Liftable and foldable disinfection box

A liftable and foldable disinfection box, comprising

• an upper half box body and a lower half box body;
• wherein
• the upper half box body is sleeved on the lower half box body in a relatively liftable manner;
• a positioning mechanism is mounted on the upper half box body;
• the upper half box body and the lower half box body are fixed by locking the positioning mechanism, or the upper half box body is liftable relative to the lower half box body by unlocking the positioning mechanism;
• a disinfection chamber is formed between the upper half box body and the lower half box body,
• the disinfection chamber has a chamber door,
• the positioning mechanism comprises a rack track, a toothed block and a pressing block;
• a rib is formed on the upper half box body, and the rib has a hollow tube;
• a bottom of the hollow tube is closed and a top of the hollow tube has an opening;
• the opening is located on a top surface of the upper half box body;
• a side surface at the bottom of the hollow tube has a side opening;
• the lower half box body has a groove, and the rack track is formed on an inner wall of the groove, wherein the inner wall of the groove corresponds to the side opening at the bottom of the hollow tube;
• the toothed block is disposed at the bottom of the hollow tube;
• an elastic member is disposed between the toothed block and an inner wall of the hollow tube;
• under an action of the elastic member, an engaging tooth of the toothed block extends out from the side opening at the bottom of the hollow tube and the engaging tooth fits with the rack track;
• a lower inclined pushing surface is formed on an upper portion of the toothed block;
• the pressing block is inserted into the hollow tube;
• an upper end of the pressing block is located at the opening of the hollow tube;
• an upper inclined pushing surface is formed at a lower end of the pressing block;
• the upper inclined pushing surface fits with the lower inclined pushing surface, when the pressing block is pressed, the toothed block is driven to overcome the action of the elastic member, and the engaging tooth is separated from the rack track.
