Louver curtain anti-slip device for hollow glass built-in louver

Abstract

The invention relates to a louver curtain anti-slip device for a hollow glass built-in louver, and belongs to the technical field of sunshade hollow glass products. The hollow glass built-in louver comprises a louver body and a louver curtain lifting traction rope inner control mechanism up and down movably arranged in the louver body; the louver curtain anti-slip device comprises a louver curtainlifting traction rope inner sliding block connection mechanism and a magnetic attraction mechanism, the louver curtain lifting traction rope inner sliding block connection mechanism in a use state isconnected with the louver curtain lifting traction rope inner control mechanism, the portion, corresponding to the lower portion of the louver curtain lifting traction rope inner sliding block connection mechanism, of the magnetic attraction mechanism is fixed with the louver body, and magnetic attraction or release of magnetic attraction of the louver curtain lifting traction rope inner slidingblock connection mechanism and the magnetic attraction mechanism is achieved. The situation that the louver curtain lifting traction rope inner control mechanism slides upwards, so that a louver curtain in a rising state slips abnormally can be avoided, and the demand of a user for the desired opening effect on the louver curtain is met.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a slid-down preventing device for a venetian blind used for built-in louvers of hollow glass. 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 in...

AI Technical Summary

Problems solved by technology

[0005] Theoretically speaking, when the venetian blind is in the state of rising upwards, if the curtain flipping traction rope of the single-control structural system and the internal and external control mechanisms of the venetian blind lifting traction rope do not slide upward, and the double-control structure The internal and external control mechanisms of the venetian blind lifting traction rope in the system do not slide upwards, so the venetian blinds in the rising state, that is, in the open state, will not slide down abnormally, but in the actual use process, when encountering the area When the relatively large hollow glass has built-in louvers, the expansion area of ​​the inner and outer glass and the venetian blind is relatively large and the venetian blind is heavy, so when the venetian blind rises upwards to the top of the venetian blind cavity of the double-layer hollow louver , the inner and outer control mechanisms slide upwards because it is difficult or even impossible to resist the gravity of the venetian blinds. At the same time, the venetian blinds slide down, which affects the opening effect of the venetian blinds.
