Embodiment only in order to explain the utility model, is not used to limit the utility model.
As shown in figure 1, being a preferred embodiment of battery cap in the utility model, this battery cap includes
Block body 1, is provided with cavity, cavity upper end is provided with top through hole 2, lower end is provided with bottom in block body 1
Through hole 3, is additionally provided with top shoe 4, sliding block 5, hollow pipe 6, inner spring 8 and Tensile in cavity
Outer spring 12.Top shoe 4 is located at the top of sliding block 5, and hollow pipe 6 is located in top shoe 4 and sliding block
In 5, it is slidably disposed in top shoe 4, and is fixedly connected with sliding block 5.Hollow pipe 6 bottom
It is fixedly connected with sealing ball 7, sealing ball 7 is located on the downside of the bottom through-hole 3 of cavity, has a diameter larger than cavity
Bottom through-hole 3 diameter, hollow pipe 6 bottom and sealing ball 7 between be provided with opening 9.Inner spring 8
Between top shoe 4 and sliding block 5, outer spring 12 two ends are connected with cavity top, sliding block 5 respectively.
The utility model also provides a kind of battery, including battery body (not shown), on battery body
It is provided with above-mentioned battery cap.
After above-mentioned battery roller slot seal, it is possible to achieve initiative exhaust.Only top shoe 4 need to be pressed, make cunning
Block 4 is contacted with sliding block 5, drives sliding block 4 to bottom offset, because hollow pipe 6 is fixing with sliding block 5
Together, thus hollow pipe 6 is also to bottom offset so that sealing ball 7 is also to bottom offset, preliminary filling is aging, circulation
During the gas that produces can discharge from opening 9, ensure that the internal pressure of battery after exclusion gas stably；
Fluid infusion can also be carried out from hollow pipe 6 after exhaust, secondary injection can be carried out after circulating battery certain time
Liquid, makes up electrolyte consumption it is ensured that electrolyte is sufficient, gives the secondary life of battery, and overall improves electricity
Pond service life.
Specifically, block body 1 center is in that protruding column shape is arranged, and cavity is located at block body 1 center,
Cavity is cylindrical.Top shoe 4 and sliding block 5 are cylindrical, and top shoe 4 top is connected to the top of cavity
In portion's through hole 2, top shoe 4 bottom and sliding block 5 top annular are provided with the dentalation matching.Glide
Block 5 slipper seal sets in the cavities it is ensured that the air of battery bottom can only be discharged from hollow pipe 6, prevents
In the cavities, top shoe 4 downside center and sliding block 5 upper center are respectively equipped with spring base 13 to accumulated gases,
Inner spring 8 two ends are located in spring base 13 it is ensured that the fixation of inner spring 8, extend use time, inner spring
8 are in compressive state, and in no external force state, top shoe 4 is pushed up top by inner spring 8, and opening 9 is
Arc port, sealing ball 7 fixation is located at arc port two ends, and it is in arc that arc port design makes bottom through-hole 3 inwall
Shape is arranged, and matches with sealing ball 7 surface, when sealing ball 7 is in bottom through-hole 3, by bottom through-hole
3 seal up.As shown in figure 3, annular is alternately provided with high-order draw-in groove 10 and low level draw-in groove 11 on cavity inner wall,
High-order draw-in groove 10 and low level draw-in groove 11 directly process on cavity inner wall it is ensured that draw-in groove to meet positioning strong
Degree requires, and is provided with corresponding fixture block 14 outside sliding block 5.
In not exhaust condition at ordinary times, as shown in figure 1, hollow pipe 6 upper end and top shoe 4 upper end are same
Plane, under inner spring 8 effect, top shoe 4 is separated with sliding block 5, and top shoe 4 sealing is placed in cavity
Top through hole 2 in, seal inner chamber, sliding block 5 simultaneously outer spring 12 effect under, its fixture block 14 sets
In high-order draw-in groove 10, because hollow pipe 6 is fixing with sliding block 5, sealing ball 7 is again fixing with hollow pipe 6,
Now sealing ball 7, under hollow pipe 6 drive, is in close contact with the bottom through-hole 3 of cavity, prevents electrolyte
Leakage.
Under exhaust or fluid injection state, as shown in Fig. 2 when pressing top shoe 4 and contacting with sliding block 5, under
Slide block 5 departs from high-order draw-in groove 10 to bottom offset, then fixture block 14, and in the presence of dentalation, fixture block
14 rotate to low level draw-in groove 11, so that hollow pipe 6 and sealing ball 7 is moved down, sealing ball 7 departs from sky simultaneously
At the bottom through-hole 3 in chamber, opening 9 connects with inside battery, realizes exhaust and fluid injection.During fluid injection, only need
Inject electrolyte from hollow pipe 6 top, after exhaust and fluid injection finish, then press top shoe 4,
Sliding block 5 guides high-order draw-in groove 10 by low level draw-in groove 11, and sealing ball 7 seals the bottom through-hole 3 of cavity again.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,
