A passenger boarding bridge leveling mechanism mounted on a passenger boarding bridge includes a four-bar linkage mechanism and a preload apparatus. The four-bar linkage mechanism includes a mounting base which can be fixedly mounted on the passenger boarding bridge. One of the other three bars of the four-bar linkage mechanism extends outwards, and a leveling wheel and a first detection switch are mounted on the end of the bar. The first detection switch is used for detecting the vertical displacement of the leveling wheel on an aircraft fuselage. The preload apparatus has a preload force. One end of the preload apparatus is connected to the four-bar linkage mechanism, and the other end is connected to the mounting base. The preload apparatus has a preload force to make the leveling wheel maintain a tendency of extending outwards. The passenger boarding bridge leveling mechanism has high test precision and can work reliably.
