Machinery dedicated electric cabinet

Abstract

The invention discloses a machinery dedicated electric cabinet, which comprises an electric cabinet main body, wherein a display screen is arranged at the top end of the electric cabinet main body; the display screen and the electric cabinet main body are arranged in an embedded manner; an alarming apparatus is arranged at the rear side of the display screen and connected with the display screen in a penetrating manner; an on-off key is arranged at the lower right corner of the display screen and movably connected with the display screen; and a door is arranged at the front side of the electric cabinet main body and movably connected with the electric cabinet main body. A novel technology is adopted by a safety protection device as follows: a crank connected with a sheath firstly clockwiserotates for a set number of turns, and is connected to the alarming apparatus through an inductor to give an alarm when the rotating number of turns exceeds the set number of turns for two or more times or is smaller than the set number of turns, a spiral pipe rotates to the upper part inside a key lock upwards, the spacing distance is induced through the inductor, and no alarm is given when a key is inserted into a key hole after correct treatment and comparison, so that the safety coefficient is increased and the safety of the electric cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a special electrical control box for machinery. Background technique [0002] The electric control box is an intelligent electrical control box that contains one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is fully assembled with structural components by the manufacturer. [0003] However, the existing electrical control boxes for machinery are simple in design, and there are many deficiencies in key locks and safety protection devices, and the safety is low, and the keys configured in the lock holes are easy to be copied and manufactured, and the safety of internal electrical appliances is greatly reduced, and In terms of cables, the connection between the electric control box and the mechanical equipment is single, and it is impossible to achieve a multi-purpose machine. [0004] Therefore, how to d...
