Abstract

The utility model discloses a sucking disc, comprising a top 1, a main sucking disc body 2 and an auxiliary sucking disc body 3. The utility model is characterized in that the main and the auxiliary sucking disc bodies are the same shaft center, and the auxiliary sucking disc body 3 is smaller than the main sucking disc body 2 and is positioned at the lower part of the main sucking disc body 2; the position between the main and the auxiliary sucking disc bodies is provided with compression space 4, and the sucking disc with a double-layer structure is pressed on a smooth surface; the air in the inner part is extruded, and the outer part of the auxiliary sucking disc body is provided with the main sucking disc body, so that the air infiltration can be isolated and is absorbed by a double-layer disc surface; even if the air infiltrates the main sucking disc body, the position between the main and the auxiliary sucking disc bodies is provided with the compression space which elasticity is recovered to make the auxiliary sucking disc body pulled upwards; the hollowness at the inner part of the concave cavity is enlarged to enhance the adsorption force, and the sucking disc can not be loosened.

Description

A kind of sucker

The utility model relates to a kind of sucker, particularly double-deck sucker.

Existing sucker is a single layer structure, comprise top and sucker, cavity is formed on its bottom, sucker is pressed in a smooth surface downwards, and air squeezes in the cavity, and sucker just is absorbed and fixed on the smooth surface like this, but this sucker is subject to the influence of ambient air humidity and temperature contrast, make the sucker distortion, seal is poor, even gets loose from smooth surface.

The purpose of this utility model be to provide a kind of adsorption force by force, the sucker that do not get loose.

The sucker that the utility model proposes comprises top, main sucker and accessory sucker body, it is characterized in that major and minor sucker concentric, and the accessory sucker body is positioned at main sucker below less than main sucker, between the major and minor sucker compression volume is arranged.

Because sucker of the present utility model has said structure, main, accessory sucker body concentric, the accessory sucker body is less than main sucker, be positioned at main sucker below, main, between the accessory sucker body compression volume is arranged, this double-deck sucker is pressed on the smooth surface, main, the compressive strain of accessory sucker body, its inner air is squeezed, main, the card of accessory sucker body all is adsorbed on the smooth surface, because the accessory sucker external body has main sucker secluding air to infiltrate, double-deck card absorption is arranged again, adsorption force is strong, even and main sucker is subjected to ectocine, there is free air infiltration to become owner of sucker, and leads, between the accessory sucker body compression volume is arranged, opening of compression volume rebounded again, make on the accessory sucker body and draw, its cavity boring enlarges, thereby strengthens adsorption force, and sucker does not get loose.

The utility model will be further described below in conjunction with accompanying drawing and implementation column.

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the solid view of the utility model embodiment's suction.

With reference to Fig. 1, Fig. 2, the sucker that the utility model proposes, comprise top 1, main sucker 2 and accessory sucker body 3, it is characterized in that main, accessory sucker body concentric, accessory sucker body 3 are positioned at main sucker 2 belows less than main sucker 2, main, compression volume 4 is arranged between the accessory sucker body, this double-deck sucker is pressed on the smooth surface, main, the compressive strain of accessory sucker body, its inner air is squeezed, main, the card of accessory sucker body all is adsorbed on the smooth surface, because accessory sucker body 3 outsides have main sucker 2 secluding airs to infiltrate, double-deck card absorption is arranged again, adsorption force is strong, even and main sucker is subjected to ectocine, there is free air infiltration to become owner of sucker 2, and leads, compression volume 4 is arranged between the accessory sucker body, and opening of compression volume 4 rebounded again, can make on the accessory sucker body 3 and draw, its cavity boring enlarges, thereby strengthens adsorption force, and sucker does not get loose.

Claims

1, a kind of sucker, comprise top (1), main sucker (2) and accessory sucker body (3), it is characterized in that main sucker (2) and accessory sucker body (3) concentric, accessory sucker body (3) is less than main sucker (2), be positioned at main sucker (2) below, compression volume (4) is arranged between the major and minor sucker.
