The invention discloses a hinge for a door body of a horizontal refrigerator, which comprises a hinge head and a hinge seat; a hinge shaft and a movable shaft are hinged on the hinge head; a support seat is arranged at the lower part of the hinge seat, and a support plate is movably inserted in the middle part of the support seat; There is a compression spring; a damper is arranged outside the arc channel on at least one side of the hinge seat; the damper includes a damper body, an arc guide rail, a damping chamber, a damping cylinder cover, a damping rod, a piston, a first chamber, and a second chamber chamber, damping spring, pressure plate, and damping end block; the first chamber and the second chamber are filled with non-Newtonian fluid, and the chamber between the pressure plate and the damping end block is filled with hydraulic oil. The structural setting of the hinge of the present invention, when the door is closed, the compression spring, the damping spring in the damper, and the non-Newtonian fluid in the first chamber form multiple damping, which can prevent the door from falling rapidly and reduce the impact on the cabinet. Body damage, but also reduce the noise.
