Description

Technical Field

[0001] This invention belongs to the field of curtain technology, and more specifically, relates to a drilling-free installation mechanism and a curtain. Background Technology

[0002] There are generally two installation methods for Venetian blinds: drilled installation and no-drill installation. No-drill installation is increasingly popular due to its ease of installation and lack of wall damage. It utilizes a no-drill installation mechanism on the blind track to install blinds and other products onto window frames, door frames, etc. Most no-drill blinds on the market use a threaded structure, consisting of a threaded rod and a nut. While simple in structure, it has several inconveniences: 1. When the no-drill support distance is long, the nut needs to be adjusted many times to tighten the threaded rod to the support surface, which is time-consuming. 2. While the threaded structure provides support, insufficient tightening torque results in inadequate support, while excessive tightening torque requires tools like wrenches due to limited hand strength, and is inconvenient to operate in corners. 3. Repeated use can easily strip and damage the threads. Venetian blinds generally have an operating mechanism to control the raising and lowering of the blinds and the opening and closing of the slats. Currently, most blind control mechanisms on the market use beaded or cord controls. Their main function is to control larger and heavier blinds with relatively small force through a certain reduction ratio. It is basically implemented using planetary gears. However, it has certain drawbacks: 1. Planetary gears do not have a locking mechanism; a separate locking mechanism is required. 2. In most commercially available operating mechanisms, the control ropes cannot be interchanged by threading them back and forth.

[0003] Therefore, it is essential to design a user-friendly and easy-to-install no-drill installation mechanism and curtain. Summary of the Invention
