Hollow glass with sun-shading curtain inside

Abstract

The invention discloses hollow glass with a sun-shading curtain inside. The hollow glass comprises glass media on two faces, the sun-shading curtain arranged between the glass media on the two faces, a traction mechanism for controlling the sun-shading curtain, and a traction device fixed on the traction mechanism, wherein an operating device is arranged at a position, opposite to the traction device, outside the hollow glass; at least one of the operating device and the traction device comprises a magnetic material, so the operating device is connected with the traction device through a magnetic force; and at least one of the operating device and the traction device comprises a roller of which the roller surface is embedded with a flexible material. In the hollow glass, as the roller with a limiting structure is selected, the sun-shading curtain can be limited automatically based on a theory that the magnetic force is large in a near place and small in a far place under the condition of proper magnetic field intensity; therefore, the operating difficulty is reduced and the operating feel is improved.

Description

technical field [0001] The invention relates to a hollow glass with a sunshade inside. Background technique [0002] At present, the field of building energy saving is gradually being paid attention to. As an important part of building energy saving, insulating glass is loved by consumers because of its good heat insulation and sound insulation effects. At present, there is a popular hollow glass with sunshade installed inside. The sunshade can be controlled by magnetic traction to adjust the light intensity in the room. The specific method is: install the sunshade inside the hollow glass and install it on the traction mechanism Fix a magnetic traction device, and then set an operating device outside the insulating glass, which is magnetically connected with the traction device. By controlling the operation device, the traction device can be driven to move, thereby realizing the control of the sunshade. The operating device adopts the method of sliding directly on the surfa...

AI Technical Summary

Problems solved by technology

The operating device adopts the method of sliding directly on the surface of the glass medium. Due to the large friction force of the sliding method, the operation force is relatively large, and the control accuracy is not easy to grasp, so the operation is very inconvenient

There is an operating device using ordinary rollers on the market, which can roll directly on the contact surface and is easy to operate, but when the power on the operating device along the direction of the contact surface is cancelled, if the gravity of the operating device has a component force along the horizontal direction of the contact surface, Then the friction between the roller and the contact surface alone is not enough to stop the operating device, and an additional limit mechanism needs to be added; even if the operating device is placed horizontally, slight touch and vibration can easily cause it to slide, and the limit effect is not ideal.
