Preferably, the arc surface bulge loop is two or more, formed between every two arc surface bulge loop for filling
The groove of sealant.
Preferably, it is described it is several circle arc surface bulge loop between groove it is of same size.
Compared with prior art, the utility model has the beneficial effects that:
The utility model includes sealing ring body, is offered in the sealing ring body logical for placing cylindrical battery cap
Hole, the sealing ring body are sheathed on cylindrical battery cap surface, lateral surface and/or the medial surface setting of the sealing ring body
There are several circle arc surface bulge loops, the arc surface bulge loop is elastomer, when arc surface bulge loop is a circle, the arc surface bulge loop
It can be formed with battery case mutual extrusion and seal defence line together, enhance leakproofness, to effectively avoid the electricity in cylindrical battery
Solution liquid leakage simultaneously avoid negative cover bottom from separating with sealing ring, when arc surface bulge loop for two enclose it is above when, arc surface bulge loop it
Between the groove that is formed sealant can be filled, improve sealing effect.Its structure is simple, is readily produced preparation.

Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The embodiments of the present invention provide a kind of cylindrical battery sealing ring for effectivelying prevent electrolyte to ooze out.
Embodiment one
Referring to FIG. 3, the utility model provides a kind of cylindrical battery sealing ring for effectivelying prevent electrolyte to ooze out, including circle
Bar shape sealing ring body 1 offers the through-hole 2 for placing cylindrical battery, the sealing ring sheet in the sealing ring body 1
Body 1 is sheathed on the surface of cylindrical battery, and the lateral surface of the sealing ring body 1 is provided with several circle arc surface bulge loops 11, described
Arc surface bulge loop 11 is elastomer, and structure is simple, is readily produced preparation.
In the present embodiment, on 1 outer wall of sealing ring body, sealing ring is immersed in by one circle arc surface bulge loop 11 of design
In sealant, can there be sealant in outside in sealing ring, take out sealing ring later and toast 3h at 60 DEG C, be dried, to close
After sealant in seal is dried, use can be assembled.In other embodiments, the sealing ring body 1 and arc surface
Bulge loop 11 can also be sealant.The arc surface bulge loop 11 can form with battery case mutual extrusion and seal defence line together,
Enhance leakproofness, so that the solution leakage in cylindrical battery is effectively avoided, since the shape of arc surface bulge loop 11 is circular arc
