Problems solved by technology

[0003] However, if the venetian blind is enclosed in a hollow glass window, it is not easy to replace and repair itself. If the venetian blind fails, the hollow glass window needs to be destructively opened to repair the venetian blind, so the venetian blind itself The stability of quality is particularly important
[0004] The existing venetian blinds are in the transmission device, especially where the pulley is applied, and the pull cord is easy to fall into the gap between the pulley and the side wall, causing the pull cord to be entangled, unable to continue to work, and cause failure

Abstract

The invention relates to a driving device used for a hollow louver. The driving device includes a shell and a concave pulley, wherein the shell is arranged on the outer side of the driving device, theconcave pulley includes a pulley body arranged in the middle of the concave pulley and baffles arranged at the two ends of the pulley body, and the concave pulley can be rotatably installed on the inside wall of the shell. According to the driving device, the concave pulley is used, the baffles arranged on the two sides of the pulley body can effectively avoid that a pull rope in transmission come into a gap between the pulley and the side wall in operation, and transmission failure is prevented.

Description

technical field [0001] The invention belongs to the technical field of glass windows, and in particular relates to a transmission device for hollow shutters and hollow shutters. Background technique [0002] The application of venetian blinds has been widely developed, and external shading can have a better shading effect. External venetian blinds are often used in family rooms and offices to adjust the light entering the room. Many more are set in insulating glass windows, enclosed in insulating glass shutters. [0003] However, if the venetian blind is enclosed in a hollow glass window, it is not easy to replace and repair itself. If the venetian blind fails, the hollow glass window needs to be destructively opened to repair the venetian blind, so the venetian blind itself Quality stability is particularly important. [0004] In the existing venetian blinds, where the transmission device, especially the transmission pulley, is used, the pull cord is easily trapped in the...
