Description

Technical Field

[0001] This utility model relates to the field of military equipment technology, specifically a military defensive plate. Background Technology

[0002] Military defensive panels are specialized equipment that provide direct protection for individual soldiers or tactical squads in military scenarios. Their core function is to act as a "mobile defensive barrier," reducing the risk of casualties by resisting high-frequency threats on the battlefield (such as bullets, explosive fragments, shock waves, etc.) while creating a safe window for tactical operations (such as advance, cover, and rescue).

[0003] The inside of a military protective plate (the side facing the human body) is equipped with straps and handles. When operating it, the soldier needs to pass his forearm through the straps and hold the handles to operate the plate. The forearm and the straps are in contact. The key to this step is to make the forearm the "main force point" of the protective plate and use the strength of the torso to support the weight of the protective plate. Since the straps are only connected to the protective plate through two moving points, they will rotate around the fixed point when force is applied, causing the straps to shift on the forearm and slip, making it difficult for the soldier to operate the protective plate smoothly. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a military defensive plate that solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a military defensive plate, including a shield, a base block fixedly disposed on the inner side of the shield, and an L-shaped handle. The L-shaped handle is located on one side of the base block in the horizontal direction. An I-shaped slider is slidably connected to the side of the base block away from the shield. A U-shaped limiting rod is fixedly connected to the side of the I-shaped slider away from the base block.

[0008] The base block has a horizontally arranged groove on the side away from the shield. One end of the I-shaped slider is slidably disposed inside the groove. The I-shaped slider can move horizontally along the groove to adjust the position of the U-shaped limit rod.

[0009] Preferably, the surface of the base block has a plurality of screw holes I arranged in two rows, and the surface of the I-shaped slider has two symmetrically distributed screw holes II. The I-shaped slider is fixedly installed on the base block by bolts, and the threaded end of the bolts is inserted into screw holes II and screw holes I in sequence.

[0010] Preferably, an elastic pad is fixedly connected to the side of the I-shaped slider away from the base block, and the elastic pad is located inside the U-shaped limiting rod.

[0011] Preferably, the screw holes are distributed on the upper and lower sides of the slide groove, and multiple screw holes in the same row are linearly and equidistantly distributed.

[0012] Preferably, a frame is fixedly installed on the shield, and an observation window is fixedly embedded inside the frame. The frame is located above the base block and the L-shaped handle.

[0013] Preferably, the L-shaped handle has a circular cross-section, and both the L-shaped handle and the U-shaped limiting rod are provided with protective sleeves made of fluororubber.

[0014] (III) Beneficial Effects

[0015] This utility model provides a military defensive plate with the following beneficial effects:

[0016] 1. In this utility model, by setting a movable I-shaped slider on the surface of the base block, the position of the U-shaped limiting rod can be adjusted, and the position is locked by bolts, so that the U-shaped limiting rod is adjusted to the soldier's elbow, forming a limiting structure (because the U-shaped limiting rod is fixedly connected to the shield, it prevents the defensive plate from sliding downward due to gravity and avoids slipping off from the wrist); on the other hand, the wrap-around structure can increase the contact area between the limiting rod and the forearm, disperse local pressure, and greatly improve static friction, reducing the possibility of the forearm slipping on the U-shaped limiting rod, ensuring that the soldier can operate the defensive plate flexibly.

[0017] 2. In this utility model, compared with the traditional straps such as Velcro and buckles which are easy to loosen, the mechanical locking of the bolt has the advantages of high rigidity, vibration resistance and impact resistance: after locking, the I-shaped slider forms a rigid connection with the base block and will not shift due to the continuous tensile force generated by the weight of the defense plate itself.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a military defense plate, including a shield 1, a base block 4 fixedly installed on the inner side of the shield 1 and an L-shaped handle 9. The L-shaped handle 9 is located on one side of the base block 4 in the horizontal direction. An I-shaped slider 5 is slidably connected to the side of the base block 4 away from the shield 1. A U-shaped limiting rod 6 is fixedly connected to the side of the I-shaped slider 5 away from the base block 4.

[0025] When using this device, the operator's forearm needs to pass through the U-shaped limiting rod 6, and then the hand holds the L-shaped handle 9. The U-shaped limiting rod 6 is located near the elbow crease, so that force can be applied from both the elbow crease and the hand to carry and operate the shield 1. The U-shaped limiting rod bears the main weight of the defensive plate (transmitted to the torso through the elbow crease), and the L-shaped handle 9 is mainly responsible for fine-tuning the angle of the shield 1 (such as raising up and down, turning left and right) to avoid fatigue caused by the arm bearing the weight alone.

[0026] Reference Figure 4 The base block 4 has a horizontally arranged groove 401 on the side away from the shield 1. One end of the I-shaped slider 5 is slidably disposed inside the groove 401. The I-shaped slider 5 can move horizontally along the groove 401 to adjust the position of the U-shaped limit rod 6. The groove 401 here is a T-shaped structure, which is adapted to the I-shaped slider 5, so that the I-shaped slider 5 can move horizontally in a straight line along the groove 401.

[0027] By setting a movable I-shaped slider 5 on the surface of the base block 4, the position of the U-shaped limiting rod 6 can be adjusted and locked, so that the U-shaped limiting rod 6 is adjusted to the soldier's elbow crease to form a limiting structure (because the U-shaped limiting rod 6 is fixedly connected to the shield 1, it prevents the defensive plate from sliding downward due to gravity and avoids slipping off from the wrist); on the other hand, the wrap-around structure can increase the contact area between the U-shaped limiting rod 6 and the forearm, disperse local pressure, and greatly improve static friction, reducing the possibility of slippage between the forearm and the U-shaped limiting rod 6, thereby ensuring that the soldier can operate the defensive plate flexibly.

[0028] Reference Figure 3 and Figure 4The surface of the base block 4 has multiple screw holes 402 arranged in two rows. The surface of the I-shaped slider 5 has two symmetrically distributed screw holes 501. The I-shaped slider 5 is fixedly installed on the base block 4 by bolts 7. The threaded end of the bolts 7 is inserted into the screw holes 501 and 402 in sequence.

[0029] Since the forearm length of each soldier may vary, the position of the I-shaped slider 5 is locked by adjusting the I-shaped slider 5 to a suitable position on the base block 4 so that the screw hole 2 501 corresponds to the screw hole 1 402. Then, the threaded end of the bolt 7 is screwed into the screw hole 2 501 and the screw hole 1 402.

[0030] Reference Figure 3 and Figure 4 An elastic pad 8 is fixedly connected to the side of the I-shaped slider 5 away from the base block 4, and the elastic pad 8 is located inside the U-shaped limit rod 6.

[0031] Fluororubber foam has excellent weather resistance and durability; it can withstand extreme temperatures of -20℃ to 150℃ (covering combat environments such as high-temperature deserts and low-temperature plateaus), and is resistant to sweat, rain, and tactical oil stains, making it suitable for long-term use; it is not prone to cracking, deformation, or loss of adhesion.

[0032] It provides sufficient elasticity (fitting the muscle curves of different soldiers' forearms to avoid localized pressure) while maintaining a certain level of support; when the protective plate is impacted by a bullet, it can buffer the transmission of vibration to the forearm, and at the same time, it will not cause the U-shaped limiting rod 6 to "lose its limiting function" due to excessive deformation.

[0033] Reference Figure 3 and Figure 4 Screw holes 402 are distributed on the upper and lower sides of the slide groove 401, and multiple screw holes 402 in the same row are linearly and equally spaced.

[0034] Two bolts 7 are used to lock the I-shaped slider 5 from both sides. Compared with single-sided locking, the locking force on the I-shaped slider 5 is more uniform, which prevents the I-shaped slider 5 from tilting or shifting in the slide groove 401, thereby improving the stability and reliability of locking.

[0035] Two bolts 7 lock the I-shaped slider 5 from both sides, which is equivalent to increasing the contact point and friction between the I-shaped slider 5 and the groove 401, enabling it to withstand greater external force and load. For example, when the shield 1 is attacked by the enemy, the I-shaped slider 5 locked on both sides can better fix the U-shaped limit rod 6, enabling it to withstand greater impact and ensure the safety of the soldiers.

[0036] Reference Figure 1 and Figure 2A frame 2 is fixedly installed on the shield 1, and an observation window 3 is fixedly embedded inside the frame 2. The frame 2 is located above the base block 4 and the L-shaped handle 9.

[0037] The observation window 3 is made of bulletproof glass (such as alumina composite bulletproof glass, which can withstand 9mm pistol bullets and fragment impacts). Soldiers can keep track of the dynamics of the battlefield in front of them in real time (such as the location of enemy fire points, the advance route of teammates, and the distribution of obstacles) without removing the shield 1, which greatly reduces the risk of casualties caused by "blind defense".

[0038] Shield 1 is made of ultra-high molecular weight polyethylene (UHMWPE), with a density of only about 0.97 g / cm³, making it extremely lightweight and significantly reducing the burden on individual soldiers. At the same weight, its ballistic protection efficiency is slightly better than aramid fiber, effectively resisting pistol bullets (such as 9mm Parabellum rounds), rifle bullets (such as 5.56mm bullets), and explosive fragments (such as hand grenades and artillery shell shrapnel). Upon bullet impact, UHMWPE absorbs kinetic energy through "tensile fracture + inter-fiber friction," preventing bullet penetration. Simultaneously, Shield 1 exhibits minimal "dentation deformation" (reducing secondary impact damage to the soldier's forearm and torso).

[0039] Reference Figure 3 and Figure 4 The L-shaped handle 9 has a circular cross-section, and both the L-shaped handle 9 and the U-shaped limit rod 6 are equipped with protective sleeves made of fluororubber.

[0040] Even when exposed to sweat, rain (humid environment) or dust (outdoor scene), it can still maintain stable friction; prevent the L-shaped handle 9 from slipping when hands are sweaty, or prevent the forearm from shifting when it rests on the U-shaped limiting rod 6. In addition, the area formed by the U-shaped limiting rod 6 and the I-shaped slider 5 is adapted to the width of the forearm as much as possible, and the elasticity of the fluororubber material can compensate for the gap of the forearm, thus ensuring that the shield 1 remains stable when raising the shield for defense and moving for adjustment.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
