In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the present application, unless expressly stated or limited otherwise, the first feature may be directly on or directly under the second feature or indirectly via intermediate members. Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Referring to fig. 1-5, a novel bulletproof insert plate is shown, which comprises an alloy protection plate 1 and a ceramic plate 2, wherein a cavity is formed in the alloy protection plate 1, the ceramic plate 2 is arranged in the cavity, and the alloy protection plate 1 tightly wraps the ceramic plate 2; the inner side surface of the alloy guard plate 1 is concavely provided with a plurality of heat dissipation grooves 11.

Thus, the bulletproof flashboard is a composite protection structure formed by the alloy guard plate 1 and the ceramic plate 2, wherein the ceramic plate 2 is tightly wrapped by the alloy guard plate 1, so that the structural stability can be ensured under any severe environment, and the sufficient stability of the protection performance is ensured; in addition, the heat dissipation groove 11 is formed in the inner side face of the alloy protection plate 1, so that heat dissipation and sweat discharging of a human body are facilitated, skin itching and inflammation are avoided, and long-time latent combat of soldiers is facilitated. In addition, when a bullet hits the bulletproof inserting plate, the bullet is blocked by one surface of the alloy protecting plate 1, partial kinetic energy is lost even if the bullet passes through the bulletproof inserting plate, the bullet impacts the ceramic plate 2, the ceramic plate 2 absorbs the kinetic energy of the bullet to be broken and can transmit huge impact energy of an impact point to the periphery, the alloy protecting plate 1 tightly wrapping the ceramic plate 2 can play a role in restraining to prevent cracks on the ceramic layer from expanding, the impact energy on the ceramic plate 2 can also be transmitted to the alloy protecting plate 1, and the metal plasticity of the alloy protecting plate 1 can remove the impact energy; finally the bullet is stopped.
