[0002] The current method for testing the protective effectiveness of bomb disposal suits is to place a simulated dummy in the test area, wear an explosion-proof suit on it, detonate the explosives placed around it, and after the explosion, judge the protective effectiveness of the bomb disposal suit by observing the integrity of the suit and the degree of damage to the simulated dummy.

[0003] However, due to the different postures of the simulated dummies, some tests use simulated dummies in standing, half-squatting, squatting and other postures to test the protective effectiveness of the bomb disposal suit. The same bomb disposal suit will have a large difference in the degree of damage if different postures are used during testing. This leads to different protective effectiveness of the bomb disposal suit obtained from the test. Moreover, when the bomb disposal suit is impacted during the explosion, the dummy wearing the bomb disposal suit will fall over, resulting in incomplete impact test of the explosion and inability to fully judge the protective effectiveness of the bomb disposal suit. In order to solve the above problems, this application proposes a bomb disposal suit protective effectiveness testing device. Utility Model Content
