Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a multi-link pressure-boosting, pressure-maintaining and locking structure. Background Art

[0002] During the battery production process, in order to speed up the absorption rate of the battery electrolyte after injection, improve the production capacity, and inhibit the volatilization of the electrolyte, the battery after injection is placed in a pressure vessel and subjected to a pressurization (nitrogen addition) - vacuum pumping cycle reciprocating operation. In order to realize the pressurization - vacuum pumping cycle process, the pressure vessel must be locked to prevent leakage of the pressure vessel. The boosting device in the existing battery production process is not smooth enough, resulting in swaying when pressing down. At the same time, the boosting pressure is not large enough, which easily causes a lot of noise when the box is lifted; and the structural cost is high. Summary of the invention

A limiting rod is provided at the bottom of the cylinder connecting rod support block, and the bottom of the limiting rod is connected to the absorption box, and a butter nipple is provided on each group of the fixing pins.

[0005] Furthermore, the cylinder connecting rod supporting block is divided into two shapes, one is a cube and the other is a rectangular parallelepiped.

[0006] Furthermore, the middle parts of the sides of the cubic cylinder connecting rod support block are connected to the connecting rod three through fixing pins, and the four corners of the other rectangular cylinder connecting rod support block are connected to the connecting rod three through fixing pins.
