Abstract: Provided are a suction cup and a vacuum suction cup having the same. The suction cup includes a suction cup body including a connection part at an external side thereof, and a suction surface at an internal side thereof. The suction cup body includes a soft rubber layer and a hard rubber layer. The soft and hard rubber layers together form the suction surface of the suction cup body. The soft rubber layer has hardness less than that of the hard rubber layer. In a sucking state, the hard rubber layer can provide favorable supporting strength, and the soft rubber layer readily deforms by a suction pressure to fill a supporting surface, facilitating to seal the supporting surface tightly. The soft and hard rubber layers enhance a suction capacity of the suction cup body on an uneven surface, expanding a scope of an application of the vacuum suction cup.

Abstract: A base component for loading, hanging or supporting objects has a connecting rod connected with a fixed base and a cover which sleeves the connecting rod and covers the fixed base. The fixed base is connected with the connecting rod by a linear guide pair. The linear guide pair is closed for avoiding digression after the fixed base is covered by the cover. The base component is simple in structure and convenient to install and use, because it allows changing loaded objects rapidly without disassembling the fixed base.

Abstract: A suction cup includes a main body made of flexible material and having a disk shape, and a supporting and connecting assembly connected to the main body and made of hard material. A side wall of the supporting and connecting assembly is provided with external threads, an edge of the main body is provided with a first suction structure, a side of a longitudinal section of the first suction structure is of a stepped shape having at least three levels of steps, and a top of the first suction structure is higher than a center area of a top of the main body. A suction cup device includes the suction cup, a tightening cap and a switching knob.

Abstract: A suction disk structure including: a soft rubber suction disk (1) with a draw bar (11), a base (2) provided on a back face of the soft rubber suction disk (1) and a return spring (3) located between the soft rubber suction disk (1) and the base (2). Two sides of an end of the draw bar (11) is provided with a pin shaft (12) radially extended, and the suction disk further includes a driving device (4) for driving the draw bar (11) to rise and fall. The driving device (4) comprises a pushing switch (41) mounted on the base (2) and a driving slide cover (5) connected with the pushing switch.
