[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a photovoltaic bracket profile connection structure, mainly used to connect the uprights 5 and the horizontal tie beams 6 in a photovoltaic bracket, but it is not limited to this application scenario. It is also applicable to other fields involving profile connections, such as construction and industrial equipment. Figures 1 to 9 As shown, the photovoltaic bracket profile connection structure includes at least two clamps 1, which cooperate to form an annular structure for clamping the object to be fixed. The inner wall of the annular structure can adapt to the outer periphery of the object to be fixed. Each clamp 1 has a fixing part at both ends of its main body. During assembly, adjacent clamps 1 are fixedly connected by their respective fixing parts and fasteners 3.

[0033] The photovoltaic bracket profile connection structure has at least one transition part 2 on the outer side of its annular structure. The transition part 2 extends radially outward along the annular structure and is designed to support another object to be fixed, thereby achieving connection and fixation between different profiles. The transition part 2 has a U-shaped opening groove 21 in its middle. This U-shaped opening groove 21 not only provides excellent guidance, facilitating quick and accurate insertion and positioning of the profile to be connected, but also, after insertion, the two side walls of the U-shaped opening groove 21 can form a tight fit with the profile, providing stable support and fixation, effectively preventing the profile from shaking or shifting under stress, and ensuring the stability and reliability of the connection. Through this design, the photovoltaic bracket profile connection structure can effectively connect and integrate profiles in different directions and positions, greatly improving the overall stability and load-bearing capacity of photovoltaic brackets and other structures.

[0034] The ring structure formed by the clamps 1 can be a circular ring or a polygonal ring, etc. In this embodiment, there are two clamps 1, namely the first clamp 1-1 and the second clamp 1-2, and the inner wall of the two clamps 1 after enclosure is an octagonal ring structure, mainly to adapt to the octagonal column 5 profile. Specifically, the main body of a single clamp 1 is trapezoidal, which is composed of a top plate 11, a first side plate 12 and a second side plate 13 located at both ends of the top plate 11. Among them, the outer end of the first side plate 12 extends outward to form a first transition plate 14, and similarly, the outer end of the second side plate 13 extends outward to form a second transition plate 15. The included angle between each of the above adjacent plates is 135°, which enables the clamp 1 to fit perfectly with the octagonal column 5 profile, ensuring the tightness and stability of the connection.

[0035] Furthermore, the outer end of the first transition plate 14 extends outward to form a wing-shaped first fixing plate 16; the outer end of the second transition plate 15 also extends outward to form a second fixing plate 17. These fixing plates are all perpendicular to their corresponding transition plates. The fixing plates are provided with fixing holes 18 that mate with fasteners 3. By having the fasteners 3 pass through these fixing holes 18, adjacent clamps 1 can be securely connected together. When the two clamps 1 are closed, the first fixing plate 16 of one clamp 1 is spliced ​​together with the corresponding fixing plate of the other clamp 1 to form a structure equivalent to a top plate 11 or a side plate.

[0036] In this application, the different numbers and positions of the adapter parts 2 constitute different models of photovoltaic bracket profile connection structures. Manufacturers can pre-plan and manufacture photovoltaic bracket profile connection structures with different combinations of the number and position of the adapter parts 2 according to diverse actual assembly needs. In practical applications, operators only need to select the appropriate photovoltaic bracket profile connection structure based on the specific assembly scenario and functional requirements. The following are specific classifications and application descriptions of different photovoltaic bracket profile connection structures, including but not limited to the following categories:

[0037] ① Single-sided photovoltaic bracket profile connection structure: This model of connection component has one adapter 2, which is located on the main plate of one of the clamps 1. It is suitable for connecting the column 5 to its single-sided tie beam 6. (Refer to...) Figures 1 to 3 .

[0038] ② Straight-through photovoltaic bracket profile connection structure: This model of connecting component has two adapter parts 2, which are located on the main plates of the two clamps 1 and are on the same straight line. It is suitable for connecting the column 5 to the horizontal tie beams 6 on its opposite sides. (Refer to...) Figures 4 to 6 .

[0039] ③ Corner Photovoltaic Support Profile Connection Structure: This model of connecting component has two adapter parts 2, which are located on the two side plates of the same clamp 1, and are perpendicular to each other. It is suitable for connecting the column 5 located at a corner to the adjacent horizontal tie beams 6. (Refer to...) Figures 7 to 9 .

[0040] As a further optimization and improvement to the structure, in the connection design, the adapter 2 and the other object to be fixed are securely fixed using a U-shaped clamp 4. Figure 3 , Figure 6 and Figure 9 As shown, the U-shaped clamp 4 tightly fits around the outer periphery of the adapter 2 and the other object to be fixed in a wrapping manner. Through the elastic deformation of the U-shaped clamp 4 itself and the cooperation of fasteners 3 and other devices, a uniform and reliable clamping force is applied to the adapter 2 and the other object to be fixed, ensuring that the connection between the two is firm and stable, effectively preventing loosening or displacement caused by external forces or vibrations, and further improving the structural stability and safety of the entire photovoltaic bracket profile connection structure.

[0041] The fastener 3 described in this application can adopt a bolt and nut structure, which mainly consists of a bolt and a nut, and the two achieve a fastening connection function through threaded engagement.

[0042] The clamp 1 described in this application can be made of polymer materials, such as polyethylene, polypropylene, or polyvinyl chloride. Polymer materials have high plasticity and good processing performance; various complex shapes can be formed through simple injection molding and extrusion processes. Compared with existing solutions, the processing time is greatly shortened, and the procedures are simplified, which helps reduce labor costs. Furthermore, polymer materials have low density and are lighter than iron-based materials, making the product more convenient to transport and install. Polymer materials have good resistance to chemicals such as acids and alkalis, and their corrosion resistance is stronger than that of iron-based materials, enabling them to maintain long-term stable performance in harsh environments. At the same time, the production cost of polymer materials is lower, making them suitable for large-scale production.

With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
