Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to an aluminum profile splicing structure with angle positioning pins. Background Technology

[0002] Aluminum profiles are metal profiles with specific cross-sections made primarily of aluminum through extrusion or rolling processes. Their core characteristics include lightweight, high strength, corrosion resistance, and recyclability. Based on application areas, they can be categorized into nine main types: industrial profiles, building profiles, radiator profiles, automotive parts profiles, furniture profiles, photovoltaic profiles, rail vehicle profiles, mounting profiles, and medical profiles. Common alloy grades include 6063 and 6061. Different strength and corrosion resistance requirements can be achieved by adjusting the metal ratio. In industrial applications, aluminum profiles come in various specifications; for example, 4040 profiles are commonly used for equipment frames and fences, supporting customized mold making and precision machining. Compared to steel profiles, aluminum profiles have lower density and better corrosion resistance, but their strength depends on alloying treatment. They are suitable for lightweight applications such as transportation and electronic heat dissipation. In modern engineering, aluminum profiles often undergo surface treatments such as anodizing and fluorocarbon coating to enhance their performance, making them widely used in the construction, automotive, electronics, and new energy industries.

[0003] In existing aluminum profile splicing structures, the angle adjustment capability and splicing efficiency are often significantly insufficient. On the one hand, traditional structures can usually only achieve a limited number of fixed angle connections, lacking the ability to make continuous or multi-angle flexible adjustments, making it difficult to adapt to the needs of diverse installation scenarios. On the other hand, such structures often require tightening bolts one by one or relying on special tools during the assembly process, which is cumbersome and time-consuming, and cannot achieve quick disassembly and efficient locking, especially in applications that require frequent adjustments or large-scale assembly.

[0011] This utility model provides an aluminum profile splicing structure with angle positioning pins. It has the following beneficial effects:

[0012] 1. This aluminum profile splicing structure with angle positioning pins, through the setting of an adjustment and locking structure consisting of a central shaft, a threaded sleeve and angle positioning pins, cooperates with the first positioning holes and the second positioning holes distributed in a ring array, to achieve flexible multi-angle positioning and reliable locking of the second aluminum profile relative to the first aluminum profile.

[0019] 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.

[0020] like Figure 1-4As shown, this utility model provides an aluminum profile splicing structure with angle positioning pins, including a first aluminum profile 1 and a second aluminum profile 2. A first splicing component 3 is fixedly connected to the end of the first aluminum profile 1, and a second splicing component 4 is fixedly connected to the end of the second aluminum profile 2. The outer surface of the second splicing component 4 matches the groove of the first splicing component 3. An installation module 5 is provided inside the first splicing component 3 and the second splicing component 4. A fixing seat 19 is fixedly connected to one side of the first splicing component 3. A limiting rod 21 is sleeved inside the fixing seat 19, and a reset rod is sleeved outside the limiting rod 21. The spring 23 and the mounting module 5 include a central shaft 8. A first threaded sleeve 11 is rotatably connected to the outer surface of the central shaft 8. A second threaded sleeve 12 is threadedly connected to the outer surface of the first threaded sleeve 11. A connecting ring 13 is threadedly connected to the outer surface of the second threaded sleeve 12. A connecting block 14 is fixedly connected to the outer surface of the connecting ring 13. An angle positioning pin 15 is fixedly connected to the outer surface of the connecting block 14. A limit hole 16 is opened on the outer surface of the central shaft 8. A first positioning hole 17 is opened on the outer surface of the first splicing component 3. A second positioning hole 18 is opened on the outer surface of the second splicing component 4.

[0021] Specifically, the first splicing component 3 has a first central hole 6 inside, the second splicing component 4 has a second central hole 7 inside, the outer surface of the central shaft 8 is adapted to the interior of the first central hole 6 and the second central hole 7, and the central shaft 8 provides a stable rotational foundation and force core for the entire splicing structure.

[0022] Specifically, the first positioning holes 17 are arranged in a ring around the central axis of the first central hole 6, and the second positioning holes 18 are arranged in a ring around the central axis of the second central hole 7. The outer surface of the angle positioning pin 15 is adapted to the interior of the first positioning holes 17 and the second positioning holes 18. The function of the first positioning holes 17 and the second positioning holes 18 is to provide multiple circumferentially distributed angle positioning points, which facilitates the fixing of the second aluminum profile 2 at various angles relative to the first aluminum profile 1.

[0023] Specifically, the end of the first threaded sleeve 11 is fixedly connected to a handle 9, and the end of the central shaft 8 away from the handle 9 is provided with a tapered surface 10. The tapered surface 10 at the end of the central shaft 8 can guide and squeeze the limiting rod 21 during the insertion process, causing it to retract and make room. It is the key guide structure for realizing the automatic locking function of the central shaft 8.

[0024] Specifically, the fixed base 19 has an internal groove 20, and the limiting rod 21 passes through the internal groove 20. One end of the limiting rod 21 extends to the outside of the fixed base 19, and the other end extends to the inner cavity of the fixed base 19. The outer surface of the limiting rod 21 is adapted to the inside of the limiting hole 16. The cooperation between the limiting rod 21 and the limiting hole 16 constitutes the core locking mechanism. After it is inserted into the limiting hole 16, it can effectively prevent the central shaft 8 from moving axially and achieve reliable locking.

[0025] Specifically, a fixing plate 22 is fixedly connected to the outer surface of the limiting rod 21, one end of the return spring 23 is connected to the fixing plate 22, and the end of the return spring 23 away from the fixing plate 22 is fixedly connected to the inside of the inner groove 20. The return spring 23 provides a preload force to the limiting rod 21 toward the central axis 8, ensuring that when the limiting hole 16 is aligned, the limiting rod 21 can quickly and automatically spring in to complete the locking.

[0026] The working principle of the above embodiments:

[0027] When splicing two aluminum profiles, the second splicing piece 4 of the second aluminum profile 2 is inserted into the first splicing piece 3 of the first aluminum profile 1, aligning the first center hole 6 with the second center hole 7 and the first positioning hole 17 with the second positioning hole 18. Then, the central shaft 8 of the mounting module 5 is passed through the first center hole 6 and the second center hole 7 and inserted into the fixing seat 19. When the conical surface 10 of the central shaft 8 passes the limiting rod 21, it pushes the limiting rod 21 outward, compressing the return spring 23. When the limiting hole 16 moves to the limiting rod 21, under the elastic restoring force of the return spring 23, the limiting rod 21 is inserted into the limiting hole 16, thus locking the central shaft 8. Next, rotate the second aluminum profile 2 to the desired angle, and then rotate the handle 9 to rotate the first threaded sleeve 11, causing the second threaded sleeve 12 to move horizontally along the first threaded sleeve 11, causing the angle positioning pin 15 to be inserted into the corresponding first positioning hole 17 and second positioning hole 18, so that the second aluminum profile 2 is locked at the current angle. If the angle positioning pin 15 is offset from the nearest first positioning hole 17 before being inserted into the first positioning hole 17, rotate the second threaded sleeve 12 to adjust the angle positioning pin 15 to be aligned with its nearest first positioning hole 17, and then rotate the handle 9 to ensure that the angle positioning pin 15 can be accurately inserted.
