Title: DOOR HINGE HAVING DAMPING FUNCTION
Abstract:
A door hinge having a damping function, comprising a housing (1), a first rotating shaft (2), a second rotating shaft (3), a U-shaped rotating shaft (4), a hinge cup (6), a linkage member (8), a torsion spring (5), a connector (7), a supporting structure (9), and a damping structure (10). One end of the linkage member (8) is rotatably provided in the housing (1) by mean of the first rotating shaft (2), and the other end of the linkage member (8) is rotatably connected to the hinge cup (6) by means of one arm (42) of the U-shaped rotating shaft (4); one end of the connector (7) is rotatably provided in the housing (1) by means of the second rotating shaft (3), and the other end of the connector (7) is rotatably connected to the hinge cup (6) by means of the other arm (41) of the U-shaped rotating shaft (4); the torsion spring (5) is fitted over the second rotating shaft (3), one end of the torsion spring (5) is fixed to the linkage member (8), and the other end of the torsion spring (5) abuts against the linkage member (8); the supporting structure (9) is fixed to the linkage member (8); the damping structure (10) is supported by the supporting structure (9) and moves in the housing (1) along with the supporting structure (9); a piston rod (101) of the damping structure (10) can abut against the torsion spring (5), so as to increase the resetting resistance to the torsion spring (5). The door hinge features a simple structure, a long service life, easy maintenance, and high precision.
