Metering cabinet

The invention provides a metering cabinet comprising a cabinet body (10), an upper cabinet door (11), a lower cabinet door (20) and a partition (30) arranged between the upper cabinet door (11) and the lower cabinet door (20). The lower cabinet door (20) is slidably arranged on the cabinet body (10) vertically. The metering cabinet further comprises a locking device comprising a supporting portion (40), a locking pin (50) and a locking rod (60); the locking rod (60) comprises an unlocking position and a locking position limiting the movement of the lower cabinet door (20), and the locking pin (50) matches with the locking rod (60) to allow the locking rod (60) to locate in the locking position; when the locking rod (60) is located in the locking position, the bottom of the locking rod (60) and the lower cabinet door (20) are in abut connection, and the locking pin (50) is limited by the supporting portion (40). By the aid of the technical scheme, the problem that the lower cabinet door of an existing metering cabinet is prone to opening in the prior art is solved effectively.
