Description
Technical Field
The utility model relates to a battery seal structure, in particular to sealing washer of P type battery.
Background
The zinc chloride type zinc-manganese battery sealing ring is arranged at the battery sealing position and between the battery shell and the positive current collector. Because of its decisive effect on the leakage resistance of the battery, there are high demands on the structural form of the sealing ring. With the development of battery technology, higher requirements are put on battery performance, and how to increase the effective volume inside the battery to increase the filling amount of active materials in the battery is a necessary means for improving the battery performance. The key point for increasing the filling amount of active substances in the battery is to reduce the effective volume occupied by the sealing ring in the battery. Therefore, the sealing ring affects not only the liquid leakage resistance of the battery but also the overall performance of the battery. The commonly used sealing ring of the P-type battery is a structure with the same physical size of all new materials of low-density polyethylene, needs to occupy larger volume in the battery, limits the increase of the filling amount of active substances, and is not suitable for the requirement of the technical development of the battery.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model aims to provide a novel sealing washer of P type battery of simple structure, sealed effectual, thickness is little.
In order to achieve the purpose, the P-type battery sealing ring of the utility model is integrally made of an inner annular sealing ring and an outer annular sealing ring which are coaxially arranged and a horizontal sealing ring which is horizontally connected between the inner sealing ring and the outer sealing ring, and the longitudinal sections of the two sealing rings are two H shapes after being made; the diameter of the outer sealing ring is equivalent to the diameter of the inner surface of a battery zinc cylinder, and the height of the inner sealing ring and the height of the outer sealing ring are 2.7-2.9 mm; an annular protrusion is provided on an outer circumferential surface of the outer seal ring.
Further, the annular bulge is arranged at the upper end of the outer circumference of the outer sealing ring.
Further, the height of the annular bulge is 0.8-0.9 mm.
Further, the height of the inner sealing ring is 2.6, and the height of the outer sealing ring is 2.8 mm; the upper ends of the inner seal and the outer seal are positioned on the same horizontal plane.
The thickness of the battery sealing ring with the structure is reduced by one third, so that the manufacturing cost is reduced, the effective volume of the sealing ring in the battery is reduced, the increase of the filling amount of active substances in the battery is facilitated, and the discharge capacity is improved; the physical size of the lower part of the excircle of the sealing ring is consistent with the size of the opening of the zinc cylinder, the physical size of the upper part of the excircle of the sealing ring is increased by 0.8-0.9mm, the sealing ring is in closer contact with the inner wall of the zinc cylinder, and the sealing performance and the liquid leakage resistance of the battery are improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 3 and 4, the P-type battery sealing ring of the present invention is integrally formed by an inner 1 and an outer 2 coaxially disposed annular sealing rings and a horizontal sealing ring 3 horizontally connected between the inner and outer two sealing rings, and has two H-shaped longitudinal sections after being formed; the diameter of the outer sealing ring is equal to the diameter of the inner surface of the battery zinc cylinder, and the heights of the two sealing rings are 2.7-2.9 mm; an annular projection 4 is provided on the outer circumferential surface of the outer seal ring.
The annular bulge can be arranged at any position of the outer circumference surface according to the requirement, but the annular bulge is preferably arranged at the upper end of the outer circumference of the outer sealing ring for the convenience of installation because the whole height of the sealing ring is small. Similarly, the height of the annular projection is 0.8-0.9mm for easy installation.
Further, the height of the inner sealing ring is 2.6, and the height of the outer sealing ring is 2.8 mm; the upper ends of the inner seal and the outer seal are positioned on the same horizontal plane. Therefore, the installation is facilitated, and the sealing performance can be improved.
In order to facilitate the coating of the sealant during sealing, the lower ends of the inner sealing ring and the outer sealing ring are provided with guide angles, so that the mounting is facilitated, and a large amount of sealant can be accommodated to enhance the sealing effect.
In conclusion, the thickness of the battery sealing ring with the structure is reduced by one third, so that the manufacturing cost is reduced, the effective volume of the sealing ring in the battery is reduced, the increase of the filling amount of active substances in the battery is facilitated, and the discharge capacity is improved; the physical size of the lower part of the excircle of the sealing ring is consistent with the size of the opening of the zinc cylinder, the physical size of the upper part of the excircle of the sealing ring is increased by 0.8-0.9mm, the sealing ring is in closer contact with the inner wall of the zinc cylinder, and the sealing performance and the liquid leakage resistance of the battery are improved.
