AI Technical Summary
Hinges and hinges in container houses are susceptible to damage from wind and rain when used outdoors, especially in temporary outdoor structures.
The design employs two semi-enclosed flaps that interlock to form a concealed hinge, ensuring that the hinge column remains enclosed within the interior during opening and closing, preventing it from being exposed.
This significantly reduces the risk of rainwater erosion of the hinge joints, improving the durability and corrosion resistance of the hinges.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a concealed hinge steel door for a box-type house. Background Technology
[0002] Typically, the moving or hinged panels of steel doors are connected to the wall or door frame via hinges, enabling the opening and closing of the panels. As is known, a hinge consists of two leaves and a hinge post. Regardless of whether the hinge is installed on the outside, inside, or edge of the door, the hinge post is exposed to the elements in at least one of the open or closed states. The hinge post bears the weight of the moving or hinged panel and is subjected to friction from rotation; therefore, it and its associated components are highly susceptible to damage from wind and rain. Furthermore, container houses are often used as temporary outdoor structures, such as prefabricated houses, mobile hospitals, and mobile laboratories. Without the shelter of larger buildings, they are more vulnerable to wind and rain than ordinary residences. Therefore, it is necessary to design a hinge and steel door that can protect the hinge post. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this utility model provides a concealed hinged steel door for box-type houses.
[0004] The technical solution of this utility model is as follows:
[0005] A concealed hinged steel door for a box-type house includes a door frame, a first hinge, a second hinge, and a door leaf;
[0006] The first page includes a first fold, a second fold, a third fold, a fourth fold, a fifth fold, a sixth fold formed by bending a metal plate, and a first hinge post welded to the sixth fold;
[0007] The second page includes the seventh, eighth, ninth, tenth, eleventh, and twelfth folds formed by bending metal plates, and the second hinge post welded to the twelfth fold;
[0008] The first hinge post and the second hinge post are hinged together by a hinge axis;
[0009] The first fold is connected to the door frame by bolts, and the seventh fold is connected to the door leaf by bolts.
[0010] In a preferred embodiment of this disclosure, the first fold and the second fold are arranged perpendicularly, the third fold is arranged inwardly, the fourth fold is arranged outwardly, the fifth fold is arranged outwardly, and the sixth fold is arranged outwardly, with the six folds together forming a semi-enclosed structure.
[0011] In a preferred embodiment of this disclosure, the seventh fold is arranged parallel to the first fold, the eighth fold is inclined inward, the ninth fold is inclined inward, the tenth fold is inclined inward, the eleventh fold is inclined outward, and the twelfth fold is inclined outward, with the six folds together forming a semi-enclosed structure.
[0012] In a preferred embodiment of this disclosure, both the door frame and the door leaf are made of one of cold-rolled steel, hot-rolled steel, or stainless steel. This ensures strength and provides a certain degree of rust resistance.
[0013] In a preferred embodiment of this disclosure, the first page, the second page, and the hinge shaft connecting them are all made of either stainless steel or aluminum alloy. This provides sufficient support and is wear-resistant and corrosion-resistant.
[0014] Beneficial effects of this utility model
[0015] According to this disclosure, a concealed hinge is constructed using two semi-enclosed flaps. By utilizing their interlocking structure, the hinge pins and hinge axis are not exposed to the outside when the steel door is open, closed, or in the middle state, which greatly reduces the probability of rainwater eroding the hinge pins.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:
[0021] In this embodiment, both the door frame and the door leaf are made of stainless steel. The first page, the second page, and the hinge shaft connecting them are also made of stainless steel.
[0022] like Figure 1 and 2 As shown, a concealed hinged steel door for a box-type house includes a door frame 1, a first page 2, a second page 3, and a door leaf 4;
[0023] The first page 2 includes a first fold 21, a second fold 22, a third fold 23, a fourth fold 24, a fifth fold 25, a sixth fold 26 formed by bending a metal plate, and a first hinge post 27 welded to the sixth fold 26; the second page 3 includes a seventh fold 31, an eighth fold 32, a ninth fold 33, a tenth fold 34, an eleventh fold 35, a twelfth fold 36 formed by bending a metal plate, and a second hinge post 37 welded to the twelfth fold 36; the first hinge post 27 and the second hinge post 37 are hinged by a hinge shaft (a conventional hinge structure, not shown); the first fold 21 is connected to the door frame 1 by bolts (conventional technology, not shown), and the seventh fold 31 is connected to the door leaf 4 by bolts (conventional technology, not shown).
[0024] The first fold 21 is perpendicular to the second fold 22. The third fold 23 is inclined inward, the fourth fold 24 is inclined outward, the fifth fold 25 is inclined outward, and the sixth fold 26 is inclined outward. The six folds together form a semi-enclosed structure. The seventh fold 31 is parallel to the first fold 21. The eighth fold 32 is inclined inward, the ninth fold 33 is inclined inward, the tenth fold 34 is inclined inward, the eleventh fold 35 is inclined outward, and the twelfth fold 36 is inclined outward. The six folds together form a semi-enclosed structure.
[0025] like Figure 1 and 3 As shown, the hinge post in this invention is always enclosed and not exposed to the elements, whether the door is open, closed, or in the middle position, due to the protection of the two semi-enclosed structures of the first page 2 and the second page 3. Therefore, it is not easily exposed to rainwater. Obviously, this invention can also provide a shielding mechanism for the top of the hinge post, but this mechanism is a conventional component and will not be described in detail here.
[0026] Although a steel door according to an embodiment of the present disclosure has been described above, aspects of the present disclosure are not limited to the above embodiments, and the present disclosure can be implemented in a variety of ways within the scope of the present disclosure.
