Abstract

The utility model relates to the technical field of a sealing product, in particular to a sealing structure which is not afraid of being punctured repeatedly. The technical scheme which the sealing structure adopts is as follows: the sealing structure comprises a container used for containing fluid, a sealing piece used for sealing a port of the container is arranged on the container, the sealingpiece comprises a plastic body and a flexible sealing body, and the flexible sealing body is sealed in the plastic body. When in use, as the flexible sealing body in the sealing piece exerts the key function, the sealing structure can still keep sealed when the sealing piece is repeatedly punctured by a syringe needle. The plastic body at the outer layer in the sealing piece exerts the function offixing and can make sure the position of the entire sealing piece is fixed. When the syringe needle moves, due to being made of materials with certain ductility and fluidity, the flexible sealing body in the middle can timely make up for gaps generated by the moving of the syringe needle so as to ensure the sealing property of the entire sealing piece.

Description

A kind of hermetically-sealed construction

Technical field:

The utility model relates to the sealed product technical field, refers in particular to a kind of hermetically-sealed construction that is repeatedly punctured of not fearing.

Background technology:

Traditional hermetically-sealed construction is to reveal for gas, the liquid placed in container or the space, for example the products such as tightening seal washer that use in the piping facility.But in the daily life, we need some sealed product to take out at any time, but the taking-up process, and after taking out, wish that container, space still keep sealing.The container that for example is used for the carrying liquid medicine, it adopts the rubber bottle cap to clog vessel port usually.So promptly can play sealing effectiveness, can also make things convenient for syringe needle to insert simultaneously.During use, syringe needle (or other Injection heads) can be inserted the rubber bottle cap, the soup in the container is taken out.After obtaining the dosage that needs, syringe needle is extracted.Because the material behavior of rubber bottle cap, its through hole that is pierced can driving fit when syringe needle is extracted, so just places in the air admission container in the external world, prevents liquid medicine contamination.

But also there is certain shortcoming in this hermetically-sealed construction: the rubber bottle cap can bear the syringe needle puncture of some, but owing to can't guarantee that each position of puncturing is in same point, if puncture time is too much, syringe needle more or less can produce wound to rubber bodies, cause rubber bodies to restore, stay the slit, seal failure.

The utility model content:

Problem to be solved in the utility model just is to overcome the shortcoming of present product, and a kind of hermetically-sealed construction that is punctured of not fearing is provided.The puncture time that the sealing structure can be born substantially exceeds present product.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: the sealing structure comprises the container in order to the splendid attire fluid, this container is provided with the sealing member that is used to seal its port, and the sealing part comprises plastic body and the flexible sealing body that is sealed in the plastic body.

Described sealing member adopts stacked mechanism, and flexible sealing body is packaged in the confined space of two plastic bodies formation.

Described plastic body is the bloated skin that rubber is made.

Described container is a body, is provided with described sealing member in the container two-port.

Principle of work of the present utility model is: when syringe needle repeatedly during puncture seal spare, the utility model still can keep sealing, and this is because flexible sealing body plays a key effect in the sealing member.Be positioned at outer field plastic body in the sealing member and play fixation, guarantee whole sealing member stationkeeping, and middle flexible sealing body has certain ductility, the material of flowing power, when syringe needle moves, it can in time remedy the slit of moving generation because of syringe needle, guarantees the leak tightness of whole sealing member.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is the structural representation of the utility model embodiment two.

The specific embodiment:

See Fig. 1, present embodiment comprises container 1, and a sealing member 2 is installed on the port of container 1, by sealing part 2 with port sealing.Sealing part 2 comprises plastic body 21 and the flexible sealing body 22 that is sealed in the plastic body 21.

As shown in the figure, described sealing member 2 adopts stacked mechanism, and flexible sealing body 22 is packaged in the confined space of two plastic bodies, 21 formations.Usually, plastic body 21 adopts the bloated skin of rubber making.

When using present embodiment, the syringe needle 31 of syringe 3 pierces through whole sealing member 2, injecting fluid or extraction liquid in container, in whole piercing process, because the existence of plastic body 21 and flexible sealing body 22, can not form the gap between syringe needle 31 and the sealing member, so extraneous air can not enter in the container 1, liquid can not leak yet in the container 1.When syringe needle 31 was extracted, the through hole that sealing member 2 is pierced can driving fit when syringe needle 31 is extracted, so just placed in the extraneous air admission container or internal liquid is revealed.

When syringe needle time puncture seal spare more than 31 2, the utility model still can keep sealing, and this is because flexible sealing body 22 plays a key effect in the sealing member 2.Be positioned at outer field plastic body 21 in the sealing member 2 and play fixation, guarantee whole sealing member 2 stationkeeping, and middle flexible sealing body 22 has certain ductility, the material of flowing power, when syringe needle 31 moves, it can in time remedy the slit of moving generation because of syringe needle 31, guarantees the leak tightness of whole sealing member 2.

See Fig. 2, this is another embodiment of the present utility model, and present embodiment is used for the paint color mixing machine.Container 1 is a body in the present embodiment, is provided with described sealing member 2 in container 1 two-port, and container 1 also is communicated with an oil return pipe 6.One oil inlet 4 is communicated with needle body 5, and needle body 5 can move up and down, thereby drive syringe needle 51 inserts in the containers 1 or passes completely through container 1.

When this product uses,,, guarantee to paint and can not reveal so adopt the utility model can guarantee the leak tightness of entire container 1 because syringe needle 51 need constantly move up and down.

During use, paint is by being extruded behind oil inlet 4, the needle body 5, because the needle tubing bore on the needle body 5 is very little, can well control the outflow capacity, and the paint by needle tubing drippage drips the drops that tool is standard, can accurately calculate the flow of paint, thereby makes the paint flow output can accuracy control.When paint need be to extraneous oil spout, needle body 5 moved down under the external world drives, and this moment, the syringe needle 51 of needle body 5 passed completely through leak free container 1, promptly passed the sealing member 2 at container 1 two ends simultaneously, and the paint beginning is flowed out by syringe needle 51.When not in use, needle body 5 moves up under the external world drives, and this moment, syringe needle 51 outlets were retracted in the container 1, continue oil spout order paint this moment and will be full of entire container 1, and more than paint will be back to by oil return pipe 6 and form a circulation in the paint container.Because syringe needle 51 is by in the paint solution of infiltration in container 1, so the paint in the syringe needle 51 can not solidify, when treating that use next time, it is descending to promote needle body 5, and oil spout gets final product again.

Flexible sealing body 22 in the utility model can adopt silica gel, and silica gel has certain ductility, flowing power, can play good sealing effectiveness.

The embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all do variation or modification according to the described shape of the utility model claim, structure, feature and spiritual principle all should be included in the utility model claim.
