Description

Technical Field

[0001] The utility model relates to the field of biological trace detection equipment, in particular to a biological trace targeted display equipment. Background Art

[0002] Targeted biological trace display is a new technology that can use laser light source combined with potential biological trace evidence display technology to help on-site investigators find potential biological traces on the surface of difficult objects and ensure the original DNA biological characteristics of biological evidence. This technology can be used for large-scale non-destructive searches of various types of biological evidence at the scene, such as saliva stains, semen stains, nails, teeth, bone fragments and fingerprints on painted walls.

[0003] Targeted biological trace visualization is mainly used in the field of criminal investigation. This instrument uses the "targeted discovery of biological traces and DNA locations" technology, combined with advanced laser sources and new potential biological evidence visualization technology, to help on-site investigators quickly discover potential biological traces on the surface of difficult objects. For example, at the scene of a robbery, investigators can spray developer reagents on bricks and then use a targeted biological trace discovery instrument to irradiate them with lasers in a darkroom environment. After filtering and discovering fluorescent spots, these biological traces can be extracted with flocked swabs to provide valuable samples for subsequent DNA analysis.

[0004] The existing targeted biological trace display device needs to be moved outdoors for laser searchlighting if the crime scene is outdoors. During this process, due to the uncertainty of the outdoor environment, the stability of the biological trace display device cannot be guaranteed when placed outdoors. If the outdoor ground is rugged, the targeted biological trace display device needs manual control to maintain its stability, which makes it inconvenient to place it stably, affecting the efficiency of biological trace detection.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-3 The biological trace targeted display device shown includes a targeted searchlight 1. When the organism comes into contact with the environment, the biological traces left behind will be accompanied by shed cells and free amino acids. The matching developing reagent is sprayed into the environment. After the reagent reacts with the free amino acids for a period of time, the laser output by the targeted searchlight 1 is irradiated, and the parts where the free amino acids are distributed can be stimulated to produce fluorescent spots, thereby showing the location of the biological traces.

[0024] In order to facilitate the angle adjustment of the targeted searchlight 1, a positioning arm 2 is connected to the shell of the targeted searchlight 1 through a rotating shaft, and a support seat 3 is provided at the bottom end of the positioning arm 2. A base 4 parallel to the support seat 3 is provided below the support seat 3. The support seat 3 and the base 4 form a mezzanine space, and a plurality of equidistantly distributed connecting sleeves 5 are provided in the mezzanine space along a circular trajectory.

[0025] When the targeted searchlight 1 is used outdoors, in order to maintain the stability of the base 4 and the entire targeted display device, a support rod 6 is coaxially distributed with the connecting sleeve 5. The support rod 6 runs through the support seat 3 and the base 4, and the support rod 6 can be raised and lowered along the distribution direction of the connecting sleeve 5. The bottom end of the support rod 6 is provided with an embedded rod 7 that can move synchronously with it.

[0026] As the support rod 6 moves up and down, the embedding rod 7 can be embedded in the ground according to work requirements, reducing the impact of the rugged ground on the stability of the targeted display device. The targeted display device can stably and comprehensively implement biological trace detection work in an outdoor environment. The scope of application of the targeted display device is expanded. The bottom end of the entire embedding rod 7 is a conical structure, which can reduce the damage to the ground caused by the embedding rod 7 when it is embedded in the ground, and improve the tightness of the connection between the embedding rod 7 and the ground.

[0027] like Figure 4 , Figure 5 As shown, the connecting sleeve 5 and the support rod 6 are both provided with channels, and the inner side wall of the channel provided on the support rod 6 is provided with a plurality of equidistantly distributed alignment blocks 61 from top to bottom, and the surfaces of the alignment blocks 61 are provided with accommodating grooves 611 .

[0028] The passage opened on the support rod 6 is provided with a limit rod 8 passing through the passage, and a pair of movable plug blocks 9 are provided on the inner side of the limit rod 8. In the natural state, the plug blocks 9 are stuck on the inner side of the receiving groove 611. As the support rod 6 is raised and lowered, the plug blocks 9 are connected with the receiving grooves 611 opened on the surfaces of the alignment blocks 61 at different heights, which has an intercepting effect on the alignment blocks 61 at different heights. Furthermore, it has a locking effect on the support rods 6 moved to different positions. The support rod 6 is adjustable, and it can be adjusted to different heights with the embedded rod 7 to be suitable for different working environments.

[0029] like Figure 4 , Figure 5 As shown, a partition 81 is provided at the center of the limit rod 8 to divide the inner space into two parts, and a pair of movable plug blocks 9 are respectively located on both sides of the partition 81, and both sides of the partition 81 are connected to the plug blocks 9 through pressure springs 11. In a natural state, the elastic potential energy of the pressure spring 11 can make the plug blocks 9 tightly clamped on the inner side of the accommodating groove 611, maintain the stability of the support rod 6 after it moves to a specified height, avoid the deviation of the support rod 6 and the embedded rod 7, and further improve the stability of the entire targeted visualization device.

[0030] like Figure 5 As shown, in order to maintain the stability of the limiting rod 8 , the surface of the connecting sleeve 5 is provided with an alignment sleeve 62 , the alignment sleeve 62 is directly opposite to the outside of the channel, and the alignment sleeve 62 is connected to the limiting rod 8 .

[0031] like Figure 5As shown, in order to control the movement of the plug block 9 on the outside of the connection sleeve 5 and realize the purpose of connecting the plug block 9 with the receiving grooves 611 opened on the surface of the alignment block 61 at different heights, a control joint 10 is provided at the end of the plug block 9, and the control joint 10 extends to the outside of the limit rod 8. Pressing the control joints 10 located on both sides of the partition 81 can drive a pair of plug blocks 9 to move toward the partition 81, and the pressure spring 11 contracts. When the plug block 9 is separated from the receiving groove 611, the interception state of the alignment block 61 is released, leaving space for the support rod 6 to fall smoothly, until the plug block 9 is connected to the receiving grooves 611 opened on the surface of the alignment block 61 at other positions again.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
