Suction-cup-type anti-falling water cup

Abstract

The invention discloses a suction-cup-type anti-falling water cup, and relates to the field of water cups. The water cup comprises a cup body and a bottom cover; the bottom of the cup body is providedwith a concave cavity, and the concave cavity is internally provided with a rubber pad; the bottom cover comprises a locker, a suction cup and a base from bottom to top; a third through hole is formed in the radial middle portion of the locker, the top of the locker penetrates through a first through hole of the suction cup and is in threaded connection with a second through hole of the base, andthe suction cup is fixed between the locker and the base; a first lower limit hook is arranged on the upper portion of the base, the concave cavity is internally provided with a second lower limit hook corresponding to the first lower limit hook, and the second lower limit hook defines the lower limit position of the first lower limit hook. According to the water cup, when the water cup is placedon a plane, due to the self-weight of the water cup, the suction cup is pressed downwards to discharge air out through the third through hole and gaps, the cup body moves downwards to make the top ofthe locker in contact with the rubber pad, and a closed space is formed by the suction cup. At this moment, the water cup is unlikely to fall due to the function of the suction cup when the water cupis collided left and right.
