Embodiment Construction

[0018] Embodiments are described below with reference to the drawings.

[0019] Such as figure 1 As shown, the suction cup of the present invention includes a suction part 1 , a suction cover 2 and a locking part 3 . Adsorbent 1 includes colloid 11, extruding block 12, extruding plate 13 and connecting rod 14; colloid 11 includes tentacles one 111, tentacles two 112 and tentacles three 113; extruding block 12 includes extruding block one 121, extruding Briquetting block two 122 and extruding block three 123. Tentacles one, two and three (111, 112, 113) on the colloid 11 are formed as a whole, and are made of elastic soft plastic; Substrate (such as wall, glass substrate) contact; such as figure 2 As shown, tentacles one, two and three (111, 112, 113) are distributed on the circumference and form a closed ring shape; there is a space formed in tentacles one, two and three (111, 112, 113), and the space Can hold air inside. Such as figure 1 As shown, extrusion blocks 1, 2...

Abstract

The invention relates to a suction disc, which comprises an adsorption element, an adsorption cover and a locking element, wherein the adsorption element comprises colloid, extrusion blocks, an extrusion plate and a connecting rod; the colloid comprises a first tentacle, a second tentacle and a third tentacle; the extruding block comprises a first extrusion block, a second extrusion block and a third extrusion block; the first, second and third tentacles are in contact with the adsorbed base surface; a space is formed in each of the first, second and third tentacles; the air can be accommodated in the space; the first, second and third extrusion blocks are arranged above the colloid and are connected with the colloid; the first, second and third extrusion blocks are respectively and correspondingly arranged on spaces formed by the first, second and third tentacles. After the suction disc provided by the invention is used, the adsorption time of the suction disc with the base surface can be increased; the air inlet the suction disc can be effectively extruded, so that the inside air pressure is smaller than the external barometric pressure.

Description

technical field [0001] The invention relates to a novel sucker. Background technique [0002] The suction cup has become a well-known product. When using it, it is adsorbed on the wall, glass and other base surfaces, and then hang calendars, towels and other items on it. It is very convenient and quick to use, and can be removed when not needed. The working principle of the suction cup is: when it is in contact with the wall, glass and other base surfaces, the air between the suction cup and the base surface is squeezed away, and the internal atmospheric pressure is lower than the external atmospheric pressure, so the external atmospheric pressure presses it on the base surface. [0003] The sealing ring on the suction cup in the prior art protrudes from the surface of the elastic colloid. When used on a smooth surface, the sealing ring on it first contacts the base surface, and presses against the suction cup cover as the connecting piece and the connecting rod cooperate. ...
