Description

Curtain rotation structure

The invention is a curtain rotating structure, in particular to provide a rotating structure with a more stable curtain rolling and retracting.

Curtains in daily life are often used indoors to block sunlight or external sights. They have privacy and privacy. However, curtains are widely used. In addition to being shielded, they can be used with special curtains. It has the effect of fire and smoke prevention, especially for the use of fireproof building materials such as fire doors, but regardless of the function, the use of the curtain is often seen to be installed under the building structure parallel to the ground such as the ceiling by hanging the device. Outside the curtain on the slide rail for parallel sliding, the other type of curtain mainly curls the curtain in the upper position through the top mounting rolling device, and stretches the curtain from top to bottom to the ground or the bottom of the shelter. The end is used to complete the action of downwardly covering the shadow, or the opposite is scrolled up to the position of the rolling device, and then curled into a bundle and stored above.

Please refer to the embodiment of the conventional curtain rotation structure of FIG. 1 and FIG. 2, but the above-mentioned scrolling downwardly draping curtain is used for a large-area shielding purpose, because the shielding area is relatively large or the curtain is After the material is thicker and other factors, the curtain curtain will form a relatively large diameter curtain and the weight is also quite large. Therefore, a rotating structure with stronger structural strength is needed to support the curled scroll. 1 is a conventional curtain rotation structure 30, which mainly has a frame body 31. One corner of the frame body 31 has an open end, and a wall plate is protruded from the inner surface of the frame body 31.
