Adjustable cover for drains that comprises a hollow base cylinder (1) fastened, by means of the vertical axis thereof, in a main-drain outlet, and an adjustable hollow cylinder (4) that supports an articulated drain cover (6) and can be fastened at different heights with respect to the base cylinder (1). The external diameter of the base cylinder (1) is slightly smaller than the internal diameter of the adjustable cylinder (4), and same are both arranged on the same axis, such that the adjustable cylinder (4) can slide, varying the position thereof around the base cylinder (1). Both cylinders comprise sets of circular segments (2, 5) arranged at complementary angles such that the adjustable cylinder (4) is able to slide on the base cylinder (1) and, when the desired height is achieved, by means of a rotation, the circular segments mesh together and fasten the adjustable cylinder (4). Furthermore, there are fastening holes (7, 8) and a safety fastening fitting (9). |
