Description

Technical Field

[0001] This utility model relates to the field of architectural aluminum profile technology, specifically to an adjustable angle architectural aluminum profile connecting bracket. Background Technology

[0002] In fields such as building curtain walls, interior decoration, exhibition displays, industrial equipment frames and intelligent warehousing systems, architectural aluminum profiles are widely used due to their lightweight, high strength, easy processing and aesthetics. These systems usually require multiple aluminum profiles to be assembled into a stable frame structure at specific angles using connectors.

[0003] However, existing aluminum profile connection technologies have significant technical limitations and application bottlenecks when facing complex, variable, or non-standard angle connection requirements. Currently, traditional aluminum profile connection methods mainly suffer from the following technical defects:

[0004] 1. The most common connection relies on prefabricated corner brackets or dedicated angle connectors. These connectors have fixed angles and cannot be adjusted once the design is finalized or the site conditions do not meet expectations. Special corner brackets must be customized or the profiles must be cut and processed in a complex manner. They also cannot adapt to the needs of temporary adjustments on site.

[0005] 2. A few adjustable-angle connectors on the market usually rely on the locking of a single bolt in the groove. This type of connection has the risk of loosening after adjustment, and has weak shear and torsional resistance, which cannot meet the application scenarios with high requirements for structural stability and load-bearing capacity. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable-angle building aluminum profile connecting bracket, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable-angle architectural aluminum profile connecting bracket includes: a connecting main sleeve, with a turntable 1 and a turntable 2 rotatably mounted at both ends of the connecting main sleeve, and internally connected rotating shafts rotatably mounted on the inner sides of the turntable 1 and the turntable 2, and a connecting component 2 fixedly connected to the outer side of the turntable 1, and a connecting component 1 fixedly connected to the outer side of the turntable 2, with a docking assembly fixedly mounted on the end faces of both the connecting component 1 and the connecting component 2, and an aluminum body mounted on the docking assembly; the turntable 1 and the turntable 2 are respectively provided with corresponding docking screw holes 1 and 2, with a fastening bolt 1 threaded into the internal thread of the docking screw hole 1, and a fastening bolt 2 threaded into the internal thread of the docking screw hole 2; the docking assembly includes a docking sleeve and plug-in parts, with a docking sleeve fixedly mounted on the end faces of both the connecting component 1 and the connecting component 2, and four sets of plug-in parts fixedly mounted inside the docking sleeve, the docking sleeve being used for limiting docking with the aluminum body through the plug-in parts.

[0009] Furthermore, the connecting component one includes a fixing sleeve one, a mounting base one, and a connecting seat one. The fixing sleeve one is fixedly mounted on the turntable two, the connecting seat one is fixedly mounted on the fixing sleeve one, and the mounting base one is fixedly mounted on the end face of the connecting seat one.

[0010] Furthermore, the second connecting component includes a second fixing sleeve, a second mounting base, and a second connecting seat. The second fixing sleeve is fixedly mounted on the first turntable, the second connecting seat is fixedly mounted on the second fixing sleeve, and the second mounting base is fixedly mounted on the end face of the second connecting seat.

[0011] Furthermore, the main connecting sleeve is provided with a limiting rotation groove, and the inner ends of both turntable one and turntable two are fixed with limiting rings, and the limiting rings are limited to the limiting rotation groove.

[0012] Furthermore, the docking assembly also includes positioning bolts. Three sets of detachable positioning bolts are fixed to the outer side of the plug-in, and the positioning bolts are threaded through the plug-in and extend into the aluminum body.

[0013] Furthermore, the first fastening bolt extends into the corresponding mating screw hole two and is connected by threads, and the second fastening bolt extends into the corresponding mating screw hole one and is connected by threads.

[0014] This utility model provides an adjustable-angle connecting bracket for architectural aluminum profiles. Compared with the prior art, it has the following advantages:

[0015] 1. The main sleeve, turntable one, and turntable two together form the core rotation hub of the bracket. The main sleeve serves as a fixed shell, providing rotational support and constraint space for the two turntables. Turntable one and turntable two serve as rotational carriers, respectively transmitting rotational motion to the aluminum profiles on both sides. This is the basis for achieving independent dual-axis, coaxial rotational adjustment.

[0016] As the internal rotating connecting shaft between the two turntables, it ensures that turntable one and turntable two can rotate smoothly, synchronously and interconnectedly around the same axis within the connecting main sleeve, and is the key internal structure for achieving precise angular coordination.

[0017] By setting corresponding screw holes on the two turntables and connecting them with bolts, a detachable rigid fixation is provided for the adjusted angle;

[0018] 2. Through the design of the mating sleeve and plug-in, it matches the inner cavity groove or standard section of the building aluminum profile to achieve precise radial positioning and anti-torsion; the positioning bolt provides axial locking force to prevent the aluminum profile from coming out of the sleeve when under tension or vibration, ensuring the long-term reliability of the connection.

[0035] Example

[0036] To address the technical problems in the background section, the following adjustable-angle architectural aluminum profile connection bracket is provided:

[0037] Combination Figures 1-5 As shown, the adjustable angle building aluminum profile connecting bracket provided by this utility model includes: a connecting main sleeve 100, with a turntable 600 and a turntable 800 rotatably installed at both ends of the connecting main sleeve 100 respectively, and an internal rotating shaft 700 rotatably installed on the inner side of the turntable 600 and the turntable 800 respectively, a connecting component 300 fixedly connected to the outer side of the turntable 600, a connecting component 200 fixedly connected to the outer side of the turntable 800, and a docking assembly 400 fixedly installed on the end face of the connecting component 200 and the connecting component 300 respectively, and an aluminum body 500 assembled on the docking assembly 400. Turntable 1 600 and turntable 2 800 are respectively provided with corresponding mating screw holes 1 601 and 2 801. The internal threads of mating screw hole 1 601 are connected to fastening bolt 1 602, and the internal threads of mating screw hole 2 801 are connected to fastening bolt 2 802. The mating assembly 400 includes mating sleeve 401 and plug-in 402. The end faces of connecting component 1 200 and connecting component 2 300 are both fixedly installed with mating sleeve 401. Four sets of plug-in 402 are fixedly installed inside the mating sleeve 401. The mating sleeve 401 is used to limit the mating with the aluminum body 500 through the plug-in 402.

[0038] In the above scheme: the bracket is a universal angle adjustment joint located at the connection of two aluminum profiles; its core is the connecting main sleeve 100, and its two ends are connected to the two aluminum profiles respectively through turntable 600 and turntable 800.

[0039] The two aluminum profiles can rotate independently around the axis of the connecting main sleeve, thereby adjusting the included angle between the two aluminum profiles in three-dimensional space. After adjustment, fastening bolt 602 and fastening bolt 802 pass through the mating screw hole 601 and mating screw hole 801 on the turntable respectively and lock them together, rigidly connecting the two turntables into one and fixing the angle.

[0040] The aluminum profile is connected to the bracket via the docking assembly 400, specifically by inserting it into the docking sleeve 401, and by the internal plug 402 engaging with the groove of the aluminum profile for positioning.

[0041] In this embodiment, the connecting component 200 includes a fixing sleeve 201, a mounting base 202, and a connecting seat 203. The fixing sleeve 201 is fixedly mounted on the turntable 800, the connecting seat 203 is fixedly mounted on the fixing sleeve 201, and the mounting base 202 is fixedly mounted on the end face of the connecting seat 203.

[0042] The connecting component 2 300 includes a fixing sleeve 2 301, a mounting base 2 302, and a connecting seat 2 303. The fixing sleeve 2 301 is fixedly mounted on the turntable 1 600, the connecting seat 2 303 is fixedly mounted on the fixing sleeve 2 301, and the mounting base 2 302 is fixedly mounted on the end face of the connecting seat 2 303.

[0043] The structure is symmetrical. The fixing sleeve 1 201 is fixed to the turntable 2 800 by interference fit or key connection. The connecting seat 1 203 is fixed to the fixing sleeve 1. The mounting base 1 202 serves as a base plate for fixing to the docking component.

[0044] It forms a transition and force transmission structure from the rotating component to the static connection interface; it converts the rotational motion of the turntable into the oscillation of the aluminum profile, and reliably transmits the load of the aluminum profile to the turntable and the connecting main sleeve.

[0045] In this embodiment, a limiting rotation groove 101 is provided inside the connecting main sleeve 100, and a limiting ring 900 is fixedly connected to the inner ends of both turntable 1 600 and turntable 2 800, and the limiting ring 900 is limitedly connected to the limiting rotation groove 101.

[0046] An annular limiting rotation groove 101 is machined on the inner wall of the connecting main sleeve 100. Limiting rings 900 are fixed on the inner end faces of turntable 600 and turntable 800 respectively, and the limiting rings are embedded in the limiting rotation groove.

[0047] To prevent the turntable from detaching from the connecting main sleeve when under force; the limiting ring rotates within the groove, ensuring the coaxiality and smoothness of the turntable's rotation.

[0048] In this embodiment, the docking assembly 400 also includes positioning bolts 403. Three sets of detachable positioning bolts 403 are fixed to the outer side of the plug-in 402, and the positioning bolts 403 are threaded through the plug-in 402 and extend into the aluminum body 500.

[0049] On the connector 402, the positioning bolt 403 is screwed in radially; after the aluminum profile is inserted into the mating sleeve, the positioning bolt is tightened, and its end can press against the inner wall of the aluminum profile or the special lock hole.

[0050] It provides a pull-out resistant locking mechanism between the aluminum profile and the mating sleeve; in addition to preventing radial movement during the plug-in fit, it adds axial tightening force to ensure that the connection will not loosen under vibration or stress, making the connection more reliable.

[0051] In this embodiment, fastening bolt 602 extends into the corresponding mating screw hole 801 and is connected by threads.

[0052] After the fastening bolt 602 passes through the mating screw hole 601 of the turntable 600, its threaded end continues to be screwed into the mating screw hole 801 of the turntable 800.

[0053] Conversely, fastening bolt 2 (802) passes through the mating screw hole 2 of turntable 2 and then screws into the mating screw hole 1 of turntable 1.

[0054] The two bolts are cross-interlocked, tightly pulling the two turntables together; this enhances the reliability of the locking and the shear resistance. Compared to a single bolt that only locks its own turntable, it can withstand greater torsional loads and prevent the angle from changing after being stressed.

[0055] Working principle and usage process of this utility model:

[0056] When aluminum profiles are being erected and installed, the connecting bracket works together on the two aluminum profiles, and the angle of the connection can be adjusted according to the actual erection requirements.

[0057] During this process, one end of the aluminum body 500 is connected to the docking sleeve 401. During the connection, the plug 402 in the docking sleeve 401 is inserted into the groove in the aluminum body 500 and fits with it. Then, another set of docking sleeves 401 is connected to another aluminum body 500. During the connection, the aluminum body 500 has screw holes for connecting with the positioning bolts 403.

[0058] After the two aluminum profiles are connected to their respective docking components 400, the angle of the two aluminum profiles can be adjusted by manipulating the two aluminum profiles with the bracket position as the center. The two aluminum profiles drive the turntable 600 and turntable 800 connected to them to rotate around the connecting main sleeve 100. The turntable 600 and turntable 800 rotate within the connecting main sleeve 100 through the built-in rotating shaft 700. The angle adjustment must meet the requirement that the docking screw hole 601 and the docking screw hole 801 correspond to each other.

[0059] After adjustment, the operator can align the first 602 bolt with the first 601 bolt hole. As the first 602 bolt is installed, it simultaneously enters the corresponding second 801 bolt hole. Similarly, after the second 802 bolt is aligned with the second 801 bolt hole, it also aligns with the first 601 bolt hole. In this way, the four sets of first 602 bolts and second 802 bolts respectively secure and lock the turntable 600 and turntable 800, completing the interconnection and adjustment of the two sets of aluminum profiles.
