This utility model discloses a protective structure for police bulletproof vests, including a storage cabinet. The storage cabinet has a door on one side, a splicing mechanism for easy assembly on the outside, and a drying mechanism for easy drying of the interior at the lower end. A first support plate is fixedly installed inside the storage cabinet, and a second support plate is welded and fixed inside the cabinet. The door is magnetically attached to one side of the storage cabinet. In use, the bulletproof vest is placed inside the storage cabinet, with one side resting on the first support plate and the other side on the second support plate. This prevents the vest from being squeezed from both sides and eliminates the need for hanging, thus facilitating the protection of the bulletproof vest.

A collapsible ballistic body armor system having a linear arrangement of two to four armor panels in a deployment condition defining a rectangular prism array of armor panels shielding the front of the user. Each adjacent armor panel is interconnected along their respective edges by a hinge connection so that the collapsible ballistic body armor system is movable between the deployment condition and a folded position. In the deployment condition, a cover panel pivotably attached to each armor panel pivots to cover a gap between each adjacent armor panel. The system provides a neck strap from which initial deployment may be achieved under the urging of gravity.

A wearable energy absorbing and dispersing standoff spacer, system, and method for use or incorporation with an armor plate or panel, and / or a carrier for the same, uses one or more spacer panels having features that interlock to form a stack having a desired standoff thickness and resilient compressibility for absorbing and dispersing forces exerted thereagainst from ballistic impacts to reduce traumatic effect on a wearer while limiting lateral displacement of the spacer particularly under lateral forces, and that is readily and easily adaptable to provide customizable support, positioning, and orientation for the armor plate or panel, and fit and comfort for the wearer, particularly female wearers.

This invention relates to the field of personal protective equipment materials technology, and in particular to an ultralight bulletproof fabric and its preparation method. The bulletproof fabric is composed of a protective outer layer and an anti-deformation inner layer, which are composited with thermoplastic resin. The protective outer layer is made of UHMWPE fiber with a linear density variation coefficient (CV) of <3% to form a non-woven fabric, which mainly absorbs impact energy efficiently. The anti-deformation inner layer is made of widened UHMWPE fiber non-woven fabric with a width of 6~10mm to effectively suppress back deformation. This structure achieves high bulletproof performance, low back protrusion, and good flexibility at an ultra-low areal density of 3.0~6.0kg / m², making it suitable for a new generation of high-performance soft bulletproof vests.

The present application relates to the technical field of ceramic sheet processing, and discloses a ceramic sheet forming device and a production method for an alumina insert plate of a bulletproof vest, which comprises a steel frame, a pressing mechanism, a fixed mold and a lower mold arranged on the steel frame from top to bottom, a plurality of pressing holes and a blanking port formed in the fixed mold, a mold closing hydraulic cylinder arranged on the steel frame, an electric push rod and a cleaning mechanism arranged on the fixed mold, the cleaning mechanism comprising a plurality of air blowing nozzles, a plurality of spraying nozzles, a driving member and a push plate, and a material returning mechanism arranged on the steel frame, the material returning mechanism comprising a scraper, a pushing member and a mesh screen. The present application can clean the inner wall of the pressing hole, automatically return the ceramic sheet, greatly improve the use convenience, recycle the excess dry powder, conveniently demold the formed ceramic sheet, and further improve the use convenience.

This invention discloses a composite self-healing bulletproof material system based on rare earth catalysis and a dynamic covalent network, belonging to the field of intelligent protective equipment technology. The system is based on Ce... 3+ -ATSP Surface Repair Module and Gd 3+ The -2DPA-1 deep repair module works in synergy, employing a graded strategy of rapid surface repair and deep structural reconstruction to achieve a repair rate of ≥85% for scratches ≤2mm within 25 minutes and a repair rate of ≥78% for dents ≤5mm within 90 minutes. It innovatively proposes a quantitative coupling model between repair efficiency and impact energy absorption, and constructs a three-tiered repair network of surface-transition-deep layers. Integrated into the inner liner of a bulletproof vest, the system maintains a performance retention rate of ≥95% after 5 impact-repair cycles. This invention represents the first intelligent leap in bulletproof materials from "passive protection" to "active diagnosis-graded repair-functional retention," significantly enhancing the battlefield survivability of individual soldiers' equipment.

Described herein is a body armor plate carrier in the form of a tactical vest. The body armor plate earner includes a front panel, a rear panel, a pair of side panels, shoulder straps and a cummerbund element. The side panels are provided to offer protection to the breast area of the female wearer's anatomy. The shoulder straps are V-shaped racerback straps, which effectively distribute the weight of the body armor plate carrier and thereby relieve the pressure imposed upon the neck, shoulders, and upper back, while also providing improved back support. The cummerbund element fits around the waist of the wearer, thereby providing a secure fit of the body armor plate carrier to the anatomy of the wearer.

This invention belongs to the field of impact protection technology and relates to a double-layer thin-walled impact-resistant protective structure composed of triangular pyramidal units. This structure consists of multiple bottomless triangular pyramidal units that are alternately assembled to form a strip-like structure, which is then connected end-to-end to form a cylindrical double-layer thin-walled structure. The geometric dimensions are determined by the number of triangular pyramidal units used, which must be even and no less than six. This structure utilizes the low out-of-plane buckling stiffness of the oblique triangular facets to form a stable progressive deformation mode during axial crushing, thereby achieving high specific energy absorption capacity and low initial peak load. This structure, arranged in an array, serves as the core layer and is combined with a polyethylene non-woven fabric panel to form a "sandwich" composite protective structure. It can be used in protective equipment such as individual body armor, providing comprehensive protection against both ballistic and blunt force trauma, effectively reducing blunt force trauma damage caused by projectile impacts.
