Technical Field

[0001] The present invention relates to the technical field of power supply conversion equipment, and in particular to a power adapter. Background Art

[0002] A power adapter is a power supply conversion device for electronic devices, usually including a housing, an integrated circuit board installed in the housing, and a plug connected to the integrated circuit board and extending from the housing. The power adapter can convert input AC power into DC power and output it to electronic devices, and is widely used in various scenarios.

[0003] In order to solve the problem that "most existing power adapters cannot flexibly adjust the position of the plug on the shell", the Chinese patent with publication number CN115085561B discloses a power adapter, including: a shell, an integrated circuit board arranged in the shell, and a plug electrically connected to the integrated circuit board; wherein the shell is provided with a mounting groove at the junction of the front side and the upper side thereof, and a rotating seat is provided in the mounting groove; the surface of the rotating seat is slidably connected to a slider, and the sliding direction of the slider is left and right; the plug is rotatably connected to the slider; the rotating shaft of the plug is perpendicular to the sliding direction of the slider, and the rotating shaft of the rotating seat is parallel to the sliding direction of the slider. Although the existing technical problems have been solved, the following problems still exist:

[0004] In this technical solution, although the position of the plug can be changed, the position that can be changed is relatively limited, so corresponding improvements are made to address this problem. Summary of the invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a power adapter.

[0006] A power adapter proposed in the present invention includes a shell, an integrated circuit board installed inside the shell, and a plug installed on the shell. The shell is composed of a front cover and a rear shell that can be detachably installed together. A storage groove is provided at the front end of the front cover, and sliding grooves are provided on both sides of the inner walls of the storage groove. An opening for the wire to pass through is provided in the middle of the storage groove. The plug is located in the storage groove, and sliders are fixed at both ends of the plug. The sliders and the sliding grooves form a sliding fit. When the plug is at the lowest position of the storage groove, this is the common position of the plug. When the space of the socket strip is not enough for the plug of the power adapter to be used in the common position, the power adapter will not be able to be used. At this time, the plug only needs to be pushed upward to a suitable position in the storage groove so that the plug can be normally inserted into the socket of the socket strip for use.

[0007] Preferably, a circular groove is provided on the slide groove, and the slider can rotate at the circular groove. The plug is first moved upward along the storage groove until the slider moves to the circular groove, and then the plug is rotated upward to be parallel to the storage groove, and then the plug is moved downward so that the slider moves to a position below the circular groove, so that the plug is stably stored in the storage groove.

[0008] Preferably, an L-shaped mounting hole is provided on the front of the plug, an L-shaped stop rod is inserted into the mounting hole, and a plurality of stop openings evenly distributed up and down for the stop rod to be inserted are provided on the storage groove, and an elastic connection is formed between the stop rod and the plug. After the plug is moved to a suitable position, when the plug is inserted into the socket, the stop rod is squeezed by the socket and moves along the mounting hole, and finally the end of the stop rod will be inserted into the corresponding stop opening, so that the stop rod can be used to stabilize the plug and the front cover to avoid displacement between the two.

[0009] Preferably, a first spring is fixed to the back side of the stop rod, and the other end of the first spring is fixedly connected to the inner wall of the mounting hole, so that an elastic connection can be formed between the stop rod and the plug through the first spring. When the plug is pulled out of the socket, the first spring can push the stop rod out of the stop mouth, thereby releasing the stable state between the plug and the front cover.

[0010] Preferably, a positioning frame is provided on the back side of the front cover, and a push plate is inserted in the positioning frame, and an elastic connection is formed between the push plate and the positioning frame. The push plate is connected to a driving assembly, and the driving assembly is used to push the push plate outward from the positioning frame. When the plug moves to a position slightly above the storage slot, since the plug is no longer located in the middle of the front cover, when the plug is inserted into a socket on the wall or on the desktop, the end of the front cover away from the plug will be suspended between the wall or the desktop. At this time, if the rear shell is subjected to external force, it is easy to cause the plug to detach from the socket. Therefore, by providing a push plate, when the plug moves upward, the push plate will be pushed outward from the positioning frame by the driving assembly, so that the suspension distance between the front cover and the wall or desktop can be reduced, and the plug will not easily detach from the socket.

[0011] Preferably, the driving assembly includes a push block that can move up and down, the push block is located below the abutment plate, the top of the push block is provided with an inclined surface, the positioning frame is provided with a notch, the abutment plate is located at the notch and abuts against the abutment plate through the inclined surface, connecting plates are fixed on both sides of the push block, a pull rope is fixed on the top of the connecting plate, a pair of notches respectively communicated with the corresponding slide grooves are provided on the front cover, the top of the pull rope passes through the notch and is fixedly connected to the corresponding slider, when the plug moves upward, the connecting plate will be pulled by the pull rope, the connecting plate will synchronously drive the push block to move upward, the push block will push the abutment plate through the inclined surface, thereby pushing the abutment plate outward, and when the stable state between the plug and the front cover is released, the abutment plate will be reset under the action of elastic force.

[0012] Preferably, a guide hole is provided on the support plate, a guide column is inserted into the guide hole, the front end of the guide column is fixedly connected to the positioning frame, a second spring is sleeved on the guide column, and the two ends of the second spring are respectively fixedly connected to the positioning frame and the support plate, so that an elastic connection can be formed between the support plate and the positioning frame by the second spring, and the elastic force of the second spring can be used to push the support plate to return to its original position.

[0013] Preferably, a pair of directional columns are fixed to the bottom of the positioning frame, and the bottom ends of the directional columns pass through the connecting plate, so that the connecting plate can be limited in the up and down directions by the directional columns.

[0014] Preferably, the pull rope is replaced by a pull rod, the bottom end of which is fixedly connected to the connecting plate, and the other end of the pull rod is rotatably connected to the slider via a rotating shaft. When the plug rotates, the pull rod will not be interfered with. When the plug moves, the connecting plate can be pulled by the pull rod.

[0015] Preferably, a pair of ear seats are fixed on the back side of the front cover, and the same shaft rod is rotatably connected between the two ear seats. A pair of cable ties are fixedly sleeved on the shaft rod, and the draw rope is sleeved on the corresponding cable ties. In this way, rolling friction can be formed between the cable ties and the draw rope, thereby reducing the wear on the draw rope and extending the service life of the draw rope.

[0016] Compared with the prior art, the present invention provides a power adapter having the following beneficial effects:

[0017] 1. A power adapter is provided with a movable plug. When the plug is at the bottom of a storage slot, it is the common position of the plug. When the space of the power strip is insufficient for the plug of the power adapter to be used in the common position, the power adapter cannot be used. At this time, the plug only needs to be pushed upward to a suitable position of the storage slot so that the plug can be normally inserted into the socket of the power strip for use.

[0018] 2. A power adapter, by setting a circular groove, first move the plug upward along the storage groove until the slider moves to the circular groove, then rotate the plug upward to be parallel to the storage groove, and then move the plug downward so that the slider moves to the position below the circular groove, so that the plug is stably stored in the storage groove.

[0019] 3. A power adapter, by setting a stop rod, after the plug is moved to a suitable position, when the plug is inserted into the socket, the stop rod is squeezed by the socket and moves along the mounting hole, and finally the end of the stop rod is inserted into the corresponding stop opening, so that the stop rod can stabilize the plug and the front cover to avoid displacement between the two.

[0020] 4. A power adapter, by providing a stopper, when the plug moves to a position slightly above the storage slot, since the plug is no longer located in the middle of the front cover, when the plug is inserted into a socket on a wall or a desktop, the end of the front cover away from the plug will be suspended between the wall or the desktop. At this time, if the rear shell is subjected to external force, it is easy to cause the plug to detach from the socket. Therefore, by providing a stopper, when the plug moves upward, the stopper will be pushed outward from the positioning frame through the driving assembly, thereby reducing the suspension distance between the front cover and the wall or the desktop, so that the plug will not easily detach from the socket.

[0021] 5. A power adapter, by setting a driving component, when the plug moves upward, the connecting plate will be pulled by the pull rope, and the connecting plate will simultaneously drive the push block to move upward, and the push block will push the push plate through the inclined surface, thereby pushing the push plate outward, and when the stable state between the plug and the front cover is released, the push plate will be reset under the action of elastic force.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Reference Figure 1-9 A power adapter comprises a shell, an integrated circuit board installed inside the shell, and a plug 5 installed on the shell. The shell consists of a front cover 1 and a rear shell 2 that can be detachably installed together. A storage groove 3 is provided at the front end of the front cover 1. Slide grooves 4 are provided on the inner walls on both sides of the storage groove 3. An opening 6 for the wire to pass through is provided in the middle position of the storage groove 3. The plug 5 is located in the storage groove 3. Slide blocks 7 are fixed at both ends of the plug 5. The slide blocks 7 form a sliding fit with the slide grooves 4. When the plug 5 is at the lowest position of the storage groove 3, it is the common position of the plug 5. When the space of the socket strip is not enough for the plug 5 of the power adapter to be used in the common position, the power adapter will not be able to be used. At this time, the plug 5 only needs to be pushed upward to the appropriate position of the storage groove 3 so that the plug 5 can be normally inserted into the socket of the socket strip for use.

[0035] Furthermore, a circular groove 8 is provided on the slide groove 4, and the slider 7 can rotate at the circular groove 8. The plug 5 is first moved upward along the storage groove 3 until the slider 7 moves to the circular groove 8, and then the plug 5 is rotated upward to be parallel to the storage groove 3, and then the plug 5 is moved downward again, so that the slider 7 moves to a position below the circular groove 8, so that the plug 5 is stably stored in the storage groove 3.

[0036] Furthermore, an L-shaped mounting hole 9 is provided on the front of the plug 5, and an L-shaped stop rod 10 is inserted into the mounting hole 9. The storage groove 3 is provided with a plurality of stop openings 11 evenly distributed up and down for the stop rod 10 to be inserted into. An elastic connection is formed between the stop rod 10 and the plug 5. After the plug 5 is moved to a suitable position, when the plug 5 is inserted into the socket, the stop rod 10 is squeezed by the socket and moves along the mounting hole 9. Finally, the end of the stop rod 10 will be inserted into the corresponding stop opening 11, so that the stop rod 10 can be used to stabilize the plug 5 and the front cover 1 to avoid displacement between the two.

[0037] Among them, a first spring 12 is fixed to the back side of the stop rod 10, and the other end of the first spring 12 is fixedly connected to the inner wall of the mounting hole 9, so that an elastic connection can be formed between the stop rod 10 and the plug 5 through the first spring 12. When the plug 5 is pulled out of the socket, the first spring 12 can push the stop rod 10 out of the stop mouth 11, thereby releasing the stable state between the plug 5 and the front cover 1.

[0038] Furthermore, a positioning frame 13 is provided on the back of the front cover 1, and a push plate 14 is inserted in the positioning frame 13. An elastic connection is formed between the push plate 14 and the positioning frame 13. The push plate 14 is connected to a driving assembly, and the driving assembly is used to push the push plate 14 outward from the positioning frame 13. When the plug 5 moves to a position slightly above the storage slot 3, since the plug 5 is no longer located in the middle of the front cover 1, when the plug 5 is inserted into a socket on the wall or on the desktop, the end of the front cover 1 away from the plug 5 will be suspended between the wall or the desktop. At this time, if the rear shell 2 is subjected to external force, it is easy to cause the plug 5 to detach from the socket. Therefore, by providing the push plate 14, when the plug 5 moves upward, the push plate 14 will be pushed outward from the positioning frame 13 by the driving assembly, so that the suspension distance between the front cover 1 and the wall or the desktop can be reduced, and the plug 5 will not be easily detached from the socket.

[0039] Among them, the driving assembly includes a push block 20 that can move up and down. The push block 20 is located below the butt plate 14. A slope 27 is provided on the top of the push block 20. A notch 26 is provided on the positioning frame 13. The butt plate 14 is located at the notch 26 and abuts against the butt plate 14 through the slope 27. Connecting plates 18 are fixed on both sides of the push block 20. A pull rope 21 is fixed on the top of the connecting plate 18. A pair of notches 22 that are respectively communicated with the corresponding slide grooves 4 are provided on the front cover 1. The top of the pull rope 21 passes through the notch 22 and is fixedly connected to the corresponding slider 7. When the plug 5 moves upward, the connecting plate 18 will be pulled by the pull rope 21, and the connecting plate 18 will synchronously drive the push block 20 to move upward. The push block 20 will push the butt plate 14 through the slope 27, thereby pushing the butt plate 14 outward. When the stable state between the plug 5 and the front cover 1 is released, the butt plate 14 will be reset under the action of elastic force.

[0040] Among them, the support plate 14 is provided with a guide hole 17, and a guide column 15 is inserted into the guide hole 17. The front end of the guide column 15 is fixedly connected to the positioning frame 13, and a second spring 16 is sleeved on the guide column 15. The two ends of the second spring 16 are respectively fixedly connected to the positioning frame 13 and the support plate 14. In this way, the second spring 16 can form an elastic connection between the support plate 14 and the positioning frame 13, and the elastic force of the second spring 16 can push the support plate 14 to return to its original position.

[0041] A pair of directional columns 19 are fixed to the bottom of the positioning frame 13 , and the bottom ends of the directional columns 19 pass through the connecting plate 18 , so that the connecting plate 18 can be limited in the up and down directions by the directional columns 19 .

[0042] In another embodiment, the pull rope 21 is replaced by a pull rod 28, the bottom end of the pull rod 28 is fixedly connected to the connecting plate 18, and the other end of the pull rod 28 is rotatably connected to the slider 7 via a rotating shaft. When the plug 5 rotates, it will not interfere with the pull rod 28. When the plug 5 moves, the connecting plate 18 can be pulled by the pull rod 28.

[0043] Furthermore, a pair of ear seats 23 are fixed on the back side of the front cover 1, and the same shaft rod 24 is rotatably connected between the two ear seats 23. A pair of cable pulleys 25 are fixedly sleeved on the shaft rod 24, and the pull rope 21 is sleeved on the corresponding cable pulleys 25. In this way, rolling friction can be formed between the cable pulleys 25 and the pull rope 21, thereby reducing the wear on the pull rope 21 and extending the service life of the pull rope 21.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
