Described fire prevention cover plate both sides contact with described electric-controlled box, wherein the fire prevention cover plate of a side is provided with the arc detent of dodging electric-controlled box screwing post, opposite side is provided with the spacing flange of card envelope electric-controlled box sidewall, described fire prevention cover plate contacts the spacing flange that a side is provided with card envelope lid with lid, described fire prevention cover plate contacts a side and is provided with the arc detent of dodging electric-controlled box screwing post with wire pressing seat.
Described fire prevention cover plate contacts side two ends with wire pressing seat are provided with cable-through hole.
Described fire prevention cover plate lateral surface is provided with handle.
The wherein side that described fire prevention cover plate contacts with electric-controlled box is provided with keeps away wire casing.
The utlity model has following advantage:
1, fire prevention cover plate covers electric-controlled box top, forms effective confined space with electric-controlled box, automatically controlled lid and wire pressing seat; Greatly degree reduces supply and the circulation of combustible air, for spreading of accidental fire trouble provides inhibition environment, thereby has increased safety and reliability that complete machine moves;
2, the fire prevention cover plate periphery of this electric-controlled box adopts position limiting structure, by screw and electric-controlled box, is fixed together, and connects reliably installation, easy removal, efficient;
3, the confined space that fire prevention cover plate and electric-controlled box, automatically controlled lid and junction block form has also been reserved line outlet along walking line position, guarantees not affect cabling and the wiring that shows lead-in wire;
4, the volume of fire prevention cover plate is little, and version is flexible and changeable, can to the components and parts of electric-controlled box inside and top, dodge by the variation of shape, and it can not impact the layout of the components and parts of whole circuit board and electric-controlled box, cabling etc.
Accompanying drawing explanation
