The invention relates to a novel heating furnace door efficient maintenance-free sealing structure. The sealing structure comprises a furnace door, wherein a cavity is formed in the side of the furnace door, the side of the furnace door communicates with a through hole of the cavity, a clamping plate is installed in the through hole, and a rolling wheel is movably installed on the inner side of the clamping plate; first hinges symmetric with each other and second hinges symmetric with each other are arranged in the cavity, the left ends of the first hinges are movably connected with the innerside wall of the cavity, the right ends of the second hinges are movably connected with the clamping plate, and the right ends of the first hinges are movably hinged to the left ends of the second hinges through hinge shafts; and a micro bearing is arranged between the middle of the inner sides of the first hinges and the inner sides of the second hinges, and the two sides of the outer ring of themicro bearing are movably connected with one ends of connecting rods. The sealing structure is reasonable in structure and convenient to use, the structure of an existing furnace door is improved mainly, the rolling wheels of the furnace door is improved into an adjustable rolling wheel, so that the problem that the rolling wheel is squeezed in a slideway due to the fact that the furnace door isdeformed due to long-time high temperature is solved, and a lot of later maintenance is reduced.
Description
technical field [0001] The invention relates to the field of high-temperature heat treatment heating furnaces, in particular to a novel high-efficiency and maintenance-free sealing structure for the furnace door of the heating furnace. Background technique [0002] Existing high-temperature heating furnace doors are usually made of cast iron. After long-term use, the furnace door is easily deformed. As a result, the furnace door rollers of the lifting mechanism will also hinder the normal lifting operation due to deformation, and the furnace door cannot be opened or closed normally, which affects production. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect that the deformation of the furnace door in the prior art affects the movement of the rollers, and provide a new type of high-efficiency and maintenance-free sealing structure for the furnace door of the heating furnace. [0004] In order to solve...
