Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket system universal for roofs. Background Art

[0002] The installation of rooftop photovoltaic modules has become an important practice in promoting green energy. However, the diversity of roof structures, such as ceramic tiles, asphalt tiles, metal tiles and other different types of roofs, has brought challenges to the installation of photovoltaic systems. Especially in large-scale photovoltaic projects, one project often covers multiple roof types, which undoubtedly increases the complexity of the installation work.

[0003] What is even more difficult is that the frame height of photovoltaic modules is not uniform. In order to ensure that photovoltaic modules can be stably fixed on the rails, it is necessary to match pressure codes of different specifications. The photovoltaic support systems currently on the market often design different rails and bases according to different roof types, and the splicing between the rails is mostly connected by self-tapping screws or bolts. For module frames of different heights, different specifications of side pressure codes or medium pressure codes are required. Although this design meets the installation requirements to a certain extent, it brings problems such as a wide variety of materials, easy confusion during on-site installation, and low splicing construction efficiency.

[0004] In addition, materials of various specifications also mean higher storage costs. Enterprises need to allocate storage space for each specification of materials, which not only increases the difficulty of warehouse management, but also reduces the turnover efficiency of materials. In the context of the rapid development of the photovoltaic industry, this inefficient material management method is obviously unable to meet the needs of the market.

[0005] Therefore, it is particularly important to develop a universal photovoltaic support system for roofs. Summary of the invention

[0006] The purpose of the present invention is to provide a universal photovoltaic support system for rooftops, which can not only greatly simplify the installation process of the photovoltaic system and improve the construction efficiency, but also reduce the material storage cost and improve the material turnover efficiency. This is of great significance for promoting the widespread application and development of rooftop photovoltaic systems.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] A universal photovoltaic support system for roofs, comprising a spliced ​​rail, a rail to be installed, a connected rail, a cross assembly, a splicing assembly, a coding assembly, a supporting assembly, an installation assembly, a connecting assembly, a clamping assembly and a fixing assembly;

[0009] The guide rail to be installed is sleeved on the periphery of the guide rail to be spliced, the splicing assembly is installed at the overlapping portion of the guide rail to be spliced ​​and the guide rail to be installed, and the splicing assembly is used to fix and splice the guide rail to be spliced ​​and the guide rail to be installed to form a spliced ​​and lengthened guide rail;

[0010] The connected guide rail is installed above the guide rail to be installed, the cross assembly is installed at the intersection of the guide rail to be installed and the connected guide rail, and the cross assembly is used to cross-connect the guide rail to be installed and the connected guide rail to form a cross fixed guide rail;

[0011] The code pressing component is installed above the guide rail to be installed, and the code pressing component and a part of the guide rail surface at the upper end of the guide rail to be installed form a code pressing cavity with different heights, and the code pressing cavity is used to place the photovoltaic module;

[0012] One end of the mounting assembly is provided with a mounting opening with adjustable size, and the mounting opening is used to install the guide rail to be installed;

[0013] The other end of the mounting assembly is fixedly connected to one end of the supporting assembly, one end of the clamping assembly and one end of the fixing assembly through the connecting assembly, respectively; the other end of the supporting assembly is mounted on an external ceramic tile roof, the other end of the clamping assembly is mounted on an external metal tile roof, and the other end of the fixing assembly is mounted on an external asphalt tile roof.

[0014] One of the above technical solutions has the following beneficial effects: 1. High flexibility: Through splicing components and cross components, the system can flexibly adjust the length and angle of the guide rail to adapt to roof structures of different shapes and sizes, and improve the installation efficiency and stability of photovoltaic modules. 2. Wide applicability: The design of the support component, clamping component and fixing component enables the system to be widely applicable to various types of roofs such as ceramic tiles, metal tiles and asphalt tiles, meeting the installation requirements in different scenarios. 3. Simplified installation process: The design of the installation component and the code pressing component simplifies the installation process of the guide rail and photovoltaic modules. Through the adjustable size installation port and the code pressing cavity, users can easily fix the guide rail and photovoltaic modules in the predetermined position to improve the installation efficiency. 4. Reduce costs: Modular design and flexible connection reduce the types and quantities of materials, reduce storage costs and material management difficulties, and improve the turnover efficiency of materials. 5. Improve safety: Through the design of cross-fixed guide rails and multiple fixing components, the system can ensure the stability and safety of photovoltaic modules under severe weather conditions and extend the service life of the photovoltaic system.

[0039] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] A universal photovoltaic support system for roofs, comprising a spliced ​​rail 100, a rail to be installed 200, a connected rail 300, a cross assembly 1, a splicing assembly 2, a coding assembly 3, a support assembly 4, an installation assembly 5, a connection assembly 6, a clamping assembly 7 and a fixing assembly 8;

[0041] The guide rail 200 to be installed is sleeved on the periphery of the spliced ​​guide rail 100, and the splicing assembly 2 is installed at the overlap of the spliced ​​guide rail 100 and the guide rail 200 to be installed. The splicing assembly 2 is used to fix and splice the spliced ​​guide rail 100 and the guide rail 200 to be installed to form a spliced ​​and lengthened guide rail;

[0042] The connected guide rail 300 is installed above the guide rail 200 to be installed, and the cross assembly 1 is installed at the intersection of the guide rail 200 to be installed and the connected guide rail 300. The cross assembly 1 is used to cross-connect the guide rail 200 to be installed and the connected guide rail 300 to form a cross fixed guide rail;

[0043] The code pressing component 3 is installed above the guide rail 200 to be installed, and the code pressing component 3 and a part of the guide rail surface at the upper end of the guide rail 200 to be installed form a code pressing cavity 30 with different heights, and the code pressing cavity 30 is used to place the photovoltaic module;

[0044] One end of the mounting assembly 5 is provided with a mounting opening 50 of adjustable size, and the mounting opening 50 is used to install the guide rail 200 to be installed;

[0045] The other end of the mounting component 5 is fixedly connected to one end of the supporting component 4, one end of the clamping component 7 and one end of the fixing component 8 through the connecting component 6, the other end of the supporting component is installed on an external ceramic tile roof, the other end of the clamping component 7 is installed on an external metal tile roof, and the other end of the fixing component 8 is installed on an external asphalt tile roof.

[0046] like Figure 1-24 As shown, the present invention is a universal photovoltaic support system for roofs, and its working principle is mainly based on modular design and flexible connection:

[0047] When it is necessary to install a spliced ​​extended guide rail: the guide rail 200 to be installed is sleeved on the periphery of the spliced ​​guide rail 100, and the two are fixedly spliced ​​by the splicing component 2 to form a spliced ​​extended guide rail. This step allows the user to flexibly adjust the length of the guide rail according to the actual length requirements of the roof. When it is necessary to install a cross-fixed guide rail: the guide rail 200 to be installed is installed above the connected guide rail 300, and the connection is achieved at the intersection of the two by the cross component 1 to form a cross-fixed guide rail. This design allows the guide rail to be fixed at multiple angles and directions on a complex roof structure, thereby improving the installation flexibility and stability of the photovoltaic module. When it is necessary to install a photovoltaic module: the compression code component 3 is installed above the guide rail 200 to be installed, and it forms a compression code placement cavity 30 of different heights with the partial guide surface at the upper end of the guide rail 200 to be installed for placing photovoltaic modules. This step allows the user to flexibly adjust the installation adaptability of the compression code component 3 according to the actual needs of the photovoltaic module. Next, the installation component 5 and the connection component 6 can be used flexibly with the support component 4, the clamping component 7 and the fixing component 8 in different ways: one end of the installation component 5 is provided with an adjustable installation opening 50 for installing the guide rail 200 to be installed. The other end is fixedly connected to the support component 4, the clamping component 7 and the fixing component 8 through the connection component 6. These components are respectively applicable to different types of roofs, such as ceramic tile roofs, metal tile roofs and asphalt tile roofs, ensuring that the photovoltaic support system can be widely applicable to various roof structures.

[0048] In summary, the beneficial effects of the present invention are as follows:

[0049] 1. High flexibility: Through the splicing component 2 and the cross component 1, the system can flexibly adjust the length and angle of the guide rail to adapt to roof structures of different shapes and sizes, and improve the installation efficiency and stability of the photovoltaic module. 2. Wide applicability: The design of the support component 4, the clamping component 7 and the fixing component 8 enables the system to be widely applicable to various types of roofs such as ceramic tiles, metal tiles and asphalt tiles, meeting the installation requirements in different scenarios. 3. Simplified installation process: The design of the installation component 5 and the code pressing component 3 simplifies the installation process of the guide rail and the photovoltaic module. Through the adjustable size installation port 50 and the code pressing cavity 30, the user can easily fix the guide rail and the photovoltaic module in the predetermined position to improve the installation efficiency. 4. Reduce costs: Modular design and flexible connection reduce the types and quantities of materials, reduce storage costs and material management difficulties, and improve the turnover efficiency of materials. 5. Improve safety: Through the design of cross-fixed guide rails and multiple fixing components, the system can ensure the stability and safety of photovoltaic modules under severe weather conditions and extend the service life of the photovoltaic system.

[0050] Further explanation, the guide rail 200 to be installed and the guide rail 300 to be connected have the same structure, the cross section of the guide rail 200 to be installed is concave, two first guide rail clamping parts 2003 are provided at the upper end notch of the guide rail 200 to be installed, the first guide rail clamping parts 2003 are arranged opposite to each other and are not connected, and the upper end notch of the guide rail 200 to be installed and the two first guide rail clamping parts 2003 form a clamping groove;

[0051] The cross assembly 1 includes a first cross connector 11, a second cross connector 12, a cross adjustment member 13 and a cross fastener 14;

[0052] The first cross-connecting member 11 comprises a cross-abutting portion 111 and a cross-placing portion 112, a placement space is formed between one end of the cross-placing portion 112 away from the cross-abutting portion 111 and the cross-placing portion 111, and a first cross-positioning portion 113 is protruded from the bottom of the cross-placing portion, and a cross-adjusting strip hole 115 is opened between the cross-abutting portion 111 and the cross-placing portion 112.

[0053] The first cross-connecting member 11 is clamped to the guide rail 200 to be installed through the first cross-positioning portion 113 and the clamping groove, the lower end of the second cross-connecting member 12 is penetrated by the cross-adjusting bar hole 115, and one end of the second cross-connecting member 12 is clamped to the clamping groove;

[0054] The cross adjustment member 13 is installed at the upper end of the second cross connection member 12, and one end of the cross adjustment member 13 close to the cross abutment portion 111 abuts against the cross abutment portion 111, and the connected guide rail 300 is placed in the placement space, and the guide rail 200 to be installed and the connected guide rail 300 are placed vertically;

[0055] The second cross-connecting member 12 includes a cross vertical abutting surface 131. The second cross-connecting member 12 and the cross-adjusting member 13 can move along the extending direction of the cross-adjusting strip hole 115. The movement is used to adjust the size of the placement space so that the cross vertical abutting surface 131 of the cross-adjusting member 13 abuts against the connected guide rail 300.

[0056] The cross adjustment member 13 and the second cross connection member 12 are fixedly installed by the cross fastener 14 .

[0057] like Figure 2-6 As shown, the working principle of the cross assembly 1 is mainly based on four core steps: snap-in, positioning, adjustment and tightening:

[0058] First, align the first cross positioning portion 113 of the first cross connector 11 and snap it into the snap groove of the guide rail 200 to be installed. This snap groove is formed by the notch at the upper end and two first guide rail snap parts 2003 facing each other but not connected, ensuring a stable connection between the first cross connector 11 and the guide rail 200. Subsequently, pass the lower end of the second cross connector 12 through the cross adjustment bar hole 115 of the first cross connector 11, and snap one end through it into the snap groove of the same guide rail 200 to be installed, further enhancing the stability and reliability of the cross assembly. Then install the cross adjustment member 13 on the upper end of the second cross connector 12, and the end close to the cross adjustment member 13 abuts against the cross abutment portion 111.

[0059] Next, the connected guide rail 300 is placed vertically on the cross-placement portion 112 of the first cross-connector 11. At this time, the placement space formed by the cross-placement portion 112 and the cross-abutment portion 111 is sufficient, and the connected guide rail 300 can move freely in the placement space. Then, the second cross-connector 12 and the cross-adjustment member 13 are moved along the extension direction of the cross-adjustment bar hole 115 for adjustment, so that the cross vertical abutment surface 131 on the cross-adjustment member 13 is tightly abutted with the vertically placed connected guide rail 300. At this time, the cross-adjustment member 13 and the second cross-connector 12 are located at the optimal abutment position, and the connected guide rail 300 cannot move. It should be noted that during the adjustment process, one end of the cross-adjustment member 13 always abuts against the cross-abutment portion 111. This adjustment step applies pressure to the connected guide rail 300 through the cross-adjustment member 13 to ensure that it is stable and does not shake.

[0060] Finally, the cross-adjusting member 13 and the second cross-connecting member 12 are fixedly installed at the optimal abutment position using the cross-fastening member 14, thereby completing the cross-connection installation process of the guide rail structure.

[0061] It should be noted that the placement sequence of the second cross-connecting member 12, the cross-adjusting member 13, the cross-fastening member 14 and the connected guide rail 300 can be adjusted according to actual needs, and the above embodiment only provides the optimal placement and installation steps.

[0062] In summary, the present invention firstly utilizes the clamping structure to realize the fastening and installation of the first cross-connector 11 and the second cross-connector 12 on one of the guide rails, and then the second cross-connector 12 and the cross-adjusting member 13 placed thereon move on the first cross-connector 11 to clamp the second guide rail clamping portion 2004 of the other guide rail 200 and the second cross-positioning portion 114 on the first cross-connector 11, so that the cross-connection of the two guide rails 200 is completed, and the adjustment operation is more convenient. Then, the second cross-connector 12 and the cross-adjusting member 13 are fastened at the current position by the cross-fastening member 14, so that the connection of the two guide rails 200 is more stable, and the practicality is improved.

[0063] Therefore, the cross assembly 1 of the present invention has the following beneficial effects:

[0064] 1. Simplify the installation process: The design of snap-on and adjustment makes the installation process more intuitive and simple, reducing the requirements for the professional skills of the installers. 2. Improve the stability of the connection: The clamping effect of the multiple snap-on structures and the cross-adjustment members 13 ensures the stability and reliability of the connection between the guide rails 200, and reduces the risk of failure caused by loose connections. 3. Enhance adaptability: The design of the cross-adjustment bar holes 115 allows fine-tuning during the installation process to adapt to guide rails 200 of different sizes or installation conditions, improving the versatility and flexibility of the installation structure. 4. Easy maintenance: When the guide rail 200 needs to be repaired or replaced, just loosen the cross fasteners 14 to easily disassemble the entire cross assembly, reducing maintenance costs and time. 5. Improve overall performance: The stable connection and precise positioning ensure the stability and accuracy of the guide rail structure during operation, improving the overall performance and efficiency of the photovoltaic system.

[0065] To further explain, the cross-placement portion 112 is provided with a second cross-positioning portion 114 protruding from the top of one end away from the cross-abutment portion 111; the lower ends of the left and right side walls of the guide rail 200 to be installed and the connected guide rail 300 are both extended outward to provide a second guide rail clamping portion 2004; the second guide rail clamping portion 2004 arranged on the connected guide rail 300 near the second cross-positioning portion 114 is clamped with the second cross-positioning portion 114.

[0066] like Figure 4-6 As shown, when the connected guide rail 300 is vertically placed on the cross placement portion 112 of the first cross connector 11, the second guide rail clamping portion 2004 at the lower end of the right side wall of the connected guide rail 300 is clamped with the second cross positioning portion 114 on the first cross connector 11, thereby realizing the preliminary positioning and connection of the guide rail 200 to be installed and the connected guide rail 300 in the vertical direction, so that the guide rail 200 to be installed and the connected guide rail 300 can be stabilized during the subsequent adjustment of the cross adjustment member 13.

[0067] To further explain, the cross abutment portion 111 includes a cross inclined abutment plate 1111 , and the cross inclined abutment plate 1111 has an inclined abutment surface, and the inclined abutment surface is used for abutment of one end of the cross adjustment member 13 .

[0068] like Figure 4-6 As shown, in a preferred embodiment, the cross-abutment portion 111 of the first cross-connector 11 includes a cross-inclined abutment plate 1111, and this design further enhances the convenience of adjusting the cross-adjustment member 13. Specifically, when the cross-adjustment member 13 is installed at the upper end of the second cross-connector 12. At this time, one end of the cross-adjustment member 13 will abut against the cross-inclined abutment plate 1111 of the first cross-connector. The design of the cross-inclined abutment plate 1111 allows the cross-adjustment member 13 to gradually move along the inclination of the cross-inclined abutment plate 1111, thereby gradually adjusting the pressure distribution on the connected guide rail 300 during the movement, making the adjustment force more uniform and reducing stress concentration.

[0069] To further explain, the cross-abutment portion 111 also includes a cross-inclined support plate 1112 and a cross-horizontal support plate 1113, the upper end of the cross-inclined support plate 1112 is fixedly connected to the cross-inclined abutment plate 1111, and the lower end of the cross-inclined support plate 1112 is fixedly connected to one end of the cross-horizontal support plate 1113.

[0070] like Figure 4-6 As shown, after further refining the design of the first cross connector 11, the cross abutment portion 111 of the first cross connector 11 is designed as a stable triangular support structure, which is composed of a cross inclined support plate 1112, a cross inclined abutment plate 1111 and a cross horizontal support plate 1113. This design not only enhances the stability of the cross abutment portion, but also optimizes the interaction with the cross adjustment member 13. The specific working principle is as follows:

[0071] The cross-inclined support plate 1112 serves as a side of the triangular support structure, and its upper end is fixedly connected to the cross-inclined abutment plate 1111, and its lower end is fixedly connected to one end of the cross-horizontal support plate 1113. This design forms a stable triangular structure that can provide stable support force in all directions. When the cross-adjusting member 13 is installed on the upper end of the second cross-connecting member 12 and moves along the cross-adjusting bar hole 115 to contact the cross-abutment portion 111, one end of the cross-adjusting member first abuts against the cross-inclined abutment plate 1111. The design of the cross-inclined abutment plate 1111 allows the cross-adjusting member to gradually adapt to and fit the cross-abutment portion during the pressing process, achieving a smoother transition.

[0072] As the cross adjustment member 13 is further compressed, the cross inclined abutment plate 1111 transfers the pressure to the cross inclined support plate 1112, and then disperses it to the cross horizontal support plate 1113. The stability of the triangular support structure ensures that these pressures can be evenly distributed over the entire cross abutment portion, reducing stress concentration and local wear. By precisely moving the second cross connector 12 and the cross adjustment member 13 along the extension direction of the cross adjustment bar hole 115, precise adjustment and compression of the linked guide rails 300 can be achieved. Once the desired tightness is achieved, the cross adjustment member 13 and the second cross connector 12 are fixedly installed using the cross fastener 14 to ensure the stability and long-term reliability of the entire cross-connected guide rail structure.

[0073] To further illustrate, the second cross-connection member 12 includes a cross-connection fixing portion 121; cross-connection clamping portions 122 are respectively extended from both sides of the lower end of the cross-connection fixing portion 121, and the cross-connection clamping portions 122 are clamped with the clamping groove. Figure 2-3 As shown, after further refinement of the design of the second cross-connector 12, the second cross-connector 12 includes a cross-connection fixing portion 121 and cross-connection clamping portions 122 extending from both sides of the lower end of the fixing portion. This design enables the second cross-connector to be more firmly clamped with the clamping groove of the guide rail, thereby enhancing the stability and reliability of the entire cross-connection assembly. The specific working principle is as follows:

[0074] The cross-connection fixing portion 121 is the main part of the second cross-connection member 12, responsible for bearing and transmitting the pressing force from the cross-adjusting member 13. At the same time, it also provides a stable support foundation for the cross-connection clamping portion 122. The cross-connection clamping portion 122 extends from both sides of the lower end of the cross-connection fixing portion 121, and its shape and size match the clamping groove of the guide rail. During the installation process, the cross-connection clamping portion 122 is inserted and clamped in the clamping groove to form a stable mechanical connection.

[0075] To further explain, the cross-connection clamping portion 122 includes a cross-connection clamping hook 123 , and the cross-connection clamping hook 123 is disposed to protrude outwardly along the extension direction of the cross-connection clamping portion 122 .

[0076] like Figure 4-6 As shown, after describing in detail the design of the cross-connection clamping portion of the second cross-connector 12, its working principle can be further understood. The cross-connection clamping portion 122 includes a cross-connection clamping hook 123, which is protruded outwardly along the extension direction of the cross-connection clamping portion 122. This design enables the cross-connection clamping portion 122 to be more effectively clamped with the clamping groove of the guide rail 200 to be installed, thereby enhancing the stability and reliability of the connection.

[0077] First, the cross-connection hooks 123 are key components on the cross-connection card portion 122. They protrude outward to form an "inverted" effect. When the cross-connection card portion 122 is inserted into the engaging groove, as the cross-connection card portion 122 goes deeper, the cross-connection hooks 123 gradually unfold and contact the side walls of the engaging groove, and finally are completely engaged together. These cross-connection hooks 123 can fit tightly on the side walls of the engaging groove to form a mechanical lock. More importantly, due to the protruding design of the cross-connection hooks 123, they can provide additional resistance when subjected to external forces, preventing the cross-connection card portion 122 from accidentally falling out of the engaging groove. This design significantly improves the stability and reliability of the connection.

[0078] To further explain, a cross-resistance increasing pattern 124 is disposed inside the cross-connection clamping portion 122 .

[0079] like Figure 4-6 As shown, specifically, the cross resistance increasing lines 124 are a series of uneven textures or grooves engraved or pressed inside the cross connection clamp 122. These cross resistance increasing lines 124 can generate additional friction when in contact with the cross fastener 14, preventing the cross fastener 14 from sliding or disengaging when subjected to external force, thereby further enhancing the stability and reliability of the connection.

[0080] To further illustrate, the cross adjustment member 13 is an L-shaped member;

[0081] One end of the L-shaped member is provided with a cross-tilt adjustment surface 132, and the cross-tilt adjustment surface 132 cooperates and abuts with the cross-tilt abutment plate 1111 of the cross abutment portion 111, and the other end of the L-shaped member abuts against the upper end of the second guide rail clamping portion 2004 of the connected guide rail 300.

[0082] like Figure 4-6As shown, in a preferred embodiment, the cross adjustment member 13 is designed as an L-shaped member. This shape not only makes the installation process more intuitive and simple, reduces the requirements for the professional skills of the installer, but also enables it to provide support and adjustment functions in both horizontal and vertical directions. It is known that one end of the L-shaped member is provided with a cross-tilt adjustment surface 132, which is used to cooperate with the cross-tilt abutment plate 1111 of the cross abutment portion 111; the other end directly abuts against the upper end of the second guide rail clamping portion 2004 of the connected guide rail 300. During the adjustment process, the cross-tilt adjustment surface 132 fits tightly with the cross-tilt abutment plate 1111, and the relative position between the two is adjusted by moving the cross adjustment member 13. Since both surfaces are inclined, the pressure distribution on the vertical guide rail can be gradually changed during the movement, achieving a smoother and more uniform adjustment effect. The other end of the L-shaped member directly abuts against the upper end of the second rail clamping portion 2004 of the connected rail 300, and the cross adjustment member 13 is used to ensure a stable connection between the connected rail 300 and the first cross connection member 11. This design allows the cross adjustment member 13 to not only adjust the degree of compression, but also directly participate in the stability of the rail structure.

[0083] Further explanation, the horizontal surface of the L-shaped member is provided with a first cross-connection through hole 133, the vertical surface of the L-shaped member is the cross vertical abutment surface 131, and the cross vertical abutment surface 131 abuts against the connected guide rail 300; the cross-connection fixing portion 121 is provided with a second cross-connection through hole 1210; the cross fastener 14 is sequentially penetrated through the first cross-connection through hole 133 and the second cross-connection through hole 1210 to fix the cross adjustment member 13 and the second cross connection member 12 in place.

[0084] As is known, the L-shaped cross adjustment member 13 has a horizontal surface and a vertical surface. The horizontal surface is provided with a first cross connection through hole 133 for cooperating with the cross fastener 14. The cross connection fixing portion 121 is known to be the main body of the second cross connection member 12, on which a second cross connection through hole 1210 corresponding to the first cross connection through hole 133 on the L-shaped cross adjustment member is provided, for receiving the cross fastener 14 to achieve fixed installation.

[0085] like Figure 4-6As shown, the cross fastener 14 can be a cross fastener such as a bolt or a screw, and its length and diameter need to be selected according to actual needs to ensure a stable connection. During installation, the cross fastener 14 passes through the first cross connection through hole 133 on the L-shaped cross adjustment member and the second cross connection through hole 1210 on the second cross connection member 12 in sequence. Then, by rotating the head of the cross fastener 14 such as a nut, a nut, etc., it is tightened, so that the L-shaped cross adjustment member 13 and the second cross connection member 12 are tightly fixed together. When the cross fastener 14 is tightened, the vertical surface of the L-shaped cross adjustment member 13, as a cross vertical abutment surface 131, will firmly abut on the connected guide rail 300, providing direct support and clamping force. Not only the stability and reliability of the connected guide rail 300 are ensured, but also the loosening or displacement of the cross adjustment member 13 is prevented by the tightening force of the cross fastener 14.

[0086] To further illustrate, two guide rail latches 1001 are provided at the upper end of the spliced ​​guide rail 100, and a latching space is formed between the two guide rail latches 1001;

[0087] The guide rail 200 to be installed is provided with a penetrating guide rail receiving groove 2001, and the cross section of the guide rail receiving groove 2001 is formed in a concave shape;

[0088] The splicing assembly 2 includes a splicing body 21 and a splicing fastener 22;

[0089] A central through hole 210 is formed at the center of the splicing body 21. Two splicing barbs 211 are disposed opposite to each other on the splicing body 21, and the opening ends of the two splicing barbs 211 face the central through hole 210.

[0090] The splicing fastener 22 passes through the splicing center through hole 210 and penetrates the spliced ​​guide rail 100, and fixes the splicing body 21 in the clamping space of the spliced ​​guide rail 100;

[0091] When the guide rail 200 to be installed is sleeved on the guide rail 100 to be spliced ​​from one end of the guide rail 100 through the guide rail accommodating groove 2001, and moves forward along the length direction of the guide rail 100 to be spliced ​​toward the middle section of the guide rail 100 to be spliced, the guide rail 200 to be installed contacts the splicing body 21 and the splicing barb 211 in turn, and the splicing barb 211 is used to prevent the sleeved guide rail from moving in the reverse direction.

[0092] like Figure 7-8As shown, the working principle of the present guide rail splicing structure is based on its unique structural design, which aims to achieve an efficient and stable connection between the spliced ​​guide rail 100 and the guide rail 200 to be installed. First, the upper end of the spliced ​​guide rail 100 is provided with a clamping space formed by two guide rail latches 1001, which provides a reliable support point for subsequent splicing and fixation. The guide rail receiving groove 2001 of the guide rail 200 to be installed is designed as a concave cross-section. This cross-section design has a high performance utilization rate. Not only can the guide rail 200 to be installed be tightly and stably mounted on the spliced ​​guide rail 100, which greatly enhances the torsion and deformation resistance, but the guide rail receiving groove 2001 also provides sufficient operating space for the splicing assembly 2, and the weight per meter is lower, and the cost is more advantageous. Next, the splicing fastener 22, such as a rivet, passes through the splicing center through hole 210 of the splicing body 21 and is firmly inserted into a predetermined position, usually the middle section, of the spliced ​​guide rail 100, thereby fixing the splicing body 21 to the spliced ​​guide rail 100. This step ensures a stable connection between the splicing body 21 and the spliced ​​guide rail 100, providing a solid foundation for the subsequent sleeve operation.

[0093] When the guide rail 200 to be installed that needs to be connected is sleeved on the guide rail 100 to be spliced ​​from one end of the guide rail 100 to be spliced, and moves forward along the length direction of the guide rail 100 to the middle section of the guide rail 100 to be spliced, that is, the position of the splicing body 21, they will gradually contact the splicing body 21 and the splicing barbs 211 arranged thereon. Since the two splicing barbs 211 have their open ends facing the splicing center through hole 210 and are arranged opposite to each other, they can engage with the inner wall of the guide rail 200 to be installed when in contact with the guide rail 200 to be installed and cannot be withdrawn, forming a physical lock. This locking mechanism not only prevents the reverse movement of the guide rail 200 to be installed, but also ensures the precise docking and stable connection between a section of the spliced ​​guide rail 100 and two sections of the guide rails 200 to be installed, thereby achieving the purpose of rigid splicing of the guide rails.

[0094] In summary, the splicing assembly 2 of the present invention has the following beneficial effects:

[0095] 1. Improve the stability of the connection: Through the dual effects of the splicing fasteners 22 and the splicing barbs 211, the guide rail splicing structure can significantly improve the stability of the connection between the guide rails and reduce the risk of failure due to looseness or misalignment. 2. Simplify the installation process: The splicing center through hole 210 design and the splicing fastener 22 threading method make the installation of the splicing body 21 simple and quick, reducing the installation difficulty and cost. 3. Strong adaptability: This structure can be widely used in the splicing of guide rails of different specifications and materials, and has strong versatility and adaptability. 4. Extend the service life: Stable connection and precise docking help reduce wear and vibration of the guide rail system, thereby extending the service life of the entire system. 5. Improve overall performance: By preventing the reverse movement of the guide rail and precise limiting, this structure helps to improve the overall operating stability and performance of the guide rail system.

[0096] To further explain, the left and right outer walls of the spliced ​​guide rail 100 are respectively provided with guide rail guide grooves 1002 along their length directions; the left and right inner walls of the guide rail 200 to be installed are respectively provided with guide rail guide blocks 2002 along their length directions; the guide rail guide blocks 2002 match the guide rail guide grooves 1002.

[0097] like Figure 2-3 As shown in Figures 7-8, when the guide rail 200 to be installed starts to be inserted from one end of the guide rail 100 to be spliced, the guide rail guide block 2002 inside it will slide along the guide rail guide groove 1002 on the outside of the spliced ​​guide rail. This sliding not only provides a clear path and direction guidance for the insertion process, but also ensures the stability and linearity of the guide rail to be installed during the movement. The close fit between the guide rail guide block 2002 and the guide rail guide groove 1002 effectively prevents the guide rail to be installed from deflecting or shaking during the movement, thereby ensuring the accuracy and reliability of the splicing.

[0098] To further explain, two sides of the splicing body 21 are provided with splicing guide portions 212 protruding along the length direction of the splicing body 21 .

[0099] like Figure 7-8 As shown, in order to make the sleeve connection process smoother and more accurate, when the guide rail 200 to be installed needs to be connected with the guide rail 100 to be connected, they will first approach the connection body 21 along the direction of the guide rail guide block 2002 and the guide rail guide groove 1002. As the guide rail 200 to be installed gradually approaches, the guide rail 200 to be installed will first contact the connection guide part 212, and move smoothly to the center of the connection body 21 under its guidance. The design of the connection guide part 212 provides a clear path and direction guide for the guide rail 200 to be installed, without excessive adjustment and correction, and also prevents the misalignment of the guide rail 200 to be installed and the connection body 21.

[0100] To further explain, a splicing stop portion 213 is disposed at one end of the splicing guide portion 212 close to the center of the splicing body 21 .

[0101] like Figure 2-3 As shown in Figures 7-8, when two sections of guide rails 200 to be installed need to be connected to the guide rails 100 to be spliced, they gradually approach the splicing body 21 along the direction of the splicing guide portion 212. The splicing guide portion 212 provides a smooth transition for the guide rails 200 to be installed, so that they can easily align with the center position of the splicing body 21. As the guide rails 200 to be installed continue to advance, they will encounter a splicing cut-off portion 213 set at the end of the splicing guide portion 212. The splicing cut-off portion 213 acts as a physical barrier to limit the further movement of the guide rails 200 to be installed, preventing them from going too deep or deviating from the predetermined installation position. When the guide rails 200 to be installed contact the splicing cut-off portion 213, they will stop moving forward and are exactly located at the center position of the splicing body 21 and in a position that is firmly in contact with the splicing barb 211, avoiding installation errors caused by excessive movement or deviation.

[0102] To further explain, one end of the splicing guide portion 212 close to the center of the splicing body 21 does not exceed the center of the splicing body 21 .

[0103] like Figure 2-3 As shown in FIGS. 7-8 , in one embodiment of the optimized guide rail splicing structure, the design of the splicing guide portion 212 is more sophisticated, and its end close to the center of the splicing body 21 is clearly set to not exceed the center of the splicing body 21, and in the best case, the splicing cut-off portion 213, i.e., the end of the splicing guide portion 212, is completely aligned with the center of the splicing body 21. Such a design ensures that when the guide rails 200 to be installed at both ends move along the splicing guide portion 212 and contact the splicing cut-off portion 213, they can be accurately docked together to form a seamless connection.

[0104] Specifically, when the guide rails 200 to be installed are smoothly pushed along the splicing guide part 212, they will feel the guiding force from the splicing guide part 212, so that they maintain a straight and stable moving track. When reaching the splicing cut-off part 213, due to the alignment of the splicing cut-off part 213 with the center of the splicing body 21, the guide rails 200 to be installed can just stay in the best position to dock with the other end of the guide rails 200 to be installed. At this time, through the joint action of the splicing fastener 22 and the splicing barb 211, the guide rails 200 to be installed can be firmly fixed on the splicing body 21 and the spliced ​​guide rails 100, achieving seamless docking.

[0105] To further explain, the splicing cut-off portion 213 is disposed perpendicularly to the splicing guide portion 212 , and one end of the splicing cut-off portion 213 away from the splicing guide portion 212 is disposed close to the center of the splicing body 21 .

[0106] like Figure 2-3 As shown in Figures 7-8, when two sections of guide rails 200 to be installed need to be connected to the guide rails 100 to be spliced, they gradually approach the splicing body 21 along the smooth surface of the splicing guide 212. The splicing guide 212 provides a stable and clear guide for the guide rails 200 to be installed, so that they can move straight and accurately. As the guide rails 200 to be installed continue to advance, they will encounter a vertical splicing cut-off portion 213 set at the end of the splicing guide 212. Since the splicing cut-off portion 213 is set vertically with the splicing guide 212, it effectively forms a blocking surface, preventing the further movement of the guide rails 200 to be installed. At this time, the guide rails 200 to be installed are exactly located at the predetermined position at the center of the splicing body 21, or are in a ready state for docking with the guide rails 200 to be installed at the other end.

[0107] To further illustrate, the side edge of the splicing guide portion 212 is flush with the side edge of the splicing body 21. Figure 2-3 As shown in Figures 7-8, when the splicing body 2 is installed in the clamping space on the spliced ​​guide rail 100, the guide rail latches on both sides will abut against the adjacent splicing guides 212, further ensuring the stable connection between the splicing body 21 and the spliced ​​guide rail 100, and providing a solid foundation for the subsequent sleeve operation. When the guide rail 200 to be installed 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 guide rail 200 to be installed can feel a smooth and continuous transition, so that it is easier to maintain a straight and stable moving trajectory. This design reduces the friction, jamming or offset caused by uneven sides, making the installation process smoother. At the same time, the flush side design also helps to improve the overall strength and stability of the splicing structure. When subjected to external force, the splicing body 21 and the splicing guide 212 can bear the load together as a whole, reducing the risk of damage caused by local stress concentration.

[0108] To further illustrate, the coding assembly 3 includes a coding connection member 31, a coding direction adjustment member 32, a coding height adjustment member 33 and a coding fastener 34;

[0109] The lower end of the compression code connection member 31 is clamped on the upper end of the guide rail 200 to be installed, and the compression code connection member 31, the compression code direction adjustment member 32 and the compression code height adjustment member 33 are installed on the guide rail 200 to be installed from bottom to top in sequence through the compression code fastener 34, and the compression code direction adjustment member 32 and the compression code height adjustment member 33 can form four directions with the guide rail 200 to be installed with the compression code fastener 34 as the rotation axis;

[0110] The code pressing direction adjusting member 32 comprises a code pressing portion 321 and a code pressing position adjusting portion 322, one side of the code pressing portion 321 is fixedly connected to the code pressing position adjusting portion 322, the code pressing portion 321 and the code pressing position adjusting portion 322 are vertically arranged, the code pressing portion 321 is rotatably mounted on the upper end of the code pressing connection member 31 with the code pressing fastener 34 as a rotating shaft, the inner side surface of the code pressing position adjusting portion 322 is in contact with the side surface of the code pressing connection member 31 in one direction, and the outer side surface of the code pressing position adjusting portion 322 is protruding with a plurality of code pressing height locking teeth 323;

[0111] The compression code height adjustment member 33 includes a compression code pressing plate 331 and a compression code height adjustment portion 332, one side of the compression code pressing plate 331 is fixedly connected to the compression code height adjustment portion 332, the compression code pressing plate 331 and the compression code height adjustment portion 332 are vertically arranged, and the bottom end of the compression code height adjustment portion 332 is protruding with a compression code fixing tooth 333, the compression code fixing tooth 333 can be mutually abutted with the guide rail surface of the guide rail 200 to be installed or one of the compression code height teeth 323 can be mutually engaged, so that the compression code pressing plate 331 and the partial guide rail surface at the upper end of the guide rail 200 to be installed form compression code placement cavities 30 of different heights, and the compression code placement cavity 30 is used to place photovoltaic components.

[0112] like Figure 2-3 As shown, the working principle of this universal pressure code 3 is based on the flexible coordination and adjustment function between its components, aiming to adapt to the installation requirements of photovoltaic components at different heights and angles. The specific working principle is as follows:

[0113] First, the compression code connection member 31 is initially fixed to the upper end of the guide rail 200 to be installed by clamping its lower end, which serves as the basic support of the entire compression code device. Next, the compression code direction adjustment member 32 and the compression code height adjustment member 33 are sequentially installed on the compression code connection member 31, and the compression code fastener 34 is used to sequentially penetrate the corresponding holes to install the compression code connection member 31, the compression code direction adjustment member 32 and the compression code height adjustment member 33 from bottom to top on the guide rail 200 to be installed. The compression code pressing part 321 of the compression code direction adjustment member 32 uses the compression code fastener 34 as the rotation axis, and can be rotated relative to the compression code connection member 31 and the guide rail 200 to be installed, thereby adjusting the installation direction between the compression code position adjustment part 322 and the guide rail 200 to be installed, such as Figure 3-4 As shown. Since the inner side surface of the coding position adjustment part 322 is in contact with the coding connection part 31, and the outer side surface is provided with a coding height latch 323, this design allows the coding direction adjustment part 32 to flexibly adjust its direction while maintaining a certain stability. Secondly, the coding pressing plate 331 of the coding height adjustment part 33 is vertically arranged with the coding height adjustment part 332, and the coding placement cavity 30 is formed between the coding pressing plate and the upper end of the guide rail 200 to be installed. The coding fixing latch 333 at the bottom end of the coding height adjustment part 332 can be selected to engage with different coding height latches 323 on the coding direction adjustment part 32. It is only necessary to place the photovoltaic component to be installed in the coding placement cavity 30, and according to the height of the photovoltaic component, select a latch with a suitable height through the coding fixing latch 333 to engage, so that the height of the coding placement cavity 30 formed between the coding pressing plate 331 and the upper end of the guide rail 200 to be installed can be adjusted, as shown in FIG. Figure 5-7 Finally, after determining the installation direction and installation height of the photovoltaic assembly to be installed on the guide rail to be installed, the photovoltaic assembly is stably installed on the guide rail 200 to be installed through the pressing effect of the code pressing plate 331 and the fastening effect of the code pressing fastener.

[0114] In summary, the beneficial effects of the coding component 3 in the present invention are as follows: 1. Flexible and adaptable: Through the flexible cooperation of the coding direction adjustment part and the coding height adjustment part, it can effectively adapt to the installation requirements of photovoltaic components of different heights and angles, thereby improving the flexibility and versatility of installation. 2. Simple structure: The entire device is composed of a small number of basic components, with a concise and clear design, which is convenient for production, installation and maintenance. 3. Easy to operate: The user can quickly complete the angle and height adjustment of the photovoltaic component through simple rotation and snap-on operations, which greatly reduces the installation difficulty and time cost. 4. Improve installation efficiency: Since the installation process is simple and quick, and can adapt to photovoltaic components of various specifications at one time, the installation efficiency of the photovoltaic system can be significantly improved. 5. High cost-effectiveness: The coding device is low-cost and easy to popularize and promote, which helps to reduce the overall construction cost of the photovoltaic system and improve the economic benefits of the project.

[0115] To further explain, the cross-section of the guide rail 200 to be installed is concave-shaped, and two first guide rail clamping parts 2003 are provided at the upper end notch of the guide rail 200 to be installed, and the first guide rail clamping parts 2003 are arranged opposite to each other and are not connected, and the upper end notch of the guide rail 200 to be installed and the two first guide rail clamping parts 2003 form a clamping groove; the pressure code connector 31 includes a pressure code connection fixing part 311; pressure code connection clamping parts 312 are respectively extended on both sides of the lower end of the pressure code connection fixing part 311, and the pressure code connection clamping parts 312 are clamped with the clamping groove.

[0116] like Figure 2-3As shown in Figures 9-11, after further refining the design of the code pressing connector 31, the code pressing connector 31 includes a code pressing connection fixing portion 311 and code pressing connection clamping portions 312 extending from both sides of the lower end of the clamping portion 331. This design enables the code pressing connector 31 to be more firmly clamped with the clamping groove of the guide rail 200 to be installed, thereby enhancing the stability and reliability of the code pressing connector 31 and the guide rail 200 to be installed. The specific working principle is as follows:

[0117] The compression code connection fixing part 311 is the main part of the compression code connection part 31, which is responsible for bearing and transmitting the clamping force from the compression code direction adjustment part 32, the compression code height adjustment part 33 and the compression code fastener 34. At the same time, it also provides a stable support foundation for the compression code connection clamping part 312. The compression code connection clamping part 312 extends from both sides of the lower end of the compression code connection fixing part 311, and its shape and size match the clamping groove of the guide rail. During the installation process, the compression code connection clamping part 312 is inserted and clamped in the clamping groove to form a stable mechanical connection.

[0118] To further explain, the compression code connection card portion 312 includes a compression code connection hook 313 , and the compression code connection hook 313 is protruding outward along the extension direction of the compression code connection card portion 312 .

[0119] like Figure 2-3 As shown in Figures 9-11, the code pressing connection card portion 312 includes a code pressing connection hook 313, which is protruded outwardly along the extension direction of the code pressing connection card portion 312. This design enables the code pressing connection card portion 312 to be more effectively connected with the connecting groove of the guide rail 200 to be installed, thereby enhancing the stability and reliability of the connection.

[0120] First, the code pressing connection hooks 313 are key components on the code pressing connection card portion 312, and they protrude outward to form a "barb" effect. When the code pressing connection card portion 312 is inserted into the clamping groove, as the code pressing connection card portion 312 goes deeper, the code pressing connection hooks 313 gradually unfold and contact the side walls of the clamping groove, and finally are completely clamped together. These code pressing connection hooks 313 can be tightly clamped on the side walls of the clamping groove to form a mechanical lock. More importantly, due to the protruding design of the code pressing connection hooks 313, they can provide additional resistance when subjected to external force, preventing the code pressing connection card portion 312 from accidentally falling out of the clamping groove. This design significantly improves the stability and reliability of the connection.

[0121] To further explain, a code-enhancing resistance pattern 314 is provided inside the code-enhancing connection card portion 312 .

[0122] like Figure 2-3As shown in Figures 9-11, specifically, the compression code resistance increasing lines 314 are a series of uneven textures or grooves engraved or pressed inside the compression code connection card portion 312. These compression code resistance increasing lines 314 can generate additional friction when in contact with the compression code fastener 34, preventing the compression code fastener 34 from sliding or disengaging when subjected to external force, thereby further enhancing the stability and reliability of the connection.

[0123] For further explanation, the coding plate 331 has a plurality of coding serrations 334 on one side facing the guide rail 200 to be installed, and the plurality of coding serrations 334 extend in the horizontal direction of the coding plate 331 , and the coding serrations 334 at the end do not exceed the installation position of the coding fastener 34 .

[0124] like Figure 2-3 As shown in Figures 9-11, in the design of the coding height adjustment member 33, a coding plate 331 is provided with a plurality of coding serrations 334 on one side facing the guide rail 200 to be installed, and these coding serrations extend along the horizontal direction of the coding plate 331. The working principle of this design is mainly reflected in the following aspects:

[0125] When the coding plate 331 is fastened to the photovoltaic module to be installed, the coding serrations 334 thereon will come into close contact with the surface of the photovoltaic module, forming multiple bite points. These bite points not only increase the friction between the coding plate 331 and the photovoltaic module, but also make the position of the coding 331 on the photovoltaic module more stable, and not easy to slide or loosen due to external forces. Secondly, the design of the coding serrations 334 enables the coding plate 331 to fit more accurately with the surface of the guide rail, especially when the position of the photovoltaic module needs to be fine-tuned. The user can adjust the position of the photovoltaic module so that the coding serrations 334 on the coding plate 331 are aligned with the specific position of the photovoltaic module, and then the coding plate 331 and the photovoltaic module are firmly fixed to the guide rail 200 to be installed by the coding fasteners 34 such as screws, bolts, etc. Finally, the coding serrations 334 at the end of the coding plate 331 are specially designed not to exceed the installation position of the coding fasteners 34. This design ensures that the compression code fastener 34 will not be interfered by the compression code serrations 334 during installation, thereby ensuring smooth installation and effective fastening of the compression code fastener 34. At the same time, it also avoids unnecessary wear or damage to the compression code fastener 34 by the compression code serrations 334.

[0126] Further explanation, the coding plate 331 is provided with a coding protection portion 335 protruding toward one side of the guide rail 200 to be installed, and the protruding height of the coding protection portion 335 is higher than the protruding height of the coding serration 334. The coding protection portion 335 is arranged close to the coding serration 334 at the end, and the coding protection portion 335 does not exceed the installation position of the coding fastener 34.

[0127] like Figure 2-3 As shown in Figures 9-11, in a further refined design of the code pressing height adjusting member 33, the code pressing plate 331 is provided with not only a plurality of code pressing serrations 334 but also a protruding code pressing protection portion 335 on the side facing the guide rail 200 to be installed. The working principle of this design is mainly reflected in the following aspects:

[0128] The main function of the compression code protection part 335 is to protect the compression code fastener 34 located near it from external damage. Since the compression code fastener 34, such as screws, bolts, etc., is a key component connecting the compression code plate 331 and the guide rail 200 to be installed, its integrity and stability are crucial to the installation of the entire photovoltaic module. The compression code protection part 335 reduces the risk of accidental collision or scratching of the compression code fastener 34 during installation, use and maintenance by means of physical isolation. More importantly, the compression code protection part 335 is arranged close to the compression code serration 334 located at the end, and its design does not exceed the installation position of the compression code fastener 34. This layout ensures that the compression code protection part 335 provides protection while also providing positioning for the photovoltaic module to be installed because the protruding height of the compression code protection part 335 is higher than the protruding height of the compression code serration 334. The photovoltaic module can abut on the compression code protection part 335 without worrying about collision with the compression code fastener 34.

[0129] To further illustrate, the connection assembly 6 includes an L-shaped connection member 61, and the L-shaped connection member 61 includes an adjustment portion 611 and a connection portion 612 that are vertically disposed to each other;

[0130] The mounting assembly 5 includes a first mounting member 51 and a second mounting member 52. The first mounting member 51 and the second mounting member 52 are relatively movable. An adjustable mounting opening 50 is formed between the first mounting member 51 and the second mounting member 52. The adjusting member 62 is used to adjust the relative movement between the first mounting member 51 and the second mounting member 52, and to fixedly connect the adjusting portion 611 and the first mounting member 51. The mounting opening 50 is used to install the guide rail 200 to be installed.

[0131] The connecting portion 612 is fixedly connected to one end of the supporting assembly 4, one end of the clamping assembly 7 and one end of the fixing assembly 8 through a connecting piece 63, respectively; the other end of the supporting assembly is installed on an external ceramic tile roof, the other end of the clamping assembly 7 is installed on an external metal tile roof, and the other end of the fixing assembly 8 is installed on an external asphalt tile roof.

[0132] like Figure 12-24As shown, specifically, one side surface of the first mounting member 51 protrudes outward to form a first horizontal mounting portion 511, one end of the first horizontal mounting portion 511 away from the first mounting member 51 is bent upward to form a first vertical mounting portion 512, and the other side surface of the first mounting member 51 protrudes outward to form a first fitting portion 513, and a first mounting through hole 5a is opened in the middle of the first mounting member 51;

[0133] One side surface of the second mounting member 52 protrudes outward from top to bottom to form a second vertical mounting portion 521 and a second horizontal mounting portion 522. The upper end surface of the second horizontal mounting portion 522 is a horizontal surface, and the lower end surface of the second horizontal mounting portion 522 is a fitting surface. A second mounting through hole 5b is opened in the middle of the second mounting member 52.

[0134] The upper mating surface of the first mating portion 513 and the mating surface of the second horizontal mounting portion 522 are in contact with each other, and the upper mounting surface of the first horizontal mounting portion 511 and the horizontal surface of the second horizontal mounting portion 522 are in contact with the lower wall surface of the guide rail 200 to be installed;

[0135] A mounting opening 50 is formed between the first vertical mounting portion 512 and the second vertical mounting portion 521, and the mounting opening 50 is used to mount the guide rail 200 to be mounted; an adjusting through hole 6a is opened in the middle of the adjusting portion 611; the adjusting member 62 includes an adjusting bolt 621, an adjusting nut 622 and an adjusting spring 623, the adjusting bolt 621 passes through the adjusting through hole 6a, the second mounting through hole 5b and the first mounting through hole 5a and is threadedly connected to the adjusting nut 622, and the adjusting bolt 621 is sleeved with the adjusting spring 623, and the two ends of the adjusting spring 623 are respectively abutted against the first mounting member 51 and the second mounting member 52.

[0136] like Figure 12-24 As shown, the mounting assembly 5 is designed for photovoltaic brackets on ceramic tile roofs, aiming to achieve efficient, flexible and stable installation of the guide rail 200 to be installed. Its working principle is as follows:

[0137] First, combine the first mounting member 51 and the second mounting member 52. The first mating portion 513 of the first mounting member 51 and the mating surface of the second horizontal mounting portion 522 of the second mounting member 52 are fitted and abutted against each other, and at the same time, the upper mounting surface of the first horizontal mounting portion 511 of the first mounting member 51 and the horizontal surface of the second horizontal mounting portion 522 of the second mounting member 52 form the same horizontal plane. Next, place the guide rail 200 to be installed on the same horizontal plane of the first horizontal mounting portion 511 and the second horizontal mounting portion 522. Since the same horizontal plane design of the two takes into account the fit with the lower wall of the guide rail, it can ensure that the guide rail is firmly supported, and the left wall and the right wall of the guide rail are respectively located between the first vertical mounting portion 512 of the first mounting member 51 and the second vertical mounting portion 521 of the second mounting member 52, to avoid shaking or falling off during installation and use. Finally, through the action of the adjusting bolt 621, the adjusting nut 622 and the adjusting spring 623 of the adjusting member 62, the adjusting bolt 621 is passed through the adjusting through hole 6a, the first mounting through hole 5a and the second mounting through hole 5b in sequence, and is threadedly connected with the adjusting nut 622. During the passing of the adjusting bolt 621, the adjusting spring 623 is sleeved on the adjusting bolt 621, and its two ends are respectively abutted against the first mounting member 51 and the second mounting member 52. By rotating the adjusting nut 622, the first fitting portion 513 of the first mounting member 51 and the fitting surface of the second horizontal mounting portion 522 of the second mounting member 52 move relative to each other, so that the relative position between the first mounting member 51 and the second mounting member 52 can be adjusted, that is, the size of the mounting opening 50 of the mounting assembly 5 can be adjusted, so that the first vertical mounting portion 512 and the second vertical mounting portion 521 are clamped on the two sides of the guide rail 200 to be installed, so as to achieve a stable clamping effect.

[0138] The setting of the adjustment spring 623 not only provides elastic buffering during the installation process, but also maintains a certain pressure after tightening to ensure a close fit between the installation component 5 and the guide rail. At the same time, this design is also convenient for subsequent maintenance and adjustment work. If the position of the guide rail needs to be adjusted or repaired, it can be easily achieved by loosening the adjustment nut 622.

[0139] For further explanation, one end of the first vertical mounting portion 512 away from the first horizontal mounting portion 511 is bent to form a bending portion 514, and a first clamping groove 515 is formed between the first vertical mounting portion 512 and the bending portion 514; a second clamping groove 523 is formed by a depression between the second vertical mounting portion 521 and the second horizontal mounting portion 522; the left and right outer walls of the guide rail 200 to be installed are respectively provided with second guide rail clamping portions 2001 along their length directions; the two second guide rail clamping portions 2001 of the guide rail 200 to be installed are respectively clamped in the first clamping groove 515 and the second clamping groove 523.

[0140] like Figure 12-24 As shown, specifically, the left and right outer walls of the guide rail 200 to be installed are respectively provided with second guide rail clamping parts 2001 along the length direction thereof, and these second guide rail clamping parts 2001 are designed to match the first clamping groove 515 and the second clamping groove 523 in the installation assembly 5. During the installation process, the two second guide rail clamping parts 2001 of the guide rail are respectively aligned with the first clamping groove 515 of the first installation member 51 and the second clamping groove 523 of the second installation member 52, and then gently pushed in until the second guide rail clamping parts 2001 are completely clamped in the first clamping groove 515 and the second clamping groove 523. This clamping method not only simplifies the installation steps, but also improves the stability and efficiency of the installation.

[0141] To further explain, the other side surface of the first mounting member 51 protrudes outward to form a first abutment portion 516, the first abutment portion 516 is located below the first fitting portion 513, and the first abutment portion 516 is bent at one end away from the first mounting member 51 to form a first termination portion 517; one side surface of the second mounting member 52 protrudes outward to form a second abutment portion 524, the second abutment portion 524 is located below the second horizontal mounting portion 522, and the second abutment portion 524 is bent at one end away from the second mounting member 52 to form a second termination portion 525; the first termination portion 517 abuts against the second abutment portion 524, and the first termination portion 517 can be mutually engaged with the second termination portion 525.

[0142] like Figure 12-24 As shown, specifically, the first abutting portion 516 is bent at one end away from the first mounting member 51 to form a first terminating portion 517, which is designed with a snap-fit ​​structure, such as a buckle, a slot or a hook structure. The second abutting portion 524 is bent at one end away from the second mounting member 52 to form a second terminating portion 525, which is also designed with a snap-fit ​​structure matching the first terminating portion 517.

[0143] During the adjustment process of the adjusting member 62, the first end portion 517 and the second end portion 525 will move closer to or farther from each other. When the first end portion 517 and the second end portion 525 move closer to each other, the clamping structures of the two are engaged with each other to achieve a stable clamping connection. This clamping method not only enhances the stability of the mounting assembly 5, but also plays a limiting role, which can prevent the adjusting member 62, such as the adjusting bolt 621 and the adjusting nut 622, from being too loose during the adjustment process, resulting in an excessive distance between the first mounting member 51 and the second mounting member 52, thereby making the guide rail installation unstable.

[0144] For further explanation, the adjusting portion 611 has an adjusting tooth surface 613 on one side facing the mounting assembly 5 ; the second mounting member 52 has an installing tooth surface 526 on one side facing the adjusting portion 611 , and the installing tooth surface 526 is engaged with the adjusting tooth surface 613 .

[0145] like Figure 12-24 As shown, during the installation process, the adjustment tooth surface 613 of the adjustment part 611 is aligned with the installation tooth surface 526 of the second support member, and gently pushed to make the tooth surfaces therebetween engage with each other. This engagement connection method not only provides a stable support, but also allows the vertical distance between the installation component 5 and the support component 4 to be adjusted within a certain range according to actual installation requirements.

[0146] To further illustrate, the support assembly 4 includes a first support structure 41;

[0147] The first supporting structure 41 includes a first mounting seat 411 and a first hook member 412;

[0148] The first mounting seat 411 includes a first base 413, the first base 413 is divided into a fixing area and an adjustment area, and the fixing area is provided with a plurality of first fixing holes 41a arranged at intervals;

[0149] The adjustment area is protruding upwards and is provided with two adjustment seats 414, and the facing surfaces of the two adjustment seats 414 are provided with a plurality of intervally arranged clamping grooves 415;

[0150] The first hook member 412 has a first assembly hole 41b at its upper end, and two clamping seats 416 at its lower end. The opposite surfaces of the two clamping seats 416 are bent outward to form a clamping hook 417.

[0151] The two hooks 417 are engaged in any one of the engaging slide grooves 415;

[0152] The connecting member 63 includes a connecting bolt 631 and a connecting nut 632, and a connecting through hole 6b is opened in the middle of the connecting portion 612;

[0153] One end of the connecting bolt 631 passes through the connecting through hole 6b of the connecting portion 612 and the first assembly hole 41b of the first hook member 412 in sequence and is threadedly fixed to the connecting nut 632 to fix the L-shaped connecting member 61 and the first hook member 412 together.

[0154] like Figure 12-14 As shown, the first support structure 41 is specially designed for ceramic tile roofs, aiming to provide a universal installation solution - the first support structure 41 that can be adjusted according to the size and position of the ceramic tiles.

[0155] First, the first base 413 of the first mounting seat 411 may be provided with a plurality of first fixing holes 41a arranged at intervals so that the first base 413 can be locked on the ceramic tile roof by passing through the external screws of the first fixing holes 41a, so that the locking position of the first mounting seat 411 and the ceramic tile roof can be flexibly adjusted. Next, according to the size and position requirements of the ceramic tile, the position of the first hook 412 in the clamping slot 415 of the adjustment seat 414 is adjusted. Since the clamping slot 415 is arranged at intervals, the first hook 412 can be accurately adjusted in the front and back and up and down directions by selecting a suitable clamping position. This flexibility ensures that the installation assembly can adapt to the installation requirements of ceramic tile roofs of different sizes and positions. Once the position of the first hook 412 is adjusted, its hook 417 will be clamped in the clamping slot 415 of the adjustment seat 414, thereby maintaining a stable fixed state. This clamping method is not only simple and fast, but also can ensure the stability of the first hook 412 during the installation process. Finally, the L-shaped connector 61 is fixedly connected to the first hook member 412 using the connector 63. One end of the connecting bolt 631 passes through the connecting through hole 6b of the L-shaped connector and the first assembly hole 41b of the first hook member 412, and then is threadedly fixed with the connecting nut 632. This step ensures a stable connection between the L-shaped connector and the first hook member 412, thereby achieving complete assembly of the entire first support structure 41.

[0156] To further illustrate, the first support structure 41 further includes a first reinforcing connecting bolt 418;

[0157] A reinforcement seat 419 is connected between the facing surfaces of the two clamping seats 416, and the reinforcement seat 419 is provided with a first reinforcement connection through hole 41c; the first bent hook member 412 is provided with a second reinforcement connection through hole 41d at a position opposite to the reinforcement seat 419; one end of the first reinforcement connection bolt 418 is threadedly connected with the second reinforcement connection through hole 41d of the first bent hook member 412 and the first reinforcement connection through hole 41c of the reinforcement seat 419 in sequence, and the first bent hook member 412 and the reinforcement seat 419 are fixedly connected.

[0158] like Figure 12-14As shown, further, a reinforcement seat 419 is added between the facing surfaces of the two clamping seats 416 to provide additional support and stability for the first hook member 412. A first reinforcement connection through hole 41c is provided on the reinforcement seat 419, and a second reinforcement connection through hole 41d is provided at the position of the first hook member 412 facing the reinforcement seat 419. Then, the first hook member 412 and the reinforcement seat 419 are fixedly connected together using a first reinforcement connection bolt 418. One end of the first reinforcement connection bolt 418 passes through the second reinforcement connection through hole 41d of the first hook member 412 and the first reinforcement connection through hole 41c of the reinforcement seat 419 in turn, and is threadedly connected with a nut. This connection method not only enhances the connection strength between the first hook member 412 and the reinforcement seat 419, but also improves the stability of the entire mounting structure. This design makes the mounting assembly more stable and reliable when facing external forces such as wind pressure and snow pressure.

[0159] To further illustrate, the support assembly 4 includes a second support structure 42;

[0160] The second supporting structure 42 includes a second mounting seat 421, a second hook 422, a second fixing bolt 423 and a second fixing nut 424;

[0161] The second mounting seat 421 includes a second base 425 and a mounting plate 426. The mounting plate 426 is provided with a plurality of mounting holes 42a arranged at intervals. The second base 425 is provided with a plurality of second fixing holes 42b arranged at intervals.

[0162] An upper assembly hole 42c is formed at the upper end of the second hook member 422, and a lower assembly hole 42d is formed at the lower end of the second hook member 422. Both the upper assembly hole 42c and the lower assembly hole 42d are long holes.

[0163] One end of the second fixing bolt 423 passes through the mounting hole 42a of the mounting plate 426 and the lower assembly hole 42d of the second hook member 422 in sequence, and is threadedly fixed to the second fixing nut 424, thereby fixing the second mounting seat 421 and the second hook member 422;

[0164] The connecting member 63 includes a connecting bolt 631 and a connecting nut 632, and a connecting through hole 6b is opened in the middle of the connecting portion 612;

[0165] One end of the connecting bolt 631 passes through the connecting through hole 6b of the connecting portion 612 and the upper assembly hole 42c of the second hook member 422 in sequence and is threadedly fixed to the connecting nut 632 to fix the L-shaped connecting member 61 and the second hook member 422 together.

[0166] like Figure 15-17As shown, the second support structure 42 is mainly used to firmly install the purlins of the ceramic tile roof at a predetermined position, and can be adjusted forward and backward according to the size and position requirements of the ceramic tile. The following is a detailed description of the working principle:

[0167] First, the second base 425 of the second mounting seat 421 can be provided with a plurality of fixed holes arranged at intervals so that the second base 425 can be locked on the ceramic tile roof by screws passing through the fixed holes, so that the locking position of the second mounting seat 421 and the ceramic tile roof can be flexibly adjusted. Then, according to the size and position requirements of the ceramic tile, the position of the second hook 422 on the mounting plate 426 is adjusted. Since the upper assembly hole 42c and the lower assembly hole 42d are both long holes, the second hook 422 can be moved within a certain range to meet different installation requirements. Once the position is determined, the second fixing bolt 423 is used to pass through one of the first mounting holes 42a of the mounting plate 426 and the lower assembly hole 42d of the second hook 422 in turn, and is threadedly fixed with the second fixing nut 424, so that the second mounting seat 421 and the second hook 422 are firmly connected together. Finally, the L-shaped connector is fixedly connected to the second hook 422 using the connecting bolt 631 and the connecting nut 632. One end of the connecting bolt 631 passes through the connecting through hole 6b of the connecting part and the upper assembly hole 42c of the second hook member 422 in sequence, and is threadedly fixed with the connecting nut 632. This connection method not only ensures a stable connection between the L-shaped connecting member and the second hook member 422, but also allows the L-shaped connecting member to be fine-tuned within a certain range to adapt to different installation heights and position requirements.

[0168] To further explain, the second hook component 422 includes a first Z-type connecting component 427, a second Z-type connecting component 428, a third fixing bolt 429 and a third fixing nut 420; the first Z-type connecting component 427 has an upper assembly hole 42c at one end, and a first connection assembly hole 42e at the other end, and the first connection assembly hole 42e is a long hole; the second Z-type connecting component 428 has a lower assembly hole 42d at one end, and a second connection assembly hole 42f at the other end; one end of the third fixing bolt 429 passes through the first connection assembly hole 42e of the first Z-type connecting component 427 and the second connection assembly hole 42f of the second Z-type connecting component 428 in sequence, and is then threadedly fixed to the third fixing nut 420, and the first Z-type connecting component 427 and the second Z-type connecting component 428 are fixedly connected.

[0169] like Figure 15-17As shown, since the first connection assembly hole 42e is a long hole, the first Z-shaped connection sub-component 427 and the second Z-shaped connection sub-component 428 can be relatively moved and adjusted in the up and down directions within a certain range. This design enables the second hook member 422 to be accurately adjusted according to the size of the ceramic tile and the position requirements of the purlin during the installation process, thereby improving the flexibility and accuracy of the installation.

[0170] To further illustrate, the support assembly 4 includes a third support structure 43;

[0171] The third supporting structure 43 includes a self-tapping screw 431, and the outer wall surface of the self-tapping screw 431 is respectively provided with a first thread 432 and a second thread 433 from top to bottom, and the pitch of the first thread 432 is smaller than the pitch of the second thread 433;

[0172] The connecting member 63 includes an upper connecting nut 633 and a lower connecting nut 634, and a connecting through hole 6b is opened in the middle of the connecting portion 612;

[0173] The self-tapping screw 431 passes through the upper connection nut 633, the connection through hole 6b and the lower connection nut 634 in sequence, and the upper connection nut 633 and the lower connection nut 634 are respectively threadedly connected with the first thread 432.

[0174] The self-tapping screw 431 is also threadedly connected to a limit nut 434 and a limit protection sleeve 435 , and the limit nut 434 and the limit protection sleeve 435 are located below the lower connection nut 634 .

[0175] like Figure 18-19 As shown, this mounting assembly 5 is designed for ceramic tile roofs and aims to provide a universal mounting solution - the third support structure 43, which does not need to be adjusted according to the size and position of the ceramic tiles. The third support structure 43 is designed to be directly fixed to the purlins of the ceramic tile roof. This design not only eliminates the steps of complex adjustments according to the specific size and position of the ceramic tiles, but also greatly simplifies the installation process. It can also ensure that the photovoltaic bracket can be firmly and quickly installed on the purlins of the ceramic tile roof. Its working principle is as follows:

[0176] First, the self-tapping screw 431 is a key component for connecting the purlin and the installation component 5, and its outer wall surface is respectively provided with a first thread 432 and a second thread 433 from top to bottom. The pitch of the first thread 432 is small, providing a stronger tightening force and a more precise adjustment capability; the pitch of the second thread 433 is large, which is convenient for quickly passing through the material and achieving a preliminary tightening effect. Secondly, the connecting member 433 includes an upper connecting nut 633 and a lower connecting nut 634, which cooperate with the self-tapping screw 431 through the connecting through hole 6b of the connecting part 612. During the assembly process, the self-tapping screw 431 first passes through the upper connecting nut 633, then passes through the connecting through hole 6b, and finally passes through the lower connecting nut 634. The upper connecting nut 633 and the lower connecting nut 634 are respectively threadedly connected with the first thread 432 of the self-tapping screw 431 to achieve a stable fixation. Finally, in order to ensure the stability and safety of the installation component 5, the self-tapping screw 431 is also threadedly connected with the limit nut 434 and the limit protection cover 435. The limit nut 434 is located below the lower connection nut 634 to prevent the self-tapping screw 431 from loosening under vibration or external force. The limit protection sleeve 435 further wraps the limit nut 434 and the end of the self-tapping screw 431 to provide additional protection to prevent corrosion or damage caused by long-term exposure to harsh environments.

[0177] To further explain, the clamping assembly 7 includes a first clamp 71, a second clamp 72 and a clamping connector 73. The connecting portion 612 is fixedly connected to the first clamp 71 via the connector 63. The first clamp 71 and the second clamp 72 are relatively movable. A clamping opening 70 of adjustable size is formed between the first clamp 71 and the second clamp 72. The clamping connector 73 is used to adjust the relative movement between the first clamp 71 and the second clamp 72. The clamping opening 70 is used to install a metal tile roof.

[0178] like Figure 21-22 As shown, the present invention realizes the stable clamping of the metal tile roof and the flexible installation of the guide rail through the ingenious component design. Its working principle is as follows:

[0179] First, the mounting assembly 5 is used as the base part of the bracket, and the mounting opening 50 opened thereon is used to install the guide rail 200 to be installed. The adjusting portion 611 of the L-shaped connector 61 is connected to the mounting assembly 5 through the adjusting member 62. The adjusting member 62 here not only plays a fixing role, but also can change the size of the mounting opening 50 by adjusting the tension to adapt to guide rails of different sizes. Secondly, the connecting portion 612 of the L-shaped connector 61 is fixedly connected to the upper end of the first clamp 71 through the connecting member 63. This design forms a stable connection between the mounting assembly 5 and the clamping assembly 7, and also provides a reliable support point for the clamping assembly 7. Finally, the first clamp 71 and the second clamp 72 are connected by the clamping connector 73 to form a clamping opening 70 with adjustable size. This clamping opening 70 is designed to clamp the crest or other stable structure of the metal tile roof. By adjusting the relative position of the first clamp 71 and the second clamp 72 through the clamping connector 73, the clamping of metal tile roofs of different shapes and sizes can be achieved.

[0180] In summary, the beneficial effects of the clamping assembly 7 of the present invention are as follows:

[0181] 1. High flexibility: By adjusting the size of the mounting opening 50 of the mounting component 5 by the adjusting member 62, and by flexibly clamping the metal tile roof by the clamping opening 70 of the clamping component 7, the photovoltaic bracket can be applied to guide rails and metal tile roofs of different sizes and shapes, greatly improving the flexibility and versatility of installation. 2. Stable and reliable: The design of the L-shaped connector 61 forms a stable triangular support structure between the mounting component 5 and the clamping component 7, enhancing the overall stability of the bracket. At the same time, the tight clamping of the clamping component on the metal tile roof also ensures the safety of the bracket under severe weather conditions. 3. Convenient installation: The components of the photovoltaic bracket are reasonably designed, and the installation process is simple and quick. It does not require complicated construction steps and professional skills, which greatly reduces the installation cost and difficulty.

[0182] To further explain, the first clamp 71 includes a first horizontal support plate 711 and a first vertical support plate 712 which are vertically arranged, and an arc-shaped groove 713 is provided at the connection between the first horizontal support plate 711 and the first vertical support plate 712; the second clamp 72 includes a second horizontal support plate 721 and a second vertical support plate 722 which are vertically arranged, and an arc-shaped engaging portion 723 is provided at one end of the second horizontal support plate 721 away from the second vertical support plate 722; the arc-shaped engaging portion 723 of the second clamp 72 is engaged and connected with the arc-shaped groove 713 of the first clamp 71.

[0183] like Figure 21-22As shown, when the first clamp 71 and the second clamp 72 need to be connected together, the arc-shaped fitting portion 723 of the second clamp 72 is aligned with the arc-shaped slot 713 of the first clamp 71, and the second clamp 72 is pushed along the arc direction of the slot until the arc-shaped fitting portion 723 is completely embedded in the arc-shaped slot 713. Since the arcs of the arc-shaped slot 713 and the arc-shaped fitting portion 723 match, the two can be tightly fitted together to form a preliminary and stable hinged structure. Because the arcs of the arc-shaped slot 713 and the arc-shaped fitting portion 723 are designed to have a certain elastic range, the clamping opening 70 between the first clamp 71 and the second clamp 72 can be adjusted to adapt to metal tile roofs of different sizes and shapes. This further enhances the scope of application and flexibility of the photovoltaic bracket.

[0184] To further explain, a vertical tooth panel 714 is provided at one end of the first vertical support plate 712 away from the first horizontal support plate 711; an arc-shaped clamping plate 724 is provided at one end of the second vertical support plate 722 away from the second horizontal support plate 721; the vertical tooth panel 714 and the arc-shaped clamping plate 724 are arranged opposite to each other and form the clamping opening 70.

[0185] like Figure 21-22 As shown, specifically, the vertical tooth panel 714 of the first clamp 71 is provided with a plurality of vertically arranged tooth-like patterns on one side facing the arc-shaped clamping plate 724, so as to increase the contact area and friction with the wave crest of the metal tile roof, thereby improving the stability of the clamping. At the same time, the second clamp 72 is provided with an arc-shaped clamping plate 724, which can better fit the curve of the wave crest of the metal tile roof, further enhancing the tightness and stability of the clamping.

[0186] To further explain, the connecting member 63 includes a connecting bolt 631 and a connecting nut 632, a connecting through hole 6b is opened in the middle of the connecting portion 612; a first transverse through hole 7a is opened in the middle of the first transverse support plate 711; one end of the connecting bolt 631 passes through the connecting through hole 6b of the connecting portion 612 and the first transverse through hole 7a of the first transverse support plate 711 in sequence and is then threadedly fixed to the connecting nut 632, thereby fixing the L-shaped connecting member 61 and the first clamp 71 in fixed connection.

[0187] To further explain, the clamping connection member 73 includes a supporting connection bolt 731 and a supporting connection nut 732; a first vertical through hole 7b is opened in the middle of the first vertical support plate 712; a second vertical through hole 7c is opened in the middle of the second vertical support plate 722; one end of the supporting connection bolt 731 passes through the first vertical through hole 7b of the first vertical support plate 712 and the second vertical through hole 7c of the second vertical support plate 722 in sequence, and is then threadedly fixed to the supporting connection nut 732, thereby fixing the first clamp 71 and the second clamp 72 in fixed connection.

[0188] like Figure 21-22 As shown, specifically, through the threaded cooperation of the connector 63 and the clamping connector 73, a firm connection between the L-shaped connector 61, the first clamp 71 and the second clamp 72 is achieved. This connection method is not only simple in structure, but also does not require complicated construction steps and professional skills, reduces the difficulty and cost of installation, and improves installation efficiency. Moreover, the connection is reliable and can withstand greater wind and snow pressure, ensuring the overall stability and safety of the photovoltaic support system.

[0189] To further illustrate, the fixing assembly 8 comprises a fixing assembly plate 81, a fixing connection plate 82 and a fixing installation plate 83 which are connected in sequence, and the fixing assembly plate 81, the fixing connection plate 82 and the fixing installation plate 83 are formed by bending a plate body;

[0190] The connecting portion 612 is fixedly connected to the fixed assembly plate 81 through a connecting piece 63. The fixed installation plate 83 is provided with a plurality of fixed installation through holes 8a arranged at equal intervals, and one plate surface of the fixed installation plate 83 is provided with a mounting slot 831. The fixed installation plate 83 is connected to the asphalt tile roof through the mounting slot 831.

[0191] like Figure 23-24As shown, the present invention is mainly composed of a mounting assembly 5, a fixing assembly 8 and a connecting assembly 6. Among them, the L-shaped connecting member 61 in the connecting assembly 6 realizes a combination of flexibility and stability through its adjusting portion 611 and the connecting portion 612. The adjusting portion 611 is fixedly connected to the first mounting member 51, and the relative movement between the first mounting member 51 and the second mounting member 52 is controlled by the adjusting member 62, thereby forming a mounting opening 50 with adjustable size. This design allows adjustment according to the actual size of the guide rail 200 to be installed, ensuring that the guide rail 200 to be installed can be firmly installed on the photovoltaic bracket. More importantly, the fixing assembly 8 is composed of a fixed assembly plate 81, a fixed connection plate 82 and a fixed mounting plate 83, which are formed by bending a plate body to provide a stable support structure. The connecting portion 612 is fixedly connected to the fixed assembly plate 81 through the connecting member 63, thereby connecting the mounting assembly 5 to the fixing assembly 8. The multiple fixed mounting through holes 8a arranged at equal intervals on the fixed mounting plate 83 allow the bracket to be fixed to the asphalt tile roof using bolts or other fasteners. At the same time, the design of the mounting slot 831 on the fixed mounting plate 83 enables the bracket to be easily snapped onto the asphalt tile roof, further enhancing the stability and convenience of the installation.

[0192] In summary, the beneficial effects of the fixing assembly 8 in the present invention are as follows:

[0193] 1. Strong adaptability: The size of the mounting opening 50 of the photovoltaic bracket is adjustable and can adapt to rails of different sizes, which improves the versatility and practicality of the bracket. 2. Convenient installation: Through the design of the connecting component 6 and the fixing component 8, the bracket can be easily installed and fixed on the asphalt tile roof, which greatly simplifies the installation process and reduces the installation cost. 3. Stable and reliable: The bracket structure is stable and the connector design is reasonable. It can withstand various forces and moments generated when the photovoltaic system is running, ensuring the safe and stable operation of the system.

[0194] To further explain, a fixed assembly groove 811 is provided on one side of the fixed assembly plate 81 facing the connecting portion 612; a fixed protection protrusion 812 is protruded from one side of the fixed assembly plate 81 facing the connecting portion 612, and the fixed protection protrusion 812 is arranged corresponding to the fixed assembly groove 811; a through fixed assembly through hole 8b is provided between the fixed protection protrusion 812 and the fixed assembly groove 811; the connecting piece 63 includes a connecting bolt 631 and a connecting nut 632, and a connecting through hole 6b is provided in the middle of the connecting portion 612; one end of the connecting bolt 631 passes through the connecting through hole 6b of the connecting portion 612 and the fixed assembly through hole 8b of the fixed assembly plate 81 in sequence, and is then threadedly fixed to the connecting nut 632, and the L-shaped connecting piece 61 and the fixing component 8 are fixedly connected.

[0195] like Figure 23-24As shown, specifically, a firm connection between the L-shaped connector 61 and the fixed component 8 is achieved through the threaded fit of the connector 63. This connection method is not only simple in structure, but also does not require complicated construction steps and professional skills, reduces the difficulty and cost of installation, and improves installation efficiency. In order to further enhance the stability of the connection and protect the connector 63 from erosion by the external environment, a fixed protective protrusion 812 is also protruded from the side of the fixed assembly plate 81 facing the connection part 612. The fixed protective protrusion 812 corresponds closely to the fixed assembly groove 811, and can tightly wrap a part of the connector 63 to provide additional support and protection. The connection is reliable and can withstand greater wind and snow pressure, ensuring the overall stability and safety of the photovoltaic support system.
