Embodiment Construction
[0024] Such as figure 1 As shown, the present invention includes a pole 1 disposed in the pole hole of the battery cover 3, a pressure ring 2 disposed in the pole hole, a gasket 5, a sealing ring 6, and a sealant 4. The pressure ring 2 and the gasket 5 1. The sealing ring 6 is set on the pole 1 and arranged sequentially from top to bottom. The sealant 4 is filled in the gap between the pressure ring 2 and the inner wall of the pole hole, and between the pressure ring 2 and the pole 1.
[0025] Such as figure 1 , 3 As shown, the upper part of the pole 1 is a copper core, and the lower part is a lead piece. The upper part of the lead piece is a circular frustum, and the pole hole 32 matched with the upper circular frustum of the lead piece is a non-conductor that gradually shrinks inward. Equal-diameter round holes, the inner and outer peripheral surfaces of the sealing ring 6 are respectively kissed with the outer peripheral surface of the circular platform of the lead part a...

The invention discloses a storage battery post and storage battery cover post hole sealing structure, which comprises a post arranged in a battery cover post hole, a sealing ring arranged in the post hole, a sealant, and a compression ring arranged in the post hole, wherein the compression ring and the sealing ring are sleeved on the post and are arranged from top to bottom in turn; and the sealant is filled in gaps between the compression ring and an inner wall surface of the post hole and between the compression ring and the post. Because a sealing effect between the battery post and the post hole is good, the battery quality is effectively guaranteed, the sealing structure is particularly suitable for a standby battery and an energy storage battery, and even if the structure is used for three to five years, the phenomenon of post acid creep corrosion cannot occur. Meanwhile, because the consumption of the sealant is low, the time of curing the post sealant is shortened, the production efficiency is improved, and the environmental pollution is lightened.
Description
technical field [0001] The invention relates to a valve-controlled lead-acid storage battery, in particular to a sealing structure for a storage battery pole post and a battery cover pole post hole. Background technique [0002] With the rapid development of battery products in our country, in the battery manufacturing process, especially in the battery pole sealing process, O-rings or asbestos ropes are commonly used to press into the pole holes and inject resin glue for sealing. There are also manufacturers who add plastic nuts to the O-ring for compression, and then inject sealant to seal it. Although the sealing effect is improved a lot in the short term, if the backup and energy storage batteries are used for three to five years, with the growth of the pole plate, the pole will be damaged. Acid corrosion still occurs, and in the production process, too much sealant is used, which not only affects the improvement of production efficiency due to the long curing time of th...
