This existing power cord helps reduce water from getting onto the plug, but it still has the following shortcomings in practical use:

[0004] Firstly, the plugs and sockets at both ends of existing power cords are usually of fixed models. When different types of devices or sockets need to be connected, it is often necessary to replace the entire power cord, which is costly.

[0005] Secondly, existing power cords are prone to tangling when they are too long, causing inconvenience during use and making them difficult to store when not in use. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a power cord that allows for rapid replacement.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A power cord capable of quick-change includes a device plug, a socket plug, a cable, and a cable retractor. The cable retractor includes a U-shaped support, a shaft rotatably mounted in the U-shaped support, a stranding wheel fixedly mounted on the shaft, a fixed cover fixedly connected to the front outer wall of the U-shaped support, and a control component disposed on the fixed cover.

[0009] The cable is wound on a stranded reel, and the cable's take-up and take-out ends are fixedly connected to the equipment plug via a first magnetic connector, while the cable's fixed end is fixedly connected to the socket plug via a second magnetic connector.

[0010] As a preferred technical solution of this utility model, the control component includes a control shaft rotatably mounted on one side of the fixed cover, a worm gear fixedly mounted on the control shaft, a worm wheel fixedly mounted on the shaft body, and a rotating cap fixedly connected to the outer wall of one end of the control shaft.

[0011] In a preferred embodiment of this invention, the worm and the worm wheel mesh with each other, and both the worm and the worm wheel are located within a fixed cover.

[0012] As a preferred technical solution of this utility model, the first magnetic connector includes a first connector sleeve fixedly fitted to the cable take-up end, a permanent magnet ring one fixedly connected to the side wall of the first connector sleeve, and a permanent magnet ring two fixedly connected to the side wall of the equipment plug.

[0013] As a preferred technical solution of this utility model, the second magnetic connector includes a second connector sleeve fixedly fitted to the cable fixing end, a permanent magnet ring three fixedly connected to the side wall of the second connector sleeve, and a permanent magnet ring four fixedly connected to the side wall of the socket plug.

[0014] As a preferred technical solution of this utility model, the surface of the first mating sleeve is provided with a uniformly distributed first anti-slip texture, and the magnetic polarities of the opposite faces of the permanent magnet ring one and the permanent magnet ring two are opposite.

[0015] As a preferred technical solution of this utility model, the surface of the second mating sleeve is provided with a uniformly distributed second anti-slip texture, and the magnetic poles of the opposite faces of the permanent magnet ring three and the permanent magnet ring four are opposite.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the design of the first magnetic connector, enables convenient and quick installation and removal of equipment plugs via magnetic fixation, facilitating the rapid replacement of different types of equipment plugs and better adapting to the connection of different equipment interfaces; furthermore, through the design of the second magnetic connector, it enables convenient and quick installation and removal of socket plugs via magnetic fixation, facilitating the rapid replacement of different types of socket plugs and better adapting to the connection of different sockets; and since the equipment plug and socket plug can also be disassembled and replaced separately, it solves the problem of high overall replacement cost when the power cord is damaged.

[0018] 2. This utility model is equipped with a cable retractor. By controlling the twisted wheel to rotate forward and backward through the control component, the cable on the twisted wheel can be flexibly retracted and extended.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 This embodiment discloses a power cord that can be quickly changed, which includes a device plug 1, a socket plug 2, a cable 3 and a cable retractor. The retractor end of the cable 3 is fixedly connected to the device plug 1 through a first magnetic connector, and the fixed end of the cable 3 is fixedly connected to the socket plug 2 through a second magnetic connector.

[0026] In this embodiment, the cable retractor includes a U-shaped support 4, a shaft 5 rotatably mounted in the U-shaped support 4, a stranding wheel 6 fixedly mounted on the shaft 5, a fixed cover 7 fixedly connected to the front outer wall of the U-shaped support 4, and a control component provided on the fixed cover 7.

[0027] Specifically, the control components include a control shaft 8 rotatably mounted on one side of the fixed cover 7, a worm gear 9 fixedly mounted on the control shaft 8, a worm wheel 10 fixedly mounted on the shaft body 5, and a rotating cap 11 fixedly connected to the outer wall of one end of the control shaft 8.

[0028] Furthermore, the worm 9 and the worm wheel 10 mesh with each other, and both the worm 9 and the worm wheel 10 are located inside the fixed cover 7. The cable 3 is wound around the stranded wheel 6. Then, the worm 9 on the control shaft 8 is driven to rotate forward or backward by the rotating cap 11. Subsequently, the worm wheel 10 meshing with the worm 9 will drive the stranded wheel 6 on the shaft 5 to rotate forward or backward. This facilitates the flexible winding and unwinding of the cable 3 on the stranded wheel 6. This allows for flexible control of the release length of the cable 3 according to different connection conditions, thereby solving the problem that the power cord is easy to get tangled when it is too long, causing inconvenience during use. It also allows for flexible storage and organization of the power cord when it is not in use.

[0029] In this embodiment, the first magnetic connector includes a first connector sleeve 12 fixedly fitted to the take-up and release end of the cable 3, a permanent magnet ring 13 fixedly connected to the side wall of the first connector sleeve 12, and a permanent magnet ring 14 fixedly connected to the side wall of the device plug 1.

[0030] Furthermore, the surface of the first mating sleeve 12 is provided with uniformly distributed first anti-slip textures. The magnetic polarities of the opposite faces of the permanent magnet ring 13 and the permanent magnet ring 14 are opposite. By inserting one end of the cable 3 into the device plug 1, during the insertion process, the permanent magnet ring 13 on the first mating sleeve 12 will be firmly attracted to the permanent magnet ring 14. In this way, the device plug 1 can be easily and quickly disassembled and assembled through the magnetic fixed connection method, which facilitates the quick replacement of different models of device plug 1 and can better adapt to the connection of different device interfaces.

[0031] In this embodiment, the second magnetic connector includes a second connector sleeve 15 fixedly fitted to the fixed end of the cable 3, a permanent magnet ring three 16 fixedly connected to the side wall of the second connector sleeve 15, and a permanent magnet ring four 17 fixedly connected to the side wall of the socket plug 2.

[0032] Furthermore, the surface of the second mating sleeve 15 is provided with a uniformly distributed second anti-slip texture. The magnetic polarities of the opposite faces of the permanent magnet ring 3 16 and the permanent magnet ring 4 17 are opposite. By inserting the other end of the cable 3 into the socket plug 2, during the insertion process, the permanent magnet ring 3 16 on the second mating sleeve 15 will be firmly attracted to the permanent magnet ring 4 17. Through the magnetic fixed connection method, the socket plug 2 can be easily and quickly disassembled and assembled, thereby facilitating the quick replacement of different models of socket plug 2 and better adapting to the connection of different sockets.

[0033] In this embodiment, since the device plug 1 and the socket plug 2 can be disassembled and replaced separately, the problem of high overall replacement cost when the power cord is damaged can be solved.

[0034] Working principle: First, by inserting one end of the cable 3 into the device plug 1, during the insertion process, the permanent magnet ring 13 on the first mating sleeve 12 will be firmly attracted to the permanent magnet ring 14. In this way, the device plug 1 can be easily and quickly disassembled and assembled through magnetic fixed connection, which makes it easy to quickly replace different models of device plug 1 and better adapt to the connection of different device interfaces.

[0035] Next, by inserting the other end of the cable 3 into the socket plug 2, during the insertion process, the permanent magnet ring 3 16 on the second mating sleeve 15 will be firmly attracted to the permanent magnet ring 4 17. Through the magnetic fixed connection method, the socket plug 2 can be easily and quickly disassembled and assembled, thus facilitating the quick replacement of different models of socket plug 2 and better adapting to the connection of different sockets.

[0036] Finally, plug the socket plug 2 connected to the fixed end of cable 3 into the designated socket. Then, drive the worm gear 9 on the control shaft 8 to rotate forward through the rotating cap 11. The worm wheel 10, which meshes with the worm gear 9, will drive the stranded wheel 6 on the shaft 5 to rotate forward, which will facilitate the gradual release of cable 3 on the stranded wheel 6. This allows for flexible control of the release length of cable 3 according to different connection conditions. After cable 3 is released, the device plug 1 can be inserted into the corresponding device interface to complete the connection of the entire power cord.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
