The patent abstract shows that this application provides an automatically resilient door hinge and a freezer. The door hinge includes: a first mounting plate, a second mounting plate, a spring leaf and a pin. The first mounting plate is hingedly connected to the second mounting plate through a pin; the spring leaf has an arc-shaped structure, and a first limiting shaft and a second limiting shaft are respectively provided on the sides of the first mounting plate and the second mounting plate. Both ends are hinged with the first limiting shaft and the second limiting shaft respectively. Fix the first mounting plate and press the second mounting plate so that the first mounting plate and the second mounting plate are at a preset angle. The spring leaf is compressed. Remove the external force pressing the second mounting plate. The spring leaf will automatically move under the action of elastic force. Rebound and regain freedom. By setting door hinges on the freezer door, the door can automatically hover. When assembling the door hinge, you only need to install three shaft structural parts and three plate structural parts.
