Description

Technical Field

[0001] This utility model belongs to the field of rope winding and unwinding technology, and in particular relates to a rope winding and unwinding device. Background Technology

[0002] Drawstrings are common in everyday life. We often use them to adjust the size of openings in clothing, hats, shoes, and handbags. Taking hats as an example, the traditional method involves tightening the ends of the drawstring and then securing it with a knot. However, this method can easily come undone during movement due to excessive motion or a loose knot. Furthermore, tying the knot usually requires both hands, making it cumbersome and time-consuming. To address these issues, some manufacturers have invented a rotating device for tightening and securing drawstrings. The drawstring is housed inside the device, and its length and tightness can be adjusted through the mechanical force of internal components. However, this device secures the drawstring to the drawstring wheel by winding it around the wheel, which is cumbersome and requires specific materials for the drawstring. Utility Model Content

[0037] Please refer to Figures 1-13 Embodiment 1 of this utility model provides a rope winding and unwinding device, including a rope wheel 7 and a top cover 1 rotatably mounted to the rope wheel 7. One end of the rope wheel 7 is provided with a mating part 10, and the other end is provided with a limiting hole 9. A winding part 8 is provided on the side of the rope wheel 7, and the limiting hole 9 communicates with the winding part 8. The mating part 10 is provided with two mounting protrusions 12, one end of which is fixedly connected to the rope wheel 7, and the other end of which is provided with a locking block 13. A first toothed ring structure 11 is provided on the outer circumference of the mounting protrusions 12 of the rope wheel 7. A ratchet wheel is rotatably mounted on the rope wheel 7 through the mating part 10. One end face of the ratchet wheel is provided with a second toothed ring structure 24 corresponding to the first toothed ring structure 11, and the other end face of the ratchet wheel is provided with three positioning holes 16. Three elastic rods are provided on the side of the ratchet wheel. The component 15 has one end fixedly connected to a ratchet wheel and the other end of the elastic element 15 having a meshing part 14. It also includes a connecting sleeve 3 sleeved on the outside of the rope wheel 7. The inner side of the top end face of the connecting sleeve 3 has a third toothed ring structure 21, and the outer side of the top end face of the connecting sleeve 3 has a retaining ring 19. The top cover 1 includes a cover end wall and a cover side wall. The inner side of the cover side wall has three retaining strips 6 corresponding to the retaining ring 19, and the outer side of the cover side wall has external threads. The inner side of the cover end wall has three positioning blocks 4 and three L-shaped mounting blocks 5. The side of the connecting sleeve 3 has a lead seat 20, and the bottom end of the connecting sleeve 3 has a mounting buckle 18. The bottom of the connecting sleeve 3 is detachably connected to a base 2. The base 2 has a mounting hole 22 corresponding to the mounting buckle 18, and the side of the ratchet wheel has a mounting protrusion 17 corresponding to the mounting block 5.

[0038] In this embodiment, when using the rope, first insert both ends of the rope into the lead seat 20 on both sides of the connecting sleeve 3, and then insert them into the rope winding part of the rope reel 7 from both sides. Figure 13 As shown, tie the two ends of the rope into a knot. Cut off any excess thread with scissors and secure the knot in the limiting hole 9. In this embodiment, the size of the limiting hole 9 can be adjusted by the thickness of the rope, so that the rope wheel 7 can wind ropes of various thicknesses and materials.

[0039] During installation, the rope is first wound around the rope wheel 7. Then, the positioning hole 16 on the ratchet wheel engages with the positioning block 4 inside the top cover 1, and the mounting protrusion 17 on the side of the ratchet wheel engages with the L-shaped mounting block 5 inside the top cover 1, thus installing the top cover 1 and the ratchet wheel together. The connecting sleeve 3 is rotatably connected to the top cover 1 by the retaining strip 6 inside the top cover 1. Then, the rope wheel 7 is inserted into the connecting sleeve 3. The first toothed ring structure 11 on the rope wheel 7 engages with the second toothed ring structure 24 of the ratchet wheel, thus rotatably engaging the rope wheel 7 and the ratchet wheel. Finally, the mounting buckle 18 at the bottom of the connecting sleeve 3 engages with the mounting hole 22 of the base 2 to complete the assembly of this embodiment.

[0040] [A rope winding and unwinding device according to Embodiment 2 of this utility model]

[0041] For the sake of brevity, only the differences from Embodiment 1 described above will be described.

[0042] Please refer to Figure 15 In this embodiment, the base 2 has a through hole 23, the shape of which corresponds to the shape of the limiting hole 9. In this embodiment, the knot in the through hole 23 can be opened conveniently and quickly through the through hole at the bottom of the base 2, so that the rope can be disassembled without installing an opening device.

[0043] This utility model has at least the following advantages:
