Hidden screen window

Abstract

The invention discloses a hidden screen window. The hidden screen window comprises a driving device containing cavity, a first curtain cloth and a second curtain cloth, wherein a first driving device and a second driving device are arranged inside the driving device containing cavity; one end of the first curtain cloth is fixed to the side wall of a first roller, and the other end of the first curtain cloth is wound on the side wall of the first roller through the first driving device or extends outwards from the side wall of the first roller; one end of the second curtain cloth is fixed to the side wall of a second roller; the other end of the second curtain cloth is wound on the side wall of the second roller through the second driving device or extends outwards from the side wall of the second roller; the length of the first roller corresponds to the length of the second roller; and a first balance weight is arranged at the other end of the first curtain cloth, and a second balance weight is arranged at the other end of the second curtain cloth.

Description

technical field [0001] The invention relates to a screen window, in particular to a concealed screen window, in particular to a concealed electric screen window. Background technique [0002] With the innovation and improvement of hidden screen window technology, a hidden screen window structure has appeared on the market. Its main structural features are: the curtain cloth roll and the drive shaft are matched with each other, and the manual or motor (or Push-pull or release of other driving devices), the curtain cloth can be wound on the drive shaft thereupon, or stretched from the side wall of the drive shaft to the desired direction. However, in the process of winding or releasing, since the curtain cloth cannot be in a tight state all the time, resulting in: 1) the curtain cloth cannot be evenly wound on the drive shaft, or evenly stretched from the side wall of the drive shaft to the desired direction; And 2) due to the uneven winding or release, the driving shaft is u...

AI Technical Summary

Problems solved by technology

However, in the process of winding or releasing, since the curtain cloth cannot be in a tight state all the time, resulting in: 1) the curtain cloth cannot be evenly wound on the drive shaft, or evenly stretched from the side wall of the drive shaft to the desired direction; And 2) Due to this uneven winding or release, the force on the drive shaft is uneven, and the load force on the drive shaft and the motor is increased, thereby reducing the service life of the drive shaft and the motor

In addition, users cannot arbitrarily choose or replace curtain fabrics according to actual needs, so that different light transmission effects or ventilation effects cannot be displayed indoors, which greatly reduces the user experience.
