FIELD: refrigeration engineering.
SUBSTANCE: hinge and refrigeration equipment are disclosed. The hinge comprises a vertical hinge shaft, the first hinged base and the second hinged base. The first hinged base includes a first mounting plate and a first bushing rotatably coupled to the pivot shaft to allow the first bushing to rotate around the pivot shaft. The lower end of the first bushing is equipped with a first slope inclined downwards. The second hinged base located below the first hinged base includes a second mounting plate and a second bushing fixed to the hinged shaft. The upper end of the second bushing is equipped with an upwardly inclined second slope. The second slope rests against the first slope and interacts with it to enable the first sleeve to move from the first position to the second position in the direction from the second bushing or from the second position to the first position along the direction close to the second bushing when the first bushing rotates around the hinged shaft. The hinged shaft is equipped with the first restrictive groove, the first bushing is equipped with a restrictive protrusion extending into the first restrictive groove to limit the first bushing. Between the first restrictive groove and the end of the hinged shaft remote from the second bushing, a stopper is provided for abutting against the restrictive ledge, and a cutout is provided on the stopper near the upper end of the first restrictive groove, through which the restrictive ledge passes.
EFFECT: providing the possibility of automatic closing of the door under its own weight.
