Knock-down prevention base of cup

Abstract

The invention relates to a knock-down prevention base of a cup. By the aid of the knock-down prevention base, the cup is difficult to knock down when placed on smooth object surfaces. The technical scheme includes that the knock-down prevention base of the cup comprises a cup base and a sucker. A movable block is concavely arranged on the bottom surface of the cup base, the side surfaces of the concave cup base are protruded towards the center of the concave cup base to form limiting protrusions, an exhaust cone vertex is arranged in the center of the bottom surface of the cup base, a sucker accommodating hole is formed in the middle of the movable block, the sucker is fixed into the sucker accommodating hole of the movable block, an air hole support is arranged on a suction zone of the sucker and is communicated with the inside of the cup base, and a conical radial opening is formed in the upper portion of the air hole support. The knock-down prevention base has the advantages that a conical air-tight door of the sucker is controlled by the aid of a sucker principle and mechanical force of the nature; the movable block can fall, so that air in the suction zone of a lower sucker can be exhausted to form a vacuum zone, the atmospheric pressure can tightly press the sucker on the object surfaces, and accordingly a cup body which is connected with the sucker can resist lateral thrust under the effect of the atmospheric pressure and can be prevented from being knocked down.

Description

technical field

[0001] This patent relates to an anti-falling base of a water cup, so that the water cup is not easy to be knocked over when placed on a smooth surface. Background technique

[0002] Because ordinary teacups are easy to be knocked over and broken in daily life, causing personal injury and trouble, if the teacup base is used, the problem that the teacup is easy to be knocked over and broken can be greatly reduced, thereby solving the objective problem of teacups being knocked over. But at present, because many untouchable teacups are designed to be cumbersome and inconvenient to use, and even change the appearance of the cups, the utilization rate is not high. Contents of the invention

[0003] The purpose of this patent is to provide an anti-fall base for water cups to solve the problem that the water cups are easy to be knocked over.

[0004] In order to achieve the above purpose, the technical solution adopted in this patent is: the water cup anti-fall b...
