Description
Technical field
The utility model belongs to vacuum suction device technical field, more particularly to a kind of suction that will be vacuumized in sucker
Disk air extractor.
Background technology
Existing large-scale sucker needs to extract internal gas out mainly realize by air extractor, in the market
The air extractor being evacuated for sucker is in order to which cost-effective entirety uses all-plastic material integrated formed structure, pumping dress
Putting needs to set air exhaust nozzle, and it is all the less structure of size that air exhaust nozzle, which is typically set, and the air exhaust nozzle that plastic material is made is more
Gas leakage or fracture are also easy to produce after secondary use, causes to use, thus it is low in the urgent need to developing a kind of long cost of service life
Sucker air extractor.
Utility model content
The utility model purpose be for existing sucker air extractor it is fragile and provide a kind of sucker vacuum suction
Device.
The utility model is achieved by the following technical solution：
A kind of sucker vacuum suction device, including piston cylinder and pumping piston, piston move reciprocatingly in piston cylinder
The air exhaust nozzle pumping of piston cylinder is realized, described piston cylinder is included the outer barrel being made of plastic material and uses metal material
The inner cylinder being made, inner cylinder is embedded in the inside of outer barrel, and piston does piston movement in outer barrel, and the inner cylinder includes and inner cylinder integral type
The suction nozzle of structure, suction nozzle is hollow structure, and passes through heating with the bleed-off passage that is internally formed of inner cylinder, described inner cylinder and outer barrel
Integrated structure afterwards.
Outwardly projection is provided with the outside of described inner cylinder, the cunning slided for projection is provided with the inwall of outer barrel
Groove.
The projection of chute is covered provided with stretching out on the inner cylinder directly over chute, the raised bulge size is big
In the depth of the depression of chute, the raised width is greater than the width of chute.
It is less than lower part for the section diameter that inner cylinder is inserted in outer tube inner wall upper end, and forms between top and the bottom platform
Rank mechanism, and the diameter of bore of part is less than inner cylinder overall diameter under outer barrel.
Described inner cylinder is made up of aluminum material.
The beneficial effects of the utility model：The utility model is simple in construction, and outer barrel is to be integrally formed processing letter with inner cylinder
Single quick, cost is not also high, sets metal material hardness higher inner cylinder, is hardly damaged, service life is long, with traditional plastics
Material compared to long-time use cost it is low.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model；
Fig. 2 is sectional view of the present utility model.
Embodiment
With reference to embodiment, the utility model is described in further detail.
Embodiment
A kind of sucker vacuum suction device as depicted in figs. 1 and 2, including piston cylinder and pumping piston, piston is in work
Moved reciprocatingly in plug tube and realize the air exhaust nozzle pumping of piston cylinder, described piston cylinder includes the outer barrel being made of plastic material
1 and the inner cylinder 2 that is made of metal material, inner cylinder is embedded in the inside of outer barrel, and piston does piston movement in outer barrel, and this is interior
Cylinder includes suction nozzle 21 with inner cylinder integral structure, and suction nozzle is hollow structure, and with the bleed-off passage that is internally formed of inner cylinder, it is described
Inner cylinder and outer barrel pass through integrated structure after heating.Outwardly projection 22 is provided with the outside of described inner cylinder,
The inwall of outer barrel is provided with the chute 11 slided for projection.On the inner cylinder directly over chute chute is covered provided with stretching out
Projection 23, the raised bulge size is greater than the depth of the depression of chute, and the raised width is greater than the width of chute.
Outer tube inner wall upper end is less than lower part for the section diameter that inner cylinder is inserted, and forms step mechanisms between top and the bottom, and
The diameter of bore of part is less than inner cylinder overall diameter under outer barrel.Described inner cylinder is made up of aluminum material.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, it is in the art common on the premise of the utility model spirit and scope are not departed from
Technical staff simple change and replace all be within protection domain of the present utility model.
