Description

Technical Field

[0001] This utility model relates to the field of bulletproof plate technology, and in particular to a portable bulletproof plate with a shock-absorbing structure. Background Technology

[0002] The frequent and escalating occurrence of school shootings abroad has become a serious social problem. These incidents typically occur within educational institutions such as schools and universities, with perpetrators using firearms to indiscriminately attack teachers and students. Their suddenness, destructiveness, and the resulting large number of casualties have sparked widespread concern and panic throughout society. These events not only directly threaten the lives of students and faculty but also cast a lasting shadow of fear over the campus, an environment that should be vibrant and hopeful.

[0003] Currently, most mainstream personal bulletproof gear on the market is designed based on military or police standards, and generally suffers from problems such as large size, excessive weight, and conspicuous appearance. Traditional rigid bulletproof plates, while offering high protection levels, are inflexible due to their rigid shape, creating noticeable protrusions when placed in backpacks or folders, resulting in poor concealment and extreme inconvenience for daily carrying. While some soft bulletproof vests offer improved flexibility, their large coverage area requires wearing and removing them like clothing, making them incongruous in everyday school settings, easily attracting attention or even causing panic, and failing to meet users' core demands for "concealment" and "everyday usability."

[0004] Therefore, it is necessary to design a portable bulletproof plate with a shock-absorbing structure to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of mainstream bulletproof equipment, which are too large and heavy due to design standards, have poor concealment of hard plates, and are not suitable for daily wear due to soft vests, thus failing to meet the needs of concealment and daily use, this utility model provides a portable bulletproof plate with a shock-absorbing structure.

[0006] The technical solution is as follows: A portable bulletproof plate with a shock-absorbing structure includes a writing board, a fixed cylinder, a sliding rod, a first spring, a buffer plate, and a pull rope. The writing board is made of PE board, and the front of the writing board is coated with a micro-textured coating. Multiple fixed cylinders are embedded and fixedly connected in a rectangular array at the rear of the writing board. Each fixed cylinder is slidably connected to a sliding rod. Each sliding rod is connected to the corresponding fixed cylinder by a first spring. A buffer plate is fixedly connected to the rear of each sliding rod. The buffer plate is slidably connected to the writing board. A pull rope is fixedly connected to the top of the buffer plate. A round hole is opened at the top of the writing board.

[0007] To further explain, the writing board surface is coated with a hard, smooth paint.

[0008] To further explain, each fixed cylinder forms a damping structure with the corresponding slide rod and the first spring.

[0009] Further explanation: It also includes a connecting rod, magnets, inserts, a rotating ring, a snap-fit ​​sleeve, a second spring, and a knob. The connecting rod is embedded and rotated at the rear of the writing board. Magnets are embedded and fixedly connected to both sides of the front of the connecting rod and both sides of the rear of the writing board. Two magnets on the same side attract each other. The insert is fixedly connected to the right side of the writing board. The rotating ring is rotatably connected to the left side of the insert. The snap-fit ​​sleeve is slidably connected to the right side of the connecting rod. The insert is snapped into the snap-fit ​​sleeve. A second spring connects the connecting rod and the rotating ring. A knob is fixedly connected to the right side of the snap-fit ​​sleeve, which protrudes from the connecting rod.

[0010] To further explain, anti-slip rubber strips are fixedly installed at the bottom of the writing board and the bottom of the abutment rod.

[0011] To further explain, it also includes a pen frame, a writing pen, a locking plate, a limiting rod, a third spring, and a pull rod. The pen frame is embedded and fixedly connected to the front of the writing board, and the writing pen is placed inside the pen frame. The locking plates are slidably connected to both sides of the top of the pen frame. Both locking plates pass through the pen frame and abut against the writing pen. The limiting rods are fixedly connected to the rear of the two locking plates. The two limiting rods are slidably connected to the writing board. The third spring connects the two limiting rods to the writing board. The pull rod is fixedly connected between the front of the two limiting rods.

[0012] The beneficial effects are: 1. This utility model uses a writing board made of PE sheet as the main protective carrier, which perfectly solves the problem of the large size and weight of mainstream bulletproof equipment due to design standards. Although traditional hard plates meet the protection performance standards, their obvious outline and weight seriously affect concealment. On the other hand, soft bulletproof vests are neither comfortable nor appropriate to wear in daily office or study scenarios. The device combines the protective function with daily stationery. The hard smooth paint and micro-textured coating on the surface make it completely consistent with conventional office supplies in terms of appearance and user experience, effectively meeting the dual needs of concealment and protection in special environments and daily usability.

[0013] 2. This utility model provides excellent energy absorption performance under extreme impact conditions through a distributed shock absorption system composed of a fixed cylinder, a sliding rod, a first spring, and a buffer plate. The reciprocating motion of the entire process transforms the instantaneous strong impact into continuous buffer momentum, greatly reducing the impact force transmitted to the user's body, and providing crucial life safety protection while maintaining a portable form.

[0014] 3. This utility model achieves multi-level, coordinated energy absorption through a distributed shock absorption system composed of a fixed cylinder, sliding rods, a first spring, and a buffer plate. When an impact occurs, the impact force is evenly distributed by the buffer plate to multiple sliding rods, driving them to synchronously compress the first spring. This effectively disperses the concentrated point impact into a surface impact of multiple points. Through the independent action of each damping unit, the instantaneous high-energy impact is converted into continuous spring deformation potential energy, reducing the peak value of the impact stress and greatly weakening the impact force ultimately transmitted to the human body. Thus, while maintaining the product's lightweight and portable design, it provides dynamic protection performance and human safety far exceeding that of hard bulletproof plates of the same thickness.

Detailed Implementation

[0028] Example: A portable bulletproof plate with a shock-absorbing structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 12 As shown, the device includes a writing board 1, fixing cylinders 3, a sliding rod 4, a first spring 5, a buffer plate 6, and a pull rope 7. The writing board 1 is made of PE board, with a standard size of 253×354mm and a thickness of 6.5-8mm. The writing board 1 has achieved Level 3 protection according to GA423-2015 standards. The surface of the writing board 1 is coated with a hard, smooth paint. The front side of the writing board 1 is coated with a micro-textured coating 2. Multiple fixing cylinders 3 are embedded and fixed in a rectangular array on the rear side of the writing board 1. Each fixing cylinder 3 has a... The device is connected by sliding rods 4, and each sliding rod 4 is connected to a corresponding fixed cylinder 3 by a first spring 5. Each fixed cylinder 3, the corresponding sliding rod 4, and the first spring 5 form a damping structure. A buffer plate 6 is fixedly connected to the rear side of each sliding rod 4. The buffer plate 6 is slidably connected to the writing board 1. A pull rope 7 is fixedly connected to the top side of the buffer plate 6. The pull rope 7 is easy to take out and carry. A round hole 8 is opened on the upper side of the writing board 1, which makes it easy to hang the device on the wall or store it on a hook, improving the convenience of daily use and the neatness of storage.

[0029] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, it also includes an abutment rod 9, a magnet 10, a post 11, a rotating ring 12, a snap-fit ​​sleeve 13, a second spring 14, and a knob 15. The abutment rod 9 is embedded and rotatedly connected to the lower rear side of the writing board 1. Anti-slip rubber strips are fixedly provided on the bottom side of the writing board 1 and the bottom side of the abutment rod 9. Magnets 10 are embedded and fixedly connected to the left and right sides of the front part of the abutment rod 9 and the left and right sides of the rear part of the writing board 1. The two magnets 10 on the same side attract each other. The post 11 is fixedly connected to the right side of the writing board 1. The rotating ring 12 is rotatably connected to the left side of the post 11. The snap-fit ​​sleeve 13 is slidably connected to the right side of the abutment rod 9. The post 11 is snapped into the snap-fit ​​sleeve 13. The second spring 14 is connected between the abutment rod 9 and the rotating ring 12. The knob 15 is fixedly connected to the right end of the snap-fit ​​sleeve 13 through the abutment rod 9.

[0030] like Figure 1 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes a pen frame 16, a writing pen 17, a retaining plate 18, a limiting rod 19, a third spring 20, and a pull rod 21. The pen frame 16 is embedded and fixedly connected to the upper front part of the writing board 1. The writing pen 17 is placed inside the pen frame 16. The retaining plates 18 are slidably connected to the top left and right sides of the pen frame 16. Both retaining plates 18 are inserted into the pen frame 16 and abut against the writing pen 17. The rear ends of both retaining plates 18 are fixedly connected to the limiting rods 19. Both limiting rods 19 are slidably connected to the writing board 1. The third spring 20 is connected between the two limiting rods 19 and the writing board 1. The pull rod 21 is fixedly connected between the front sides of the two limiting rods 19.

[0031] When writing is required using this device, first pull the knob 15 to the right. The locking sleeve 13 will move away from the insert 11, and the second spring 14 will be stretched and deformed. At this time, the abutment rod 9 can be rotated by the knob 15. The rotating ring and the second spring 14 will also rotate, causing the magnet 10 on the abutment rod 9 to separate from the magnet 10 on the writing board 1 until it forms a stable angle with the writing board 1. Release the knob 15. Under the restoring force of the second spring 14, the locking sleeve 13 will slide to the left, and the insert 11 will be inserted into the locking sleeve 13, thereby supporting the entire writing board 1 on the table. At this time, the anti-slip rubber strip can effectively increase the friction with the table and prevent slippage.

[0032] The user can then pull the lever 21 upwards. The lever 21 causes the two limiting rods 19 to move upwards against the elastic force of the third spring 20, causing the locking plate 18 connected to the limiting rod 19 to slide upwards out of the pen frame 16, thereby releasing the restriction on the writing pen 17. At this time, the writing pen 17 can be taken out of the pen frame 16 for writing. During the writing process, the micro-textured coating 2 or the hard smooth paint surface can provide a suitable writing surface and effectively prevent the paper from slipping. After use, the writing pen 17 is put back into the pen frame 16, the lever 21 is released, the third spring 20 pushes the limiting rod 19 downwards to reset, thereby causing the locking plate 18 to move downwards and lock the writing pen 17, completing the fixation.

[0033] In the event of a sudden attack, the user must quickly switch the device to protective mode. First, turn knob 15 forward. Knob 15 moves the locking sleeve 13 to the right and stretches the second spring 14, causing the locking sleeve 13 to separate from the insert 11. The abutment rod 9 rotates back to its original position, and the magnet 10 on it re-attracts to the magnet 10 on the writing pad 1, causing the abutment rod 9 to adhere tightly to the back of the writing pad 1, restoring its portable state. Release knob 15, and the insert 11 snaps into the locking sleeve 13. The user can immediately hold the device with the side containing the buffer plate 6 facing the source of the threat. Upon impact from a bullet or shrapnel, the impact force first acts on the buffer plate 6, and the buffer plate 6, after being subjected to the force... The system moves forward, pushing all the slide rods 4 to slide inward along their respective fixed cylinders 3. During the sliding process of the slide rods 4, all the first springs 5 ​​are compressed. Due to the damping structure formed by the fixed cylinders 3, slide rods 4, and first springs 5, this process can effectively absorb and disperse the huge impact kinetic energy, converting the instantaneous strong impact into continuous buffer momentum. After the first springs 5 ​​are compressed to their limit, their stored elastic potential energy begins to be released, pushing all the slide rods 4 to slide backward, which in turn drives the buffer plate 6 to move backward and reset. The entire shock absorption system greatly weakens the impact force transmitted to the user's body through such repeated compression and rebound, thereby providing crucial life safety protection.
