The utility model discloses an alkaline zinc-manganese dioxide battery, including steel casing, conductive graphite, positive polar ring, barrier paper, negative pole calamine cream, battery seal body etc. wherein, the sealing washer that seals the body is the nylon seal circle, is equipped with the centre bore in the middle of this nylon seal circle, and the periphery is equipped with cyclic annular explosion-proof ditch, and the current collector passes the centre bore of nylon seal circle, and forms interference fit with the nylon seal circle, and this radial equipartition of nylon seal circle is equipped with strengthening rib or the radial thickness increase of this nylon seal circle to increase the radial strength of nylon seal circle, cancel original supplementary gasket. The nylon sealing ring with the structure is processed by a certain method, the central hole can form interference fit with a collector (copper needle), the central column is effectively prevented from being broken, the necessity of using a sealing cap is eliminated, and the assembly production process of the collector is simplified. Meanwhile, the axial length of the nylon sealing ring is reduced, the effective volume in the battery is increased, the filling amount of active substances is increased, and the battery capacity is increased.
Description
Technical Field
The utility model relates to an alkaline zinc-manganese dioxide battery, in particular to an alkaline zinc-manganese dioxide battery with improved sealing body sealing ring performance.
Background
In the conventional zinc-manganese battery, a PP (polypropylene is a main component) material is used as a battery sealing body, and in order to prevent leakage of the battery, a sealing cap (as shown in fig. 1) which is used for increasing strength and preventing loose matching needs to be installed on the periphery of a central column in a sealing diagram, but due to the poor high-temperature resistance and aging resistance of the PP material, the use locality of the PP material is obviously limited. Currently, various large battery companies have started to use nylon as a material of a sealing ring of a sealing body, and in order to increase the strength of the nylon sealing ring, various factories often adopt a method of adding an auxiliary gasket (as shown in fig. 2). This not only complicates the current collector assembly production process, but also increases the production cost of the battery.
Disclosure of Invention
An object of the utility model is to provide a new construction nylon seal circle without auxiliary pad replaces present widely used nylon seal circle to simplify and seal body assembly process, reduce the cost, improve the alkaline zinc-manganese dioxide battery of battery performance.
In order to realize the above object, the utility model relates to an alkaline zinc-manganese dioxide battery, including steel casing, conductive graphite, positive polar ring, barrier paper, negative pole calamine cream, battery seal body etc. wherein, the sealing washer of the body of the seal is the nylon seal circle, is equipped with the centre bore in the middle of this nylon seal circle, and the periphery is equipped with annular explosion-proof ditch, and the current collector passes the centre bore of nylon seal circle, and forms interference fit with the nylon seal circle, and this radial equipartition of nylon seal circle is equipped with strengthening rib or this radial thickness of nylon seal circle and increases to increase nylon seal circle radial strength, cancel original auxiliary pad piece.
The nylon sealing ring with the structure is processed by a certain method, the central hole can form interference fit with a collector (copper needle), the central column is effectively prevented from being broken, the necessity of using a sealing cap is eliminated, and the assembly production process of the collector is simplified. Meanwhile, the axial length of the nylon sealing ring is reduced, the effective volume in the battery is increased, the filling amount of active substances is increased, and the battery capacity is increased.

The present invention will be further described in detail with reference to the accompanying drawings.
Fig. 1 is a partial sectional view of a sealing ring of a sealing body made of PP material for a conventional battery.
Fig. 2 is a partial sectional view of a conventional nylon gasket and an auxiliary gasket of a battery.
Fig. 3 is a cross-sectional view of the overall structure of the battery of the present invention.
Fig. 4 is a top view of the nylon seal ring (8 reinforcing ribs) of the present invention.
Detailed Description
Referring to fig. 3 and 4, an alkaline zinc-manganese dioxide battery 1 includes a steel casing, conductive graphite, a positive ring, isolation paper, a negative zinc paste, a battery sealing body 12, etc., wherein a center hole 13 is formed in the middle of a nylon sealing ring of the sealing body 12, an annular anti-waterfall groove 14 is formed around the nylon sealing ring, a current collector 11 passes through the center hole 13 of the nylon sealing ring 12 and forms an interference fit with the nylon sealing ring 12, and the nylon sealing ring 12 is uniformly and radially provided with more than 2 reinforcing ribs 15, typically 8 reinforcing ribs. This nylon seal ring 12's axial length can suitably reduce to increase the inside effective volume of battery, improve active material's packing volume, increase battery capacity, increase simultaneously and establish behind the strengthening rib 15, greatly increased nylon seal ring 12's radial strength, can cancel original auxiliary pad piece in actual production process, simplified the current collector equipment production technology, reduced the manufacturing cost of battery.
The utility model discloses also can adopt the radial thickness who increases nylon seal 12 to increase its radial strength.
