Two-cavity hollow glass

Abstract

The invention provides two-cavity hollow glass. The two-cavity hollow glass comprises inner-layer glass and outer-layer glass, wherein middle glass is arranged between the inner-layer glass and the outer-layer glass; the space between the inner-layer glass and the outer-layer glass is divided into an inner cavity and an outer cavity, and the inner cavity is sealed; a middle magnetic control piece and a middle guide rail are both arranged in the inner cavity; the middle magnetic control piece can move along the longitudinal direction of the middle guide rail; the middle guide rail is arranged along an edge fame in parallel or the middle guide rail and the edge frame are integrally molded and manufactured. A shutter mechanism provided by the invention is wholly mounted in the outer cavity in a detachable manner so that the shutter mechanism is convenient to maintain and mount. The outer cavity can adopt ventilation and non-ventilation schemes according to air temperature environments, and the two schemes are suitable for hot or cold regions to use, and can obtain corresponding heat-preservation and energy-saving effects. A magnetic matching scheme can guarantee that three magnetic control pieces work reliably. A dustproof and dust-removing design is adopted so that the energy-saving and heat-preservation problems are solved and the disadvantages of an opening type design of the outer cavity are correspondingly reduced.

Description

technical field [0001] The invention relates to a hollow glass, in particular to a double-cavity hollow glass. Background technique [0002] Built-in louver insulating glass is composed of inner glass, outer glass, frame, venetian blind blades, and blade adjustment mechanism composed of blade lifting mechanism and blade turning mechanism. Because it not only has the performance of ordinary insulating glass and venetian blinds, And it has the unique advantages of beautiful, generous, easy to operate, clean, hygienic, and space-saving, so it has developed rapidly at home and abroad. [0003] However, the built-in louver insulating glass in the prior art has the following defects: first, when the double-layer glass single-cavity built-in louver insulating glass is used in summer, due to the heat absorption of the venetian blind blades and the airtight airtightness inside the glass , so that the temperature rise in the insulating glass is relatively large, there is secondary he...

Problems solved by technology

[0003] However, the built-in louver insulating glass in the prior art has the following defects: first, when the double-layer glass single-cavity built-in louver insulating glass is used in summer, due to the heat absorption of the venetian blind blades and the airtight airtightness inside the glass , so that the temperature rise in the insulating glass is relatively large, there is secondary heat transfer to the room, and the effect of heat insulation and energy saving is not good; Firstly, it solves the secondary heat transfer problem of single-cavity products; thirdly, whether it is a single-cavity or double-cavity product, because the louver mechanism is fixed and sealed in the insulating glass, only the glass can be taken out for repair, and there are maintenance problems.
