Description

Technical Field

[0001] This utility model relates to the field of customs hazardous chemicals supervision technology, specifically a customs hazardous chemicals accompanying document comparison terminal. Background Technology

[0002] In customs hazardous chemicals supervision scenarios, handheld document comparison terminals are the core equipment for on-site verification and rapid customs clearance. They need to operate frequently in complex environments such as port inspection areas, container yards, and enterprise warehouses, and are responsible for collecting and comparing information such as Safety Data Sheets (SDS), hazard disclosure labels, and declarations of conformity.

[0003] Currently, most handheld terminal scanning cameras adopt a fixed, exposed design. When the handheld terminal is not in use, whether it is placed in the pocket of an inspection vest, a storage bag, or temporarily placed on the inspection table, the exposed camera lens is easily scratched. Over time, the lens will accumulate more and more scratches, causing blurry image acquisition and affecting the accuracy of subsequent document comparison. Therefore, a customs dangerous chemicals accompanying document comparison terminal is needed. Utility Model Content

[0004] The purpose of this invention is to provide a customs dangerous chemicals accompanying document comparison terminal, which solves the problems mentioned in the background art.

[0005] This application provides a customs dangerous chemicals accompanying document comparison terminal, including a terminal body. A damping shaft is fixedly connected to one outer wall of the terminal body. A scanning camera is fixedly connected to the rotating end of the damping shaft. A slot is opened on the outer wall of the terminal body on the same side as the damping shaft. The slot is located below the damping shaft. A guide rod is fixedly connected inside the slot. A slider is slidably mounted on the guide rod. An adjusting block is spirally mounted on the outside of the guide rod. The adjusting block is supported at the bottom end of the slider. A protective shell is fixedly connected to the side of the slider away from the terminal body.

[0006] In use, the scanning camera scans paper documents. The information acquisition module converts the physical information of the paper documents into electronic images or data. The data processing module receives information from the information acquisition module and completes the core calculations of image preprocessing, data extraction, and rule comparison. The communication transmission module enables data interaction between the customs back-end system and the terminal itself, obtaining the benchmark data required for comparison. The comparison results are displayed on the screen for quick comparison and judgment by relevant personnel. When the terminal is not in use, the scanning camera is flipped over by rotating the damping shaft until the lens faces downward. Then, the slider is slid on the guide rod, which moves the protective shell upward until the scanning camera is inside the protective shell. Then, the adjustment block is manually rotated to support the bottom of the slider, preventing the slider from sliding down. This effectively protects the scanning camera from scratches on the lens, which could cause blurry image acquisition and affect the accuracy of subsequent document comparison.

[0007] Optionally, a display screen is embedded in the front wall of the terminal body, and an information acquisition module, a data processing module, a communication transmission module, a security protection module, and a power supply module are arranged sequentially from left to right inside the terminal body. The display screen, information acquisition module, data processing module, communication transmission module, and security protection module are all electrically connected to the power supply module through power supply wires.

[0008] By adopting the above technical solution, the information collection module can convert the physical information of paper documents into electronic images or data. The data processing module receives the information from the information collection module and completes the core calculations of image preprocessing, data extraction and rule comparison. The communication transmission module realizes the data interaction between the customs back-end system and the terminal body, obtains the benchmark data required for comparison, and displays the comparison results on the display screen to facilitate quick judgment by relevant personnel. In addition, the security protection module can ensure that the data is not leaked.

[0009] Optionally, a heat dissipation vent is provided on the rear wall of the terminal body, and a dustproof mesh is fitted inside the heat dissipation vent.

[0010] By adopting the above technical solution, the heat dissipation vents can be used to dissipate heat from the internal components of the terminal body, and the dustproof mesh can prevent dust from entering the interior of the terminal body.

[0011] Optionally, the top of the protective shell is provided with a storage slot, the length and width of which are adapted to the length and width of the scanning camera, and a rubber pad is glued and fixed inside the protective shell.

[0012] By adopting the above technical solution, the scanning camera can be fitted into the interior of the protective shell, improving the protective effect. Furthermore, the rubber pad increases the flexible connection between the protective shell and the scanning camera lens, further enhancing the protection of the scanning camera.

[0013] Optionally, a handle is fixedly connected to one side of the bottom of the terminal body.

[0014] By adopting the above technical solution, the handle makes it easier for staff to hand-hold the terminal.

[0015] Optionally, the protective shell is made of plastic.

[0016] By adopting the above technical solutions, it is beneficial to reduce the weight of the protective shell.

[0017] Optionally, the display screen is a touch screen.

[0018] By adopting the above technical solutions, it is beneficial to improve the ease of operation for staff.

[0019] Optionally, the outer wall of the adjusting block is provided with anti-slip texture.

[0020] By adopting the above technical solution, it is easier for operators to avoid slipping when adjusting the adjustment block.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application enables the installation of the guide rod through the slot. When the terminal body is not in use, the scanning camera is flipped over by the damping shaft so that the lens of the scanning camera faces downward. Then, the slider slides on the guide rod, thereby moving the protective shell upward until the scanning camera is inside the protective shell. Then, the adjustment block is manually rotated to support the bottom of the slider and prevent the slider from sliding down. Through the coordination of the above structures, the scanning camera can be effectively protected to avoid scratching the lens, so as to avoid blurry image acquisition and affect the accuracy of subsequent document comparison.
