Flat plastic molding board
The invention provides a flat plastic molding board. The flat plastic molding board is structured by comprising a panel, a side frame vertical to the panel, a plurality of connecting holes which are uniformly formed in the side frame, back rib plates which are vertically arranged on the back surface of the panel, reinforcing ribs which are arranged on the front surface of the panel and are in one-to-one correspondence with the back rib plates and a row of bolt holes which are spaced in joints of the back rib plates. The bolt holes comprise circular holes penetrating through the panel and an convex ring which is arranged on the back surface of the panel along the circular holes, wherein two axial guide slots are symmetrically formed in the inner wall of the ring with respect to the central axis for dividing the inner wall into two same areas; a spiral clamping slot which is gradually reduced is formed in each area, relatively wide end of the spiral clamping slot is communicated with the end part of the guide slot, the relatively narrow end of the spiral clamping slot and the other guide slot extend, the slot bottom of the spiral clamping slot is a continuously step-shaped clamping table, and a ring slot is formed in the front surface of the panel along the peripheries of the circular holes. The flat plastic molding board solves the problem that an existing plastic molding board is not tightly sealed in bolt holes and is easy to break a using process.
