A locking pin mechanism for a transport semi-trailer, the locking pin mechanism is used for locking longitudinally extending members of a frame of a transport semi-trailer together with a trailer body movably arranged on the longitudinally extending members. The locking pin mechanism comprises at least two bolt assemblies and a linkage assembly for driving the at least two bolt assemblies. The bolt assembly comprises a bolt, an inner spring, a sliding sleeve, an outer spring and a bracket. The sliding sleeve at an end away from its sliding sleeve end-plate is connected with the linkage assembly; the linkage assembly can be pulled such that the sliding sleeve of the bolt assembly is compresses the inner and outer springs to force the bolt to be pulled out from a locating hole under an action of an elastic force of the inner spring; and after the linkage assembly is released, the bolt can be inserted into the locating hole under the action of the elastic force of the outer spring. The locking pin mechanism of the invention provides an improved operability, an excellent reliability and a convenience in operation.
