second link assemblies

130 and 140;

the stop block 170 is disposed at one end of the first sliding rail 151 and/or the second sliding rail 152 away from the door panel 100;

when the rack 160 is at the lowest position, the first mounting plate is located at one end of the first sliding rail 151 near the door panel 100, so that when the door panel 100 is pulled out of the disinfection chamber, the sliding rail assembly 150 and the rack 160 move relative to the fixed side plate and the mounting plate; when the stop 170 abuts the first and/or second mounting plates 192, the slide rail assembly 150, the rack 160, and the mounting plates rise as the first and

second link assemblies

130, 140 oscillate.

In particular, in this embodiment, there are many kinds of sterilizing apparatuses, such as sterilizing boxes, sterilizing cabinets, etc., for sterilizing tableware. The rack 160 is used to provide a placement space or a placement position for the articles to be sterilized, but may also provide a placement position for a container for accommodating the articles to be sterilized, such as a bowl basket. The first and second

fixed side plates

110 and 120 serve to provide a suspension force for the first and

second link assemblies

130 and 140 and the rack 160. When the rack 160 is located at a low position, under the action of external force, the rack 160 translates along with the sliding rail assembly 150 to the outside of the disinfection cavity, when the sliding rail assembly 150 moves to a preset position, the stop block 170 located at the end part of the sliding rail assembly 150 is abutted to the mounting plate and pushes the mounting plate (the lower end of the connecting rod assembly) to move outwards, at this time, the movement of the rack 160 is converted from translation to circular movement with the hinge point at the upper end of the connecting rod assembly as the center, the effective length of the connecting rod assembly is circular movement with the radius, and the rack 160 rises along with the swinging of the connecting rod assembly. Wherein, the first fixed side plate 110 and the second fixed side plate 120 are respectively arranged at the upper parts of the left side wall and the right side wall of the disinfection cavity.
