Description

Technical Field

[0001] This utility model relates to the field of security door technology, and in particular to a multi-level security door with bulletproof capabilities. Background Technology

[0002] As society develops, people have higher and higher requirements for building safety, so security doors with bulletproof performance are becoming more and more common.

[0003] However, traditional security doors have certain technical limitations in terms of bulletproof performance and maintainability. For example, traditional bulletproof doors usually use fixed bulletproof layers that cannot be disassembled or replaced individually. Once a layer ages or is damaged, the entire door needs to be replaced, increasing maintenance costs and complexity. In addition, these doors mostly use a single bulletproof structure, making it difficult to flexibly adjust the bulletproof level according to different environments or security needs. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional security doors being unable to be disassembled or replaced individually and unable to flexibly adjust their bulletproof level, and to provide a multi-level security door with bulletproof levels.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a multi-level anti-theft door with bulletproof capabilities, including...

[0007] Door frame;

[0008] The door body is located within a door frame. The door body includes a shell, within which a central frame is detachably connected. A bulletproof module is detachably installed within the central frame. The bulletproof module consists of multiple unit bulletproof modules arranged in a layered structure and tightly connected to each other. A rear cover is provided on the shell, and a clamping and buffering mechanism is provided between the rear cover and the bulletproof module to clamp and fix the bulletproof module within the shell.

[0009] Furthermore, the central frame is provided with multiple adjustment and fixing components for fixing multiple bulletproof modules into the central frame.

[0010] Furthermore, the adjusting fastener includes an angle iron plate, which is composed of a first plate and a second plate perpendicular to each other. Two adjacent first plates are threadedly connected, and the second plate is also threadedly connected to the central frame.

[0011] Furthermore, the first plates located on the same plane are connected by connecting strips.

[0012] Furthermore, a metal mesh is provided between two adjacent bulletproof modules, and the bulletproof modules are tightly connected by an adhesive.

[0013] Furthermore, the clamping and buffering mechanism includes a clamping plate, which is connected to the rear cover by a spring.

[0014] Furthermore, the multiple bulletproof modules are arranged sequentially from front to back to form a primary bulletproof layer, a secondary bulletproof layer, and a tertiary buffer layer; the primary bulletproof layer is made of alumina or silicon carbide; the secondary bulletproof layer is made of carbon fiber reinforced plastic or glass fiber reinforced plastic; and the tertiary buffer layer is made of high-density foam plastic or rubber.

[0015] The beneficial effects of this utility model are:

[0016] 1. By adopting a multi-layered bulletproof module design, each layer can absorb and disperse the kinetic energy of the bullet layer by layer, significantly improving the overall bulletproof performance. In addition, the metal mesh and adhesive between adjacent bulletproof modules further enhance the integrity of the structure and its impact resistance.

[0017] 2. By setting up a detachable connection method, modules with different bulletproof levels can be selected and replaced according to actual needs, improving the flexibility and adaptability of the security door. The detachability of individual modules not only avoids the high cost of replacing the whole unit, but also allows the bulletproof level to be adjusted according to actual needs.

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0026] Example 1

[0027] like Figures 1-5 As shown,

[0028] A bulletproof, multi-level security door, including a door frame 1;

[0029] It also includes a door body 2, which is located inside the door frame 1. Specifically, one end of the door body 2 is hinged to the door frame 1, and the other end is locked to the door frame 1 via a door lock 7. Further, the door body 2 includes a housing 21, within which a central layer frame 22 is provided. The central layer frame 22 is detachably connected to the housing 21. Preferably, the central layer frame 22 and the housing 21 can be bolted together for easier and faster assembly and disassembly. Further, a bulletproof module 3 is detachably installed inside the central layer frame 22. The bulletproof module 3 consists of three unit bulletproof modules 31, which can achieve multi-level and graded bulletproof protection. Further, the unit bulletproof modules 31 are fixed and arranged within the central layer frame 22 by adjusting fasteners 5, forming a layered structure. Specifically, the adjusting fasteners 5 consist of six angle iron pieces 51 and a connecting strip 513. The angle iron pieces 51 are formed by a first plate 511 and a second plate 512 perpendicular to each other. The first plate 511 is used to hold the single... The bulletproof module 31 is pressed against the interior of the central frame 22. The second plate 512 is used to fix it to the central frame 22. The two adjacent first plates 511 are connected by bolts 5121 to further clamp and fix the middle bulletproof module 31. Furthermore, the first plates 511 on the same plane are connected by connecting strips 513 to make the overall clamping and fixing effect more stable. Preferably, in order to enhance the integrity and impact resistance of the structure, a metal mesh 6 is laid and fixed between the two bulletproof modules 31. After the metal mesh 6 is installed, the bulletproof modules 31 are tightly connected by adhesive to improve the integrity. Furthermore, for sealing, a threaded and detachable back cover 211 is provided on the shell 21. Preferably, in order to prevent the bulletproof module 3 from shaking after sealing and to make it more stable, a pressing and buffering mechanism 4 is provided between the back cover 211 and the bulletproof module 3 to press and fix the bulletproof module 3 inside the shell 21. Specifically, the clamping and buffering mechanism 4 includes a clamping plate 41, which abuts against the overall rear wall of the bulletproof module 3. The clamping plate 41 is connected to the rear cover 211 by a spring 42. The spring 42 can not only provide pressure for clamping, but also play a buffering role after being impacted.

[0030] This solution employs a multi-layered bulletproof module design, where each layer absorbs and disperses the kinetic energy of the bullet, significantly improving overall bulletproof performance. The metal mesh 6 and adhesive between adjacent bulletproof modules further enhance the structural integrity and impact resistance. The detachable connection allows for the selection and replacement of modules with different bulletproof levels according to actual needs, improving the flexibility and adaptability of the security door. Furthermore, the detachability of individual modules not only avoids the high cost of replacing the entire module but also allows for adjustment of the bulletproof level as needed.

[0031] Preferably, in order to ensure the filling effect inside the shell 21, the shape and size of the central layer frame 211 are adapted to the shell 21 so that it is just filled after placement and will not shake; the shape and size of the bulletproof module 3 and the central layer frame 211 are also adapted accordingly.

[0032] Preferably, in order to make the graded bulletproof effect more obvious and to make each grade work together in bulletproofing, multiple unit bulletproof modules 31 are arranged from front to back to form a first-level bulletproof layer 311, a second-level bulletproof layer 312 and a third-level buffer layer 313; the first-level bulletproof layer 311 is made of alumina or silicon carbide; the second-level bulletproof layer 312 is made of carbon fiber reinforced plastic or glass fiber reinforced plastic; and the third-level buffer layer 313 is made of high-density foam plastic or rubber.

[0033] Example 2

[0034] The structure is the same as that of Embodiment 1, but the difference is that heat insulation, fireproofing, noise reduction and other modules can be added to the central frame 211 as needed.

[0035] How this device works:

[0036] Based on the requirement of a level 3 bulletproof door, during installation, the internal installation of the central frame 211 is completed first on the outside of the shell 21. Specifically, the first-level bulletproof layer 311 is placed inside the bottom of the central frame 211, and then the first plate 511 of the angle iron plate 51 is used to press the first-level bulletproof layer 311 against the bottom. Then, the second plate 512 of the angle iron plate 51 is fixedly connected from the side wall of the central frame 211 with bolts. After completing the installation of the first-level bulletproof layer 311, a metal mesh 6 is laid on the rear side of the first-level bulletproof layer 311 and adhesive is applied. Then, the second-level bulletproof layer 312 is placed in conjunction with the first-level bulletproof layer on the front. Layer 311 is bonded and similarly secured by angle iron pieces 51. After securing, bolts 5121 are used to pass through the bulletproof layer to connect and secure adjacent angle iron pieces 51. The same operation is performed to complete the installation of the three-level buffer layer 313. After installation, the central layer frame 211 is placed into the housing 21 and secured with bolts. After the central layer frame 211 is fully secured, the clamping plate 41 is placed against the rear side wall of the bulletproof module 3 and the rear cover 211 is placed on top and secured with bolts. After the door body 2 is installed, it is installed inside the door frame 1. This is a standard operation and will not be described in detail here. After installation, the door frame 1 is embedded into the wall and can be used.

[0037] When the bulletproof system is in use, after being impacted by a bullet, the first-level bulletproof layer 311 absorbs most of the impact force caused by the bullet's kinetic energy. The bullet's kinetic energy is absorbed step by step according to the number of levels, thereby preventing it from penetrating the door body 2 and achieving bulletproof protection.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
