This invention relates to a model buffer and capture device for land-based vertical catapult tests. The device, used to capture a model, includes a damping system and a capture system. The damping system absorbs energy and buffers during the capture process. The capture system, mounted on the damping system, includes a capture support with a buffer net at its top and a gripper system below the net for clamping and securing the model. A photoelectric proximity switch is also mounted on the capture support; when the switch detects an object passing through, it sends an electrical signal to control the gripper system. A launch tube, vertically positioned below the capture system, launches the model. This invention enables capture in vertical land-based catapult tests, allowing for safe, damage-free, and efficient model recovery after launch, thus improving test efficiency. The buffer system significantly reduces the load on the grippers during model capture, enhancing the overall system reliability.

The invention relates to the technical field of curved surface touch display screen testing, in particular to a strength testing device for curved surface touch display screen production. The invention provides an intensity test device for curved surface touch display screen production, which comprises a drop test machine, symmetrically distributed electric slide rails are installed in the drop test machine, a slide piece is slidably connected between the symmetrically distributed electric slide rails, and a slide switch is slidably connected to one side, close to the electric slide rails, in the drop test machine. A buffer spring is connected between the slide switch and the drop test machine. The angle of the test piece can be adjusted through cooperation of the first screw sleeve, the moving piece and the second screw sleeve, so that the comprehensiveness and accuracy of the test result are ensured, the ground made of different materials is selected by rotating the rotating shaft to adapt to various test environments, the flexibility is further improved, the rope winding wheel and the pull rope work cooperatively, and the test efficiency is improved. Convenience is provided for repeated testing, and the testing efficiency is improved.
