Abstract
Description
Technical Field
[0001] The utility model relates to the field of evidence collection equipment, in particular to evidence collection detection equipment. Background Art
[0002] There are many different crime scenes, which means that criminal technical police officers must be prepared to deal with various situations at the scene when they go to the scene. In many cases, potential traces on the surface of the object cannot be imaged using natural light. Therefore, in the face of changing investigation scenes, technicians need to have more technical means to non-destructively extract potential trace evidence at the scene during the on-site investigation. In order to facilitate the on-site evidence collection after identifying the evidence, detection equipment is needed to detect the evidence at the crime scene.
[0003] Most existing detection equipment uses a portable X-ray detection box or a portable high-definition ultra-thin X-ray detector to perform evidence operations at the crime scene. Due to the different crime scene environments, in order to improve the detection accuracy of the detection equipment and facilitate manual identification, most detection equipment is also equipped with lighting equipment that can increase the brightness of the crime scene, so as to improve the imaging quality of the detection equipment and facilitate on-site evidence collection by staff. However, the position of the lighting facilities on the detection equipment is mostly not adjustable. In different on-site environments, the lighting range is fixed. If it is necessary to perform detection operations in a narrow gap, the lighting lamp cannot be adjusted, so it is impossible to perform accurate lighting and detection operations in the narrow gap space.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a forensic detection device, comprising a detector and a base arranged below the detector, wherein a pair of lighting lamps are arranged on the detector, and the spacing between the pair of lighting lamps can be adjusted.
[0006] A bracket which can move synchronously with the illuminating lamp is arranged below the illuminating lamp. The illuminating lamp can be located inside the bracket and move up and down. When the illuminating lamp is lowered to a limit, a pair of the illuminating lamps are respectively located on both sides of the detector lens.
[0007] Furthermore, a follower arm is provided on the bracket, and a linkage gear is provided at the end of the follower arm. The follower arm and the linkage gear are both located above the detector, and the linkage gears are meshed and connected. When the lighting lamp and the bracket move, a pair of the follower arms adjust the size of their included angles, and the linkage gears mesh and rotate.
[0008] Furthermore, the bracket is provided with a guide bar, and the guide bar is provided with a longitudinally arranged accommodating channel. The bottom end of the lighting lamp is provided with an extension shaft, and the extension shaft passes through the accommodating channel. When the lighting lamp moves, the extension shaft is located inside the accommodating channel and moves synchronously.
[0009] A movable positioning screw sleeve is provided on the part of the extension shaft located outside the accommodating channel, and the positioning screw sleeve can adjust the distance between itself and the guide strip.
[0010] Furthermore, an anti-skid pad is provided on the positioning screw sleeve, and as the positioning screw sleeve slides closer to the guide bar, the anti-skid pad is pressed against the surface of the guide bar.
[0011] Furthermore, an interception ring capable of limiting the movement stroke of the positioning screw sleeve is provided at one end of the extension shaft away from the lighting lamp.
[0012] Furthermore, a support beam is provided at the top of the base, and the support beam is located behind the detector. A positioning plate is provided at the top of the support beam, and a hand frame is provided above the positioning plate.

DETAILED DESCRIPTION
[0021] 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.
[0022] Example: Reference Figure 1 , Figure 2 and Figure 3 The forensic detection device shown comprises a detector 1 and a base 2 arranged below the detector 1. A pair of illuminators 3 are arranged on the detector 1, and the distance between the pair of illuminators 3 is adjustable.
[0023] A bracket 4 is provided below the illuminating lamp 3 and can move synchronously therewith. The illuminating lamp 3 can be located inside the bracket 4 and move up and down. When the illuminating lamp 3 is lowered to the limit, a pair of illuminating lamps 3 are respectively located on both sides of the lens of the detector 1.
[0024] A follower arm 5 is provided on the bracket 4, and a linkage gear 6 is provided at the end of the follower arm 5. The follower arm 5 and the linkage gear 6 are both located above the detector 1, and the linkage gear 6 is meshed and connected. When the illuminating lamp 3 and the bracket 4 move, a pair of follower arms 5 adjust the size of their included angles, and the linkage gears 6 mesh and rotate to achieve the purpose of adjusting the distance between the pair of illuminating lamps 3.
[0025] Therefore, in the process of the follower arm 5 adjusting its angle and prompting the lighting lamp 3 to adjust its spacing, the lighting range can be expanded or reduced, which is convenient for the staff to focus on a certain place to carry out detailed lighting and detection work. It is also convenient for the staff to carry out comprehensive detection operations on the environment, so that the lighting lamp 3 can be adjusted according to different detection environments, and has the advantage of flexible adjustment to adapt to different lighting environments and different lighting needs.
[0026] like Figure 4As shown, the bracket 4 is provided with a guide bar 41, and the guide bar 41 is provided with a longitudinally arranged accommodating channel 42. The bottom end of the lighting lamp 3 is provided with an extension shaft 7, and the extension shaft 7 passes through the accommodating channel 42. When the lighting lamp 3 moves, the extension shaft 7 is located inside the accommodating channel 42 and moves synchronously.
[0027] A movable positioning screw sleeve 8 is provided on the portion of the extension shaft 7 located outside the accommodating channel 42. When the extension shaft 7 moves to a specified position along with the lighting lamp 3, the positioning screw sleeve 8 can adjust the distance between itself and the guide bar 41 to maintain the stability of the lighting lamp 3.
[0028] If the lighting lamp 3 is lowered to the limit, a pair of lighting lamps 3 are respectively located on both sides of the lens of the detector 1, which can reduce the space occupied by the lighting lamp 3 and enable precise lighting and detection operations to be carried out deep into a narrow space. During the detection process, the phenomenon of the lighting lamp 3 being blocked can be effectively avoided, which is suitable for detection needs in a narrow space.
[0029] like Figure 4 As shown, in order to improve the tightness of the positioning screw sleeve 8 and the guide strip 41 when in contact, an anti-skid pad 9 is provided on the positioning screw sleeve 8. As the positioning screw sleeve 8 slides close to the guide strip 41, the anti-skid pad 9 is pressed against the surface of the guide strip 41, which can improve the friction force when the positioning screw sleeve 8 and the guide strip 41 are in contact, and effectively avoid the phenomenon of sliding along the distribution direction of the guide strip 41 caused by the loosening of the positioning screw sleeve 8. Maintaining the stability of the extension shaft 7 further ensures the stability of the lighting lamp 3.
[0030] like Figure 4 As shown, in the process of screwing the positioning screw sleeve 8 , in order to prevent the positioning screw sleeve 8 from falling off the extension shaft 7 , an interception ring 10 that can limit the movement stroke of the positioning screw sleeve 8 is provided at one end of the extension shaft 7 away from the illuminating lamp 3 .
[0031] like Figure 3 As shown, a support beam 21 is provided at the top of the base 2, and the support beam 21 is located behind the detector 1. A positioning plate 22 is provided at the top of the support beam 21, and a hand-clip frame 23 is provided above the positioning plate 22. In order to maintain the stability of the follower arm 5 and the linkage gear 6 and install them firmly, the follower arm 5 and the linkage gear 6 need to be arranged inside the interlayer space formed by the hand-clip frame 23 and the positioning plate 22. It has a certain protective effect on the follower arm 5 and the linkage gear 6.
[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.
