Abstract
Disclosed are a hinge and a refrigeration equipment. The hinge includes a vertical hinge shaft, a first hinge base and a second hinge base. The first hinge base includes a first installation plate and a first sleeve rotatably connected to the hinge shaft to make the first sleeve rotate around the hinge shaft. A lower end of the first sleeve is provided with a first slope sloping downwards. The second hinge base below the first hinge base includes a second installation plate and a second sleeve fixed on the hinge shaft. An upper end of the second sleeve is provided with a second slope sloping upwards. The second slope abuts against and cooperates with the first slope for the first sleeve to move from a first position to a second position along a direction away from the second sleeve or from the second position to the first position along a direction close to the second sleeve while being rotated around the hinge shaft.
