Abstract
The utility model relates to a section of a bottom beam for an aluminum alloy curtain rolling door. The utility model is characterized in that the utility model is composed of a bottom surface (1), a support surface (2), a hollow circle (3), and a transition inclined surface (4), wherein, the bottom surface (1) is a plane surface, one side of the support surface (2) stands on the plane surface, the other side of the support surface (2) is connected with the hollow circle (3) through the transition inclined surface (4), and one end of the hollow circle (3) can be inserted and matched with rolling holes of the section for an aluminum alloy curtain rolling sheet. The utility model can be used for the fixation of various aluminum alloy curtain rolling doors. The utility model has the characteristics of reasonable design, simple structure, material saving, flexible operation, good intensity, long service life, beautiful appearance, and firm connection.
Description
The utility model relates to the aluminium alloy extrusions field, specifically is a kind of aluminium alloys rolling door bottom girder section bar.
At present, aluminium alloy extrusions is widely used in various building rolling door, compares it with other material and has light weight, and is corrosion-resistant, is convenient to install, advantage such as beautiful attractive in appearance.But existing aluminium alloys rolling door bottom girder section bar exists complex structure, the big operation of coefficient of friction dumb, and intensity is low, connects unstable defective.
The purpose of this utility model is to overcome defective of the prior art, provides that a kind of simple in structure, flexible operation, intensity are good, long service life, good looking appearance, the aluminium alloys rolling door bottom girder section bar that is connected firmly.
The purpose of this utility model realizes by following technical proposals.
Aluminium alloys rolling door bottom girder section bar of the present utility model, form by bottom surface (1), supporting surface (2), open circles (3), transition inclined-plane (4), bottom surface (1) is the plane, and supporting surface (2) is edge-on on the plane, and the opposite side of supporting surface (2) links to each other with open circles (3) by transition inclined-plane (4).One end of the open circles (3) of aluminium alloys rolling door bottom girder section bar of the present utility model can be pegged graft with the curling hole of aluminium alloys roller shutter sheet section bar and be cooperated, and can be used for the fixing of various aluminium alloys rolling door.
In the such scheme, the internal diameter R=6mm of described open circles (3) is the distance L=9mm in open circles (3) outside from inboard to supporting surface (2) opposite side of supporting surface (2).
Profile design of the present utility model is reasonable, the junction cooperates closely, is difficult for threading off, and the characteristics that have simple in structure, better, long service life, good looking appearance, are connected firmly, thereby have good economic benefit and social benefit than filled circles conservation, flexible operation, intensity.
The utility model is described in further detail below in conjunction with accompanying drawing, but be not limited to shown in the accompanying drawing.
Fig. 1 is an aluminium alloys rolling door bottom girder transverse section of section material structural representation of the present utility model.
Among the figure: 1, bottom surface; 2, supporting surface; Open circles (3), transition inclined-plane (4).
As shown in Figure 1: aluminium alloys rolling door bottom girder section bar of the present utility model, form by bottom surface (1), supporting surface (2), open circles (3), transition inclined-plane (4), bottom surface (1) is the plane, supporting surface (2) one is edge-on on the plane, and the opposite side of supporting surface (2) links to each other with open circles (3) by transition inclined-plane (4).One end of the open circles (3) of aluminium alloys rolling door bottom girder section bar of the present utility model can be pegged graft with the curling hole of aluminium alloys roller shutter sheet section bar and be cooperated, and can be used for the fixing of various aluminium alloys rolling door.
The utility model can be processed into an integral body with bottom surface (1), supporting surface (2), open circles (3), transition inclined-plane (4) during making as shown in Figure 1.
In this example, the internal diameter R=6mm of open circles (3) is the distance L=9mm in open circles (3) outside from inboard to supporting surface (2) opposite side of supporting surface (2).The wide 70mm in bottom surface (1), thick 2mm, length are not limit.The high 65mm of supporting surface (2), thick 1.2mm.
The utility model is made the rolling door bottom girder because the employing aluminium alloys is a raw material, having overcome available technology adopting iron is that raw material making rolling door bottom girder gets rusty easily, the defective that the life-span is short, and this product is difficult for getting rusty, life-span is long, attractive in appearance more beautiful, will be subjected to people's welcome after putting goods on the market.。
Claims (2)
1, aluminium alloys rolling door bottom girder section bar, it is characterized in that forming by bottom surface (1), supporting surface (2), open circles (3), transition inclined-plane (4), bottom surface (1) is the plane, and supporting surface (2) is edge-on on the plane, and the opposite side of supporting surface (2) links to each other with open circles (3) by transition inclined-plane (4).
2, aluminium alloys rolling door bottom girder section bar according to claim 1 is characterized in that the internal diameter R=6mm of open circles (3), is the distance L=9mm in open circles (3) outside from inboard to supporting surface (2) opposite side of supporting surface (2).
