Multifunctional shield Technical field

The invention relates to a shield, in particular to a police shield with a guiding protection function.

Background technique

The shield is an ancient defensive weapon. The soldier's hand shield can effectively shield the enemy's weapons and protect their own lives. In ancient combat, in the history of China, ancient Greece or ancient Rome, shields have been a very important weapon for tactical use and have been developed ever since. Although the brilliance of the shield in military use no longer exists, the shield has renewed its life in the modern police field. In the current atmosphere of the world's pattern of peace, large-scale wars are unlikely to occur, and individual criminal activities within the country are frequently repeated. Therefore, the personal safety problems faced by police officers are the first to bear the brunt. Played a very important role in the field of single police protection.

Shields used in modern police fields, in police enforcement operations, in the face of rioters and low-intensity conflicts, shields are known as effective tools for police civil law enforcement.

When a modern police shield is attacked, it is mainly subject to the following attacks:

1. Attacks on equipment such as sticks: When criminals carry out such attacks, they usually wave or strike the shield by holding a stick or the like. In the shields of the prior art, the shield surface is usually a plane shield surface and a circular surface shield surface. If the front of the shield is flat and the shield is subjected to such an attack, the force of the stick will be mostly carried by the shield and transmitted to the arm of the law enforcement officer. It is easy to cause damage due to excessive force. In more serious cases, the shield may be disengaged. Loss of protection; if the front of the shield is a convex curved surface, when the shield is subjected to such an attack, the stick will slide along the shield surface, which can effectively unload a certain impact force, but since the shield surface has no guiding effect, the stick will be irregular. The sliding along the surface of the shield is not conducive to law enforcement officials to determine how to counterattack and disarm, on the other hand, it may also cause personnel to cooperate with law enforcement.

2. Attacks on flying objects such as flying stones and bricks: When criminals carry out such attacks, they usually take the means of direct throwing and throw the flying stones and bricks to the law enforcement. In the face of such attacks, the prior art shields used by law enforcement officers can generally resist the damage of the throwing objects to the shielded personnel, but since the shield surface is a plane or a circular arc surface, the throwing objects will slide irregularly on the shield surface. The reversing of throwing objects can easily cause damage to other law enforcement personnel who are coordinated.

3, flammable, corrosive liquid attack: When criminals carry out such attacks, they generally use direct throwing means to throw flammable and corrosive liquids to law enforcement. In the face of such attacks, the prior art shields used by law enforcement officers can generally resist the direct damage of the throwing liquid to the shielded personnel, but since the shield surface is a flat or circular surface, the throwing liquid will splash irregularly on the shield surface. , change direction, throwing liquids, but it is easy to cause damage to other law enforcement personnel.

For example. When the stone attack is strong, the stone collides with the front 100 of the shield. Since the shield front 100 and the shield bottom 103 form a V-shaped structure, the shield front 100 is composed of the first guiding groove 101, so the stone will first contact the first guiding. The slot 101 has different motion curves due to different positions of the contacts, wherein the movement of the first motion track 110 is a more common form, such as the first motion track 110, and the stones are along the first in the first guiding slot 101. The guide groove 101 slides from the groove head 101a toward the groove tail 101c and falls into the second guide groove 106. Since the second guide groove 106 includes the groove opening 106a and the groove bottom 106b, the groove opening 106a has a size greater than or equal to The groove bottom 106b is sized, and the second guiding groove 106 may be a U-shaped groove or a V-shaped groove, so that the throwing material sliding into the second guiding groove 106 at this time will bounce back along the second guiding groove 106 to the front of the shield front 100. Can counterattack the attacker and play a very good deterrent role.

When the stone attack is not strong, when the stone attacks the shield front 100, since the shield front 100 is composed of the first guiding groove 101, the stone will first contact the first guiding groove 101, because the two shields are 100 shield front. The V-shaped surface composed of 103 and the protective plate 105 disposed at the top of the shield front surface 100, the stone moves along the second movement track 120, and the stone in the first guiding groove 101 along the first guiding groove 101 from the groove head 101a to the groove tail The 101c slides and falls into the second guiding groove 106 and falls into the bag-shaped capturing device 108 along the second guiding groove 106, so that the throwing object can be effectively captured, and the shield person and the coordination personnel are well protected.

When the attacking object is a liquid, when the liquid hits the shield front 100, since the shield front 100 is composed of the first guiding groove 101, the liquid will first contact the first guiding groove 101, since the two shields face 100 shield bottom 103 The V-shaped surface and the protective plate 105 disposed on the top of the shield front surface 100, so that the liquid portion will splash to the front of the shield front surface 100, part of the liquid will move along the second movement track 120, and the liquid is guided along the first guide groove 101. The groove 101 slides from the groove head 101a toward the groove tail 101c, and falls into the second guide groove 106 and falls into the bag-shaped catching device 108 along the second guide groove 106, thereby effectively preventing the liquid from being directed to both sides of the shield. And the top side splash, a good protection for the shield and the coordination staff.
