The invention relates to the technical field of traffic equipment, and discloses a box body structure and a vacuum sanitary system. The box body structure comprises a front panel, two side plates, a rear panel, a top plate and a bottom plate, the two ends, in the first direction, of the side plates are connected to the front panel and the rear panel correspondingly, the side plates can be folded and stretch out and draw back in the first direction, the upper end and the lower end of the front panel are slidably connected to the top plate and the bottom plate correspondingly in the first direction, a locking device is arranged on the front panel, and the locking device is used for locking the movement of the front panel; when the front panel slides along the top plate and the bottom plate, the front panel drives the side plates to fold and stretch out and draw back so as to adjust the size of a cavity of the box body structure. The size of the box body structure is adjusted, the occupied space of a train or an airplane is saved, and the comfort level of passengers is improved.
