To achieve the above object, the utility model uses following technical scheme:
A kind of cylindrical lithium ion battery suppresses test device, including air accumulator and the fixed bracket of battery core, on the air accumulator
Equipped with pressure display instrument table and air pressure monitor instrument, the fixed bracket of the battery core is equipped with positioning corresponding with battery core liquid injection hole
Hole, the air accumulator are connected to by pipeline with the location hole.
As a further improvement of the above technical scheme:
The fixed bracket of the battery core includes bottom plate and is fixed on the left plate at bottom plate both ends, right side plate, and left plate and right
The distance between side plate is not less than the length of battery core, and the right side plate is equipped with battery core pressing device.
The battery core pressing device includes the movable plate being set on the inside of right side plate and the rotary shaft being mounted on right side plate, institute
It states movable plate to be flexibly connected by rotary shaft with right side plate, can make movable plate before and after floor length direction by rotating rotary shaft
It is mobile, battery core is pressed on the fixed bracket of battery core.
Rubber pad is additionally provided between the location hole and battery core liquid injection hole.
As shown from the above technical solution, cylindrical lithium ion battery described in the utility model suppresses test device, Ke Yishi
With various sizes of cylindrical electrical core, device to hole groove includes sealing ring, guarantees to suppress the sealing effect in test process；Digital display gas leakage
Pressure monitoring device can intuitively show the air pressure change being filled in battery；The present apparatus is easy to operate, high-efficient, have it is very strong can be real
Shi Xing.
