Description

Technical Field

[0001] The utility model relates to the technical field of fire investigation, in particular to a classified evidence collection box for fire investigation. Background Art

[0002] After extinguishing the fire, firefighters must quickly investigate the cause of the accident. The extraction of physical evidence must be scientifically and technically guaranteed to ensure the timeliness and legality of the extraction. The principles of objectivity and fairness must be followed in obtaining evidence. Instead of trusting one's own subjective will and not believing the facts shown by the evidence, the principles of fairness and justice can objectively and impartially reflect the work process. The extraction of physical evidence during fire investigations should collect as much physical evidence as possible while ensuring the quality of the evidence. Through relevant analysis of the evidence, the logical relationship between the previous and the next evidence should be found to determine whether the case itself is true, and then the cause of the accident should be found out, the nature of the accident should be clarified, and the responsibility for the accident should be clarified.

[0003] At present, fire evidence collection is done manually and then put into evidence bags, but most evidence bags do not have a unified classification and storage method. The most common ones are scattered in boxes. Evidence collectors need to attach scene photos after collecting evidence, but the messy evidence bags are inconvenient to take. Moreover, due to the different sizes of evidence, smaller boxes cannot accommodate them, and larger boxes are prone to cause evidence to collide with the box wall during transportation and suffer secondary damage, which makes it difficult to analyze the later evidence. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that most evidence bags in the prior art have no unified classification and storage method, and are more commonly placed in a box in a scattered manner.

In addition, due to the different sizes of evidence, smaller boxes cannot accommodate them, and larger boxes are prone to cause the evidence to collide with the box wall during transportation and be secondary damaged, which makes it difficult to analyze the evidence later. The utility model provides a classified evidence collection box for fire investigation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a classification evidence collection box for fire investigation, comprising an evidence collection box body, the outer surface of the evidence collection box body is fixedly connected to a baffle, the outer surface of the baffle is connected to a box body, the outer surface of the box body is fixedly connected to a hinge, the outer surface of the baffle is fixedly connected to a handle, the inner wall of the box body is provided with an evidence storage groove, the inner wall of the box body is provided with a placement groove, a slide rod is fixedly installed on the inner wall of the evidence storage groove, the outer surface of the slide rod is sleeved with a spring, one end of the spring is fixedly connected to a splint, and the inner wall of the splint is sleeved with a limiting rod.

[0006] As a preferred embodiment, a closing plate is connected to the outer surface of the exhibit storage groove. A collar is fixedly connected to one side of the closing plate. A rotating rod is sleeved on the inner wall of the collar. A pull ring is fixedly connected to the outer surface of the closing plate.

[0007] As a preferred embodiment, the inner wall of the collar is rotatably connected to the outer surface of the rotating rod, and the outer surface of the rotating rod is fixedly connected to the inner wall of the exhibit storage groove.

[0008] As a preferred embodiment, one end of the spring is fixedly connected to the inner wall of the exhibit storage groove, and the other end of the spring is fixedly connected to one side of the clamping plate.

[0009] As a preferred embodiment, the outer surface of the baffle is snap-fitted with one side of the box body.

[0010] As a preferred embodiment, the inner wall of the clamping plate is slidably connected to the outer surface of the sliding rod.

[0011] As a preferred embodiment, the inner wall of the clamping plate is slidably connected to the outer surface of the limiting rod.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] The present utility model facilitates the fire-fighting personnel to conduct on-site evidence collection work after a fire by providing an evidence collection box body, and facilitates the staff to carry the evidence collection box through the handle. The box body is provided for storing tools required for evidence collection and classifying and placing the exhibits after evidence collection, which is convenient for the fire-fighting personnel to conduct later inspections. By opening a plurality of exhibit storage grooves inside the box body, the classification of exhibits is realized, and the situation where exhibits are randomly stacked together will no longer occur, which is convenient for the fire-fighting personnel to take and ensures the normal progress of the inspection work. By providing a closing plate to protect the exhibits inside each exhibit storage groove and prevent them from falling, it is ensured that the exhibits will not be damaged. By providing a clamping plate to clamp and fix the exhibit bag containing the exhibits, it is ensured that the exhibit bag will not fall, reducing damage to the exhibits.

[0027] Working principle:

[0028] As Figures 1-4As shown in the figure, when the fire-fighting staff uses the evidence collection box body 1 to conduct evidence collection work at the fire scene, first, the staff takes out the evidence collection tools inside the placement groove 7 for evidence collection work. Then, the staff classifies and places the evidence bags that have been collected inside the evidence storage groove 6. The spring 13 drives the clamping plate 14 to slide on the surface of the sliding rod 12, so as to clamp one end of the evidence bag, thus realizing the fixation of the evidence bag and ensuring that the evidence bag will not fall. Then, the limiting rod 15 is used to limit the clamping plate 14 to ensure that the clamping plate 14 will not rotate. After clamping the evidence bag, the staff drives the closing plate 8 to move by the rotational connection between the collar 10 and the rotating rod 11, so as to protect the evidence bag inside. After the evidence collection work is completed, the staff drives the baffle 2 to move by the hinge 4, so as to realize the closing work of the baffle 2 and the box body 3, and carry the evidence collection box body 1 through the handle 5.
