Pull rope locking and adjusting mechanism

Abstract

The utility model relates to the technical field of window decoration, and discloses a pull rope locking and adjusting mechanism which comprises a take-up device fixing seat provided with an inserting cylinder, and a ratchet wheel seat arranged on the bottom wall. And ratchet teeth are arranged at the bottom of the take-up device adjusting disc and are matched with the ratchet seat. A pressure spring is connected between the adjusting disc and the inserting cylinder, a rope penetrating hole is formed in the outer wall of the inserting cylinder, and a groove hole is formed in the adjusting disc. The pull rope needs to penetrate in along the guiding of the rope penetrating hole and then smoothly penetrates through the slotted hole to complete knotting. When the length of the pull rope needs to be flexibly adjusted, a user can conveniently rotate the take-up device adjusting disc, and the tightening function of the pull rope is achieved. A ratchet wheel structure is adopted between the take-up device fixing base and the adjusting disc, so that the stability of one-way locking is ensured, and the pull rope is effectively prevented from being loosened accidentally. If the length of the pull rope needs to be reversely adjusted, the user only needs to slightly pull up the take-up device adjusting disc, and reverse adjustment can be easily achieved. And after the proper length is adjusted, the adjusting disc is released, and the pressure spring quickly resets and compresses the adjusting disc, so that the length stability of the pull rope is ensured. The device is novel in structural design, the adjusting process is simple, convenient and efficient, the manual operation cost is remarkably reduced, and the working efficiency is greatly improved.

Technical Field

[0001] The utility model relates to the technical field of window decorations, in particular to a pull cord locking and adjusting mechanism. Background Art

[0002] With the continuous development of modern home decoration, window decoration, as one of the important elements of interior decoration, plays an irreplaceable role in beautifying the indoor environment and adjusting the indoor light. There are many window decoration products on the market, such as curtains, window screens, blinds, etc. Most of these window decoration products are opened and closed and adjusted by pull-cord operation. However, there are some problems with the traditional pull-cord operation method. At present, the pull-cord fixing method of most curtains mainly relies on knotting. However, this method often makes it difficult to accurately adjust multiple pull cords in a curtain to the same height, and requires meticulous manual fine-tuning based on the proficiency of the workers. This method is not only inefficient, but also requires high operating skills of the workers.

[0003] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a pull cord locking and adjusting mechanism. Utility Model Content

The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a technical solution of a rope tightening and adjusting mechanism: it includes a wire take-up device fixing seat 1, an inserting sleeve 11 is provided on the wire take-up device fixing seat 1, a ratchet seat 13 is provided on the bottom wall of the inserting sleeve 11, a wire take-up device adjusting disk 3 is provided in the inserting sleeve 11, a ratchet tooth 31 is provided at the bottom of the wire take-up device adjusting disk 3, the ratchet tooth 31 cooperates with the ratchet seat 13, a compression spring 2 is connected between the wire take-up device adjusting disk 3 and the inserting sleeve 11, a rope threading hole 111 is provided on the outer wall of the inserting sleeve 11, a slot hole 32 is provided on the wire take-up device adjusting disk 3, a boss 12 is provided in the inserting sleeve 11, an assembly port 33 is provided in the wire take-up device adjusting disk 3, the boss 12 is inserted into the assembly port 33, the compression spring 2 is sleeved on the outside of the boss 12, and the two ends of the compression spring 2 are respectively connected with the inserting sleeve 11 and the wire take-up device adjusting disk 3, a screw 4 is provided in the assembly port 33, the screw 4 is connected with the boss 12, and the wire take-up device adjusting disk 3 is slidably connected with the screw 4.

[0018] In this embodiment, when in use, the user can, as needed, insert the drawstring along the guide of the drawstring hole 111, and make it smoothly pass through the slot 32 to complete the knot. When the length of the drawstring needs to be flexibly adjusted, the user can conveniently rotate the take-up adjustment disk 3. During the rotation process, the interaction between the ratchet teeth 31 and the ratchet seat 13 ensures the stability of the one-way locking, effectively preventing the drawstring from accidentally loosening. As the take-up adjustment disk 3 rotates, the drawstring is gradually tightened to the required length. At the same time, the compression spring 2 provides a stable pressure between the take-up adjustment disk 3 and the insert 11, ensuring the compactness and stability of the structure.
