Description

Technical Field

[0001] This invention relates to the field of bulletproof and riot shield technology, and in particular to a portable multi-functional bulletproof and riot shield. Background Technology

[0002] A bulletproof shield is a common piece of police and military equipment used to stop bullets. Traditional bulletproof shields are generally rectangular with a curved shape and a fixed handle at the back for easy gripping. They are wider than an adult male's body and reach chest height. Large and heavy, they are raised in front of the user to cover the head and body, providing comprehensive protection. They are typically prepared in advance by police or military personnel for dangerous situations and are not suitable for use in everyday life or work emergencies involving violence. A bulletproof briefcase is a newer type of bulletproof shield, resembling a briefcase in shape and appearance. In a dangerous emergency, it can quickly unfold into a bulletproof shield. While convenient to carry, bulletproof briefcases only offer bulletproof protection and still require advance preparation. They are only suitable for situations where danger is anticipated and are not suitable for use in everyday life or work emergencies involving violence. However, violent shootings occur frequently in daily life and work, leaving people without bulletproof or riot control equipment unable to protect themselves in sudden encounters with violence. Therefore, it is necessary to design a bulletproof and riot shield that can be used normally as a daily living and working item, and has bulletproof and riot protection functions in the event of a sudden violent incident. Summary of the Invention

[0003] To address the issues of large size, heavy weight, inconvenience in use, and the need for prior preparation of the aforementioned bulletproof shields, this invention proposes a portable, multi-functional bulletproof and riot control shield to improve the shield's functionality and ease of use.

[0004] To achieve the above objectives, the present invention provides a portable multi-functional bulletproof and riot control shield, comprising a shield body, characterized in that the shield body is flat, the back of the shield body is provided with a handle that can rotate relative to the shield body, the front of the shield body is provided with a folder for holding paper placed on the front of the shield body, and the material of the shield body is ultra-high molecular weight polyethylene (UHMWPE), aramid, or polycarbonate (PC).

[0005] This invention can be used as a writing pad in daily work and life. The shield body is made of bulletproof ultra-high molecular weight polyethylene, aramid, or riot-proof polyethylene carbonate. In case of sudden danger, holding the handle on the back of the shield body allows for easy access as a bulletproof or riot-proof protective tool to protect vital areas such as the head and to retaliate. The handle can rotate relative to the shield body, making it convenient for the user to grip when used as a bulletproof or riot-proof tool. When not in use, it can be folded up and stored in a bag for easy carrying and storage. This invention integrates bulletproof and riot-proof functions with the function of a writing pad, is small and lightweight, and is convenient to use and carry, providing bulletproof and riot-proof protection anytime, anywhere in daily work and life.

[0007] The present invention will now be described in further detail with reference to the accompanying drawings. Detailed Implementation

[0008] See Figures 1 to 3The portable multi-functional bulletproof and riot shield includes a shield body 1, a folder 2, and a handle 3. The shield body 1 is generally rectangular and thin, with a thickness of 3cm to 10cm. Its cross-section is similar in shape to A4 or A3 paper, but smaller or larger, preferably 20% smaller or larger. The shield body 1, similar in shape to A4 paper, can hold A4 paper or smaller paper; similar in shape to A3 paper, it can hold A3, A4, or smaller paper. The paper can be laid flat on the shield body for support, facilitating writing. The folder 2 is located on the front of the shield body 1, used to hold paper placed on the front. The folder 2 can be positioned near the upper, left, or right edge of the shield body 1, preferably the upper position shown in this embodiment. Folder 2 can adopt the folder structure used in existing writing pads, as long as it is easy to clamp and open to remove the paper. Open folder 2, place the paper on the front of the shield body, then close folder 2 to clamp the paper. To remove the paper, open folder 2 again. This invention can be used as a writing pad in daily life and work.

[0009] The shield body 1 is made of ultra-high molecular weight polyethylene (UHMWPE), aramid, or polyethylene carbonate (PC). UHMWPE has an excellent strength-to-weight ratio, low density, and higher elongation at break than carbon fiber and aramid, exhibiting good flexibility. Shield body 1 made of UHMWPE has excellent ballistic performance and is lightweight. Aramid is a widely used bulletproof material due to its high strength, high modulus, and low density. Polyethylene carbonate has excellent impact resistance; its impact strength is 250-300 times that of ordinary glass and twice that of tempered glass, while its weight is about half that of glass of the same thickness. It effectively resists external impacts and reduces damage caused by impacts. Shield body 1 made of polyethylene carbonate has excellent riot protection performance and is lightweight.

[0010] See Figure 3 and Figure 4 The handle 3 is located in the middle of the back of the shield body 1 and can rotate relative to the shield body 1. See also Figure 2The shield body 1 has four countersunk holes 11 on its front side, which penetrate the shield body along its thickness. The handle base 4 is located in the center of the back of the shield body 1 and has four through holes, each corresponding to one of the countersunk holes 11. Screws 6 pass through the countersunk holes 11 and the through holes on the handle base 4 from the front of the shield body 1 and connect with nuts 7, securing the handle base 4 to the shield body 1. The handle base can also be attached to the shield body 1 using adhesive or other methods. A cover layer 5 is applied to the front of the shield body to cover the countersunk holes 11 and screws 6, ensuring a flat surface for writing and enhancing the product's aesthetics.

[0011] See Figure 4 A spring and steel ball 8 are mounted on the handle base 4. The handle includes a spring and a steel ball, with one end of the spring connected to the handle base 4 and the other end connected to the steel ball. The handle 3 is rotatably mounted on the handle base 4 via a pivot 31. Figure 4 The folding position shown and Figure 5 The handle 3 can rotate back and forth between the shown open positions. A positioning groove 32 is provided on the handle 3. When the handle 3 is rotated to the folded position close to the shield body (e.g., ...), Figure 3 and Figure 4 (As shown), the steel ball is inserted into the positioning groove 31, fixing the handle 3 in this position. Folding the handle makes it easy to put the portable multi-functional bulletproof and riot shield into a backpack or briefcase, making it convenient to store and carry. In case of sudden danger and the need for bulletproof and riot protection, manually rotate the handle 3 to turn it to... Figure 5 With the shield in the open position shown, holding the handle and lifting the shield body allows it to be used as a bulletproof or riot control tool.

[0012] This invention can be used as a writing pad in daily work and life. The shield body is made of bulletproof ultra-high molecular weight polyethylene, aramid, or riot-proof polyethylene carbonate. In case of sudden danger, holding the handle on the back of the shield body allows for easy access as a bulletproof or riot-proof protective tool to protect vital areas such as the head and to retaliate. The handle can rotate relative to the shield body, making it convenient for the user to grip when used as a bulletproof or riot-proof tool. When not in use, it can be folded up and stored in a bag for easy carrying and storage. This invention integrates bulletproof and riot-proof functions with the function of a writing pad, is small and lightweight, and is convenient to use and carry, providing bulletproof and riot-proof protection anytime, anywhere in daily work and life.
