[0002] Many cities in our country are vigorously developing rail transit. The demand for AFC products has increased sharply. At places such as subway automatic ticket gates and intelligent side doors, attention needs to be paid to the hinges at the connection between the doors of the equipment and the door frames. Hinges belong to a kind of connecting piece, generally composed of two components through a movable rotating shaft. It can be used to connect two parts of an object and enable one part to rotate within a certain range with the rotating shaft as the center of the circle. It is an industrial manufactured product made of metal materials with good stiffness and toughness.

[0003] Existing hinges usually only function as the installation and movable connection of door panels. During long-term opening and closing, the deformation of the opening and closing doors is likely to be caused by pressure or wear. The overall bearing capacity and durability of the hinges are relatively insufficient, and they cannot well adapt to the long-term wear resistance of opening and closing. Moreover, when the hinges are replaced and repaired, their adjustment capabilities in the four directions of left, right, up, and down are relatively insufficient. It is impossible to conveniently control the gap of the maintenance door, the gap of the maintenance door is unevenly installed, and the adjustment is relatively difficult. The convenience of later adjustment and maintenance is insufficient. Both the durability in the early stage and the convenience of later maintenance are relatively insufficient. The deformation and assembly gap problems of the maintenance door will affect the maintenance and appearance quality of the equipment. Therefore, we propose an adjustable hinge to solve the above problems. Content of the Utility Model
