Graphite protective plate structure

The utility model discloses a graphite protective plate structure, including the backplate body, set up the multiseriate pilot hole on the backplate body for with not unidimensional crucible assembly. Graphite protective plate structure is through setting up the multiseriate pilot hole at the backplate body for graphite protective plate can be through the crucible assembly that is listed as pilot hole and different models of difference row, and same graphite protective plate can satisfy the assembly of the crucible of different models promptly, saves the cost, when graphite protective plate assemble, can save because the crucible with to protect board ruler cun selection consuming time, the improvement productivity. 本实用新型公开了种石墨护板结构，包括护板本体，所述护板本体上设置多列装配孔，用于与不同尺寸的坩埚装配。所述石墨护板结构，通过在护板本体设置多列装配孔，使得石墨护板可以通过不同列的列装配孔与不同型号的坩埚装配，即同石墨护板可以满足不同型号的坩埚的装配，节省成本，在石墨护板装配时，可以省去因为坩埚与护板尺寸选择耗时，提高产能。
