[0035] During installation, the fixed seat 2 is installed on the door frame, and the movable seat 1 is installed on the door leaf. According to the actual installation situation, the hinge position is adjusted by adjusting the two upper and lower adjustment cams 234 to achieve relative displacement between the fixed seat base 23 and the fixed seat base 22, so as to achieve the purpose of adjusting the upper and lower gaps between the door frame and the door leaf; the front and rear adjustment cams 27 are adjusted to drive the fixed seat bracket 24 to move left and right on the fixed seat base 22 to achieve the front and rear adjustment of the door leaf and adjust the front and rear gaps between the door frame and the door leaf; the movable seat left and right adjustment screws 14 are adjusted to drive the movable seat bracket 13 to move up and down in the movable seat shell 12 to achieve the left and right adjustment of the door leaf and adjust the left and right gaps between the door frame and the door leaf. The present invention places the adjustment position of the three-dimensional adjustment on the surface, which is convenient and quick to adjust; in the case of the commonly used door thickness (40-45mm), the openings of the door frame and the door leaf can be centered, which reduces the difficulty of opening the holes.

[0036] The hinge internal connecting rod articulation structure forms two four-bar linkages through the articulation between the movable side swing arm 31, the center swing block 32, the fixed side swing arm 33, the fork swing arm 34, the movable seat bracket 13 and the fixed seat bracket 24. Through corresponding calculation and design, it is ensured that the corresponding door opening angle is achieved. At the same time, after the door is closed, the hinge is closed, and the swing arm can be hidden inside the movable seat shell 12 after contraction, which can reduce the opening depth of the door frame, ensure the strength of the door frame, and reduce the processing amount.

[0037] The connection between the swing arm and the hinge bracket and between the swing arms are isolated with nylon gaskets 312 to increase wear resistance and achieve a silent effect; there are cover plates on the exterior surfaces of both ends of the hinge to prevent dust and other debris from entering the hinge and increase the aesthetic effect of the hinge.

[0038] The invention has the advantages of simple structure, low manufacturing cost, convenient assembly, strong processability, convenient use, high reliability and good industrialization prospect.
