Description

Technical Field

[0001] This utility model relates to the field of aluminum material assembly structure technology, and in particular to a large swing-leaf structure. Background Technology

[0002] The large swing structure in aluminum is a common design for connecting and moving parts in doors, windows, cabinets and other fields. Its core is to achieve a large-angle, stable and durable swing function through the reasonable construction of aluminum.

[0003] Currently, small-sized hinges are integrally extruded and are generally hollow single-layered. However, this type of hinge structure is only suitable for small doors, windows, and cabinet structures. Large hinges are generally assembled from multiple aluminum materials, but the existing large hinge structure has the following defects: there is a lack of effective connection between the main frame and the two curved frames at both ends. Generally, after simple butt jointing, the main frame and the two curved frames at both ends are fixed to the sealing plates with bolts. Although this fixation can meet the connection requirements, the stability of the connection between the main frame and the two curved frames at both ends will decrease with the influence of the external environment during use, resulting in noise and abnormal sounds in strong winds. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, specifically the problem of unstable connection between the main frame and the two curved frames of the large swing-leaf structure, which easily leads to noise and abnormal sounds in windy weather. This invention provides an improved aluminum structure for the large swing-leaf structure with a more stable and reliable connection, thereby improving the performance and service life of the large swing-leaf.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-page-swinging structure includes a main frame and an arc-shaped frame. The arc-shaped frame has two clips attached to both sides of the main frame. Both ends of the main frame and the arc-shaped frame are connected to sealing end plates. The main frame has an opening at the end corresponding to the arc-shaped frame. The opening has a first clip frame on both sides. The end of the first clip frame facing the arc-shaped frame has a first triangular connecting piece.

[0007] The arc-shaped frame body is provided with a connecting frame at the end corresponding to the main frame body. A second snap-fit ​​frame is provided on the connecting frame facing the first snap-fit ​​frame. The end of the second snap-fit ​​frame is provided with a second triangular docking piece corresponding to the first triangular docking piece. The arc-shaped frame body is provided with an outer connecting part along the outer side of the end corresponding to the main frame body. The outer connecting part is integrally provided with a pressing part facing the first snap-fit ​​frame. When the bolt is connected inside the outer connecting part, the expansion causes the pressing part to abut against the first snap-fit ​​frame.

[0008] Furthermore, the two sides of the main frame are curved and are in contact with the outer side of the curved frame.

[0009] Furthermore, both the main frame and the arc-shaped frame are equipped with several support frames inside, and the support frames are provided with an internal connection part at one side of the included angle between the main frame and the arc-shaped frame.

[0010] Furthermore, the size of the sealing end plate is adapted to the size of the main frame and the arc-shaped frame after docking. The sealing end plate is provided with screw mounting holes, and the sealing end plate is fixed to the main frame and the arc-shaped frame by connecting the outer connecting part or the inner connecting part through the screw mounting holes.

[0011] Furthermore, the outer side of the sealing end plate is provided with a shaft hole in the center, through which a rotating shaft is installed and connected to the door and window swing mechanism.

[0012] Furthermore, the second triangular docking member abuts against the first triangular docking member, the first triangular docking member contracts to cause the second triangular docking member to engage, and the first triangular docking member resets to prevent the second triangular docking member from disengaging.

[0013] Furthermore, the main frame, the arc-shaped frame, and the sealing end plate are all made of extruded aluminum profiles.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] I. Significantly improved connection stability

[0016] 1) Double Triangular Connecting Structure: The first triangular connecting piece at the opening of the main frame and the second triangular connecting piece of the arc-shaped frame connecting frame form a tenon-and-mortise connection. When the arc-shaped frame is inserted into the main frame, the inclined surface of the second triangular connecting piece squeezes the first triangular connecting piece, causing it to shrink. When fully inserted, the first triangular connecting piece elastically resets and firmly locks the second triangular connecting piece, forming a self-locking effect. This design avoids the loosening problem of traditional simple connections and can effectively prevent the main frame from separating from the arc-shaped frame, even in strong winds or frequent swaying.

[0017] 2) Coordinated reinforcement of external connection and compression parts: When the external connection parts on the outside of the arc-shaped frame are connected by bolts, the internal structure will expand slightly due to the tightening of the bolts, which will drive the compression part to apply pressure to the first snap-fit ​​frame of the main frame. This pressure further strengthens the fit between the contact surface of the main frame and the arc-shaped frame, eliminating the singleness of traditional bolt fixing that only relies on end face connection, forming a dual fixing mode of "snap-fit ​​+ compression", which significantly improves the vibration resistance and shear resistance.

[0018] In summary, traditional structures suffer from loose connections that cause metal parts to rub or collide during swinging. This invention, however, eliminates minute gaps between components through the tight fit of the double triangular interlocking and pressing parts. Even in windy conditions, the connection between the main frame and the arc-shaped frame remains highly fitted, preventing abnormal noises caused by shaking. It fundamentally solves the problems of unstable connections and noise generation in traditional large swing-leaf designs, significantly improving performance and service life, and is suitable for scenarios with high requirements for stability and durability.

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a large swing-page structure, mainly including a main frame 1 and an arc-shaped frame 2, wherein there are two arc-shaped frames 2, which are respectively snapped onto both sides of the main frame 1. Both ends of the main frame 1 and the arc-shaped frame 2 are connected to sealing end plates 3. The sealing end plates 3 play the role of sealing and protecting the internal structure, while providing a certain rigidity and stability for the overall structure; the main frame 1, the arc-shaped frame 2 and the sealing end plates 3 are all made of aluminum extrusion profiles.

[0034] The main frame 1 has an opening 11 at the end corresponding to the arc-shaped frame 2. The design of the opening 11 facilitates the docking and installation of the arc-shaped frame 2 and the main frame 1. The two sides of the opening 11 are provided with first snap-fit ​​brackets 12. The first snap-fit ​​brackets 12 are important components for connecting the main frame 1 and the arc-shaped frame 2. The end of the first snap-fit ​​bracket 12 is provided with a first triangular docking piece 13 facing the arc-shaped frame 2. The special shape design of the first triangular docking piece 13 helps to achieve a stable snap-fit ​​effect.

[0035] A connecting frame 21 is provided at the end of the arc-shaped frame 2 corresponding to the main frame 1. The connecting frame 21 is the basic structure for connecting the arc-shaped frame 2 and the main frame 1. A second locking frame 22 is provided on the connecting frame 21 facing the first locking frame 12. The second locking frame 22 cooperates with the first locking frame 12 to achieve the initial positioning and connection of the arc-shaped frame 2 and the main frame 1. A second triangular docking piece 23 is provided at the end of the second locking frame 22 corresponding to the first triangular docking piece 13. The docking design of the second triangular docking piece 23 and the first triangular docking piece 13, through a specific shape fit, ensures that the two can be firmly locked together after docking, preventing loosening and separation.

[0036] The arc-shaped frame 2 is provided with an outer connecting part 24 along the outer side of the main frame 1. The outer connecting part 24 provides an installation position for the connecting bolts. The outer connecting part 24 is integrally provided with a pressing part 25 facing the first snap-fit ​​frame 12. When the bolt is connected in the outer connecting part 24, the outer connecting part 24 will expand as the bolt is tightened. The force of the expansion makes the pressing part 25 abut against the first snap-fit ​​frame 12, which further enhances the connection strength between the main frame 1 and the arc-shaped frame 2 and ensures the stability of the entire large swing-page structure.

[0037] Example 2

[0038] like Figure 1-4 As shown, the two sides of the main frame 1 are curved and connect with the outer side of the curved frame 2. This curved surface design not only makes the overall structure more beautiful, but also disperses stress to a certain extent and improves the load-bearing capacity of the structure.

[0039] Both the main frame 1 and the arc-shaped frame 2 are equipped with several support frames 4 inside. The support frames 4 play a role in enhancing the internal structural strength of the main frame 1 and the arc-shaped frame 2, enabling them to withstand greater external forces. An inner connection part 5 is provided at one side of the included angle between the support frame 4 and the main frame 1 and the arc-shaped frame 2. The inner connection part 5 provides an additional fixing point for the connection of the sealing end plate 3, further enhancing the stability of the entire structure.

[0040] The sealing end plate 3 is sized to match the dimensions of the main frame 1 and the arc-shaped frame 2 after they are joined, ensuring that the sealing end plate 3 can fit tightly against both ends of the main frame 1 and the arc-shaped frame 2, thus providing a good seal. The sealing end plate 3 is provided with screw mounting holes 31, through which the outer connecting part 24 or the inner connecting part 5 is connected, thereby realizing the fixed connection between the sealing end plate 3 and the main frame 1 and the arc-shaped frame 2. This connection method is simple and reliable, and is easy to install and disassemble.

[0041] The outer side of the sealing end plate 3 is provided with a shaft hole 32 in the center. The shaft hole 32 is a key part for connecting the door and window swing mechanism. The shaft is installed through the shaft hole 32, so that the large swing structure can be flexibly rotated and connected with the door and window swing mechanism, thereby realizing the swing function of the door and window.

[0042] When the second triangular connector 23 abuts against the first triangular connector 13, the first triangular connector 13 will contract under the action of external force, so that the second triangular connector 23 can be smoothly inserted. After being inserted, the first triangular connector 13 is reset. Its special shape and structure can prevent the second triangular connector 23 from disengaging, ensuring that the connection between the main frame 1 and the arc-shaped frame 2 is firm and reliable.

[0043] The working process of this utility model is as follows: When using a large swing-page structure, the main frame 1 and the arc-shaped frame 2 are initially connected. The two arc-shaped frames 2 are placed on both sides of the main frame 1, so that the second snap-fit ​​frame 22 on the connecting frame 21 of the arc-shaped frame 2 is aligned with the first snap-fit ​​frame 12 on both sides of the opening 11 of the main frame 1. The arc-shaped frame 2 is slowly pushed so that the second triangular connecting piece 23 and the first triangular connecting piece 13 abut against each other. With the continuous action of external force, the first triangular connecting piece 13 retracts and the second triangular connecting piece 23 is smoothly snapped in. After it is snapped in place, the first triangular connecting piece 13 is reset to prevent the second triangular connecting piece 23 from disengaging. At this time, the main frame 1 and the arc-shaped frame 2 are initially connected.

[0044] Then install the sealing end plate 3, placing it at both ends of the main frame 1 and the arc-shaped frame 2 after they are joined. Align the screw mounting holes 31 on the sealing end plate 3 with the screw holes on the outer connecting part 24 and the inner connecting part 5, respectively. Use screws to fix the sealing end plate 3 to the outer connecting part 24 or the inner connecting part 5 through the screw mounting holes 31, ensuring that the sealing end plate 3 fits tightly against both ends, providing good sealing and fixing. At the same time, as the bolts are tightened, the outer connecting part 24 expands, and the squeezing part 25 gradually contacts the first snap-fit ​​bracket 12. This squeezing action further enhances the connection strength between the main frame 1 and the arc-shaped frame 2, ensuring that the connection between the two is firm and stable.

[0045] Finally, connect the door and window swing mechanism by installing the appropriate rotating shaft into the shaft hole 32 on the outer side of the sealing end plate 3, and connect and fix the other end of the rotating shaft to the door and window swing mechanism. After the connection is completed, check whether the installation of the entire large swing structure is firm, whether the connection between each component is tight, and whether the rotation is flexible. After confirming that there are no errors, the large swing structure can be put into use with the door and window system.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
