Description

Technical Field

[0001] The invention relates to the technical field of military materials, in particular to a tactical bulletproof shield. Background Art

[0002] Tactical bulletproof shields are a type of protective equipment mainly used by the military, police and other law enforcement agencies when performing dangerous tasks. They are usually made of high-strength bulletproof materials such as Kevlar fiber and special steel. They can effectively resist shooting from various firearms and ammunition. In dangerous scenarios such as gun battles and conflicts, they provide users with protection for important parts of the body and reduce the risk of injury.

[0003] In the use of tactical bulletproof shields, since most of them are built in a rectangular or arc shape, although they have a strong bulletproof effect, they can only block damage from the front, and a few can block damage from the side. However, since they are mainly folding units, this method can protect the side, but the folding unit is complicated to operate, and the folding unit is easily deformed when damaged, resulting in the inability to fold. For this reason, we propose a tactical bulletproof shield. Summary of the invention

[0004] The purpose of the present invention is to provide a tactical bulletproof shield to solve the problem raised in the above background technology that in the use of tactical bulletproof shields, most of them are basically built in a rectangular or arc shape. Although they have a strong bulletproof effect, they can only block damage from the front, and a few can block damage from the side. However, since the folding unit is mainly used, this method can protect the side, but the folding unit is complicated to operate, and the folding unit is easily deformed when damaged, resulting in the problem that it cannot be folded. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tactical bulletproof shield, comprising a main bulletproof shield, a secondary bulletproof shield assembly is arranged inside the main bulletproof shield, a baffle is movably connected to the side surface of the secondary bulletproof shield assembly, a protrusion is fixedly connected to one side of the baffle, a fixing plate is fixedly connected to one side of the protrusion, a first supporting column is fixedly connected to the side surface of the main bulletproof shield, a rotating shaft is movably connected to the top of the main bulletproof shield, an observation port is provided on the side surface of the main bulletproof shield, a bulletproof glass placement groove is provided inside the observation port, a sliding groove is provided inside the main bulletproof shield, a limiting groove is provided inside the sliding groove, a secondary shield is arranged inside the main bulletproof shield, a fixing ring is fixedly connected to the bottom of the secondary shield, a limiting ring is fixedly connected to the bottom of the fixing ring, and the secondary shield The side surface of the shield is fixedly connected with a first armrest. By arranging a secondary bulletproof shield assembly inside the main bulletproof shield, the overall protection capability of the shield is significantly improved. The secondary bulletproof shield assembly and the baffle thereon can provide an additional layer of protection when necessary, effectively resisting attacks from different directions. The main bulletproof shield is provided with an observation port and a built-in bulletproof glass placement slot, allowing the user to observe the external situation without exposing himself, thereby improving battlefield perception and safety. The design of the fixing ring and the limiting ring ensures the stability of the secondary shield in the sliding groove, preventing it from accidentally moving or falling off during combat. At the same time, the setting of the first armrest provides the user with a stable gripping point, enhancing the stability and safety when holding the shield. In addition, the design of the sliding groove and the limiting groove of the secondary shield makes its adjustment process smooth and accurate, thereby improving the convenience and efficiency of operation.

[0005] Further preferably, a fourth slot is provided on the side surface of the secondary shield, a second spring is fixedly connected inside the fourth slot, a limiting block is fixedly connected to the top of the second spring, and the limiting block, through the connection between the second spring and the fourth slot, can provide a certain buffering and resetting effect when subjected to external force impact. This design enables the secondary shield to remain in its original position more stably when subjected to an attack, and is not easily displaced or dropped off due to impact, thereby enhancing the stability of the entire shield system. In some cases, the user may need to adjust the position of the secondary shield according to tactical requirements. The design of the fourth slot and the limiting block makes such adjustment simple and quick. At the same time, since the limiting block is subjected to the elastic force of the second spring, it can automatically remain in an appropriate position in the slot, which is convenient for the user to quickly fix the secondary shield without the need for additional fixing devices or operations.

[0006] Further preferably, the bottom end of the main bulletproof shield is fixedly connected to a second supporting column, the bottom end of the second supporting column is fixedly connected to a first horizontal plate, the top of the first horizontal plate is fixedly connected to a first circular ring, the top of the first circular ring is movably connected to a nut, the internal thread of the nut is connected to a threaded rod, the bottom of the first horizontal plate is fixedly connected to a second circular ring, the bottom end of the second circular ring is movably connected to the second horizontal plate, both sides of the second horizontal plate are respectively fixedly connected to vertical plates, one side of the vertical plate is movably connected to a roller, the inside of the roller is movably connected to a central axis, and the rollers are movably connected to the vertical plates fixedly connected on both sides of the second horizontal plate, and these rollers can rotate freely through the central axis, so that the entire shield system can roll easily on the ground. This design greatly improves the mobility and portability of the shield, allowing the user to quickly move to cope with changes on the battlefield.

[0007] Further preferably, the fixing ring is movably connected to the inside of the sliding groove, and the limiting ring is movably connected to the inside of the limiting groove. By combining the design of the sliding groove and the limiting groove, the user can accurately control the position of the secondary shield. The secondary shield moves under the guidance of the sliding groove and the limiting groove, so that it can quickly cover the area that needs protection. This ability of rapid response and precise adjustment helps to improve the overall protective performance of the shield and provide more comprehensive protection for the user.

[0008] Further preferably, a second card slot is opened inside the fixing plate, a third card slot is opened inside the fixing plate, and the second card slot is opened inside the third card slot. By opening card slots of different sizes and positions inside the fixing plate, various accessories can be flexibly installed and adjusted to meet the usage requirements in different tactical scenarios.

[0009] Further preferably, a first spring is fixedly connected inside the third slot, and a fixing block is fixedly connected to the top of the first spring, and the first spring provides elastic support for the fixing block, so that the fixing block can automatically return to its original position after being acted upon by an external force. This automatic reset function is particularly important when accessories need to be frequently adjusted or replaced, and it can reduce manual intervention and improve operating efficiency.

[0010] Further preferably, the side surface of the main bulletproof shield is fixedly connected with a sound amplification port, the other side surface of the main bulletproof shield is fixedly connected with a sound collection port, and the inner side of the main bulletproof shield is fixedly connected with a second handrail. The design of the sound amplification port and the sound collection port makes the shield not only have a protective function, but also have a communication auxiliary function. In a combat environment, team members need to maintain close communication to coordinate actions. The sound amplification port can amplify the user's voice and transmit it outward, while the sound collection port can more effectively collect external sounds, helping the user to hear the instructions of comrades or the movements of the enemy more clearly.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the secondary bulletproof shield assembly is arranged inside the main bulletproof shield, so that the overall protection capability of the shield is significantly improved. The secondary bulletproof shield assembly and the baffle thereon can provide an additional protection layer when necessary, and effectively resist attacks from different directions. The main bulletproof shield is provided with an observation port and a built-in bulletproof glass placement groove, so that the user can observe the external situation without exposing himself, thereby improving the battlefield perception capability and safety. The design of the fixing ring and the limiting ring ensures the stability of the secondary shield in the sliding groove, and prevents the secondary shield from accidental movement or falling off during combat. At the same time, the setting of the first armrest provides a stable gripping point for the user, and enhances the stability and safety when holding the shield. In addition, the design of the sliding groove and the limiting groove of the secondary shield makes its adjustment process smooth and accurate, thereby improving the convenience and efficiency of operation.

[0014] In the present invention, the connection between the second spring and the fourth slot can provide a certain buffering and restoring effect when subjected to external force impact. This design enables the secondary shield to be more stably maintained in the original position when subjected to attack, and is not easily displaced or dropped due to impact, thereby enhancing the stability of the entire shield system. In some cases, the user may need to adjust the position of the secondary shield according to tactical requirements. The design of the fourth slot and the limiting block makes such adjustment simple and quick. At the same time, since the limiting block is subjected to the elastic force of the second spring, it can automatically maintain the appropriate position in the slot, which is convenient for the user to quickly fix the secondary shield without the need for additional fixing devices or operations. The fixing on both sides of the second horizontal plate Rollers are movably connected to the fixed vertical plates. These rollers can rotate freely through the central axis, so that the entire shield system can roll easily on the ground. This design greatly improves the mobility and portability of the shield, allowing users to quickly move positions to respond to battlefield changes. By combining the design of the sliding groove and the limit groove, the user can accurately control the position of the secondary shield. The secondary shield moves under the guidance of the sliding groove and the limit groove, so that it can quickly cover the area that needs protection. This ability of rapid response and precise adjustment helps to improve the overall protection performance of the shield and provide users with more comprehensive protection, so that the fixed block can automatically reset to the original position after being subjected to external force. This automatic reset function is particularly important when frequent adjustments or replacements of accessories are required. It can reduce manual intervention and improve operational efficiency.
