[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4, a new energy battery pack box airtight plug, comprising: a sleeve 1, the interior of which is a hollow structure, the sleeve 1 can be sleeved on the explosion-proof valve port, and plays a role of limiting; a movable shaft 3, movably installed in the sleeve 1; a plugging cover 4, fixedly connected to the first end of the movable shaft 3, the plugging cover 4 can seal the explosion-proof valve port, and the movement of the movable shaft 3 drives the plugging cover 4 to seal or release the explosion-proof valve port; a cover plate 2, mounted on the first end of the sleeve 1, and the movable shaft 3 is movably mounted on the cover plate 2; a driving mechanism, mounted on the cover plate 2, and the driving mechanism can drive the movable shaft 3 to move. The movable shaft 3 and the plugging cover 4 are driven to move by the driving mechanism. It is convenient for the box to be airtight tested. At the same time, the explosion-proof valve needs to be installed when the explosion-proof valve plug is removed, and it has the functions of reminding and preventing errors.

[0028] The driving mechanism includes: a connecting seat 6, a first end of which is hinged to the cover plate 2; an operating rod 7, a second hinge point 72 of which is provided, and the operating rod 7 is hinged to the second end of the movable shaft 3 via the second hinge point 72; a first hinge point 71 of which is provided on the operating rod 7, and the operating rod 7 is hinged to the second end of the connecting seat 6 via the first hinge point 71. The swinging of the operating rod 7 and the relative movement of the first hinge point 71 and the second hinge point 72 achieve the purpose of pulling or releasing the movable shaft 3, thereby driving the blocking cover 4 to block or release the explosion-proof valve port.

[0029] A mounting base 5 is fixedly provided on the cover plate 2, and a first end of the connecting base 6 is hinged on the mounting base 5. The mounting base 5 facilitates the installation of the driving mechanism.

[0030] The plugging cover 4 is provided with a sealing ring 41 adapted to the explosion-proof valve port, thereby achieving a sealed connection between the plugging cover 4 and the explosion-proof valve port.

[0031] The cover plate 2 is provided with threads, and the cover plate 2 is connected to the sleeve 1 through the threads, so as to facilitate the installation between the cover plate 2 and the sleeve 1.

[0032] A handle is provided at the end of the operating rod 7 to facilitate operation of the operating rod 7 .

[0033] Before the airtight test, align the airtight plug with the explosion-proof valve port. The magnet on the shell will adsorb the tooling to the box body. Use the quick clamp at the tail of the tooling to cover the middle pressure cover of the plug on the explosion-proof valve port. The pressure plate in the middle of the pressure cover will block the explosion-proof valve port. After the airtight test, release the quick clamp, take out the plug, and install the explosion-proof valve. It has reminder and error prevention functions.

[0034] After adopting the above structure, it is convenient to carry out air tightness test on the box. At the same time, the explosion-proof valve needs to be installed when the explosion-proof valve plug is removed, which has the functions of reminder and error prevention.
