Claims (1)

[Scope of utility model registration request] A high-voltage equipment box with an openable and closable inspection cover mounted on an electric vehicle has a first lock mechanism that engages and locks the inspection cover in the closed state with respect to the box body by rotation of a lock bar, and a first lock mechanism that locks the inspection cover in the closed state with respect to the box body. a second lock mechanism that interlocks to allow rotation of the lock bar of the first lock mechanism when the inspection cover is closed and prevents it when the inspection cover is open; an operating lever that interlocks with the lock bar of the first lock mechanism; It has a lock that restricts movement, and by unlocking the lock with the same key as the electric vehicle's pantograph lift switch, the operating lever can be rotated to lock and release the inspection cover of the first lock mechanism. and a third lock mechanism that can lock and remove the key only when the operation lever of the first lock mechanism is rotated back to the inspection cover closed and locked state. High pressure equipment box.
