The shield surface in the shield in the prior art is usually a plane shield surface and a circular arc shield surface. If the front surface of the shield is a plane, when the shield is attacked, the force of the stick can be mostly supported by the shield and conducted to the arms of law enforcement officers, so that the shield is easily injured due to excessive force, and in a more serious case, the shield can be out of hand and lose protection; if the shield openly is the arc surface, when the shield suffered this type of attack, the stick can slide along the shield face, can the certain impact force of effectual uninstallation, nevertheless because the shield surface does not have the guide effect, so the stick can be irregular slide along the shield surface, is unfavorable for law enforcement personnel to judge how to counterattack and pay for the instrument on the one hand, and on the other hand, also can cause the personnel's injury of law enforcement in coordination to injure.

2. Attack by throwing objects such as flying stones, bricks and the like: when criminals carry out such attacks, the criminals generally adopt a direct throwing means to throw the criminals to law enforcement through flying stones and bricks. In the face of such attacks, the existing shield cannot catch the thrown object, the shield in the prior art adopted by law enforcement can generally resist the injury of the thrown object to shield holding personnel, but the thrown object can irregularly slide on the shield surface due to the fact that the surface of the shield is a plane or a circular arc surface, and the reversed thrown object is extremely easy to cause the injury of other cooperative law enforcement personnel.

3. Combustible and corrosive liquid attack: when criminals carry out such attacks, combustible and corrosive liquids are generally thrown to law enforcement persons by means of direct throwing. In the face of such attacks, shields in the prior art adopted by law enforcement officers can generally resist direct injury of the throwing liquid to shield holding personnel, but because the surfaces of the shields are flat surfaces or arc surfaces, the throwing liquid can irregularly splash and change directions on the shields, and the throwing liquid is extremely easy to cause damage to other cooperative law enforcement officers.

In addition, the shield in the prior art also has insufficient capability when serving as a weapon to attack criminals, most of the shields are pure protective instruments, cannot collect and pay the attacking object, cannot capture the thrower of the attacker or the baton and other weapons, and achieves the effect of both attack and defense.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example 1: as shown in fig. 1-3, a multifunctional shield with a capturing device comprises a shield body 1, a handheld handle 4, a protection pad 2 and an elbow locking and fixing device 3, wherein the shield body 1 comprises a shield body front 100 and a shield body back 140, the protection pad 2 is connected with the shield body back 140, the handheld handle 4 and the elbow locking and fixing device 3 are connected with the shield body 1 through the protection pad 2, the shield body front 100 transverse section comprises a vertex and side points on two sides, the vertex forms a vertex intersecting line 104, the side points form a side point intersecting line 105, the vertex intersecting line 105 is gradually reduced in height and extends to the side point intersecting line 110 to form a side surface 106, the shield body front 100 is symmetrical along the axis of the vertex intersecting line 104, and the shield body front 100 is an outward convex arc surface, an inverted V-shaped surface or an arc surface; it may also be a convex trapezoid or other convex shape. The convex surface can effectively unload the attacking force when being attacked, and shield-keeping personnel are protected.

The side surface 106 is provided with a guide groove, a corrugated surface is formed by the guide groove 101, the guide groove 101 comprises a groove head 101a, a groove tail 101c and a groove body 101b, and the groove head 101a transversely extends to the groove tail 101c from a top point intersecting line 104 to a side point intersecting line 105 to form the groove body 101 b. An optional technical scheme is that a catching device 5 is arranged on a groove body 101b or a groove tail 101c of the guide groove 101; another alternative technical solution is that the groove body 101b and the groove tail 101c of the guide groove 101 are both provided with a catching device 5, and the catching device 5 is connected to the shield through welding or screws.

Preferably, the guide groove 101 is a V-shaped guide groove or a U-shaped guide groove, the side surface 106 is a V-shaped or U-shaped corrugated surface formed by the continuous guide grooves 101, and the V-shaped or U-shaped corrugated surface facing downward forms a finished protective surface on the front surface 100 of the shield body, so that various attacks can be more effectively dealt with. The fold plane of the V-shape may be completely continuous or may be discontinuous, as will be appreciated by those skilled in the art. The continuous V-shaped or U-shaped wrinkled surfaces on the left side and the right side are attractive as a whole and have deterrent force. When the shield is attacked by a stick, a stone and other throwing objects or liquid, the shield can be beneficial to forming a multi-dimensional inclined plane on the front side of the shield, so that the shield can realize comprehensive coverage and comprehensive protection.

As shown in fig. 3-7, when encountering a projectile attack, the projectile first contacts with any one of the two side surfaces 106 of the front surface 100 of the shield body, and since the side surfaces 106 are provided with a corrugated surface formed by continuous guide grooves 101, and the guide grooves 101 extend transversely on the outer convex surface along the vertex intersection line 104 toward the side point intersection line 105, it is obvious that the vertex intersection line 104 is higher than the side point intersection line 105, and the vertex intersection line 104 end of the guide grooves 101 is higher than the side point intersection line 105 end of the guide grooves 101, the guide grooves 101 have the function of guiding the projectile or other projectiles along the vertex intersection line 104 toward the side point intersection line 105. Therefore, due to different kinds, impact inertia and contact angles of the attacking object, the following may occur:

1. a rebound attack mode: as shown in fig. 4-5, a shield keeper faces the guide groove 101 of the shield to a throwing object according to the movement track of the throwing object, so that the falling point of the throwing object is vertical to the shield, in this case, the throwing object directly bounces back to the front of the shield body along the curved surface of the guide groove 101 to play a role in frightening and striking the rioter, and as the guide groove 101 is V-shaped or U-shaped, as shown by a U-shaped groove bounce track 152a and a V-shaped groove bounce track 152b, the shield keeper can use the effect of the throwing object colliding with the guide groove to bounce to the front to counter the rioter after training, so as to deter the rioter from attacking.

2. A capture mode: as shown in fig. 6 to 7, the catching device 5 is a cartridge type catcher 520, and the cartridge type catcher 520 includes a catching opening 521, a catching body 522 and a catching outlet 523. An optional technical scheme is that the catching device 5 is arranged on the groove body 101b and the groove tail 101c of the guide groove 101, wherein the catching opening 521 is made of an elastic material, the catching body 522 and the catching outlet 523 are made of a rigid material, the whole cylindrical catcher 520 can also be made of a high-strength flexible material or a semi-rigid material, the flexible or semi-rigid catching opening 521 can deform in the process of catching the stick and wrap the stick, and the function of blocking is achieved by increasing friction force and limiting. The cartridge type catcher 520 of the present embodiment mainly catches an attack object such as a stick.

Specifically, after an attacker strikes the stick on the front face 100 of the shield body, since the front face 100 of the shield body is a wrinkled surface formed by the guide groove 101, the stick first contacts the guide groove 101, and due to the guiding effect of the guide groove 101, the stick slides in the guide groove 101 along the vertex intersection line 104 toward the side intersection line 105, and after the stick slides to the cylindrical catcher 520 provided in the groove body 101b, the semi-rigid or flexible catching opening 521 is expanded by a certain arc by the stick, and due to the limiting effect of the cylindrical catcher 520, the stick receives a large tightening force at the contact part with the catching opening 521, and the state at this time is defined as an initial catching stick state 601, and if the force applied to the stick by the attacker is small, the stick can be paid in the initial catching stick state 601; however, if the force applied to the stick by the attacker is large, the stick will continue to slide along the groove body 101b of the guide groove 101 due to the inertia effect and slide into the cylindrical catcher 520 provided at the groove tail 101c, which defines the state as the final stick catching state 602, and the impact force of the stick is rapidly attenuated due to the position limitation of the double-layered cylindrical catcher 520 at the groove body 101b and the groove tail 101c, thereby finally completing the stick catching. It should be understood by the shield personnel that, when encountering rod attack, the rod can be captured by using a single barrel-type catcher 520 or two catcher 520 can be selected according to the actual situation, so that in the present embodiment, the barrel-type catcher 520 is disposed on the trough body 101b or the trough tail 101c of the shield, or the barrel-type catcher 520 is disposed on both the trough body 101b and the trough tail 101c, so that the catching effect can be achieved for different attack situations.

Example 2:

as shown in fig. 8 to 9, this embodiment is an improvement of embodiment 1 in which the catching device 5 is provided as a cartridge type catcher 520, and the catching device 5 at the trough tail 101c is provided as a pocket catcher 510. A cylindrical catcher 520 is arranged on the slot body 101b, the bag-shaped catcher 510 comprises a bag opening 511 and a bag body 512, and the bag opening 511 is provided with a guide edge or an expansion slot. In a preferred embodiment, the bag mouth 511 is made of a rigid or semi-rigid material, and the bag body 512 is made of a corrosion-resistant fiber material. The embodiment can simultaneously give consideration to the capture and payment of the throwing objects and the stick-type attacking objects.

1. A rebound attack mode: the present embodiment has the same attack mode as that of embodiment 1 corresponding to the throwing object, and is not described herein again.

2. Capture mode 1: as shown in fig. 8, specifically, after an attacker strikes the stick on the shield body front surface 100, since the shield body front surface 100 is a corrugated surface formed by the guide groove 101, the stick first contacts the guide groove 101, and due to the guiding action of the guide groove 101, the stick slides in the guide groove 101 along the vertex intersection line 104 in the direction of the side intersection line 105, and after the stick slides to the cylindrical catcher 520 provided in the groove body 101b, the semi-rigid or flexible catching opening 521 is spread by the stick with a certain curvature, and due to the limiting action of the cylindrical catcher 520, the stick receives a large tightening force at the contact portion with the catching opening 521, and this state is defined as an initial catching stick state 601, and if the force applied to the stick by the attacker is small, the stick can be caught in the initial catching stick state 601. If the force applied to the stick by an attacker is large, the stick will continue to slide along the groove body 101b of the guide groove 101 due to inertia and slide into the bag-shaped catcher 510 arranged at the groove tail 101c, the bag mouth 511 is provided with a guide edge or an expansion groove, and can be guided and limited with the stick at this time, and the state at this time is defined as a final catching stick state 603, and the impact force of the stick is rapidly attenuated due to the double limitation of the cylindrical catcher 520 at the groove body 101b and the bag-shaped catcher 510 at the groove tail 101c, and the catching of the stick is finally completed. It should be understood by the shield person that, when a stick attack is encountered, a single bag-shaped catcher 510 may be disposed at the trough tail 101c to catch the stick, or a catcher 520 may be disposed at the trough body 101b to catch the stick doubly, according to the actual situation, so that the bag-shaped catcher 510 disposed at the trough tail 101c of the shield, or the barrel-shaped catcher 520 disposed at the trough body 101b may catch the stick under different attack situations.

3. Capture mode 2: specifically, as shown in fig. 9, when a projectile attack is encountered, the present embodiment is discussed by taking a stone as an example. After an attacker shoots stones on the front surface 100 of the shield body, shield holding personnel move the shield according to a throwing curve of the stones to enable the shield to have a certain inclination angle with the stones, because the front surface 100 of the shield body is a corrugated surface formed by the guide grooves 101, the stones firstly contact the corrugated surface formed by the guide grooves 101, and due to the guiding effect of the guide grooves 101 and the inertia effect of the stones, the stones slide in the guide grooves 101 along the top point intersecting line 104 to the side point intersecting line 105 direction, and due to the difference of gravity and the contact angle with the shield, the stones may slide along the surface of the corrugated surface formed by the guide grooves 101 in a wavy track and are finally captured by the bag-shaped catcher 510 at the groove tail 101c, as shown by a stone sliding track 701; alternatively, the stone may slide in the single guide groove 101 as shown by the stone sliding track 702 and finally be caught by the pocket catcher 510.

In a preferred embodiment, the bag mouth 511 is made of a rigid or semi-rigid material, and the bag body 512 is made of a corrosion-resistant fiber material. The rigid or semi-rigid mouth 511 is capable of limiting the insertion of the stick into the bag 512 without tearing the mouth 511, and the bag 512 is made of an anti-corrosive fiber material and is capable of capturing not only stones but also liquids, especially corrosive liquids.

Furthermore, it should be understood by those skilled in the art that it is within the scope of the present invention to change the corresponding number relationship between the catching device 5 and the guiding slot 101, such as 2 guiding slots 101 or more guiding slots 101 for each catching device 5.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
