The invention relates to a built-in mobile
pallet of a container, comprising a rectangular
chassis with rolling wheels at the bottom, wherein a plurality of guide devices are arranged at two lateral parts and the edge corner parts of the
chassis; the guide devices are of guide wheel structures, and the
peripheral surface of each guide wheel protrudes out of the lateral side of the
chassis; and locking devices are arranged at two corner parts of the rear edge of the chassis. In the invention, the guide wheels are arranged at the lateral parts and the edge corner parts of the chassis, which converts sliding friction with larger resistance into rolling friction with smaller resistance; the
peripheral surface of each guide wheel at the edge corner part is firstly in contact with a firm door frame of the container in the loading process, therefore, the relatively parallel position between the
pallet and the container is well regulated basically; in addition, the guide wheels at the lateral parts can self-adaptively regulate the relative position between the
pallet and the container in the continuous conveying process, thereby preventing the wall of the container from being crashed, even lacerated and effectively protecting the container; and locking hooks arranged at the rear edge corner parts are reasonable in structure, convenient to use and reliable to lock.
