Abstract
The invention discloses refrigerator door hinge mechanisms. The refrigerator door hinge mechanisms are arranged on a refrigerator body and a door cover respectively. Each hinge mechanism comprises a door hinge, a locking block and a locking shaft. The locking block and the locking shaft are arranged on the door cover and the door hinge respectively. The locking block is provided with a corner groove which is connected with the locking shaft in a clamping mode and limits the locking shaft. A rolling wheel is arranged at the initial contact ends of the locking block and the locking shaft. When the door cover is closed, the locking shaft makes contact with the locking block. The locking shaft presses the rolling wheel. Angular deformation occurs to the initial contact end of the locking block in the clockwise direction, so that the locking shaft enters the corner groove along with rotation of the rolling wheel. Through deformation of the locking block, the locking block is in interference fit with the locking shaft, so that the function of locking of a refrigerator door is achieved, and cold air in a refrigerator is prevented from leakage. The rolling wheel is arranged at the front contact end of the locking block, so that contact friction is made to be in the rolling form, friction is reduced, and the service life of the hinge mechanisms is ensured.
