The utility model relates to the technical field of suction discs for daily life, such as a suction disc and a suction disc hook device for attachment on glass or a smooth surface, in particular to the suction disc adhered on a flat surface. The suction disc comprises a suction disc column, a PVC (poly vinyl chloride) rubber sheet base and a sticky silica gel sheet. The suction disc is characterized in that the suction disc column is fixedly connected with the PVC rubber sheet base, and the lower part of the PVC rubber sheet base is connected with the sticky silica gel sheet; and one end of the suction disc column is connected with the PVC rubber sheet base, and the other end of the suction disc column is provided with a column hole. By the adoption of the suction disc, the problem that a common vacuum suction disc drops due to air leakage caused by non-uniform force bearing of the common vacuum suction disc can be effectively solved. |
