Airtight tool for rapidly and efficiently detecting new energy automobile battery box body

The invention discloses an airtight tool for rapidly and efficiently detecting a new energy automobile battery box body, which comprises a BASE plate, a sealing strip is arranged on the BASE plate, the battery box body covers the BASE plate through an upper opening, and an upper cover assembly surface of the battery box body is consistent with the sealing strip on the BASE plate in shape and just correspondingly abuts against and contacts with the sealing strip on the BASE plate. A plurality of filling blocks are also arranged on the BASE plate and are used for filling the internal space of the battery box body; the clamping mechanism is used for pressing the battery box body from the upper part so as to compress the sealing strip, so that a sealing cavity is formed between the battery box body and the BASE plate; and the inflation inlet is formed in the BASE plate, and the sealed cavity is inflated through the inflation inlet. According to the invention, detection in a traditional clamp form is beneficial to
