Internal control mechanism for window shutter with built-in hollow glass

Abstract

The invention provides an internal control mechanism for a window shutter with built-in hollow glass. The window shutter with the built-in hollow glass comprises a window body, the inner glass and theouter glass; the space between the inner glass and the outer glass serves as a shutter blind cavity; a shutter blind is arranged in the shutter blind cavity; a shutter blind blade overturning and shutter blind lifting mechanism is arranged in an upper transverse frame strip cavity, and an overturning shaft driving mechanism is arranged at the upper end of a right longitudinal frame strip cavity ;and the internal control mechanism comprises an inner sliding block. The internal control mechanism is characterized in that an inner sliding block upper guiding groove is formed in the upper portionof the rear side of the inner sliding block, an inner sliding block lower guiding groove is formed in the lower portion of the rear side of the inner sliding block, and a tensioning spring cavity isformed in the middle of the rear side of the inner sliding block; a tensioning mechanism comprises a pulley seat, a pulley, a tensioning rope and a tensioning spring; the tensioning spring is accommodated in the tensioning spring cavity, the pulley seat is fixed into the right longitudinal frame strip cavity, and the pulley is supported on the pulley seat; one end of the tensioning rope is connected with the overturning shaft driving mechanism, the middle of the tensioning rope is arranged on the pulley in a sleeving mode, and the other end of the tensioning rope is connected with the lower end of the tensioning spring; and the upper end of the tensioning spring is connected with the overturning shaft driving mechanism. The overturning effect of blades of the shutter blind and the liftingeffect of the shutter blind are ensured.

Description

technical field [0001] The invention belongs to the technical field of hollow glass products, and in particular relates to an internal control mechanism for built-in shutters of 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 buildings and meet the ulti...
