Abstract
The invention relates to a vacuumized small part vacuum cap, in particular to a small part vacuum cap which can be matched with a vacuum pump to pump air out of sealed hollow metal products, hollow plastic products and hollow rubber products to form a certain vacuum degree. According to the technical solution, a product similar to an expansion bolt is formed and manufactured from plastic in an injection molding mode, the front end of the product is an elastic pointed end with the retraction and expansion functions, the rear end of the product is a detachable screw cap with threads on the two faces, and the middle of the product is provided with a vent hole, a sealing ring, a sealing plug, a spring and an air pumping duct. When the vacuum cap is used, a hole smaller than the elastic pointed end is drilled in a container first, the vacuum cap is inserted in the container, the screw cap is screwed down according to the thickness of the container, then, an air pipe on the vacuum pump is screwed on the screw cap to pump air, after all the air in the container is pumped, the air pipe is screwed off, and the whole process is completed.
Description
Technical field
A kind of finding vacuum cap vacuumizing, particularly relate to and coordinate vacuum pump can from the metal hollow goods that sealed, plastic hollow goods, hollow rubber goods, extract gas wherein out, thereby make them form the to a certain degree finding vacuum cap of vacuum.
Background technique
People need to extract gas wherein out from the hollow body of sealing under many circumstances, not oxidized in the hope of the material in protection container.The metal floating debris for example using in water need to be extracted air wherein out to extend the life-span of floating debris and to increase buoyancy.And for example the long-term preservation of food and chemical product all needs to extract out the air in seal container so that preserve for a long time.Some storage things can constantly produce gas, so need to repeatedly vacuumize.Need to have one to vacuumize easily part for this reason and meet these demands.
Solving at present the way of extracting gas wherein from the hollow body of sealing out, is, on the hollow body of sealing, one-way valve is installed, and exhausts after the gas in container, and one-way valve is still retained on container.Existing one-way valve volume is large, installation process complexity, completely practical requirement.
Summary of the invention
Order of the present invention is to overcome the deficiencies in the prior art part, and a kind of succinct, practical, the vacuum cap that convenient, cost of production is low is provided.This finding vacuum cap vacuumizing, can coordinate vacuum pump from the metal hollow goods that sealed, plastic hollow goods, hollow rubber goods, to extract gas wherein out, thereby make them form the to a certain degree finding vacuum cap of vacuum, it is characterized in that finding vacuum cap front end is the elasticity tip with convergent-divergent function, rear end is that two sides has the demountable nut of screw thread, and middle part is vent, seal ring, sealing plug, spring, the groove of bleeding.Technical solution of the present invention is: make the product of a similar EXPANSION ANCHOR BOLTS of injection molding, front end is made into the elasticity tip with convergent-divergent function, and rear end is made into two sides the demountable nut of screw thread, middle part makes vent, seal ring, sealing plug, spring, the groove of bleeding.First on the container vacuumizing at needs when use, bore one and be less than elasticity tip hole, the present invention is inserted in container, screw nut of the present invention according to the thickness of container, then the tracheae of vacuum pump is spun on nut of the present invention and is bled, exhaust in container after gas, screw off tracheae and just complete.Technical characteristics of the present invention is, the tip that uses the vacuum cap of plastic production to have convergent-divergent function coordinates with nut can pass container easily, and the close-coupled of maintenance and container, can only see a nut body in container outside, the little container appearances that do not affect of volume, be convenient to repeatedly extract the gas in container out, after bleeding, internal tank is that vacuum negative pressure condition makes good sealing effect be difficult for leaking.
The invention has the beneficial effects as follows, the container vacuumizing for needs provide a kind of simple, convenient, and reliable, can widely used finding vacuum cap.
