The working principle of the invention is as follows:

When the invention is used, the bottom of the pole body is inserted into concentrated sulfuric acid solution, the upper part of the pole body is provided with a battery cover, the top of the pole body extends out of a hole of the battery cover, the top of the pole body is connected with an electrode joint, the upper part of the electrode joint is screwed and fixed through a nut, a rubber sealing plug is sleeved on the shape of a round table at the upper part of the pole body, the shape of the sealing plug is matched with the round table, the lower part of the sealing plug is inserted into the chassis, a gap is arranged between a circular retaining wall of the chassis and the battery cover, and a circle of outwards protruding parts are arranged at the periphery of the sealing plug and are just inserted into the gap to form a mechanical sealing structure.

The beneficial effects of the invention are as follows:

According to the invention, after the top of the round table-shaped pole body is tightly attached to the rubber sealing ring in the matched shape, the sealing surface is inclined, so that acid liquid below can be effectively prevented from exuding upwards from the sealing gap.

According to the invention, the shape of the chassis forms a mechanical labyrinth sealing structure, so that the rubber sealing ring is plugged into the chassis, the outer ring of the sealing ring is sealed with the annular retaining wall of the chassis, and the inner ring of the sealing ring is sealed with the pole column body, so that a sealing structure with very good sealing performance is formed.

Detailed Description

The invention is further elucidated below in connection with the drawings and the detailed description. It should be understood that the following detailed description is merely illustrative of the invention and is not intended to limit the scope of the invention.

Fig. 1 is a schematic perspective view of the present invention, and as can be seen with reference to the accompanying drawings, the present pole comprises a base 2, a pole body 1 and a chassis 3, wherein the base 2, the pole body 1 and the chassis 3 are integrally cast and formed by lead liquid. The invention is an integrally cast structure, is a whole, and has no gaps among all structures, so that the penetration of acid liquor caused by splicing gaps is avoided.

The base 2 is flat, the pole body 1 stands on the base 2, the base 2 is triangular, each corner is round, and the bottom of the pole body 1 is fused and fixed with one corner. The shape of the base 2 increases the area, and each corner is a round corner, so that the sharp corners are prevented from being discharged, and the sharp corners are prevented from being discharged.

Referring to fig. 1 and 3, the chassis 3 is located in the middle of the pole body 1 or in the middle of the pole body 1, the chassis 3 is in a disc shape, the circumference surrounds the periphery of the pole body 1, the chassis 3 comprises a circular retaining wall 31 and a bottom wall 32 for connecting the circular retaining wall 31 to the pole body 1, the circular retaining wall 31 surrounds the periphery of the pole body 1, a space is reserved between the circular retaining wall 31 and the pole body 1, the circular retaining wall 31 thickens towards the pole body 1 from top to bottom to form a slope, the slope exists, the close fitting degree of the rubber ring and the slope is enhanced, and meanwhile, the vertical plane is avoided, so that acid liquor permeation is caused. The upper surface of the bottom wall 32 is horizontal and vertical to the pole body 1, the lower surface of the bottom wall 32 is thickened from the periphery to the pole body 1, and the lower surface of the bottom wall 32 forms a slope; the slope enhances the securement of the bottom wall 32 to the pole body 1.

Referring to fig. 2 and 3, the top of the pole body 1 is horizontal, and a circular channel 5 extending towards the inside of the pole body 1 is formed in the center of the top, and the circular channel 5 extends to the height of the chassis 3.
