Description

Adjustable on-spot investigation current shoes

Technical Field

The utility model relates to a criminal investigation technical field specifically indicates an adjustable on-spot investigation current shoes.

Background

The on-site investigation passing pedal is an investigation equipment which can pass in and out of the site in the initial stage of on-site investigation, and is mainly formed by adding a plurality of point-shaped supporting points on a rectangular bottom plate. The field investigation pedal is mainly used by criminal technicians and forensic doctors in major and case sites, the pedals are sequentially laid on the ground when entering the site to form a rapid channel, the main functions of the field investigation pedal are to fix the original state of the site, judge the vital signs of related personnel and the like, and the field investigation passing pedal is used to extremely damage the site ground and leave no trace similar to a shoe print.

In conclusion, the main functions of the on-site survey passing pedal are represented in the following two aspects:

first, the field environment, trace and physical evidence are protected to the maximum extent, and the change of the original state of the field is reduced with the minimum cost. Such as ensuring that ground footprints, crime tools, biological material evidence (bloodstains, saliva, fine spots, hair and the like), trace material evidence, the overall state of the site and the like are not damaged.

Secondly, the photographers take fixed pictures after using the on-site survey passing pedal before other related personnel enter the site, which is the most primitive state of the site, and is very important for on-site analysis and on-site reconstruction which are carried out later, so the on-site survey pedal is important equipment which is indispensable in important affairs and case on-site survey.

The problems and disadvantages of the prior art mainly include the following aspects:

(I) large occupied space

At present, the size and the weight of the whole set of spot investigation passing pedal are still huge. Especially when meeting specific places such as stairs, the utility model is limited by the shape of the pedal, so that the paving can not be carried out and the proper function of the pedal is lost.

(II) inconvenient to carry and move

In addition, in order to fix the original state of the field, a passing pedal needs to be laid when the picture is shot on the field, and when the field area is large, the number of rooms is large, and the structures of the rooms are complex, the workload of moving the whole set of pedals is extremely complex, so that the speed of entering the field is slow.

(III) the material of the upper and lower contact surfaces of the pedal will damage the field

The twenty-seventh regulation of public security organ criminal case site investigation and inspection rules: "public security agency shall equip the necessary safety protection facilities and appliances for the field survey and inspection personnel". The footboard upper surface is the position of criminal technical staff contact footboard, and the contact surface all generally adopts materials such as organic glass (ya keli) surface, stainless steel frame, rubber or plastics footing contact point on the footboard at present, very easily leads to criminal technical staff to slip, causes personnel's unnecessary injury.

In addition, the lower surface of the pedal is a position contacted with the ground on site, especially for the relatively smooth and compact surfaces of a large number of floor tiles, floors and the like in indoor sites, if the fulcrum of the pedal is not stable enough, especially under the conditions of high moving speed or excessive treading force, the pedal can cause instability of personnel, and in addition, important marks and material evidence on the ground can be easily damaged in the sliding process.

(IV) Pedal Placement area has limitations

For the field of the very big cases, a plurality of police species are needed to work simultaneously. At present, in actual work, the whole set of pedals generally only comprises four pedals, the number is limited, and ground traces and material evidence can be damaged by adopting a plurality of sets of pedals. When the wounded personnel are rescued or the corpses are moved, the limited safe foot falling points not only influence the working progress and delay the best time for solving the case, but also possibly damage the on-site traces and material evidences.

In order to solve the problem of complex inconvenience in the use process of the pedal, criminal technicians sometimes use field investigation shoe covers to replace the pedal, the use of the shoe covers can avoid substances adhered to soles from falling on the field and replace the pedal to a certain extent, but the plastic films used by the shoe covers still leave dust layer reduction marks on the field, the problems that the shoe covers are large in abrasion degree and difficult to distinguish with shoe marks without obvious patterns and the like exist, in addition, the contact area of the shoe covers and the ground is large, and the field ground marks and material evidence can be damaged unintentionally.

Therefore, the current on-site investigation passing pedal is inconvenient to use, such as large in size, large in quantity, complex to carry and use and the like, and the on-site investigation efficiency is low. All the problems cannot be solved by other means, so that the improved design of the on-site exploration traffic pedal is imperative.
