Multifunctional shield with S-shaped guiding grooves

Abstract

The invention discloses a shield with S-shaped guiding grooves. The shield comprises a shield body; a transverse section on the front face of the shield body comprises a vertex and two side points, avertex intersecting line is composed of the vertex, side point intersecting lines are composed of the side points, and side edges are composed of the positions from the vertex to the side points, theheight of the vertex intersecting line is gradually decreased, the vertex intersecting line extends to the side point intersecting lines to form the side faces, and the front face of the shield body is axially symmetrical along the vertex intersecting line; the side faces comprise the guiding grooves and guiding ridges, the guiding grooves comprise groove heads, groove bodies and groove tails, thegroove bodies are formed by transversely extending from the groove heads in the vertex intersecting line to the groove tails in the side point intersecting lines, and the groove bodies are each arranged to be in an S shape; and the guiding ridges are arranged between the two adjacent guiding grooves, the S shape of each groove body comprises a complete S shape or partial S shape, or multiple continuous S shapes, the S-shaped groove bodies are internally provided with protruding points, or the S-shaped groove bodies are arranged to be friction faces, thus the sliding distance and the sliding resistance are effectively increased, the impact force to shield holding personnel is relieved, and the sliding speed of attaching objects is decreased.
