Description

Technical Field

[0001] The utility model belongs to the technical field of battery terminal post correction, and particularly relates to a composite lead wire battery terminal post correction device. Background Art

[0002] Lead-acid batteries have good charge and discharge performance, are safe and stable, and are inexpensive. Currently, they are widely used in electric bicycles, automobiles, USP, energy storage and other fields. In recent years, with the booming development of new energy and energy storage industries, lithium, sodium, fuel cells, etc. have developed rapidly. In order to further improve its market competitiveness and influence, high specific energy and long life have become an inevitable trend in the future development of lead-acid batteries. Therefore, the use of new materials, new processes and new technologies has become a key point that lead-acid batteries urgently need to break through. Composite lead wire is an efficient and high-value application method of new materials and new processes in lead-acid batteries. Due to the large differences in materials and structures between composite lead wire batteries and traditional lead-acid batteries, it is extremely easy to cause the battery terminal posts to be skewed and uneven in height, which not only affects the appearance, but also easily causes acid leakage at the terminal posts during the cyclic charge and discharge process. Therefore, it is necessary to correct the terminal posts.

[0003] For example, there is a Chinese patent with the publication number CN217701121U, which relates to an automatic correction device for lead-acid battery terminal posts, including: a mounting table, with guide frames symmetrically arranged left and right on both the front and rear sides of the top of the mounting table; sliding frames, with sliding frames slidably arranged between the two front guide frames and between the two rear guide frames; a cylinder, with a cylinder arranged inside the sliding frame; and a correction plate, with a correction plate arranged on the telescopic rod of the cylinder. By the staff rotating the handle in the reverse direction, the bidirectional screw rod drives the two clamping plates to fix the lead-acid battery inward, preventing the lead-acid battery from moving during correction, so as to achieve the purpose of fixing the lead-acid battery. However, the structure of this patent is complex and the cost is high. Summary of the Utility Model

[0007] A vertical fixed shaft, provided with a screw part connected to the horizontal fixed seat, the screw part is also connected to a handle part and a fixed part provided with a disc, and the disc is connected with a plurality of limit posts.

[0008] In this technical solution, a composite lead wire battery terminal post correction device includes a horizontal fixed seat and a vertical fixed shaft. The horizontal fixed seat includes three circular rings and two connecting components.

[0019] The present utility model is further configured as follows: The limiting columns are circumferentially distributed at the bottom edge of the disc, and the bottom ends of the limiting columns are in contact with the upper edge of the middle circular ring.

[0020] In this technical solution, when the screw is completely screwed into the threaded hole of the battery terminal post copper part, the bottom end of the limiting column just abuts against the upper edge of the middle circular ring, playing a limiting role to prevent the screw from being screwed in too deep and causing the battery terminal post to deform due to stress.
