Abstract
Plug is blocked the utility model discloses a kind of lithium ion battery with aluminum shell liquid injection hole, for blocking the liquid injection hole on cover plate, including handle and installed in the stopper rod of handle, at its lower end, the diameter of the handle is more than the diameter of stopper rod, the stopper rod bottom is provided with external screw thread, the externally threaded path, the diameter of stopper rod are consistent with the internal diameter of liquid injection hole, and the externally threaded pitch is more than the thickness of cover plate.This plug includes handle and stopper rod, stopper rod can effectively prevent the immersion of outside batteries moisture and impurity, handle is that human hand crawl is used, convenient working personnel capture plug and plug plug operation, and stopper rod head has screw thread, can avoid because battery producing gas internal pressure is excessive and caused by plug loosen or wash open, in addition, the plug is easy to operate, it is not necessary to clean cull, reusable.
Description
Technical field
The utility model is related to technical field of lithium ion, more particularly to a kind of repeatable aluminum hull lithium-ion electric utilized
Pond liquid injection hole closure plug.
Background technology
The cover plate of lithium ion battery with aluminum shell has a 1.3 ~ 1.5mm of φ liquid injection hole, in battery manufacturing process, liquid injection hole
It is main to make electrolyte injection and Battery formation exhaust is used, after Battery formation and exhaust are finished, with it is more slightly larger than fluid injection aperture not
Rust steel steel ball blocks liquid injection hole, inside battery active component is completely cut off with housing environment.
Because battery needs the gas produced in chemical conversion, formation process, it is necessary to be drained before steel ball is played, therefore, battery exists
Liquid injection hole can not be blocked after fluid injection with steel ball at once；In order to prevent the external water impurity that grades from entering inside battery, in battery liquid-filling
, will note after battery liquid-filling before being blocked afterwards to liquid injection hole by steel ball during this section, it is desirable to have a kind of removable plug
Fluid apertures is blocked, and before battery is vented and beaten steel ball operation, can be removed the plug.
The removable plug used at present, which is generally after gummed paper, battery liquid-filling, is touched liquid injection hole using gummed paper, by
There is electrolyte residual in liquid injection hole, gummed paper, which exists, pastes not tight hidden danger, it is necessary to which gummed paper is tightened with rubber band, is vented and beats before steel ball
Need rubber band to be untied and wiped off gummed paper, beat after steel ball and again scrub gummed paper residue, using very inconvenient, during waste
Between.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of repeatable aluminum hull lithium ion utilized
Battery liquid-filling hole blocks plug.
The utility model solve technical scheme that its technical problem used for：
A kind of lithium ion battery with aluminum shell liquid injection hole blocks plug, for blocking the liquid injection hole on cover plate, including handle and peace
Mounted in the stopper rod of handle, at its lower end, the diameter of the handle is more than the diameter of stopper rod, and the stopper rod bottom is provided with external screw thread, described
Externally threaded path, the diameter of stopper rod are consistent with the internal diameter of liquid injection hole, and the externally threaded pitch is more than the thickness of cover plate.
As the improvement of above-mentioned technical proposal, the stopper rod is additionally provided with contraposition part, the contraposition part positioned at external screw thread lower end
For inverted cone or inverted round stage.
As the improvement of above-mentioned technical proposal, the handle and stopper rod are coaxially disposed.
As the improvement of above-mentioned technical proposal, the periphery of the handle is used for anti-skidding salient point provided with some.
As the improvement of above-mentioned technical proposal, the handle and stopper rod are by PP plastics and rubber mix injection molding.
The beneficial effects of the utility model have：
This plug includes handle and stopper rod, and stopper rod can effectively prevent the immersion of outside batteries moisture and impurity, and handle is
Human hand crawl is used, convenient working personnel crawl plug and plug plug operation, and stopper rod head has screw thread, can avoid because of electricity
Pond aerogenesis internal pressure is excessive and causes plug to loosen or wash open, in addition, the plug is easy to operate, it is not necessary to clean cull, repeats
Use.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Referring to Fig. 1, a kind of lithium ion battery with aluminum shell liquid injection hole closure plug of the present utility model, for blocking cover plate
Liquid injection hole, including handle 1 and the stopper rod 2 installed in the lower end of handle 1, the diameter of the handle 1 is more than the diameter of stopper rod 2, institute
State handle 1 and stopper rod 2 is coaxially disposed, the periphery of the handle 1 is used for anti-skidding salient point, convenient working personnel crawl provided with some
Plug and plug plug operation, the handle and stopper rod are by PP plastics and rubber mix injection molding, and dimensional accuracy is high, there is bullet
Property, for blocking liquid injection hole, it can effectively prevent the immersion of outside batteries moisture and impurity.
For further increase steadiness, the bottom of stopper rod 2 is provided with external screw thread 3, path, the stopper rod 2 of the external screw thread 3
Diameter it is consistent with the internal diameter of liquid injection hole, the pitch of the external screw thread 3 is more than the thickness of cover plate, facilitates external screw thread 3 and cover plate
Coordinate, stopper rod 2 is screwed in liquid injection hole.
In addition, the stopper rod 2 also has contraposition part 4 positioned at the lower end of external screw thread 3, the contraposition part 4 is inverted cone or inverted round stage,
In the present embodiment, contraposition part 4 is inverted cone, and contraposition is played when inserting liquid injection hole.
It is described above, simply better embodiment of the present utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches technique effect of the present utility model with any same or similar means, should all belong to of the present utility model
Protection domain.
