Zinc-manganese dry battery without sealing adhesive

Abstract

The invention discloses a zinc-manganese dry battery without a sealing adhesive. The device comprises a zinc cylinder and a positive cap; the top of the zinc cylinder is fixedly connected with a positive electrode cap; sealing plastic is mounted below the positive electrode cap; the sealing plastic is of an annular structure; a first sealing mechanism is mounted on the outer wall of the sealing plastic; a positioning mechanism is mounted at the bottom of the sealing plastic; a second sealing mechanism is mounted on the inner side of the sealing plastic; and a supporting mechanism is disposed below the positioning mechanism. According to the invention, a dry battery is sealed through the first sealing mechanism and the second sealing mechanism on the sealing plastic, the good sealing effectis achieved, no toxic gas is generated in the sealing process, the sealing opening is supported through the supporting mechanism, and extrusion deformation of the dry battery is prevented.

Description

technical field [0001] The invention relates to the technical field of dry batteries, in particular to a zinc-manganese dry battery without sealing glue. Background technique [0002] Dry batteries belong to primary batteries in chemical power sources and are disposable batteries. Because the electrolyte of this chemical power supply device is a paste that cannot flow, it is called a dry battery, which is relative to a battery with a flowable electrolyte. Dry batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also suitable for various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine. [0003] Ordinary dry batteries are mostly manganese-zinc batteries, with a positive carbon rod in the middle, a mixture of graphite and manganese dioxide on the outside, and a layer of fiber mesh on the outside. The mesh is coated w...

Problems solved by technology

[0007] The purpose of the present invention is to provide a zinc-manganese dry battery without sealing glue, to solve the problem that most of the existing zinc-manganese dry batteries in the above-mentioned background technology are sealed with sealing glue, because the sealing glue will volatilize toxic The gas will affect the health of the working personnel; the structural strength of the sealing part of the existing zinc-manganese dry battery is not high, and the zinc-manganese dry battery is easily deformed by extrusion, which will affect the sealing effect
