So that connector connect with cover.
Preferably, the sealing ring circular cone shape that is in, upper end diameter are big, the upper end trepanning communicates shape with circular cavity
Into lasso, lasso is sleeved on pressing plate so that sealing ring is connect with laminate.
Preferably, the lantern ring ring-type of the connector is more than 180 °, connection column diameter, straight less than stopper is had a diameter larger than
Diameter；The outer connecting portion in lantern ring both sides, its be equipped with the circular arc that connect with groove, the maximum distance of circular arc is more than the spiral shell of cover
Pit diameter is less than groove diameter.
Preferably, the connector is the product that stainless steel wire curves.
Preferably, further include the elastic component between stopper and cover.
Preferably, the elastic component is the rubber pad for the tapped blind hole bottom end for being located at cover.
Preferably, being equipped with protrusion among the elastic component, lug boss is contradicted with stopper.
Preferably, the elastic component is the spring for being located at cover or stopper upper end.
Compared with the prior art, the utility model has the advantage of：
1st, the utility model connects cover with sealing-plug so that sealing-plug is easily drawn out, even if container by connector
Internal pressure is smaller, without by tamper tool.And sealing-plug plug dress is convenient, is directly tightened in company with cover and is crushed on appearance
Device bottleneck；Cover is connected with sealing-plug so that sealing-plug is not easy to lose, can be preferably used cooperatively.
2nd, the utility model, cover and sealing-plug, which connect, not to be increased the processing cost of cover and sealing-plug, does not change
Existing cover and sealing-plug obtain manufacturing process, and connector adds single practical easy to process, at low cost, good connecting effect.
3rd, the utility model sets elastic component between cover and stopper, avoids the rigid contact of cover and stopper, together
When laminate is caused to have persistently appropriate downward pressure so that sealing is plugged with preferable leakproofness, increase sealing-plug use the longevity
Life.

Specific embodiment
With reference to the accompanying drawings of the specification and specific embodiment, utility model is described in detail.
Embodiment
As shown in figs. 1-7, a kind of sealing cover, including cover 1, sealing-plug and the connector of connection cover and sealing ring
3, cover 1 is equipped with internal thread for cylindrical, lower ending opening, and the 1 internal thread upper end of cover is equipped with toroidal cavity 11, sealing-plug
Including the sealing ring 22 that laminate 21 and 21 lower end of laminate are arranged, certain sealing-plug can also be integrally formed.The laminate 21
Lower end is the pressing plate 211 prominent to circumference, and pressing plate 211 is equipped with connecting pole 212, and connecting pole 212 is equipped with the stopper of protrusion
213, certain connecting pole 212 can be cylinder, Polygonal column shape etc..22 upper end opening of sealing ring, opening and circular cavity phase
Logical to form lasso 221, lasso 221 is socketed on pressing plate 211, and 22 tapered lower end diameter of sealing ring is smaller compared with upper end diameter.Institute
It states connector 3 and is equipped with lantern ring 31 of the opening less than 180 ° to be intermediate, outwardly extending outer connecting portion 32 is connected on the outside of annulus, this
In embodiment, lantern ring 31 is small compared with the diameter of connecting pole 21 for the spacing at circular open both ends, and the diameter of lantern ring 31 is compared with stopper 213
Small, lantern ring 31 is connected on cylindrical connecting pole 212 and is connect with laminate 21.Outer link portions 32 are located in groove 11 and connection cover
Body 1 connects.
In the present embodiment, as shown in fig. 6, connector 3 is the annulus of symmetric design that stainless steel wire curves, certainly, connection
Part 3 can also be rectangle ring-type, can be also made of iron plate etc., connector 3 is formed with sealing-plug and cover 1 removably to be connected
It connects, it is simple in structure, it is at low cost.
It is out-of-date using, sealing ring 3 is socketed on pressing plate 211 and forms sealing-plug, the lantern ring 31 and sealing-plug of connector 3
Connecting pole 212 connect, outer link portions 32 are connect with cover 1 so that sealing-plug and cover 1 are formed detachably by connector 3
Flexible connection.When tightening, 1 end cap of cover is withstood in stopper 213, sealing ring 21 is made closely to connect with bottleneck the force of laminate 21
It connects；When taking out cover 1, since connector 3 is acted on so that cover 1 connects, while sealing-plug is taken out with sealing-plug.
When used for a long time, sealing ring 21 will appear aging and abrasion, and when cover 1 and laminate 21 are rigid contact, it is close
Blocking is susceptible to the phenomenon that sealing is not tight.For this purpose, elastic component 4 is equipped between cover 1 and stopper 213.The elastic component 4
It can be rubber pad 41 of the pad in 1 tapped blind hole bottom end of cover, certainly, be set among ground rubber parts with 213 contact site of stopper
Prominent Elastic Contact position；The elastic component 4 or spring 42,42 one end of spring can be viscous with stopper 213 or cover 1
Knot can also set groove to place spring 42 in stopper 213 or cover 1.
