Description

Technical Field

[0001] The utility model belongs to the technical field of criminal investigation equipment, and specifically relates to a shoe sole pattern photographing device. Background Art

[0002] In the field of criminal proceedings, expert opinions are one of the eight statutory evidence in criminal cases. For footprints left by suspects at the crime scene, judges often require on-site investigators to issue an expert opinion on whether the footprints were left by the shoes worn by the suspect. According to the requirements for on-site footprint inspection and identification, a clear and complete photo of the suspect's shoes must be attached to the expert opinion.

[0003] Since the soles of some shoes, especially the soles of sports shoes, are not on the same plane, the photos of the soles may be blurry. The usual practice now is to use building blocks to pad under the toes so that the heel, arch and forefoot of the sole are as close to the same plane as possible. This method is clumsy, time-consuming and labor-intensive, and footprint inspection and identification requires that a scale be added to the photographed footprints to ensure that the scale and the sole are in the same plane as much as possible. It is relatively difficult to ensure that the heel, arch and forefoot of the sole are as close to the same plane as much as possible and to take a clear scale photo. In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to facilitate the adjustment of the light, the operating panel is further provided with a light button near the moving button, the four corners of the operating panel are connected with light bundles, the upper end of the light bundle is fixedly connected to a bowl lamp, the operating panel is fixedly connected with a light board, the upper end of the light board is fixedly connected to a glass plate, and the light bundle, bowl lamp and light board are all electrically connected to the light button.

[0007] In order to improve the effect of the photo, further, a background cloth is arranged on the glass plate.

[0008] In order to facilitate the fixing of the background cloth, further, two groups of clamps for clamping and fixing the background cloth are symmetrically fixedly connected to the operation panel.

[0009] In order to facilitate taking out the scale, further, a rotating plate is fixedly connected to a position on the movable plate at one end of the scale via a torsion spring.

[0010] In order to facilitate carrying, further, the light bundle is rotatably connected to the glass plate through a hinge.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: compared with the existing sole pattern photography technology, the utility model uses a movable rod, a buffer plate, and a tensioning spring to stretch the shoe so that the sole is in a plane, and uses an electric telescopic rod to send the scale to the same plane as the shoe, and then completes the photography.
