Hinged door type observation port structure

Abstract

The utility model discloses a hinge door type observation hole structure is arranged in the furnace body of kiln, aims at solving the traditional bolt connection observation hole dismounting is complicated, and the problem of easy material and ash leakage. It includes observation hole and hole cover, and the one end of hole cover is hinged to the furnace body through the hinge, and the other end is equipped with lock groove, and the furnace body is correspondingly equipped with bolt assembly, and there is sealing assembly between hole cover and furnace body. Bolt assembly contains support, pivot, screw rod and compression block, and screw rod can turn into lock groove extrusion hole cover, and the both sides of furnace body are equipped with compression mechanism, and are linked through linkage assembly and screw rod, and when screw rod rotates, drive compression board to extrude the both sides of hole cover by conical surface, and form even compression force. The structure realizes convenient opening and closing through the hinge, ensures reliable sealing in the mode of "central main compression + two sides auxiliary compression", simplifies the operation of multiple bolts into single screw rotation, improves operation efficiency, and solves the problems of traditional structure dismounting trouble, bolt easy loosening and material leakage.
