Abstract
The utility model discloses a kind of battery seal rings of liquid-leakage preventing, it includes sealing ring body, extend a circle limiting stand in the back side of the sealing ring body, it is isolated tube nozzle accommodating cavity inside the limiting stand, the diameter of the opening portion of the limiting stand is slightly larger than the caliber of isolated tube, and the internal diameter of the bottom of limiting stand is adapted with the caliber of isolated tube.The utility model is installed on the nozzle nesting of isolated tube in limiting stand by the limiting stand extended in sealing ring body, limiting stand defines the movement of isolated tube, isolated tube shaking overflows calamine cream when avoiding battery by sharp pounding, thus battery is avoided the phenomenon that internal short-circuit occur.
Description
Technical field
The utility model relates to alkaline battery manufacturing field more particularly to a kind of battery seal rings of liquid-leakage preventing.
Background technique
In general, alkaline battery includes cathode, anode, diaphragm and electrolyte.Its processing technology is added inside battery steel shell
Enter positive and negative pole material and isolated tube, the open end of battery steel shell is then sealed with the sealing ring of insulation, and the side of steel shell is rolled up
It is pressed above sealing ring, so that entire steel shell is closely tamping.
Currently, the sealing ring that alkaline battery uses on the market, (i.e. with the binding face of the isolated tube containing negative electrode active material
The back side of sealing ring) be a relatively flat face, battery occur intense impact vibration when, the surface cannot play restriction every
Effect from pipe, the calamine cream in isolated tube are easy to overflow in sharp pounding, the manganese dioxide contact of the calamine cream and anode of spilling,
It will lead to internal short-circuit of battery, generate the security risks such as hot phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of battery seal rings of liquid-leakage preventing.
Realizing the technical solution of the utility model aim is: a kind of battery seal ring of liquid-leakage preventing comprising sealing ring sheet
A circle limiting stand is extended at body, the back side of the sealing ring body, is isolated tube nozzle accommodating cavity inside the limiting stand, described
The diameter of the opening portion of limiting stand is slightly larger than the caliber of isolated tube, and the internal diameter of the bottom of limiting stand is mutually fitted with the caliber of isolated tube
Match.
Further, the depth of the limiting stand is 1.0mm~2.5mm.If the depth of limiting stand is too deep, it can account for and tie up too
The loading of the active matter of battery is reduced, and then influences the discharge performance of battery in more steel shell spaces.
The utility model makes the nozzle nesting of isolated tube be installed on limit by the limiting stand extended in sealing ring body
In platform, limiting stand limits the movement of isolated tube, and isolated tube shaking overflows calamine cream when avoiding battery by sharp pounding, thus
Battery is avoided the phenomenon that internal short-circuit occur.
Detailed description of the invention
Fig. 1 is the vertical profile structural schematic diagram of sealing ring body described in the utility model embodiment 1；
Fig. 2 is sealing ring body described in the utility model embodiment and isolated tube mounting structure schematic diagram.
Specific embodiment
It elaborates below in conjunction with attached drawing to the utility model preferred embodiment.
As depicted in figs. 1 and 2, a kind of battery seal ring of liquid-leakage preventing comprising sealing ring body 1, the sealing ring sheet
Extend a circle limiting stand 12 on the back side 11 of body 1, is isolated tube nozzle accommodating cavity, the limiting stand inside the limiting stand 12
The internal diameter A of 12 opening portion 121 is slightly larger than the caliber of isolated tube 10, internal diameter B and the isolated tube 10 of the bottom 122 of limiting stand 12
Caliber is adapted；The depth of the limiting stand is 1.0mm~2.5mm.
When installation, directly 101 nesting of nozzle of isolated tube 10 is installed in limiting stand 12, limiting stand 12 limits isolation
The movement of pipe, isolated tube shaking overflows calamine cream when avoiding battery by sharp pounding, thus battery is avoided internal short-circuit occur
The phenomenon that.
The depth of limiting stand described in the utility model is not limited to described in embodiment, if but limiting stand depth it is too deep, can account for
Too many steel shell space is tied up, reduces the loading of the active matter of battery, and then influence the discharge performance of battery；Limiting stand depth
It is too shallow, then it is unfavorable for limiting the nozzle of isolated tube.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent process transformation made by the utility model description, it is applied directly or indirectly in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
Claims (2)
1. a kind of battery seal ring of liquid-leakage preventing comprising sealing ring body, it is characterised in that: the back side of the sealing ring body
Extend a circle limiting stand, be isolated tube nozzle accommodating cavity inside the limiting stand, the internal diameter of the opening portion of the limiting stand omits
Greater than the caliber of isolated tube, the internal diameter of the bottom of limiting stand is adapted with the caliber of isolated tube.
2. the battery seal ring of liquid-leakage preventing according to claim 1, it is characterised in that: the depth of the limiting stand is
1.0mm~2.5mm.
