DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] Embodiment 1

[0041] like Figures 5 and 6 As shown, the utility model provides a photovoltaic panel assembly fastener, including: a substrate 300, a hook portion 320 and a mounting ear 330, the hook portion 320 is arranged on one side of the substrate 300, the substrate 300 is provided with a mounting groove 310, the mounting ears 330 are symmetrically arranged on the other two sides of the substrate 300, and the mounting ears 330 are provided with a first mounting hole 331.

[0042] In this embodiment, by passing bolts through the first mounting holes 331 on the two mounting ears 330 for fixing, the two mounting ears 330 can hug the mounting beam 110 and reduce shaking, so that the fasteners are firmly fixed on the mounting beam 110.

[0043] In this embodiment, the hook portion 320 is formed by bending one side of the substrate 300, and a U-shaped groove 301 is formed between the hook portion 320 and the substrate 300. The U-shaped groove 301 between the hook portion 320 and the substrate 300 forms an arc transition to avoid stress concentration, so that the hook portion 320 can withstand a larger load and improve the reliability of the device.

[0044] During actual use, the hook portion 320 can hook the upper edge of the back of the photovoltaic panel 200 to prevent the photovoltaic panel from tipping over.

[0045] At the same time, the hook portion 320 can assist in installation. The installation of the traditional photovoltaic panel 200 requires one person to hold the photovoltaic panel 200 and one person to install the lock 120. It is relatively troublesome to install and adjust the level of the photovoltaic panel 200. After using the fastener, when installing the photovoltaic panel 200, the photovoltaic panel 200 can be hung on the hook portion 320 first, and then reinforced with the lock 120. This makes the installation simple and quick, and effectively improves the installation efficiency of the photovoltaic panel 200.

[0046] The base plate 300 has a rectangular outline, and the base plate 300 can be attached to one side of the mounting beam 110. The width of the base plate 300 is controlled to be approximately the same as the width of the mounting beam 110. The mounting groove 310 is opened along the length direction of the base plate 300. In this embodiment, the width of the mounting groove 310 is approximately the same as the opening width of the card slot 111 on the mounting beam 110, so that the lock buckle 120 can pass through the openings of the mounting groove 310 and the card slot 111.

[0047] The mounting ear 330 is an integral structure with the base plate 300. In this embodiment, the mounting ear 330 is an integral structure with the base plate 300, which can simplify the processing process and reduce the steps of welding the mounting ear 330 to the base plate 300. In other embodiments, the mounting ear 330 is mounted on the base plate 300 by welding.

[0048] Embodiment 2

[0049] like Fig.14 As shown, the difference between this embodiment and the first embodiment is that the installation groove 310 passes through the side of the substrate 300 away from the hook portion 320. In this embodiment, the opening at the end of the installation groove 310 faces the end of the mounting beam 110, so that the lock buckle 120 can enter from the opening of the card slot 111 at the end of the mounting beam 110 and move to the position of the installation groove 310.

[0050] Embodiment 3

[0051] like Figures 15 and 16As shown, the difference between this embodiment and the first embodiment is: a photovoltaic panel mounting assembly, including a lock buckle 120, a fixing member 340 and a fastener. The lock buckle 120 includes a pressure block 121, a mounting portion 122 and a fastening bolt 123. A through hole is provided on the pressure block 121, a threaded hole is provided on the top of the mounting portion 122, and the fastening bolt 123 passes through the through hole and is threadedly connected with the threaded hole. The mounting portion 122 is composed of a horizontal plate 1222 and a mounting buckle 1221. The threaded hole is provided on the horizontal plate 1222. The mounting buckles 1221 are symmetrically arranged on both sides of the horizontal plate 1222. The upper sides of the two mounting buckles 1221 are fixedly connected with oppositely arranged protrusions 1223 on the sides close to each other, and the distance between the two protrusions 1223 is less than the diameter of the fastening bolt 123. The distance between the lower parts of the two mounting buckles 1221 is smaller than the distance between the upper parts. A clamping groove 1224 is provided at the junction of the upper and lower parts of the mounting buckle 1221. A wedge-shaped guiding surface 1225 is provided at the lower end of the mounting buckle 1221. The fixing member 340 is used to pass through the first mounting ear 330 on the fastener and fix the fastener.

[0052] In this embodiment, the side of the pressing block 121 is L-shaped. The part of the fastening bolt 123 between the pressing block 121 and the mounting portion 122 is sleeved with a spring 1231, and the fixing member 340 is a bolt and a nut. During use, the lower part of the mounting clip 1221 is passed through the mounting groove 310 and the clamping groove 111. The distance between the upper parts of the two mounting clips 1221 is large and cannot pass through the mounting groove 310. Then, the fastening bolt 123 is tightened to make the fastening bolt 123 pass through the protrusion 1223 between the two mounting clips 1221. Since the distance between the two protrusions 1223 is smaller than the diameter of the fastening bolt 123, the two mounting clips 1221 are stretched open, so that the clamping groove 1224 is clamped at the opening of the mounting groove 310 and the clamping groove 111, thereby completing the fixing of the lock buckle 120. As the fastening bolts 123 are tightened, the distance between the pressing block 121 and the mounting portion 122 is shortened, so that the pressing block 121 is tightly pressed against the photovoltaic panel 200 , thereby effectively fixing the photovoltaic panel 200 .

[0053] Embodiment 4

[0054] like Fig.17 As shown, the difference between this embodiment and the first embodiment is that: a cylindrical guide head 1232 is fixedly connected to the lower end of the fastening bolt 123, the diameter of the guide head 1232 is smaller than the diameter of the fastening bolt 123, the bottom end of the guide head 1232 is provided with a rounded corner or chamfer, and the top of the guide head 1232 is provided with a transition chamfer or rounded corner at the connection between the fastening bolt 123 and the top of the guide head 1232. In this embodiment, the guide head 1232 has a small diameter and can easily and quickly pass through the through hole on the pressing block 121 and the threaded hole of the mounting portion 122, which plays a guiding role in the installation of the fastening bolt 123.

[0055] Embodiment 5

[0056] like Figures 7 to 11 As shown, the difference between this embodiment and the first embodiment is: a photovoltaic panel assembly fastener connection structure, including a bracket 100 and a mounting assembly. The bracket 100 includes a mounting beam 110, a support beam 140 and a cross beam 130, and the mounting beam 110, the support beam 140 and the cross beam 130 form a triangle. The mounting beam 110 is used to install the photovoltaic panel 200. The top of the mounting beam 110 is hinged to one end of the support beam 140, and the other end of the support beam 140 is hinged to one end of the cross beam 130, and the other end of the cross beam 130 is connected to the mounting beam 110. The fastener is installed on the upper part of the mounting beam 110 through a fixing member 340. The mounting beam 110 is provided with a card slot 111 in the extended length direction, and the opening of the card slot 111 close to the fastener gradually decreases. The lower part of the mounting portion 122 of the lock buckle 120 passes through the openings of the mounting slot 310 and the card slot 111 in sequence. After the fastening bolt 123 is locked, the mounting portion 122 is fixedly connected to the card slot 111.

[0057] In this embodiment, during installation, the bolt is passed through the first mounting hole 331 and the second mounting hole, and then fastened with a nut, so that the fastener is firmly fixed on the mounting beam 110. During use, the fastener is pre-installed on the upper end of the mounting beam 110, which can save installation time for on-site installers.

[0058] like Figures 12-13 As shown, in this embodiment, when the mounting beam 110 is provided with a slot 111 and the mounting beam 110 has a large inclination angle, the risk of falling may occur if the edge of the photovoltaic panel 200 is pressed by the lock buckle 120 alone. The fastener is combined with the lock buckle 120 to hang the photovoltaic panel 200, and the lock buckle 120 is used to press the edge, so that the photovoltaic panel 200 is installed more stably and the risk of falling is avoided.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
