Abstract
Description
Technical Field
[0001] This utility model relates to the field of factory door assembly structure technology, and in particular to the premium double-leaf door of the all-aluminum precision-carved armored door system. Background Technology
[0002] Armored doors originated in Italy. Their main characteristic is a sturdy steel structure in the center of the door panel, with both the front and back surfaces covered with a beautiful and easily replaceable finishing material, such as aluminum, copper, glass, composite wood, or solid wood. This design not only enhances security but also provides aesthetic appeal and fire resistance, achieving a dual-purpose function.
[0003] Structure and Design: Steel-wood armored doors use a steel security door as the basic core, utilizing the high plasticity of wood to encase the steel core, pursuing an elegant and balanced design style. This structure not only prioritizes aesthetics but also features resistance to deformation and cracking, moisture resistance, dampness prevention, sound insulation, and heat preservation.
[0004] Materials and processes: With the development of manufacturing technology, armored doors have adopted more advanced materials and processes. For example, instead of using traditional surface treatment methods, a layer of wood veneer is added to the surface of the steel entrance door. This not only ensures the security of the entrance door but also enhances its overall quality.
[0005] Market acceptance: In the past two or three years, armored doors have gained recognition and favor from a wide range of customers due to their advantages such as being heavy and imposing, durable, anti-theft and explosion-proof, corrosion-resistant and colorfast.
[0006] Existing armored doors have complex door panel structures, complicated installation procedures, and concentrated stress points, resulting in poor stability. Utility Model Content
[0007] The problem solved by this utility model is to provide a high-quality double-leaf armored door with an all-aluminum precision carving system, which solves the technical problems of existing armored door leaf structure being complex, installation steps being cumbersome, and stress points being concentrated, resulting in poor sturdiness.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] The all-aluminum precision-carved armored door is a double-leaf door with a mother door body and a daughter door body. Both the mother door body and the daughter door body include a door leaf frame, a first aluminum plate clip, a second aluminum plate clip, a door leaf lock material profile, a door leaf lock material cover plate, a sealing strip, and a small cover plate. The two door leaf frames of the mother door body are symmetrically arranged, and the two door leaf frames of the daughter door body are arranged in opposite directions.
[0010] The door frame is equipped with a first aluminum plate clip and a second aluminum plate clip respectively. A front and back panel is installed between the two first aluminum plate clips and between the two second aluminum plate clips of the main body of the mother door. A front and back panel is installed between the first aluminum plate clip and the second aluminum plate clip of the main body of the child door.
[0011] A door lock profile is installed on the middle of the outer side of the door frame, and a door lock cover plate is installed on the door lock profile.
[0012] A sealing strip is installed on the first aluminum plate clip, and a small cover plate is installed on the second aluminum plate clip.
[0013] Preferably, the door frame is fixedly connected to the first aluminum plate clip and the second aluminum plate clip by screws.
[0014] Preferably, the first aluminum plate has a slot, and a sealing strip is located in the slot, wherein the sealing strip is mushroom-shaped.
[0015] Preferably, the door frame and the door lock profile are fixedly connected by screws.
[0016] The beneficial effects of this utility model are: it disperses the stress points of the door, making it more robust and safer. It not only has anti-theft function, but also fireproof, explosion-proof, termite-proof and moisture-proof functions. It will never deform, is easy to assemble, and is integrally formed by changing the door leaf profile. Attached Figure Description
