As shown in fig. 1, the utility model discloses an alkaline battery negative pole frame, it includes packing ring 1 and diaphragm 2, and packing ring 1 and diaphragm 2 are encapsulated by battery case 3, and the space between packing ring 1 and the diaphragm 2 constitutes enclosure space 4, and the negative pole 5 is packed in the enclosure space 4, and encapsulates anodal 6 between diaphragm 2 and the battery case 3. A negative terminal plate 7 is arranged on the outer side of the gasket 1, the negative terminal plate 7 is connected with the negative electrode 5 through a current collector 8, and a space between the negative terminal plate 7 and the gasket 1 forms an exhaust buffer zone 9. The top of the gasket 1 is also provided with a slot 15 matched with the edge of the negative terminal plate 7, the edge of the negative terminal plate 7 is inserted into the slot 15 and then is pressed tightly under the action of the battery shell 3, and the fixation of the negative terminal plate 7 is completed.
In the utility model discloses in, as shown in fig. 1 and 2, be equipped with at least one exhaust hole 10 that link up from top to bottom on packing ring 1 for through exhaust hole 10 intercommunication between exhaust buffer 9 and enclosure space 4, be equipped with sealing plug 11 in exhaust hole 10 simultaneously, sealing plug 11 sliding connection is in exhaust hole 10. When the internal pressure of the battery is increased, the pressure of the closed space 4 is greater than that of the vent buffer area 9, and the sealing plug 11 moves under the pressure of the closed space 4 to communicate the closed space 4 with the vent buffer area 9, so that pressure balance is achieved. Further, a spring 12 may be connected between the sealing plug 11 and the negative terminal plate 7, and when the internal pressure of the battery is reduced, the sealing plug 11 seals the exhaust hole 10 again by the spring 12 to prevent leakage.
