[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0019] This application discloses a one-stop integrated evidence examination station. (Refer to...) Figures 1-2The system includes a base 1, with anti-slip feet 2 screwed to the corners of the bottom of the base 1. Cylinders 3 are symmetrically installed inside the base 1, and an inspection platform 4 is fixed to the top of each cylinder 3. The base 1 maintains close contact with the ground via the anti-slip feet 2, effectively preventing slippage during inspection due to external forces or operation. An air pump is installed inside the base 1 to drive the cylinders 3 and adjust the height of the inspection platform 4. This allows for flexible adjustment based on the height and operating habits of the inspectors, reducing fatigue during prolonged operation and improving inspection comfort. A set of light-blocking plates 5 are rotatably mounted on the outer wall of the inspection platform 4. A linear motor 8 is installed at the top back of the inspection platform 4, with a matching sliding component internally connected to it. A shadow-removing top light 6 is installed on the sliding component, driven by the linear motor 8. Moving along the back of the inspection platform 4 via the sliding component, the shadow-removing top light 6 provides omnidirectional illumination of evidence at different locations on the inspection platform 4. Whether it is small, minute evidence or large, sheet-like evidence, uniform and sufficient light illumination can be obtained, improving the efficiency and quality of evidence inspection.
[0020] In this application, the outer wall of the shadow-removing top light 6 is equipped with a set of light-blocking plates 2 7. The light-blocking plates 1 5 on the outer wall of the inspection table 4 and 2 7 on the outer wall of the shadow-removing top light 6 can rotate freely, which can adjust the angle and intensity of the light according to the characteristics of the physical evidence and the inspection requirements, avoid interference from ambient light, prevent reflection, shadow and other problems from affecting the observation and shooting of physical evidence details, and ensure the accuracy of the inspection results.
[0021] Reference Figure 3 As shown, a biological sample finder 11 and a photographic bracket 12 are respectively installed on both sides of the back wall of the examination table 4. Electric telescopic rods 9 are installed on both sides of the back wall of the examination table 4, and folding frames 10 are connected to the top of each of the two electric telescopic rods 9. The two folding frames 10 are fixed to the biological sample finder 11 and the photographic bracket 12 respectively with screws. The electric telescopic rods 9 can flexibly adjust the height of the equipment to adapt to the examination angle of evidence of different sizes; the folding frames 10 facilitate the storage and quick deployment of the equipment, saving space when not in use and allowing for rapid deployment when needed, meeting diverse needs for evidence examination and photography.
[0022] In this application, a shrinkage groove is provided on one side of the inner wall of the inspection table 4. An electric telescopic rod 14 is installed on the inner wall of the shrinkage groove. The output end of the electric telescopic rod 14 is connected to a mounting bracket 15. A scale 13 is fixed to the end of the mounting bracket 15. A slide rail 16 is provided inside the scale 13. A matching sliding block 17 is slidably mounted in the slide rail 16. An adjusting ruler 18 is connected to the bottom end of the sliding block 17. The electric telescopic rod 14 pushes the mounting bracket 15 and the scale 13 out of the shrinkage groove, which can be used flexibly according to actual needs. The sliding block 17 slides freely in the slide rail 16 of the scale 13, driving the adjusting ruler 18 to move. The measurement range can be accurately adjusted according to the actual size of the evidence, avoiding the limitations of traditional measuring tools and realizing rapid and accurate measurement of the size of the evidence.
[0023] The implementation principle of the one-stop integrated physical evidence examination station in this application embodiment is as follows:
[0024] In use, the base 1 is securely placed on the work site by anti-slip feet 2 to prevent the equipment from sliding during inspection. According to the needs of evidence inspection, the internal air pump of the base 1 is activated. The air pump adjusts the height of the inspection table 4 via cylinder 3 to suit the operating habits of the inspectors. During evidence inspection, the light-blocking plate 5 on the outer wall of the inspection table 4 and the light-blocking plate 7 on the outer wall of the shadow-removing top light 6 can be rotated to adjust the angle and intensity of the light and avoid light interference. The shadow-removing top light 6 is driven by a linear motor 8 and moves along the back of the inspection table 4 via sliding components to illuminate evidence in different locations.
[0025] The biological sample discovery instrument 11 and the photographing bracket 12 are respectively installed on both sides of the back wall of the inspection table 4 via the electric telescopic rod 9 and the folding frame 10. The photographing equipment can be installed on the photographing bracket 12. The electric telescopic rod 9 can adjust its height. The folding frame 10 facilitates the storage and unfolding of the equipment, meeting the inspection and photographing needs of different types of physical evidence.
[0026] When it is necessary to measure the dimensions of the physical evidence, the electric telescopic rod 14 is activated to push the mounting bracket 15 and the scale 13 out of the shrinkage groove. The sliding block 17 can slide freely in the slide rail 16 of the scale 13, driving the adjusting ruler 18 to move. The measurement range is adjusted according to the actual size of the physical evidence to achieve accurate measurement of the physical evidence. Through the integration and coordination of multiple functions, a one-stop physical evidence inspection work is completed.
