Specifically, as shown in fig. 2 to 8 and fig. 10 to 15, the hinge with the rotation buffer structure includes a hinge cup 1, a hinge arm 2, and a base 3. The hinge cup 1 is used for being connected with the door body, and the hinge cup 1 can be screwed on the door body in a screw mode so as to realize the fixed connection of the hinge cup 1 and the door body; the base 3 is used for being connected with the cabinet body, and the base 3 can be screwed on the cabinet body in a screw mode so as to realize the fixed connection between the base 3 and the cabinet body; the hinge arm 2 is used for being connected between the hinge cup 1 and the base 3. In particular, a concave cavity 11 is arranged on the hinge cup 1, one end of the hinge arm 2 is hinged in the concave cavity 11, and a buffer structure is arranged between the hinge arm 2 and the concave cavity 11, so that buffer rotation is realized when the hinge cup 1 rotates relative to the hinge arm 2.

Therefore, the hinge arm 2 is hinged in the concave cavity 11, and the buffer structure is arranged between the hinge arm 2 and the concave cavity 11, so that a user can have the effect of buffering rotation when the door body is closed or opened by rotation.
