This utility model discloses a corrugated cardboard thickness detection device, relating to the field of thickness detection technology. It includes a frame with a horizontal plate fixed on it, and a movable traction assembly mounted on the frame. Two first carrier tubes arranged in parallel are mounted on the movable traction assembly, which drives the two first carrier tubes to move synchronously. A second carrier tube is slidably inserted into the bottom of each first carrier tube, and a U-shaped seat is fixed to the bottom of the second carrier tube. A roller is rotatably connected between the front and rear inner walls of the U-shaped seat via bearings. By turning a knob, a stud can be rotated, causing the stud to pull the carrier plate to slide inside the first carrier tube, thereby adjusting the distance between the bottom of the power supply pin and the top of the power receiving pin. The movable traction assembly pulls the roller to roll above the corrugated cardboard to be tested. Corrugated cardboard with the correct thickness will not trigger the indicator light on the right side to light up, nor will it cause the indicator light on the left side to go out. Corrugated cardboard with a thickness that does not meet the standard will show a different result.

This utility model discloses a block building material inspection device, mainly relating to the field of building material testing. It includes a testing frame with a testing port at its bottom. A thickness measuring ruler is vertically slidably connected inside the testing port. Thickness scale lines are provided at the testing port to cooperate with the thickness measuring ruler. A positioning sleeve is provided on the thickness measuring ruler to cooperate with the testing frame. An angle measuring ruler is rotatably connected to the testing frame above the testing port. An angle scale line is provided on the edge of the testing frame where it intersects with the edge of the rotated angle measuring ruler. A locking pin is provided on the testing frame to cooperate with the angle measuring ruler. The beneficial effects of this utility model are: it can solve the technical problem of inconvenient inspection of processing data for block materials, realizing convenient inspection of the processing thickness and angle of block materials without the need to change different rulers, thus improving the convenience and efficiency of inspection.

This invention discloses BODIPY dyes, their preparation methods, and their applications in latent fingerprint recognition. The invention prepares four BODIPY dyes with different structures and emission colors, all exhibiting high fluorescence quantum yields (over 55% absolute fluorescence quantum yield) and excellent lipophilicity. Using a spray method, latent fingerprints on different substrates can be efficiently and conveniently detected within 10 seconds. Furthermore, the detection solution demonstrates excellent stability, can be stored for up to 30 days, and achieves a color change from green to red through modulation. This modulation effectively addresses complex background colors, ensuring optimal latent fingerprint detection results under various color backgrounds.

This utility model discloses a device for detecting the flatness of terminals after insertion, relating to the technical field of terminal flatness detection equipment. It includes a mounting frame and a mounting base connected within the mounting frame, comprising: at least two support seats fixedly connected to the top of the mounting base; a connecting seat connected to one side of the support seats, arranged in a "Z" shape; and four laser range sensors connected to the connecting seat. In this utility model, by placing the component to be tested on a tray and ensuring its stability, the laser range sensors simultaneously activate and measure the distance values ​​to each corner of the terminal. If the terminal is completely flat after insertion, the distances measured by the four laser range sensors to the four corners of the terminal should be equal or have minimal error. However, if the terminal has flatness deviations, such as a corner being raised or recessed, this setup facilitates efficient detection of the terminal's flatness.
