Abstract

The invention provides an airtightness test protection device of a cell box. The protection device comprises a protection cover, a base plate, a big knob, a small knob, a pair of upper guidance rods, a pair of lower guidance rods, a pair of cranks and a pair of hooks. Thus, a problem of deformation of a box cover during an airtightness test of the cell box can be solved, the yield passing rate during the airtightness test is improved, and the stability of the whole performance of the cell box is ensured. In addition, the protection device is advantaged by rapid and highly efficient installation and assembly.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of batteries, in particular to a battery box air tightness test protection device. [0003] 【Background technique】 [0004] Whether the sealing of the battery box is good will directly affect whether the waterproof effect is up to standard, so the airtightness test of the battery box is carried out. At present, the air-tightness test of the battery box generally adopts the method of inflating, so that the internal pressure of the battery box increases rapidly, which easily causes the box cover to deform and bulge, and it is difficult to return to the original state. [0005] 【Content of invention】 [0006] The purpose of the present invention is to provide a battery box airtightness test protection device capable of avoiding quality defects caused by the airtightness test of the battery box. [0007] In order to achieve the above object, the present invention provides a battery box air tightness te...
