The aluminum profile connection structure includes a connector, a support shaft, a rotating block, and an angle adjustment assembly. The connector has an internal cavity, within which the support shaft is connected. Two rotating blocks are symmetrically arranged, each rotatably connected to the support shaft; the rotating blocks are staggered at one end. The angle adjustment assembly is connected to the connector and includes a fixed component and a movable component. In this utility model, one rotating block can rotate around the support shaft as its center, adjusting the angle between the two rotating blocks, thereby adjusting the angle between the two aluminum profiles.

Even after the profile is fixed, its angle can still be adjusted.

Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to an aluminum profile connection structure and an aluminum profile assembly. Background Technology

[0002] Aluminum profiles are widely used in various fields of production and daily life due to their lightweight, corrosion resistance, and good ductility. Their product structures are diverse, including conventional products such as pipes and sheets, as well as regular or irregular components.

[0003] Chinese Patent No. CN221921590U discloses an aluminum profile connection structure, including a connector. The connector has a first bolt internally threaded onto its surface, and a connecting block is rotatably connected to the outer surface of the first bolt. One end of the connecting block is fixedly connected to an insert block. This aluminum profile connection structure, through the arrangement of the connecting block, insert block, spring, limiting post, and limiting hole, allows two connecting blocks to be rotatably connected to the outer surface of the first bolt. Loosening the first bolt allows for free rotation and adjustment, enabling the two insert blocks to be used for installing aluminum profiles at different angles. This enhances adjustability, allowing the angle of the two aluminum profiles to be adjusted after installation. Pressing the limiting post retracts it and the spring into the groove. Then, the insert block is inserted into the opening inside the aluminum profile. Under the elastic action of the spring, the limiting post engages with the limiting hole, fixing the insert block and completing the installation of the two aluminum profiles. This reduces installation difficulty and makes installation and disassembly more convenient.

[0004] However, in the above technical solution, only two connecting blocks are rotatably connected to the outer surface of the first bolt. Loosening the first bolt allows for free rotation and adjustment, making the two inserts suitable for installing aluminum profiles at different angles. This allows the angle of the two aluminum profiles to be adjusted after installation. However, during use, the spatial coupling relationship between the rectangular frame of the connector and the end face of the aluminum profile means that specific spatial avoidance conditions must be met during rotation adjustment. The angle adjustment must be completed before the inserts are fitted into the aluminum profile. After locking and fixing, it is difficult to make in-situ fine adjustments. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an aluminum profile connection structure and an aluminum profile assembly.

[0006] The technical solution of this utility model is as follows: An aluminum profile connection structure includes a connector with an internal cavity for receiving a support shaft connected within the cavity; two symmetrically arranged rotating blocks, each rotatably connected to the support shaft; and an angle adjustment assembly connected to the connector, comprising a fixed component and a movable component. The fixed component is connected to the rotating blocks, and the movable component is connected to the connector. The fixed component consists of an upper toothed plate and a lower toothed plate, which are respectively connected to the two rotating blocks on opposite sides. The movable component consists of a coaxial bidirectional screw, a movable toothed plate, and an adjustment block. The coaxial bidirectional screw is rotatably connected to the connector, and both ends of the coaxial bidirectional screw pass through the connector and are connected to the adjustment block. The adjustment block has an internal hexagonal groove. The symmetrically arranged movable toothed plates are connected to the coaxial bidirectional screw and engage with the upper and lower toothed plates. In use, the coaxial bidirectional screw drives the movable toothed plate to engage with the upper and lower toothed plates, restricting the rotation of the two rotating blocks around the support shaft.

[0007] Preferably, each of the internal hexagonal recesses is connected to a rubber stopper, and the rubber stopper is connected to a protrusion.

[0008] Preferably, the connector has two parallel mounting slots, each containing a permanent magnet, which is magnetically connected to a baffle.

[0009] Preferably, each rotating block has a threaded hole, through which bolts pass to connect with the profile.

[0010] Preferably, reference scales are provided on both sides of the connector, and indicator scales are provided on the rotating block.

[0011] Preferably, anti-slip pads are connected to both sides of the rotating block at the end away from the support shaft.

[0012] An aluminum profile assembly includes the aforementioned aluminum profile connection structure.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, a rotating block can rotate around a support shaft, and the included angle between two rotating blocks can be adjusted, thereby adjusting the angle between two aluminum profiles. The upper and lower toothed plates on the movable block can be fixed by the synchronous opposite movement of the movable toothed plates, restricting the rotation of the rotating block. After the profiles are fixed, their angles can also be adjusted. Attached Figure Description

The connector 1 has an internal cavity, within which the support shaft 2 is connected. Two rotating blocks 3 are symmetrically arranged, each rotatably connected to the support shaft 2; the rotating blocks 3 are staggered at one end. The angle adjustment assembly is connected to the connector 1 and includes a fixing member 4 and a movable member 5. The fixing member 4 is connected to the rotating block 3, and the movable member 5 is connected to the connector 1. The fixing member 4 consists of an upper toothed plate 6 and a lower toothed plate 7. The upper toothed plate 6 and the lower toothed plate 7 are... The movable part 5 is composed of a coaxial bidirectional screw 8, a movable toothed plate 9, and an adjusting block 10, which are connected to the two rotating plates on opposite sides. The coaxial bidirectional screw 8 is rotatably connected to the connector 1, and the two ends of the coaxial bidirectional screw 8 pass through the connector 1 and are connected to the adjusting block 10. The adjusting block 10 has an internal hexagonal groove. The symmetrically arranged movable toothed plates 9 are connected to the coaxial bidirectional screw 8 and cooperate with the upper toothed plate 6 and the lower toothed plate 7. When the angle adjustment component is in use, the coaxial bidirectional screw 8 drives the movable toothed plate 9 to cooperate with the upper toothed plate 6 and the lower toothed plate 7 to restrict the rotation of the two rotating plates around the support shaft 2.

[0022] Example 2

[0023] like Figures 2-4 As shown, this utility model proposes an aluminum profile connection structure and an aluminum profile assembly. Compared with Embodiment 1, this embodiment describes the detailed structure of the angle adjustment component.

[0024] In an optional embodiment, a rubber plug 11 is connected to each of the internal hexagonal recesses, and a protrusion is connected to the rubber plug 11; after the rubber plug 11 blocks the recess, it can prevent the problem of rotation caused by accidental contact by external objects.

[0025] In an optional embodiment, two parallel mounting slots are provided on the connector 1, and a permanent magnet 12 is connected in the mounting slot. The permanent magnet 12 is magnetically connected to a baffle 13. The baffle 13 can prevent debris from entering between the movable tooth plates 9, and can block impurities. It can also be replaced according to different angles to adapt to different environments.

[0026] In an optional embodiment, each of the rotating blocks 3 is provided with threaded holes, and bolts pass through the threaded holes to connect with the profile; the rotating blocks 3 are fixedly connected to the aluminum profile by bolts to prevent them from loosening and shaking;

[0027] In an optional embodiment, reference scales are provided on both sides of the connector 1, and indicator scales are provided on the rotating block 3; when the rotating block 3 rotates, the indicator scales on it will also rotate synchronously to facilitate personnel to check the current rotation angle.

[0028] In an optional embodiment, anti-slip pads 14 are connected to both sides of the rotating block 3 away from the support shaft 2; the anti-slip pads 14 are selected from, but are not limited to, rubber layers, and can play a preliminary positioning role before bolt connection.

[0030] like Figures 1-4 As shown, the present invention proposes an aluminum profile assembly, including the aluminum profile connection structure in Embodiment 1 or Embodiment 2.

[0031] In summary, when using this utility model, the operator inserts the two rotating blocks 3 into the cavities of the two aluminum profiles respectively, and then uses an Allen wrench to adjust the adjusting block 10 to drive the coaxial bidirectional screw 8 to rotate, so that the movable toothed plate 9 moves away from the upper toothed plate 6 and the lower toothed plate 7. At this time, the two rotating blocks 3 can rotate around the support shaft 2 to adjust their angle. The angle can be confirmed by the set indicator scale and reference scale or by external equipment. After the adjustment is completed, the coaxial bidirectional screw 8 is reversed, and the movable toothed plate 9 moves towards the upper toothed plate 6 and the lower toothed plate 7 on the opposite side to cooperate and restrict the rotation of the rotating blocks 3. Then, the bolt can be passed through the aluminum profile and the rotating blocks 3 to fix them, and the baffle 13 is magnetically connected to the permanent magnet 12. Finally, the rubber plug 11 is inserted into the groove of the adjusting block 10 to reduce external influence.
