Full-aluminum alloy anti-theft entrance door

Abstract

The invention discloses a full-aluminum alloy anti-theft entrance door. The door comprises a door frame, a door leaf, and a hinge connecting the door frame with the door leaf; The door is characterized in that the door leaf comprises a door leaf upper transverse material, a door leaf lower transverse material, a plurality of door leaf vertical materials and a pull rod, two ends of each door leaf vertical material are fixedly connected with the door leaf upper transverse material and the door leaf lower transverse material correspondingly, and the pull rod penetrates through the door leaf vertical materials and is fixedly connected with the door leaf vertical materials; and each door leaf vertical material comprises inner and outer profiles, and the two profiles of each door leaf vertical material are connected and isolated through a heat insulation strip. The door leaf is formed by assembling the door leaf upper transverse material, the door leaf lower transverse material, the plurality of door leaf vertical materials and the pull rod of aluminum alloy profiles, so that machining is convenient, production precision is high, profiles are connected through assembling without welding,machining is convenient, and mounting and transporting are convenient; and in addition, each door leaf vertical material comprises inner and outer profiles, and the two profiles of each door leaf vertical material are connected and isolated through the heat insulation strip, so that the heat insulation and sealing performance of the whole door leaf is very excellent.

Description

Technical field [0001] The invention relates to the technical field of anti-theft doors, in particular to an aluminum alloy combined heat-insulating anti-theft entrance door. Background technique [0002] At present, the entrance doors used in the construction industry mainly include iron doors, copper doors, stainless steel doors, and armored doors, each of which has the following disadvantages: [0003] 1) Iron and copper entrance doors: rust and discoloration will appear after using for a period of time, which will affect the appearance of the entire door; the shape lines are too hard and are incompatible with modern home decoration styles. In addition, the density of copper and iron is high, and the weight of the door is heavier, which is not conducive to installation and transportation. [0004] 2) Stainless steel entrance door: The color is single, basically silver-white, and the appearance and color are somewhat monotonous, which makes people feel more rigid. [0005] 3) Armor...

AI Technical Summary

Problems solved by technology

[0003] 1) Iron and copper entrance doors: rust and discoloration will occur after a period of use, affecting the appearance of the entire door; the styling lines are too hard, which is very inconsistent with the modern home decoration style

In addition, the density of copper and iron is relatively high, and the weight of the door is relatively heavy, which is not conducive to installation and transportation

[0004] 2) Stainless steel entrance door: the color is single, basically silver-white, giving people the feeling that the appearance and color are a bit monotonous, which makes people feel relatively blunt

[0005] 3) Armored door: The surface of the steel entrance door is covered with a layer of door panels. Although the appearance is beautiful, the cost is high. The wooden panels covered on the surface are easily damaged and not easy to replace

[0006] In addition, iron, copper, stainless steel, and armored doors all have high raw material density and low recycling value; the profiles cannot be used as heat-insulating bridge structures, and the heat insulation performance is poor; the installation accuracy is not high, and the sealing performance is poor. question
