Description

Technical Field

[0001] The utility model relates to a detachable hinge, belonging to the category of hardware products. Background Art

[0002] The hinge is an important part of the door product. The existing hinges for anti-theft doors include two-section flag-shaped detachable hinges at the hinge shaft part and hinge structures with three or more sections. The hinge structure with three or more sections has the advantages that the hinge load is not easily deformed and the bearing capacity is strong, but the installation and use of the hinge are not convenient, and it is necessary to debug the clearance between the door frame and the door leaf. These debugging and fitting clearance operations are more professional for factory assemblers. However, for installers who install doors in society, they are not so professional and it will affect the installation quality of the door. The two-section flag-shaped detachable hinge structure has the advantage that after the clearance between the factory door frame and the door leaf is debugged, it is very convenient for users to install without adjusting the clearance between the frame and the leaf. Especially for high-end cast aluminum doors and engineering fire doors, the door leaf and the door frame are generally packed and installed separately, and the flag-shaped detachable hinge is very convenient to install. It will become increasingly important to design a hinge with both strong bearing capacity and convenient installation and debugging for customers. Summary of the Invention

The design of the buckling edge makes the connection between the fixed rotating part and the fixed part convenient and reliable.

[0006] Further: The plain bearing can be designed as a plain bearing structure composed of a T-shaped shaft hole sleeve plus a plain gasket or a steel ball plain bearing or a plain gasket.

[0007] Further: The first page plate includes a rotating part and a connecting plate, and a group of oval long-shaped mounting holes A or circular mounting holes C and an opening mounting hole B are provided on the connecting plate.

[0008] Further: The fixing part of the fixing member includes at least a set of oblong slots or circular mounting holes D.

[0009] Solution 2: It includes a first page plate, a second page plate assembly, a mandrel, and a plain bearing. The first page plate and the second page plate assembly are rotationally and movably connected through the mandrel. The plain bearing is installed at both ends of the shaft hole of the first page plate and abuts against the rotating shaft hole of the second page plate assembly. The second page plate assembly includes a rotating member, a fixing member, and a connecting screw. The rotating member is provided with a rotating shaft hole and a connecting part A. The fixing member is provided with a connecting part B and a fixing part. The connecting part B includes a first connecting plate A, a second connecting plate B, and a plugging groove B formed by the first connecting plate A and the second connecting plate B. The connecting part A is provided with a set of open connecting holes or square connecting holes or circular connecting holes C. The connecting part A and the connecting part B are connected and fixed by the connecting screw to fix the rotating member and the fixing member.
