[0034] See Figures 1 to 7 As shown, this utility model embodiment provides a multi-angle connection mechanism, including: a first connector 1, a second connector 2, and a positioning member 3. The first connector 1 is used to connect the building body 4, and the second connector 2 is used to connect the curtain wall unit. The first connector 1 is rotatably connected to the second connector 2. The first connector 1 is provided with adjustment structures 11 at multiple angles. The positioning member 3 is detachably connected to any adjustment structure 11 and detachably connected to the second connector 2 to adjust and lock the connection angle between the first connector 1 and the second connector 2.

[0035] Specifically, by setting up three core structures—a first connector 1, a second connector 2, and a positioning component 3—the functional positioning and connection relationship of each component are clearly defined. The first connector 1 is specifically used to connect and fix the main building 4, while the second connector 2 is specifically used to connect the curtain wall unit. The two are connected by rotation to achieve relative angle adjustment. The first connector 1 has multiple pre-set adjustment structures 11 for different angles. The positioning component 3 adopts a detachable design, remaining detached from both the first connector 1 and the second connector 2 during the angle adjustment phase. After the second connector 2 rotates to the target angle, the positioning component 3 is detachably connected to the adjustment structures 11 and the second connector 2, establishing an angle locking mechanism to ensure that the connection angle can be adjusted and fixed as needed.

[0036] This embodiment, through the ingenious design of the adjustment structure 11 and the detachable positioning component 3, successfully breaks the limitation of the traditional connection structure that "adjustment must be disassembled". It enables the first connecting component 1 and the second connecting component 2 to maintain a rotating connection, and the connection angle can be adjusted and fixed by docking the positioning component 3 with the adjustment structure 11 at different angles. This directly realizes the adjustment of the curtain wall installation angle under the continuous connection between the building body 4 and the curtain wall unit. This design makes the connection between the curtain wall unit and the building body 4 adjustable. The multiple adjustment structures 11 pre-set on the first connector 1 cover the common multi-angle requirements of curtain wall installation, which can meet the needs of fine adjustment of flat curtain walls or specific angle adaptation of irregular curtain walls. It also eliminates the tedious steps of repeatedly disassembling the connection structure between the building body 4 and the curtain wall unit during adjustment. Especially in the case of high-altitude curtain wall installation, the posture calibration can be completed directly in the connected state, which greatly shortens the construction time and greatly enhances convenience. In addition, it fundamentally ensures the safety of operation. During the adjustment process, the curtain wall unit is always firmly connected to the building body 4 through the multi-angle connection mechanism, which completely avoids the risk of falling caused by temporary disassembly and storage or suspension of the curtain wall unit. The tight connection between the positioning component 3 and the adjustment structure 11 can ensure the stability of the overall structure after the angle is locked, effectively resisting the influence of external forces such as wind load.

[0037] In one specific embodiment, the multi-angle connection mechanism further includes a connecting shaft 5. The first connecting member 1 and the second connecting member 2 are respectively provided with a first shaft hole 12 and a second shaft hole 21. The connecting shaft 5 extends into the first shaft hole 12 and the second shaft hole 21 so that the first connecting member 1 and the second connecting member 2 form a rotatable connection. A plurality of adjustment structures 11 are distributed on the same arc line centered on the first shaft hole 12.

[0038] Specifically, this embodiment adds a connecting shaft 5, and by opening a first shaft hole 12 and a second shaft hole 21 on the first connecting member 1 and the second connecting member 2 respectively, the structural design of the connecting shaft 5 extending into the two shaft holes enables the first connecting member 1 and the second connecting member 2 to form a precise and stable rotational connection. Multiple adjustment structures 11 are distributed on the same arc line centered on the first shaft hole 12, ensuring that when the second connecting member 2 rotates relative to the first connecting member 1 to different angles, each adjustment structure 11 can always maintain a dockable positional relationship with the positioning member 3, providing a precise structural basis for angle adjustment.

[0039] This embodiment significantly improves the coaxiality and stability of the rotational connection between the first connector 1 and the second connector 2 through the mating structure of the connecting shaft 5 and the shaft hole, avoiding offset and wobbling during the rotation of the second connector 2; the arc distribution design of the adjustment structure 11 is adapted to the fixed state of the first connector 1, making the positioning of the angle adjustment more precise. Each adjustment structure 11 corresponds to a specific rotation angle, effectively reducing adjustment errors, while simplifying the docking operation between the positioning part 3 and the adjustment structure 11, further improving installation efficiency.

[0040] In one specific embodiment, the positioning member 3 is provided with a positioning structure 31, the adjustment structure 11 is a first arc-shaped rack, the positioning structure 31 is a second arc-shaped rack, and the first arc-shaped rack meshes with the second arc-shaped rack.

[0041] Specifically, the adjustment structure 11 is designed as a first arc-shaped rack, and the positioning structure 31 on the positioning member 3 is designed as a second arc-shaped rack. The angle adjustment and locking are achieved by utilizing the meshing structure of the racks. Through the meshing of the arc-shaped racks, not only can multi-position angle positioning be achieved, but also a stable mechanical locking can be formed by the mutual biting action between the teeth, preventing loosening and displacement after angle adjustment, and adapting to the arc-shaped motion trajectory of the first connecting member 1 being fixed and the second connecting member 2 rotating around the axis.

[0042] Compared to ordinary structures, this arc-shaped rack and pinion meshing design significantly improves the stability and reliability of angle locking. The meshing between the teeth can effectively resist the rotation tendency of the second connector 2 under external force. At the same time, the rack and pinion structure can achieve finer angle grading, making the angle adjustment more precise and meeting the stringent requirements of curtain wall construction scenarios with strict installation angle requirements. Moreover, the disassembly and docking of the meshing structure is simple and does not affect the adjustment efficiency.

[0043] In one specific embodiment, the teeth (not shown in the figure) of the first arc-shaped rack are distributed on the convex side of the first arc-shaped rack, and the teeth (not shown in the figure) of the second arc-shaped rack are distributed on the concave side of the second arc-shaped rack.

[0044] Specifically, the teeth of the first arc-shaped rack are distributed on its convex side, and the teeth of the second arc-shaped rack are distributed on its concave side. Through the adaptive design of the teeth on the convex and concave sides, a tighter fit can be formed when they mesh. This tooth distribution method matches the relative motion trajectory of the first connecting member 1 being fixed and the second connecting member 2 rotating, ensuring that the teeth can be accurately aligned and engaged during meshing, while increasing the meshing contact area and improving the stability of transmission and locking.

[0045] This tooth distribution design on the convex and concave sides optimizes the meshing effect, making the force between the teeth more uniform, reducing the load on individual teeth, and extending the service life of the structure. The tight meshing relationship further enhances the firmness of the angle locking, effectively preventing meshing loosening caused by vibration and other factors during long-term use, while improving the smoothness of rack meshing and disengagement and reducing operating resistance.

[0046] In one specific embodiment, multiple adjustment structures 11 are continuously distributed on the same arc line centered on the first shaft hole 12.

[0047] Specifically, multiple adjustment structures 11, i.e., the first arc-shaped rack, are continuously distributed on the same arc line centered on the first shaft hole 12, forming a complete arc-shaped rack structure. This continuous distribution method breaks the angular interval limitation of the discrete adjustment structures 11, adapts to the adjustment logic of the first connector 1 being fixed and the second connector 2 being rotated, and allows the rotation angle of the second connector 2 to be arbitrarily adjusted within a continuous range, rather than being limited to a specific gear angle, thus adapting to more diverse installation angle requirements.

[0048] This embodiment achieves stepless angle adjustment through this continuously distributed arc-shaped rack, which greatly expands the application range of the multi-angle connection mechanism and can meet the installation requirements of curtain walls with various non-standard angles. At the same time, the design of the continuous rack simplifies the structural processing of the first connector 1, eliminating the need to process multiple discrete adjustment structures 11, reducing manufacturing difficulty and cost, and the arbitrary angle adjustment method makes the installation operation more flexible and convenient.

[0049] It is understood that in other embodiments, the adjustment structure 11 can be set as a first connecting hole (not shown in the figure) on the first connecting member 1, with multiple first connecting holes distributed on the same arc line centered on the first shaft hole 12. The second connecting member 2 is provided with a second connecting hole (not shown in the figure), and the positioning member 3 is a connecting rod (not shown in the figure). The connecting rod extends into and connects to the second connecting hole and any of the first connecting holes to realize the angle adjustment and fixation of the first connecting member 1 and the second connecting member 2. The hole structure is easy to process, low in cost, and compatible with standardized processes. The distribution centered on the first shaft hole 12 ensures that the first connecting hole and the second connecting hole are accurately aligned after angle adjustment, and the connecting rod can quickly fix the two, ensuring connection reliability. At the same time, the matching of the hole and the rod is suitable for various locking scenarios, and the structure has little wear, can maintain positioning accuracy for a long time, and improves the practicality and durability of the multi-angle connection mechanism.

[0050] In one specific embodiment, the first connecting member 1 includes a first connecting plate 13, the second connecting member 2 includes a limiting plate 22, the sidewall of the first connecting plate 13 abuts against the limiting plate 22, the first shaft hole 12 and the second shaft hole 21 are respectively provided in the first connecting plate 13 and the limiting plate 22, and the connecting shaft 5 extends into the first shaft hole 12 and the second shaft hole 21 so that the first connecting plate 13 and the limiting plate 22 form a rotatable connection.

[0051] Specifically, this embodiment refines the structure of the first connecting member 1 and the second connecting member 2. The first connecting member 1 includes a first connecting plate 13, and the second connecting member 2 includes a limiting plate 22. The abutting fit between the side wall of the first connecting plate 13 and the limiting plate 22 provides lateral limiting for the relative movement of the first connecting member 1 being fixed and the second connecting member 2 being rotated. The first shaft hole 12 and the second shaft hole 21 are respectively provided in the first connecting plate 13 and the limiting plate 22, so that the connecting shaft 5 can accurately connect the two plates, forming a rotating structure centered on the shaft hole, ensuring the stability and coaxiality of the second connecting member 2 during rotation.

[0052] The abutment structure between the first connecting plate 13 and the limiting plate 22 effectively restricts the relative displacement of the second connecting piece 2 in the lateral direction, improves the stability of the rotational connection, avoids shaking or offset during angle adjustment, and ensures adjustment accuracy. The design of setting the shaft holes on the two plates respectively makes the structural layout more reasonable, facilitates processing and assembly, and enhances the structural strength of the first connecting piece 1 and the second connecting piece 2, thereby improving the overall load-bearing capacity.

[0053] Preferably, the connecting shaft 5 is a pig-nose bolt. Pig-nose bolts are easy to install and have reliable positioning, enabling quick rotational connection between the first connecting member 1 and the second connecting member 2. At the same time, their heads can play a certain limiting role to prevent the connecting shaft 5 from falling off. Using standardized pig-nose bolts as the connecting shaft 5 reduces procurement costs and facilitates replacement and maintenance, thereby improving the economy and practicality of the multi-angle connection mechanism.

[0054] In one specific embodiment, the positioning member 3 and the first connecting plate 13 are located on the same side of the limiting plate 22 and both abut against the limiting plate 22. The adjusting structure 11 is located at the end of the first connecting plate 13 near the positioning member 3. The positioning structure 31 is oriented toward the adjusting structure 11 and abuts against the adjusting structure 11. The positioning member 3 is detachably connected to the limiting plate 22.

[0055] Specifically, the installation position relationship between the positioning component 3 and the first connecting plate 13 is clearly defined. Both are located on the same side of the limiting plate 22 and abut against the limiting plate 22, forming a compact assembly structure that fits snugly against the limiting plate 22. The adjusting structure 11 is located at the end of the first connecting plate 13 near the positioning component 3. The positioning structure 31 is positioned facing the adjusting structure 11 and abuts against it, ensuring that when the first connecting component 1 is fixed, the two can accurately align after the second connecting component 2 is rotated. The detachable connection between the positioning component 3 and the limiting plate 22 provides fixed support for angle locking.

[0056] The design of the positioning component 3 and the first connecting plate 13 being attached to the limiting plate 22 on the same side makes the overall structure more compact, reduces the space occupied by the multi-angle connection mechanism, and is suitable for the narrow space scenario of curtain wall installation; the orientation of the positioning structure 31 and the adjustment structure 11 is designed to match the fixed state of the first connecting component 1, ensuring the accuracy of engagement or docking and reducing the difficulty of operation; the positioning component 3 is directly connected to the limiting plate 22, which shortens the force transmission path and improves the stability and load-bearing capacity of the locking structure.

[0057] In one specific embodiment, the second connector 2 is further provided with a mounting base 23, two limiting plates 22 are arranged in parallel to each other and connected to the mounting base 23, the two sides of the first connecting plate 13 and the positioning member 3 respectively abut against the two limiting plates 22, and the first connecting plate 13 is located at the end of the limiting plate 22 away from the mounting base 23, and the positioning member 3 is located between the mounting base 23 and the first connecting plate 13.

[0058] Specifically, this embodiment further optimizes the second connecting member 2 by adding a mounting base 23 and two parallel limiting plates 22. The two limiting plates 22 are connected to the mounting base 23 to form a symmetrical limiting structure. The two sides of the first connecting plate 13 and the positioning member 3 respectively abut against the two limiting plates 22 to form double-sided limiting. At the same time, the axial positions of the first connecting plate 13 and the positioning member 3 are clearly defined. The first connecting plate 13 is located at the end away from the mounting base 23, and the positioning member 3 is located between the mounting base 23 and the first connecting plate 13, making the structural layout more orderly and adapting to the adjustment requirements of fixing the first connecting member 1 and rotating the second connecting member 2.

[0059] The structure of the parallel double-sided limiting plate 22 forms a more reliable lateral limiting, completely avoiding lateral displacement during the rotation of the second connecting piece 2 and the adjustment of the positioning piece 3, and significantly improving the assembly accuracy and stability; the mounting base 23 provides a stable mounting foundation for the second connecting piece 2, and the orderly axial position layout makes the force on each component more balanced, enhancing the load-bearing capacity of the overall structure.

[0060] In one specific embodiment, the limiting plate 22 and the mounting base 23 are integrally formed.

[0061] Specifically, the one-piece molding structure eliminates the connection gap 6 and assembly error between the limiting plate 22 and the mounting base 23, improves the overall structural strength and rigidity of the second connector 2, and makes the structure more stable under stress. At the same time, it reduces assembly steps, reduces assembly difficulty and cost, improves production efficiency, and the one-piece structure has better sealing performance, which can effectively prevent dust, rainwater and other substances from entering the interior and affecting the performance of the components.

[0062] In one specific embodiment, a gap 6 is provided between the positioning member 3 and the mounting base 23.

[0063] Specifically, a gap 6 is provided between the positioning element 3 and the mounting base 23. This gap 6 provides the necessary movement space for the positioning element 3, preventing interference between the positioning element 3 and the mounting base 23 when the first connecting element 1 is fixed, the second connecting element 2 is rotated, and the positioning element 3 is adjusted. When it is necessary to adjust the positioning element 3 to mate with the adjustment structure 11 or to disassemble the positioning element 3 for angle adjustment, the gap 6 can accommodate the axial movement of the positioning element 3, ensuring smooth operation and avoiding wear caused by hard contact between parts.

[0064] The specific adjustment process is as follows: the first connecting piece 1 is fixed to the building body 4. When it is necessary to align the positioning piece 3 with the adjustment structure 11, the positioning piece 3 is moved towards the first connecting plate 13, and the gap 6 between the positioning piece 3 and the mounting base 23 is reduced, so that the positioning structure 31 can smoothly engage with the adjustment structure 11. When it is necessary to disassemble the positioning piece 3 for angle adjustment, the positioning piece 3 is moved towards the mounting base 23, and the gap 6 is used to separate the positioning structure 31 from the adjustment structure 11. Then the second connecting piece 2 can be rotated to adjust the angle.

[0065] This embodiment effectively solves the interference problem during the movement of the positioning component 3 by setting the gap 6, making the docking and separation operation of the positioning component 3 smoother and more convenient, and reducing the difficulty of installation and maintenance; at the same time, it avoids direct contact and friction between the positioning component 3 and the mounting base 23, reduces the wear of parts, extends the service life of the multi-angle connection mechanism, and also provides a buffer space for the thermal expansion and contraction of the structure caused by temperature changes.

[0066] In one specific embodiment, the multi-angle connection mechanism further includes a locking member 7, which is detachably connected to the positioning member 3 and the second connecting member 2.

[0067] Specifically, the locking component 7 is detachably connected to the positioning component 3 and the limiting plate 22, making the connection between the two more secure and effectively resisting loosening under the action of external forces such as the load of the curtain wall unit, significantly improving the stability and reliability of the angle locking; the detachable feature of the locking component 7 allows the positioning component 3 to be easily separated from the limiting plate 22 for angle adjustment, taking into account both the firmness of the connection and the flexibility of adjustment, adapting to the needs of multiple scenarios in the curtain wall installation process.

[0068] Preferably, the locking element 7 is a machine-made screw, and the number of locking elements 7 is at least two. Machine-made screws have high connection strength and good self-locking performance, which can effectively ensure the connection stability between the positioning element 3 and the second connecting element 2; the setting of at least two machine-made screws makes the connection force more even, avoids stress concentration caused by single-point connection, further improves the reliability and load-bearing capacity of the connection, and adapts to the large load requirements of the curtain wall unit. It is understood that in other embodiments, the locking element 7 can also be a bolt or other locking structure.

[0069] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
