Description

Technical Field

[0001] This utility model relates to the field of accident evidence collection technology, specifically a paint evidence extractor for traffic accident scenes. Background Technology

[0002] Traffic accident evidence collection is the process of collecting and preserving relevant evidence after an accident to support subsequent legal processing. The collected evidence is systematically organized and properly preserved. In most existing car traffic accidents, the paint will be worn. Paint marks at the collision site are important evidence for determining liability. Therefore, when collecting evidence, the residual paint is usually compared with the paint on the vehicle surface to determine the collision liability.

[0003] However, existing methods for sampling paint from vehicle surfaces typically involve manual scraping by operators before collection. This scraping process requires great care, yet a significant amount of paint still falls off, making it difficult to quickly collect sufficient evidence. To avoid these technical problems, it is indeed necessary to provide a paint evidence extractor for traffic accident scenes to overcome the aforementioned deficiencies in the existing technology. Utility Model Content

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-4 As shown, this utility model provides a technical solution: a paint evidence extractor for traffic accident scenes, including an installation cylinder 1, with a sampling component 2 installed inside the installation cylinder 1;

[0030] The sampling assembly 2 includes a scraper 201, a brush 202, a suction tank 203, a fixing ring 204, a cone 205, a magnet 206, a connecting cylinder 207, a bottom fine filter 208, a motor frame 209, an exhaust fan 210, and a top filter 211;

[0031] A scraper 201 is welded to the bottom end of the mounting cylinder 1. Several scrapers 201 are provided and are welded at equal intervals at the bottom of the mounting cylinder 1 to facilitate scraping the paint. A brush 202 is attached to the bottom end of the mounting cylinder 1. A suction groove 203 is opened at the middle of the bottom end of the mounting cylinder 1. A fixing ring 204 is embedded in the inner side of the mounting cylinder 1. A cone 205 is welded to the top of the fixing ring 204. A magnet 206 is attracted to the top of the mounting cylinder 1. The outer diameter of the fixing ring 204 is equal to the inner diameter of the mounting cylinder 1. The outer diameter of the magnet 206 is equal to the outer diameter of the mounting cylinder 1, which is conducive to quick disassembly. A connecting cylinder 207 is installed on the top of the magnet 206.

[0032] A bottom fine filter screen 208 is installed at the bottom of the connecting cylinder 207. A motor frame 209 is welded to the inside of the connecting cylinder 207. An exhaust fan 210 is installed on the inside of the motor frame 209. An installation groove is opened at the corresponding position of the exhaust fan 210 on the inside of the motor frame 209. The input end of the exhaust fan 210 is electrically connected to the output end of the internal battery pack for convenient and rapid sampling. A top filter screen 211 is installed at the top of the connecting cylinder 207.

[0033] A storage component 3 is installed on the outside of the mounting cylinder 1;

[0034] Storage component 3 includes a snap-fit ​​slot plate 301, a fixing plate 302, a placement chamber 303, a sponge 304, a protective slot plate 305, and an anti-slip rubber 306;

[0035] A snap-fit ​​groove plate 301 is welded to the outer side of the mounting cylinder 1, and a fixing plate 302 is welded to the inner side of the snap-fit ​​groove plate 301. A placement chamber 303 is formed between the fixing plate 302 and the snap-fit ​​groove plate 301. A sponge 304 is snapped into the inner side of the placement chamber 303. A protective groove plate 305 is snapped into the outer side of the snap-fit ​​groove plate 301. A limiting groove is opened on the back of the protective groove plate 305 at the corresponding position of the snap-fit ​​groove plate 301. The protective groove plate 305 is snapped into the outer side of the snap-fit ​​groove plate 301 through the limiting groove, which is conducive to the quick removal of the sponge 304. Anti-slip rubber 306 is bonded to the front end face of the protective groove plate 305.

[0036] The working principle and usage process of this utility model are as follows: First, when taking samples, the operator determines whether the paint to be sampled is liquid or solidified. If it is solid paint, the scraper 201 can be moved to the solid paint area. The scraper 201 can then scrape the paint to remove it from the sampling area. If it is paint on the ground, after scraping off the paint, the brush 202 is used to collect the paint. Then, the exhaust fan 210 is turned on, and the suction tank 203 is aligned with the paint. The paint will then be drawn into the cone 205. At the top, tilt the mounting cylinder 1 and turn off the exhaust fan 210. At this time, the paint blocked by the bottom fine filter 208 will fall to the top of the fixing ring 204. At this time, the connecting cylinder 207 can be pulled off from the top of the mounting cylinder 1. At this time, the paint sample can be recovered. If the paint is suspended and attached to other items, the exhaust fan 210 can be turned on while scraping. At this time, the material can be collected quickly while scraping. It is simple and convenient to use, simplifying the sampling steps, and can quickly and sufficiently continue to collect the material, ensuring the accuracy of the comparison.

[0037] Finally, if the collected substance is liquid paint, the operator can remove the protective tray 305 from the surface of the snap-fit ​​tray 301, and then move the sponge 304 to the liquid paint. The sponge 304 can then absorb the paint. After absorption, the protective tray 305 can be placed over the outside of the snap-fit ​​tray 301 to protect the paint and prevent it from being contaminated. The sampling device can then be placed on the table using the protective tray 305. The anti-slip rubber 306 can prevent the mounting cylinder 1 from moving and falling. During testing, the sponge 304 can be removed from the inside of the placement chamber 303, and the paint can be squeezed out for rapid comparison, further improving the applicability of the device.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
