Electrode protection cover of dry battery

The utility model provides a dry battery electrode protection cover which is a plastic cover body coaxially covering the positive electrode end of a dry battery, the center position of the end face of the positive electrode end of the dry battery protrudes outwards to form a positive electrode terminal, and external threads are arranged on the peripheral wall of the positive electrode terminal. And an internal thread matched with the external thread is arranged on the inner circumferential wall of the plastic cover body. The dry battery electrode protection cover disclosed by the utility model is fixedly connected with the positive terminal of the dry battery in a threaded fit manner, so that the electrode protection cover is effectively prevented from falling off. 本实用新型提供一种干电池电极保护盖，其为一同轴盖设在干电池的正极端的塑胶盖体，所述干电池的正极端端面中心位置向外凸起形成正极端子，所述正极端子的外周壁上设有外螺纹，所述塑胶盖体的内周壁上设有与所述外螺纹相互配合的内螺纹。本实用新型的所述干电池电极保护盖通过螺纹配合的方式与所述干电池的正极端子螺纹固定连接，有效避免电极保护盖脱落。
