Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of alkaline batteries, and more specifically, to a negative terminal cover of an alkaline battery. Background Art
[0002] An alkaline battery is an electrochemical cell in which the electrolyte between the positive and negative electrodes is alkaline. This type of battery usually uses potassium hydroxide or sodium hydroxide as the electrolyte, zinc or nickel as the negative electrode, and oxygen or silver oxide as the positive electrode. Alkaline batteries usually have a relatively high energy density and a long service life. Common alkaline battery types include carbon-zinc batteries, alkaline manganese batteries, and nickel-metal hydride batteries. Alkaline batteries are widely used in many household electronic devices and industrial applications.
[0003] In electrical appliances that are used periodically, alkaline batteries are usually still left in the appliances when they are not in use. Alkaline batteries will produce a slight discharge phenomenon. After a long time, when they are used again, the alkaline batteries will often be out of power and need to be re-prepared.
[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model aims to provide a negative terminal cover for an alkaline battery.
[0006] The above technical purpose of the utility model is achieved through the following technical scheme: the negative terminal cover of the alkaline battery includes a sheet body, a rotating column is fixedly connected to the center of the sheet body, an insulating sheet 1 is rotatably connected to the rotating column, a recess for accommodating the insulating sheet 1 is opened on the sheet body, an insulating sheet 2 is fixedly connected in the recess, and the cross-sections of the insulating sheet 1 and the insulating sheet 2 are the same and both are half the area of the sheet body.
[0007] The utility model is further configured as follows: a pointed portion is fixedly connected to the insulating sheet.
[0008] The utility model is further configured as follows: a rotating part is fixedly connected to the insulating sheet, and a rotating hole is opened on the rotating part and is passed through by the rotating column.
[0009] The utility model is further configured as follows: a sliding cavity is provided on the rotating column, a sliding column is slidably connected in the sliding cavity, and a blocking portion is fixedly connected to one end of the sliding column away from the sheet body.
[0010] The utility model is further configured as follows: one end of the sliding column facing away from the blocking portion is fixedly connected to the limiting portion, and the plane cross-sectional area of the limiting portion is larger than the area of the opening of the sliding cavity.
[0011] The utility model is further configured as follows: a compression spring is arranged in the sliding cavity, and the compression spring is located at a side of the limiting part facing the blocking part.
[0012] The utility model is further configured as follows: a groove is provided on the sheet body.
[0013] The utility model is further configured as follows: the sheet body is made of aluminum alloy material.
[0014] In summary, the utility model has the following beneficial effects:
[0015] By arranging a rotating column on the sheet body, when the insulating sheet 1 rotating on the rotating column rotates to the concave part of the sheet body, the sheet body contacts the negative pole of the battery, so that the battery can be used normally and energized. When the insulating sheet 1 rotates 180° along the rotating column, the insulating sheet 1 can isolate the sheet body from the battery. At the same time, the insulating sheet 2 located in the concave part can also prevent the concave part of the sheet body from contacting the battery, thereby achieving a circuit-breaking effect.

DETAILED DESCRIPTION
[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Negative terminal cap for alkaline batteries, such as Figures 1 to 4As shown, it includes a sheet body 1, a rotating column 2 is welded at the center of the sheet body 1, so that the insulating sheet 3 can rotate along the center of the sheet body 1, and the rotating column 2 is rotatably connected with the insulating sheet 3, and the insulating sheet 3 is bonded to the negative electrode of the battery by glue. The sheet body 1 is provided with a recess 4 for accommodating the insulating sheet 3. When the insulating sheet 3 is located in the recess 4 of the sheet body 1, the sheet body 1 is in conflict with the negative electrode of the battery, so that the battery can be normally used and energized, and an insulating sheet 2 5 is bonded in the recess 4 by glue, and the cross-sections of the insulating sheet 3 and the insulating sheet 2 5 are the same and are both on the surface of the sheet body 1. When the insulating sheet 1 3 rotates 180° along the rotating column 2, the insulating sheet 1 3 and the insulating sheet 2 5 are in a non-overlapping state. At this time, the insulating sheet 1 3 enters between the sheet body 1 and the battery, so that the insulating sheet 1 3 can isolate the sheet body 1 from the battery. At the same time, the insulating sheet 2 5 located in the recess 4 can also prevent the recess 4 of the sheet body 1 from contacting the battery, thereby achieving a circuit-breaking effect. The sheet body 1 is made of aluminum alloy material, so that the sheet body 1 has good strength. The insulating sheet 1 3 and the insulating sheet 2 5 are both made of polyurethane material, which has good insulation and heat resistance.
[0023] like Figures 1 to 4 As shown, a pointed portion 6 is integrally formed on the insulating sheet 3, so that when the insulating sheet 3 enters between the sheet body 1 and the battery, the pointed portion 6 can spread the sheet body 1 and the battery apart, a rotating portion 7 is integrally formed on the insulating sheet 3, and a rotating hole 8 is provided on the rotating portion 7 for the rotating column 2 to pass through, so that the insulating sheet 3 can rotate on the rotating column 2, and a sliding cavity 9 is provided on the rotating column 2, and a sliding column 10 is slidably connected in the sliding cavity 9, and a blocking portion 11 is fixedly connected to the end of the sliding column 10 away from the sheet body 1, and the blocking portion 11 can limit the rotating portion 7, so that the insulating sheet 3 is kept rotating on the rotating column 2, when the insulating sheet 3 rotates out of the recess 4, the sliding column 10 slides in the sliding cavity 9, and the blocking portion 11 gradually moves away from the rotating column 2, so that the sheet body 1 is separated from the battery, and a limiting portion 12 is integrally formed on the end of the sliding column 10 facing away from the blocking portion 11, and the plane cross-sectional area of the limiting portion 12 is larger than the sliding cavity 9. The area of the opening of the moving cavity 9 is such that the sliding column 10 keeps rotating in the sliding cavity 9, and the cross-section of the limiting portion 12 is circular, so that the sliding column 10 can slide in the sliding cavity 9. A compression spring 13 is provided in the sliding cavity 9, and the compression spring 13 is located on the side of the limiting portion 12 facing the blocking portion 11, so that when the insulating sheet 3 returns to the groove 14, the compression spring 13 restores its elastic deformation and provides a force on the limiting portion 12. At this time, the limiting portion 12 slides toward the bottom of the sliding cavity 9, and the blocking portion 11 gradually approaches the rotating column 2, so that the sheet 1 can fit with the negative electrode of the battery to achieve the power-on effect. A groove 14 is provided on the sheet 1, so that the operator can buckle the fingernail of the finger into the groove 14, which is convenient for rotating the sheet 1. Since the insulating sheet 3 and the negative electrode of the battery are bonded by glue, when the sheet 1 rotates, the insulating sheet 3 and the sheet 1 rotate relative to each other.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
