The door frame hinge mounting plate is characterized in that a bent angle A is connected with an arc-shaped forming surface, a bent angle B is connected with a rolled extension surface, and the other end of the rolled extension surface is connected with a deflection rolling surface to form an arc-shaped abdication notch; the door leaf half hinge is composed of a door leaf hinge mounting plate, a bent angle C, an inclined forming surface and a positive rolling round surface. The door leaf hinge mounting plate is connected with the inclined forming surface through a bent angle C, and the other end of the inclined forming surface is connected with the positive rolling round surface; the door leaf half hinge is connected with the door frame half hinge through a hinge mandrel, gaskets are arranged at the inner hole ends of the two rolling round parts of the door leaf half hinge, and two ends of the hinge mandrel are riveted or welded and fixed with two ends of the outer side of the rolling round part of the door leaf half hinge to form the special-shaped hinge. Because the hinge mandrel is connected with the two rolling round parts of the door leaf half hinge into a whole, the bearing capacity of the door leaf half hinge is greatly improved. The door frame half hinge is characterized in that at least two waist-round mounting holes and a plurality of opening slots are formed in a door frame hinge mounting plate. The hinge is convenient to install and debug.

The door frame half hinge, the T type axle sleeve is installed to its book circle portion outside both ends shaft hole in reaming, and the minor diameter end and the reaming tight fit of T type axle sleeve are connected fixedly, and the major diameter end and the gasket of T type axle sleeve offset the installation, constitute a function similar to plane bearing, avoid the direct door leaf half hinge shaft hole end running-in of T type axle sleeve terminal surface, wear the T type axle sleeve terminal surface easily.

In addition, a plurality of oil grooves which are towards the opening are designed on the gasket, and an inner hole of the gasket is tightly matched with the outer circle of the hinge mandrel to be connected and abutted against the inner hole ends of two rolling round parts of the half hinge of the door leaf to be fixed. Therefore, the hinge is durable, abnormal sound generated by the hinge is avoided, and the service life of the hinge is prolonged.

The utility model has the advantages that: the common exposed hinge is a hidden hinge, so that the appearance is attractive, the bearing capacity of the hinge is better than that of the exposed hinge, the manufacturing cost is lower than that of the exposed hinge, the surface electroplating cost of the exposed hinge is very high due to the exposed installation, and the bearing capacity of the exposed hinge is equal to that of the exposed hinge.
