Description

Technical Field

[0001] This application relates to the field of cable reel technology, and more specifically to a cable reel with a braking mechanism. Background Technology

[0002] A cable reel, also known as a cord winder or reel, is a device that winds long cables around itself. The cable can be pulled out as needed and wound up again when not in use. Various household appliances require conductive cables to connect to sockets. Ordinary household appliances use fixed-length cables, which may be too short in some situations. A cable reel allows for the use of much longer cables, greatly expanding the range of applications for various appliances. However, existing cable reels have some drawbacks, such as pulling out or retracting the cable too quickly, which can affect the lifespan of the wires. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The problem to be solved by this application is to provide a cable reel with a braking mechanism to overcome the deficiencies in the prior art.

[0005] (II) Technical Solution

[0007] This specification provides a cable reel with a braking mechanism, including a cable reel side plate fixed to an external electrical housing. A take-up reel is rotatably mounted on one end of the cable reel, and a braking mechanism is provided on the take-up reel. The braking mechanism includes a mounting groove on one side of the take-up reel and a brake pad disposed in the mounting groove. One end of the brake pad is hinged in the mounting groove. The cable reel side plate has an inner wall for blocking the brake pad. When the take-up reel rotates clockwise to take up the cable, the brake pad is subjected to centrifugal force, flips outward along the outer side, disengages from the mounting groove, and abuts against the inner wall, forming resistance and reducing the rotational speed of the take-up reel.

[0008] In some embodiments, the take-up reel is provided with baffles at both ends of the mounting groove, the brake pad is located between the baffles and the mounting groove, one end of the mounting groove is provided with a positioning post, and the brake pad is hinged to the positioning post.

[0026] Combination Figures 1-5 As shown, this application provides a cable reel with a braking mechanism, including a cable reel side plate 1, which is fixed to the external electrical housing. A take-up reel 2 is rotatably mounted on one end of the cable reel side plate 1. A coil spring mounting seat 18 is provided on one side of the cable reel side plate 1, and a coil spring 19 connected to the take-up reel 2 is provided in the coil spring mounting seat 18. The coil spring 19 is used to pull the take-up reel 2 to rotate for cable winding. The take-up reel 2 is provided with a braking mechanism, which includes a mounting groove 3 on one side of the take-up reel 2 and a brake pad 4 disposed in the mounting groove 3. One end of the brake pad 4 is hinged in the mounting groove 3. The cable reel side plate 1 is provided with an inner wall 5 for blocking the brake pad 4. When the take-up reel 2 rotates clockwise to wind up the cable, the brake pad 4 is subjected to centrifugal force and flips outward along the outer side, disengaging from the mounting groove 3 and abutting against the inner wall 5 to form resistance, thereby reducing the rotational speed of the take-up reel 2 and thus playing a protective role.

[0027] In some embodiments, such as Figures 3-5 As shown, the take-up reel 2 has baffles 6 at both ends of the mounting groove 3. The brake pad 4 is located between the baffles 6 and the mounting groove 3. The baffles are arc-shaped pieces extending from the surface of the take-up reel 2 to both ends of the mounting groove 3, which serve as a limit to prevent the brake pad 4 from axially disengaging from the mounting groove 3 due to vibration. One end of the mounting groove 3 has a positioning post 7, and the brake pad 4 is hinged to the positioning post 7. The hinge at the end point allows the brake pad 4 to be subjected to centrifugal force and flip outward to disengage from the mounting groove 3 when the take-up reel 2 rotates, thus contacting the inner wall 5. The brake pad 4 also has a limiting groove 8, and the mounting groove 3 has a limiting post 9. The limiting post 9 is placed in the limiting groove 8. The cooperation between the limiting post 9 and the limiting groove 8 allows the brake pad 4 to only shift outward by a certain angle, avoiding a large collision with the inner wall 5 and causing damage to the parts.

[0028] In some embodiments, such as Figure 1 and Figure 2As shown, the side plate 1 of the cable reel has a mounting cavity 10, in which a brake wheel 11 is movably mounted. One side of the mounting cavity 10 has an opening 12, through which the inner side of the take-up reel 2 passes and is placed within the mounting cavity 10. One side of the mounting cavity 10 has a friction part 13, with the brake wheel 11 located between the opening 12 and the friction part 13. A take-up button 14 is slidably mounted on the side plate 1, with an inclined movable groove 15 on the take-up button 14. A guide post 16 is provided on the brake wheel 11, and the guide post 16 is placed within the movable groove 15. A return spring 17 is also provided within the mounting cavity 10, abutting against the lower end of the take-up button 14, and resetting under normal conditions. Spring 17 pushes up the take-up button 14. Movable groove 15 drives brake wheel 11 to rise as a whole through guide post 16, so that its two sides are engaged with the inner wall of take-up wheel 2 and friction part 13. At this time, brake wheel 11 stops take-up wheel 2 from moving. After pressing down take-up button 14, brake wheel 11 descends and disengages from take-up wheel 2 and friction part 13. At this time, take-up wheel 2 rotates to take up the line. After releasing take-up button 14, take-up wheel 2 continues to rise and reset. After contacting the inner wall of take-up wheel 2 and friction part 13, it drives take-up wheel 2 to gradually decelerate and rotate until it stops, completing the braking action. In this embodiment, the side plate 1 of the reel is also provided with connecting shaft 20, and take-up wheel 2 is rotatably mounted on connecting shaft 20.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
