Description

On-spot investigation material evidence box Technical Field The utility model belongs to the technical field of on-site investigation for police, and particularly relates to an on-site investigation material evidence box. Background In the case forensic process, the biological evidence at the crime scene has great value for case forensic. In field investigation, preservation of biological evidence is of paramount importance. It may be a key clue to reveal the true phase of the case, such as bloodstains, hair, etc. Proper preservation can prevent deterioration, pollution or damage of the material evidence, and ensure the authenticity and the integrity of the material evidence. The method not only provides a reliable sample for the subsequent laboratory test, but also is helpful for judicial fairness, so that the true phase can be accurately presented, and the social fairness and legal treatment are maintained. The existing biological material evidence obtained by on-site investigation is commonly stored by adopting a material evidence bag, however, the design has the following problems and defects that 1, the material evidence bag is connected with the material evidence and scratched to cause DNA loss on the material evidence, 2, the material evidence bag is airtight, the DNA is spoiled due to moisture on the material evidence, 3, the material evidence bag is difficult to place and is not standard to store, 4, the material evidence bag is not insulated, and the DNA on the material evidence is easy to spoil due to higher temperature. Therefore, a material evidence box which is convenient for standardized preservation and transfer of biological material evidence in field investigation is needed. Disclosure of utility model The utility model aims to provide an on-site investigation material evidence box which is used for solving the problems in the prior art. The technical scheme includes that the field investigation material evidence box comprises a box body and a box cover, wherein the box cover is clamped on the box body, a material evidence bag, a material evidence buckle and two dehumidification bag placing grids are arranged in the box body, and a plurality of adjacent box bodies are detachably spliced. The lower end face of the box body is provided with tenons at four corners respectively, the four corners of the upper end face of the box cover are provided with mortises, the tenons and the mortises are in one-to-one correspondence fit, the adjacent box bodies can be spliced up and down, and tenons at the lower end of the upper box body are respectively in one-to-one splicing connection with mortises at the upper end of the box cover on the box body adjacent to the lower side.
