Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic guide rail splicing technology, and in particular to a guide rail splicing structure. Background Technology
[0002] Current photovoltaic (PV) support system designs are becoming increasingly diverse to accommodate roofs of different shapes, tilt angles, and materials. In practical applications, due to variations in roof dimensions, it is often necessary to splice guide rails of different lengths to meet installation requirements. Traditionally, shorter guide rail sections are spliced together using self-tapping screws or high-strength bolts to extend the overall length, such as... Figure 1 As shown. However, the sizes of the spliced guide rails are inconsistent, and over time, these fasteners often loosen due to environmental erosion, temperature changes, or mechanical stress, which not only affects the stability of the photovoltaic panels but may also reduce the power generation efficiency of the entire system.
[0003] To overcome this challenge, engineers proposed an innovative solution: designing two guide rails of the same diameter as a structure that can be fitted onto the ends of an auxiliary guide rail with a smaller diameter. The intention behind this design is to improve the stability of the joint by adding extra support points, reducing overall instability caused by loosening of a single fixing point, while ensuring that the guide rails at both ends are of the same diameter. Figure 2 As shown. However, even with this improved design, if traditional self-tapping screws or bolts are still used for fixing, the loosening problem may still reappear after long-term use, especially under extreme weather conditions, where the risk is more significant. Utility Model Content
[0004] The purpose of this invention is to propose a guide rail splicing structure that can solve the problem of loosening after splicing two sections of guide rail.

[0007] The upper end of the sleeved guide rail is provided with two guide rail latches, and a latching space is formed between the two guide rail latches;
[0008] The connecting guide rail has a through guide rail receiving groove, and the cross-section of the guide rail receiving groove is U-shaped.

[0011] The splicing fastener passes through the splicing center through hole and is inserted into the sleeved guide rail, and fixes the splicing body in the snap-fit space of the sleeved guide rail;
[0012] When the connecting guide rail is sleeved onto the sleeved guide rail from one end through the guide rail receiving groove, and moves forward along the length direction of the sleeved guide rail toward the middle section of the sleeved guide rail, the connecting guide rail contacts the splicing body and the splicing barb in sequence. The splicing barb is used to prevent the connected guide rail from moving in the opposite direction.
[0013] Preferably, guide rail guide grooves are formed on the outer walls of the left and right sides of the sleeved guide rail along its length.
[0014] The inner walls on both the left and right sides of the sleeve guide rail are respectively provided with guide rail guide blocks along its length.
[0015] The guide block matches the guide groove.
[0016] Preferably, splicing guide portions are provided on both sides of the splicing body along the length direction of the splicing body.
[0017] Preferably, the splicing guide is provided with a splicing stop at one end near the center of the splicing body.
[0018] Preferably, the end of the splicing guide near the center of the splicing body does not exceed the center of the splicing body.
[0019] Preferably, the splicing cut-off portion is arranged perpendicularly to the splicing guide portion, and the end of the splicing cut-off portion away from the splicing guide portion is located near the center of the splicing body.
[0020] Preferably, the side of the splicing guide is flush with the side of the splicing body.

[0025] 4. Extended service life: Sturdy connections and precise alignment help reduce wear and vibration of the guide rail system, thereby extending the service life of the entire system.
[0026] 5. Improve overall performance: By preventing reverse movement of the guide rail and providing precise positioning, this structure helps improve the overall operational stability and performance of the guide rail system. Attached Figure Description

[0039] A guide rail splicing structure includes a sleeved guide rail 100, two sleeved guide rails 200, and a splicing component 2 installed between the sleeved guide rail 100 and the sleeved guide rails 200.
[0040] The upper end of the sleeved guide rail 100 is provided with two guide rail latches 1001, and a latching space is formed between the two guide rail latches 1001.
[0041] The sleeve guide rail 200 has a through guide rail receiving groove 2001, and the cross section of the guide rail receiving groove 2001 is U-shaped.
[0042] The splicing assembly 2 includes a splicing body 21 and splicing fasteners 22;
[0043] The splicing body 21 has a splicing center through hole 210 at its center, and two splicing barbs 211 are provided on the splicing body 21, with the opening ends of the two splicing barbs 211 facing the splicing center through hole 210.
[0044] The splicing fastener 22 passes through the splicing center through hole 210 and is inserted into the sleeved guide rail 100, and fixes the splicing body 21 in the snap-fit space of the sleeved guide rail 100;
[0045] When the connecting guide rail 200 is connected to the connected guide rail 100 from one end through the guide rail receiving groove 2001, and moves forward along the length direction of the connected guide rail 100 toward the middle section of the connected guide rail 100, the connecting guide rail 200 contacts the splicing body 21 and the splicing barb 211 in sequence. The splicing barb 211 is used to prevent the connected guide rail from moving in the opposite direction.
[0046] like Figure 3-7 As shown, the working principle of this guide rail splicing structure is based on its unique structural design, aiming to achieve an efficient and stable connection between the sleeved guide rail 100 and the sleeved guide rail 200. First, the upper end of the sleeved guide rail 100 is provided with a snap-fit space formed by two guide rail latches 1001, which provides a reliable support point for subsequent splicing and fixing. The guide rail receiving groove 2001 of the sleeved guide rail 200 is designed with a concave cross-section. This cross-section design has a high performance utilization rate, which not only allows the sleeved guide rail 200 to fit tightly and stably on the sleeved guide rail 100, greatly enhancing its torsional and deformation resistance, but also provides sufficient operating space for the splicing component 2, and has a lower weight per meter, making it more cost-effective. Next, fasteners 22, such as rivets, are passed through the splicing center through-hole 210 of the splicing body 21 and securely inserted into the predetermined position (usually the middle section) of the guide rail 100 to be fitted, thereby fixing the splicing body 21 onto the guide rail 100. This step ensures a stable connection between the splicing body 21 and the guide rail 100, providing a solid foundation for subsequent fitting operations.
[0047] When the connecting guide rail 200 is sleeved onto the sleeved guide rail 100 from one end, and moves forward along the length of the sleeved guide rail 100 towards the middle section of the sleeved guide rail 100, i.e., the location of the splicing body 21, they gradually come into contact with the splicing body 21 and the splicing barbs 211 provided thereon. Because the two splicing barbs 211 have their open ends facing the splicing center through hole 210 and are arranged facing each other, they can engage with the inner wall of the sleeved guide rail 200 when the connecting guide rail 200 contacts, preventing them from retracting or being pulled out, thus forming a physical lock. This locking mechanism not only prevents the reverse movement of the connecting guide rail 200, but also ensures precise docking and a stable connection between one section of the sleeved guide rail 100 and the two sections of the connecting guide rail 200, thereby achieving the purpose of a rigid splicing guide rail.
[0048] In summary, the beneficial effects of this guide rail splicing structure are as follows:
[0049] 1. Improve connection stability: Through the dual action of splicing fasteners 22 and splicing barbs 211, this guide rail splicing structure can significantly improve the connection stability between guide rails and reduce the risk of failure caused by loosening or misalignment.
[0050] 2. Simplified installation process: The design of the splicing center through hole 210 and the splicing fastener 22 through-hole make the installation of the splicing body 21 simple and quick, reducing the installation difficulty and cost.
[0051] 3. High adaptability: This structure can be widely used in the splicing of guide rails of different specifications and materials, and has strong versatility and adaptability.
[0052] 4. Extended service life: Sturdy connections and precise alignment help reduce wear and vibration of the guide rail system, thereby extending the service life of the entire system.
[0053] 5. Improve overall performance: By preventing reverse movement of the guide rail and providing precise positioning, this structure helps improve the overall operational stability and performance of the guide rail system.
[0054] To further explain, the left and right outer walls of the sleeved guide rail 100 are respectively provided with guide rail guide grooves 1002 along their length direction;
[0055] The inner walls on the left and right sides of the sleeve guide rail 200 are respectively provided with guide rail guide blocks 2002 along its length direction;
[0056] The guide block 2002 is matched with the guide groove 1002.
[0057] like Figure 3 , 4 As shown in Figure 7, when the connecting guide rail 200 begins to connect with one end of the connecting guide rail 100, its internal guide rail guide block 2002 slides along the guide rail guide groove 1002 on the outer side of the connecting guide rail. This sliding not only provides a clear path and direction for the connection process but also ensures the stability and straightness of the connecting guide rail during movement. The tight fit between the guide rail guide block 2002 and the guide rail guide groove 1002 effectively prevents the connecting guide rail from shifting or shaking during movement, thereby ensuring the accuracy and reliability of the connection.
[0058] To further explain, splicing guides 212 protrude from both sides of the splicing body 21 along the length direction of the splicing body 21.
[0059] like Figure 5 and 6As shown, to ensure a smoother and more accurate splicing process, when the splicing guide rail 200 needs to be spliced with the spliced guide rail 100, they first approach the splicing body 21 along the direction of the guide rail guide block 2002 and the guide rail guide groove 1002. As the splicing guide rail 200 gradually approaches, it first contacts the splicing guide part 212 and moves smoothly to the center position of the splicing body 21 under its guidance. The design of the splicing guide part 212 provides a clear path and direction guide for the splicing guide rail 200, eliminating the need for excessive adjustments and corrections, and preventing misalignment between the splicing guide rail 200 and the splicing body 21.
[0060] To further explain, the splicing guide 212 is provided with a splicing stop 213 at one end near the center of the splicing body 21.
[0061] like Figure 5 , 6 As shown in Figure 7, when the two connecting rails 200 need to be connected to the connecting rail 100, they gradually approach the splicing body 21 along the direction of the splicing guide 212. The splicing guide 212 provides a smooth transition for the connecting rails 200, allowing them to easily align with the center of the splicing body 21. As the connecting rails 200 continue to advance, they encounter the splicing stop 213 located at the end of the splicing guide 212. The splicing stop 213 acts as a physical barrier, limiting further movement of the connecting rails 200 and preventing them from going too deep or deviating from the intended installation position. When the connecting rails 200 contact the splicing stop 213, they stop advancing and are positioned precisely at the center of the splicing body 21, firmly in contact with the splicing barbs 211, avoiding installation errors caused by excessive movement or deviation.
[0062] To further explain, the end of the splicing guide 212 near the center of the splicing body 21 does not exceed the center of the splicing body 21.
[0063] like Figure 5 , 6 As shown in Figure 7, in one embodiment of the optimized guide rail splicing structure, the splicing guide 212 is designed more precisely. One end of the guide 212, near the center of the splicing body 21, is explicitly positioned not to exceed the center of the splicing body 21. In the optimal case, the splicing stop 213, i.e., the end of the splicing guide 212, is perfectly aligned with the center of the splicing body 21. This design ensures that when the two end-mounted guide rails 200 move along the splicing guide 212 and contact the splicing stop 213, they can precisely align together, forming a seamless connection.
[0064] Specifically, as the connecting guide rails 200 smoothly advance along the splicing guide portion 212, they experience guiding force from the splicing guide portion 212, maintaining a straight and stable movement trajectory. When they reach the splicing stop portion 213, due to the alignment of the splicing stop portion 213 with the center of the splicing body 21, the connecting guide rails 200 can stop precisely at the optimal position for docking with the other connecting guide rail 200. At this time, through the combined action of the splicing fastener 22 and the splicing barb 211, the connecting guide rails 200 can be firmly fixed to the splicing body 21 and the connected guide rail 100, achieving seamless docking.
[0065] To further explain, the splicing cut-off portion 213 is arranged perpendicularly to the splicing guide portion 212, and the end of the splicing cut-off portion 213 away from the splicing guide portion 212 is located near the center of the splicing body 21.
[0066] like Figure 5 , 6 As shown in Figure 7, when the two connecting guide rails 200 need to be connected to the connecting guide rail 100, they gradually approach the splicing body 21 along the smooth surface of the splicing guide 212. The splicing guide 212 provides stable and clear guidance for the connecting guide rails 200, enabling them to move linearly and precisely. As the connecting guide rails 200 continue to advance, they encounter the vertical splicing stop 213 located at the end of the splicing guide 212.
[0067] Because the splicing stop part 213 is perpendicular to the splicing guide part 212, it effectively forms a blocking surface, preventing the socket guide rail 200 from moving further. At this time, the socket guide rail 200 is exactly located at the predetermined position at the center of the splicing body 21, or is in a ready state to dock with the socket guide rail 200 at the other end.
[0068] To further explain, the side of the splicing guide 212 is flush with the side of the splicing body 21.
[0069] like Figure 5 , 6 As shown in Figure 7, when the splicing body 2 is installed in the snap-fit space on the sleeve guide rail 100, the two side guide rail snap tongues will abut against the adjacent splicing guide part 212, further ensuring the stable connection between the splicing body 21 and the sleeve guide rail 100, providing a solid foundation for subsequent sleeve operations.
[0070] When the connecting guide rail 200 slides along the splicing guide 212, since the side of the splicing guide 212 is flush with the side of the splicing body 21, the connecting guide rail 200 can experience a smooth and continuous transition, making it easier to maintain a straight and stable movement trajectory. This design reduces friction, jamming, or misalignment caused by uneven sides, making the installation process smoother.
[0071] Meanwhile, the flush side design also helps to improve the overall strength and stability of the splicing structure. When subjected to external forces, the splicing body 21 and the splicing guide 212 can work together as a whole to bear the load, reducing the risk of damage caused by local stress concentration.
[0072] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
