[0005] This utility model adopts the following technical solution: a corrosion-resistant butt hinge, comprising two U-shaped structures, four positioning structures, and a central seat, wherein:

[0006] The U-shaped structure has a U-shaped body and two U-shaped arms that are integrally formed with the U-shaped body. The U-shaped arms have U-shaped arm alignment holes.

[0007] The positioning structure includes a first positioning body and a second positioning body coaxially distributed with the first positioning body, wherein the second positioning body is partially connected to the first positioning body;

[0008] The center seat has a center seat cavity and multiple center seat alignment holes that communicate with the center seat cavity respectively. The first positioning body is connected to the center seat alignment hole and extends further into the center seat cavity. The second positioning body is connected to the U-shaped arm alignment hole and extends further into the center seat cavity.

[0009] As a preferred technical solution of the above technical solutions, the first positioning body is provided with a first positioning disk and a first positioning ring integrally formed with the first positioning disk.

[0010] As a preferred technical solution of the above technical solutions, the second positioning body is provided with a second positioning disk and a second positioning post and a second positioning post extension integrally formed with the second positioning disk. The second positioning post is internally connected to the alignment hole of the U-shaped arm, and the second positioning post extension is internally connected to the first positioning body.

[0011] As a preferred embodiment of the above technical solutions, the inner diameter of the second positioning post is larger than the inner diameter of the extension of the second positioning post.

[0012] As a preferred technical solution to the above technical solutions, the outer surfaces of the U-shaped structure, the positioning structure, and the center seat are respectively provided with a corrosion-resistant layer.

[0013] The corrosion-resistant butt hinge disclosed in this utility model has the advantage that the swing directions of the two U-shaped structures are not the same, thereby enabling the corrosion-resistant butt hinge to connect to the external structure in two different directions.

[0024] Example 1.

[0025] Preferably, the corrosion-resistant butt hinge includes two U-shaped structures 100, four positioning structures 200, and a center seat 300, wherein:

[0026] The U-shaped structure 100 is provided with a U-shaped body 110 and two U-shaped arms 120 integrally formed with the U-shaped body 110, and the U-shaped arms 120 have U-shaped arm alignment holes 121.

[0027] The positioning structure 200 includes a first positioning body 210 and a second positioning body 220 coaxially distributed with the first positioning body 210, wherein the second positioning body 220 is partially connected to the first positioning body 210.

[0028] The center seat 300 has a center seat cavity 302 and a plurality of center seat alignment holes 301 that are respectively connected to the center seat cavity 302. The first positioning body 210 is connected to the center seat alignment hole 301 and further extends into the center seat cavity 302. The second positioning body 220 is connected to the U-shaped arm alignment hole 121 and further extends into the center seat cavity 302.

[0029] This allows one of the U-shaped structures 100 to swing relative to the center seat 300, and the other U-shaped structure 100 to swing relative to the center seat 300, with the two U-shaped structures 100 swinging in different directions, thereby achieving the effect that the corrosion-resistant butt hinge can be connected to the external structure in two different directions.

[0030] The outer surfaces of the U-shaped structure 100, the positioning structure 200, and the center seat 300 are respectively provided with corrosion-resistant layers (not shown in the figure).

The second positioning post 222 is connected to the U-shaped arm alignment hole 121, and (partially) the second positioning post extension 223 is connected to the first positioning body 210 (i.e., it is simultaneously connected to the first positioning disk 211 and the first positioning ring 212).

[0033] The inner diameter of the second positioning post 222 is larger than the inner diameter of the second positioning post extension 223, which facilitates alignment and stable connection.

[0034] The first positioning ring 212 has multiple first positioning ring holes 213, and the second positioning disk 221 has multiple second positioning disk holes 224, so as to achieve the functions of weight reduction or positioning and fixing.
