[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a single-door structure with a cover edge, comprising:

[0004] A door frame, at least partially bent to form a first mounting portion for installation into an opening in a wall; the door frame comprises four cold-rolled steel plates, adjacent cold-rolled steel plates being welded together by a V-shaped welding process, the cold-rolled steel plates being bent to form the first mounting portion.

[0005] The door leaf is rotatably connected to the door frame via a rotating connector. The door leaf includes a first steel member and a second steel member located on both sides, a foam layer filled between the first steel member and the second steel member, and a thickness connecting plate connecting the four sides of the first steel member and the second steel member. A decorative panel is fixed to the outer surface of the first steel member and the second steel member.

[0006] A steel cover is fixed to the outside of the door leaf near the door frame, and the steel cover and the rotating connector are respectively located on both sides of the door leaf.

[0007] Through the above technical solution, this utility model is equipped with a steel cover edge, wherein a sealing strip, such as a silicone strip, can be fixedly installed on the inner side of the cover edge to increase the sealing effect and prevent air leakage.

[0008] The first steel, the foam layer, and the second steel are hot-pressed together.

[0009] The first steel piece and the thickness connecting plate, and the second steel piece and the thickness connecting plate are welded together using a V-welding process. The thickness connecting plate is formed by bending either the first steel piece or the second steel piece.

[0010] The rotating connector includes a hinged first page and a second page. The first page also passes through the door frame and is connected by fasteners. The second page has a bent portion that mates with the door leaf. The second page is connected to the thickness connecting plate of the door leaf by fasteners.

[0011] The inner wall of the door frame has an inwardly punched recess, and the first page is installed in the recess by fasteners.

[0012] The door frame and door leaf are equipped with matching lock slots and locks. The steel cover edge is located on the lock side and above the door leaf. The steel cover edge has bent protrusions.

[0013] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and is easy to install. For example, the door frame of this utility model can be fixed to the door opening with fasteners, and then the door leaf can be installed by rotating the connector. The style of the decorative panel can be changed according to the customer's choice. Attached Figure Description
