Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of window curtains, and more particularly to a control mechanism and a window curtain. BACKGROUND

[0002] Venetian blinds are generally provided with a control mechanism to control the lifting and leaf opening and closing of the blind. The control mechanisms for controlling the window curtain on the market are mainly controlled by pulling beads or pulling ropes. The main function is to control the larger size and heavier window curtain with smaller force through certain speed reduction ratio. It is basically realized by planetary gear. There are certain disadvantages. One, the planetary gear reduction itself does not have a locking function and needs to be designed with a locking mechanism. Two, the control ropes of the control mechanisms on the market cannot be exchanged forward and backward. In addition, the installation methods of the venetian blinds generally have two kinds of punching installation and non-punching installation. Non-punching installation is more and more popular in the market because it does not damage the wall and is easy to install. The non-punching installation mechanism provided on the window curtain track is used to install the window curtain and other products on the window frame, door frame and other positions. The non-punching window curtain products on the market are generally composed of threaded rods and nuts. Although the structure is simple, there are many inconveniences. One, when the non-punching support distance is long, the nut needs to be adjusted for many turns to tighten the threaded rod against the support surface, which is time-consuming. Two, the support force is provided by the threaded structure, and the tightening torque is small, the support force is insufficient, the tightening torque is large, and the hand force is limited, so tools such as wrenches are needed, and it is not convenient to operate in some corner positions. Three, the thread is easily damaged after repeated use.
