Door opening and closing hinge with strong directional fixation function
The invention discloses a door opening and closing hinge with a strong directional fixation function. The door opening and closing hinge comprises a hexagon nut, a first movable leaf, bevel tooth cylindrical gears, springs, a second movable leaf and a circular bolt, wherein a rotating shaft portion of the second movable leaf is provided with a first inner cavity, an inner cavity partition wall and a second inner cavity. The bevel tooth cylindrical gears and the springs are symmetrically arranged in the first inner cavity and the second inner cavity; gears are arranged on the inner wall of the first inner cavity and the inner wall of the second inner cavity, and used for being in meshing connection with the bevel tooth cylindrical gears; the first movable leaf and the second movable leaf are connected together in a rotatable mode through the hexagon nut after the circular bolt penetrates through a rotating shaft of the first movable leaf and a rotating shaft of the second movable leaf. The door opening and closing hinge can achieve the function that opening and closing is achieved at any positions within the angle of 90 degrees of the hinge, parts used by the door opening and closing hinge are free of the requirements for special materials, and the door opening and closing hinge is particularly applicable to door opening and closing structures which have the requirement for the angle of the door opening and closing working space.
