Venetian blind lifting traction rope retracting and releasing device of insulating glass built-in louver

Abstract

The invention discloses a venetian blind lifting traction rope retracting and releasing device of an insulating glass built-in louver. The insulating glass built-in louver comprises a window body, front glass, rear glass, middle glass, an inner control mechanism, an outer control mechanism, a venetian blind, an overturning shaft drive mechanism and a traction tooth band expanding mechanism. The window body is formed by connecting a left longitudinal frame strip, a right longitudinal frame strip, an upper transverse frame strip and a lower transverse frame strip. The venetian blind lifting traction rope retracting and releasing device comprises a left traction rope winding roller bearing seat, a right traction rope winding roller bearing seat, a left traction rope winding roller, a right traction rope winding roller and an overturning shaft. The left traction rope winding roller bearing seat is arranged at the left end of the upper transverse frame strip, the right traction rope windingroller bearing seat is arranged at the right end of the upper transverse frame strip. The left traction rope winding roller is supported to the left traction rope winding roller bearing seat, and theright traction rope winding roller is supported to the right traction rope winding roller bearing seat. The right end of the overturning shaft extends to the right side of the right traction rope winding roller bearing seat, and is connected with the overturning shaft drive mechanism. The venetian blind is connected with the left and right traction rope winding rollers. The service life of a traction rope is long; and lifting stability is good and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of hollow glass products, and in particular relates to a venetian blind lifting traction rope retractable device for a built-in louver in hollow glass. Background technique [0002] The above-mentioned hollow glass built-in shutters have the following self-evident advantages: good heat insulation to reflect the energy saving of the building; excellent sound insulation to avoid the noise from the outside world; anti-condensation and frost to ensure indoor light Sufficient and reflect the desired bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained and the privacy can be protected, and the venetian blinds can be free from dust. Effect; it is ideal for embellishment of buildings to improve the grade of buildings; strong impact resistance, good safety and long service life to meet the installation requirements of high-rise...
