Description

Technical Field

[0001] This utility model relates to the field of power adapters, and in particular to a wall-mounted power adapter with a winding structure. Background Technology

[0002] A power adapter, also known as an external power supply, is a voltage conversion device for small portable electronic devices and appliances. A wall-mounted power adapter can be plugged into a wall switch. The adapter connects to the power source via connectors. The adapter also has an external cable for connecting to other devices. However, current adapters have the following technical problems: To better connect to external devices, the external cable is usually not short. However, current adapters do not have a suitable cable retraction device. As a result, when the adapter is not in use, the external cable is left to hang freely on the outside of the adapter and cannot be easily retracted. This makes the external cable easily damaged by external pulling or squeezing, and it is also easy to pull the adapter off the wall. This makes it inconvenient to use and has poor practicality. Utility Model Content

[0003] The present invention aims to provide a wall-mounted power adapter with a winding structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wall-mounted power adapter with a winding structure includes an adapter body and a winding device. The adapter body is connected to an external connector and a plug. The winding device includes an upper cover and a lower cover. The lower cover is detachably connected to the adapter body, and the upper cover is detachably connected to the lower cover. The upper cover and the lower cover are each provided with a through hole. The lower cover is rotatably connected to a winding shaft, which has a storage groove and an installation groove. The lower cover is connected to a spiral spring, the free end of which is connected to the winding shaft. The winding shaft is connected to a positioning block, and there are two sets of positioning blocks. The upper cover is rotatably connected to a rotating rod, which has a positioning groove that cooperates with the positioning block. The rotating rod is connected to a hexagonal block. The upper cover is connected to a fixing plate, which is slidably connected to a limit plate. The limit plate has a limit groove that cooperates with the hexagonal block.

[0006] Preferably, the adapter body is threadedly connected to a threaded rod, and the threaded rod is connected to an abutment block.

[0007] Preferably, the lower cover is connected to a magnet, the adapter body is provided with a placement groove, the magnet is slidably connected to the placement groove, and a magnetic plate is connected to the inner side wall of the placement groove.

[0008] Preferably, the fixing plate is provided in two sets, the fixing plate is provided with a sliding groove, the limiting plate is connected with a sliding block, and the sliding block is slidably connected to the sliding groove.

[0009] Preferably, the cross-section of the hexagonal block is a regular hexagon.

[0010] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0011] (1) This technical solution is equipped with a winding device, which can automatically wind up the external wires through a spiral spring, preventing the external wires from falling to the outside of the adapter when idle, and preventing the external wires from being damaged by external pulling or squeezing, thus greatly improving the safety of the adapter. When the external wires are needed, they can be pulled out by simply pulling them. The structure is simple. The rotation of the winding shaft can be restricted by the sliding limit plate, so that the external wires can work at a certain length, ensuring the stability of the adapter. The upper and lower covers are detachable, which facilitates the inspection of the internal structure and the installation of the winding device, thus improving the practicality of the device.

[0012] (2) This technical solution is equipped with a threaded rod and a stop block. After the adapter is plugged into the wall socket, the stop block can be made to abut against the wall, so as to avoid the adapter tilting and loosening due to the lower end of the adapter having a certain space with the wall after being plugged into the socket. This allows the adapter to be plugged into the wall socket stably, further improving the stability of the adapter. The magnet and the magnetic plate make the cord retraction device quick to remove from the adapter body, improving the convenience of use. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 8 The wall-mounted power adapter with a winding structure shown includes an adapter body 1 and a winding device. The internal electronic components and working principle of the adapter body 1 are known prior art and will not be described in detail here. The adapter body 1 is connected to an external cable 8 and a plug 2. The winding device includes an upper cover 6 and a lower cover 5. The lower cover 5 is detachably connected to the adapter body 1, and the upper cover 6 and the lower cover 5 are detachably connected by bolts. The upper cover 6 and the lower cover 5 are respectively provided with through holes 13 on their left and right sides. The through holes 13 on the upper cover 6 are semi-circular. After the upper cover 6 and the lower cover 5 are fastened together, the two through holes 13 are joined to form a round hole, which facilitates the passage of the external cable 8. A winding shaft 12 is rotatably connected to the inside of the lower cover 5. The winding shaft 12 is provided with a storage groove 23 and a mounting groove 14. A spiral spring 11 is connected to the lower cover 5. The spiral spring 11 is located inside the storage groove 23 and is wound onto the lower cover 5. 1. The free end of the spiral spring 11 is connected to the winding shaft 12, that is, the free end of the spiral spring 11 is connected to the side wall of the storage groove 23. A positioning block 17 is connected to the upper side of the winding shaft 12. There are two sets of positioning blocks 17. The upper cover 6 is rotatably connected to the rotating rod 21. The rotating rod 21 is provided with a positioning groove 15. The positioning groove 15 and the positioning block 17 cooperate with each other. The two sets of positioning blocks 17 can be inserted into the positioning groove 15 and abut against the side wall of the positioning groove 15. The rotating rod 21 is connected to a hexagonal block 16. 6 is located outside the upper cover 6. The hexagonal block 16 has a regular hexagonal cross-section. The upper cover 6 is connected to a fixing plate 19. The fixing plate 19 is slidably connected to a limiting plate 18. The fixing plate 19 has two sets. The fixing plate 19 has a sliding groove 20. The limiting plate 18 is connected to a sliding block 22. The sliding block 22 is slidably connected to the sliding groove 20. The limiting plate 18 has a limiting groove 24. The limiting groove 24 cooperates with the hexagonal block 16. The hexagonal block 16 can be inserted into the limiting groove 24.

[0024] The adapter body 1 is threadedly connected to a threaded rod 3, the threaded rod 3 is connected to an abutment block 4, the lower cover 5 is connected to a magnet block 7, the adapter body 1 is provided with a placement groove 9, the magnet block 7 is slidably connected to the placement groove 9, the inner side wall of the placement groove 9 is connected to a magnetic plate 10, and the magnet block 7 is attracted to the magnetic plate 10.

[0025] When using the device Figure 1 and Figure 3 As shown, at this time, the upper cover 6 and the lower cover 5 are fastened together, the positioning plate is inserted into the positioning groove 15, and turning the rotating rod 21 will drive the positioning rod to rotate, thereby driving the winding shaft 12 to rotate. When it is necessary to restrict the rotation of the winding shaft 12, the limiting block is moved so that the hexagonal prism slides into the limiting groove 24, and the side wall of the limiting groove 24 abuts against the side wall of the hexagonal block 16, as shown. Figure 5 At this point, the hexagonal block 16 cannot rotate, which in turn prevents the rotating rod 21 and the winding shaft 12 from rotating.

[0026] When winding up the external cable 8, the external cable 8 passes through the through hole 13 on the left side of the winding device in sequence, then through the mounting groove 14, and then through the through hole 13 on the right side of the winding device. At this time, rotating the winding shaft 12 will wind the external cable 8 onto the winding shaft 12.

[0027] The specific implementation process is as follows:

[0028] When in use, the external cable 8 is wound onto the winding shaft 12, and the magnet is stored in the placement slot 9. To use the device, insert the plug 2 into the wall socket, then turn the threaded rod 3. The threaded rod 3 moves the contact block 4, causing it to contact the wall, thus improving the stability of the adapter body 1. When the external cable 8 is needed, slide the limit plate 18 to move the hexagonal prism out of the limit slot 24, and directly pull the right end of the external cable 8 to pull it out for use. Simultaneously, slide the winding device out of the placement slot 9. As the external cable 8 is pulled out, the winding shaft 12 also rotates. The rotation of the winding shaft 12 pulls the spiral spring 11, causing it to be stretched. When the external cable 8 is pulled out to a suitable length, slide the limit plate 18 to move the hexagonal prism out of the wall socket 24. The prism slides into the limiting groove 24, preventing the winding shaft 12 from continuing to be installed. Consequently, the external cable 8 will not be pulled out or wound into the winding device. At this time, the external cable 8 can be used stably. When the external cable 8 is idle, the sliding limiting plate 18 causes the hexagonal prism to slide out of the limiting groove 24. At this time, the rotating rod 21 no longer limits the winding shaft 12. Under the restoring force of the spiral spring 11, the winding shaft 12 is driven to rotate, thereby automatically completing the winding of the external cable 8. After winding is completed, the magnet 7 can be inserted back into the placement groove 9. The magnet 7 is attracted to the magnetic plate 10, so that the winding device can be stably placed on the adapter body 1. Subsequently, the upper cover 6 and the lower cover 5 can be removed to inspect the structure inside the upper cover 6 and the lower cover 5.

[0029] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
