spring. The second interlocking block is slidably connected to the spring plate mounting plate. The second interlocking block has a second mounting groove in its middle. The spring plate mounting plate has a second stop protruding into the second mounting groove. The second spring corresponds to the second mounting groove. The front and rear ends of the second spring contact the inner walls of the second stop and the second mounting groove, respectively. The left and right sides of the front end of the second interlocking block are provided with first driving blocks. The front end of the first driving block has a first arc-shaped surface above it. The rear end of the second pin is provided with a second driving block. The rear end of the second driving block has a second arc-shaped surface. The distance between the second arc-shaped surface and the rotation axis of the third rotating column gradually increases from bottom to top. The second arc-shaped surfaces of the two sets of second pins correspond to the two sets of first arc-shaped surfaces, respectively. The rear end of the second interlocking block is provided with a third driving block. The rear end surface of the third driving block contacts the front end surface of the second rotating frame.

[0012] Further description of the invention: The second locking component also includes a driving slider and a third locking block. The driving slider is slidably connected to the pin housing and can slide in the left and right direction. The driving slider is provided with a strip-shaped hole, which is obliquely arranged. The upper end of the second interlocking block is provided with a driving cylinder, which corresponds to the strip-shaped hole. The lower end of the third locking block is fixed to the driving slider. The upper end of the third locking block is provided with a third limiting boss on the side near the first pin. The side of the first pin corresponding to the third limiting boss is provided with a fourth limiting groove. After the second interlocking block moves backward, the third limiting boss corresponds to the fourth limiting groove.

[0013] The beneficial effects of this invention are as follows: During the process of flipping the first pin forward to a vertical state, the second rotating column rotates forward around the top of the first rotating column, thereby driving the fourth rotating column to rotate forward around the bottom of the third rotating column through the linkage plate, which in turn drives the second pins on both sides to also be in a vertical state, realizing linkage opening. The first pin can also be opened in linkage by flipping the second pin, with the same principle. The first plug-in component has three pins, which can be made into British standard pins. After the pins are flipped to a vertical state, the lower end of the pin is connected to the contact spring on the spring mounting plate, thereby electrically connecting to the socket component. The socket on the socket component is used to plug in the built-in electrical appliance, thereby realizing the transfer. The second plug-in component can also be flipped to a vertical state by the fifth rotating column. During the process of the second pin flipping backward, the first limiting boss is driven to flip forward, and the first locking component is pushed forward by pushing the first limiting groove. The inner wall of the rear side of the second limiting groove is close to the rear side of the second limiting boss, thereby restricting the second plug-in component from flipping forward. That is, the second plug-in component is not allowed to open when the first plug-in component is open, and vice versa. The advantages of this design are: the plug adopts a flip-fold design, which can reduce the size of the adapter plug; on the other hand, the plugs are interlocked, so when one standard plug is used, the other plugs cannot be opened, which can improve the safety of use.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 15 As shown, an interlocking travel adapter includes a socket component 1, a spring-loaded mounting plate 2, a pin housing 3, a first plug-in component 4, a second plug-in component 5, and a first locking component 6. The spring-loaded mounting plate 2 is fixed above the socket component 1 and has multiple sets of contact springs electrically connected to the socket component 1. The pin housing 3 is fixed above the socket component 1 and has a first mounting cavity 31 inside. The spring-loaded mounting plate 2 corresponds to the first mounting cavity 31. The first plug-in component 4 includes a first pin 41 and a second pin. 42. A first rotating column 43, a second rotating column 44, a third rotating column 45, a fourth rotating column 46, a linkage plate 47, and a first limiting boss 48. The first pin 41 and the second pin 42 are both horizontally arranged. The first rotating column 43 is fixed to the left and right sides of the front end of the first pin 41. The first pin 41 is rotatably mounted on the pin housing 3 via the first rotating column 43. The second rotating column 44 is fixed to the left and right sides of the front end of the first pin 41 and corresponds to the top of the first rotating column 43. Two sets of second pins 42 are provided and correspond to the first pin... On the left and right sides of the foot 41, the third rotating post 45 is fixed to the outer rear end of the second pin 42. The second pin 42 is rotatably mounted on the pin housing 3 via the third rotating post 45. The fourth rotating post 46 is fixed to the inner rear end of the second pin 42. The fourth rotating post 46 corresponds to the lower part of the third rotating post 45. The front and rear ends of the linkage plate 47 are rotatably mounted on the second rotating post 44 and the fourth rotating post 46, respectively. The first limiting boss 48 is fixed below the outer end of the third rotating post 45. The left and right sides of the second pin 42 component Each side is provided with a fifth rotating post 53 and a second limiting protrusion 54. The front end of the second pin 42 component is rotatably mounted on the pin housing 3 through the fifth rotating post 53. The second limiting protrusion 54 is fixed below the outer end of the fifth rotating post 53. The first locking component 6 is slidably connected to the spring plate 2 and can slide in the front-back direction. The first locking component 6 is provided with a first limiting groove 612 and a second limiting groove 613. The first limiting protrusion 48 and the second limiting protrusion 54 correspond to the first limiting groove 612 and the second limiting groove 613, respectively.

[0033] During the process of flipping the first pin 41 forward to a vertical position, the second rotating column 44 rotates forward around the top of the first rotating column 43, thereby driving the fourth rotating column 46 to rotate forward around the bottom of the third rotating column 45 via the linkage plate 47. This, in turn, drives the second pins 42 on both sides to also be in a vertical position, achieving a linkage opening. Alternatively, flipping the second pin 42 can also open the first pin 41 in a linkage manner, with the same principle. The first plug-in component 4 has three pins and can be made into British standard pins. After the pins are flipped to a vertical position, the lower end of the pin connects to the contact spring on the spring mounting plate 2, thereby... The adapter is electrically connected to the socket component 1, which has a socket for connecting its own electrical appliances, thus enabling the adapter to switch between devices. The second plug component 5 can also be flipped to a vertical position via the fifth rotating column 53. During the backward flipping of the second plug pin 42, the first limiting boss 48 is driven to flip forward, and the first locking component 6 is pushed forward by pushing the first limiting groove 612. The inner wall of the rear side of the second limiting groove 613 approaches the rear side of the second limiting boss 54, thereby restricting the forward flipping of the second plug component 5. That is, when the first plug component 4 is open, the second plug component 5 cannot be opened, and vice versa. The advantages of this design are: the plug pins adopt a flip-folding design, which reduces the size of the adapter plug; on the other hand, the plug pins are interlocked, so when one standard plug pin is used, the other plug pins cannot be opened, improving safety.

[0034] The first locking component 6 includes a first interlocking block 61 and a first spring 62. The lower end of the first interlocking block 61 is slidably connected to the spring plate mounting plate 2. The middle part of the first interlocking block 61 is provided with a first mounting groove 611. The front and rear sides of the first interlocking block 61 are respectively provided with a first limiting groove 612 and a second limiting groove 613. The spring plate mounting plate 2 is provided with a first stop 21 that passes through the first mounting groove 611. The first spring 62 corresponds to the first mounting groove 611 and its front and rear ends are in contact with the inner walls of the first stop 21 and the first mounting groove 611, respectively.

[0035] When the first plug-in component 4 is not in use, the first spring 62 drives the first interlock block 61 to move backward, so that the front inner wall of the first limiting groove 612 approaches the first limiting boss 48, preventing the second plug 42 from flipping. At the same time, it can also provide a certain degree of resistance during the process of manually flipping the first plug 41 or the second plug 42, enhancing the feel.

[0036] The second plug-in component 5 includes a first rotating frame 51, a third plug 52, a fifth rotating post 53, and a second limiting boss 54. Two sets of third plugs 52 are provided and fixed on the left and right sides of the first rotating frame 51. The fifth rotating post 53 is fixed on the left and right sides of the front end of the first rotating frame 51. The front end of the first rotating frame 51 is rotatably mounted on the plug housing 3 through the fifth rotating post 53.

[0037] The first rotating frame 51 is flipped to a vertical position by the fifth rotating column 53, and the third pin 52 rotates accordingly, so that the lower end of the third pin 52 is connected to the contact spring.

[0038] In this design, a third plug-in component 7 is also included. The middle part of the first rotating frame 51 is provided with a second mounting cavity. The third plug-in component 7 is located in the second mounting cavity. The third plug-in component 7 includes a second rotating frame 71 and a fourth plug 72. The rear ends of the second rotating frame 71 can be rotatably mounted on the first rotating frame 51. The fourth plug 72 is horizontally arranged. Two sets of the fourth plug 72 are provided and fixed on the left and right sides of the second rotating frame 71 respectively.

[0039] When the second plug-in component 5 is not in use, the second rotating bracket 71 rotates to a vertical position within the second mounting cavity, thereby connecting the lower end of the fourth pin 72 with the contact spring. The spacing between the fourth pins 72 is small, which can be configured as an American standard plug, while the spacing between the third pins 52 is large, which can be configured as a European standard plug.

[0040] The upper end of the plug housing 3 is provided with a third limiting groove 32, the lower end of the third limiting groove 32 is connected to the first mounting cavity 31, and the front end of the fourth plug 72 corresponds to the third limiting groove 32.

[0041] When the first rotating frame 51 is flipped to the vertical position, the second rotating frame 71 follows suit and rotates to the vertical position. At this time, the front end of the fourth pin 72 flips down from the third limiting groove 32 into the first mounting cavity 31. Due to the obstruction of the inner wall of the third limiting groove 32, the fourth pin 72 cannot be opened, thereby locking the third plug-in component 7 when the second plug-in component 5 is in use.

[0042] The third plug-in component 7 also includes a first locking block 73, which is fixed to the rear end of the second rotating frame 71. The first locking block 73 is provided with a fastening channel 731 and a fastening boss 732. The fastening channel 731 vertically penetrates the second rotating frame 71, and the fastening boss 732 is fixed to the inner wall of the rear end of the fastening channel 731. The plug housing 3 is provided with a second locking block 33, which corresponds to the first mounting cavity 31 and has a fastening groove 331 at its lower end. After the first locking block 73 is rotated forward by the second rotating frame 71, the second locking block 33 corresponds to the fastening channel 731 and the fastening boss 732 corresponds to the fastening groove 331.

[0043] When the second plug-in component 5 is not in use, the second rotating frame 71 is flipped to a vertical position, and the first locking block 73 is flipped downward around the rotating axis, so that the second locking block 33 is inserted into the fastening channel 731. After being flipped into place, the fastening boss 732 and the fastening groove 331 are fastened together, and the two are firmly connected. At this time, the second rotating frame 71 cannot move upward, thereby restricting the rotation of the first rotating frame 51, thus achieving the locking of the second plug-in component 5 when the third plug-in component 7 is in use.

[0044] This design also includes a second locking component 8, which includes a second interlocking block 81 and a second spring 82. The second interlocking block 81 is slidably connected to the spring plate 2. The second interlocking block 81 has a second mounting groove 811 in the middle. The spring plate 2 has a second stop 22 protruding into the second mounting groove 811. The second spring 82 corresponds to the second mounting groove 811. The front and rear ends of the second spring 82 contact the second stop 22 and the inner wall of the second mounting groove 811, respectively. The front left and right sides of the second interlocking block 81 are provided with first driving blocks. 812, a first arc-shaped surface 8121 is provided above the front end of the first drive block 812, a second drive block 421 is provided at the rear end of the second pin 42, a second arc-shaped surface 4211 is provided at the rear end of the second drive block 421, the distance between the second arc-shaped surface 4211 and the rotation axis of the third rotating column 45 gradually increases from bottom to top, the second arc-shaped surfaces 4211 of the two sets of second pins 42 correspond to the two sets of first arc-shaped surfaces 8121 respectively, a third drive block 813 is provided at the rear end of the second interlock block 81, and the rear end surface of the third drive block 813 contacts the front end surface of the second rotating frame 71.

[0045] When the second pin 42 is flipped to a vertical position, the second drive block 421 rotates downward around the rear side of the rotation axis, and the second arc-shaped surface 4211 contacts the first arc-shaped surface 8121. As the distance between the second arc-shaped surface 4211 and the rotation axis of the third rotating column 45 gradually increases, the first arc-shaped surface 8121 is pushed backward, thereby pushing the third drive block 813 backward. The rear end face of the third drive block 813 contacts the front end face of the second rotating frame 71, thereby restricting the rotation of the second rotating frame 71 and locking the third plug-in component 7 when the first plug-in component 4 is in use. Similarly, when the third plug-in component 7 is in use, the second rotating frame 71 pushes the second interlock block 81 forward, so that the first arc-shaped surface 8121 and the second arc-shaped surface 4211 contact each other, suppressing the rotation of the second pin 42 and locking the first plug-in component 4. When the plug is not in use, the second interlock block 81 moves to the rear under the action of the second spring 82, thereby restricting the flipping of the fourth pin 72. It also provides a certain degree of resistance during the manual flipping of the third pin 52 or the fourth pin 72, enhancing the feel.

[0046] The second locking component 8 also includes a drive slider 83 and a third locking block 84. The drive slider 83 is slidably connected to the pin housing 3 and can slide in the left and right direction. The drive slider 83 is provided with a strip hole 831, which is obliquely arranged. The upper end of the second interlocking block 81 is provided with a drive cylinder 814, which corresponds to the strip hole 831. The lower end of the third locking block 84 is fixed on the drive slider 83. The upper end of the third locking block 84 is provided with a third limiting boss 841 on the side near the first pin 41. The first pin 41 is provided with a fourth limiting groove 411 on the side corresponding to the third limiting boss 841. After the second interlocking block 81 moves backward, the third limiting boss 841 corresponds to the fourth limiting groove 411.

[0047] When the third plug-in component 7 is in use, the second rotating frame 71 pushes the second interlock block 81 forward, thereby causing the driving cylinder 814 to move forward, and the driving slider 83 slides through the obliquely set strip groove, so that the third limiting boss 841 on the third locking block 84 is inserted into the fourth limiting groove 411 of the first plug 41, thereby locking the first plug 41 and further strengthening the locking of the first plug-in component 4.

[0048] The socket component 1 can be equipped with various standard connection sockets 11 as needed for ease of use.

[0049] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
