Description

Technical Field

[0001] The utility model relates to the technical field of bulletproof ceramic processing, in particular to a fastening clamp for bonding bulletproof ceramics. Background Art

[0002] Bulletproof ceramics absorb the kinetic energy of projectiles due to their rupture. Ceramic armor systems are composed of a single piece of ceramic or a ceramic-metal composite covered with a nylon cloth layer combined with high tensile strength organic fibers.

This may result in uneven pressure applied to the ceramic block, causing an uneven surface of the spliced ​​ceramic blocks, thus affecting the quality and performance of the final product. Therefore, there is a problem of being inconvenient to apply pressure to the upper surface of the ceramic block. Utility Model Content
