Description

Technical Field:

[0001] The present invention relates to the technical field of power plug converters, and particularly to a rotary multi-specification plug converter. Background Art:

[0002] A Chinese invention with the patent publication number CN1322638C discloses a power plug. Its design uses three movable limiting blades. When any one of the four plugs is pushed to the effective power-taking position, the limiting blades will be squeezed into the downward path of the push-button linkages of the other three plugs, thereby fixing the other three plugs in the ineffective position. This design realizes the function of automatically locking the remaining plugs when one plug is in use with a simple mechanism, greatly improving the safety of use; however, this design has a limitation, that is, the position of the power output socket is fixed and cannot be flexibly adjusted according to the specific usage scenario, restricting its applicability in different environments.

[0003] In view of this, the inventor of the present invention proposes the following technical solutions. Summary of the Invention:

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a rotary multi-specification plug converter.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: The rotary multi-specification plug converter includes an input component and an output component, both of which have a housing; two groups of plugs are provided in the first housing of the input component and are pushed out in different directions; the output component is provided with power socket holes for AC or DC; the two groups of plugs are connected to push buttons outside the first housing through extension arms, and the push buttons can be horizontally pushed to push the first group of plugs to the left and the second group of plugs to the right respectively, so that the conductive pins of the first group of plugs or the second group of plugs extend out of the first housing; holes matching the conductive pins are provided at both the left and right ends of the first housing; the first housing of the input component is provided with a protruding rotating shaft, which is located below the first housing and the axis direction thereof is perpendicular to the sliding direction of the two groups of plugs; a through hole is provided in the rotating shaft, and a conductive connecting rod for the live wire and the neutral wire is accommodated in the through hole, and this conductive connecting rod is responsible for transmitting the power of the input component to the output component; a shaft hole is provided above the second housing of the output component, and its size and position correspond to those of the rotating shaft, and the input component and the output component achieve relative rotation through the coupling of the rotating shaft and the shaft hole. When the first group of plugs or the second group of plugs of the input component are inserted into a wall socket to take power, the position and orientation of the power socket holes of the output component can be changed by rotating the output component.

[0006] Furthermore, in the above technical solution, the rotating shaft of the input component is arranged at a position slightly to the left or right of the center below the first housing; the size and position of the shaft hole on the second housing of the output component correspond to the rotating shaft of the input component; the input component and the output component are coupled through the rotating shaft and the shaft hole, so that the left and right ends of the original positions of the first housing and the second housing are aligned and can rotate relative to each other; since the rotation center is biased towards the left end of the first housing, when the input component rotates 180 degrees relative to the output component, the right end of the first housing of the input component will rotate to the outside of the left end of the second housing of the output component and form a protruding end; when the conductive pins of the second group of plugs are pushed out from this protruding end and inserted into the European standard socket, the protruding end can extend into the concave part of the European standard socket.

[0007] Furthermore, in the above technical solution, the first live wire conductive pin of the first group of plugs and the second live wire conductive pin of the second group of plugs form a live wire conductive pin module, and the first neutral wire conductive pin of the first group of plugs and the second neutral wire conductive pin of the second group of plugs form a neutral wire conductive pin module; the conductive pins of the two groups of plugs are arranged in opposite directions.

[0008] Furthermore, in the above technical solution, sliding grooves are provided at the centers on both sides of the first housing of the input component, and the extending arms of the push buttons pass through the sliding grooves and are respectively connected to the live wire conductive pin module and the neutral wire conductive pin module; by horizontally moving the push buttons, the first group of plugs and the second group of plugs are driven to slide left and right.

[0009] Furthermore, in the above technical solution, guiding grooves are provided at the centers of both the live wire conductive pin module and the neutral wire conductive pin module, and positioning teeth are provided on the extending arms of the push buttons. The positioning teeth can extend into the guiding grooves and move therein; limiting bosses that cooperate with the positioning teeth are provided at the inner edges of the sliding grooves of the input component; when the two sides of the push buttons are pressed, the positioning teeth of the extending arms are disengaged from the limitation of the limiting bosses, driving the two groups of plugs to slide.

[0010] Furthermore, in the above technical solution, an insulating bracket is provided at the center of both the live wire conductive pin module and the neutral wire conductive pin module. The insulating bracket connects the live wire conductive pin module and the neutral wire conductive pin module into one body and is provided with a guiding groove. The guiding groove accommodates one or more return springs; the positioning teeth on the extending arms are inserted into the guiding grooves and contact the return springs. The elastic force of the return springs pushes the positioning teeth of the extending arms to press against the sliding grooves of the input component, and the positioning teeth are restricted by the limiting bosses.

[0011] Furthermore, in the above technical solution, a set of conductive rails are provided respectively below the live wire conductive pin module and the neutral wire conductive pin module. Each of the two ends of the conductive rail has a hem to maintain the contact between the live wire and neutral wire conductive pin modules and the conductive rail. Two parallel conductive discs are provided at the end of the rotating shaft. The conductive discs are fixed to the rotating shaft and are located inside the output assembly. The rotation direction of the conductive discs is perpendicular to the axis of the rotating shaft and rotates synchronously with the rotation of the input assembly. The conductive connecting rod connects the conductive rail and the conductive disc. A conductive clamping piece is provided inside the output assembly, and the conductive clamping piece contacts the conductive disc. When the input assembly and the output assembly rotate relative to each other, the conductive clamping piece and the conductive disc always maintain contact.

[0012] Furthermore, in the above technical solution, a hole is provided in the push button, and a button that can move up and down is installed in the hole. A stop block is provided between the live wire conductive pin module and the neutral wire conductive pin module. The stop block can move up and down, and a return spring is provided inside, and inclined surfaces are provided on both sides. The upper end head of the stop block protrudes outside the housing of the input assembly and can be pressed down by the button. Protrusions are provided on the sides of the live wire conductive pin module and the neutral wire conductive pin module, and the protrusions cooperate with the inclined surfaces of the stop block. When the push button pushes the live wire conductive pin module and the neutral wire conductive pin module to move left or right, the protrusions slide along the inclined surfaces of the stop block and push the stop block downward. When the protrusions slide past the inclined surfaces, the stop block rises under the action of the return spring and restricts the protrusions to a specific position, thereby locking the positions of the live wire conductive pin module and the neutral wire conductive pin module and fixing the corresponding conductive pins at the effective power connection positions. By pressing the button, the upper end head of the stop block is pressed downward by the button, and the protrusions are released from the restriction of the stop block, thereby releasing the fixed state of the live wire conductive pin module and the neutral wire conductive pin module.

[0013] Furthermore, in the above technical solution, an extension arm is provided at the lower end of the push button, and the extension arm penetrates through the upper end of the first housing of the input assembly. A convex block with a spring upper groove is provided at the end of the extension arm, and the spring upper groove is used to accommodate the return spring. A connecting block is provided at the center of the live wire conductive pin module and the neutral wire conductive pin module, and the connecting block is used to connect the live wire conductive pin module and the neutral wire conductive pin module into one body. A spring lower groove is provided at the center of the connecting block, and the convex block is slidably nested in the spring lower groove. A card slot for restricting the position of the convex block is provided at the upper end inside the first housing of the input assembly. When the push button is pressed, the convex block disengages from the card slot, and the push button can drive the live wire conductive pin module and the neutral wire conductive pin module to move in the left-right direction.

[0014] Furthermore, in the above technical solution, an independent British ground plug is further included. The British ground plug has a ground pin, and extension feet extending downward are provided on both sides of the British ground plug. An iron sheet is provided in the middle section of the extension feet, a limiting hole is provided at the end of the extension feet, and a clamping convex is also provided in the middle section of the extension feet; a groove matching the size of the clamping convex is provided above the first housing of the input component, and the clamping convex of the British ground plug is inserted and stands above the first housing; when the second set of plugs is pushed out of the first housing, the limiting hole can be penetrated by the conductive pins of the second set of plugs, so that the British ground plug is fixed on the second set of plugs.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0016] 1. Since the input component and the output component can rotate relative to each other, when the first set of plugs or the second set of plugs of the input component are inserted into a wall socket to obtain power, the position and orientation of the power socket holes of the output component can be changed by the rotation of the output component relative to the input component, so that it is convenient for plugs to be inserted in different directions, improving the convenience and compatibility of use, and is particularly suitable for occasions such as tourism.

[0017] 2. The push button in the present invention can be pushed horizontally, and the first set of plugs can be pushed to the left and the second set of plugs can be pushed to the right respectively, so that the conductive pins of the first set of plugs or the second set of plugs extend out of the first housing, adapting to the socket specifications of various countries, simplifying the use and improving the flexibility.

[0018] 3. Since the rotation center is biased towards the left end of the first housing, when the input component rotates relative to the output component, the right end of the housing of the input component will turn to the outside of the left end of the housing of the output component and form a protruding end; when the conductive pins of the second set of plugs are pushed out from this protruding end and inserted into a European standard socket, this protruding end can extend into the concave part of the European standard socket, thereby ensuring the adaptation of the first housing to the European standard socket and ensuring the stability after docking.

[0035] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0036] See Figures 1-15 shown, for a rotary multi-specification plug converter, including an input component 100 and an output component 500, both of which have a housing; two groups of plugs are provided inside the first housing 3 of the input component 100, and are respectively pushed out in different directions. Among them, the two groups of plugs are fixed together to form a whole; when the first group of plugs 1 is pushed out to the left, the second group of plugs 2 is retracted to the left. Conversely, when the second group of plugs 2 is pushed out to the right, the first group of plugs 1 is retracted to the right, that is, only any one of the two groups of plugs can be used. The output component 500 is provided with AC or DC power socket holes 52 for other different types of plugs to be inserted to achieve power-on. As in Figures 1-4Among them, the power socket hole 52 is an AC power socket hole, and in Figures 5-6 Among them, the power socket hole 52 is a DC power socket hole.

[0037] Socket specifications and installation directions vary in different countries. The present invention has made the following improvements: As shown in combination with Figures 1-6 Two sets of plugs are connected to the push button 4 outside the first housing 3 through the extension arm 41. The push button 4 can be pushed horizontally to push the first set of plugs 1 to the left and the second set of plugs 2 to the right respectively, so that the conductive pins of the first set of plugs 1 or the second set of plugs 2 extend out of the first housing 3, adapting to the socket specifications of various countries, simplifying the use and enhancing the flexibility.

[0038] As shown in combination with Figures 1-6 Both the left and right ends of the first housing 3 are provided with holes 31 that cooperate with the conductive pins; the first housing 3 of the input component 100 is provided with a protruding rotating shaft 32, which is located below the first housing 3, and the axis direction thereof is perpendicular to the sliding direction of the two sets of plugs; a through hole 321 is provided in the rotating shaft 32, and the conductive connecting rod 33 for the live wire and the neutral wire is accommodated by the through hole 321. The conductive connecting rod 33 is responsible for transmitting the power of the input component 100 to the output component 500; a shaft hole 51 is provided above the second housing 5 of the output component 500, and the size and position of the shaft hole 51 correspond to those of the rotating shaft 32, and the input component 100 and the output component 500 are relatively rotated through the coupling of the rotating shaft 32 and the shaft hole 51, that is, a rotatable assembly structure is formed. When the first set of plugs 1 or the second set of plugs 2 of the input component 100 are inserted into a wall socket to obtain power, the position and orientation of the power socket hole 52 of the output component 500 can be changed by the rotation of the output component 500, so that it is convenient for the plug to be inserted in different directions, improving the convenience and compatibility of use, and is particularly suitable for occasions such as traveling.

[0039] As shown in combination with Figures 1-6As shown, the rotating shaft 32 of the input component 100 is arranged at a position slightly to the left or right of the center below the first housing 3; the size and position of the shaft hole 51 on the second housing 5 of the output component 500 correspond to the rotating shaft 32 of the input component 100; the input component 100 and the output component 500 are coupled through the rotating shaft 32 and the shaft hole 51, so that the left and right ends of the original positions of the first housing 3 and the second housing 5 are aligned and can rotate relative to each other; since the rotation center is biased towards the left end of the first housing 3, when the input component 100 rotates 180 degrees relative to the output component 500, the right end of the first housing of the input component 100 will rotate outside the left end of the second housing of the output component 500 and form a protruding end; alternatively, since the rotation center is biased towards the right end of the first housing 3, when the input component 100 rotates 180 degrees relative to the output component 500, the left end of the first housing 3 of the input component 100 will rotate outside the right end of the second housing 5 of the output component 500 and form a protruding end 101; when the conductive pins of the second group of plugs 2 are pushed out from this protruding end and inserted into the European standard socket, the protruding end 101 can extend into the concave part of the European standard socket, thereby ensuring the adaptation of the first housing 3 to the European standard socket and further ensuring the stability after docking. Among them, the European standard socket of model CEE7 / 3 or CEE7 / 5 is provided with a concave part (i.e., a groove) on the surface of the jack, which is used for mating and docking with the protruding end 101 to achieve a stable connection.

[0040] Combined with Figure 7 As shown, the first live wire conductive pin 11 of the first group of plugs 1 and the second live wire conductive pin 21 of the second group of plugs 2 form a live wire conductive pin module 10, and the first neutral wire conductive pin 12 of the first group of plugs 1 and the second neutral wire conductive pin 22 of the second group of plugs 2 form a neutral wire conductive pin module 20; the conductive pins of the two groups of plugs are arranged in opposite directions; it is worth mentioning that the Figure 7 shown first live wire conductive pin 11 and first neutral wire conductive pin 12 can be mutually replaced, and correspondingly, the second live wire conductive pin 21 and the second neutral wire conductive pin 22 can be mutually replaced.

[0041] On both sides of the center of the first housing 3 of the input component 100, there are sliding grooves 34. The extension arms 41 of the push buttons 4 pass through the sliding grooves 34 and are respectively connected to the live wire conductive pin module 10 and the neutral wire conductive pin module 20; by horizontally moving the push buttons 4, the extension arms 41 of the push buttons 4 can stably move horizontally in the sliding grooves 34, thereby driving the first group of plugs 1 and the second group of plugs 2 to slide left and right, that is, driving the first group of plugs 1 and the second group of plugs 2 to slide synchronously to the left or right.

[0042] Combined with Figures 7-8As shown, a guiding groove 301 is provided at the center of both the live wire conductive pin module 10 and the neutral wire conductive pin module 20. The extending arm 41 of the push button 4 is provided with positioning teeth 411, and the positioning teeth 411 can extend into the guiding groove 301 and move therein. Correspondingly, a limiting boss 341 that cooperates with the positioning teeth 411 is provided at the inner edge of the sliding groove 34 of the input assembly 100. When the two sides of the push button 4 are pressed, the positioning teeth 411 of the extending arm 41 are disengaged from the restriction of the limiting boss 341, driving the two groups of plugs to slide. Similarly, when the two sides of the push button 4 are not pressed, the positioning teeth 411 of the extending arm 41 are engaged with the limiting boss 341 to achieve positioning, thereby ensuring that the two groups of plugs are stably positioned inside the first housing 3, preventing the two groups of plugs from moving accidentally, and thus ensuring the quality of the entire plug converter.

[0043] As shown in combination with Figures 7-9 As shown, an insulating bracket 30 is provided at the center of the live wire conductive pin module 10 and the neutral wire conductive pin module 20. The insulating bracket 30 connects the live wire conductive pin module 10 and the neutral wire conductive pin module 20 into one body, and the insulating bracket 30 is provided with the guiding groove 301. The guiding groove 301 accommodates one or more return springs 302. The positioning teeth 411 on the extending arm 41 are inserted into the guiding groove 301 and contact the return springs 302. The elastic force of the return springs 302 pushes the positioning teeth 411 of the extending arm 41 to press against the sliding groove 34 of the input assembly 100, and the positioning teeth 411 are restricted by the limiting boss 341, so that the live wire conductive pin module 10 and the neutral wire conductive pin module 20 are limited inside the first housing 3, preventing them from being accidentally pushed and moving.

[0044] As shown in combination with Figures 10-11 As shown, a set of conductive rails 40 are provided below each of the live wire conductive pin module 10 and the neutral wire conductive pin module 20. Each of the two ends of the conductive rail 40 has a hem 401 to maintain the contact between the live and neutral wire conductive pin modules and the conductive rail 40, that is, the live wire conductive pin module 10 forms a stable contact with a set of conductive rails 40, and the neutral wire conductive pin module 20 forms a stable contact with the other set of conductive rails 40. Two parallel conductive disks 35 are provided at the end of the rotating shaft 32. The conductive disks 35 are fixed to the rotating shaft 32 and are located inside the output assembly 500. The rotation direction of the conductive disks 35 is perpendicular to the axis of the rotating shaft 32 and rotates synchronously with the rotation of the input assembly 100. The conductive connecting rod 33 connects the conductive rail 40 and the conductive disk 35. A conductive clamping piece 501 is provided inside the output assembly 500, and the conductive clamping piece 501 contacts the conductive disk 35. When the input assembly 100 and the output assembly 500 rotate relative to each other, the conductive clamping piece 501 and the conductive disk 35 always remain in contact, that is, they are always in a conducting state. There are two conductive clamping pieces 501, two conductive disks 35, two conductive rails 40, and two conductive connecting rods 33. Among them, one conductive clamping piece 501, one conductive disk 35, one conductive rail 40, and one conductive connecting rod 33 are connected in sequence to conduct electricity.

[0045] As shown in the figure, the first live wire conductive pin 11 and the first neutral wire conductive pin 12 of the first set of plugs 1 are both flat-shaped, and a threaded conductive rotating shaft 102 is provided at the root; the second live wire conductive pin 21 and the second neutral wire conductive pin 22 of the second set of plugs 2 are both circular, and a conductive shaft hole 202 is provided at the root, and the conductive shaft hole 202 is also provided with a thread matching the conductive rotating shaft 102. The conductive rotating shaft 102 and the conductive shaft hole 202 are mutually coupled and rotatable. By adjusting the relative angle between the first live wire conductive pin 11 and the first neutral wire conductive pin 12 in the first set of plugs 1, the first set of plugs 1 can be adapted to American sockets and Australian sockets, making it more convenient to use. Figure 12 In another embodiment, as shown in the figure, a hole 42 is provided on the push button 4, and a button 43 that can move up and down is installed in the hole 42; a stopper 6 is provided between the live wire conductive pin module 10 and the neutral wire conductive pin module 20. The stopper 6 can move up and down, a return spring 302 is provided inside, and inclined surfaces 61 are provided on both sides; the upper end head 62 of the stopper 6 protrudes outside the housing of the input assembly 100 and can be pressed down by the button 43; protrusions 103 are provided on the sides of the live wire conductive pin module 10 and the neutral wire conductive pin module 20, and the protrusions 103 cooperate with the inclined surfaces 61 of the stopper 6; when the push button 4 pushes the live wire conductive pin module 10 and the neutral wire conductive pin module 20 to move to the left end or the right end, the protrusions 103 slide along the inclined surfaces 61 of the stopper 6 and push the stopper 6 downward. When the protrusions 103 slide past the inclined surfaces 61, the stopper 6 rises under the action of the return spring 302, restricting the protrusions 103 to a specific position, thereby locking the positions of the live wire conductive pin module 10 and the neutral wire conductive pin module 20, and fixing the corresponding conductive pins at the effective power connection positions; by pressing the button 43, the upper end head 62 of the stopper 6 is pressed downward by the button 43, and the protrusions 103 are released from the restriction of the stopper 6, thereby releasing the fixed state of the live wire conductive pin module and the neutral wire conductive pin module.

[0046] In another embodiment, as shown in the figure, Figures 13-14 As shown in the figure, a hole 42 is provided on the push button 4, and a button 43 that can move up and down is installed in the hole 42; a stopper 6 is provided between the live wire conductive pin module 10 and the neutral wire conductive pin module 20. The stopper 6 can move up and down, a return spring 302 is provided inside, and inclined surfaces 61 are provided on both sides; the upper end head 62 of the stopper 6 protrudes outside the housing of the input assembly 100 and can be pressed down by the button 43; protrusions 103 are provided on the sides of the live wire conductive pin module 10 and the neutral wire conductive pin module 20, and the protrusions 103 cooperate with the inclined surfaces 61 of the stopper 6; when the push button 4 pushes the live wire conductive pin module 10 and the neutral wire conductive pin module 20 to move to the left end or the right end, the protrusions 103 slide along the inclined surfaces 61 of the stopper 6 and push the stopper 6 downward. When the protrusions 103 slide past the inclined surfaces 61, the stopper 6 rises under the action of the return spring 302, restricting the protrusions 103 to a specific position, thereby locking the positions of the live wire conductive pin module 10 and the neutral wire conductive pin module 20, and fixing the corresponding conductive pins at the effective power connection positions; by pressing the button 43, the upper end head 62 of the stopper 6 is pressed downward by the button 43, and the protrusions 103 are released from the restriction of the stopper 6, thereby releasing the fixed state of the live wire conductive pin module and the neutral wire conductive pin module.

[0047] In another embodiment, the following is another structure of the push button 4, specifically:

[0048] As shown in the figure, Figure 15As shown, a extension arm 41 is provided at the lower end of the push button 4, and the extension arm 41 penetrates through the upper end of the first housing 3 of the input assembly 100; a bump 44 with a spring upper groove is provided at the end of the central extension arm 41, and the spring upper groove is used to accommodate the return spring 45; a connecting block 104 is provided in the center of the live wire conductive pin module 10 and the neutral wire conductive pin module 20, and the connecting block 104 is used to connect the live wire conductive pin module 10 and the neutral wire conductive pin module 20 into one body. A spring lower groove 105 is provided in the center of the connecting block 104. The bump 44 is slidably nested in the spring lower groove 105, and the lower end of the return spring 45 contacts the bottom of the spring lower groove 105 to ensure that the return spring 45 is confined in the spring upper groove of the bump 44, thereby providing elastic force for the bump 44. A card slot 36 for restricting the position of the bump 44 is provided at the upper end inside the first housing 3 of the input assembly 100. The bump 44 is engaged with the card slot 36, thereby ensuring that the live wire conductive pin module 10 and the neutral wire conductive pin module 20 are locked in the first housing 3 to prevent the live wire conductive pin module 10 and the neutral wire conductive pin module 20 from moving; when the push button 4 is pressed, the bump 44 disengages from the card slot 36, and the push button 4 can drive the live wire conductive pin module 10 and the neutral wire conductive pin module 20 to move in the left-right direction.

[0049] In another embodiment, in combination with Figure 16 As shown, the present invention further includes an independent British ground plug 7. The British ground plug 7 has a ground pin 71, and extension feet 72 extending downward are provided on both sides of the British ground plug 71. An iron sheet 73 is provided in the middle section of the extension feet 72, a limit hole 721 is provided at the end of the extension feet 72, and a clamping projection 722 is also provided in the middle section of the extension feet 72; a groove 303 matching the size of the clamping projection 722 is provided above the first housing 3 of the input assembly 100. Among them, the number of the clamping projections 722 and the grooves 303 is two. The clamping projection 722 of the British ground plug 7 is inserted and stands above the first housing 3; when the second group of plugs 2 is pushed out of the first housing 3, the limit hole 721 can be penetrated by the conductive pins of the second group of plugs 2, so that the British ground plug 7 is fixed on the second group of plugs 2. Its assembly is extremely simple, and it can ensure the stability of the assembly structure, and can also meet the plug-in use of different types of sockets (such as UK sockets).

[0050] A magnet 502 can also be provided on the second housing 5. After the British ground plug 7 is inserted into the power socket hole 52 on the second housing 5, the iron sheet 73 on the British ground plug 7 is adsorbed and fixed to ensure that the British ground plug 7 is stably inserted on the second housing 5 to achieve the storage function.

[0051] Of course, the above are only specific embodiments of the present invention and do not limit the scope of implementation of the present invention. For example, each country has a defined direction for the positions of the live wire and the neutral wire of the plug pin, which may be opposite to that of this embodiment; any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention shall be included within the scope of the patent application of the present invention.
