Description

Technical Field

[0001] This utility model relates to a clamp-type shield, belonging to the field of protective equipment technology. Background Technology

[0002] Pincer-style shields are mostly used for self-protection to avoid being harmed by irrational crowds. However, when the protector is attacked by the perpetrator with knives, clubs, etc., the existing shields can only block the perpetrator's attack by blocking the knife, club, etc., in order to protect themselves from harm. But when the protector is attacked by knives, clubs, etc. repeatedly, they are relatively passive.

[0003] The applicant's search revealed that Chinese patent CN116294818A discloses an integrated offensive and defensive riot control shield. This shield achieves its protective effect through the cooperation of a fixed inverted rack assembly and a locking inverted rack assembly. If an attacker strikes the shield with a knife, the shield can be secured to the fixed and locking rack assemblies by gripping the locking mechanism. A quick swing of the arm can then disarm the attacker. However, to prevent the knife from slipping out, the defender must pull the locking rack assembly to one side after clamping the knife, making the operation complex and prone to misoperation in emergency situations, which is detrimental to the defender's safety. Furthermore, the relatively small size of the fixed and locking rack assemblies in this patent means that the knife may not enter between them, potentially preventing successful disarming. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to propose a highly secure shield that can disarm the attacker when they are attacked by knives, clubs, etc.

[0005] To solve the above-mentioned technical problems, this utility model proposes a clamp-type shield, including a shield body, an activation bar, and two clamp arms, wherein the activation bar and the two clamp arms are parallel; the shield body is provided with a vertical groove with an opening at the top, the activation bar is inserted into the vertical groove from the opening of the shield body, and a first return spring is provided on the shield body to reset the activation bar; both sides of the activation bar are provided with a downward sloping surface that gradually tapers inward from top to bottom;

[0006] One end of the clamp arm is hinged to the shield body, and the other end is provided with a stepped first hook; the two clamp arms have a reset state retracted into the vertical groove and a clamping state extended from the vertical groove; a torsion spring is provided at the hinge of the clamp arm and the shield body, and the torsion spring keeps the two clamp arms in the clamping state in the natural state.

[0007] The shield body is provided with a locking mechanism for locking the clamp arm. The locking mechanism includes a lever installed on the shield body. One end of the lever is provided with a second hook that is adapted to the first hook of the clamp arm. The other end of the lever is provided with a locking switch for fixing the lever to the shield body or releasing it from the shield body. The shield body is provided with a second return spring for resetting the lever. The top of the second hook is provided with an upper slope surface that is in close contact with the lower slope surface.

[0008] When in use, if the defender is attacked with a knife, release the locking switch (equivalent to a safety device), causing the lever to detach from the shield body. At this point, the defender points the actuating bar towards the direction of the knife attack. The actuating bar moves downwards under pressure, and its lower slope presses against the upper slope of the lever, causing the lever's hook to move away from the actuating bar. This separates the clamp arms from the lever. Under the action of the torsion spring, both clamp arms simultaneously flip upwards, gripping the knife. By continuously flipping the shield, the defender can disarm the knife. Besides disarming knives, the same procedure can also be used to disarm clubs and other weapons.

[0009] It is evident that, in addition to the protective function of a traditional clamp-type shield (which cannot trigger a clamping action and can be used for ordinary blocking and impact), this utility model also has the function of disarming knives and clubs. It transforms the traditional shield from being able to passively block knives and clubs to resist the attacker's attack into one that can actively disarm knives and clubs, thus providing a higher level of protection and security.

[0019] Example 1: This example illustrates a pincer-type shield, such as... Figures 1-6 As shown, it includes a shield body 1, an activation bar 2, and two clamp arms 3. The activation bar 2 and the two clamp arms 3 are parallel. Preferably, the activation bar 2 is located between the two clamp arms 3.

[0020] The shield body 1 is made of two aluminum alloy plates connected by bolts. A handle is provided on one side of the shield body 1. The shield body 1 has a vertical groove 4 with an opening at the top; other directions are not restricted and can be closed or open. The activation bar 2 is inserted into the vertical groove 4 through the opening in the shield body 1. The shield body 1 is provided with a first return spring 5 to reset the activation bar 2. In this embodiment, the first return spring 5 is as follows: Figure 2 As shown, the starting bar 2 has a vertically extending elongated hole, and the shield body 1 has a support rod 15 passing through the elongated hole. The first return spring 5 is located in the gap between the support rod 15 and the elongated hole. To make the starting bar 2 move up and down more smoothly, preferably, the starting bar 2 is provided with a guide rail 16, and the shield body 1 is provided with a guide groove (not shown in the figure) that matches the guide rail.

[0021] One end of the clamp arm 3 is hinged to the shield body 1, and the other end is provided with a stepped first hook portion 8. Both clamp arms 3 have a retracted, recessed state within the vertical groove 4 (e.g., Figure 2 As shown), and the clamping state extending from the vertical groove 4 (as shown). Figure 3 (As shown in the figure). A torsion spring (not shown in the figure) is provided at the hinge between the clamping arm 3 and the shield body 1. The torsion spring keeps the two clamping arms 3 in a clamping state in its natural state. The top of the actuation bar 2 and the opposite sides of the two clamping arms 3 when in the clamping state can be provided with a flat surface with high friction. However, in order to better clamp knives and sticks, it is preferable that the top of the actuation bar 2 and the opposite sides of the two clamping arms 3 when in the clamping state are provided with serrations. The serrations have the function of preventing loosening, which can better disarm knives and sticks and protect the defender.

[0022] The shield body 1 is provided with a locking mechanism for locking the clamp arm 3. The locking mechanism includes a lever 13 mounted on the shield body 1. One end of the lever 13 is provided with a second hook 9 that matches the first hook 8 of the clamp arm 3. The other end of the lever 13 is provided with a locking switch for fixing the lever 13 to or releasing it from the shield body 1. The shield body 1 is provided with a second return spring 10 for resetting the lever 13. One end of the second return spring 10 is connected to the shield body 1, and the other end is connected to the lever 13. Preferably, as follows... Figure 2 As shown, the second return spring 10 can be positioned between the shield body 1 and the first hook portion 8 of the clamp arm 3. The two sides of the starting bar 2 are provided with a downwardly tapering slope 6, and the top of the second hook portion 9 is provided with an upwardly tapering slope 7 that is in close contact with the downwardly tapering slope 6.

[0023] It should be noted that the locking switch is existing technology. For example, a simple pin can be used for limiting the position. When the pin is inserted between the lever 13 and the shield body 1, the lever 13 is hinged and fixed to the shield body 1; when the pin is pulled out, the lever 13 is released from the shield body 1. Preferably, in this embodiment, the locking switch uses a limiting block hinged to the shield body 1. When the limiting block rotates along the hinge point, it can hold the lever 13 or move away from the lever 13. When the first hook of the clamp arm 3 hooks the second hook 9 of the lever 13, the limiting block holds the lever 13, thus fixing the lever 13 to the shield body 1. At this time, a protrusion can be provided on the limiting block and a corresponding recess can be provided on the shield body 1 to ensure that the limiting block is in a stable state when holding the lever 13. Of course, a more complex locking switch used in firearms can also be used.

[0024] In this embodiment, when the defender is attacked by a knife, the locking switch, which acts as a safety device, is released, allowing lever 13 to detach from the shield body 1. At this time, the defender directs the actuating bar 2 towards the direction of the knife attack. The actuating bar 2 moves downward under force, and the lower slope 6 of the actuating bar 2 presses against the upper slope 7 of the lever 13, causing the first hook 8 of the lever 13 to move away from the actuating bar 2. This separates the clamp arm 3 from the lever 13. Under the action of the torsion spring, both clamp arms 3 flip upward simultaneously, clamping the knife, allowing the defender to disarm the knife. After disarming the knife, the clamp arms 3 and lever 13 can be manually reset. For example, by pressing down on the clamp arm 3 to hook it onto the lever 13, the locking switch can be manually reset, fixing the lever 13 and clamp arm 3 together. The two clamp arms 3 are then in a reset state, retracted into the vertical groove 4.

[0025] This embodiment can also be improved in the following ways:

[0026] 1) The activation bar 2 is equipped with a downward-pressing handle (not shown in the figure) extending to the outside of the shield body 1. The downward-pressing handle can drive the activation bar 2 to move. In this way, in addition to being able to disarm the attacker when attacked by knives, clubs, etc., the attacker can also actively disarm the attacker by pressing down the handle to move the activation bar 2 downward, pressing the clamp arm 3 from the reset state to the clamping state, thereby achieving active disarming of knives, clubs, etc., and further improving the safety of the attacker.

[0027] 2) The shield body 1 is equipped with a window-breaking head 12 for breaking windows. Furthermore, the window-breaking head 12 has a through hole connected to a storage tank for storing pepper spray. The storage tank is equipped with a pressure spray switch, allowing pepper spray to be applied using the perforated window-breaking head, thus achieving a protective function.

[0028] 3) The shield body 1 is equipped with a high-intensity spotlight. When an attacker attacks, the high-intensity spotlight can be turned on to interfere with the attacker's vision.

[0029] Example 2: This example differs from Example 1 in that the first return spring 5 is arranged differently. For example... Figure 7 As shown, in this embodiment, the starting bar 2 is provided with a vertical guide hole, the shield body 1 is provided with a guide post 14 with a guide hole, the first reset spring 5 is sleeved on the guide post 14, one end of the first reset spring 5 abuts against the starting bar 2, and the other end abuts against the shield body 1, such as abutting against the bottom surface of the vertical groove in the shield body 1 or a support protrusion provided on the shield body 1.
