Problems solved by technology
However, it is regrettable that the existing sealing methods for embedded poles will cause acid leakage of the battery due to the sealing of the poles, which will directly lead to the shortening of the life and service time of the battery, which will corrode the poles and pollute the environment. Increased maintenance and use costs

Embodiment Construction
[0022] use Figure 1 to Figure 4 The sealing method of the pole post of the lead-acid battery of the present invention is described as follows.
[0023] Such as figure 1 and figure 2 Shown, the sealing method of a kind of lead-acid battery pole of the present invention, this sealing method comprises the steps:
[0024] Step 1: setting at least one annular groove on the outer surface of the lead sleeve of the pole;
[0025] Step 2: Nest the combined sealing ring in the annular groove in Step 1;
[0026] Step 3: Put the lead sleeve covered with the combined sealing ring in step 2 on the injection mold of the battery cover, and injection mold the plastic battery cover, so that the lead sleeve and the battery cover are connected to each other as a whole;
[0027] Wherein, the combined sealing ring in the step 2 includes an elastic base 1 and a sealing ring 2, the elastic base 1 is installed in the groove of the movable shaft 3, the elastic base 1 is a ring structure, and the ...

The invention belongs to the technical field of lead-acid battery preparation, and specifically relates to a method for sealing a pole of a lead-acid battery. The sealing method comprises the following steps: setting at least one annular groove on the outer surface of the lead sleeve of the pole; Step 1 The combined sealing ring is nested in the annular groove in the center; the lead sleeve with the combined sealing ring is placed on the injection mold of the battery cover, and the plastic battery cover is injection molded, so that the lead sleeve and the battery cover are connected as one. . The invention adopts a combined sealing ring and injection molding to realize the sealing of the pole post of the lead-acid battery, and increases the extrusion force of the sealing ring through the principle of thermal expansion of mercury liquid to improve the sealing effect.
Description
technical field [0001] The invention belongs to the technical field of lead-acid battery preparation, and in particular relates to a sealing method for a pole post of a lead-acid battery. Background technique [0002] Whether the lead-acid batteries currently on the market are closed maintenance-free or open, the sealing method for embedded poles is mainly to adjust the injection pressure parameters during injection molding to ensure the sealing of the lead sleeve. However, it is regrettable that the existing sealing methods for embedded poles will cause acid leakage of the battery due to the sealing of the poles, which will directly lead to the shortening of the life and service time of the battery, which will corrode the poles and pollute the environment. Increased maintenance and use costs. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention proposes a method for sealing the pole of a lead-acid battery. In...
