Abstract

A hollow glass with a built-in sun-shading curtain and a hollow glass system are disclosed. The hollow glass comprises a curtain body (1) arranged in the hollow glass and a synchronous belt drive system (33, 34) arranged on the sides of the curtain body (1). A pulling rope (11) passes through the curtain body (1). One end of the pulling rope (11) is connected with the bottom of the curtain body (1), and the other end is driven and connected to the synchronous belt (34) of the synchronous belt drive system (33, 34) by a pulling rope turning system (32) at the top of the curtain body (1). Since the synchronous belt drive system (33, 34) is additionally arranged and the pulling rope (11) and the synchronous belt drive system (33, 34) are connected via the pulling rope turning system (32) and synchronously driven, the pulling rope (11) in the curtain body (1) does not need to twist but drives together with the synchronous belt (34). Since the synchronous belt drive system (33, 34) is very reliable, it is not easy to cause fault. The pulling rope (11) does not need to twist and therefore the problem of the fault caused by the snarling of the pulling rope (11) is forbidden. The system has lower fault rate and longer service life.

Description

[Technical Field]

The present invention relates to the field of insulating glass technology, and more particularly to an insulating glass with a sunshade and an insulating glass system using the above hollow glass.

【Background technique】

Insulating glass is widely used in structures such as hollow glass windows, hollow curtain walls, and hollow doors due to its good thermal and acoustic insulation effects. In addition, a sunshade is added to the insulating glass, such as a venetian blind, a pleated blind or an organ curtain in the insulating glass, so that the privacy can be better ensured while being shaded, and the operation is convenient.

However, since the hollow glass is completely sealed, the hollow portion is often subjected to vacuuming, inert gas treatment, etc., and disassembly and assembly is very complicated, so if the sunshade in the insulating glass fails, the repair is very inconvenient. Therefore, insulating glass requires a low failure rate or even a zero failure rate.

The transmission system of the sunshade in the insulating glass is often designed with reference to a common sunshade. Taking louvers as an example, the existing insulating glass usually has a rotating shaft installed on the top of the blind, the louver is provided with a drawstring and a ladder rope, and the louver has a through hole on the blade, and the drawstring is from the through hole between the blades. Through, one end is fixed on the bottommost blade, the other end is fixedly wound on the reel, the rotating shaft end is provided with a rotating wheel and a track, and the driven magnet is arranged on the track. The external active magnet can drive the driven magnet to move on the track and drive the rotating wheel to rotate, thereby driving the rotating shaft to rotate, and the pulling rope on the rotating shaft is rolled up or unfolded, and the venetian blind is pulled or unfolded.

Since the rope is directly wound onto the reel, the winding rope needs to be disassembled to remove the fault, and for the insulating glass, even a small fault such as a coil is difficult to solve. Therefore, there is a need for a more stable, lower failure rate built-in electrically controlled sunshade.
