Portable material evidence signboard

Technical Field

The utility model relates to a scene material evidence signboard belongs to record, measuring equipment field, and specifically speaking is a portable material evidence signboard.

Background

After a case occurs, a field technical prospecting personnel must arrive at the case site at the first time, protect the site, draw a prospecting range and take pictures of the site condition and important material evidence. The material evidence signboard both plays the supplementary effect of drawing the material evidence in the investigation, plays the effect of warning the scene material evidence again, needs investigation personnel to give sufficient attention to, avoids the mistake action to cause pollution, disappearance or damage to the material evidence. Some sites are located outdoors, the sites of the cases have the characteristics of wide range of the sites for case distribution, a large quantity of trivial material evidence, dark night exploration light, difficulty in control and the like, and the material evidence signboard plays an indispensable role in protecting the sites.

Most of material evidence signboard sold in the market at present is provided by social manufacturers, takes a set as a unit, has higher price and single function, and cannot well combine the requirements of investigation work and technology of basic public security organs; the current laws and regulations do not make corresponding standard specifications for police equipment such as material evidence signboards and the like, and the research and development strength of the police equipment is insufficient, so that no breakthrough innovation exists in the field of on-site investigation. Due to the reasons, the existing material evidence signboard is limited in action range and inconvenient to store, a dark place is difficult to see, and a scale is inconvenient to use;

for example, the open-air field physical evidence signboard of the patent number 201520860058.3 is complicated in process, not easy to store, not easy to see clearly at night, fixed in scale and inconvenient to use in field measurement.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model discloses a technical scheme as follows:

the utility model provides a portable material evidence signboard, includes the base plate, its characterized in that: the device also comprises a clamping bag and a graduated scale;

the base plate is divided into a front base plate and a rear base plate, and the front base plate is movably connected with the rear base plate through a rotating piece; the card bag sets up on the base plate, place the information card in the card bag, the base plate lower part is provided with the draw-in groove, place the scale in the draw-in groove.

As a preferred technical solution, the rotating member is a rotating shaft, and the rotating shaft is disposed at the upper edges of the front substrate and the rear substrate.

Preferably, the upper edges of the front and rear substrates are unfolded or folded around the rotation axis.

As a preferred technical scheme, the portable material evidence signboard further comprises a surface layer, wherein the surface layer is a fluorescent material layer coated on the surface of the substrate.

As preferred technical scheme, the symmetry sets up two scales in the draw-in groove, the scale outer end has the spacing chimb, scale and draw-in groove sliding fit.

As a preferred technical scheme, one side of the clamping bag is provided with an opening, and the clamping bag at the opening side is provided with an arc-shaped notch.

As a preferable technical scheme, one of azimuth and number material evidence information is marked on the information card.

The utility model has the advantages that:

the utility model discloses a portable material evidence signboard, the front base plate and the back base plate are opened or folded around the rotating shaft, the structure is simple, the carrying is convenient, and the space is saved; one of position and number material evidence information is marked on the information card, and the material evidence is identified in detail; the graduated scale can well meet the requirements of on-site investigation of the scale, well solve the problem of fold bending deformation of the traditional scale made of soft materials during physical evidence photographing, and can also be combined into a square to correct the inclination of a photographed object; the surface layer of the signboard is made of fluorescent materials, so that the information of the signboard can be clearly displayed in dark light.
