[0035] Working principle:

[0036] When in use, first assemble the airdrop packaging box 5, then adjust the spacing of the third bracket 21 according to the width of the airdrop packaging box 5, then place the airdrop packaging box 5 on the anti-slip mat 251, rotate and adjust the angle, and then lower the pressing block 231 to press the top cover 54. According to the test needs, replace the measuring pressure head with different shapes, such as a pointed cone type, a flat knife type, etc.;

[0037] When measuring the strength of the steel annular outer frame 51 and the steel base 52, the first screw 142 is manually rotated or driven by a motor to drive the second bracket 14 and the side strength testing device 3 to a specified position. The third screw 31 is manually rotated or driven by a motor to drive the pressure tester 37 forward. The electronic ruler 35 calculates the travel distance. The measuring pressure head contacts the side of the steel annular outer frame 51 or the side of the steel base 52. The pressure tester 37 calculates the pressure and retreats to cancel the test after reaching the specified pressure.

[0038] When measuring the upper and lower sides and four corners of 5, rotate and adjust the angle of the airdrop packaging box 5 and then slide the first bracket 131 to adjust the angle. The edge and corner strength testing component 4 descends and pushes the measuring pressure head to test the force conditions of the upper and lower sides and four corners of the airdrop packaging box 5.
