1. A door assembly for a refrigerator, comprising two oppositely arranged doors and a turnover beam assembly, wherein the turnover beam assembly comprises:
a turnover beam body configured to be provided on one of the doors in a turnover manner by a pivoting part;
a guide part extending out of one end of the turnover beam body and configured to be fitted with a retainer provided on a cabinet of the refrigerator;
a locking part telescopically provided in the turnover beam body and having a first end fixedly connected with the guide part and a second end having a locking portion for limiting turnover of the turnover beam body, the locking part being configured to have a retracted unlocking state and an extended locking state, and when the locking part is in the unlocking state, the locking portion abutting against a stopping portion provided on the pivoting part; and
an elastic part configured to apply, to the locking part, an elastic pre-tightening force for urging the locking part into the locking state; and the turnover beam assembly is configured such that:
when the door where the turnover beam body is located is closed, the guide part is pressed down by the retainer to keep the locking part in the unlocking state; and
when the door where the turnover beam body is located is opened and after the guide part is separated from the retainer, the locking part is in the locking state under an action of the elastic pre-tightening force;
wherein the turnover beam body is provided with a telescopic hole for the guide part to extend out, at least one part of a circumference of the telescopic hole is convexly provided with a reinforcing rib, and the reinforcing rib is attached to a section of the guide part extending out of the telescopic hole, so as to prevent the guide part from shaking in the process of fitting with the retainer;
wherein a guide groove is further formed in the reinforcing rib; and
a guide projection is further formed on a surface of the guide part facing the reinforcing rib, and the guide projection is fitted with the guide groove to limit a moving track of the guide part.
