Description

Technical Field

[0001] This application relates to the field of cable reel technology, and specifically to a cable reel. 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 shortcomings, such as a limited braking mechanism using friction wheels to stop the cable, and the potential for difficulty in quickly stopping the winding process after prolonged use. 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 that can overcome the defects of the prior art.

[0005] (II) Technical Solution

[0006] The embodiments in this specification provide the following technical solutions:

[0007] This specification provides a cable reel, including a cable reel side plate fixed to the external housing of an electrical appliance for winding up cables. A take-up reel is rotatably mounted at one end of the side plate, and a take-up button is slidably mounted at the other end in the radial direction. A coil spring is mounted on the side plate, one end of which is connected to the take-up reel. A slidable axially oriented limit buckle is mounted on the side plate, located below the take-up button. A locking tongue is provided at the bottom of the limit buckle. A locking flange corresponding to the locking tongue is provided on the side end face of the take-up reel. In normal operation, the lock engages with the locking flange, preventing the take-up reel from rotating clockwise. When the take-up button is pressed down radially, the limit buckle slides axially, disengaging the locking tongue from the locking flange. At this time, the coil spring drives the take-up reel to automatically wind up the cable clockwise.

[0008] In some embodiments, the lower end of the retractable button is provided with a first inclined guide surface, and the limiting buckle is provided with a second inclined guide surface corresponding to the first inclined guide surface. By pushing the second inclined guide surface with the first inclined guide surface, the limiting buckle can be driven to slide along the axial direction, thereby unlocking.

[0009] In some embodiments, the side plate of the reel is provided with an axial mounting cavity for sliding the limiting buckle. The limiting buckle is provided with a through groove. A positioning plate is provided in the mounting cavity. The positioning plate passes through the through groove. A first return spring is installed in the through groove and one end of the first return spring abuts against the positioning plate. The first return spring pushes the limiting buckle inward so that the locking tongue and the locking flange remain locked.

[0010] In some embodiments, a third inclined guide surface is provided on one side of the locking tongue, and a fourth inclined guide surface corresponding to the third inclined guide surface is provided on one side of the locking flange. Therefore, in the locked state of the limiting buckle, the take-up wheel can still rotate counterclockwise under the drive of the third and fourth inclined guide surfaces, thereby realizing manual pulling out of the cable.

[0011] In some embodiments, the side plate of the reel has a mounting groove formed around the outer edge of the shaft, the mounting cavity is located in the mounting groove, a second return spring is provided in the mounting groove, the second return spring abuts against the bottom of the take-up button, the second return spring pushes the take-up button up to reset it, a brake wheel is movably mounted in the mounting groove, a friction part is provided on one side of the mounting groove, and an opening is provided on the other side, the inner side of the take-up wheel passes through the opening and is placed in the mounting groove, so that the brake wheel is located between the take-up wheel and the friction part, the take-up button is inclinedly provided with a movable groove, the brake wheel is provided with a guide post, and the guide post is placed in the movable groove.

[0012] In some embodiments, a spring mounting seat is provided on one side of the reel side plate, the spring is wound inside the spring mounting seat, a positioning buckle is provided on the take-up reel, and one end of the spring is inserted and fixed in the positioning buckle.

[0013] In some embodiments, guide blocks are symmetrically provided on the side plate of the reel, the take-up button is movably inserted into the guide blocks, and a connecting shaft is also provided on the side plate of the reel, the take-up reel being rotatably mounted on the connecting shaft.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the beneficial effects that the at least one technical solution adopted in the embodiments of this specification can achieve include at least the following: the limit buckle can lock the take-up reel in the normal state, and pressing down the take-up button can unlock the take-up reel and directly start automatic take-up. Pressing down the take-up button in the radial direction transmits power to the limit buckle through two inclined guide surfaces, causing the locking tongue of the limit buckle to disengage from the take-up reel to unlock and automatically take up the line through the coil spring; at the same time, after releasing the take-up button, the brake wheel can also drive the take-up reel to automatically decelerate and stop take-up, making it stable and reliable in use.

[0032] Combination Figures 1-9As shown, this application provides a cable reel, including a cable reel side plate 1, which is fixed to the external electrical appliance housing. A take-up reel 2 is rotatably mounted at one end of the side plate 1, and a take-up button 3 is slidably mounted at the other end in the radial direction. A coil spring 4 is mounted on the side plate 1, with one end connected to the take-up reel 2. The coil spring 4 is used to pull the take-up reel 2 to rotate and reel the cable of the external electrical appliance into the cable reel. A limiting buckle 5, which can slide in the axial direction, is mounted on the side plate 1 to limit the movement of the cable. The buckle 5 is located below the take-up button 3. The bottom of the limit buckle 5 is provided with a locking tongue 6. The side end face of the take-up reel 2 is provided with a locking flange 7 that can cooperate with the locking tongue 6. In the normal state, the limit buckle 5 locks the locking flange 7 inward through the locking tongue 6, so that the take-up reel 2 cannot rotate clockwise to take up the line. When the take-up button 3 is pressed down in the radial direction, the limit buckle 5 can be driven to slide in the axial direction, so that the locking tongue 6 disengages from the locking flange 7. At this time, the coil spring 4 drives the take-up reel 2 to automatically take up the line clockwise.

[0033] In some embodiments, such as Figures 4-8 As shown, the lower end of the take-up button 3 is provided with a first inclined guide surface 8, and the limiting buckle 5 is provided with a second inclined guide surface 9 corresponding to the first inclined guide surface 8. When the take-up button 3 is pressed down, the first inclined guide surface 8 can push the second inclined guide surface 9, thereby causing the limiting buckle 5 to slide along the axial direction and disengage from the locking flange 7 to unlock. In this embodiment, the reel side plate 1 is provided with a mounting cavity 10 along the axial direction for sliding the limiting buckle 5. The limiting buckle 5 is provided with a through groove 11, and a positioning plate 12 is provided in the mounting cavity 10. The positioning plate 12 passes through the through groove 11, and a first return spring 13 is installed in the through groove 11, with one end of the first return spring 13 abutting against the positioning plate 12. On plate 12, the first return spring 13 can push the inner wall of the through groove 11 to one side, so that the limiting buckle 5 locks the locking flange 7 along the axial direction of the mounting cavity 10. In addition, a third inclined guide surface 14 is provided on one side of the locking tongue 6, and a fourth inclined guide surface 15 corresponding to the third inclined guide surface 14 is provided on one side of the locking flange 7. After the third inclined guide surface 14 and the fourth inclined guide surface 15 are in contact, they can move relative to each other. At this time, the first return spring 13 contracts, and the limiting buckle 5 will be pushed outward. That is, the take-up reel 2 can rotate counterclockwise at any time. When rotating counterclockwise, the cable in the take-up reel 2 can be pulled out for use without being limited by the limiting buckle 5.

[0034] In some embodiments, such as Figures 2-5As shown, a mounting groove 16 is formed around the outer periphery of the shaft on the side end of the reel side plate 1. The mounting cavity 10 is located inside the mounting groove 16. A second return spring 30 is provided inside the mounting groove 16. The second return spring 30 abuts against the bottom of the take-up button 3. When the take-up button 3 is pressed, the second return spring 30 contracts. After being released, the second return spring 30 drives the take-up button 3 to rise and reset. At the same time, the first return spring 13 drives the limit buckle 5 to reset and lock the take-up wheel 2. A brake wheel 17 is movably installed inside the mounting groove 16. A friction part 18 is provided on one side of the mounting groove 16, and an opening 1 is provided on the other side. 9. The inner side of the take-up reel 2 passes through the opening 19 and is placed in the mounting groove 16, so that the brake wheel 17 is located between the take-up reel 2 and the friction part 19. The take-up button 3 is inclinedly provided with a movable groove 20, and the brake wheel 17 is provided with a guide post 21. The guide post 21 is placed in the movable groove 20. When the take-up button 3 is in the locked state, the brake wheel 17 is pushed up to the upper part of the mounting groove 16 by the movable groove 20. At this time, the two sides of the brake wheel 17 are respectively in contact with the inner wall of the take-up reel 2 and the friction part 19, thereby generating a large frictional resistance, causing the take-up reel 2 to decelerate and gradually stop rotating to take up the line.

[0035] In some embodiments, such as Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, a coil spring mounting seat 26 is provided on one side of the cable reel side plate 1, and the coil spring 4 is wound inside the coil spring mounting seat 26. A positioning buckle 27 is provided on the take-up reel 2, and one end of the coil spring 4 is inserted and fixed in the positioning buckle 27, so that the coil spring 4 can pull the take-up reel 2 to rotate. Guide blocks 28 are symmetrically provided on the cable reel side plate 1, and the take-up button 3 is movably inserted into the guide block 28. A connecting shaft 29 is also provided on the cable reel side plate 1, and the take-up reel 2 is rotatably mounted on the connecting shaft 29.
