Double control warm frame hollow glass window shade

Abstract

The invention discloses a double control warm frame hollow glass window shade. The double control warm frame hollow glass window shade comprises a rectangular window body, an inner frame body, front glass and rear glass, a venetian blind, a curtain sheet overturning adjustment control mechanism, a venetian blind lifting adjustment control mechanism, a venetian blind lifting and curtain sheet overturning transition mechanism, a curtain sheet overturning external control mechanism and a venetian blind lifting external control mechanism, wherein the rectangular window body is composed of left andright longitudinal frame strips and upper and lower horizontal frame strips, the inner frame body is composed of left and right inner frame strips and upper inner frame strips, and the venetian blindis arranged in a venetian blind cavity. The double control warm frame hollow glass window shade is characterized in that left inner frame strip lightproof extension edges are arranged on the rear walls of the left inner frame strips and extends to the direction of the venetian blind cavity, right inner frame strip lightproof extension edges are arranged on the rear walls of the right inner framestrips and extends to the direction of the venetian blind cavity, gaps between the left end of the venetian blind and the right side of the left inner frame strips are covered by the left inner framestrip lightproof extension edges, and gaps between the right end of the venetian blind and the left side of the right inner frame strips are covered by the right inner frame strip lightproof extensionedges. Privacy and safety of users are ensured, lifting effect is lasting and stable, and lifting pulling ropes of the venetian blind are not prone to breaking free.

Description

technical field [0001] The invention belongs to the technical field of hollow glass products, and in particular relates to a double-controlled warm-frame hollow glass shutter. Background technique [0002] The concept of double control mentioned above refers to: the curtain flipping of the venetian blind is controlled by the cooperation of a curtain flip adjustment control mechanism and a curtain flip outer control mechanism, and a venetian blind lifting adjustment control mechanism and a venetian blind The lifting and lowering of the venetian blinds is controlled by the cooperation of the outer control mechanism of the curtain lifting. Normally, the curtain flip adjustment control mechanism is set on the side between the inner glass and the outer glass, such as the left edge, and the curtain flip outer control mechanism is set at the position corresponding to the curtain flip adjustment control mechanism. The side of the glass facing away from the outer glass and the outer...

Problems solved by technology

[0005] The hollow glass built-in blinds in the prior art including the above-mentioned patents (including single control, double control, three-glass two-chamber and two-glass single-chamber structures) have the following disadvantages in actual use: their 1. Since the opposite sides of the left and right vertical frame strips of the form (also called "rectangular form") need to maintain a gap of 2-3mm between the ends of the venetian blinds, otherwise the venetian blinds When turning over, it will scratch the left and right vertical frame strips or even fail to turn over, and it will rub against the walls on the opposite side of the left and right vertical frame strips during the lifting process of the venetian blinds, which will affect the lifting of the venetian blinds or even fail to lift. The interior of the building can be observed from the aforementioned gap, especially when the indoor light is stronger than the outdoor light (such as turning on the lights indoors at night), which is not conducive to protecting privacy (privacy); The two ends of the curtain flipping traction rope are fixedly connected to the aforementioned curtain flip adjustment control mechanism by manual knotting, so when knotting, there will be situations where the knotting point cannot be grasped correctly or even at all. The margin of slack (elongation) after knotting, so that the length of the curtain-turning rope between the two knotting points is more or less longer than the length actually required by the process, although the excess length is relatively very limited It can even be called negligible, but it will still have a substantial impact on the curtain and the turning effect, because when the user operates, the aforementioned margin must be eliminated first, and then the curtain can be turned as required. On the other hand, after a period of use The traction rope will be elongated when the curtain is turned over, which will also affect the turning effect of the curtain

In addition, the venetian blind lifting traction rope (also called "bottom strip traction rope") used to raise and lower the venetian blind also has the same situation as the aforementioned curtain flipping traction rope to a certain extent; The left and right inner frame strips and the top inner frame strips (also called "upper inner frame strips") of the structural system of the inner frame are made of metal materials according to the industry's customary design concept, so the thermal insulation effect is relatively poor and It is not conducive to the magnetic block of the structural system of the blind flip adjustment control mechanism arranged in the left inner frame cavity of the left inner frame and the venetian blind lifting adjustment control mechanism arranged in the right inner frame cavity of the right inner frame The protection of the magnetic blocks of the structural system of the venetian blinds, the magnetic blocks are easily demagnetized by high temperature, and it is difficult to ensure a long-lasting and stable service life; There is looseness in the fixed connection parts, which has an adverse effect on the lifting of the venetian blinds, especially when one end of the venetian blind lifting traction rope breaks free from the bottom bar, then the venetian blinds cannot be lifted
