The beneficial effects of the utility model: owing to dynamic seal is by pulling part, sealing, ventilation part and limit
Position portion form, by pulling part knee-action can make whole dynamic seal in installing hole up and down,
And then realizing sealing sealing and the airing function of lid, product structure is simple, easy to operate, durable.Logical
Cross limiting section and pulling part can ensure whole dynamic seal during up and down without departing from installing hole,
Easy to carry.Again owing to being socketed with silica gel ring outside sealing, it is connected between limiting section with lid main body lower surface and has
Compression spring, in sealed states sealing and silica gel ring together with installing hole interference fit, compression spring
Axial length be less than its drift, by the pressuring action of silica gel ring, compression spring to down spring effect
And the position-limiting action of pulling part makes sealing connection in sealed states and between installing hole the most firm steady
Fixed, the sealing property being greatly enhanced between installing hole and sealing, it is ensured that seal lid and do not leak
Gas, Stability Analysis of Structures, the close gas free air space being sealed under ventilative state can be made bigger, it is simple to beat simultaneously
Open sealing lid.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As Figure 1-3, the present embodiment provides a kind of fresh-keeping sealing cover, including lid main body 10, sealing ring 20
And dynamic seal 30.
In the present embodiment, described sealing ring 20 fixed cover is located on all sides of lid main body 10, described close
Seal 20 is made up of the first ring portion, the second ring portion and the 3rd ring portion, and described first ring portion is horizontally disposed with and in it
Wall is provided with for the mounting groove of lid main body 10 described in grafting, and described second ring portion is vertically arranged and with first
The bottom inner peripheral one of ring portion connects, and described 3rd ring portion connects and relative with the bottom of the second ring portion one
The second the most horizontal-extending setting of ring portion, this described 3rd ring portion contributes to strengthening sealing to be covered and crisper
Sealing property between internal face, the most described 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 cylinder
Hole.
Described dynamic seal 30 is made up of pulling part 31, sealing 32, ventilation part 33 and limiting section 34.
Described pulling part 31 is fixedly connected on the top of sealing 32, and described limiting section 34 is fixedly connected on ventilation part
The lower section of 33, described sealing 32 and ventilation part about 33 connect and are coaxially disposed.
In the present embodiment, the rounded laminated structure in described pulling part 31, described pulling part 31 is away from sealing
The upper surface in portion 32 is provided with arc cell body, is so easy to lift described pulling part 31, meets human engineering.
In the present embodiment, described sealing 32 and ventilation part 33 all in cylinder, described ventilation part 33
Diameter of section is less than the diameter of section of sealing 32, and described limiting section 34 is relative ventilation part 33 bottom radial direction
The most extended circulus, the diameter of section of described limiting section 34 is straight more than installing hole 11
Footpath, and the outer wall of ventilation part 33 is provided with the most extended air discharge duct 330, on described air discharge duct 330
Under through limiting section 34, under ventilative state, described sealing 32 is positioned at above installing hole 11, described
Gas portion 33 is positioned at installing hole 11 and communicates above installing hole 11, so that box internal gas pressure is equal to outside box
Air pressure, is easy to open sealing lid.
In the present embodiment, described sealing 32 fixed sleeves is connected to silica gel ring 40, described limiting section 34 with
