Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, specifically relating to an aluminum profile that is easy to assemble and splice. Background Technology

[0002] Aluminum possesses excellent properties such as being lightweight, corrosion-resistant, thermally and electrically conductive, and malleable. Compared to other metal materials, it has a lower density and lighter weight, making it easier to process and transport. Furthermore, aluminum exhibits good corrosion resistance, resisting oxidation, corrosion, and the erosion of acids and alkalis for extended periods. In addition, aluminum has high thermal and electrical conductivity, making it suitable for applications such as heat dissipation and electrical wiring. Aluminum also has good malleability, allowing it to be processed into various shapes through rolling, stretching, and other techniques, resulting in its wide application across various fields.

[0003] When existing conventional aluminum profiles are assembled and spliced, such as Figure 1 As shown, the first aluminum profile 1 and the second aluminum profile 2 are generally connected by a connecting sleeve 3, and further fixed by screws 4 to complete the assembly of the aluminum profiles. During assembly, because the outer diameter of the connecting sleeve 3 at the connection point is larger than the outer diameter of the aluminum profiles on both sides, the height and thickness of the connection point are greater than those of the aluminum profiles on both sides. This results in an uneven surface of the aluminum profile in this section. The protruding screws on it further exacerbate this problem, affecting the flatness of the aluminum profile. During construction, it is necessary to use a shim to raise and support the gaps, or to fill the gaps with foam glue, but the results are not satisfactory.

[0004] Therefore, this utility model proposes a new type of aluminum profile that is easy to assemble and splice. Two aluminum profiles are connected by a connecting tube, and then further limited and fixed by a limit pin that can elastically extend and retract on the connecting tube, so as to complete the assembly and splicing of the aluminum profiles. It is simple, convenient, labor-saving and easy to use, and the connection is stable. At the same time, there is no external protrusion at the connection, so that the aluminum profiles can be used flat, which is better. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 2-8 This utility model provides the following technical solution: an aluminum profile that is easy to assemble and splice, including a first aluminum profile 1, a second aluminum profile 2, and a connecting tube 6. The connecting tube 6 is disposed between the first aluminum profile 1 and the second aluminum profile 2, and its left and right ends are respectively inserted and connected to the first aluminum profile 1 and the second aluminum profile 2. A positioning outer frame strip 7 is fixedly connected to the outer perimeter of the middle position of the connecting tube 6. The outer diameter of the positioning outer frame strip 7 is the same as the outer diameter of the first aluminum profile 1 and the second aluminum profile 2. Both the left and right ends of the connecting tube 6 are integrally formed with arc-shaped tube heads 8. An inner support frame 15 is fixedly connected to the middle position of the inside of the connecting tube 6. The structure is "X" shaped. The outer diameter of the connecting tube 6 is adapted to the inner diameter of the first aluminum profile 1 and the second aluminum profile 2. The connecting tube 6 can be inserted into the first aluminum profile 1 and the second aluminum profile 2. The positioning frame 7 is used to center the first aluminum profile 1 and the second aluminum profile 2 when they are inserted. The height and width of the positioning frame 7 are the same as the height and width of the first aluminum profile 1 and the second aluminum profile 2, so that there is no external protrusion at the connection of the two aluminum profiles and the connection is relatively flat. The arc-shaped tube head 8 is used to facilitate the smooth insertion of the two ends of the connecting tube 6 into the aluminum profile. The internal support frame 15 can improve the internal structural strength of the connecting tube 6, thereby improving the structural strength of the connection of the two aluminum profiles.

[0026] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, furthermore, fixed sleeves 9 are fixedly connected to the middle positions of the left and right ends of the connecting tube 6. A spring 10 is provided at the bottom of the inner end of the fixed sleeve 9, and the bottom end of the spring 10 is fixedly connected to the inner wall of the bottom end of the fixed sleeve 9. A limiting pin 11 is movably connected to the upper end of the inner end of the fixed sleeve 9. The upper end surface of the limiting pin 11 is inclined, and the upper end of the spring 10 is fixedly connected to the bottom end of the limiting pin 11. A limiting sliding shaft 13 is fixedly connected to the middle positions of the front and rear sides of the bottom end of the limiting pin 11. A limiting sliding groove 14 is opened at the bottom ends of the front and rear sides of the fixed sleeve 9, and the limiting sliding shaft 13 is slidably connected to the limiting sliding groove 14. An opening 12 is opened at the middle position of the upper part of both ends of the connecting tube 6, and the upper end of the limiting pin 11 is movably connected to the opening 12. A limiting hole 5 is opened at the middle position of the upper part of both ends of the first aluminum profile 1 and the second aluminum profile 2, and the limiting pin 11 is movably connected to the opening 12. The upper end of the limiting pin 11 engages with the limiting hole 5. During the insertion of the aluminum profile and the connecting tube 6, when the upper end of the inclined surface of the limiting pin 11 touches the insertion end of the aluminum profile, it is subjected to the squeezing force. The upper end of the limiting pin 11 can temporarily retract downward into the opening 12 and further compress the spring 10 downward. At the same time, the limiting slide 13 slides relative to the limiting slide groove 14 to guide and limit the pin, preventing the limiting pin 11 from moving left and right. When the aluminum profile is inserted into place, the opening 12 aligns with the limiting hole 5, and the squeezing force on the upper part of the limiting pin 11 disappears. Under the rebound force of the spring 10, the limiting pin 11 can rebound upward on its own, and its upper end can lock into the limiting hole 5 to achieve the limiting connection between the connecting tube 6 and the aluminum profile. This is simple, convenient, labor-saving, and stable. At the same time, the subsequent segmentation and disassembly of the aluminum profile is also convenient and quick, making it a superior choice.

[0027] In this embodiment, the present invention includes a first aluminum profile 1, a second aluminum profile 2, and a connecting tube 6. Limiting holes 5 are provided at the upper parts of both ends of the first aluminum profile 1 and the second aluminum profile 2. The first aluminum profile 1 and the second aluminum profile 2 are connected by the connecting tube 6. The positioning outer frame strip 7 at the middle position of the connecting tube 6 is used for centering during the connection. Then, the limiting pins 11 located in the fixing sleeves 9 at both ends of the connecting tube 6 automatically spring up and lock into the limiting holes 5, further limiting and fixing the connected first aluminum profile 1 and the second aluminum profile 2, thereby completing the combination and splicing of the first aluminum profile 1 and the second aluminum profile 2. Similarly, the combination and splicing of multiple aluminum profiles can be completed. It is simple, convenient, labor-saving, and the connection is stable. At the same time, there is no external protrusion at the connection, so that the aluminum profiles can be used flat, which is better than other methods.

[0028] The usage process and working principle of this utility model are as follows: When the first aluminum profile 1 and the second aluminum profile 2 are assembled, the left end of the connecting tube 6 is first inserted into the right end of the first aluminum profile 1, and centered by the positioning outer frame strip 7 in the middle of the connecting tube 6. During this process, when the upper end of the inclined surface of the limiting pin 11 in the fixing sleeve 9 at the left end of the connecting tube 6 touches the upper part of the right end of the first aluminum profile 1, it is subjected to the squeezing force. The upper end of the limiting pin 11 can temporarily retract downward into the opening 12 and further compress the spring 10 downward. At the same time, the limiting slide 13 slides relative to the limiting slide groove 14 to guide and limit the movement of the limiting pin 11, preventing it from swinging left and right. When the left end of the connecting tube 6 is inserted into the right end of the first aluminum profile 1, the opening 12 on the left end of the connecting tube 6 is aligned with the limiting hole 5 on the right end of the first aluminum profile 1, the squeezing force on the upper part of the limiting pin 11 disappears, and the spring 10 returns to its original position. Under the elastic force, the limiting pin 11 springs back and moves upward on its own. Its upper end extends out of the opening 12 and is further locked in the limiting hole 5 to realize the limiting connection between the left end of the connecting tube 6 and the first aluminum profile 1. Then, the right end of the connecting tube 6 is inserted into the left end of the second aluminum profile 2. Similarly, the connection between the right end of the connecting tube 6 and the second aluminum profile 2 is completed, thus completing the combination splicing of the first aluminum profile 1 and the second aluminum profile 2. Similarly, the combination splicing of multiple aluminum profiles can be completed. It is simple, convenient, labor-saving, and the connection is stable. At the same time, there is no external protrusion at the connection point, so that the aluminum profile can be used flat, which is better. In the future, by pressing the limiting pin 11 downward from the limiting hole 5 and the opening 12, the upper end of the limiting pin 11 can be dislodged from the limiting hole 5, thereby releasing the limiting connection between the aluminum profile and the connecting tube 6. Then, the aluminum profile can be further pulled away from the connecting tube 6 to perform the segmentation and disassembly operation of the aluminum profile.
