Abstract
The utility model provides an anti-explosion and antic-corrosion operation column, and relates to the field of anti-explosion electric appliances. The anti-explosion and antic-corrosion operation column is composed of a box body, button switches and a wire inlet port. The box body is that one side of a connecting cavity and one side of a component cavity are fixedly connected, and the connecting side wall is provided with a through hole. The opposite side wall of the connecting cavity is provided with the wire inlet port. The connecting cavity and the component cavity are provided with cooperatively-used cover bodies which are connected via a screw rod. A connecting terminal bar is fixed in the connecting cavity. The cooperatively-used cover body of the component cavity is provided with a master instruction knob switch, two button switches, two display lamps and a current meter transparent display window. The button switch main bodies, the display lamp bodies and a current meter are fixed on the corresponding positions of the lower part of the cover bodies. The wire inlet port outside the connecting cavity is provided with an inlet wire sealing screw cap. The anti-explosion and antic-corrosion operation column is reasonable in structural design. The component cavity and the connecting cavity are arranged so that reduction of corrosion rate of corrosive gas in the maintenance process is facilitated. The anti-explosion and antic-corrosion operation column is high in anti-explosion and antic-corrosion performance, long in the service life and low in maintenance frequency so that continuity of production is facilitated.
Description
Technical field
The utility model relates to explosion-proof electric apparatus field, relates in particular to explosion proof and corrosion protection operation post.
