Abstract

The invention provides a tensioning device, and the device is used for connecting a shutter shaft and an installation seat. The device comprises a clamping platform and a clamping groove, which are in clamping connection. The clamping platform is disposed on the shutter shaft, and the clamping groove is disposed on the installation seat; or, the clamping platform is disposed on the installation seat, and the clamping groove is disposed on the shutter shaft. The clamping platform and the clamping groove are mutually located in axial and radial directions. Moreover, an axial deformation space is formed between the clamping platform and the clamping groove. The shutter shaft and the installation seat form axial fixed connection through the axial deformation space. The device solves problems that a conventional outdoor louver is low in capability of wind resistance, and cannot meet the safety requirements for outdoor installation.

Description

technical field [0001] The invention relates to the field of outdoor blinds, in particular to a device for tensioning or fixing louvers or blades of the outdoor blinds, that is, a tensioning device. Background technique [0002] Compared with indoor shutters, the big difference between outdoor shutters and indoor shutters lies in the different places and environments of application. The indoor shutters only need to be able to cover the windows and adjust the opening angle of the shutters, without considering the influence of outdoor bad weather conditions. Since the outdoor shutters are set outdoors, they must be able to adapt to various possible severe weather conditions, such as typhoon, heavy rain, sand, hail, snow, ice, etc., and also consider the influence of external accidental conditions, such as anti-theft, Therefore, the development of outdoor shutters with higher safety performance and control performance, the same lifespan as the building envelope, and easy maint...
