Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a lithium cell with antidetonation anti-rupture structure, the lower cover 5 that sets firmly including lower sleeve 4 and lower sleeve 4 below, lower cover 5 top is provided with upper cover 1, upper cover 1 lower extreme has set firmly and is honeycombed array's last sleeve 3, lower sleeve 4 top cover is equipped with

opening arris shell

6, 3 bottom opening part of upper sleeve and 6 top end opening part sliding connection of opening arris shell, 6 inner chamber butts of opening arris shell have battery package 7, terminal surface butt under 7 tops of battery package and the upper cover 1, it has screw rod 2 to run through the grafting between upper cover 1 and the lower cover 5, set up the third step groove 502 of pegging graft with the cooperation of 2 inflation head departments of screw rod on the lower cover 5, first step groove 101 has been seted up on the upper cover 1, first step groove 101 endotheca is equipped with screw rod 2 and closes nut 201 of being connected soon, make screw rod 2 and nut 201 close mutually and carry out fixed mounting with upper cover 1 and lower cover 5.
