[0003] Traditional power adapters often only focus on their power conversion function in design, and ignore the storage problem of the adapter power cord. Usually, the power cord of the adapter is long and in a natural stretched state. In the actual use environment, this design has many inconveniences. When the power adapter is not used, the power cord is randomly placed, not only occupies a large space, but also easily entangles with other items. The entanglement of the power cord brings great trouble to the user, and it takes time to untangle the entangled wire before each use. This process is not only tedious, but also may cause damage to the power cord if not handled properly during the untangling process, affecting the normal service life of the power adapter.

[0004] In addition, in the case of travel, business trip or limited office environment space, the messy power cord will make the desktop or storage space more messy, affecting the overall neatness and aesthetics. At the same time, the entangled power cord may cause the metal wire inside the core to break or be damaged, which poses a certain safety hazard, such as short circuit, which may cause damage to electronic devices and even users.

[0005] Therefore, in order to solve the problem of inconvenient storage and easy entanglement of the power cord of the traditional power adapter, it is necessary to improve the power adapter and design a power adapter with a take-up function, which can wind up the power cord part when not in use, facilitating storage and avoiding entanglement, improving user experience and use safety.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-8 The utility model provides a technical solution: a power adapter with an anti-fall mechanism, comprising a power supply body 1 and a power supply wire 2, the power supply wire 2 being connected to the power supply body 1 for conductive transmission, a winding drum 3 being provided on the power supply wire 2, the winding drum 3 being used to wind the power supply wire 2 to realize the winding function, a first limiting member 4 and a second limiting member 5 being respectively provided at both ends of the power supply wire 2 for limiting, the first limiting member 4 being provided with a movable positioning member 402 toward one end of the power supply wire 2 for positioning.

[0029] The power adapter with a detachable structure of the present application is mainly composed of a power supply body 1, a power supply line 2, a winding drum 3, a first limiter 4, a positioning member 402 and a second limiter 5, and its detailed working principle is as follows.

[0030] 1. Assembly process

[0031] First, connect one end of the power cord 2 to the power body 1, ensuring that the connection is firm and can conduct electricity normally.

[0032] Next, place the take-up drum 3 in a suitable position and wind the power cord 2 around it. Install a first stopper 4 and a second stopper 5 at both ends of the take-up drum 3, where the bottom of the second stopper 5 is connected to a stable base 6 via a support frame 7.

[0033] The four corners of the stable base 6 are provided with preset openings 601 so as to be reinforced with bolts when necessary. A stable base pad 602 made of rubber material is glued to the bottom of the stable base 6 to increase the friction with the placement surface.

[0034] The second stopper 5 is connected to the end facing the winding drum 3 with a threaded connection tube 501, which is threadedly connected to one end of the winding drum 3. Since the second stopper 5 and the threaded connection tube 501 are an integrated structure, the winding drum 3 can be adjusted by fixing the second stopper 5 and rotating the entire structure to adjust the winding angle.

[0035] A built-in movable groove 401 is opened inside the first limiting member 4, and the positioning member 402 is placed in the built-in movable groove 401. The positioning member 402 and the built-in movable groove 401 are connected by an extrusion spring 403. One end of the extrusion spring 403 is welded to the inner wall of the built-in movable groove 401, and the other end is welded to the positioning member 402.

[0036] A rotating protrusion 405 is provided at the outer end of the first stopper 4, and an outer anti-slip layer 406 is evenly adhered to the outer circumference of the rotating protrusion 405 to facilitate rotation of the first stopper 4. A first protective layer 404 is provided at the end of the first stopper 4 that contacts the power supply line 2, and a second protective layer 502 is provided at the end of the second stopper 5 that contacts the power supply line 2. The first protective layer 404 and the second protective layer 502 are made of rubber to protect the contact surfaces.

[0037] 2. Rewinding Operation

[0038] To rewind the cable, hold the rotating boss 405 and rotate the first stopper 4, loosening the connection between the first stopper 4 and the take-up drum 3 (if previously threaded). The power supply cable 2 is then wound around the take-up drum 3. During the winding process, the positioning member 402, under the action of the compression spring 403, positions the power supply cable 2, preventing it from loosening during the winding process. When the cable is wound to the desired length, the first stopper 4 is rotated again, securing it to the take-up drum 3 via threads or other connection methods, thus securing the power supply cable 2 to the take-up drum 3.

[0039] 3. Operation when using the power adapter

[0040] When the power adapter needs to be used, the reverse operation of the winding process is performed. That is, the first limiting member 4 is rotated to loosen the connection with the winding drum member 3, and then the power adapter wire body 2 is unwound from the winding drum member 3, so that the power adapter wire body 2 is stretched to a suitable length, and the electronic device is connected for power supply operation.

[0041] IV. Working principle

[0042] Winding principle

[0043] The winding drum member 3 is the core component of the winding, and the first limiting member 4 and the second limiting member 5 at both ends are used to limit the position of the power adapter wire body 2. When the winding drum member 3 is rotated, the power adapter wire body 2 will be wound on the winding drum member 3. During the winding process, the positioning member 402 inside the first limiting member 4 will exert a certain pressure on the power adapter wire body 2 under the elastic force of the compression spring 403, so that the wire body is arranged neatly on the winding drum member 3, preventing the wire body from loosening or winding disorderly. The second limiting member 5 is connected with the winding drum member 3 through the threaded connection barrel 501, and by fixing the second limiting member 5 and rotating the winding drum member 3, the winding angle and the tightness can be conveniently adjusted.

[0044] The role of the stable base 6

[0045] The stable base 6 provides support for the entire winding device. The stable bottom pad 602 at the bottom is made of rubber material, which can increase the friction with the placement plane to prevent the entire device from sliding during winding or use. The pre-set hole 601 can be used to fix the device on the desktop or other plane with a bolt when needed, further improving the stability.

[0046] Protection principle

[0047] The first limiting member 4 is provided with a first protective layer 404 at the contact end of the power adapter wire body 2, and the second limiting member 5 is provided with a second protective layer 502 at the contact end of the power adapter wire body 2, both of which are made of rubber material. During the winding process, when the power adapter wire body 2 contacts the first limiting member 4 or the second limiting member 5, the protective layer made of rubber material can prevent the wire body from being scratched or worn, protect the integrity of the power adapter wire body 2, and prolong its service life.

[0048] The above is the working process of the entire device, and the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0049] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
