Description

Technical Field

[0001] This application relates to the field of guide rail connection technology, and more specifically, to a card block for guide rail connection. Background Technology

[0002] Currently, there is a large demand for solar panel mounting systems in the market. While meeting basic requirements such as material environmental friendliness, strength, weight, and service life, it is also necessary to consider the convenience of installation and maintenance, so as to facilitate the replacement and disassembly of materials in the future and improve work efficiency.

[0003] Chinese patent CN209330005U discloses a guide rail connection module for solar panels, including a pressure block, a locking block, bolts, a solar panel, and a guide rail. The locking block is disposed within a guide groove of the guide rail, and the solar panel is disposed on the guide rail. The side edge of the pressure block is disposed on the side of the solar panel, and the pressure block and the locking block are connected by bolts. The module utilizes the locking block and the T-shaped slot's arc-shaped hook engagement, employing the principle of small infeed and large snap, to ensure a tight fit between the locking block and the T-shaped slot, increasing overall joint strength. The pressure block adds a side edge, firmly pressing the solar panel onto the guide rail, avoiding operational errors and damage to the product's appearance caused by drilling holes and screwing. The module is simple to operate, easy to install and disassemble, improves construction efficiency, and saves costs.

[0004] However, in the actual use of the aforementioned guide rail connection modules for solar energy systems, the stress distribution of the locking blocks exhibits significant drawbacks. Specifically, the main stress concentration points of the locking blocks are at their connection with the bolts and their connection with the guide rail grooves. When subjected to complex and variable outdoor loads such as wind and snow accumulation over extended periods, these two critical stress-bearing components bear extremely heavy loads, easily leading to overload damage and causing the solar panels to fall, injuring people and damaging property. This poses a significant safety hazard and severely compromises the long-term stable operation of the entire solar energy system. Summary of the Invention

[0005] The purpose of this application is to provide a locking block for rail connection, which can solve the technical problem that in the actual use of existing solar rail connection modules, the force of the locking block is concentrated at the connection with the bolt and the connection with the rail guide groove. When subjected to complex outdoor wind force, snow accumulation and other loads for a long time, the locking block is prone to overload damage, which will cause the solar panel to fall off. This poses a safety hazard of injury and property damage, and also greatly hinders the long-term stable operation of the solar system.

[0006] This application provides a locking block for connecting guide rails, including a first connecting part for connecting with bolts. The bottom of the first connecting part is integrally formed with a first reinforcing protrusion. The two sides of the first connecting part are integrally formed with symmetrically arranged second connecting parts. The lower part of the second connecting part is provided with an outward arc-shaped hook. The second connecting part is integrally formed with a second reinforcing protrusion at the starting position of the arc-shaped hook.

[0007] Furthermore, the first connecting part is provided with a threaded hole that is adapted to the bolt, and the threaded hole penetrates the first reinforcing protrusion.

[0008] Furthermore, the cross-section of the first reinforcing protrusion is an inverted isosceles trapezoid.

[0009] Furthermore, the connection between the second reinforcing protrusion and the second connecting portion forms an upward hook.

[0010] Furthermore, the first connecting portion, the first reinforcing protrusion, the second connecting portion, and the second reinforcing protrusion are all made of 6005-T5.

[0011] Furthermore, the surfaces of the first connecting portion, the first reinforcing protrusion, the second connecting portion, and the second reinforcing protrusion are all provided with an anti-corrosion layer.

[0012] The beneficial effects of this utility model are:

[0013] This utility model effectively increases the structural strength of the first connecting part by integrally forming a first reinforcing protrusion at the bottom of the first connecting part. When connected with bolts, it can better disperse the pressure brought by bolt tightening, prevent deformation or damage due to excessive local stress, and ensure the long-term reliability of the connection between the card block and the bolt.

[0014] This utility model strengthens the key stress-bearing area of ​​the arc hook by using a second reinforcing protrusion located at the starting position of the second connecting part. Since the arc hook is frequently subjected to stress changes during use, the second reinforcing protrusion can effectively alleviate stress concentration, improve the fatigue resistance of the block under repeated stress, and extend its service life.

[0015] This utility model improves the structural strength of the entire locking block and enhances its load-bearing capacity by setting the first and second reinforcing protrusions. This prevents the locking block from being overloaded and damaged by natural loads such as wind and snow accumulation, effectively eliminates the safety hazards of falling solar panels causing injury or damage, and ensures the long-term stable operation of the solar energy system.

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 1 and Figure 2As shown, this application provides a locking block for connecting guide rails, including a first connecting part 1 for connecting with bolts. The bottom of the first connecting part 1 is integrally formed with a first reinforcing protrusion 2. The reinforcing protrusion 2 can effectively increase the structural strength of the first connecting part 1, and can better distribute the pressure brought by bolt tightening when connected with bolts, preventing deformation or damage due to excessive local stress, and ensuring the long-term reliability of the connection between the locking block and the bolts. The two sides of the first connecting part 1 are integrally formed with symmetrically arranged second connecting parts 3. The lower part of the second connecting part 3 is provided with an outward arc-shaped hook 4, and the second connecting part 3 is located at the starting position of the arc-shaped hook 4. The one-piece molded design features a second reinforcing protrusion 5, which provides focused reinforcement to the critical stress-bearing area of ​​the arc-shaped hook 4. Since the arc-shaped hook 4 frequently experiences stress changes during use, the second reinforcing protrusion 5 effectively alleviates stress concentration, improves the fatigue resistance of the block under repeated stress, and extends its service life. By setting the first reinforcing protrusion 2 and the second reinforcing protrusion 5, the structural strength of the entire block is improved, the load-bearing capacity of the block is enhanced, and the block is prevented from being overloaded and damaged by natural loads such as wind and snow accumulation. This effectively eliminates the safety hazards of falling solar panels causing injury or damage, and ensures the long-term stable operation of the solar energy system.

[0029] like Figure 1 As shown, the first connecting part 1 is provided with a threaded hole 6 that matches the bolt. The threaded hole 6 passes through the first reinforcing protrusion 2, so that after the bolt is screwed in, the tension and pressure generated can be evenly distributed to a larger area of ​​the locking block by means of the first reinforcing protrusion 2. Compared with the ordinary threaded hole 6 design, this method can significantly reduce the local stress concentration phenomenon in the first connecting part 1 during the bolt tightening process, avoid material cracking or thread damage caused by excessive stress accumulation, thereby greatly improving the stability and reliability of the connection between the locking block and the bolt, and ensuring that the guide rail connection module remains stable during long-term use.

[0030] like Figure 1 and Figure 2 As shown, the cross-section of the first reinforcing protrusion 2 is an inverted isosceles trapezoid. When subjected to force, the hypotenuse of the isosceles trapezoid can decompose the pressure into horizontal and vertical components. The horizontal components can cancel each other out, reducing the lateral compression on the entire block. The vertical component is evenly distributed at the bottom of the protrusion, avoiding stress concentration at a certain point. This enhances the block's resistance to pressure in the vertical direction, making the connection between the block and the bolt more stable and less prone to deformation or damage due to long-term pressure. It effectively improves the structural strength and durability of the block and ensures the reliability of the guide rail connection.

[0031] like Figure 1 and Figure 2As shown, the connection between the second reinforcing protrusion 5 and the second connecting part 3 forms an upward hook. The hook reduces the angle between the second reinforcing protrusion 5 and the second connecting part 3, thereby enhancing the tensile strength of the connection between the second reinforcing protrusion 5 and the second connecting part 3.

[0032] like Figure 1 and Figure 2 As shown, the materials of the first connecting part 1, the first reinforcing protrusion 2, the second connecting part 3, and the second reinforcing protrusion 2 are all 6005-T5. 6005-T5 aluminum alloy has moderate tensile strength, which can reach about 260MPa. It can provide solid and reliable support for the key parts of the card block. Whether the first connecting part 1 bears the tightening tension of the bolts or the second connecting part 3 resists the impact of external forces in the guide rail connection, the strength characteristics of the material itself can ensure the stability of the card block structure and prevent damage such as breakage and deformation. This effectively ensures the stability of the guide rail connection.

[0033] like Figure 1 and Figure 2 As shown, the surfaces of the first connecting part 1, the first reinforcing protrusion 2, the second connecting part 3, and the second reinforcing protrusion 2 are all provided with anti-corrosion layers. The outdoor environment is complex and harsh, and the guide rail connecting block is constantly facing potential threats such as rainwater erosion and moisture corrosion. The anti-corrosion layer tightly isolates external corrosive factors from contact with the block material itself, greatly slowing down or even stopping the corrosion process, so that the material properties of each component of the block can be maintained for a long time, effectively avoiding problems such as structural weakening and strength reduction caused by corrosion, thereby significantly extending the service life of the block.

[0034] The guide rail connection block of this application is an improvement on the prior art. When in use, the block of this application replaces the block in the guide rail connection module for solar energy published by Chinese Patent No. CN209330005U.

[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.
