Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profiles, in particular to an anti-extrusion aluminum alloy profile. Background Art

[0002] Aluminum alloy profiles are a type of material made by processing aluminum and other alloying elements into a specific cross-sectional shape. They are widely used in fields such as construction, transportation, and electronic equipment. Aluminum alloy profiles are characterized by high strength, light weight, corrosion resistance, excellent conductivity, and good processability. However, in actual use, certain scenarios will produce strong extrusion stress on the profile. If the profile's extrusion resistance is insufficient, it may cause deformation, fracture, and even structural failure. Therefore, the research and development of aluminum alloy profiles with high extrusion resistance is of great significance for improving product performance, extending service life, and ensuring safety.

[0003] At present, aluminum alloy profiles on the market are usually produced through an extrusion process and have a fixed cross-sectional shape and structure. Their strength mainly depends on the composition of the material, the heat treatment process, and the rationality of the cross-sectional design. In actual engineering applications, in order to meet greater load-bearing needs or complex structural requirements, it is often necessary to splice multiple aluminum alloy profiles. However, the common splicing methods currently include bolt connections, welding, and snap-on devices. Although these traditional methods have a certain connection strength, they often suffer from insufficient overall compressive resistance due to problems such as stress concentration or structural looseness at the splicing points, limiting their application in high-load environments. Therefore, an anti-extrusion aluminum alloy profile is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides an anti-extrusion aluminum alloy profile, which aims to improve the problems of stress concentration or structural looseness at the splicing points in the prior art, resulting in insufficient overall compressive performance.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An anti-extrusion aluminum alloy profile comprises a profile body, an extension frame fixedly connected to one side of the profile body, a bolt hole extending through the extension frame, a fixing bolt provided on a side of the profile body away from the extension frame, the fixing bolt being threadedly connected to the bolt hole, a positioning assembly provided on a side wall of the extension frame, a reinforcement assembly provided inside the profile body, and a sealing ring fixedly connected to a side of the profile body close to the extension frame;

[0021] A clamping edge is provided inside the profile body on one side away from the extension frame, and the extension frame is fitted with the clamping edge.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the present invention, the embedded design of the extension frame and the slide groove optimizes the force distribution, reduces stress concentration, and improves the compressive resistance.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: an anti-extrusion aluminum alloy profile, including a profile body 1, an extension frame 2 is fixedly connected to one side of the profile body 1, a bolt hole 5 is opened inside the extension frame 2, a fixing bolt 9 is provided on the side of the profile body 1 away from the extension frame 2, the fixing bolt 9 is threadedly connected to the inside of the bolt hole 5, a positioning component is provided on the side wall of the extension frame 2, a reinforcement component is provided inside the profile body 1, a sealing ring 13 is fixedly connected to the side of the profile body 1 close to the extension frame 2, and the sealing ring 13 ensures the tightness of the connection after the two profile bodies 1 are spliced; the positioning component includes The corner block 3 is bracketed, and the side walls of the corner block 3 are fixedly connected to the side walls of the extension frame 2. The outer side walls of the extension frame 2 are fixedly connected with rubber blocks 4. Bolt holes 5 are opened between the rubber blocks 4. A limiting groove 6 is opened inside the side of the profile body 1 away from the extension frame 2. A slide groove 7 is opened on the side of the profile body 1 away from the extension frame 2. The slide groove 7 coincides with the corner block 3. The corner block 3 is slidably connected inside the slide groove 7. The limiting groove 6 coincides with the rubber block 4. The rubber block 4 is slidably connected inside the limiting groove 6. A card edge 8 is opened inside the side of the profile body 1 away from the extension frame 2, and the extension frame 2 fits with the card edge 8.

[0032] When splicing multiple profile bodies 1, the extension frame 2 connected to one profile body 1 is inserted into the interior of the profile body 1 on the other side to form a tightly fitting structure. During this process, the corner block 3 slides into the interior of the slide groove 7, providing a linearly guided splicing method, effectively reducing the splicing deviation and improving the overall compressive resistance of the structure. At the same time, the rubber block 4 undergoes elastic deformation due to force extrusion, forming a stable buffering effect, which not only reduces the direct impact force between components, but also enhances the fatigue resistance, thereby improving the stability of the splicing point under long-term pressure. When the edge of the extension frame 2 fits with the card edge 8, the rubber block 4 just moves to the top of the limit groove 6. At this time, the rubber block 4 is no longer squeezed and relies on its own elasticity to complete the reset and snap into the interior of the limit groove 6. The above method not only achieves the convenience of splicing operation, but also ensures the stability of the initial connection, providing support for bearing higher compressive stress. Subsequently, the bolt holes 5 opened in the extension frame 2 are automatically aligned with the holes reserved in the profile body 1. This alignment avoids the stress concentration phenomenon caused by connection errors. Next, by screwing the fixing bolts 9 into the bolt holes 5, the two profile bodies 1 are further reinforced and connected to form a multi-fixed splicing structure. This double-layer protection design improves the reliability and compressive resistance of the overall splicing, ensuring that the structure will not loosen or shift under high load conditions. The splicing effectively disperses the compressive stress through the combination of elastic buffering and multi-point fixation, thereby improving the overall strength and compressive resistance of the splicing structure.

[0033] Reference Figure 1-Figure 3The reinforcement component includes reinforcement ribs 10. The side walls of the reinforcement ribs 10 are fixedly connected to the inside of the profile body 1, which enhances the overall stability and compressive resistance of the profile. The reinforcement ribs 10 are arranged in a linear array, that is, a plurality of the reinforcement ribs 10 are evenly arranged along the straight line, which optimizes the force distribution and makes the structure more uniform and reliable. An inner groove 11 is opened inside the profile body 1, and a reinforcement strip 12 is arranged inside the profile body 1. The reinforcement strips 12 are arranged in a linear array inside the inner groove 11, which effectively improves the durability and deformation resistance of the profile under multi-directional forces.

[0034] Working principle: When splicing multiple profile bodies 1, insert the extension frame 2 connected to one profile body 1 into the profile body 1 on the other side, so that the corner block 3 slides into the inside of the slide groove 7. At this time, the rubber block 4 will be squeezed and deformed. When the extension frame 2 is in contact with the card edge 8, the rubber block 4 just moves to the top of the limit groove 6. At this time, the rubber block 4 loses the extrusion force and is reset, and is stuck in the inside of the limit groove 6. The preliminary splicing of the two profile bodies 1 is completed. At this time, the bolt hole 5 opened in the extension frame 2 is just aligned with the reserved hole in the profile body 1, and then the fixing bolt 9 is screwed into the inside of the bolt hole 5 to further fix the two profile bodies 1 to ensure the firmness of the connection.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
