Problems solved by technology

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

Embodiment 1

[0026] Example one: such as image 3 As shown, the cross section of the roller along the vertical axis 9 is elliptical. According to the symmetry of the ellipse, there are two nearest positions between the axis 9 and the contact surface. When the roller rotates to this position, the distance between the operating device 1 and the traction device 5 is the closest, and the magnetic force is the strongest. The position is the resistance position. . Because the roller has two resistance positions in one rolling cycle, the control accuracy is higher.

Embodiment 2

[0027] Embodiment two: such as Figure 4 As shown, the roller is a polyhedral cylinder with a polygonal cross-section of the vertical axis 9. The vertical distance between the axis 9 and the planes of the polyhedral cylinder is the smallest. Therefore, when the planes of the polyhedral cylinder are in contact with the contact surface, the operating device 1 and the traction The distance between the devices 5 is the closest and the magnetic force is the strongest, and the position is the resistance position. The multi-faceted cylinder can have multiple resistance positions, and the control accuracy is further improved; in addition, the contact surface of the roller in the resistance position is flat, with high friction, which can reduce the possibility of slipping.

Embodiment 3

[0028] Example three: such as Figure 5 As shown, the wheel surface of the roller has at least one flat surface, and the flat surfaces are connected by curved outwardly curved surfaces. The vertical distance between the axis 9 and the plane is less than the distance between the axis 9 and the arc. Therefore, when the roller planes are in contact with the contact surface, the distance between the operating device 1 and the traction device 5 is the closest, the magnetic force is the strongest, and the position is the resistance position. The roller can have multiple resistance positions, and the control accuracy is further improved; in addition, the non-resistance position is a curved surface, the rolling process is relatively smooth, and the hand feel is better.

Abstract

The invention discloses hollow glass with a built-in sun-shading curtain. The hollow glass comprises two glass media, the sun-shading curtain between the two glass media and a traction mechanism for controlling the sun-shading curtain, as well as a traction device fixed on the traction mechanism; an operation device is arranged outside the hollow glass and is opposite to the traction device; at least one of the operation device and the traction device contains magnetic material, and the operation device and the traction device are in magnetic connection; and at least one of the operation device and the traction device is provided with a first support structure, a first rotating shaft is fixed on the first support structure, a rolling wheel with a resistance position is mounted on the first rotating shaft, and at least two positions where the rolling wheel which are in contact with the hollow glass are nearest to the first rotating shaft in one rotation cycle of the rolling wheel. As the rolling wheel with the resistance position is selected, when the sun-shading curtain stops the motion, the sun-shading curtain is not only under the action of the friction force of the contact surface, but also is regulated by the component force of magnetic force in the horizontal direction, and the hollow glass further has the automatic position-limiting function, the operation difficulty is reduced and the operation hand feeling is improved.

Description

Technical field [0001] The invention relates to a hollow glass with a built-in sunshade. Background technique [0002] At present, the field of building energy saving is gradually receiving attention. As an important part of building energy saving, insulating glass is favored by consumers because of its good heat insulation and sound insulation effects. At present, a kind of hollow glass with built-in sunshade is popular on the market. 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 insulating glass and fix it on the traction mechanism of the sunshade A magnetic traction device, and then an operating device is provided outside the hollow glass, which is magnetically connected to the traction device, and the traction device can be driven to move by controlling the operating device, thereby realizing the control of the sunshade. The operating device adopts a method of sliding dir...
