Embodiment

[0040] A new type of portable traffic pedal includes a panel 1 and a frame structure. The main body of the frame structure is made of 7075 aluminum alloy, and its surface is copper-plated for corrosion resistance improvement. Its panel 1 is made up of several strip blocks 101, which form a surface that can be trampled and supported by the personnel who investigate the crime scene, such as figure 1 , image 3 and Figure 4 As shown, the strip blocks 101 are arranged parallel to each other and equidistant, the distance between two adjacent strip blocks 101 is ≥0.5 cm, and the width is ≥0.5 cm. The frame structure includes a front plate 201, a tail plate 202 and a connecting rod 203. The front plate 201 is similar or identical to the main body of the tail plate 202, and both are bent plate structures, that is, the same front plate connecting surface 2011 and tail plate connecting surface 2021 are formed. And the front-end plate support surface 2012 and the tail plate support su...

Abstract

The invention relates to the technical field of crime scene investigation, and provides a novel portal unobstructed footboard for solving the problems of inconvenient carrying and use of a traditionalunobstructed footboard, low paving efficiency during investigating in a crime scene, and easy shielding of sight. The novel portable unobstructed footboard comprises a panel, and a frame structure which is arranged at the bottom part of the panel, wherein the panel is formed by arranging a plurality of mutually parallel stripy blocks at equal intervals; the frame structure comprises a front end plate, a tail plate and a connecting rod; the two ends of the front end plate and the rear plate are correspondingly hinged with two ends of the connecting rod so as to form a parallelogram frame structure; the stripy blocks are arranged in parallel, and two ends of each stripy block are correspondingly riveted with the front end plate and the tail plate of the frame structure. The novel portable unobstructed footboard has the advantages of being convenient to open and store and use, small in overall size after being stored, convenient to carry and transport, convenient to adjust the shape after being extended, high in adaptability, free from sight shielding caused by the panel, and high in stability.

Description

technical field [0001] The invention relates to the technical field of crime scene investigation, in particular to a novel portable walking pedal. Background technique [0002] In recent years, due to the influence of domestic and foreign environments, serious violent crimes, especially violent terrorist crimes, and personal extreme violence cases have shown a clear upward trend.
