Unilateral controlled hollow glass built-in window-shades capable of preventing venetian blinds from sliding down

Abstract

The invention discloses unilateral controlled hollow glass built-in window-shades capable of preventing venetian blinds from sliding down. The window-shades comprise a window body, an inner frame body, inner and outer control mechanisms, blind piece overturning performing mechanisms, the venetian blinds, a blind piece overturning pulling rope tensioning mechanism and blind piece overturning pulling ropes. The window body comprises upper and lower transverse frame tubes, left and right longitudinal frame tubes and inner and outer glass; the inner frame body comprises an upper transverse frame strip and left and right longitudinal frame strips; the blind piece overturning pulling rope tensioning mechanism is arranged on a lower right corner inserting block; and one ends of the blind piece overturning pulling ropes are fixed to the inner control mechanism, the middle parts of the blind piece overturning pulling ropes are connected with the blind piece overturning performing mechanisms andthe blind piece overturning pulling rope tensioning mechanism, and the other ends of the blind piece overturning pulling ropes are fixed to the inner control mechanism. The unilateral controlled hollow glass built-in window-shades are characterized by further comprising an opposite absorbing mechanism used for keeping the inner control mechanism at the position which enables the venetian blinds to be under an upward lifting condition, and the opposite absorbing mechanism is arranged between the lower part of the right longitudinal frame tube and the inner control mechanism. When the venetianblinds are under an upward lifting condition, the opposite absorbing mechanism keeps the inner control mechanism at the descending position, and the condition that the venetian blinds abnormally slidedownward due to the fact that the inner control mechanism abnormally moves upward cannot occur.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a single-control hollow glass built-in blind that can prevent the blind from sliding down. Background technique [0002] The 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 lifting venetian blinds. This kind of windows has the following advantages self-evidently: good heat insulation can reflect the energy saving of buildings; excellent sound insulation performance can avoid the noise of the outside world. Anti-condensation and frost to ensure sufficient indoor light and reflect the desired bright effect; through the adjustment of the deflection angle of the blinds, the required indoo...

Problems solved by technology

[0005] Not limited to the above-mentioned hollow glass built-in blinds generally have the following technical problems: First, when the blinds are in the raised state, that is, when the blinds are fully raised or not completely raised, abnormal downturns often occur. Sliding situation, specifically, when the venetian blind is sliding down abnormally, the outer manipulator, that is, the outer control mechanism of the venetian blind lift rope, together with the inner manipulator, that is, the inner control mechanism of the venetian blind lift rope, slides upward, thereby affecting the opening of the venetian blind effect, that is, contrary to the user's purpose

However, this measure will cause an alternative problem of focusing on one thing and losing the other. The so-called focus on this means that it can ensure that the entire outer slider and the surface of the inner glass form a good rolling pair, that is, to ensure that the outer slider slides freely. The so-called loss of the other means that due to The position of the upper and lower rollers of the outer slider is high, so it is easy to make the entire outer slider high at both ends and low in the middle and cause the outer slider to deform or even break; Sixth, because the cross-sectional shape of the outer manipulator guide rail is Chinese characters Concave, and the mouth of the concave is facing left or right (that is, not facing the inner glass), so external dust and foreign matter can easily invade the sliding hook matching groove of the external controller, which will affect the sliding of the external controller. The shape of the guide rail of the outer manipulator whose cross-section is in the aforementioned concave shape is rigid, which affects the visibility to a certain extent, and because the sliding hook of the outer manipulator will shake in the matching groove of the outer manipulator sliding hook, the amount of shaking will be enlarged When the outer manipulator is moved up and down, the straight line or longitudinal axis of the outer manipulator will be poorly maintained, which will affect the lifting of the venetian blind and the flipping of the curtains, and because the guide rail of the outer manipulator only has the function of sliding the outer manipulator, the function Relatively monotonous; Seventh, because the blind lifting traction rope needs to pass through (that is, be placed on) the traction rope redirection pulley of the blind lifting traction rope redirecting pulley set at the upper right corner of the form, so the lifting and lowering of the blinds The outer control mechanism of the traction rope drives the movement of the inner control mechanism of the venetian blind lifting traction rope, and then the inner control mechanism of the venetian blind lifting traction rope drives the movement of the venetian blind lifting traction rope to realize the lifting process of the venetian blind. The force is large, and the force will be concentrated or transferred to the reversing pulley seat of the venetian blind lifting traction rope. Since the reversing pulley seat of the venetian blind lifting traction rope is supported on the upper right corner insert of the upper horizontal frame tube of the form, so The above-mentioned force is finally borne by the upper right corner inserting block support on the upper right corner inserting block for the blind lifting traction rope redirecting pulley seat matched with the blind lifting traction rope redirecting pulley seat, so that the upper right corner inserting The supporting feet are deformed or even broken, so that the lifting and pulling rope of the venetian blind cannot move normally; eighth, because the material of the inner frame (set between the inner and outer glass) that is in contact with the outer glass is usually used in a conventional way to match the window The upper and lower horizontal frame tubes, left vertical frame tubes, and right vertical frame tubes of the body are made of the same aluminum alloy material, so it is easy to conduct high-temperature heat from the outside to the venetian blind cavity in the form of heat transfer (that is, to the inner and outer glass between), resulting in high-temperature heat accumulation in the cavity of the venetian blind, and high-temperature heat accumulation on a set of magnetic blocks of the inner control mechanism of the curtain flipping traction rope between the inner and outer glass and the control mechanism of the inner control mechanism of the venetian blind lifting traction rope The impact of a group of magnetic blocks is very serious or even fatal, specifically showing the demagnetization of the magnetic block, and the demagnetization of the magnetic block will cause the failure of the magnetic block
