[0004] A flag hinge comprises a door frame leaf plate assembly, a door leaf plate assembly and a plane bearing. The door frame leaf plate assembly comprises a door frame leaf plate, a core shaft, a decorative sleeve A and a decorative end cap A; the door leaf plate assembly comprises at least a door leaf plate), a decorative sleeve B and a decorative end cap B; the core shaft passes through the shaft hole A of the door frame leaf plate and is fixed with the shaft hole A by interference fit; the plane bearing is arranged at the end face of the shaft hole A of the door frame leaf plate and the end face of the shaft hole B of the door leaf plate and is installed against each other; the decorative sleeve A and the decorative sleeve B are respectively arranged at the outer side of the rolled shaft hole of the door frame leaf plate and the door leaf plate, the decorative end cap A and the decorative end cap B are respectively arranged at the lower end of the shaft hole A of the door frame leaf plate and the upper end of the shaft hole B of the door leaf plate and are connected and fixed with the rolled shaft hole A and the rolled shaft hole B by interference fit; the shaft hole B of the door leaf plate assembly is plugged with the core shaft and is connected with the core shaft by rotation fit to form a flag hinge.

[0005] The outer surfaces of the decorative sleeves A and B are provided with decorative textures or smooth and glossy structures. Designing the decorative sleeves A and B can make the hinge look beautiful, just like giving the hinge different clothes and different appearances, which can make the appearance diverse.

[0006] Further: the plane bearing is a plane bearing composed of two plane washers sandwiched with a brass sheet, or a steel ball plane bearing, or a plane washer. The plane bearing composed of two plane washers sandwiched with a brass sheet can improve the bearing capacity of the hinge.

[0007] Furthermore: the fixing plate A of the door frame leaf plate is provided with a group of transverse or longitudinal mounting holes and at least one circular fixing hole.

[0008] Furthermore: the fixing plate B of the door leaf plate is provided with at least a plurality of circular countersunk holes or waist-shaped oblong countersunk holes.

[0009] Furthermore: the door frame leaf plate includes a core shaft B and a leaf plate A, and the core shaft B and the leaf plate A are fixed by welding.

[0010] Furthermore: the door leaf plate can be a welding structure of a sleeve and a leaf plate B or an integrally rolled structure.

[0011] Furthermore: the decorative cover A and the decorative cover B are decorative covers of any shape structure of the integral decorative cover C without the decorative end cover A or the decorative end head B.

[0012] In summary, the utility model has the following beneficial effects: first, the design of the decorative end sleeve and the decorative end head makes the hinge look good, and the hinge can be diversified by changing the appearance of the decorative end sleeve. Second, the hinge can separate the door leaf from the door frame, and the door leaf can be quickly disassembled and installed. BRIEF DESCRIPTION OF THE DRAWINGS
