Description

technical field

[0001] The invention belongs to the technical field of machinery, and relates to a wind-resistant roller blind, in particular to a steel wire traction mechanism in the wind-resistant roller blind. Background technique

[0002] Roller blinds are widely used in indoor sunshade and shading of various buildings. Most of the existing roller blinds do not have the function of windproof. run.

[0003] For this reason, the applicant previously applied for a curtain wind-resistant component and its curtain (application number: CN2012101517887). The side rails, the upper end of the curtain cloth is fixed on the roll tube, the rails are installed in the side rails, and the curtain wind resistance components are arranged between the rails and the two sides of the curtain cloth, and the curtains The wind-resistant assembly includes a guide column in the installation track and a skirt fixedly connected to the side of the curtain cloth, the outer diameter of the guide col...
