DETAILED DESCRIPTION

[0024] A square single-cell battery box, see Figure 1-Figure 4 , which includes a shell 10, an inner tank 20, a battery cover 30, and a pressure relief safety valve 40;

[0025] The housing 10 is formed by a front plate 11, a left side plate 12, a rear plate 13, and a right side plate 14, and the space formed by the enclosure is a square inner container placement cavity 15;

[0026] The inner tank 20 includes a battery placement cavity 50 and a cover plate placement cavity 60. The battery placement cavity 50 is surrounded by a bottom plate 51, a front plate 52, a left plate 53, a rear plate 54, and a right plate 55. The cover plate placement cavity 60 is formed by a bottom connection frame 61 and surrounding panels 62.

[0027] The battery cover 30 includes a cover body 31, a positive electrode column 32, and a negative electrode column 33. The positive electrode column 32 and the negative electrode column 33 are fixed on the cover body 31. The positive electrode column 32 and the negative electrode column 33 are directly arranged on the cover body 31 through injection molding after processing. The cover body 31 is also provided with a valve hole 34 at a position corresponding to the positive electrode column 32 and the negative electrode column 33.

[0028] The inner liner 20 is tightly fitted and inserted into the inner liner placement cavity 15 from top to bottom, and the cover plate placement cavity 60 is protruded from the upper end of the outer shell 10. The battery cover 30 is tightly fitted and plugged into the cover plate placement cavity 60 from top to bottom. The lower mounting end of the pressure relief safety valve 40 is tightly inserted into the valve hole 34, and the upper part of the pressure relief safety valve 40 is exposed from the valve hole 34.
