Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy with mortise and tenon joints, and specifically relates to an aluminum alloy profile with mortise and tenon joints. Background Technology

[0002] Mortise and tenon joints are a core connection technique in traditional Chinese architecture and artifacts. They achieve a stable connection through the precise interlocking of protruding and recessed parts, embodying the wisdom of millennia of craftsmanship. With the development of modern materials technology, aluminum alloys, due to their high tensile strength, strong corrosion resistance, and environmental recyclability, have gradually become a superior alternative to traditional materials. Combining mortise and tenon techniques with aluminum alloy materials, resulting in mortise and tenon joint aluminum alloy profiles, is widely used in building doors and windows, ancient building restoration, and furniture manufacturing. Advances in digital processing technology have enabled high-precision replication and mass production of aluminum alloy mortise and tenon structures. This preserves the mechanical stability and cultural connotations of traditional mortise and tenon joints while fully leveraging the material advantages of aluminum alloys, meeting the diverse structural performance and durability requirements of modern applications.

[0003] Existing mortise and tenon joint aluminum alloy profiles combine the mechanical advantages of precise interlocking and stable connection in traditional mortise and tenon structures with the lightweight, high-strength, corrosion-resistant, and recyclable properties of aluminum alloy. Reliable assembly can be achieved without bolts or other additional connectors, making them suitable for various applications such as construction and furniture. Furthermore, high-precision mass production is achieved through digital processing, preserving the cultural essence of mortise and tenon joints while meeting the demands of modern production and use for structural stability, durability, and environmental friendliness.

[0004] While existing mortise and tenon joint aluminum alloy profiles combine the mechanical advantages of precise interlocking and stable connection of traditional mortise and tenon structures with the lightweight, high-strength, corrosion-resistant, and recyclable properties of aluminum alloys, they mostly rely on a single mortise and tenon interlocking structure for connection, lacking multiple auxiliary reinforcement structures. After assembly, their overall shear resistance and loosening resistance are limited. Under high-frequency vibration or long-term load-bearing conditions, they are prone to increased connection gaps and decreased stability, making it difficult to meet the needs of complex applications requiring high connection reliability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an aluminum alloy profile with mortise and tenon joints to solve the problems of aluminum alloy with mortise and tenon joints.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A tenon-and-mortise type aluminum alloy profile includes a first aluminum alloy block and a second aluminum alloy block. A first tenon groove is formed at the center of one side of the first aluminum alloy block. A first tenon block is integrally formed at one end of the second aluminum alloy block. The first tenon block slides inside the first tenon groove. Side blocks are slidably installed on both sides of the connection between the first and second aluminum alloy blocks. A plug-in plate is integrally formed at the end of the first tenon block away from the second aluminum alloy block. The plug-in plate slides inside the first aluminum alloy block. A mounting plate is slidably installed on both sides inside the first aluminum alloy block. A support plate is integrally formed at one end of the mounting plate. A protrusion is integrally formed at the end of the mounting plate away from the support plate. The protrusion slides inside the plug-in plate.

[0007] As a preferred technical solution, the plug plate has a rectangular groove inside, and multiple sliding holes are provided on both sides of the plug plate. Sliding rods are integrally formed on both sides of one end of the mounting plate near the protrusion. The protrusion slides inside the plug plate through the rectangular groove, and the sliding rods slide inside the sliding holes.

[0008] As a preferred technical solution, the first aluminum alloy block has mounting grooves on both sides inside, and the mounting plate slides through the mounting grooves on both sides inside the first aluminum alloy block.

[0009] As a preferred technical solution, the first mortise and tenon groove is provided with an insertion slot, and the insertion plate is inserted into the first aluminum alloy block through the insertion slot.

[0010] As a preferred technical solution, square grooves are provided on both sides of the first aluminum alloy block and the second aluminum alloy block, and a second mortise and tenon groove is provided at the center of the square groove. The side block is integrally formed with a second mortise and tenon block at one end close to the first aluminum alloy block and the second aluminum alloy block, and the second mortise and tenon block slides inside the second mortise and tenon groove.

[0011] As a preferred technical solution, the rectangular groove has assembly grooves on both sides and the four sides of the side block. A first assembly block is slidably installed inside the assembly groove on the inner side of the side block. The first assembly block has multiple circular grooves inside. A second assembly block is slidably installed inside the assembly groove on the outer side of the side block. A circular rod is integrally formed on one side of the second assembly block, and the circular rod slides inside the circular groove.

[0012] As a preferred technical solution, the side blocks have assembly slots on both sides, and the assembly slots have through slots inside, through which the circular rod is slidably installed.

[0013] In summary, the present invention has the following main advantages: First, in actual use, when the profile is subjected to longitudinal tension, transverse shear force or high-frequency vibration, the external force will be distributed to each connection structure rather than concentrated on a certain component. For example, the longitudinal tension will be borne by the plug plate and the protrusion, while the lateral impact force will be resisted by the side block and the second tenon structure. This effectively avoids deformation and loosening of the connection parts due to stress concentration, greatly improves the fatigue resistance and service life of the profile, and can meet the needs of long-term load-bearing or complex working conditions. Secondly, in actual use, when the profile is subjected to longitudinal tension, transverse shear force or high-frequency vibration, the external force will be distributed to each connection structure rather than concentrated on a certain component. For example, the longitudinal tension will be borne by the plug plate and the protrusion block, while the lateral impact force will be resisted by the side block and the second tenon structure. This effectively avoids deformation and loosening of the connection parts due to stress concentration, greatly improves the fatigue resistance and service life of the profile, and can meet the needs of long-term load-bearing or complex working conditions. Third, the combination of mortise and tenon joint structure and aluminum alloy material can give full play to the ductility and toughness of aluminum alloy, so that each connecting part can produce slight elastic deformation when subjected to force, absorb part of the external force, and then rely on the elasticity of the material itself to restore the original shape, avoiding structural breakage due to rigid collision. At the same time, the corrosion resistance of aluminum alloy can ensure that the profile can be used for a long time in harsh environments such as humidity, acid and alkali, without connection failure caused by component corrosion. It is suitable for special scenarios such as outdoor buildings and auxiliary components of marine platforms. Attached Figure Description

Detailed Implementation

[0016] Example

[0017] refer to Figures 1-4 This embodiment of an aluminum alloy profile with a mortise and tenon joint includes a first aluminum alloy block 1 and a second aluminum alloy block 2. A first mortise and tenon groove 5 is provided at the center of one side of the first aluminum alloy block 1. A first mortise and tenon block 9 is integrally formed at one end of the second aluminum alloy block 2. The first mortise and tenon block 9 slides inside the first mortise and tenon groove 5. Side blocks 4 are slidably installed on both sides of the connection between the first aluminum alloy block 1 and the second aluminum alloy block 2. A plug-in plate 7 is integrally formed at the end of the first mortise and tenon block 9 away from the second aluminum alloy block 2. The plug-in plate 7 slides inside the first aluminum alloy block 1. A mounting plate 13 is slidably installed on both sides inside the first aluminum alloy block 1. A support plate 3 is integrally formed at one end of the mounting plate 13. A protrusion 21 is integrally formed at the end of the mounting plate 13 away from the support plate 3. The protrusion 21 slides inside the plug-in plate 7.

[0018] refer to Figures 2 to 3 The plug-in plate 7 has a rectangular groove 8 inside, and multiple sliding holes 6 are formed on both sides of the plug-in plate 7. Sliding rods 22 are integrally formed on both sides of one end of the protrusion 21 near the mounting plate 13. The protrusion 21 slides inside the plug-in plate 7 through the rectangular groove 8, and the sliding rods 22 slide inside the sliding holes 6. A plug-in groove 23 is formed inside the first tenon groove 5, and the plug-in plate 7 is inserted into the first aluminum alloy block 1 through the plug-in groove 23. Assembly grooves 12 are formed on both sides of the rectangular groove 8 and on all four sides of the side block 4. A first assembly block 14 is slidably installed inside the inner assembly groove 12 of the side block 4. Multiple circular grooves 15 are formed inside the first assembly block 14. A second assembly block 14 is slidably installed inside the outer assembly groove 12 of the side block 4. Both the first and second assembly blocks 17 have integrally formed circular rods 16 on one side. The circular rods 16 slide inside the circular grooves 15. The dimensions of the first tenon block 9 and the first tenon groove 5 are precisely matched, which can achieve preliminary positioning and connection, providing basic support for the subsequent assembly of multiple reinforcement structures. As the first tenon block 9 slides forward, the plug plate 7 at the end away from the second aluminum alloy block 2 simultaneously enters the pre-set plug groove 23 inside the first tenon groove 5, and finally slides into the internal cavity of the first aluminum alloy block 1. The setting of the plug plate 7 is equivalent to adding a longitudinal "extension latch" on the basis of the main tenon structure, which effectively increases the contact area between the two aluminum alloy blocks and disperses the force on the connection part.

[0019] refer to Figures 2 to 4The first aluminum alloy block 1 has mounting grooves 10 on both sides inside. The mounting plate 13 slides through the mounting grooves 10 on both sides inside the first aluminum alloy block 1. The first aluminum alloy block 1 and the second aluminum alloy block 2 both have square grooves 11 on both sides. The center of the square groove 11 has a second mortise and tenon groove 20. The side block 4 has a second mortise and tenon block 19 integrally formed at one end of the first aluminum alloy block 1 and the second aluminum alloy block 2. The second mortise and tenon block 19 slides inside the second mortise and tenon groove 20. The side block 4 has assembly grooves 12 on both sides. The assembly grooves 12 have through grooves 18 inside. The round rod 16 slides through the through grooves 18. The core component, side block 4, is installed inside the circular groove 15. Square grooves 11 are opened on both sides of the first aluminum alloy block 1 and the second aluminum alloy block 2. The second mortise and tenon groove 20 at the center of the square groove 11 is precisely matched with the second mortise and tenon block 19 integrally formed at one end of the side block 4. The operator aligns the two side blocks 4 with the square grooves 11 on both sides of the connection and slides the second mortise and tenon block 19 into the second mortise and tenon groove 20 to achieve the connection between the side block 4 and the main profile. The side block 4 can cover the lateral gap of the main mortise and tenon connection to prevent external dust and moisture from entering the profile and causing the component to rust.

[0020] Operating principle and advantages: The core connection of this profile is the sliding engagement of the first mortise and tenon groove 5 and the first mortise and tenon block 9. In the initial assembly stage, the operator aligns the integrally formed first mortise and tenon block 9 at the end of the second aluminum alloy block 2 with the first mortise and tenon groove 5 located at the center of one side of the first aluminum alloy block 1, and smoothly pushes it in along a straight line. During this process, the dimensions of the first mortise and tenon block 9 and the first mortise and tenon groove 5 are precisely matched, achieving initial positioning and connection, providing basic support for the subsequent assembly of multiple reinforcement structures. As the first mortise and tenon block 9 slides forward, its insertion plate 7, located away from the second aluminum alloy block 2, simultaneously enters the pre-set insertion slot 23 inside the first mortise and tenon groove 5, and finally slides into the inner part of the first aluminum alloy block 1. The cavity and the insertion plate 7 are equivalent to adding a longitudinal "extension latch" to the main mortise and tenon structure, effectively increasing the contact area between the two aluminum alloy blocks, dispersing the stress on the connection part, and avoiding the stress concentration problem caused by the small contact area in the traditional single mortise and tenon structure. After the insertion plate 7 is completely slid into the first aluminum alloy block 1, the operator can push the mounting plate 13, which is slidably installed in the mounting grooves 10 on both sides of the first aluminum alloy block 1, through the reserved operating port of the first aluminum alloy block 1. One end of the mounting plate 13 has a support plate 3 integrally formed, and the other end has a protrusion 21. During the pushing process, the mounting plate 13 moves in a straight line along the mounting groove 10, causing the protrusion 21 to slide into the insertion plate 7. In the rectangular groove 8, the lateral positioning of the insertion plate 7 is completed. At the same time, the sliding rods 22 on both sides of the mounting plate 13 near the protrusion 21 will be inserted into the multiple sliding holes 6 on both sides of the insertion plate 7. The cooperation between the sliding rods 22 and the sliding holes 6 further restricts the displacement of the mounting plate 13 itself, ensuring that the protrusion 21 can be stably engaged in the rectangular groove 8, preventing the insertion plate 7 from loosening or falling out when subjected to longitudinal tension or vibration. At this time, the mounting plate 13, the insertion plate 7 and the first aluminum alloy block 1 form a built-in triangular stabilizing structure, transforming the "surface contact" of the main tenon connection into "multi-point contact", greatly improving the shear resistance of the connection. After the limiting structure is assembled, the connection between the first aluminum alloy block 1 and the second aluminum alloy block 2 needs to be reinforced laterally. The core component is the side block 4. Square grooves 11 are opened on both sides of the first aluminum alloy block 1 and the second aluminum alloy block 2. The second tenon groove 20 at the center of the square groove 11 is precisely matched with the second tenon block 19 integrally formed at one end of the side block 4. The operator aligns the two side blocks 4 with the square grooves 11 on both sides of the connection and slides the second tenon block 19 into the second tenon groove 20 to achieve the connection between the side block 4 and the main profile. The side block 4 can cover the lateral gap of the main tenon connection to prevent external dust and moisture from entering the profile and causing the component to rust.On the other hand, the relative displacement of the first aluminum alloy block 1 and the second aluminum alloy block 2 can be restricted from both sides, preventing misalignment of the two components when subjected to lateral impact force, and further enhancing the stability of the overall structure. To achieve ultimate stability of the connection structure, this profile has assembly slots 12 on both sides inside the rectangular groove 8 and on all four sides of the side block 4, and a secondary locking structure for the first assembly block 14 and the second assembly block 17 is designed accordingly. After the side block 4 is installed in place, the operator first slides the first assembly block 14 into the assembly slot 12 inside the side block 4, and then installs the second assembly block 17 into the assembly slot 12 outside the side block 4. At this time, the integrally formed circular rod 16 on one side of the second assembly block 17 will pass through the through opening in the assembly slot 12 of the side block 4. The groove 18 is precisely inserted into the circular groove 15 inside the first assembly block 14. The tight fit between the circular rod 16 and the circular groove 15 firmly connects the first assembly block 14 and the second assembly block 17 into a whole. This, in turn, links and locks the side block 4 with the insertion plate 7 and the mounting plate 13. This structure is equivalent to establishing a "force transmission bridge" between the inside and outside of the profile, making the various components form a mutually restrictive and mutually supportive linkage system. This completely eliminates the impact of a single loose component on the overall connection. After all the structures are assembled, the connection system of this profile is completed. The entire process does not require the use of bolts, rivets, or other additional connectors. It relies entirely on the nesting and interlocking of its own structure to achieve a stable connection. Assembly and disassembly are convenient, and the profile is reusable.
