Description

Technical Field

[0001] This utility model relates to the field of protective shield technology, and in particular to a security protective shield. Background Technology

[0002] Security shields are defensive equipment specifically designed to protect security personnel from physical attacks. They are widely used in crowd control, riot control operations, and emergency response.

[0003] In public places such as banks and schools, security shields are often installed at guard posts to prevent emergencies. However, the current size of these shields cannot be changed, meaning that in certain situations, the shield's protective area cannot be increased to ensure the user's safety. Furthermore, since the shields are used by multiple people, and each user has a different dominant hand, the handles on the shields are not adjustable. This forces users with different dominant hands to choose the appropriate shield, which is inconvenient. Therefore, we urgently need a security shield to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the grip not being adjustable and the protective surface not being able to be increased in the existing technology, and to propose a security shield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A security shield includes a shield body and a viewing window on the shield body. It also includes: an expansion plate one; slide rail interfaces are fixedly installed on both sides of the shield body; the expansion plate one is slidably mounted on at least one slide rail interface; and an expansion plate two is inserted into the top of the shield body. When the expansion plate two is installed, the protective area above the shield body increases. A horizontal plate connected to the shield body can be rotated...

[0007] Straps and handles are fixedly installed on the horizontal plate. When the horizontal plate rotates, the positions of the handles and straps are reversed.

[0008] To limit the position of the expansion plate, preferably, a buckle is hinged on the slide rail interface, and the buckle locks the expansion plate after it is installed.

[0009] In order to allow the grip position to be interchanged, preferably, a telescopic rod is rotatably connected to the protective shield body, and the movable end of the telescopic rod is fixedly installed with the horizontal plate.

[0010] To limit the rotation of the horizontal plate, preferably, limit rods are symmetrically installed on the horizontal plate, and the limit rods are inserted into the upper limit groove of the protective shield body.

[0011] To further enhance the functionality of the protective shield, an extension frame is symmetrically mounted on the protective shield. The extension frame is used to add external devices to the protective shield.

[0012] To prevent the viewing window from cracking, preferably, the viewing window is made of explosion-proof polyurethane glass.

[0013] Compared with the prior art, this utility model provides a security shield with the following beneficial effects:

[0014] 1. When it is necessary to increase the protective area of ​​the shield body, two expansion plates are inserted into the slide rail interface and the expansion plates are limited by the buckles. The second expansion plate is then inserted into the top of the shield body, thereby increasing the protective area on both sides and the top of the shield body and further improving the safety protection level for the user.

[0015] 2. When the user's dominant hand is left-handed, the horizontal plate is pulled outward using the movable end of the telescopic rod. The limiting rod is pulled out from the limiting groove two, releasing the rotation restriction of the horizontal plate. After the horizontal plate is rotated so that the positions of the strap and the handle are reversed, the horizontal plate is pushed back using the telescopic rod. The limiting rod and the limiting groove two are re-engaged to limit the horizontal plate. This allows it to be adapted to users with different dominant hands, improving the applicability of the shield.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model improves the applicability and protective performance of the protective shield body. Attached Figure Description

[0025] Reference Figures 1-5 A security shield includes a shield body 1, on which extension frames 14 are symmetrically mounted. The extension frames 14 are used to add peripherals to the shield body 1.

[0026] The extension bracket 14 is used to install peripherals such as flashlights and warning lights, thereby improving the practicality of the protective shield body 1.

[0027] The protective shield body 1 has a viewing window 2 made of explosion-proof polyurethane glass. It also includes an extension plate 4. The protective shield body 1 has slide rail interfaces 3 fixedly installed on both sides. The extension plate 4 is slidably installed on at least one slide rail interface 3. When the extension plate 4 is installed, the protective area on both sides of the protective shield body 1 increases. The slide rail interface 3 is hinged with a buckle 9. When the extension plate 4 is installed, the buckle 9 locks the extension plate 4.

[0028] An extension plate 2 5 is inserted into the top of the protective shield body 1. A limiting groove 10 is symmetrically formed on the protective shield body 1, and the extension plate 2 5 is inserted into the limiting groove 10. When the extension plate 2 5 is installed, the protective area above the protective shield body 1 increases.

[0029] When it is necessary to increase the protective area of ​​the shield body 1, two expansion plates 4 are inserted into the slide rail interface 3, and the expansion plates 4 are limited by the buckle 9. The expansion plate 5 is then inserted into the top of the shield body 1, thereby increasing the protective area on both sides and the top of the shield body 1 and further improving the safety protection level for the user.

[0030] A horizontal plate 6 is rotatably connected to the shield body 1. Straps 7 and handles 8 are fixedly installed on the horizontal plate 6. When the horizontal plate 6 rotates, the handles 8 and straps 7 are swapped. A telescopic rod 11 is rotatably connected to the shield body 1, and the movable end of the telescopic rod 11 is fixedly installed to the horizontal plate 6. Limiting rods 12 are symmetrically installed on the horizontal plate 6, and the limiting rods 12 are inserted into the upper limit groove 13 of the shield body 1.

[0031] When the user's dominant hand is left-handed, the horizontal plate 6 is pulled outward using the movable end of the telescopic rod 11. The limiting rod 12 is pulled out from the limiting groove 13, releasing the rotation restriction of the horizontal plate 6. The horizontal plate 6 is then rotated 180 degrees so that the positions of the strap 7 and the handle 8 are reversed. The horizontal plate 6 is then pushed back using the telescopic rod 11, and the limiting rod 12 and the limiting groove 13 are reconnected to limit the horizontal plate 6. It should be noted that the limiting groove 13 is equipped with damping to increase the resistance when the limiting rod 12 moves.

[0032] In this utility model, when needed, the operator inserts two expansion plates 4 into the slide rail interface 3 and uses the buckle 9 to limit the expansion plate 4, inserts the second expansion plate 5 into the top of the protective shield body 1, and installs the required flashlight, warning light and other peripherals on the expansion frame 14 to complete the expansion installation of the protective shield body 1, thereby increasing the protective area of ​​the protective shield body 1 and further improving the safety protection level for the user.

[0033] When the user's dominant hand is left-handed, the horizontal plate 6 is pulled outward using the movable end of the telescopic rod 11. The limiting rod 12 is pulled out from the limiting groove 13, releasing the rotation restriction of the horizontal plate 6. The horizontal plate 6 is then rotated 180 degrees, so that the positions of the strap 7 and the handle 8 are swapped. The horizontal plate 6 is then pushed back using the telescopic rod 11, and the limiting rod 12 and the limiting groove 13 are re-inserted to limit the horizontal plate 6, making it easier for left-handed users to use. When the next user's dominant hand is right-handed, the above operation is repeated to complete the swapping of the positions of the strap 7 and the handle 8.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
