Description

Automatic falling prevention shutter and method thereof
Technical Field
The invention relates to a blind window, in particular to a blind window capable of preventing automatic falling and a method thereof.
Background
The hollow glass built-in blind is a window belonging to the category of hollow glass products for sunshade, which is configured by installing blinds that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass, which may be referred to as front glass and rear glass) that are installed in a state of facing each other and that close the peripheral edge portions, and has the following advantages: the heat insulation performance is good, thereby embodying the energy saving of the building; excellent sound insulation to prevent the noise from disturbing; the anti-condensation and anti-frost effects ensure sufficient indoor light and show the expected bright effect; the curtain piece of the blind is adjusted by the deflection angle, so that the required indoor lighting requirement is obtained, the privacy is protected, and the blind curtain piece (the habit is called as the curtain piece for short) is prevented from being polluted by dust, so that the excellent cleaning-free effect is embodied; the decorative effect is ideal for buildings so as to improve the grade of the buildings; the high-rise building has strong impact resistance, good safety and long service life, thereby meeting the installation requirement of high-rise buildings and the extremely long-term use maintenance-free requirement; simple, light and labor-saving to adapt to the operation of people of different ages and physical abilities, etc.
The common drive controller of the hollow glass built-in shutter is provided with two inner control mechanisms and two outer control mechanisms, wherein one of the two inner control mechanisms controls the turnover angle (inner turnover and outer turnover, also called front turnover and rear turnover) of a curtain sheet, the other one of the two inner control mechanisms controls the rope winding or rope unwinding of a lifting traction rope of the shutter, the two outer control mechanisms are respectively in magnetic attraction with the two inner control mechanisms through the inner glass, and the outer control mechanisms drive the inner control mechanisms through the operation of an operator on the outer control mechanisms. In order to avoid interference between the two outer actuating devices, it is common to provide two outer actuating devices and two inner actuating devices on each side of the window.
The grant number CN203547479U discloses a double-handle built-in shutter hollow glass, wherein the turning and lifting are respectively controlled by two handles, and the control mode is more accurate and clear in action. The aluminum alloy frame adopts the design of a European standard notch, and all plastic parts of the fixed or movable shutter are preset in the European standard notch. However, when the shutter is used, particularly when the length of the shutter exceeds 70cm, the weight of the shutter made of aluminum alloy is increased, so that the counter weight on the handle is increased, the moving effect of the handle is poor, the handle is heavy in hand feeling and large in inertia, the traction rope is broken and the service life of the shutter is prolonged, the shutter can automatically slide down or the handle can automatically fall down in the using process, the handle cannot be stopped freely, and the inner handle and the outer handle are separated due to excessive stress.
