And fixing structure is used for mounting cylindrical lithium battery into lead-acid shell

The utility model discloses a fixing structure for installing a cylindrical lithium battery into a lead-acid shell. The fixing structure comprises a shell and a battery bracket, wherein the shell comprises an upper top cover and a lower shell which are oppositely buckled; a plurality of groups of fixedly connected battery brackets are arranged in the lower shell; the size of the battery bracket ismatched with the internal space of the lower shell; a copper bar is arranged on the contact end face of the battery support and the lower shell. According to the fixing structure, the cylindrical lithium battery is fixed in the lead-acid shell without changing the appearance and the size of the lead-acid shell, and the internal fixing structure is not fixed by screws, so that the operability is improved during installation, and the convenience and the operability of replacing the lead-acid battery with the lithium battery during operation are facilitated. 本实用新型公开了一种将圆柱锂电池装入铅酸壳体内的固定结构，包括壳体和电池支架；壳体包括相对扣合的上顶盖和下壳体；下壳体内设置
