Double layer hollow glass with built-in window shade

Abstract

The invention discloses a double layer hollow glass with built-in window shade. The double layer hollow glass with the built-in window shade comprises a rectangular window body, an inner frame, an internal control mechanism and an external control mechanism, a venetian blind and a venetian blind curtain sheet overturning and venetian blind lifting mechanism, an overturning shaft driving mechanism,a tensioning rope tensioning and guiding mechanism and a traction teeth belt first and second tensioning rope. The double layer hollow glass with the built-in window shade is characterized in that the venetian blind curtain sheet overturning and venetian blind lifting mechanism comprises an overturning shaft, a pair of rotary shaft head support seats and a pair of pulling rope winding rolls, thepair of the rotary shaft head support seats are arranged in a upper frame cavity, the pair of the pulling rope winding rolls is supported on the pair of the rotary shaft head support seats, the overturning shaft is fixed to the pair of the pulling rope winding rolls, the left and right ends of the overturning shaft stretch out of the pair of the pulling rope winding rolls and the right end of theoverturning shaft is connected with the overturning shaft driving mechanism, the upper ends of a pair of curtain sheet overturning ladder rope is winded on the pair of the pulling rope winding rolls in a sleeving mode, and the upper ends of a pair of venetian blind lifting pulling ropes is winded on the pair of the pulling rope winding rolls. Rectangular window bodies with the length noticeably greater than the height and bottom control requirements that the rectangular window bodies are installed at a high position are met.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a double-layer hollow glass built-in shutter. Background technique [0002] The double-layer hollow glass built-in shutters mentioned above refer to the two pieces of glass (inner glass and outer glass, also called front glass and rear glass) that are arranged in a face-to-face state and seal the surrounding edges. The windows that belong to the category of sunshade hollow glass products are composed of venetian blinds that need to be raised and lowered. This kind of windows has the following advantages self-evidently: good heat insulation to reflect the energy saving of the building; excellent sound insulation performance to avoid external Noise and noise; anti-condensation and frost to ensure sufficient indoor light and reflect the desired bright effect; adjust the deflection angle of the venetian blinds to meet the required indoor lighting re...

AI Technical Summary

Problems solved by technology

It can be seen that the venetian blind lifting traction rope needs to be in contact with the traction slide guide wheel, the venetian blind lifting traction rope change guide wheel, the venetian blind lifting traction rope transition guide wheel, and the turning drum guide wheel, resulting in the following disadvantages: First, due to Every time the venetian blind is lifted and lowered, the lifting rope of the venetian blind will rub against the aforementioned wheels, so it is not enough to really effectively protect the lifting and pulling rope of the venetian blind; Poor and relatively laborious to operate; third, due to the complex structure, it makes processing and assembly troublesome and uneconomical
