A vacuum suction cup having a bowl-shaped skeleton comprises a bowl-shaped skeleton (1), a suction cup (2) covering the skeleton (1), a connection rod (11) disposed on a back surface of the skeleton (1) and penetrating the suction cup (2), a suction cup cover (3) sleeved on the connection rod (11) and covering a back surface of the suction cup (2), and a pendant (5) disposed on a back surface of the suction cup cover (3) and connected to the connection rod (11). An annular rib (12) is disposed on the periphery of the back surface of the skeleton (1), and an internal surface of the suction cup cover (3) presses against the annular rib. When being pressed, the annular rib (12) can effectively transfer the pressing force, so that the suction cup does not easily fall off. |
