Description

Technical Field

[0001] This utility model belongs to the field of power cord technology, and in particular relates to a retractable power cord with protection. Background Technology

[0002] Power cords are an important medium for connecting electrical equipment to the power source. Their main function is to safely and stably transmit electrical energy to the equipment and ensure its normal operation. They conduct electricity from the socket or power adapter to the equipment through internal conductive materials (such as copper or aluminum cores), while the outer insulation layer prevents leakage, short circuits, and electric shock risks, ensuring safe use. In addition, high-quality power cords can reduce current loss and electromagnetic interference, adapt to different voltage and power requirements, and are widely used in household appliances, industrial equipment, and other fields. They are an indispensable basic component in power transmission.

[0003] Existing power cords still have some problems during use. For example, most existing power cords are of fixed length, which are prone to tangling, pulling damage, or overheating due to overload. This not only affects the appearance, but also causes the wire to break due to repeated untangling. Furthermore, when the electrical equipment moves a distance beyond the length of the cord, the internal wires may break or the joints may become loose due to external pulling, which may lead to a short circuit risk.

[0004] To address these issues, we provide a retractable power cord with protection. Utility Model Content

[0005] The purpose of this invention is to provide a retractable power cord with protection, which can adjust the length of the power cord and protect it, thus solving the problem that the length of the power cord cannot be adjusted in the prior art.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5This utility model is a retractable power cord with protection, including a housing 1. A first power cord 2 is provided on one side of the housing 1 and is electrically connected to one side of the housing 1. The housing 1 is also electrically connected to the pay-off roller 5 via a connecting wire. This structure is existing technology and will not be described in detail here. A placement shell 3 is fixedly connected to one side of the housing 1. The placement shell 3 can fix the support rod 7, thereby facilitating subsequent limiting work. A rotating rod 4 is rotatably connected inside the housing 1. One end of the rotating rod 4 extends to the outside of the housing 1 and a handle 20 is fixedly connected to one end of the rotating rod 4. One end of the rotating rod 4 is rotatably connected to one side of the inner wall of the housing 1 via a rotating shaft, and the other end extends into the inside of the housing 1. A pay-off roller 5 is fixedly connected to the surface of the rotating rod 4. The pay-off roller 5 can retract and extend a second power cord 6. The second power cord 6 is sleeved on the surface of the pay-off roller 5. Both sides of the inner cavity of the housing 1 are fixedly connected. A support rod 7 is fixedly connected to the outer casing 1. A movable plate 8 is provided inside the outer casing 1. A clamping plate 9 is fixedly connected to one side of the movable plate 8. Slide plates 10 are fixedly connected to the top and bottom sides of the movable plate 8. The slide plates 10 are slidably connected to the surface of the support rod 7. The slide plates 10 can drive the clamping plate 9 to move through the movable plate 8, thereby clamping the second power line 6. Springs 11 are sleeved on both sides of the surface of the support rod 7. An inclined block 12 is fixedly connected to the top of the movable plate 8. A vertical plate 13 is slidably connected to the top of the outer casing 1. A pressing plate 14 is fixedly connected to the top of the vertical plate 13. A pushing block 15 is fixedly connected to the bottom of the vertical plate 13. A through groove 16 is opened on one side of the outer casing 1. A protective sleeve 17 is provided inside the through groove 16. The second power line 6 is slidably connected inside the protective sleeve 17. The protective sleeve 17 can prevent the second power line 6 from rubbing against the inner wall of the through groove 16 when sliding.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a limiting groove 18 is provided on the inner wall of the through groove 16. The top and bottom of the protective sleeve 17 are fixedly connected to limiting blocks 19. The limiting blocks 19 are slidably connected inside the limiting groove 18. The limiting blocks 19 and the limiting groove 18 can limit the protective sleeve. The top of the placement shell 3 is provided with a sliding groove. The vertical plate 13 is slidably connected inside the sliding groove. One side of the clamping plate 9 is fixedly connected with anti-slip texture. The anti-slip texture is used to increase the friction between the clamping plate 9 and the rotating rod 4. There are four springs 11, which are respectively sleeved on both sides of the surface of the support rod 7. Their two ends are fixedly connected to one side of the moving plate 8 and one side of the inner wall of the placement shell 3, respectively. The springs 11 can limit the rotating rod 4 by the clamping plate 9 through their own elasticity. The protective sleeve 17 is made of rubber. The rubber is used to protect the second connecting line. The shape of the inclined block 12 is trapezoidal. The trapezoidal shape is used to facilitate the push block 15 to push the inclined block 12 to move.

[0030] The working principle of this utility model is as follows: When it is necessary to extend the power cord, the user can directly pull the second power cord 6, which will drive the wire release roller 5 and the rotating rod 4 to rotate and release the cable. When the second power cord 6 contacts the inner wall of the protective sleeve 17, it can avoid the second power cord 6 from rubbing against the edge of the outer shell 1, thereby increasing the service life.

[0031] After adjusting the length of the power cord, the user pulls the pressing plate 14 upwards. The pressing plate 14 moves the vertical plate 13 and the pushing block 15 upwards, releasing the limit on the inclined block 12. Then, the spring 11 pushes the moving plate 8 to move through its own elasticity. The moving plate 8 moves the clamping plate 9 to clamp the rotating rod 4, preventing the rotating rod 4 from rotating.

[0032] When winding up the cable, simply press the pressing plate 14 again. The pressing plate 14 will move the vertical plate 13 and the pushing block 15 downwards. When the pushing block 15 contacts the inclined block 12, the pushing block 15 will push the inclined block 12 to move. The inclined block 12 will move the clamping plate 9 through the moving plate 8, thereby contacting the limit on the second power cable 6. Then, the user will drive the rotating rod 4 to rotate through the handle 20. The rotating rod 4 will drive the unwinding roller 5 to rewind the second power cable 6. After winding up, the user will pull the pressing plate 14 again to release the limit on the inclined block 12. The spring 11 will use its own elasticity to make the clamping plate 9 clamp and lock the second power cable 6. This not only allows for free adjustment of the length, but also effectively prevents cable wear.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
