Abstract
The utility model relates to an aluminium alloy rolling shutter section. The utility model is characterized in that the section is a flat block with two rolling ends; a rolling hole (1) on one end is larger than a rolling hole on the other end (2); a rolling surface on the small end can be sliced and matched with the larger rolling hole on the other end. The section of the utility model has the advantages of rational design, uneasy falling in the connecting position, portability, material saving, strong ornamental performance, etc. Compared with the section of the exiting rolling shutter, every square meter can save material from 1.5 kilograms to 1.8 kilograms.
Description
The utility model relates to the aluminium alloy extrusions technical field, specifically a kind of aluminium alloys roller shutter sheet section bar.
Aluminium alloy type section rolling curtain sheet is widely used in various building rolling door, and it has light weight, and is corrosion-resistant; Be convenient to install characteristics such as attractive in appearance.But existing aluminium alloys roller shutter chip architecture is an end curls, and the other end is that a filled circles cooperates with hollow crimp end grafting.This kind connects in the use easily threads off, and takes material, and cost is higher.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of difficult dropout is provided, and saves material, the aluminium alloys roller shutter sheet section bar that reduces cost.
The utility model is achieved in that aluminium alloys roller shutter sheet section bar is flat blocks of curling in two ends, the end hole of curling, and greater than the other end hole of curling, and the little end face that curls can cooperate with the big curling hole grafting of the other end.
Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.
Fig. 1 is roller shutter sheet profile structure figure of the prior art
Fig. 2 is a structure chart of the present utility model
As shown in the figure, the utility model is flat blocks of curling in two ends, and the curling hole of an end 1 is greater than the other end 2 holes of curling, and the little end face that curls can be pegged graft with the big curling hole of the other end and cooperated.Curling hole, two ends is made of two sections circular arcs respectively, and the central angle of the large radius arc of a little end 2 is 82 °, and radius R 2 is 12 millimeters; The central angle of small-radius arc is 157 °, radius R 2 ' and be 4 millimeters.The orthodrome central angle of a big end 1 is 90 °, and radius R 1 is 10 millimeters, and roundlet arc central angle is 145 °, radius R 1 ' and be 5 millimeters.At the fluted ornamental tape 3 of the plane of section bar part.
During use, 1 end of a slice section bar pegged graft with 2 ends of another sheet section bar to be cooperated, and snapping gets final product the rolled curtain door so continuously.
Profile design of the present utility model is reasonable, and the junction is difficult for threading off, and has light, material-saving, ornamental The characteristics such as strong are compared with existing shapes for roller shutter, can save material 1.5-1.8 kilogram for every square metre, Thereby have good economic benefit and a social benefit.
