[0031] When manufacturing the bulletproof plug plate, the bullet-facing surface 2, the buffer layer 3, the silicon carbide ceramic layer 4 and the alloy plate 5 are stacked in sequence, and the limiting column 8 is inserted into the connecting hole 7 and fixed, so that the multi-layer structure inside the plug plate body 1 can be tightly matched and formed. At this time, when the internal structure of the plug plate body 1 is damaged by impact, the damaged structural layer can be taken out and replaced separately, which reduces the material loss when the plug plate is used and ensures the versatility of the use of the plug plate.

[0032] Example 2

[0033] Embodiment 2 is based on Embodiment 1 to make the internal multi-layer structure of the plugboard body 1 fit tightly.

[0034] After the limiting column 8 is inserted into the connecting hole 7 inside the plug board body 1, the multiple pressure plates 9 can be rotated and contacted with the outer wall of the plug board body 1, and then the pressure ring 12 is put on the outside of the multiple pressure plates 9 and squeezed.
