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

Embodiment 1

[0026] Embodiment one: if figure 2 As shown, the section of the vertical axis 9 of the roller is circular, and the axis 9 deviates from the center of the circle. Within this range, a better feel can be obtained while ensuring the limit effect. When the roller rotates to the closest position between the axis 9 and the contact surface, the distance between the operating device 1 and the traction device 5 is the shortest and the magnetic force is strongest, and this position is the resistance position. In this embodiment, it is only necessary to deviate the axis 9 from the center of the circle, and the processing is the simplest and the cost is relatively low.

Embodiment 2

[0027] Embodiment two: if image 3 As shown, the section of the roller along the vertical axis 9 is elliptical. According to the symmetrical characteristics of the ellipse, there are two closest 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 shortest, 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 precision is higher.

Embodiment 3

[0028] Embodiment three: as Figure 4 As shown, the roller is a polyhedral cylinder with a polygonal cross-section perpendicular to the axis 9, and the vertical distance between the axis 9 and the planes of the polyhedron cylinder is the smallest. The distance between the devices 5 is the shortest 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 at the resistance position is a plane, and the friction force is large, which can reduce the possibility of slipping.

Abstract

The invention discloses hollow glass with a built-in sun-shading curtain, comprising two glass media, a sun-shading curtain between the two glass media, a traction mechanism which controls the sun-shading curtain, and a traction device which is fixedly arranged on the traction mechanism; an operation device which is over against the traction device is arranged outside the hollow glass; at least one of the operation device and the traction device comprises a magnetic material, and the operation device and the traction device are connected through magnetic force; at least one of the operation device and the traction device comprises a first support structure; a first rotating shaft is fixedly arranged on the first support structure; rollers with resistance positions are arranged on the first rotating shaft; and the contact position between at least one roller and the hollow glass is closest to the first rotating shaft in a rotation cycle. According to the hollow glass with the built-in sun-shading curtain, because the rollers with the resistance positions are selected, the sun-shading curtain not only receives the friction force of a contact surface but also receives the regulated component force of the magnetic force in a horizontal direction when stopping moving, so that a self-limiting function is realized, the operation difficulty is reduced, and the operation feel 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 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, a 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 hollow glass and fix it on the traction mechanism of the sunshade A magnetic traction device, and then an operating device is set outside the insulating 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 the method of sliding directl...
