The utility model discloses a battery cap convenient to coat
mucilage glue, and relates to the related technical field of batteries. The cap comprises a cap body, a limiting
assembly, an elastic ring and a fixing disc, the limiting
assembly is fixed to the inner bottom of the cap body and comprises a flexible
lantern ring, the elastic ring is fixed to the inner wall of the flexible
lantern ring, the fixing disc is movably connected to the upper portion of the inner wall of the elastic ring, and the flexible ring is fixed to the edge of the bottom end of the fixing disc. And an elastic rubber sleeve is fixed at the bottom end of the flexible ring. Through the arrangement of the cap main body, the limiting
assembly, the elastic ring and the fixed disc, the problems that when the battery cap works, glue is not convenient to align with a gluing position during gluing, gas generated during working of a battery is directly exhausted, and potential safety hazards are easily generated are solved; the battery cap has the advantages that when the battery cap works, the
adhesive is more conveniently applied to the
adhesive application position, the steel shell can be prevented from being deformed when the battery works, gas cannot be leaked, and the battery cap is
safer to use.
