Bullet-proof helmet testing device

Abstract

The invention discloses a bullet-proof helmet testing device which comprises a body, wherein a cavity is formed in the body; a pressure block is arranged in the cavity; a pressure bar is fixedly arranged on the upper end face of the pressure block; the pressure bar is fixedly connected with a pressure-resistant testing device; a moving cavity is formed in the lower side of the cavity; a fixing block is arranged in the moving cavity; a clamping cavity which has an upward opening and is communicated with the cavity is formed in the fixing block; shrinking slots with opposite openings are formedin the clamping cavity in a bilateral symmetry manner; a clamping plate is arranged in the shrinking slots; and a rubber pad is fixedly arranged on one end face, which is close to the clamping cavity,of the clamping plate. During operation, the bullet-proof helmet is subjected to high-voltage insulation test and gravity impact test by a driving conversion device, the energy consumption is low, and the linkage property is high. Due to locking of a bracing wire at the upper end of a gravity block and setting of a sliding plate, the impact experiment safety is improved, the high-voltage insulation test and impact test can be fully automatically performed, and the detection accuracy is improved.

Description

Technical field [0001] The invention relates to the field of material testing, in particular to a bulletproof helmet testing device. Background technique [0002] As the main equipment of warfighters, bulletproof helmets can protect warfighters from injury or reduce the degree of injury. Therefore, it is particularly important for the quality and structure of bulletproof helmets, mainly for pressure test and gravity impact test. The current bulletproof helmet tests mainly It is through the impact of live ammunition to conduct penetration testing and bulletproof testing of the helmet material, but for general performance testing, direct use of ammunition will cause waste, and it cannot be applied to basic performance testing. The initial data value of the laboratory is measured, and the current testing device protects The measures are low and unsafe accidents are easily caused. At the same time, the material performance data of the bulletproof helmet cannot be detected in real tim...

[0002] As the main equipment of combatants, bulletproof helmets can protect combatants from injury or reduce the degree of injury. Therefore, the quality and structure inspection of bulletproof helmets is particularly important, mainly for pressure resistance tests and gravity impact tests. The current bulletproof helmet tests are mainly The penetration test and bulletproof test are carried out on the helmet material through the impact of live ammunition, but direct use of ammunition for general performance testing will cause waste, and it cannot be applied to basic performance testing. Measures are low, it is easy to cause unsafe accidents, and the material performance data of bulletproof helmets cannot be detected in real time at the same time. This device of the present invention can solve this problem
