Description

Technical Field

[0001] This utility model relates to the field of aluminum profile connection technology, and in particular to a high-strength connection angle bracket. Background Technology

[0002] Aluminum profile frames are widely used in industrial automation equipment, workbenches, and guardrails due to their advantages such as lightweight, flexibility, and corrosion resistance. In frame assembly, corner brackets are one of the most critical components for achieving vertical connections between profiles.

[0003] However, existing standard corner brackets have several shortcomings: First, many corner brackets sacrifice compatibility with specific profile types for the sake of versatility. For example, using a 4545 corner bracket to connect a 6060 profile results in insufficient coverage area and inadequate contact surface, leading to insufficient connection rigidity. Second, under heavy loads or vibration and impact conditions, traditional corner brackets have limited structural strength, making them prone to elastic deformation or even permanent damage, affecting the accuracy and stability of the entire frame. Third, heavy-duty connection solutions on the market typically rely on complex custom parts or connection plates requiring secondary processing, which not only significantly increases manufacturing costs but also reduces on-site assembly efficiency. To address these issues, we have introduced a high-strength connection corner bracket. Utility Model Content

[0004] This utility model discloses a high-strength connecting corner bracket, which improves upon the existing structure and its shortcomings to provide a high-strength connecting corner bracket with better practical value.

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

[0006] A high-strength connecting corner bracket includes an L-shaped corner bracket body, characterized in that two sets of locking point bases are fixedly connected to one side and the bottom of the L-shaped corner bracket body, the dimensions of the two sets of locking point bases are matched with the groove width of the standard aluminum profile, and are used to embed into the groove for positioning during installation; the two sides of the locking point base are symmetrically fixedly connected with reinforcing ribs as the main load-bearing structure.

[0007] Triangular tie rods are fixedly connected at equal intervals on both sides of the reinforcing rib, together forming a multi-level reinforced load-bearing structure;

[0008] The L-shaped corner bracket body has a circular positioning hole and a waist-shaped adjustment hole on one side and the bottom, respectively.

[0009] In a preferred embodiment, the diameter and structural design of the circular positioning hole and the waist-shaped adjustment hole are compatible with both mainstream fastener systems: "T-bolt with flange nut" and "cylindrical head socket head cap screw with T-nut".

[0010] In a preferred embodiment, the L-shaped corner bracket body is integrally formed from ACD aluminum alloy material through a die-casting process, and the surface is sandblasted.

[0011] In a preferred embodiment, the L-shaped corner bracket body is designed as an isosceles right triangle, with one side being identical to and symmetrical to the bottom structure.

[0012] The high-strength connecting angle bracket provided by this utility model has the following advantages:

[0013] Firstly, its superior load-bearing performance: By setting a composite reinforcement structure of "main reinforcing ribs + triangular tie ribs" at key stress points, the bending and torque resistance of the corner brackets is significantly improved, making the load-bearing capacity of the connection nodes far exceed that of traditional corner brackets, making it suitable for heavy-duty application scenarios.

[0014] Secondly, precise positioning and efficient assembly: The "locking base" design at the bottom achieves "embedded" pre-positioning, completely solving the problems of easy rotation and difficult alignment of the corner brackets during installation. Combined with the "waist-shaped adjustment holes" on the facade, the installation process combines high precision and high efficiency.

[0015] Thirdly, extremely high connection stability: The tight fit between the locking base and the profile groove, coupled with the large contact area and robust fastener system, forms a solid dual guarantee of "surface locking" and "groove locking", ensuring that the frame is not prone to loosening or deformation during long-term operation.

[0016] Fourth, standardization and low cost: As a standardized accessory, this corner bracket can be mass-produced through aluminum extrusion, which has a huge cost advantage and market competitiveness compared to customized connecting plates that require multiple processing steps.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] In what scenarios is the high-strength connecting corner bracket disclosed in this utility model mainly applied?

[0025] Reference Figures 1 to 5 A high-strength connecting corner bracket includes: an L-shaped corner bracket body 1, characterized in that two sets of locking bases 2 are fixedly connected to one side and the bottom of the L-shaped corner bracket body 1, the size of the two sets of locking bases 2 matches the groove width of the standard aluminum profile, and is used to embed into the groove for positioning during installation; and the two sides of the locking base 2 are symmetrically fixedly connected with reinforcing ribs 3 as the main load-bearing structure.

[0026] Triangular tie rods 6 are fixedly connected at equal intervals on both sides of the reinforcing rib 3, together forming a multi-level reinforced load-bearing structure;

[0027] The L-shaped corner bracket body 1 has a circular positioning hole 4 and a waist-shaped adjustment hole 5 on one side and the bottom, respectively.

[0028] The hole diameter and structural design of the circular positioning hole 4 and the waist-shaped adjustment hole 5 can simultaneously accommodate two mainstream fastener systems: "T-bolt with flange nut" and "cylindrical head socket head cap screw with T-nut".

[0029] The L-shaped corner bracket body 1 is integrally formed from ACD aluminum alloy material through die casting process, and the surface is sandblasted.

[0030] The above technical solution addresses several shortcomings of existing standard corner brackets: First, many corner brackets sacrifice compatibility with specific profile types for the sake of versatility. For example, using a 4545 corner bracket to connect a 6060 profile results in insufficient coverage and inadequate contact, leading to insufficient connection rigidity. Second, under heavy loads or vibration impacts, traditional corner brackets have limited structural strength, making them prone to elastic deformation or even permanent damage, affecting the accuracy and stability of the entire frame. Third, commercially available heavy-duty connection solutions typically rely on complex custom parts or connection plates requiring secondary processing, significantly increasing manufacturing costs and reducing on-site assembly efficiency. To address these issues, the following specific operation is implemented: In this high-strength connection corner bracket, the shape and size of its locking base 2 match the standard groove (e.g., a 10mm wide T-slot) of the 6060 aluminum profile, allowing it to be embedded in the profile groove during installation for initial precise positioning and to prevent rotation. On both sides of the mounting hole, a pair of symmetrically arranged reinforcing ribs 3 are the main reinforcing ribs, which are the load-bearing structure of the corner bracket core. To further disperse stress and improve torque resistance, at least two triangular tie rods 6 are integrally formed on the outside of each main reinforcing rib. These tie rods, together with the main reinforcing ribs, form a composite reinforced load-bearing structure. The circular positioning holes 4 are used for initial fastening, while the waist-shaped adjustment holes 5 facilitate fine-tuning of the position during installation, greatly improving assembly efficiency and fault tolerance. The corner bracket body is integrally formed from ACD aluminum alloy material through a die-casting process and sandblasted on the surface to enhance its mechanical properties and corrosion resistance.

[0031] Reference Figures 1 to 5 In a preferred embodiment, the L-shaped corner bracket body 1 is designed as an isosceles right triangle, with one side identical and symmetrical to the bottom structure. This symmetrical isosceles right triangle design ensures uniform force distribution on the corner bracket in all directions. This uniform force distribution effectively reduces structural damage caused by excessive localized stress, thereby improving the safety and reliability of the connection. Simultaneously, it is more aesthetically pleasing; this design makes the overall structure of the corner bracket more harmonious after installation, suitable for applications where aesthetics are paramount.

[0032] Working Principle: In use, the shape and size of the locking base 2 in this high-strength connecting angle bracket match the standard groove of the 6060 aluminum profile (e.g., a 10mm wide T-slot), allowing it to be embedded into the profile groove during installation for initial precise positioning and to prevent rotation. On both sides of the mounting hole, a pair of symmetrically arranged reinforcing ribs 3 are the main reinforcing ribs, forming the core load-bearing structure of the angle bracket. To further disperse stress and improve torque resistance, at least two triangular tie rods 6 are integrally formed on the outer side of each main reinforcing rib, forming a composite reinforced load-bearing structure together with the main reinforcing ribs. The circular positioning hole 4 is used for initial tightening, while the waist-shaped adjustment hole 5 facilitates fine-tuning of the position during installation, greatly improving assembly efficiency and fault tolerance. The angle bracket body is integrally formed from ACD aluminum alloy material through die-casting and sandblasted to enhance its mechanical properties and corrosion resistance. Content not described in detail in this specification is considered prior art known to those skilled in the art.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
