Abstract

A bearing sucker is a tool sucked to a wall plane or other planar objects. The bearing sucker is characterized in that a solid hemispheroid (1) is cast through metal or engineering plastic, a bearing point (2) of tension and gravity is located at the top end of the hemispheroid (1), an annular groove is formed in the outer edge of the plane of the hemispheroid (1), and protruding annular elastic rubber sealing rings (3) are embedded in the annular groove; an end surface thread groove is formed in the plane of the hemispheroid (1), protruding elastic rubber cushion strips (4) are embedded in the end surface thread groove, and an air hole (5) connected with an air pumping mechanism is formed in the portion, between two of the cushion strips, of the hemispheroid (1). The bearing sucker can bear a large tension or a large gravity or a large pressure.

Description

Load-bearing sucker

Technical field:

The utility model relates to a kind of sucker, particularly a kind of sucker that bears gravity.

Background technique:

When the sucker using is at present negative pressure in sucker, suction is all very strong, can bear larger pulling force.But when on sucker top again when weight application or pressure, sucker is difficult to bear, sucker top can depression, causes suction to decline, and even there is no suction, and lose absorption, is stabilized in the effect in body of wall or plane object.

Model utility content:

Technical problem to be solved in the utility model is: provide a kind of on being adsorbed on body of wall or plane object time, it not only can bear larger pulling force, but also can bear the load-bearing sucker that larger gravity or pressure can not be flattened.

Technical solution adopted in the utility model is: with metal or engineering plastics, be cast as solid hemisphere, hemispheroidal top is bearing a little of pulling force and gravity, there is toroidal cavity at the place, outer of hemisphere plane, studs with protruding ring elastic gel seal ring in toroidal cavity; In hemisphere plane, there is end-face helical groove, in end-face helical groove, stud with protruding elastic gel filler strip, on the hemisphere between filler strip and filler strip, have the pore linking with extraction sector.

Adopt after above structure, the utility model load-bearing sucker compared with prior art has following advantage: 1, because the hemisphere of this sucker is that solid metal or engineering plastics are cast as, so can bear larger gravity or pressure; 2, because there is seal ring hemisphere plane outer, inside there is end-face helical shape colloid filler strip, so, can very equably gravity or pressure be passed to body of wall or other plane object of being inhaled, and frictional force is large; 3, because seal ring and end-face helical shape filler strip are protruding hemisphere planes, so hemisphere plane does not directly contact body of wall or other plane object, between seal ring and end-face helical shape filler strip, form negotiable air passageways, while being convenient to need absorption, bleed, air inlet while not needing to adsorb; 4, seal ring is universal standard part, good seal performance, and price is low, easily implements.

Accompanying drawing explanation:

Accompanying drawing is the utility model load-bearing sucker sectional structure schematic diagram.

In accompanying drawing: 1, solid hemisphere; 2, hard point; 3, toroidal cavity and seal ring; 4, end-face helical connected in star and end-face helical shape filler strip; 5, pore.

Embodiment:

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

On the utility model load-bearing sucker, there is solid hemisphere 1, hard point 2, toroidal cavity and seal ring 3, end-face helical connected in star and end-face helical shape filler strip 4, pore 5.During use, this sucker is attached in wall plane or other plane object, rotating three-way valve makes pore connect vacuum source, air in circular seal ring is drawn out of by pore 5, make formation vacuum in seal ring, this hemisphere 1 is attracted in body of wall or other plane, and hard point 2 not only can bear larger pulling force; But also can bear larger gravity or pressure, and can not be flattened, because area of contact is large, frictional force is large, and can not slide; When needs take off while removing this sucker, rotate three-way valve air is entered in seal ring by pore, make inside and outside air pressure balance, this sucker has not just had suction, just can very like a cork this sucker be taken off and removed.

The utility model load-bearing sucker, it not only can bear larger pulling force, but also can bear larger gravity or pressure.

Claims

1. load-bearing sucker, it is a kind of utensil being adsorbed in wall plane or other plane object, it is characterized in that: with metal or engineering plastics, be cast as solid hemisphere (1), the top of hemisphere (1) be pulling force and gravity bear point (2), the place, outer of hemisphere (1) plane has and in toroidal cavity, toroidal cavity, studs with protruding ring elastic gel seal ring (3); In hemisphere (1) plane, there is end-face helical groove, in end-face helical groove, stud with protruding elastic gel filler strip (4), on the hemisphere (1) between filler strip and filler strip, have the pore (5) being connected with extraction sector.
