Abstract

The invention discloses a concave bulletproof ceramic plate. The concave bulletproof ceramic plate comprises two parallel arch-shaped surfaces, connecting lines of four vertexes of the arch-shaped surfaces form a square, one of the arch-shaped surfaces protruding outwardly is a bullet-ward surface, a square recess is arranged above the bullet-ward surface, a first cambered surface, a plane and a second cambered surface, which are sequentially connected end to end, are arranged on the side wall of the recess from top to bottom, an extension surface of the plane and the bottom surface of the recess form a 135-degree included angle, and the distance between the upper edge of the side wall of the recess and the end of the arch-shaped surfaces is one ninth of the length of the arch-shaped surfaces. The bullet-ward surface of the ceramic plate is provided with the recess, the center of the recess has good bulletproof function for bullets, and the first cambered surface, the plane and the second cambered surface of the side wall of the recess can change applied force direction of the bullets, thus, a bulletproof plate spliced by a plurality of ceramic plates has higher defense capability.

Description

A kind of spill bulletproof ceramic sheet

Technical field

The invention belongs to bulletproof ceramic field, be specifically related to the structure of bulletproof ceramic sheet.

Background technology

Existing bulletproof flashboards is substantially all to have multi-disc bulletproof ceramic sheet to be spliced to form, and every bulletproof ceramic sheet all has good bulletproof function, but has the poor situation of ballistic performance at splicing position.

Summary of the invention

Technical problem to be solved by this invention is: the deficiency existing for prior art, a kind of spill bulletproof ceramic sheet is provided, and strengthen the ballistic performance of each bulletproof ceramic sheet connecting portion, improve the defence capability of bulletproof flashboards.

For realizing the present invention's object, be achieved by the following technical solutions: a kind of spill bulletproof ceramic sheet, potsherd includes two arcuate surfaces that are parallel to each other, the line on four summits of arcuate surface forms a square, in two arcuate surfaces, outwardly one is out surface, out surface top is provided with a foursquare recess, the sidewall of recess is followed successively by end to end the first cambered surface, plane and the second cambered surface from top to bottom, and angle between the elongated surfaces of described plane and recess bottom surface is 135 degree; Described recess sidewall top edge is 1/9 of arcuate surface length to the distance of arcuate surface end.

Compared with prior art, the invention has the beneficial effects as follows: owing to being provided with recess on the out surface of potsherd, there is good bulletproof function recess center to bullet, and the first cambered surface of the sidewall of recess, plane and the second cambered surface play the function that changes bullet force direction, the bulletproof flashboards that has so multiple potsherds to be spliced has stronger defence capability, bullet is penetrated in the time of potsherd recess sidewall, a part of active force of bullet transmits along bulletproof flashboards surface, reduce the frontal impact of bullet to adjacent ceramic sheet link position and caused loosening situation has occurred between potsherd and substrate, ensure good ballistic performance.

Detailed description of the invention

With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.

Shown in Fig. 1 and Fig. 2, a kind of spill bulletproof ceramic sheet described in the present embodiment, potsherd includes two arcuate surfaces that are parallel to each other, the line on four summits of arcuate surface forms a square, in two arcuate surfaces, outwardly one is out surface 1, out surface top is provided with a foursquare recess 2, the sidewall of recess is followed successively by end to end the first cambered surface 3, plane 4 and the second cambered surface 5 from top to bottom, and angle between the elongated surfaces of described plane and recess bottom surface is 135 degree; Described recess sidewall top edge is 1/9 of arcuate surface length to the distance of arcuate surface end.

Claims

1. a spill bulletproof ceramic sheet, it is characterized in that: potsherd includes two arcuate surfaces that are parallel to each other, the line on four summits of arcuate surface forms a square, in two arcuate surfaces, outwardly one is out surface, out surface top is provided with a foursquare recess, the sidewall of recess is followed successively by end to end the first cambered surface, plane and the second cambered surface from top to bottom, and angle between the elongated surfaces of described plane and recess bottom surface is 135 degree; Described recess sidewall top edge is 1/9 of arcuate surface length to the distance of arcuate surface end.
