This invention discloses a test device and method for the impact performance of an engine conical wall structure, belonging to the technical field of aero-engine structural strength testing. The device includes: a hammer for generating a falling impact; a transition assembly for an interference fit connection with the front end of the conical wall structure; a bracket for a fixed connection with the rear end of the conical wall structure; a protective assembly positioned along the hammer's descent path and on the side of the conical wall structure to catch the hammer after the conical wall structure fractures; and a protective box positioned directly below the conical wall structure to receive the failed falling conical wall structure. The method includes static load calibration and dynamic impact testing steps. This invention can meet the requirements for both split and integrated installation of conical wall structures, achieving a stable connection and dual safety protection under high-energy impacts. It can simultaneously complete static load calibration and dynamic impact integrated testing, ensuring safe and reliable testing.

This utility model discloses a contactless card reader, relating to the field of IC card reader technology. It includes a card reader body with a guide recess at the bottom of the front side. The guide recess has a U-shaped structure with an open bottom. A card reader mark is provided on the inner wall of the guide recess, aligning with the coil position inside the card reader body. A fluorescent light strip surrounds the side wall of the guide recess. This application provides a contactless card reader. The U-shaped guide recess with an open bottom on the front of the card reader body serves as a foolproof feature to prevent users from missing their IC cards. Furthermore, the card reader mark on the inner wall of the guide recess aligns with the coil position inside the card reader body, physically guiding the user to accurately position and align the card reader with the coil for contactless reading, improving the success rate. Additionally, the fluorescent light strip surrounding the side wall of the guide recess provides guidance for users at night, making it highly practical.
