The invention relates to the technical field of refrigerators of household electrical appliances, in particular to an embedded refrigerator door hinge with a sliding block. The embedded refrigerator door hinge comprises an inner fixed plate, an outer fixed plate, an inner swinging rod and an outer swinging rod, wherein the inner swinging rod and the outer swinging rod are connected with the innerfixed plate and the outer fixed plate; the inner swinging rod is connected with the inner fixed plate through a first inner swinging rod shaft and connected with the outer fixed plate through a second inner swinging rod shaft; the outer swinging rod is connected with the inner fixed plate through a first outer swinging rod shaft and connected with the outer fixed plate through a second outer swinging rod shaft; and the inner fixed plate is connected with a sliding block locking mechanism which can generate elastic stretching when the door body is pushed. By designing the embedded door hinge self-locking mechanism, the invention solves the problem of stress concentration of the door hinge on the basis of realizing embedded door body self locking, effectively reduces the probability of doorhinge breakage, improves the seal performance of the embedded household electrical appliance door body during closing and prolongs the service life.
