Description
A rotary multi-specification plug adapter Technical Field
[0001] This invention relates to the field of power plug converter technology, and specifically to a rotary multi-specification plug converter. Background Technology
[0002] Chinese invention patent CN1322638C discloses a power plug with three movable limiting blades. When any one of the four plugs is pushed to the active power position, the limiting blades are pressed into the pull-down path of the push button linkages of the other three plugs, thereby fixing the other three plugs in the inactive position. This design achieves the function of automatically locking the other plugs when one plug is in use with a simple mechanism, greatly improving the safety of use. Technical issues
[0003] However, this design has a limitation: the position of the power output socket is fixed and cannot be flexibly adjusted according to specific usage scenarios, which limits its applicability in different environments. Technical solutions
[0004] In view of this, the inventor proposes the following technical solution. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotary multi-specification plug adapter.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The rotary multi-specification plug adapter includes an input component and an output component, both of which have a housing; the first housing of the input component has two sets of plugs, which extend in different directions; the output component has an AC or DC power socket hole; the two sets of plugs are connected to a push button outside the first housing via an extension arm, the push button can be pushed horizontally to push the first set of plugs to the left and the second set of plugs to the right, respectively, so that the conductive pins of the first or second set of plugs extend out of the first housing; both ends of the first housing have holes that mate with the conductive pins; the first... One housing has a protruding pivot located below the first housing, with its axis perpendicular to the sliding direction of the two sets of plugs. The pivot has a through hole that accommodates a conductive connecting rod for the live wire and neutral wire, which transmits power from the input component to the output component. A shaft hole is located above the second housing of the output component, its size and position corresponding to the pivot. The input and output components rotate relative to each other via the coupling of the pivot and the shaft hole. When the first or second set of plugs of the input component is inserted into a wall socket to draw power, the rotation of the output component changes the position and orientation of the power socket hole.
[0007] Furthermore, in the above technical solution, the pivot of the input component is located 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 pivot of the input component; the input component and the output component are coupled through the pivot and shaft hole, so that the original left and right ends 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 left end of the second housing of the output component and form a protruding end; when the conductive pin of the second plug is pushed out from this protruding end and inserted into the European standard socket, the protruding end can extend into the recess of the European standard socket.
[0008] Furthermore, in the above technical solution, the first live wire conductive pin of the first plug and the second live wire conductive pin of the second plug constitute a live wire conductive pin module, and the first neutral wire conductive pin of the first plug and the second neutral wire conductive pin of the second plug constitute a neutral wire conductive pin module; the conductive pins of the two plugs are arranged in opposite directions.
[0009] Furthermore, in the above technical solution, the input component has a sliding groove in the center of both sides of the first housing. The extension arm of the push button passes through the sliding groove and is connected to the fire wire conductive pin module and the center wire conductive pin module respectively. The push button moves horizontally, causing the first set of plugs and the second set of plugs to slide left and right.
[0010] Furthermore, in the above technical solution, both the fire wire conductive pin module and the center wire conductive pin module are provided with guide grooves in the center, and the extension arm of the push button is provided with positioning teeth. The positioning teeth can extend into the guide groove and move therein. The inner edge of the slide groove of the input component is provided with a limiting boss that cooperates with the positioning teeth. When the push button is pressed on both sides, the positioning teeth of the extension arm disengage from the limiting boss, causing the two sets of plugs to slide.
[0011] Furthermore, in the above technical solution, an insulating bracket is provided in the center of the fire wire conductive needle module and the center wire conductive needle module. The insulating bracket connects the fire wire conductive needle module and the center wire conductive needle module into one unit and is provided with a guide groove. The guide groove accommodates one or more return springs. The positioning teeth on the extension arm are inserted into the guide groove and contact the return springs. The elastic force of the return springs pushes the positioning teeth of the extension arm to push against the slide groove of the input component and makes the positioning teeth restricted by the limiting boss.
[0012] Furthermore, in the above technical solution, each of the fire wire conductive needle module and the center wire conductive needle module is provided with a set of conductive rails below it. Each of the two ends of the conductive rails has a folded edge to maintain contact between the fire and center wire conductive needle modules and the conductive rails. The end of the rotating shaft is provided with two parallel conductive disks, which are fixed to the rotating shaft and located inside the output component. The rotation direction of the conductive disks is perpendicular to the axis of the rotating shaft and rotates synchronously with the rotation of the input component. The conductive connecting rod connects the conductive rails and the conductive disks. A conductive clamping piece is provided inside the output component, which contacts the conductive disks. When the input component and the output component rotate relative to each other, the conductive clamping piece and the conductive disks always remain in contact.
[0013] Furthermore, in the above technical solution, the push button has a hole with a button that can move up and down inside; a stop block is provided between the live wire conductive needle module and the neutral wire conductive needle module. The stop block can move up and down, has a return spring inside, and has inclined surfaces on both sides; the upper end of the stop block protrudes outside the input component housing and can be pressed down by the button; both the live wire conductive needle module and the neutral wire conductive needle module have protrusions on their sides, which cooperate with the inclined surfaces of the stop block; when the push button pushes the live wire conductive needle module and the neutral wire conductive needle module to the left or right, the protrusion slides along the inclined surface of the stop block and pushes the stop block downward. After the protrusion slides past the inclined surface, the stop block rises under the action of the return spring, restricting the protrusion to a specific position, thereby locking the position of the live wire conductive needle module and the neutral wire conductive needle module, and fixing the corresponding conductive needle in the effective contact position; by pressing the button, the upper end of the stop block is pressed down by the button, the protrusion is released from the restriction of the stop block, thereby releasing the fixed state of the live wire conductive needle module and the neutral wire conductive needle module.
[0014] Furthermore, in the above technical solution, the lower end of the push button is provided with an extension arm, which extends through the upper end of the first housing of the input component; the end of the extension arm is provided with a protrusion with a spring groove, which is used to accommodate a return spring; a connecting block is provided in the center of the fire wire conductive needle module and the center wire conductive needle module, which is used to connect the fire wire conductive needle module and the center wire conductive needle module into one unit, and a spring groove is provided in the center of the connecting block, in which the protrusion is slidably nested; the upper end of the inside of the first housing of the input component is provided with a slot for limiting the position of the protrusion; when the push button is pressed, the protrusion disengages from the slot, and the push button can drive the fire wire conductive needle module and the center wire conductive needle module to move in the left and right direction.
[0015] Furthermore, the above technical solution also includes an independent British grounding plug, which has a grounding pin and downward-extending extension legs on both sides. The extension legs have a metal plate in the middle section and a limiting hole at the end. The extension legs also have a locking protrusion in the middle section. The first housing of the input component has a groove on its upper part that matches the size of the locking protrusion. The locking protrusion of the British grounding plug is inserted into and stands on the upper part of the first housing. When the second set of plugs is pushed out of the first housing, the limiting hole can be passed through by the conductive pin of the second set of plugs, so that the British grounding plug is fixed on the second set of plugs. Beneficial effects
[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0017] 1. Since the input component and the output component can rotate relative to each other, when the first or second set of plugs of the input component is inserted into the wall socket to draw power, the position and orientation of the power socket hole of the output component can be changed by rotating the output component relative to the input component. This allows the plug to be inserted in different directions, improving the convenience and compatibility of use, and is especially suitable for travel and other occasions.
[0018] 2. The push button in this invention can be pushed horizontally, which can push the first set of plugs to the left and the second set of plugs 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 use and improving flexibility.
[0019] 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 input component housing will rotate to the left end of the output component housing and form a protruding end; when the conductive pin of the second plug is pushed out from this protruding end and inserted into the European standard socket, the protruding end can extend into the recess of the European standard socket, thereby ensuring that the first housing is compatible with the European standard socket and thus ensuring the stability after docking.

[0036] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0037] As shown in Figure 1-15, a rotary multi-specification plug adapter includes an input component 100 and an output component 500, both of which have housings. The first housing 3 of the input component 100 contains two sets of plugs that extend in different directions. The two sets of plugs are fixed together, forming a single unit. When the first set of plugs 1 is extended to the left, the second set of plugs 2 retracts to the left; conversely, when the second set of plugs 2 is extended to the right, the first set of plugs 1 retracts to the right. Only one set of plugs can be used at a time. The output component 500 has an AC or DC power socket 52 for inserting other types of plugs to provide power. For example, in Figure 1-4, the power socket 52 is an AC power socket, while in Figure 5-6, it is a DC power socket.
[0038] Since socket specifications and installation directions vary from country to country, the present invention makes the following improvements: As shown in Figures 1-6, the two sets of plugs are connected to the push button 4 outside the first housing 3 via 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, so that the conductive pins of the first set of plugs 1 or the second set of plugs 2 extend outside the first housing 3, adapting to the socket specifications of various countries, simplifying use and improving flexibility.
[0039] As shown in Figures 1-6, the first housing 3 has holes 31 at both its left and right ends that mate with conductive pins; the first housing 3 of the input component 100 has a protruding rotating shaft 32 located below the first housing 3, with its axis perpendicular to the sliding direction of the two plugs; the rotating shaft 32 has a through hole 321 inside, which accommodates the conductive connecting rod 33 of the live wire and the neutral wire, and the conductive connecting rod 33 is responsible for transmitting power from the input component 100 to the output component 500; a shaft is provided above the second housing 5 of the output component 500. Hole 51, the size and position of which correspond to the rotating shaft 32, and the input component 100 and the output component 500 achieve relative rotation through the coupling of the rotating shaft 32 and the shaft hole 51, thus forming a rotatable assembly structure. When the first plug 1 or the second plug 2 of the input component 100 is inserted into the wall socket to draw power, the position and orientation of the power socket hole 52 of the output component 500 can be changed by rotating the output component 500, thereby facilitating the insertion of the plug in different directions, improving the convenience and compatibility of use, and is especially suitable for travel and other occasions.
[0040] Referring to Figures 1-6, the pivot 32 of the input component 100 is located 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 pivot 32 of the input component 100; the input component 100 and the output component 500 are coupled through the pivot 32 and the shaft hole 51, aligning the original left and right ends of the first housing 3 and the second housing 5, allowing them to rotate relative to each other; since the center of rotation 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 first housing of the input component 100... The right end will rotate to the left side of the second housing of the output component 500, forming a protruding end; or, since the rotation center is biased towards the right side 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 to the right side of the second housing 5 of the output component 500, forming a protruding end 101; when the conductive pin of the second plug 2 is pushed out from this protruding end and inserted into the European standard socket, the protruding end 101 can extend into the recess of the European standard socket, thereby ensuring that the first housing 3 is compatible with the European standard socket, and thus ensuring the stability after docking. Among them, the European standard socket with model CEE7 / 3 or CEE7 / 5 has a recess (i.e., groove) on the surface of the socket, which is used to adapt and dock with the protruding end 101, thereby achieving a stable connection.
[0041] As shown in Figure 7, the first live wire conductive pin 11 of the first plug group 1 and the second live wire conductive pin 21 of the second plug group 2 constitute a live wire conductive pin module 10, and the first neutral wire conductive pin 12 of the first plug group 1 and the second neutral wire conductive pin 22 of the second plug group 2 constitute a neutral wire conductive pin module 20; the conductive pins of the two plug groups are arranged in opposite directions; it is worth mentioning that the first live wire conductive pin 11 and the first neutral wire conductive pin 12 shown in Figure 7 can be interchanged with each other, and correspondingly, the second live wire conductive pin 21 and the second neutral wire conductive pin 22 can be interchanged with each other.
[0042] The input component 100 has a sliding groove 34 at the center of both sides of the first housing 3. The extension arm 41 of the push button 4 passes through the sliding groove 34 and is connected to the live wire conductive needle module 10 and the center wire conductive needle module 20 respectively. By moving the push button 4 horizontally, the extension arm 41 of the push button 4 can move horizontally in the sliding groove 34, thereby driving the first set of plugs 1 and the second set of plugs 2 to slide left and right, that is, driving the first set of plugs 1 and the second set of plugs 2 to slide to the left or right synchronously.
[0043] As shown in Figures 7-8, both the fire wire conductive pin module 10 and the center wire conductive pin module 20 have a guide groove 301 in their center. The extension arm 41 of the push button 4 has a positioning tooth 411, which can extend into the guide groove 301 and move within it. Correspondingly, the inner edge of the slide groove 34 of the input component 100 has a limiting boss 341 that cooperates with the positioning tooth 411. When the push button 4 is pressed on both sides, the positioning tooth 411 of the extension arm 41 disengages from the limiting boss 341, causing the two sets of plugs to slide. Similarly, when the push button 4 is not pressed on both sides, the positioning tooth 411 of the extension arm 41 engages with the limiting boss 341 to achieve positioning, thereby ensuring that the two sets of plugs are stably positioned inside the first housing 3, preventing the two sets of plugs from moving accidentally, and thus ensuring the quality of the entire plug converter.
[0044] As shown in Figures 7-9, an insulating bracket 30 is provided in the center of the live wire conductive needle module 10 and the center wire conductive needle module 20. The insulating bracket 30 connects the live wire conductive needle module 10 and the center wire conductive needle module 20 into one unit. The insulating bracket 30 is provided with the guide groove 301, which accommodates one or more return springs 302. The positioning teeth 411 on the extension arm 41 are inserted into the guide groove 301 and contact the return springs 302. The elastic force of the return springs 302 pushes the positioning teeth 411 of the extension arm 41 to push against the slide groove 34 of the input component 100, and the positioning teeth 411 are restricted by the limiting boss 341, thereby confining the live wire conductive needle module 10 and the center wire conductive needle module 20 within the first housing 3 to prevent them from being accidentally pushed and moved.
[0045] As shown in Figures 10-11, each of the live wire conductive needle module 10 and the neutral wire conductive needle module 20 has a set of conductive rails 40 below it. Each of the two ends of the conductive rail 40 has a folded edge 401 to maintain contact between the live and neutral wire conductive needle modules and the conductive rail 40. That is, the live wire conductive needle module 10 forms stable contact with one set of conductive rails 40, and the neutral wire conductive needle module 20 forms stable contact with the other set of conductive rails 40. The rotating shaft 32 has two parallel conductive disks 35 at its end, and the conductive disks 35 are fixed to the rotating shaft. The conductive disk 35 is located inside the output component 500. Its rotation direction is perpendicular to the axis of the input component 100 and rotates synchronously with it. The conductive connecting rod 33 connects the conductive rail 40 to the conductive disk 35. A conductive clamping piece 501 is provided inside the output component 500, which contacts the conductive disk 35. When the input component 100 and the output component 500 rotate relative to each other, the conductive clamping piece 501 and the conductive disk 35 remain in contact, i.e., always in a conductive state. There are two conductive clamping pieces 501, one conductive disk 35, one conductive rail 40, and one conductive connecting rod 33, which are sequentially connected to maintain conductivity.
[0046] As shown in Figure 12, the first live wire conductive pin 11 and the first neutral wire conductive pin 12 of the first plug 1 are both flat and have a threaded conductive shaft 102 at their root. The second live wire conductive pin 21 and the second neutral wire conductive pin 22 of the second plug 2 are both circular and have a conductive shaft hole 202 at their root. The conductive shaft hole 202 also has a thread that mates with the conductive shaft 102. The conductive shaft 102 and the conductive shaft hole 202 are coupled to each other and can rotate. By adjusting the relative angle of the first live wire conductive pin 11 and the first neutral wire conductive pin 12 in the first plug 1, the first plug 1 can be adapted to American and Australian sockets, making it more convenient to use.
[0047] In another embodiment, as shown in Figures 13-14, the push button 4 has a hole 42, and a button 43 that can move up and down is installed in the hole 42; a stop block 6 is provided between the fire wire conductive needle module 10 and the center wire conductive needle module 20. The stop block 6 can move up and down, and has a return spring 302 inside, and has inclined surfaces 61 on both sides; the upper end head 62 of the stop block 6 protrudes outside the housing of the input component 100, and can be pressed down by the button 43; both the fire wire conductive needle module 10 and the center wire conductive needle module 20 have protrusions 103 on their sides, and the protrusions 103 cooperate with the inclined surfaces 61 of the stop block 6; when the push button 4 is pushed... When the live wire conductive needle module 10 and the neutral wire conductive needle module 20 move to the left or right, the protrusion 103 slides along the inclined surface 61 of the stop block 6 and pushes the stop block 6 downward. After the protrusion 103 slides past the inclined surface 61, the stop block 6 rises under the action of the return spring 302, restricting the protrusion 103 in a specific position, thereby locking the position of the live wire conductive needle module 10 and the neutral wire conductive needle module 20, and fixing the corresponding conductive needles in the effective contact position. By pressing the button 43, the upper head 62 of the stop block 6 is pressed down by the button 43, and the protrusion 103 is released from the restriction of the stop block 6, thereby releasing the fixed state of the live wire conductive needle module and the neutral wire conductive needle module.
[0048] In another embodiment, the push button 4 has a different structure, specifically:
[0049] Referring to Figure 15, the lower end of the push button 4 is provided with an extension arm 41, which penetrates the upper end of the first housing 3 of the input component 100; the end of the central extension arm 41 is provided with a protrusion 44 with a spring upper groove, which is used to accommodate the return spring 45; a connecting block 104 is provided in the center of the fire wire conductive needle module 10 and the center wire conductive needle module 20, which is used to connect the fire wire conductive needle module 10 and the center wire conductive needle module 20 into one unit, and a spring lower groove 105 is provided in the center of the connecting block 104, in which the protrusion 44 is slidably nested. The lower end of the return spring 45 is connected to the spring. The bottom of the unsprung groove 105 contacts the spring, ensuring that the return spring 45 is confined in the spring groove of the protrusion 44, thereby providing elastic force to the protrusion 44. The upper interior of the first housing 3 of the input component 100 is provided with a slot 36 for limiting the position of the protrusion 44. The protrusion 44 engages with the slot 36, thereby ensuring that the live wire conductive needle module 10 and the center wire conductive needle module 20 are locked in the first housing 3, preventing the live wire conductive needle module 10 and the center wire conductive needle module 20 from moving. When the push button 4 is pressed, the protrusion 44 disengages from the slot 36, and the push button 4 can drive the live wire conductive needle module 10 and the center wire conductive needle module 20 to move in the left and right directions.
[0050] In another embodiment, as shown in Figure 16, the present invention further includes an independent British ground plug 7, which has a ground pin 71, and downwardly extending extension legs 72 on both sides of the British ground plug 71. A metal plate 73 is provided in the middle of the extension legs 72, and a limiting hole 721 is provided at the end of the extension legs 72. A locking protrusion 722 is also provided in the middle of the extension legs 72. A groove 303 matching the size of the locking protrusion 722 is provided on the upper part of the first housing 3 of the input component 100, wherein there are two locking protrusions 722 and two grooves 303. The locking protrusion 722 of the British ground plug 7 is inserted into and stands upright on the first housing 3. When the second set of plugs 2 is pushed out of the first housing 3, the limiting hole 721 allows the conductive pin of the second set of plugs 2 to pass through, thus fixing the British ground plug 7 onto the second set of plugs 2. This assembly is extremely simple and ensures the stability of the assembly structure. It can also meet the needs of different types of sockets (such as UK sockets).
[0051] A magnet 502 can also be installed on the second housing 5. When the British ground plug 7 is inserted into the power socket hole 52 on the second housing 5, the iron piece 73 on the British ground plug 7 is attracted and fixed, ensuring that the British ground plug 7 is stably inserted into the second housing 5, thus achieving the function of storage.
[0052] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention. For example, different countries have defined directions for the position of the live wire and the neutral wire of the plug pin, which may be opposite to this embodiment. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present invention should be included in the scope of the claims of the present invention.

A rotary multi-specification plug adapter according to claim 5, characterized in that: An insulating bracket is provided in the center of the live wire conductive needle module and the neutral wire conductive needle module. The insulating bracket connects the live wire conductive needle module and the neutral wire conductive needle module into one unit and is provided with a guide groove. The guide groove accommodates one or more return springs. The positioning teeth on the extension arm are inserted into the guide groove and contact the return springs. The elastic force of the return springs pushes the positioning teeth of the extension arm to push against the slide groove of the input component and makes the positioning teeth restricted by the limiting boss.
7. A rotary multi-specification plug adapter according to claim 3, characterized in that: Below each of the live wire conductive needle module and the neutral wire conductive needle module is a set of conductive rails. Each of the two ends of the conductive rails has a folded edge to maintain contact between the live wire and neutral wire conductive needle modules and the conductive rails. At the end of the rotating shaft are two parallel conductive disks, which are fixed to the rotating shaft and located inside the output component. The rotation direction of the conductive disks is perpendicular to the axis of the rotating shaft and rotates synchronously with the rotation of the input component. The conductive connecting rod connects the conductive rails to the conductive disks. Inside the output component is a conductive clamping piece that contacts the conductive disks. When the input component and the output component rotate relative to each other, the conductive clamping piece and the conductive disks always remain in contact.
8. A rotary multi-specification plug adapter according to claim 3, characterized in that: The push button has a hole with a movable button inside. A stop block is located between the live wire and neutral wire conductive needle modules. This stop block is movable and contains a return spring, with inclined surfaces on both sides. The upper end of the stop block protrudes from the input component housing and can be pressed down by the button. Both the live wire and neutral wire conductive needle modules have protrusions on their sides that engage with the inclined surfaces of the stop block. When the push button moves the live wire and neutral wire conductive needle modules to the left or right, the protrusions slide along the inclined surfaces of the stop block, pushing it downwards. After the protrusions pass the inclined surfaces, the stop block rises under the action of the return spring, restricting the protrusions to a specific position, thus locking the positions of the live wire and neutral wire conductive needle modules and fixing the corresponding conductive needles in an effective energized position. By pressing the button, the upper end of the stop block is pressed downwards, causing the protrusions to disengage from the stop block, thereby releasing the fixed state of the live wire and neutral wire conductive needle modules.
9. A rotary multi-specification plug adapter according to claim 1, characterized in that: The push button has an extension arm at its lower end, which extends through the upper end of the first housing of the input component. The end of the extension arm has a protrusion with an upper spring groove for accommodating a return spring. A connecting block is located at the center of the fire wire conductive needle module and the center wire conductive needle module, connecting them as a single unit. A lower spring groove is located at the center of the connecting block, and the protrusion is slidably nested within it. A retaining groove is located at the upper interior of the first housing of the input component to limit the position of the protrusion. When the push button is pressed, the protrusion disengages from the retaining groove, and the push button drives the fire wire conductive needle module and the center wire conductive needle module to move in the left-right direction.
10. A rotary multi-specification plug adapter according to claim 1, characterized in that: It also includes an independent British ground plug, which has a ground pin and downward-extending extension legs on both sides. The extension legs have a metal plate in the middle section and a limiting hole at the end. The extension legs also have a locking protrusion in the middle section. The first housing of the input component has a groove on its upper part that matches the size of the locking protrusion. The locking protrusion of the British ground plug is inserted into and stands on the upper part of the first housing. When the second set of plugs is pushed out of the first housing, the limiting hole can be passed through by the conductive pin of the second set of plugs, so that the British ground plug is fixed on the second set of plugs.
