Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with an anti-leakage protection mechanism. Background Art

[0003] For example, in a distribution box with an anti-leakage protection mechanism with the authorization announcement number "CN219643389U", the mounting plate drives the slide bar to slide along the circular groove through the connecting block, so that the mounting plate is moved out to the outside of the distribution box, thereby increasing the user's operating space and field of vision, so as to facilitate the installation of electrical components in the distribution box or the maintenance of electrical components in the distribution box. However, for the distribution box with an anti-leakage protection mechanism, when there is a leakage inside the distribution box, the operator can still open the distribution box to contact the leaking part inside the distribution box. The distribution box only warns the operator, but when the operator is not paying attention, danger will still occur, which increases the working danger of the distribution box. At the same time, for the distribution box with an anti-leakage protection mechanism, the operator needs to unscrew the screw before moving the mounting plate, but the size of the screw is small, and it is very inconvenient for the operator to turn it, which reduces the working efficiency of the distribution box.
