Description

Technical Field

[0002] In the process of electrode fixing of lead-acid batteries, electrode rivet welding is usually adopted.

[0003] For example, the authorization announcement number CN217361709U is an electrode rivet structure for lead-acid batteries. The above document passes the bottom plug through the electrode sheet opening so that the connecting clip and the bottom connecting sheet are placed on the top of the electrode sheet, and then the bottom connecting sheet is placed on the bottom of the electrode sheet by bending the bottom connecting sheet. Zhihai bends and tears off the excess bottom connecting sheet according to the length of the electrode sheet through the separation indentation, and welds the contact surface between the connecting clip, the bottom connecting sheet and the electrode sheet through electric tin. The contact connection surface between the connecting clip and the bottom connecting sheet and the connecting gasket is increased, and the connection strength between the electrode sheet and the riveted structure is improved. At the same time, the operation difficulty caused by the small welding point is reduced, and the connection clip and the bottom connecting sheet and the connecting gasket are prevented from falling off. However, during the use of the electrode rivet structure for lead-acid batteries in the above document, Since the connection clip, the bottom connecting piece and the electrode piece are connected by electric tin welding, as the use time of the lead-acid battery increases, the connection clip, the bottom connecting piece and the electrode piece are prone to open welding, which makes the connection between the three easy to loosen, causing the lead-acid battery to have poor contact during charging and discharging, thus affecting the use of the lead-acid battery. In the process of using the electrode rivet structure for lead-acid batteries in the above-mentioned document, when the length of the bottom connecting piece is adjusted according to the length of the electrode piece, the staff needs to manually bend and tear off the bottom connecting piece through the separation indentation of the bottom electrode piece. During the bending and tearing process, the bottom connecting piece is made of metal and has a relatively high hardness, which makes it more laborious for the staff to bend and tear it off, and it is not convenient to adjust the length of the bottom connecting piece.

[0032] Working principle:

[0033] Before welding with the lead-acid battery electrode sheet, a person pulls the pull ring 4041 upwards, and the pull ring 4041 drives the sleeve rod 401 to move upward along the inner wall of the sleeve 7 through the support block 404, and the sleeve rod 401 drives the spring 405 to compress, and the sleeve rod 401 drives the positioning block 403 to rotate downward at the same time through the guide blocks 402 on both sides, and then the connecting clip 601 and the bottom connecting piece 602 are placed on the top of the electrode sheet, and the sleeve 7 is passed through the opening of the electrode sheet, and then the bottom connecting piece 602 is bent, and then the pull ring 4041 is released, and the positioning block 403 is affected by the elastic force of the spring 405 to press against the right side connecting block 301;

[0034] According to the length of the electrode sheet, the connecting block 301 at the corresponding position is disassembled. The staff rotates the rotating block 302, and the rotating block 302 drives the screw 305 to rotate. During the rotation of the screw 305, the block 304 is restricted by the cavity 3013. The block 304 moves outward along the thread groove of the screw 305, so that the block 304 is connected to the square groove 3011, so that the connecting block 301 at this position is disassembled, and the contact surfaces between the connecting clip 601, the bottom connecting piece 602 and the electrode sheet are welded by electric tin, and then the bottom plug 5 is passed through the sleeve rod 401 and the sleeve 7 at the same time, and then the connecting gasket 2 is threadedly connected with the threaded portion 701 of the sleeve 7.
