Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings:
The lithium ion battery of the repeatable seal of improvement as shown in Figure 1, the lithium ion of the repeatable seal of a kind of improvement
Battery, including battery case 1, cover plate 2, black box 20, described battery case 1 has an electrolyte chamber 3, has electrolysis in electrolyte chamber 3
Liquid, described cover plate 2 is fixed on described battery case 1, and described cover plate 2 has a taper liquid injection hole 4, described taper liquid injection hole 4
Big end is near described electrolyte chamber 3, and described taper liquid injection hole 4 inwall is provided with the annular positioning groove 14 of a level；Described sealing group
Part 20 includes gripper shoe 12, spring 6, seals cone 5, and described gripper shoe 12 is provided with more than one perforation 13, described gripper shoe 12
Snapping in described annular positioning groove 14 makes described gripper shoe 12 be horizontally fixed in described taper liquid injection hole 4, and the described cone 5 that seals is arranged
In described taper liquid injection hole 4, seal cone 5 and be preferably made up of elastoplast, so can improve sealing effectiveness.Described sealing is bored
5 ends greatly are held corresponding to the big of described taper liquid injection hole 4, and described sealing cone 5 minimum diameters are minimum more than described taper liquid injection hole 4 directly
Footpath, it is identical with described taper liquid injection hole 4 inner wall shape that 5 lateral surface shapes are bored in described sealing, and one end of described spring 6 is connected to institute
Stating in gripper shoe 12, the other end of described spring 6 withstands on described sealing on cone 5 bottom faces；Set on described taper liquid injection hole 4 inwall
The cannelure 11 being positioned at the level above described annular positioning groove 14, described sealing is had to bore the cylindrical hole that level is set in 5
7, described through hole 7 is positioned at above described cannelure 11, in described through hole 7 described sealing when cone 5 seals described taper liquid injection hole 4
Arranging cylindrical push rod 10, the lateral diameters of described push rod 10 is less than described through hole 7 bore dia, and described sealing is bored 5 top end faces and set
Putting the spacing hole 8 that communicate vertical with described through hole 7, arrange cylindrical push rod 9 in described spacing hole 8, the side of described push rod 9 is straight
Footpath is less than described spacing hole 8 pore radius, and described push rod 9 one end protrudes from outside described spacing hole 8, is positioned at described spacing hole 8
Described push rod 9 other end is vertically connected on described push rod 10 one end near described through hole 7 center, presses down described push rod 9 water
Putting down and push out described push rod 9, the described push rod 10 extended through hole of the other end 7 is outer and enters in cannelure 11.So without
When injecting electrolyte, 6, spring seals cone 5 and upwards pushes up, and more than taper liquid injection hole 4 small end and seals cone 5 owing to sealing cone 5 small ends
Side view is identical with taper liquid injection hole 4 shape, makes sealing cone 5 tightly withstand near taper liquid injection hole 4 small end, through hole 7 simultaneously
It is positioned at above cannelure 11, thus realizes sealing.When needs are toward injection electrolyte in electrolyte chamber 3, means of press seals cone the most down
5, push out push rod 9 simultaneously and make push rod 10 enter in cannelure 11, unclamp hands, seal cone 5 under the effect of spring 6, drive push rod
10 are moved upward to cannelure 11 top, and now push rod 10 sealing cone 5 is fixed in taper liquid injection hole 4, the most just can be along cone
Electrolyte is injected, due to the lateral diameters of push rod 9 in taper liquid injection hole 4 in shape liquid injection hole 4 inwall and the space sealed between cone 5
Less than the lateral diameters of described spacing hole 8 pore radius and push rod 10 less than described through hole 7 bore dia, it is possible to from spacing hole 8 through logical
Electrolyte is injected in taper liquid injection hole 4 in hole 7, and the electrolyte perforated 13 flowed in taper liquid injection hole 4 flows in electrolyte chamber 3；
After having noted electrolyte, push rod 9 makes push rod 10 leave cannelure 11 the most inward, seals cone 5 the closeest under the effect of spring 6
Seal taper liquid injection hole 4.
In the lithium ion battery of the repeatable seal of described improvement, the most described spacing hole 8 axis and described sealing
Boring 5 deads in line, described through hole 7 axis seals cone 5 axes intersect with described；The most described push rod 10 has two and lays respectively at
Described through hole 7 both sides, described push rod 9 has two and connects two described push rods 10 respectively.Push rod 9 so can be facilitated to operate,
And make sealing cone 5 be in horizontal equilibrium position all the time, thus advantageously in the injection of electrolyte.
The above is only embodiment of the present utility model and the introduction of technological means used, and is not new to practicality
The restriction of type, disclosing and illustrating that any change made, equivalence replacement, improvement etc. are accordingly to be regarded as being included in this practicality according to this paper
Within novel technology category.
