Description

sucker

The present invention is related to suction cups.

The principle of the suction cup is related to the air pressure. By extruding the air under the adsorption surface, the pressure inside the adsorption surface is lower than that of the outside and is supported by the top, so that the suction cup can be adsorbed on the smoother surface of the object. With this feature, the suction cup can be easily positioned on the wall without damaging the wall, and the position can be changed arbitrarily according to the needs. In daily life, the suction cup is mostly used as a connecting device for suspension, and in construction work, Suction cups are often used to carry large items, such as glass.

The characteristics of the suction cup can be further applied to other engineering operations, such as tile leveling. The traditional tile leveling method is measured by a level meter, and the required flatness can only be achieved through repeated operations and adjustments. The operation is too complicated and Correction time is lengthy. The other method is to place a disposable tile leveler at the same time as laying the tiles. This method requires a lot of leveler consumables, which is not only not environmentally friendly, but also requires a lot of space for storage.

Therefore, it is necessary to provide a novel and progressive suction cup to solve the above problems.

The main purpose of the present invention is to provide a suction cup that can be positioned behind the tiles and press the surrounding tiles through the pressing unit to achieve the purpose of leveling the tiles. Moreover, the structure of the universal joint can make the angle of the pressing member change correspondingly with the inclination of the tiles, so as to positively press the tiles positively and have a better flat surface.

To achieve the above object, the present invention provides a suction cup, comprising: a main body unit and a pressing unit. The main body unit includes a connected base and an adsorption surface; the pressing unit includes a manipulation piece, a universal joint and a pressing piece, the manipulation piece can be movably arranged on the base, and the universal joint connects The control member and the pressing member, and furthermore, the pressing member can swing relative to the operating member.

The following examples illustrate the possible implementation of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" before the nouns mentioned in the text do not limit the number. According to the needs, it can be "single" or "plural", and the change in this number is also the scope of protection, which will be described first.
