Embodiment 1
[0030] like figure 1 , figure 2 , image 3 , Figure 4 As shown in the figure, a multiple sealing structure of a storage battery for preventing acid climbing and acid leakage includes a pole 1, a hot-melt adhesive layer 4, a heat shrinkable sleeve 5, and a battery cover 2. The battery cover 2 is provided with a pole hole, so The pole 1 is located in the pole hole on the battery cover 2 , the bottom of the pole 1 is wrapped with a hot melt adhesive layer 4 and a heat shrinkable sleeve 5 , and the pole hole is filled with a sealant 9 .
[0031] Such as figure 2 As shown, the pole hole on the battery cover 2 is designed as a special-shaped hole 3, and the pole 1 is located at the center of the special-shaped hole. The special-shaped hole is composed of a stepped hole 31, a threaded hole 32, and a wedge-shaped hole 33. The stepped hole 31 is located on the top of the special-shaped hole, the bottom of the stepped hole 31 is provided with a threaded hole 32 , the inner side of ...

Abstract
The invention relates to a storage battery multi-sealing structure capable of preventing acid leakage and leakage, which comprises a post terminal, a hot melt adhesive layer, a heat-shrinkable sleeve and a storage battery cover, the lower part of the post terminal is wrapped with the hot melt adhesive layer and the heat-shrinkable sleeve, the storage battery cover is provided with a special-shaped hole, the special-shaped hole is formed by combining a stepped hole, a threaded hole and a wedge-shaped hole, and the threaded hole and the wedge-shaped hole are arranged in the storage battery cover. The pole column is composed of an upper column body, a connecting body and a lower column body, the upper column body is connected with the lower column body through the connecting body, a wedge-shaped elastic body and a screwing pressing block are arranged between the pole column and the special-shaped hole in the storage battery cover, the wedge-shaped elastic body is matched with the wedge-shaped hole, an external thread is arranged on the outer side of the screwing pressing block, and the external thread is matched with the wedge-shaped hole. The external thread on the outer side of the screwing pressing block is matched with the internal thread on the inner side of the threaded hole. And sealant is filled among the connecting body, the upper column body, the stepped hole of the special-shaped hole and the screwing pressing block. The problems of acid leakage and liquid leakage of the storage battery are solved, and the sealing reliability is greatly improved.
Description
technical field [0001] The invention relates to the technical field of storage battery production, in particular to a storage battery multiple sealing structure for preventing acid climbing and acid leakage. Background technique [0002] Valve-regulated sealed lead-acid batteries are now widely used, and users of sealed batteries with larger capacity (such as medium and large-density batteries, electric gas batteries, etc.) generally have longer service life requirements, and the service life requirements are generally more than 3 years or even 5 years. ~8 years. In addition to battery performance to meet the requirements, it is also particularly required that the battery should not have acid leakage, because battery acid leakage is a serious quality defect that will seriously affect the battery life. [0003] The acid leakage of the battery mainly occurs in the sealing part between the terminal pole of the lead-acid battery and the battery cover. Since the existing sealing...
