<p>A vacuum suction having a flat skeleton comprises a flat skeleton (1), a suction cup (2) covering the skeleton (1), a connection rod (101) disposed on a back surface of the skeleton (1) and penetrating the suction cup (2), a suction cup cover (3) sleeved on the connection rod (101) and covering a back surface of the suction cup (2), and a pressing component (51, 52) disposed on a back surface of the suction cup cover (3) and connected to the connection rod (101). A sealing component (16) is disposed on an adsorption surface of the suction cup (2). A convex ring (301, 302, 303) is disposed on an internal surface of the suction cup (2) and is used to press a corresponding position of the back surface of the suction cup (2) and the sealing component (16). Because of rigid force transferring, the effect of force transferring is desirable, the sealing component (16) can incease the airtightness of a vacuum chamber, and increase the absorption force of the suction cup. During vacuumizing, the skeleton matches the sealing component (16) so that the air cannot easily enter the vacuum chamber, and because the skeleton (1) is flat shaped before vacuumizing, the vacuum suction cup has high vacuumizing degree and large absorption force, and do not easily fall off; moreover, the vacuum suction cup has a simple structure and low cost.</p> |
