Locking assembly modular pallet

A locking assembly modular pallet, characterized in that: an insertion block (21) comprises a main body (211) provided with a locking hook (212) on at least one side portion of an insertion groove (11) in a width direction thereof. The upper end of the locking hook (212) is rotatably engaged with the main body (211) to form a pivot, and a hook portion (2121) provided at an outer side of the lower end engages with a catching portion (111) of the insertion groove (11). A temporary positioning inclined surface (113) is provided at the bottom of the insertion groove (11) corresponding to an inner side of a base portion of the locking hook (212). When the insertion block (21) is inserted into the groove (11), an inner side of the locking hook (212) slidably engages with the temporary positioning inclined surface (113), causing the locking hook (212) to rotate outwards, such that the hook portion (2121) thereof engages with the catching portion (111) of the insertion groove (11), thereby forming a temporary positioning structure for the insertion block (21). The pallet can be mounted on a support beam from a vertical direction while maintaining a high reliability of connection between the pallet and the supporting beam, addressing the difficulty of replacing the central part of a pallet.
