Translation-type hinge of vacuum chamber door of box-type vacuum packaging machine
The invention relates to a translation-type hinge of a vacuum chamber door of a box-type vacuum packaging machine, which comprises a hinge body installed between the door and a door frame, the door and the door frame are sealed by a sealing rubber strip, the hinge body comprises a hinge fixation base and a hinge movable base, the hinge fixation base and the hinge movable base are hinged by a hinge shaft, a waist-shaped hole is disposed in the hinge movable base, the hinge shaft is movably installed in the waist-shape hole and can move between round holes in two ends of the waist-shaped hole, and a spacing between centers of the round holes in the two ends of the waist-shaped hole is bigger than or equal to a spacing between the sealing strip and the door frame after closing of the door and the door frame. In the translation-type hinge of the vacuum chamber door of the box-type vacuum packaging machine provided by the invention, the hinge body can realize translation to adjust the spacing between the door and door frame and guarantee that leakage will not happen and the rubber trip will not be deformed under squeezing and then damage a sealing effect under a negative pressure. In addition, the hinge is simple in structure and can satisfy production demands.
