The rack holes 91 mesh with the unlocking gear 74, causing the two pull tabs 9 meshing with the unlocking gear 74 to move up and down respectively. When the door is closed, the key core 73 is installed in the lock bottom cover 71.

[0032] When the door is normally closed, the latch 619 is screwed into the adjacent side door frame. Both the upper and lower connecting rods 25 are inserted into the upper and lower round rod roller assemblies 1 (i.e., the upper door frame and lower door frame, respectively). The bolt 52 is inserted into the bolt through hole 42 within the adjacent explosion-proof fastener 4, locking the door. When the pressure inside the energy storage cabinet suddenly increases, the pressure acts on the door, causing deformation of the pull rod 8, connecting rod 25, and latch 619. Without the explosion-proof fastener 4 and explosion-proof bolt 5, the door will suddenly explode under the pressure inside the energy storage cabinet, potentially injuring personnel outside. Since the rigidity or strength of the explosion-proof bolt 5 and the explosion-proof fastener 4 in this application is designed to be 10-30 times that of the bolt tension lock 6, with the explosion-proof fastener 4 and the explosion-proof bolt 5, the door will burst open a gap under the pressure inside the energy storage cabinet, and the pressure inside the door will be released to a certain extent. However, the door will still be held in place by the explosion-proof fastener 4 and the explosion-proof bolt 5, thus eliminating the risk of injury to personnel outside the energy storage cabinet.
