MULTI-ADAPTIVE TACTICAL SUPPORT SHAPING STORAGE PLUG-IN

Description

TECHNICAL FIELD

This invention belongs to the technical field of tactical equipment accessories, specifically involving a multi-adaptation tactical bracket shaping storage insert.

BACKGROUND TECHNOLOGY

The tactical mount is the core auxiliary component of tactical firearms equipment. Among them, the SBA3 and its derivative models are widely used due to their structural stability and operational flexibility.

However, such tactical scaffolds commonly present the following issues during storage, transportation, and handling:

• • 1. The current SBA3 and its derivative tactical support models have some plug-in components with weak material and insufficient compression resistance, which are prone to deformation due to compression or impact. During installation, these components may interfere with internal structures such as belts and buckles, leading to installation difficulties or even wear on the support body, thereby affecting its structural accuracy and operational safety.
  • 2. Tactical equipment requires complementary small accessories such as spare screws, washers, tactical pins, and micro tools. However, current SBA3 and its derivative models only provide shaping support without storage features or dedicated compartments, making them prone to loss and confusion. This inconvenience hinders user operations. Moreover, some storage accessories lack shaping protection, and small accessories are susceptible to deformation during transportation due to shaking or collisions, failing to meet users' integrated needs.
  • 3. Most plug-in accessories for current SBA3 and its derivative models are designed for single models—either the SBA3 base or specific variants-lacking universal compatibility. Users must purchase separate components for each model, resulting in high costs and limited versatility.
  • 4. Current SBA3 and its derivative tactical stents predominantly employ fixed manufacturing processes, which struggle to balance mass production efficiency with personalized and small-batch customization needs. Additionally, some products exhibit insufficient dimensional accuracy, resulting in poor compatibility with SBA3 and its derivative stents.

Therefore, a multi-adaptation tactical bracket molding storage plug is designed to solve the above technical problems.

INVENTION CONTENT

To address the issues outlined in the prior art, this invention provides a multi-adaptive tactical bracket shaping storage insert, featuring high strength, easy installation, and broad compatibility.

To achieve the aforementioned objectives, the present invention provides the following technical solution: A multi-adaptive tactical bracket shaping storage insert, comprising an elastic first insert and a second insert, both formed by injection molding of engineering plastics or 3D printing of engineering-grade materials, designed for full-fit SBA3 and its derivative tactical bracket models. The inserts feature symmetrical grooves on both sides corresponding to the belt and buckle mounting positions within the SBA3 and its variants. Each insert contains a micro-constricted storage cavity, with the first insert being elastically snap-fitted into the corresponding cavity.

Furthermore, the specific steps for forming the first and second plugs through injection molding of engineering plastics include:

Engineering plastics are formed through injection molding using PC/ABS alloy plastic, with the injection mold being designed and manufactured based on the optimized 3D model of SBA3 and its derivative tactical bracket models.

Furthermore, the specific steps for forming the first and second plugs using engineering-grade 3D printing materials are as follows:

The engineering-grade 3D printing consumables are fabricated using SBA3 and its derivative tactical bracket models optimized for 3D printers, with carbon fiber-reinforced PETG as the core material.

Furthermore, the process for obtaining 3D models of the optimized SBA3 and its derivative tactical support models includes:

The process begins with precise 3D modeling of the core dimensions of the SBA3 and its derivative tactical support systems, extracting shared spatial parameters. The end and side structures are then optimized with an elastic allowance of ≤0.3 mm. Finally, finite element analysis is performed on critical support points to refine their distribution, resulting in the final 3D model of the optimized SBA3 and its variants.

Furthermore, the edges of both the first and second plugins are rounded.

Furthermore, the surfaces of both the first and second plugs undergo polishing and grinding.

Furthermore, the inner wall of the storage cavity is treated with a micro-sanding finish.

Compared with existing technologies, the present invention offers the following advantages:

• • 1. This invention is manufactured through injection molding of a three-dimensional model of an optimized tactical bracket made from PC/ABS alloy plastic, or via 3D printing of carbon fiber-reinforced PETG using the same optimized model. Both materials exhibit exceptional impact resistance, rigidity, and weather resistance. The precision-engineered inserts, guided by the optimized bracket model, ensure full-contact alignment with the tactical bracket, delivering uniform and targeted support. This design effectively resists external compression, overcoming the material weaknesses and brittleness of conventional counterparts. The product is engineered for diverse applications including outdoor environments, storage facilities, and extreme temperature conditions.
  • 2. This invention incorporates recesses on both sides of the belt and buckle mounting positions within the tactical bracket, enabling precise avoidance of internal components to prevent interference. The rounded transitions and smooth surface treatment ensure smooth installation while completely eliminating bracket wear, effectively addressing the core pain points of existing tactical bracket installation interference and structural damage.
  • 3. The invention features a storage compartment with an elastic micro-constricted opening, enabling secure storage of small accessories. Compared to existing products, it demonstrates significantly enhanced targeted shaping protection and practical storage capabilities, meeting users' integrated usage requirements.
  • 4. The optimized tactical bracket's 3D model in this invention is developed through a precision 3D modeling process. First, the core dimensions of the SBA3 and its derivative models serve as the baseline for extracting shared internal spatial parameters. The end and side structures are then optimized with an elastic compatibility allowance of ≤0.3 mm. Subsequently, finite element analysis is performed on critical support points to refine their distribution. This approach ensures full compatibility with both the SBA3 and its variants, covering mainstream base models and niche derivative specifications. By eliminating the need for separate accessories for different bracket types, the solution significantly reduces user costs while enhancing product versatility and market reach.
  • 5. This invention integrates injection molding and 3D printing processes. The injection molding process supports mass production, while the 3D printing process enables rapid customization and special model adaptation.
  • 6. The invention comprises an elastic snap-fit first plug and a second plug, designed to support backup, replacement, or multi-stand usage, suitable for tactical training, outdoor hunting, equipment storage, and military/police operations.

SPECIFIC IMPLEMENTATION METHOD

The following section will provide a clear and comprehensive description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. It should be noted that the described embodiments represent only a subset of the invention's possible implementations, not its entirety. Furthermore, all additional embodiments conceived by those skilled in the art without inventive effort, based on the disclosed embodiments, shall be deemed within the scope of protection of the present invention.

Example 1

(1) Material Selection for Injection Molding Process

The selected PC/ABS alloy engineering plastic must meet the following performance requirements: impact strength ≥20 KJ/m², stiffness modulus ≥2500 MPa, heat deformation temperature ≥110° C., and weather resistance compliant with GB/T 14522-2008 standards. It must also pass the material compatibility test for tactical equipment components.

(2) Structure Processing and Manufacturing Technology

1. Enhanced 3D Modeling and Optimization

The internal contour dimensions of SBA3 and three or more derivative models in the same series were collected by precision 3D scanning technology, and a 3D dimensional database was established to extract common structural features and dimensional variation ranges.

The plug-in benchmark model is designed based on the dimensional database, with optimized side and end fitting structures, and an elastic compatibility allowance of ≤0.3 mm to ensure the model covers target fitting models.

The storage layer is designed with specified dimensions and a micro-elastic closure structure, featuring a micro-sandblasted texture on its inner surface.

The finite element analysis is carried out on the key support position of the plug-in, and the distribution of the support structure is optimized to ensure that there is no deformation under the pressure of 50N;

2. Mold Preparation

The injection mold is designed by 3D model, and it is made of P20 mold steel. It is processed by high precision CNC, and the surface roughness of mold cavity is Ra≤0.08 μm, which ensures the smooth surface of the insert after molding.

The mold should include the main body of the plug, the double groove structure, the storage layer and the forming cavity of the micro-elastic retraction structure, and set the reasonable gate and cooling system to ensure the forming efficiency and product consistency;

3. Forming and Post-Processing

The PC/ABS alloy plastic was put into the injection molding machine, and the process parameters were set as follows: barrel temperature 230-250° C., mold temperature 80-90° C., injection pressure 15-20 MPa, holding time 5-8 seconds, cooling time 10-15 seconds.

After mold release and blank extraction, the components undergo ultrasonic deburring (3-5 minutes), surface and storage layer polishing (using 800-mesh sandpaper), and micro-elastic closure structure shaping. This ensures smooth edges with no sharp edges and meets the required elasticity standards for the closure structure. The final products are the elastic first insert 101 and second insert 104, featuring dual grooves 102 and storage cavity 103. The first insert 101 is assembled into the multi-adapter tactical support plastic storage insert by elastic snap-fit into the storage cavity 103 of groove 102.

4. Installation and Usage

Identify the plug installation orientation based on the tactical bracket model (SBA3 and its derivative variants), where the dual grooves 102 correspond to the belt and buckle positions within the SBA3 and related models.

Align the multi-adaptation tactical bracket shaping storage plug with the internal mounting port of the SBA3 and its derivative models, then smoothly slide it along the contour of the SBA3 and its derivative models until the shaping storage plug fully adheres to the inner wall of the SBA3 and its derivative models, completing the shaping fixation.

Insert the accessory into storage compartment 103, where the elastic micro-closure ensures secure and stable placement without wobbling.

To remove or disassemble the multi-adaptation tactical support shaping storage plug, simply reverse-slide the plug to extract it. This operation is convenient and does not damage the SBA3 or other derivative models of the tactical support series.

When replacing the plug-in, detach the first plug-in 101 and the second plug-in 104, then replace either the first plug-in 101 or the second plug-in 104.

When replacing the tactical bracket (SBA3 and its derivative models) for different variants, there's no need to replace the multi-adaptation tactical bracket's shaping storage plug-in. Just follow the above steps for installation, and the compatibility remains unchanged without additional adjustments.

For tactical airframes (SBA3 and its variants) of different models, the first plug-in 101 and second plug-in 104 can be separated and installed directly following the aforementioned procedure.

Example 2

(1) Material Selection and Preparation for 3D Printing Processes

The carbon fiber-reinforced PETG material must meet the following performance criteria: tensile strength ≥55 MPa, flexural strength ≥75 MPa, and elongation at break ≥3%. The printed product must be free from interlayer cracking to ensure structural integrity and molding support capacity, thereby preventing deformation or failure caused by material issues.

The finite element analysis is carried out on the key support position of the plug-in, and the distribution of the support structure is optimized to ensure that there is no deformation under the pressure of 50N;

2. Mold and Printing File Preparation

Export 3D models as STL files and organize them into a model library by categorizing them according to different compatible models.

During slicing, set the parameters as follows: layer height 0.1 mm, fill density 85%, and support type as biodegradable water-soluble support to ensure structural integrity, dimensional accuracy, and surface quality of the printed product.

3. Forming and Post-Processing

Load the 3D-printed file into an industrial-grade FDM 3D printer, insert the selected carbon fiber-reinforced PETG filament, and perform layer-by-layer printing according to preset parameters.

After printing, remove the support structure and clean surface residues with 95% alcohol for 2-3 minutes. Then lightly sand the edges and storage layer using 1000-mesh sandpaper to ensure surface roughness (Ra≤0.8 μm) and eliminate interlayer protrusions. This yields the elastic first insert (101) and second insert (104) with dual grooves (102) and storage cavity (103). The first insert (101) is assembled into the multi-adapter tactical support plastic storage insert by elastic snap-fit into the storage cavity (103) of groove (102).
