[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and Advantageous Effects become apparent from understanding, below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.It should be appreciated that the detailed description of the invention described in this specification is only used to explain this utility model, it is not intended to limit this utility model.
With reference to Fig. 1-Fig. 4, the utility model proposes a kind of lithium battery cap, including block matrix 1 and cylindrical cap cap head 2, described block matrix 1 includes that substrate 11 and the annular being vertically set on described substrate 11 fix post 12, there is liquid injection hole (not shown) for injecting electrolyte on described substrate 11, described annular is fixed post 12 and is enclosed and be located at outside described liquid injection hole, described cylindrical cap cap head 2 lid is located at described annular and fixes on post 12, forms described lithium battery cap with described block matrix 1.
This utility model illustrates for circle with described substrate 11, may be alternatively provided as other shapes in other embodiments.
Concrete, described cylindrical cap cap head 2 include top cover 21 and with described top cover 21 vertically disposed annular sidewall 22, the annular of described block matrix 1 is fixed the periphery of post 12 and is provided with external screw thread, it is provided with the female thread corresponding with described external screw thread inside the annular sidewall 22 of described cylindrical cap cap head 2, by external screw thread and female thread, described cylindrical cap cap head 2 is fastened on described block matrix 1.When cylindrical cap cap head 2 is separated by needs with described block matrix 1, it is only necessary to turn cylindrical cap cap head 2, so that it may make cylindrical cap cap head 2 separate with described block matrix 1.It is certainly not limited to this kind of fixed form, it is also possible to cylindrical cap cap head 2 be fixed on described block matrix 1 by other fixed forms.
So, when this block is applied in lithium battery, first block matrix 1 can be fixed on lithium battery steel shell, then carry out fluid injection by the liquid injection hole of block matrix 1, after fluid injection, more by the way cylindrical cap cap head 2 is fixed on described block matrix 1.
Further, release rubber cushion 23 can be provided with, when being located in lithium battery steel shell by the block lid in this utility model, when the pressure in lithium battery is excessive on the top cover 21 of described cylindrical cap cap head 2, pressure can be laid down by this release rubber cushion 23, in case lithium battery blast.
