After repeated use, under the external force of repeated squeezing and fastening, stress concentration is likely to occur at the straight reinforcement structure at the corner of the fastener, which leads to material fatigue and cracks. This causes the fastener to be damaged prematurely and cannot continue to be used normally, thus affecting the fixing effect of the solar panel. Summary of the Invention

[0005] The purpose of this application is to provide a fastener for fixing solar panels, which can solve the technical problems mentioned in the background art.

[0006] This application provides a fastener for fixing a solar panel, including a connecting part for connecting with a bolt. The connecting part has fastening parts integrally formed and symmetrically arranged on both sides.

[0007] Furthermore, the distance from the protruding end of the limiting protrusion to the inner side of the fastening part is greater than the distance from the protruding end of the hook to the inner side of the fastening part.

[0008] Furthermore, the bottom of the connecting part is integrally formed with a reinforcing protrusion.

[0009] Furthermore, the connecting part is provided with a threaded hole that matches the bolt, and the threaded hole penetrates the reinforcing protrusion.

[0010] Furthermore, the cross-section of the reinforcing protrusion is an inverted isosceles trapezoid.

[0011] Furthermore, the included angle between the upper end of the fastening part and the bottom of the connecting part is 100° to 140°.

[0012] Furthermore, the surface of the fastener is provided with an anti-corrosion layer.

[0013] The beneficial effects of this utility model are:

[0014] Compared with the prior art, this utility model eliminates the straight reinforcement structure, which increases the deformability between the upper end of the fastening part and the connecting part when the fastener is pressed and fastened.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0028] like Figure 2and Figure 3 As shown, this application provides a fastener for fixing a solar panel, including a connecting part 1 for connection with bolts. The connecting part 1 has symmetrically integrally formed fastening parts 2 on both sides. The angle between the upper end of the fastening part 2 and the bottom of the connecting part 1 is an obtuse angle. The lower end of the fastening part 2 has an inwardly bent hook 3. The inner side of the fastening part 2, above the hook 3, has a limiting protrusion 4. In use, this fastener replaces the fastener in a solar panel fixing device disclosed in CN222016435U. Compared with the prior art, the straight reinforcement structure is eliminated, increasing the deformability between the upper end of the fastening part 2 and the connecting part 1 during compression fastening installation. This allows for better fastening during installation, reducing material fatigue and cracking, preventing premature damage to the fastener, extending its service life, and ensuring the fixing effect of the solar panel.

[0029] like Figure 2 and Figure 3 As shown, the distance from the protruding end of the limiting protrusion 4 to the inner side of the fastening part 2 is greater than the distance from the protruding end of the hook 3 to the inner side of the fastening part 2. During the fastening installation process, the limiting protrusion 4 and the hook 3 play a role in different positions, forming a multi-layered fixing structure. The limiting protrusion 4 limits the guide rail that is fastened and inserted, ensuring that the installation position is appropriate and ensuring the stability of the installation structure.

[0030] like Figure 2 and Figure 3 As shown, the bottom of the connecting part 1 is integrally formed with a reinforcing protrusion 5. The reinforcing protrusion 5 can increase the thickness and cross-sectional area of ​​the connecting part 1, so that it has stronger compressive and tensile strength when connected with bolts and bearing the weight of the lower fastening guide rail. It can effectively prevent the connecting part 1 from deforming or breaking under force, and ensure the stability and safety of the solar panel fixing system.

[0031] like Figure 2 and Figure 3 As shown, the connecting part 1 is provided with a threaded hole 6 that is compatible with the bolt. The threaded hole 6 passes through the reinforcing protrusion 5. The reinforcing protrusion 5 itself can increase the strength of the connecting part 1. The threaded hole 6 passes through the reinforcing protrusion 5, so that the bolt can fully contact and cooperate with the reinforcing protrusion 5 when connected. When subjected to external force, the reinforcing protrusion 5 can better disperse the tension, making the connection between the bolt and the connecting part 1 more stable and effectively preventing the connecting part 1 from being torn or damaged due to excessive tension.

[0032] like Figure 2 and Figure 3 As shown, the cross-section of the reinforcing protrusion 5 is an inverted isosceles trapezoid. The inverted isosceles trapezoid cross-section can make the stress distribution more reasonable when under stress, avoid the concentration of stress in local areas, and make the stress distribution of the reinforcing protrusion 5 and the connecting part 1 more uniform.

[0033] like Figure 2 and Figure 3 As shown, the angle between the upper end of the fastening part 2 and the bottom of the connecting part 1 is 100° to 140°. Within this angle range, the fastening part 2 and the connecting part 1 can form a relatively ideal fastening state. Users can choose the appropriate angle according to actual needs, so that the fastening part can better fit the fastening guide rail. Specifically, the angle between the upper end of the fastening part 2 and the bottom of the connecting part 1 is 110°, which meets the requirements of the existing design.

[0034] like Figure 2 and Figure 3 As shown, the surface of the fastener is provided with an anti-corrosion layer. The anti-corrosion layer can isolate the fastener from the external corrosive media, forming a barrier to prevent oxygen, moisture and other substances from contacting the surface of the fastener, effectively slowing down or preventing the oxidation and corrosion process of the fastener, and maintaining the structural integrity of the fastener. The entire fastener is made of 6005-T5 aluminum alloy, and the surface is anodized to form an anti-corrosion layer.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
