an arc-shaped wheel piece (505) is installed at one end, far away from the built-in support (9), of the transmission telescopic rod (503);
a sliding guide rod (504) is arranged in the sliding groove in a relatively sliding manner, and the upper side and the lower side of the sliding guide rod (504) are symmetrically connected with side buckle assemblies (8) in a transmission manner;
the side buckle assembly (8) is engaged with and fixed to a clamping piece arranged at a corresponding position on the peripheral equipment cabinet (1), so that the sealing door body (2) is in sealing connection with the peripheral equipment cabinet (1) and then is locked and fixed.
5. The power control cabinet with the function of preventing false opening according to claim 4, characterized in that: the built-in support (9) is matched and connected with the clamping plate (6), a plurality of arc-shaped elastic sheets (902) are arranged on the inner circumference of the built-in support (9) in an array mode, and a plurality of connecting springs (901) are arranged between each arc-shaped elastic sheet (902) and the built-in support (9) in parallel;
and the cross section of one end of the clamping and fixing plate (6) extending into the built-in support (9) is in a water drop shape.
6. The power control cabinet with the function of preventing false opening according to claim 4, characterized in that: the central rotating shaft (502) is wound with a built-in torsion spring, the built-in torsion spring enables the central rotating shaft (502) to rotate anticlockwise under a common state through the elastic action of the built-in torsion spring, and the built-in support (9) is driven to slide downwards by the transmission telescopic rod (503).
7. The power control cabinet with the function of preventing false opening according to claim 4, characterized in that: the side buckle assembly (8) comprises a rotating wheel shaft (802), a transmission rod piece (801) and a locking rod (803), wherein the rotating wheel shaft (802) is symmetrically arranged in the sealing door body (2) in a vertically and relatively rotatable manner, one end of the rotating wheel shaft (802) is hinged to the sliding guide rod (504) through the transmission rod piece (801), and one side, away from the sliding guide rod (504), of the rotating wheel shaft (802) is hinged to the locking rod (803);
the tail end of the locking rod (803) is also provided with a bending locking piece which is clamped with the peripheral equipment cabinet (1).
