Description

Technical Field

[0001] This utility model belongs to the field of police crime scene investigation technology, and in particular relates to a crime scene investigation evidence box. Background Technology

[0002] In the process of solving cases, biological evidence at crime scenes is of great value. The preservation of biological evidence is crucial during crime scene investigation. It may be a key clue to uncovering the truth of the case, such as bloodstains or hair. Proper preservation can prevent the evidence from deteriorating, becoming contaminated, or being damaged, ensuring its authenticity and integrity. This not only provides reliable samples for subsequent laboratory testing but also contributes to judicial fairness, allowing the truth to be accurately presented and upholding social justice and the rule of law. Currently, biological evidence obtained from crime scenes is generally preserved in evidence bags. However, regardless of the type of evidence bag used, these designs have the following problems and drawbacks: 1. The evidence bag may come into contact with or scratch the evidence, causing DNA loss; 2. The evidence bag is not breathable, and moisture on the evidence can lead to DNA decay; 3. The evidence bag is difficult to place, resulting in non-standard preservation of the evidence; 4. The evidence bag is not heat-insulated, and higher temperatures make the DNA on the evidence more susceptible to decay. Therefore, there is a need for an evidence box that facilitates the standardized preservation and transfer of biological evidence during crime scene investigations. Utility Model Content

[0003] The purpose of this invention is to provide a crime scene investigation evidence box to solve the aforementioned problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A crime scene investigation evidence box includes a box body and a box lid. The box lid is snapped onto the box body. The box body contains an evidence bag, an evidence buckle, and two dehumidifying bag compartments. Multiple adjacent boxes can be detachably spliced ​​together. Tenons are provided at the four corners of the lower end face of the box body, and tenons are provided at the four corners of the upper end face of the box lid. The tenons and tenons are matched one-to-one. Adjacent boxes can be detachably spliced ​​vertically. The tenons at the lower end of the upper box body are respectively inserted into the tenons at the upper end of the box lid of the adjacent lower box body. A dovetail block is provided on the left end face of the box body, and a dovetail groove is provided on the right end face. Adjacent boxes can be detachably spliced ​​horizontally. The dovetail groove on the right end of the left box body is spliced ​​with the dovetail block on the right adjacent box body.

[0005] Furthermore, the box body is provided with a dehumidifying bag placement compartment, which can be set on the side wall or four corners of the box body. A dehumidifying bag is placed in the dehumidifying bag placement compartment, and several through holes are provided on the side wall of the dehumidifying bag placement compartment.

[0006] Furthermore, the evidence buckle is set on the inner side wall of the box, and the evidence bag is provided with ventilation holes and is suspended and clamped in the box by the evidence buckle. The evidence buckle is a spring buckle.

[0007] Furthermore, an insulation layer is provided on the inner side wall of the box.

[0008] Furthermore, a photo slot is provided on the front side of the box.

[0009] Furthermore, a coded label is provided on the front face of the box.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model features a multifunctional design. The evidence box not only has basic evidence storage functions, but also incorporates dehumidifying compartments, evidence clips, and insulation layers. It effectively protects evidence from factors such as moisture and temperature changes, while facilitating the fixation and positioning of evidence to ensure its integrity and accuracy. It also reduces contact between evidence and unrelated items, minimizing DNA loss. Furthermore, it removes moisture from the evidence, preventing DNA decay, and provides environmental conditions suitable for the preservation of various types of evidence.

[0012] 2. The present invention features a modular design, in which multiple boxes can be detachably joined vertically or horizontally through the cooperation of tenons and mortises, dovetail blocks and dovetail grooves, which facilitates flexible combination according to actual needs and improves the convenience of carrying and organizing.

[0013] 3. This utility model has a good effect on securing physical evidence. The unique structural design of the physical evidence buckle, combined with the elastic protrusion and sponge block, can firmly hold the physical evidence bag and prevent the physical evidence from being collided and shifted during transportation.

[0014] 4. This utility model facilitates information recording. The setting of photo slots and coded labels enables the labeling and unified management of physical evidence, making it convenient for taking photos for archiving and investigation analysis, and facilitating the recording of relevant information about physical evidence for management and retrieval.

[0015] 5. This utility model can be used multiple times, reducing resource waste and saving costs. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0024] Detailed implementation methods: such as Figures 1-5 As shown, this embodiment discloses a crime scene investigation evidence box, including a box body 1 and a box lid 2. The box lid 2 is snapped onto the box body 1. The box body 1 contains an evidence bag, an evidence buckle 7, and two dehumidifying bag storage compartments 8. Multiple adjacent box bodies 1 are detachably connected. Tenons 5 are provided at the four corners of the lower end face of the box body 1, and tenons 6 are provided at the four corners of the upper end face of the box lid 2. The tenons 5 and tenons 6 are matched one-to-one. Adjacent box bodies 1 are detachably connected vertically. The tenons 5 at the lower end of the upper box body 1 are respectively inserted into the tenons 6 at the upper end of the box lid 2 of the adjacent lower box body 1. A dovetail block 3 is provided on the left end face of the box body 1, and a dovetail groove 4 is provided on the right end face of the box body 1. Adjacent box bodies 1 are detachably connected horizontally. The dovetail groove 4 on the right end of the left box body 1 is connected to the dovetail block 3 on the right adjacent box body 1.

[0025] Furthermore, the box body 1 is provided with a dehumidifying bag placement compartment 8, which can be set on the side wall or four corners of the box body 1. A dehumidifying bag is placed in the dehumidifying bag placement compartment 8, and several through holes are provided on the side wall of the dehumidifying bag placement compartment 8.
