Furthermore, they are difficult to assemble and disassemble, and are prone to misassembly and omissions, which can affect the operation of the photovoltaic system. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes an installation component and photovoltaic system with a small number of components and easy assembly and disassembly.

[0004] In a first aspect, this application provides an installation component for use in a photovoltaic system, comprising:

[0005] Purlins are used to install the photovoltaic modules of the photovoltaic system and form a first groove;

[0006] The first fastener is installed in the first groove;

[0007] The clamp has two opposite ends at its opening, which are provided with second fasteners for engaging with the first fastener.

[0008] When the first snap-fit ​​component and the second snap-fit ​​component are snapped together, the clamp and the purlin together form a cavity for accommodating the main shaft of the photovoltaic system.

[0009] According to the installation components of this application, by setting clamps and purlins to connect the first snap-fit ​​component and the second snap-fit ​​component, the number of components of the photovoltaic system is reduced, disassembly and assembly are easy, installation efficiency is high, and cost is low.

[0010] According to one embodiment of this application, the first card connector includes:

[0011] The substrate is mounted in the first groove and is provided with a first clearance hole;

[0012] The snap-fit ​​portion is connected to one side edge of the first clearance hole and protrudes in the direction away from the clamp relative to the substrate, and the second snap-fit ​​member passes through the first clearance hole and snaps into the snap-fit ​​portion and the substrate.

[0013] According to the mounting assembly of this application, by providing a snap-fit ​​portion on the edge of the first clearance hole of the first snap-fit ​​member that is opposite to the clamp relative to the substrate, the second snap-fit ​​member is snapped more securely with the first snap-fit ​​member, and the stability is better when the main shaft drives the mounting assembly and photovoltaic module to rotate.

[0014] According to one embodiment of this application, the snap-fit ​​portion is provided with a first guide surface from one side of the first clearance hole, and the first guide surface is inclined towards the other side closer to the first clearance hole in a direction away from the clamp.

[0015] According to the installation component of this application, by providing a first guide surface at the snap-fit ​​part, the snap-fit ​​between the second snap-fit ​​part and the first snap-fit ​​part is easier and the installation efficiency is higher.

[0016] According to one embodiment of this application, a second guide surface is provided on the side of the first clearance hole opposite to the snap-fit ​​portion, and the second guide surface is inclined toward the snap-fit ​​portion in a direction away from the clamp.

[0019] According to the mounting assembly of this application, by providing a protrusion at the end of the second snap-fit ​​member away from the clamp, it is convenient for the second snap-fit ​​member to snap onto the substrate through the protrusion after passing through the first clearance hole, thus completing the snap-fit ​​between the second snap-fit ​​member and the first snap-fit ​​member. The snap-fit ​​is secure and will not easily separate.

[0020] According to one embodiment of this application, the protrusion is provided with a third guide surface on the side away from the snap-fit ​​portion, and the third guide surface is inclined from the end away from the snap-fit ​​portion toward the substrate in a direction away from the snap-fit ​​portion.

[0021] According to the installation component of this application, by providing a third guide surface on the protrusion, the second snap-fit ​​component is easier to snap into the first snap-fit ​​component, resulting in higher installation efficiency.

[0029] According to the installation component of this application, by setting a clearance fit between the first snap-fit ​​member and the receiving groove, a certain installation error and processing error of the first snap-fit ​​member are allowed when installing the first snap-fit ​​member. At the same time, by setting the materials of the first snap-fit ​​member and the second snap-fit ​​member, the connection method between the second snap-fit ​​member and the clamp, and the connection method between the first snap-fit ​​member and the reinforcing member, the stability of the installation component is improved, and it is easy to disassemble and maintain, and the operation is convenient.

[0056] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0057] The principle of the mounting component 10 proposed in this application will be explained in detail below:

[0058] In related technologies, the purlins of photovoltaic systems are composed of many components and have a complex structure in order to prevent them from being damaged in strong winds. They also use a lot of materials, resulting in high costs. Furthermore, they are difficult to assemble and disassemble, and are prone to misassembly and omissions, which can affect the operation of the photovoltaic system.

[0059] To address this technical problem, this application provides an installation component 10, which is described below with reference to... Figures 1-8 The installation component 10 according to an embodiment of this application is described.

[0060] like Figure 1 and Figure 2 As shown, the installation component 10 of this application embodiment is applied to a photovoltaic system 1 and includes: purlin 100, first fastener 200, clamp 300 and second fastener 400.

[0061] Purlin 100 is used to install the photovoltaic modules of photovoltaic system 1.

[0062] Purlin 100 can be made of materials such as aluminum alloy or stainless steel, and no specific restrictions are made in this embodiment.

[0063] like Figure 1 As shown, the purlin 100 forms a first groove 110.

[0064] In this embodiment, the first groove 110 on the purlin 100 extends through both ends of the purlin 100, which facilitates the installation of other components and reduces the use of materials.

[0065] In some embodiments, the first groove 110 may also be provided at a local location on the purlin 100, depending on the actual installation situation.

[0066] The first connector 200 is installed in the first groove 110.

[0067] In this embodiment, the purlin 100 includes a main body 130 and a flange 140. The main body 130 forms a first groove 110 with the groove opening facing upward, which facilitates the installation of the first snap-fit ​​member 200. The flange 140 is connected to the side wall of the main body 130 away from the bottom wall, and the flange 140 is bent outward. The flange 140 is used to install photovoltaic modules.

[0068] In this embodiment, both sides of the main body 130 are provided with flanges 140. The cross-sectional shape of the purlin 100 formed by the main body 130 and the two flanges 140 is Z-shaped, which makes it easy to install photovoltaic modules.

[0069] like Figure 2 As shown, the second snap-fit ​​member 400 is disposed opposite to both ends of the opening of the clamp 300, and the second snap-fit ​​member 400 is used to snap-fit ​​with the first snap-fit ​​member 200.

[0070] In this embodiment, the second snap-fit ​​component 400 is provided with a hot-press nut 420 inside. The hot-press nut 420 has threads inside. The second snap-fit ​​component 400 is bolted to the clamp 300 through the hot-press nut 420, which has high connection strength and is easy to disassemble and assemble.

[0071] In some embodiments, the second snap-fit ​​member 400 and the clamp 300 can also be connected by snap-fit ​​or welding.

[0072] In this embodiment, the first snap-fit ​​component 200 can be a limiting spring, and the second snap-fit ​​component 400 can be a buckle.

[0073] In some embodiments, the first snap-fit ​​member 200 and the second snap-fit ​​member 400 may also be a snap-fit ​​structure such as a snap-fit ​​ring or a snap-fit ​​tongue.

[0074] like Figure 1 and Figure 2 As shown, when the first snap-fit ​​member 200 and the second snap-fit ​​member 400 are snapped together, the clamp 300 and the purlin 100 together form a cavity 500 for accommodating the main shaft 20 of the photovoltaic system 1.

[0075] In related technologies, the purlins of photovoltaic systems are composed of many components and have a complex structure in order to prevent them from being damaged in strong winds. They also use a lot of materials, resulting in high costs. Furthermore, the assembly and disassembly involve a large number of connectors, making the process difficult, time-consuming, and prone to misassembly and omissions, which can affect the operation of the photovoltaic system.

[0076] In this embodiment, the mounting component 10 has a first groove 110 on the purlin 100. A first snap-fit ​​200 is installed on the bottom wall of the first groove 110, which saves materials while ensuring structural strength and reducing costs. Two second snap-fits 400 are installed opposite each other at the opening of the clamp 300. When installing the photovoltaic system 1, the purlin 100 is located above the main shaft 20, the groove of the first groove 110 faces upward, the clamp 300 is installed from below the main shaft 20, and the second snap-fits 400 snap into the first snap-fits 200. The clamp 300 and the purlin 100 surround the main shaft 20. The installation steps are few, and the assembly and disassembly are easy. Then, the photovoltaic module is installed on the purlin 100 to complete the installation of the photovoltaic tracking bracket of the photovoltaic system 1. The installation efficiency is high.

[0077] According to the installation component 10 provided in the embodiments of this application, by setting the clamp 300 and the purlin 100 to be connected by the first snap-fit ​​member 200 and the second snap-fit ​​member 400, the number of components of the photovoltaic system 1 is reduced, the assembly and disassembly are easy, the installation efficiency is high, and the cost is low.

[0078] In some embodiments, such as Figure 3 and Figure 4 As shown, the first snap-fit ​​member 200 may include a substrate 210 and a snap-fit ​​portion 220.

[0079] In this embodiment, two first snap-fit ​​pieces 200 are spaced apart in the first groove 110.

[0080] like Figure 3 and Figure 4 As shown, the substrate 210 is mounted in the first groove 110, and the substrate 210 is provided with a first clearance hole 211.

[0081] The substrate 210 can be made of materials such as copper, stainless steel or plastic. In this embodiment, the substrate 210 can be made of plastic, which is low in cost and light in weight.

[0082] like Figure 3 and Figure 4 As shown, the snap-fit ​​portion 220 is connected to one side edge of the first clearance hole 211, and the snap-fit ​​portion 220 protrudes from the substrate 210 in a direction away from the clamp 300.

[0083] The second snap-fit ​​member 400 passes through the first clearance hole 211 and snaps into the snap-fit ​​part 220 and the substrate 210.

[0084] In this embodiment, the locking portions 220 of the two first locking members 200 are arranged opposite to each other. The locking portion 220 is connected to one side edge of the first clearance hole 211 and protrudes. The protruding direction is relative to the substrate 210 and away from the clamp 300. The locking portion 220 is located above the first clearance hole 211. The second locking member 400 passes through the first clearance hole 211 and abuts against the locking portion 220. The locking portion 220 applies a squeezing force to the second locking member 400, and the second locking member 400 and the first locking member 200 are locked together relatively firmly.

[0085] According to the installation assembly 10 provided in the embodiments of this application, by providing a snap-fit ​​portion 220 on the edge of the first clearance hole 211 of the first snap-fit ​​member 200 that is opposite to the clamp 300 relative to the substrate 210, the second snap-fit ​​member 400 is snapped more securely with the first snap-fit ​​member 200, and the main shaft 20 drives the installation assembly 10 and the photovoltaic module to rotate with good stability.

[0086] In some embodiments, such as Figure 3 As shown, the snap-fit ​​portion 220 may be provided with a first guide surface 221.

[0087] The first guide surface 221 is located on the side of the snap-fit ​​portion 220 facing the first clearance hole 211.

[0088] The first guide surface 221 is inclined in the direction away from the clamp 300 towards the other side close to the first clearance hole 211.

[0089] In this embodiment, the first guide surface 221 is located on the side of the snap-fit ​​portion 220 facing the first clearance hole 211, and extends from one end of the snap-fit ​​portion 220 to the substrate 210. The first guide surface 221 is inclined towards the other side of the first clearance hole 211 in the direction away from the clamp 300. After the second snap-fit ​​member 400 extends into the first clearance hole 211, one end of the second snap-fit ​​member 400 abuts against the first guide surface 221. The second snap-fit ​​member 400 moves along the inclined direction of the first guide surface 221 and is squeezed against the snap-fit ​​portion 220. The snap-fit ​​portion 220 is elastically deformed, and finally the second snap-fit ​​member 400 is snapped against the first snap-fit ​​member 200. The installation is relatively easy and will not be difficult to install correctly because the first connector is located inside the first groove 110. One side of the second snap-fit ​​member 400 abuts against one side of the snap-fit ​​portion 220.

[0090] It should be noted that the first guide surface 221 can be all or part of the side of the snap-fit ​​portion 220 facing the first clearance hole 211.

[0091] The angle between the first guide surface 221 and the horizontal plane can be set according to specific installation requirements, and no specific restrictions are imposed in this embodiment.

[0092] According to the installation component 10 provided in the embodiments of this application, by providing a first guide surface 221 in the snap-fit ​​portion 220, the second snap-fit ​​member 400 is easier to snap into the first snap-fit ​​member 200, and the installation efficiency is higher.

[0093] In some embodiments, such as Figure 3 As shown, the first clearance hole 211 may be provided with a second guide surface 2111.

[0094] The second guide surface 2111 is located on the side opposite to the first clearance hole 211 and the snap-fit ​​part 220. The second guide surface 2111 is inclined towards the snap-fit ​​part 220 in the direction away from the clamp 300.

[0095] In this embodiment, the second guide surface 2111 extends along one side wall of the first clearance hole 211 to the bottom wall of the substrate 210. The second guide surface 2111 is inclined towards the snap-fit ​​part 220 in the direction away from the clamp 300. After the second snap-fit ​​member 400 extends into the first clearance hole 211, one end of the second snap-fit ​​member 400 can abut against the second guide surface 2111. The second snap-fit ​​member 400 moves along the inclined direction of the second guide surface 2111 and is squeezed against the snap-fit ​​part 220. The snap-fit ​​part 220 is elastically deformed, and finally the second snap-fit ​​member 400 is snapped with the first snap-fit ​​member 200. The installation is relatively easy and will not be difficult to install correctly because the first connector is located inside the first groove 110.

[0096] It should be noted that the second guide surface 2111 can be all or part of one sidewall of the first clearance hole 211.

[0097] The angle between the second guide surface 2111 and the horizontal plane can be set according to specific installation requirements, and no specific restrictions are imposed in this embodiment.

[0098] According to the installation component 10 provided in the embodiments of this application, by providing a second guide surface 2111 on one side wall of the first clearance hole 211, the second snap-fit ​​component 400 is easier to snap-fit ​​with the first snap-fit ​​component 200, and the installation efficiency is higher.

[0099] In some embodiments, such as Figure 3 and Figure 6 As shown, the second snap-fit ​​member 400 may have a protrusion 410.

[0100] The protrusion 410 is located at the end of the second latching member 400 away from the clamp 300. The protrusion 410 passes through the first clearance hole 211 and abuts against the substrate 210. The side of the second latching member 400 away from the protrusion 410 abuts against the latching portion 220.

[0101] In this embodiment, the protrusion 410 is located at the end of the second snap-fit ​​member 400 away from the clamp 300. After the protrusion 410 extends into the first clearance hole 211, the second snap-fit ​​member 400 is pressed against the snap-fit ​​part 220. After the snap-fit ​​part 220 is elastically deformed, the second snap-fit ​​member 400 passes through the first clearance hole 211, and the protrusion 410 is snapped against the substrate 210. The side of the second snap-fit ​​member 400 away from the protrusion 410 abuts against the snap-fit ​​part 220. When the main shaft 20 itself is under its own weight and the photovoltaic module is affected by the wind and exerts force on the purlin 100 or clamp 300 of the mounting component 10, the lower part of the protrusion 410 is snapped against the upper surface of the substrate 210, and different sides of the second snap-fit ​​member 400 abut against and press against the snap-fit ​​part 220 and the substrate 210 respectively. The snap-fit ​​is stable and will not easily separate.

[0102] According to the installation component 10 provided in the embodiment of this application, by providing a protrusion 410 at the end of the second snap-fit ​​member 400 away from the clamp 300, it is convenient for the second snap-fit ​​member 400 to be snapped onto the substrate 210 through the protrusion 410 after the second snap-fit ​​member 400 passes through the first clearance hole 211, thus completing the snap-fit ​​between the second snap-fit ​​member 400 and the first snap-fit ​​member 200. The snap-fit ​​is stable and will not easily separate.

[0103] In some embodiments, such as Figure 3 and Figure 6 As shown, the protrusion 410 may be provided with a third guide surface 411.

[0104] The third guide surface 411 is located on the side of the protrusion 410 away from the snap-fit ​​portion 220. The third guide surface 411 is inclined from the end away from the clamp 300 toward the substrate 210 in the direction away from the snap-fit ​​portion 220.

[0105] In this embodiment, the third guide surface 411 is located on the side of the protrusion 410 away from the snap-fit ​​portion 220. The third guide surface 411 is inclined from the end away from the clamp 300 toward the substrate 210 in the direction away from the snap-fit ​​portion 220. After the protrusion 410 extends into the first clearance hole 211, the third guide surface 411 abuts against the substrate 210. The second snap-fit ​​member 400 moves along the inclined direction of the third guide surface 411. After moving a certain distance, the side of the second snap-fit ​​member 400 away from the protrusion 410 abuts against and presses against the snap-fit ​​portion 220. The snap-fit ​​portion 220 is elastically deformed. After the second snap-fit ​​member 400 passes through the first clearance hole 211, the second snap-fit ​​member 400 finally snaps against the first snap-fit ​​member 200. The installation is relatively easy and will not be difficult to install correctly because the first connector is located inside the first groove 110.

[0106] It should be noted that the third guide surface 411 can be all or part of the side wall of the protrusion 410 that is away from the snap-fit ​​part 220.

[0107] The angle between the third guide surface 411 and the horizontal plane can be set according to specific installation requirements, and no specific restrictions are imposed in this embodiment.

[0108] According to the installation component 10 provided in the embodiments of this application, by providing a third guide surface 411 on the protrusion 410, the second snap-fit ​​member 400 is easier to snap-fit ​​with the first snap-fit ​​member 200, and the installation efficiency is higher.

[0109] In some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the mounting component 10 may also include: a reinforcing member 600.

[0110] like Figure 5As shown, the reinforcing member 600 is installed in the first groove 110, the reinforcing member 600 is provided with a receiving groove 610, and the first snap-fit ​​member 200 is installed in the receiving groove 610.

[0111] In this embodiment, the length of the reinforcing member 600 is less than the length of the first groove 110, the two sides of the reinforcing member 600 abut against the inner wall of the first groove 110, the reinforcing member 600 is provided with a receiving groove 610, and the first snap-fit ​​member 200 is installed in the receiving groove 610.

[0112] The first snap-fit ​​connector 200 can be interference-fitted with the receiving groove 610 without installing a connector; the first snap-fit ​​connector 200 can also be fixed to the receiving groove 610 by sealing adhesive; the first snap-fit ​​connector 200 can also be connected to the bottom wall of the receiving groove 610 by bolts or other connectors.

[0113] According to the installation component 10 provided in the embodiments of this application, the strength of the purlin 100 is improved by adding a reinforcing member 600 in the first groove 110, and the positioning and installation of the first snap-fit ​​member 200 is facilitated by providing a receiving groove 610 in the reinforcing member 600.

[0114] In some embodiments, the installation component 10 further includes at least one of the following methods:

[0115] Method 1: For example Figure 3 As shown, the first snap-fit ​​200 is clearance-fitted with the receiving groove 610.

[0116] In this embodiment, the first snap-fit ​​member 200 is clearance-fitted with the receiving groove 610. The first snap-fit ​​member 200 can be connected to the bottom wall of the receiving groove 610 by bolts, the first snap-fit ​​member 200 can be welded to the receiving groove 610, or the first snap-fit ​​member 200 can be directly placed in the receiving groove 610. The second snap-fit ​​member 400 snaps into the first snap-fit ​​member 200. The gravity of the clamp 300 and the main shaft 20 exerts a downward pulling force on the first snap-fit ​​member 200, fixing the first snap-fit ​​member 200 to the receiving groove 610.

[0117] Method 2: The first snap-fit ​​connector 200 and / or the second snap-fit ​​connector 400 are flexible components.

[0118] In this embodiment, the first snap-fit ​​member 200 can be an elastic member made of elastic materials such as plastic, stainless steel or spring steel, and the second snap-fit ​​member 400 can also be an elastic member made of elastic materials such as plastic, stainless steel or spring steel. The materials of the first snap-fit ​​member 200 and the second snap-fit ​​member 400 can be the same or different.

[0119] Method 3: The second snap-fit ​​part 400 and the clamp 300 are bolted together or integrally formed.

[0120] In this embodiment, when the second snap-fit ​​member 400 and the clamp 300 are bolted together, the second snap-fit ​​member 400 is positioned opposite each other at the opening of the clamp 300. The second snap-fit ​​member 400 may have a heat-pressed nut 420 inside, which has threads. The second snap-fit ​​member 400 is bolted to the clamp 300 via the heat-pressed nut 420. Figure 8 As shown, the second snap-fit ​​component 400 and the clamp 300 together form the second pre-assembled assembly.

[0121] The second connector 400 can also be integrally molded with the clamp 300, such as through injection molding.

[0122] Method 4: The first snap-fit ​​component 200 and the reinforcing component 600 are detachably connected.

[0123] In this embodiment, the first snap-fit ​​member 200 and the reinforcing member 600 can be connected by detachable means such as bolt connection, snap-fit, or adhesive bonding, which is easy to disassemble and maintain.

[0124] According to the installation component 10 provided in the embodiments of this application, by setting the first snap-fit ​​200 and the receiving groove 610 with a clearance fit, a certain installation error and processing error of the first snap-fit ​​200 are allowed when installing the first snap-fit ​​200. At the same time, by setting the materials of the first snap-fit ​​200 and the second snap-fit ​​400, the connection method of the second snap-fit ​​400 and the clamp 300, and the connection method of the first snap-fit ​​200 and the reinforcing member 600, the stability of the installation component 10 is improved, and it is easy to disassemble and maintain, and the operation is convenient.

[0125] In some embodiments, such as Figure 3 and Figure 5 As shown, the reinforcing member 600 may be provided with a second clearance hole 620, and the purlin 100 may be provided with a third clearance hole 120.

[0126] The first end edge of the second clearance hole 620 protrudes from the first end edge of the third clearance hole 120 along the length direction of the purlin 100, and the second end edge of the third clearance hole 120 protrudes from the second end edge of the second clearance hole 620 along the length direction of the purlin 100.

[0127] In this embodiment, the second clearance hole 620 of the reinforcing member 600 and the third clearance hole 120 of the purlin 100 are misaligned. The first end of the second clearance hole 620 and the first end of the third clearance hole 120 are on the side opposite to the snap-fit ​​portion 220, and the second end of the second clearance hole 620 and the second end of the third clearance hole 120 are on the same side as the snap-fit ​​portion 220.

[0128] The first edge of the second clearance hole 620 protrudes from the first edge of the third clearance hole 120 along the length of the purlin 100. The second edge of the third clearance hole 120 protrudes from the second edge of the second clearance hole 620 along the length of the purlin 100. After the second snap-fit ​​member 400 passes through the first clearance hole 211 and snaps onto the substrate 210, the edges of the substrate 210 and the second clearance hole 620 on the side opposite to the snap-fit ​​part 220 abut against the second snap-fit ​​member 400. At the same time, the snap-fit ​​part 220 abuts against the second snap-fit ​​member 400. The three abutting surfaces and one snap-fit ​​surface make the snap-fit ​​more stable. At the same time, when the main shaft 20 rotates or the photovoltaic module is affected by strong winds, the second snap-fit ​​member 400 can be well supported and is not easy to loosen or separate.

[0129] According to the installation component 10 provided in the embodiments of this application, by setting the second clearance hole 620 and the third clearance hole 120 to be installed in a staggered manner, the second snap-fit ​​component 400 can be provided with better support, the snap-fit ​​is more stable, and it is not easy to loosen or separate.

[0130] In some embodiments, the purlin 100 forms a first groove 110 extending through both ends of the purlin 100. A reinforcing member 600 is installed in the first groove 110 and forms a second groove 660. The reinforcing member 600 includes a first segment 630, a second segment 640, and a third segment 650 that are sequentially bent and connected. The first segment 630 and the third segment 650 are oppositely disposed and respectively connected to the opposite side walls of the first groove 110. The second segment 640 is supported between the opposite side walls of the first groove 110. A receiving groove 610 is provided in the second segment 640, and a first snap-fit ​​member 200 is installed in the receiving groove 610. Figure 7 As shown, the purlin 100, the reinforcing member 600 and the first snap-fit ​​member 200 form the first pre-assembled assembly.

[0131] The first section 630 and the third section 650 of the reinforcing member 600 can be riveted to the purlin 100, and the photovoltaic module can be directly installed on the upper surface of the purlin 100 by bolts or rivets.

[0132] The first snap-fit ​​member 200 includes a base plate 210 and a snap-fit ​​portion 220. Two first snap-fit ​​members 200 are spaced apart in the first groove 110. The base plate 210 is mounted in the first groove 110. The base plate 210 is provided with a first clearance hole 211. The snap-fit ​​portion 220 is connected to one side edge of the first clearance hole 211, and the snap-fit ​​portion 220 protrudes from the base plate 210 in a direction away from the clamp 300.

[0133] The two first snap-fit ​​members 200 have snap-fit ​​portions 220 disposed opposite to each other. The snap-fit ​​portion 220 is connected to one side edge of the first clearance hole 211 and protrudes. The protrusion direction is relative to the substrate 210 and is away from the clamp 300. The snap-fit ​​portion 220 is located above the first clearance hole 211. The second snap-fit ​​member 400 passes through the first clearance hole 211 and abuts against the snap-fit ​​portion 220. The snap-fit ​​portion 220 applies a squeezing force to the second snap-fit ​​member 400.

[0134] The second clamping member 400 is positioned opposite each other at the opening of the clamp 300. The second clamping member 400 has a heat-pressed nut 420 inside, which is threaded. The second clamping member 400 is bolted to the clamp 300 via the heat-pressed nut 420. Figure 8 As shown, the second snap-fit ​​component 400 and the clamp 300 together form the second pre-assembled assembly.

[0135] The first guide surface 221 is located on the side of the latching portion 220 facing the first clearance hole 211. The first guide surface 221 is inclined towards the other side of the first clearance hole 211 in a direction away from the first clearance hole 211. The second guide surface 2111 is located on the side of the first clearance hole 211 opposite to the latching portion 220. The second guide surface 2111 is inclined towards the latching portion 220 in a direction away from the first clearance hole 211. The third guide surface 411 is located on the side of the protrusion 410 away from the latching portion 220. The third guide surface 411 is inclined towards the latching portion 220 in a direction away from the first clearance hole 211.

[0136] After the second latching member 400 extends into the first clearance hole 211, the end of the second latching member 400 away from the protrusion 410 first abuts against the first guide surface 221. The second latching member 400 moves along the inclined direction of the first guide surface 221. The third guide surface 411 then abuts against the substrate 210 above the second guide surface 2111. At the same time, the protrusion 410 can abut against the second guide surface 2111. The second latching member 400 moves along the inclined direction of the third guide surface 411 and is pressed against the latching part 220. The latching part 220 elastically deforms. The second latching member 400 passes through the first clearance hole 211. Finally, the second latching member 400 is latched against the first latching member 200.

[0137] When the first snap-fit ​​member 200 and the second snap-fit ​​member 400 are snapped together, the clamp 300 and the purlin 100 together form a cavity 500 for accommodating the main shaft 20 of the photovoltaic system 1.

[0138] According to the installation component 10 provided in the embodiments of this application, by setting the clamp 300 and the purlin 100 to be connected by the first snap-fit ​​member 200 and the second snap-fit ​​member 400, the number of components of the photovoltaic system 1 is reduced, the assembly and disassembly are easy, the installation efficiency is high, and the cost is low.
