Roller and roller shutter component

Abstract

The invention discloses a roller and roller shutter component, and related to the field of external shading roller shutter window structures. The roller and roller shutter component comprises a rollerand a roller shutter, the roller shutter comprises a plurality of shutter sheets which are sequentially connected from top to bottom, each shutter sheet comprises an arc-shaped shutter sheet body, hooks are integrally arranged at the upper ends of the shutter sheet bodies and face to arc-shaped inner sides of the shutter sheet bodies, hook seats and guide wheel mounting seats are integrally arranged at the lower ends of the shutter sheet bodies and positioned on the arc-shaped outer sides of the shutter sheet bodies, the hook seats are positioned below the guide wheel mounting seats, the hookof each shutter sheet is hooked in the hook seat of the adjacent shutter sheet, the upper ends of the shutter sheets positioned at uppermost end are not provided with hooks and connected with the roller through screws, and the hook seats of an outer ring are sequentially arranged on one side of the guide wheel mounting seats of an inner ring after the component is rolled. The shutter sheet can penetrate each other, rolled space is compact, a smaller roller shutter box can be manufactured to adapt to smaller mounting space, structure strength needed by the shutter sheet is ensured, and the rolled space is reduced.

Description

technical field [0001] The invention relates to the structural field of external sunshade roller shutters, in particular to an anti-theft device for roller shutters. Background technique [0002] At present, aluminum alloy rolling shutter doors and windows mainly include rotating devices, curtains, and guide rails on the left and right sides. The upper end of the curtains is connected to the rotating device, and the two sides of the curtains are respectively connected to guide wheels, and the guide wheels on both sides are set on the corresponding guide rails. , the rotating device drives the curtain up and down. Due to the unreasonable structure of the existing curtain sheet, the volume after rolling is large, so the boxes of aluminum alloy rolling shutter doors and windows are relatively large, and it is difficult to adapt to various installation environments, especially when the space outside the wall is small, aluminum alloy rolling shutter doors and windows will be diff...
