[0002] A moisture-proof electric cabinet is a cabinet made of steel materials to protect components to work normally. The manufacturing materials of electric cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are relatively lighter and softer in material, and are more suitable for the manufacture of electric cabinets. Electric cabinets are widely used mainly in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Moisture-proof electric cabinets use various dehumidification technologies to effectively reduce the humidity inside the cabinet, so as to achieve the purposes of moisture-proof, mildew-proof, anti-oxidation, rust-proof, and anti-microscopic moisture absorption.

[0003] After a large number of searches, it is found that: in the Chinese utility model patent column: the publication number CN220138942U discloses a wire inlet device of an electric cabinet, including an electric cabinet main body and a wire inlet structure; the wire inlet structure is fixedly installed on the back of the electric cabinet main body, and the wire inlet structure includes a control device, a housing, a bidirectional motor, a worm, a worm gear, a threaded rod, two moving blocks and a guide rod; the control device is fixedly installed on the back of the electric cabinet main body; the housing is fixedly installed on the back of the electric cabinet main body; a bidirectional motor is fixedly installed inside the housing, and a worm is fixedly installed at the driving end of the bidirectional motor; a threaded rod is movably connected inside the housing, and the thread directions of the two ends of the threaded rod are opposite; a worm gear is fixedly installed in the middle of the threaded rod, two moving blocks are screwed on the threaded rod, and are symmetrically distributed inside the housing; the tops of the two moving blocks are slidably connected with a guide rod.

The wire inlet holes adjusted by the moving blocks only fit the same type or size of cables. When encountering cables with different outer diameters, the device cannot effectively fix and limit each cable, so the applicability of the bottom wire inlet device of the moisture-proof electric cabinet is reduced.
