the utility model provides a waterproof lithium battery shell, includes the last casing, lower casing and the lithium cell who comprises last casing and lower casing hold the chamber, still including the seal gasket that is used for sealed waterproof, be equipped with spacing recess down on the casing, seal gasket locates in the spacing recess, go up be equipped with on the casing with the chimb of corresponding and butt of spacing recess, go up the casing warp the chimb butt in be equipped with seal gasket in the spacing recess and fixed connection in casing down.
Furthermore, the convex edge, the sealing gasket and the limiting groove are provided with corresponding connecting through holes in a distributed manner.
Furthermore, the upper shell, the lower shell and the sealing gasket are fixedly connected through screws respectively penetrating through the connecting through holes.
Further, the sealing gasket is a silica gel gasket.
Further, the thickness of the sealing gasket is 1-2 mm.
Furthermore, reinforcing ribs which are uniformly distributed are respectively arranged at the inner bottoms of the upper shell and the lower shell.
Furthermore, a handle groove and a handle piece are further arranged on the upper shell.
Furthermore, the handle piece is fixedly arranged on the upper shell and positioned above the handle groove.
To sum up, the utility model has the advantages that: it sets up seal gasket through the spacing recess on the casing down to going up the chimb butt on the casing in rather than the corresponding spacing recess of casing down, and passing the chimb respectively through the screw rod, corresponding connect the via hole is fixed on seal gasket and the spacing recess, and it is simple structure not only, convenient operation, and the leakproofness is good, effectively avoids the condition of leaking of screw hole, does not have the potential safety hazard, and be fit for mass production, also can glue the cooperation with beating simultaneously and use.
