Embodiment Construction

[0010] The present invention will be further described below in conjunction with drawings and embodiments.

[0011] exist figure 1 Among them, a battery cover 3, a rectangular sealing ring 4, a washer 5, and a nut 6 are sequentially installed on the battery pole 1 embedded with copper-zinc parts 2. The battery pole 1, the nut 6 and the battery cover 3 form a cavity, and the diameter of the inner hole of the nut 6 should be larger than the diameter of the battery pole, so that a section of annular ring communicating with the cavity is formed between the battery pole 1 and the nut 6 Gap, the width of the gap is 2 ~ 5mm, and the height is 3 ~ 10mm; the pole glue 7 is filled in the cavity and the annular gap to form a glue seal. Since the present invention increases the gap, the sealing height of the glue seal is increased by The original h1 is increased to the current h2, which greatly enhances the sealing effect.

[0012] In addition, the inner hole of the nut 6 is a two-layer...

Abstract

The invention relates to a storage battery sealing device. The storage battery sealing device comprises a battery pole, a battery cover, a sealing ring, a gasket, a nut and pole glue. The battery cover, the sealing ring, the gasket and the nut are orderly sleeved on the battery pole. The nut is provided with external threads and the external threads engage with internal threads of the battery cover. The battery pole, the nut and the battery cover form a cavity. An inner diameter of the nut is greater than an external diameter of the battery pole so that a gap communicated with the cavity is formed. The pole glue is filled into the cavity and the gap. An inner wall of the nut is provided with at least one annular groove for enlarging the gap. In the storage battery sealing device, a meeting surface of the pole glue and the battery pole has a long longitudinal length and thus it is effectively avoided that sulfuric acid in a battery climbs along a side of the battery pole and then is leaked; and a battery charge-discharge life is prolonged.

Description

technical field [0001] The invention relates to a battery sealing device, in particular to a storage battery sealing device. Background technique [0002] At present, the following methods are usually used for the sealing of lead-acid battery poles: ①The purpose of mechanical sealing is achieved by compressing soft rubber sealing rings, such as O-rings, rectangular rings, etc.; ②Directly applying adhesives, such as epoxy resin, polyurethane Glue, etc., is poured into the sealing part to achieve the purpose of adhesive sealing; ③ Embed a lead sleeve in the sealing part of the battery cover, and then weld the lead sleeve and the corresponding pole to achieve the purpose of sealing the lead sleeve. It is a common solution to directly pour the adhesive into the sealing part to achieve the purpose of adhesive sealing. However, the actual use shows that due to the short length of the bonding surface between the pole glue and the battery pole in these schemes, the sealing strength...
