The utility model has the advantages that: 1. the sealing sleeve is arranged to effectively prevent glue leakage; 2. the sealing sleeve straight hole section is in interference fit with the pole, so that the radial sealing degree of the pole is ensured; 3. the sealing ring stabilizes and seals the pole in the radial direction.
Description
Technical Field
The utility model relates to a battery production and processing technology field, specificly relate to a lid in leak protection glue battery.
Background
The function of the cover in the battery is mainly to provide through holes for passing through the poles (positive and negative poles) of the battery and to seal the poles after they have passed. At present, the sealing mode of a cover and a pole in the storage battery is mainly sealed by epoxy resin. When the sealing device is specifically implemented, the O-shaped rubber sealing ring is sleeved on the pole, the O-shaped ring is pressed into the through hole of the pole, and then the epoxy resin glue is filled in the gap between the through hole and the pole to realize sealing. The structure has the following defects that firstly, when the O-shaped ring is sleeved in the through hole of the pole, the pole needs to be corrected, otherwise, the O-shaped ring is easy to be pressed out of position, so that the sealing is not tight, the glue leaks, and the working efficiency is reduced; secondly, if the middle cover, the pole or the rubber sealing ring has flaws, impurities or uneven places, glue dispensed by the glue is easy to leak to the battery through gaps, so that the partition plate is polluted, and the performance of the battery is affected.
Disclosure of Invention
The utility model aims at providing a lid in leak protection glue battery to solve above-mentioned technical problem.
In order to achieve the purpose, the utility model is implemented according to the following technical scheme: a middle cover of an anti-glue leakage storage battery comprises a middle cover body, wherein a through hole which is used for being in clearance fit with a storage battery pole is formed in the middle cover body, the 1/3 part of the lower portion of the through hole is a conical counterboring which is coaxial and large at the bottom and small at the top, and a sealing sleeve is arranged in the conical counterboring; the outer side surface of the seal sleeve is jointed with the conical reaming; the upper part in the sealing sleeve is a straight hole section, and the straight hole section is in interference fit with the pole; the lower part of the inner wall of the sealing sleeve is provided with at least one sealing ring which protrudes in the radial direction, and the sealing ring is in interference fit with the pole; the rest part of the inner wall is a conical surface which expands downwards and is in clearance fit with the pole; the seal cover is made of rubber.
Preferably, the sealing sleeve and the middle cover body are integrally formed by injection molding.
Preferably, the lower port of the straight hole section is a conical flaring, and the structure is convenient for pole insertion.
Preferably, the sealing ring is two-way.
Compared with the prior art, the beneficial effects of the utility model are that: 1. the sealing sleeves are arranged on the 1/3 parts of the upper part and the lower part of the pole through hole on the middle cover body, so that on one hand, the length does not influence the subsequent dispensing sealing strength, and on the other hand, glue leakage can be effectively prevented; 2. the upper part of the sealing sleeve is a straight hole section which is in interference fit with the pole, so that the radial sealing degree of the pole is effectively ensured, and a gap between the pole and the sealing sleeve is avoided; 3. the integrated sealing ring arranged at the lower part of the straight hole section of the sealing sleeve further stabilizes and seals the pole in the radial direction, so that the glue leakage phenomenon of the straight hole section is avoided in case of occurrence; meanwhile, the inner wall of the sealing sleeve between the sealing ring and the straight hole section is a conical surface expanding downwards, namely a cavity is formed between the sealing ring and the straight hole section, so that leaked glue can be stored and solidified.
