Abrégé

The high-negative-pressure composite hard suction cup has a main member made of a hard, composite material tightly joined to a highly flexible washer made of soft plastic along a bottom side. The main member is configured with a vacuuming mechanism to another side. The vacuuming mechanism includes a piston chamber, one-way valve, piston assembly, and spring. A vacuum alarming assembly is configured on the piston assembly. When a degree of vacuum between the hard suction cup and an object attached is less than satisfactory, an audio or visual alarm is issued and an alert marking is revealed to notify a user to take appropriate action so that the hard suction cup remains reliably attached to the object.

Abrégé

Disclosed is a high-negative-pressure composite hard suction cup. A suction cup main body is made of a hard material, and one face of the hard suction cup main body (1) and a high-elasticity flexible rubber gasket (2) are composited into a whole and are not easily separated. A vacuumizing mechanism composed of a piston cylinder barrel (4), a one-way valve (6), a piston assembly and a spring (7) is arranged on the other face of the hard suction cup main body (1). The piston assembly on the vacuumizing mechanism is provided with a vacuum degree early-warning assembly. The pressure intensity of the hard suction cup on a suctioned object can be increased by means of high negative pressure, deformation of the high-elasticity flexible rubber gasket (2) on the hard suction cup is larger under the high pressure intensity, the sealing effect and the frictional force between the hard suction cup and the suctioned object can be effectively increased, the suction cup can suction onto a smooth or non-smooth airtight planar object, and the bearing force is increased. When a vacuum degree cannot meet a pre-set requirement in a suction process, a sound alarm or a light alarm will be given immediately, an early-warning colour code (12) will also be exposed, and the vacuum degree can be increased after immediate treatment, ensuring that the suction cup will not fall off.
