Plastic partition plate

The utility model relates to a plastic separating plate comprising two parallel plate bodies, between which a plurality of strengthening ribs are arranged. The utility model is characterized in that the strengthening ribs in long strip shape are in continuous and bending arrangement between the two plate bodies which are in flat shape, and every strengthening rib comprises two arc surfaces and two parallel planes which are connected to the plate bodies. When the plastic separating plate is under external force in any direction, the external force can be dispersed by the strengthen ribs, therefore, the plastic separating plates are hard to bend and deform and has good practicality.
