Hollow glass built-in sun-shading apparatus

摘要

The present invention relates to a built-in sun-shading device of hollow glass. The built-in sun-shading device comprises a cord-winding mechanism, a transmission mechanism controlling the rotation of the cord-winding mechanism and a sun-shading mechanism connected onto the cord-winding mechanism. The cord-winding mechanism comprises a cord-winding shaft, a group of cord-winding propellers are arranged on the cord-winding shaft, the transmission mechanism is connected with the cord-winding mechanism, and the sun-shading mechanism is connected onto the cord-winding propellers. The built-in sun-shading device of the hollow glass, which uses a single cord-winding shaft, can wind a plurality of cords and enable the sun-shading mechanism to be folded and unfolded in a balanced mode. The single cord-winding shaft does not need to move back and forth, is simple in terms of structure and has high assembling efficiency. In addition, the built-in sun-shading device of the hollow glass uses the cords to limit slats from moving to and fro, which thus enables the slats to stack up orderly, reduces contact between the slats and hollow glass, protects the coating film on the surface of the hollow glass and reduces friction. Furthermore, the built-in sun-shading device of the hollow glass uses a handle with frictional damping in one direction and overcomes a phenomenon that the large sun-shading mechanism may easily decline itself due to the large self-weight after being lifted.
