Description

Technical Field

[0001] The utility model relates to the field of glass - built sun - shading insulating glass, and particularly relates to an internal roller blind driving device, an internal roller blind mechanism and an internal roller blind glass product. Background Art

[0002] Due to the internal roller blind, the internal roller blind glass product can not only meet the sun - shading requirements, but also avoid the cleaning of the roller blind. Therefore, such products have been widely used in a large number of buildings. The internal roller blind glass product is generally used in fields such as doors and windows, glass partitions or glass curtain walls.

[0003] The existing internal roller blind glass products generally drive the reel to rotate through a driving mechanism to realize the winding and unwinding of the curtain cloth on the reel, and the overall weight of the curtain cloth is borne by the reel. When used on doors and windows of conventional sizes, such a design will not cause too many problems. However, with the increasingly wide application fields of such glass products, when using the above - mentioned reel structure on some office buildings, commercial buildings and other buildings, the following problems exist:

[0004] (1) In some commercial buildings, there is often a need for extra - wide sun - shading, so the curtain cloth needs to be designed wider. For this reason, the length of the reel needs to be increased, and the weight of the curtain cloth also increases significantly. Therefore, due to the widening of the curtain cloth, the transmission reel structure has a problem of excessive deflection of the reel, resulting in problems such as insufficient running stability, difficult lifting of the curtain cloth, and reduced service life.

[0005] (2) In some commercial buildings, there is often a need for extra - high sun - shading. Similarly, the overall weight of the curtain cloth will increase greatly, resulting in the above - mentioned problem of excessive deflection.

[0006] (3) When the curtain cloth is designed to be extra - wide and extra - high due to requirements, the overall weight of the curtain cloth will increase greatly, resulting in an increase in the rotational friction force at both ends of the reel, thus affecting the smoothness of the curtain cloth lifting and greatly reducing the use experience.

[0007] Therefore, it is urgent to design an internal sun - shading structure that can meet the design requirements of extra - wide and extra - high. Content of the Utility Model
