[0014] 2. This testing equipment for the structural strength of metal boxes is equipped with a fixing device, which achieves multiple beneficial effects through its unique design. First, the fixing block fixed to the bottom of the box and the beveled openings on both sides effectively prevent jamming during simulated bumps. Second, the sliding connection between the fixing rod on one side of the box and the inner wall of the sliding groove, combined with the through-hole design, allows the device to be flexibly adjusted according to actual needs, improving ease of use and adaptability. Furthermore, the combination of the second automatic telescopic rod and the second slider, and the linkage between the third automatic telescopic rod and the limiting block, not only achieve precise horizontal positioning of the device, but also effectively restrict the metal box through the L-shaped limiting block design, ensuring the firmness and safety of the fixation.

The design of this impact device, with the cooperation of the second cross rail and the third slider, allows the entire device to move and position flexibly in the horizontal direction, greatly enhancing its ease of operation and applicability. The rotating connection design between the spherical groove and the sphere allows the pneumatic push rod to rotate freely within a certain angle range, thereby adjusting the impact direction of the impact head to meet the impact requirements at different angles.

[0016] 4. This testing equipment for the structural strength of metal boxes is equipped with an installation device. The design of this device, through the cooperation of a fourth automatic telescopic rod and an arc-shaped buckle, enables flexible fixing and release of the impact. This adjustable design allows the equipment to adapt to impact heads of different sizes and shapes, greatly enhancing its versatility and applicability. The fixed connection between the sleeve and the pneumatic push rod ensures that the installation device can work synchronously and stably when the pneumatic push rod is in motion. The sliding connection design between the side of the arc-shaped buckle and the impact head not only ensures the smoothness of the impact head's movement but also reduces energy loss due to friction, improving the equipment's working efficiency.
