[0054] This utility model provides a pull rope locking assembly, which, compared with the prior art, features easy adjustment and fixing, simple structure, and wide application. It can quickly lock the pull rope in one direction, greatly simplifying operation.
[0055] The present invention also provides an apparatus using a pull cord locking assembly, comprising a pull cord locking assembly as described in any of the preceding claims. In any feasible embodiment, an apparatus using a pull cord locking assembly may be a curtain.
[0056] Example 1
[0057] This embodiment provides a pull-cord locking device, including: a housing 1, a gear 2, a lever 3, a cover plate 4, and a cord cover 5. It mainly works by pushing the lever 3 to drive the gear 2, reducing the gap between the gear 2 and the cover plate 4. This compresses the pull cord located between the two, increasing friction and thus locking the pull cord. Conversely, moving the lever 3 in the opposite direction allows the pull cord to separate from the locking device for unlocking.
[0058] In this embodiment, the outer casing 1 has an internal cavity (achieved by setting a receiving groove) for accommodating the gear structure. A rack 11 is provided at the bottom of the cavity of the outer casing 1, arranged along the direction of the pull rope, on which the gear structure can roll. The front and rear ends of the outer casing 1 are respectively provided with a first opening 12 and a second opening 13 for the pull rope to pass through. Slide grooves 14 are provided on both sides of the outer casing 1, which cooperate with the lever 3, allowing the lever 3 to reciprocate along the slide grooves 14. Mounting bosses 15 are also provided at both ends of the outer casing 1, which cooperate with the cover plate 4 to connect the cover plate 4 to the outer casing 1.
[0059] In this embodiment, the gear structure is located within the cavity of the outer casing 1. One side of the outer circumference of the gear structure engages with the rack 11 inside the outer casing 1, allowing it to roll along the rack. The gear structure has a shaft hole 21 at its center, which engages with and is positioned with a fixed shaft 31 on the lever 3. This allows the gear structure to rotate relative to the lever 3.
[0060] In this embodiment, the lever 3 is U-shaped and is fitted onto the outside of the outer casing 1. A fixed shaft 31 is provided at the U-shaped opening, and the fixed shaft 31 is installed in the sliding grooves 14 on both sides of the outer casing 1, and is connected to the gear structure through the shaft hole 21. This allows the lever 3 to reciprocate along the sliding grooves 14, driving the gear structure to roll along the rack 11.
[0061] In this embodiment, the cover plate 4 is fixedly connected to the outer shell 1 and is located on the opposite side of the gear structure from the rack 11. The pull rope passes between the gear 2 and the cover plate 4. The cover plate 4 and the rack 11 at the bottom of the outer shell 1 form a certain angle, so that the distance between the cover plate 4 and the rack 11 decreases in the locking direction of the pull rope and increases in the unlocking direction of the pull rope. When the lever 3 pushes the gear structure to move along the rack 11 in the locking direction of the pull rope, the gap between the gear 2 and the cover plate 4 becomes smaller and smaller, thereby squeezing the pull rope located between the gear 2 and the cover plate 4, thus locking it. To unlock, simply pull the pull rope in the opposite direction or push the lever 3 to move in the opposite direction. The cover plate is provided with a mounting groove 41, which is installed in conjunction with the mounting boss 15 on the outer shell 1. The cover plate 4 is provided with a limiting buckle 42, which can prevent the outer shell 1 from separating from the cover plate 4 after the outer shell 1 is slid into the mounting groove 41. The cover plate 4 is equipped with a rope-winding post 43, which is mushroom-shaped and is used to allow the excess rope at the other unlocking end to be at least partially wrapped around it after one end of the pull rope is locked. The cover plate 4 has a mounting groove 44 for installation with the rope cover 5. The cover plate 4 has several mounting holes 45 for fixing the pull rope locking device to the required application environment, such as a wall or windowsill. The shape of the cover plate can also be adjusted according to the application environment.
[0062] In this embodiment, the rope cover 5 is a polygonal shell used to house the other release end of the rope after one end is locked, preventing it from being exposed. The rope cover 5 is provided with a second mounting boss 51, which can slide into the mounting groove 44 on the cover plate 4, so that the rope cover 5 and the cover plate 4 are fitted together.
[0063] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present invention.
[0064] The foregoing has provided a detailed description of a pull-cord locking assembly and a device using the pull-cord locking assembly provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
