Under sealing state, described sealing and installing hole are sealed and matched, and described the first silica gel ring and the second silica gel ring closely cooperate; Under ventilative state, described sealing is positioned at installing hole top, and described ventilation part is positioned at installing hole and communicates with installing hole top.
Preferably, described installing hole be shaped as cylindrical hole, described sealing and ventilation part are all cylinder, and the outer wall of ventilation part is provided with the air discharge duct that downward-extension arranges.
Preferably, described dynamic seal also comprises limiting section, described limiting section be relative ventilation part bottom radial level stretch out arrange circulus, the diameter of section of described limiting section is greater than the diameter of installing hole, and described air discharge duct up/down perforation limiting section.
Preferably, the diameter of section of described ventilation part is less than the diameter of section of sealing.
Preferably, described pulling part is provided with arc cell body away from the upper surface of sealing.
Preferably, the upper surface of described the first silica gel ring is provided with helical groove, and the lower surface of described the second silica gel ring is provided with the spiral salient with helical groove corresponding matching.
Preferably, described helical groove direction of rotation is from inside to outside counterclockwise or clockwise.
The beneficial effects of the utility model: because dynamic seal comprises pulling part, sealing, ventilation part and limiting section, can make whole dynamic seal up and down in installing hole by pulling part knee-action, and then realize sealing and the airing function of seal cover, product structure is simple, easy to operate, durable. Can ensure that by limiting section and pulling part whole dynamic seal can not depart from installing hole in up and down process, easy to carry. Again because lower surface, pulling part is provided with the second silica gel ring, lid main body upper surface is provided with the first silica gel ring arranging with installing hole coaxial communication, make under sealing state, sealing and installing hole are sealed and matched, the first silica gel ring and the second silica gel ring closely cooperate, greatly strengthen between installing hole and sealing and pulling part and lid main body between sealing property, ensure seal cover air tight under sealing state, Stability Analysis of Structures.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-3, the present embodiment provides a kind of airtight lid for container, comprises and covers main body 10, sealing ring 20 and dynamic seal 30.
In the present embodiment, described sealing ring 20 fixed covers are located on all sides of covering main body 10, described sealing ring 20 is by the first ring portion, the second ring portion and the 3rd ring portion composition, described the first ring portion is horizontally disposed with and inner wall surface thereof is provided with the mounting groove for the described lid main body 10 of pegging graft, described the second ring portion vertically arranges and is connected with the bottom inner peripheral one of the first ring portion, described the 3rd ring portion connects and the radially outward horizontal-extending setting of relative the second ring portion with the bottom one of the second ring portion, described in this, the 3rd ring portion contributes to strengthen the sealing property between seal cover and container inner wall face, preferably described the 3rd ring portion is made up of polypropylene material.
Described lid main body 10 is provided with the installing hole 11 of up/down perforation, described installing hole 11 be shaped as cylindrical hole. The upper surface of described lid main body 10 is also fixedly installed the first silica gel ring 40, and described the first silica gel ring 40 is coaxial with installing hole 11 and be communicated with setting.
