Problems solved by technology

In the face of such attacks, the shields of the prior art used by law enforcers can generally resist the direct damage of the throwing liquid to the shield holder, but since the surface of the shield is a plane or arc surface, the throwing liquid will splash irregularly on the shield surface , changing directions, throwing liquids can easily cause harm to other law enforcement officers in coordination

Embodiment 1

[0031] Embodiment 1: as Figure 1-4 As shown, a multifunctional shield with an S-shaped guide groove includes a shield body 1, a handle 4, a pad 2 and an elbow locking and fixing device 3, and the shield body 1 includes a shield body front 100 and a shield body back 140, the pad 2 is connected to the back side 140 of the shield body, the handle 4 and the elbow locking fixture 3 are connected to the shield body 1 through the pad 2, and the front side of the shield body 100 has a transverse section Contains a vertex and two side points, the vertex forms the vertex intersection line 104, the side points form the side point intersection line 105, the height of the vertex intersection line 105 gradually decreases and extends to the side point intersection line 110 to form the side surface 106, the The shield body front 100 is axially symmetrical along the vertex intersection line 104, and the shield body front 100 is a convex arc surface, an inverted V-shaped surface or an arc surf...

Embodiment 2

[0042] Such as Figure 6 As shown, in this embodiment, the groove body 101b is optimized on the basis of Embodiment 1. The groove body 101b includes the groove edge 101b1 and the groove edge 101b2. When the groove body 101b extends from the groove head 101a to the groove tail 101c , the vertical height gradually decreases, and the vertical height refers to the distance perpendicular to the shield tail 120 at any point on the slot edge 101b1. At the same time, the groove side 101b1 and the groove side 101b2 gradually approach when extending from the groove head 101a to the groove tail 101c, so when the groove body 101b extends along the groove head 101a to the groove tail 101c, the opening size of the groove body 101b gradually decrease.

[0043] In this embodiment, for projectiles or liquids, the shield can have an effect similar to that of Embodiment 1, which will not be repeated here. In this embodiment, when attacking with sticks, one of the motion trajectories is as foll...

Abstract

The invention discloses a multifunctional shield with S-shaped guiding grooves. The multifunctional shield comprises a shield body, wherein the horizontal cross section of a shield body front surface comprises apices and two lateral points; the apices are combined into an apex intersecting line; the lateral points on each side are combined into a lateral point intersecting line; each apex and a corresponding lateral point are combined into a lateral edge; the height of the apex intersecting line is gradually reduced, and the apex intersecting line extends to each lateral point intersecting line to form a lateral side; the shield body front surface is axially symmetrical along the apex intersecting line axis; each lateral side comprises the guiding grooves and guiding ridges; each guiding groove comprises a groove head, a groove body and a groove tail; each groove head of the apex intersecting line transversely extends to the groove tail of the corresponding lateral point intersecting line to form the corresponding groove body; each groove body is formed in an S shape; each guiding ridge is arranged between two corresponding adjacent guiding grooves; and the S shape of each groove body comprises a complete S shape, or partial S shape, or a plurality of continuous S shapes. Through the adoption of the multifunctional shield, sliding distance and sliding resistance are effectively increased, impact force to a person holding the shield is relieved, and the sliding speed of an attacking object is reduced.

Description

technical field [0001] The invention relates to a shield, in particular to a police shield with guiding protection function. Background technique [0002] Shields are an ancient defensive weapon. Soldiers holding shields can effectively block the enemy's weapons and protect their own lives. In ancient combat, whether in the history of China, ancient Greece or ancient Rome, the shield is a very important weapon for tactical use and has been developed to this day. Although the glory of the shield in military use no longer exists today, the shield has a new life in the field of modern police use. In the current atmosphere where the world pattern tends to be peaceful, large-scale wars are unlikely to occur, but individual criminal activities within the country frequently occur. Therefore, the personal safety issues faced by police officers are the first to bear the brunt. At this time, police shields It has played a very important role in the field of single police protection....
