Description

Technical Field

[0001] This utility model relates to the field of bulletproof insert technology, and in particular to a silicon carbide ceramic bulletproof insert. Background Technology

[0002] In the modern military and security field, bulletproof inserts are a key piece of personal protective equipment, and their performance is directly related to the safety of personnel.

[0003] Traditional bulletproof plates often use a single material or a simple composite structure, which has many insurmountable defects when dealing with high-speed bullet impacts. Bulletproof plates made of a single ceramic material, such as alumina ceramic, although hard and able to effectively blunt bullets, lack toughness and are prone to brittle fracture when subjected to bullet impacts, resulting in a sharp decline in protective performance and failing to provide reliable and continuous protection for users.

[0008] The replacement component includes two grooves symmetrically formed on the outer wall of the impact-resistant layer, a connecting groove formed on the outer wall of the buffer layer, the two sides of the alloy plate being slidably connected to the inner side of the connecting groove, a connecting post being slidably connected to the inner side of the groove, and two slots symmetrically formed on the side of the surface layer away from the silicon carbide ceramic layer, with the connecting post engaging with the inner side of the slot.

[0009] In a preferred embodiment of the silicon carbide ceramic bulletproof insert of this utility model, a sliding hole is provided inside the connecting column, a slide bar is slidably connected inside the sliding hole, a limit spring is fixedly connected inside the sliding hole, the end of the limit spring away from the sliding hole is fixedly connected to the outer wall of the slide bar, and the slide bar is engaged with the slot.

[0010] As a preferred embodiment of the silicon carbide ceramic bulletproof insert of this utility model, two shock-absorbing grooves are symmetrically formed inside the buffer layer, and shock-absorbing springs are fixedly connected inside the shock-absorbing grooves. The end of the shock-absorbing spring away from the shock-absorbing groove is pressed into contact with the outer wall of the alloy plate.

[0014] (III) Beneficial Effects

[0015] This invention provides a silicon carbide ceramic bulletproof insert. It has the following beneficial effects:

[0016] 1. By setting replacement pricing, damaged alloy plates can be replaced individually. When an alloy plate is deformed or cracked due to repeated bullet impacts or severe collisions, only that specific alloy plate needs to be replaced, without discarding the entire bulletproof plate. This significantly improves resource utilization and reduces long-term usage costs. At the same time, timely replacement of damaged alloy plates ensures that the bulletproof plate always maintains good protective performance, providing users with continuous and reliable protection.

[0017] 2. By applying a boron carbide coating to the side of the impact-absorbing layer away from the buffer layer, a large amount of impact energy can be absorbed and dispersed. The energy is dispersed and consumed inside the coating, which greatly reduces the energy transferred to the silicon carbide ceramic layer and the buffer layer, reduces the pressure on the subsequent protective layer, and improves the impact resistance of the entire bulletproof plate.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8This is the first embodiment of the present invention. This embodiment provides a silicon carbide ceramic bulletproof insert, including a silicon carbide ceramic layer 1, a surface layer 2 fixedly connected to the outer wall of the silicon carbide ceramic layer 1, a buffer layer 3 fixedly connected to the side of the silicon carbide ceramic layer 1 away from the surface layer 2, an alloy plate 4 slidably connected inside the buffer layer 3, a bullet-receiving layer 5 fixedly connected to the side of the buffer layer 3 away from the silicon carbide ceramic layer 1, and a replacement component 6 for quickly replacing the alloy plate 4 provided inside the surface layer 2. The replacement component 6 includes two grooves 601 symmetrically opened on the outer wall of the bullet-receiving layer 5, a connecting groove 602 opened on the outer wall of the buffer layer 3, the alloy plate 4 being slidably connected to the inner side of the connecting groove 602 on both sides, a connecting post 603 being slidably connected to the inner side of the groove 601, and two slots 604 symmetrically opened on the side of the surface layer 2 away from the silicon carbide ceramic layer 1, with the connecting post 603 engaging with the inner side of the slot 604.

[0031] Specifically, the connecting column 603 has a sliding hole 605 inside, a sliding strip 606 is slidably connected inside the sliding hole 605, a limiting spring 607 is fixedly connected inside the sliding hole 605, the end of the limiting spring 607 away from the sliding hole 605 is fixedly connected to the outer wall of the sliding strip 606, the sliding strip 606 is engaged with the slot 604, two shock-absorbing grooves 608 are symmetrically opened inside the buffer layer 3, a shock-absorbing spring 609 is fixedly connected inside the shock-absorbing groove 608, the end of the shock-absorbing spring 609 away from the shock-absorbing groove 608 is pressed and contacted with the outer wall of the alloy plate 4, several honeycomb blocks 7 are fixedly connected at equal intervals on the side of the buffer layer 3 near the impact layer 5, the side of the impact layer 5 away from the buffer layer 3 is coated with a boron carbide coating 8, and the side of the slot 604 near the surface layer 2 is rotatably connected to a cover plate 9 by a hinge.

[0032] Furthermore, when it is found that the alloy plate 4 of the bulletproof insert needs to be replaced, first rotate the cover plate 9 around the hinge to open it and expose the slot 604. Then, use your fingers or an auxiliary tool to press the slide bar 606 to overcome the elasticity of the limiting spring 607, causing the slide bar 606 to retract into the sliding hole 605, thereby releasing the locking state between the slide bar 606 and the slot 604. Then, slowly remove the connecting post 603 from the groove 601. After the connecting post 603 is removed, the locking state between the two sides of the alloy plate 4 and the inner side of the connecting groove 602 opened on the outer wall of the buffer layer 3 is released. At this time, gently hold the edge of the damaged alloy plate 4 with your hand and slowly pull it out along the direction of the connecting groove 602. Align the prepared new alloy plate 4 with the connecting groove 602 on the buffer layer 3 and slowly insert it. When the alloy plate 4 is inserted into the appropriate position, gently press the alloy plate 4 with your hand. Make it fit tightly against the buffer layer 3, and then reinsert the connecting post 603 into the groove 601. As the connecting post 603 slides inside the groove 601, the groove 601 presses the slide bar 606 to retract into the sliding hole 605. Then, the connecting post 603 is fully inserted into the groove 601. When the connecting post 603 slides to the inside of the slot 604, the slide bar 606 pops out under the action of the limit spring 607 and engages with the slot 604. Then, the opened cover plate 9 is rotated around the hinge to cover the slot 604, and the cover plate 9 is gently pressed to make it engage tightly with the slot 604, completing the replacement operation. This significantly improves resource utilization and reduces long-term use costs. At the same time, timely replacement of the damaged alloy plate 4 ensures that the bulletproof insert always maintains good protective performance, providing users with continuous and reliable protection.

[0033] Working principle: When it is found that the alloy plate 4 of the bulletproof insert needs to be replaced, first rotate the cover plate 9 around the hinge to open it and expose the slot 604. Then, use your finger or an auxiliary tool to press the slide bar 606 to overcome the elastic force of the limit spring 607, causing the slide bar 606 to retract into the sliding hole 605, thereby releasing the locking state between the slide bar 606 and the slot 604. Then, slowly remove the connecting post 603 from the groove 601. After the connecting post 603 is removed, the locking state between the two sides of the alloy plate 4 and the inner side of the connecting groove 602 opened on the outer wall of the buffer layer 3 is released. At this time, gently hold the edge of the damaged alloy plate 4 and slowly pull it out along the direction of the connecting groove 602. Align the prepared new alloy plate 4 with the connecting groove on the buffer layer 3. 602. Slowly insert the alloy plate 4. Once the alloy plate 4 is inserted into the appropriate position, gently press the alloy plate 4 with your hand to ensure it fits tightly against the buffer layer 3. Then, reinsert the connecting post 603 into the groove 601. As the connecting post 603 slides inside the groove 601, the groove 601 presses down on the slide bar 606, causing it to retract into the sliding hole 605. Then, fully insert the connecting post 603 into the groove 601. When the connecting post 603 slides to the inside of the slot 604, the slide bar 606 pops out under the action of the limiting spring 607 and engages with the slot 604. Then, rotate the opened cover plate 9 around the hinge to cover the slot 604 and gently press the cover plate 9 to ensure it engages tightly with the slot 604, completing the replacement operation.
