The working principle of the door body connecting structure of the utility model is briefly explained as follows: the configuration of the hinge 3 in fig. 3 and 5 corresponds to the door closing state of the door 2, in this state, the door 2 is in close contact with the edge of the cabinet 5, as shown in fig. 5, the compression spring 308 is in the compressed state at this time, so the push wheel 306 applies a reaction force to the driving lug 3021, since the push wheel 306 is located on the left side of the driving lug 3021 in the view of fig. 5 at this time, the swing arm 302 receives a clockwise moment in the view of fig. 5, so that the door 2 is pressed on the cabinet 5, the sealing performance of the door 2 is better, and the door 2 can be prevented from being opened due to misoperation. When the door body 2 needs to be opened, the door body 2 is pulled by hand, as shown in fig. 7, the swing arm 302 swings counterclockwise relatively, in the process, the driving lug 3021 pushes the push wheel 306 open by the force of the hand, the compression spring 308 is further compressed, so that the push wheel 306 moves to the position shown in fig. 7 relatively, as described above, in this state, the contact point of the driving lug 3021 with the push wheel 306, the center of the push wheel 306 and the center of the slide seat rotating shaft 305 are all on the same straight line, so after the hand is released, because the thrust direction of the compression spring 308 passes through the center of the slide seat rotating shaft 305, the force arm of the compression spring 308 to the slide seat rotating shaft 305 is approximately zero, in the state of fig. 7, the thrust of the compression spring 308 generates a torque to the swing arm 302 around the swing arm rotating shaft 304 to counteract the torque to the swing arm 302 around the swing arm rotating shaft 304, and the thrust of the compression spring 308 instead makes the swing arm 302 press on the slide seat, in the state of fig. 7, since the swing arm rotating shaft 304 drives the sliding base 303 to move downwards, the extension spring 312 generates an upward pulling force on the sliding base 303, and this pulling force, in combination with the downward pushing force of the compression spring 308, increases the indirect static friction between the swing arm 302 and the sliding base 303 and between the swing arm 302 and the hinge housing 301, so that in the state of fig. 7, the swing arm 302 and the hinge housing 301 form a relative self-locking state, i.e. the swing arm 302 and the hinge housing 301 are relatively stationary, and in this state, because the force arm of the gravity of the door body 2 to the swing arm rotating shaft 304 is relatively short, the gravity action of the door body 2 is not enough to break the self-locking state, and the door body 2 can hover at a position corresponding to the relative angle between the swing arm 302 and the hinge housing 301 of fig.. When the door body 2 is opened by hand, the driving protrusion 3021 crosses the push wheel 306 by hand force, so that the self-locking state is released, and during the downward-turning opening process of the door body 2, as shown in fig. 9, "M" in fig. 9 represents the center of gravity of the door body 2, "Q" in fig. 9 represents the swing arm rotating shaft 304, "T" in fig. 9 represents the resultant moment resisting the downward-turning swing of the door body 2, "G" in fig. 9 represents the gravity of the door body 2, and "X" in fig. 9 represents the moment arm of the gravity of the door body 2 to the swing arm rotating shaft 304, as seen in comparison between fig. 9 and fig. 10, when the door body 2 is turned downward gradually, the moment arm X also increases gradually, the moment of the gravity G of the door body 2 to the swing arm rotating shaft 304 increases gradually, as shown in fig. 7 and fig. 8, correspondingly, during the swinging process of the swing arm 302 relative to the hinge housing 301, the swing arm 302 drives the sliding base 303 to move through the sliding base, because the pulling force of the extension spring 312 is proportional to the extension length, the moment applied by the extension spring 312 to the swing arm 302 increases gradually, and the indirect friction between the swing arm 302 and the hinge housing 301 and between the swing arm 302 and the sliding base 303 also increases gradually, the resultant moment of the moment generated by the friction to the swing arm rotating shaft 304 and the moment generated by the extension spring 312 to the swing arm rotating shaft 304 is similar to the resultant moment T resisting the downward-turning swing of the door body 2, when the specification of the extension spring 312 is set to match the weight of the door body 2, the door body 2 can hover or slowly turn down within the range of the swing angle between the state of the corresponding swing arm 302 in fig. 7 and the state in fig. 8, so that the disinfection cabinet with the door body connection structure of the present invention has better use effect, thereby avoiding the phenomenon that the door body 2 of the present invention falls in the opening process, the door body 2 is prevented from being rapidly fallen down and turned over to hurt human bodies or other objects. When the door body 2 needs to be closed, the door body 2 only needs to be lifted slightly by hand, the swing arm 302 swings back to the position in fig. 7, then the hand slightly increases the force for closing the door body 2, so that the driving lug 3021 pushes the push wheel 306 and goes over the push wheel 306, when the driving lug 3021 just swings back to depart from the self-locking position shown in fig. 7, because the force arm of the pushing force of the compression spring 308 to the slide seat rotating shaft 305 is increased, then the compression spring 308 generates the moment for swinging back and resetting to the swing arm 302, so that the door body 2 is closed by itself and attached to the cabinet body 5 through the compression spring 308, and the extension spring 312 also plays a role in assisting in closing the door body 2 in the process.
