Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
Realization of the present utility model is described in detail below in conjunction with specific embodiment.
Referring to figs. 1 to shown in 3, for the utility model provides preferred embodiment.
The battery cap that the utility model is provided can be used in lithium battery, it is also possible to be used in other batteries, and
One of which is not limited only to, fluid-filling structure is the important component in battery cap.
The fluid-filling structure of battery cap includes cover plate 100 and closing cock 101, and wherein cover plate 100 is arranged in the form of sheets, its use
Liquid injection hole is provided with the upper end open for being sealed on housing, cover plate 100, the liquid injection hole runs through the upper end and lower end of cover plate 100,
Through hole is namely formed, so, when battery cap is sealed on the upper end open of housing, battery fluid then can be by liquid injection hole
It is directly injected into enclosure interior；Closing cock 101 is then directly filled in liquid injection hole, so, then can realize the closing to liquid injection hole.
In the present embodiment, liquid injection hole includes upper segment and lower section 103, wherein, upper segment is formed in lower section 103
Top, and along direction from bottom to top, the side wall of upper segment in skewed arrangement outwardly, then directly fill out by above-mentioned closing cock 101
Fill in the upper segment of liquid injection hole, and then whole liquid injection hole is realized to close.
