Abstract
A novel hollow glass device with a built-in window shutter includes an inner glass layer, an outer glass layer, a window shutter sandwiched between the inner and outer glass layers, and a frame sealing and connecting the inner and outer glass layers. The window shutter is formed by connecting a plurality of blades by a turning cord in series, and the frame is provided with a window shutter lift mechanism and a window shutter turning mechanism. The window shutter turning mechanism employs a rigid component as a transmission structure, which is not liable to deformation and extension phenomena and loosening and is firm, practical and reliable, thereby ensuring long-term normal use of the hollow glass device. The hollow glass device is overall structurally compact and conveniently and quickly operable, and therefore can easily be further spread and used in more broad fields.
