DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] like Figures 1 to 6 As shown, the foldable bracket of the utility model comprises a bottom beam 1, an inclined beam 2 and an inclined support 3;

[0028] The main bodies of the bottom beam 1, the inclined beam 2 and the inclined brace 3 are all "C"-shaped profiles, which can be manufactured using commonly used "C"-shaped steel. The three constitute an integrated bracket 10 that can be folded and unfolded; when the product leaves the factory, the three are integrated into the structure of the integrated bracket 10, which can facilitate on-site installation operations and improve installation efficiency.

[0029] Specifically, Figure 5 As shown, one end of the bottom beam 1 is hinged to one end of the inclined beam 2, and the other end of the inclined beam 2 is hinged to one end of the inclined brace 3; the bottom surfaces of the inclined beam 2 and the inclined brace 3 are profile grooves B and face the bottom beam 1; thus, when folded, the inclined brace 3 is rotated to be in line with the inclined beam 2, and then it can be stacked and buckled on the bottom beam 1 together with the inclined beam 2, so as to reduce the volume of the product and facilitate product packaging and transportation.

[0030] At the same time, in order to meet the angle adjustment requirements of the installation of the solar panel 20, the other end of the bottom beam 1 can be provided with a plurality of bottom beam hinge holes 11 arranged at intervals along the length direction of the bottom beam 1, and four are taken as an example in this embodiment; and the other end of the diagonal brace 3 is provided with a diagonal brace hinge hole 31; thus, when unfolded, the diagonal brace 3 can be rotated to present different angles with the diagonal beam 2, and the diagonal brace hinge hole 31 at the other end of the diagonal brace 3 is aligned with the different bottom beam hinge holes 11 at the other end of the bottom beam 1 for hinged fixation, so that the angle between the diagonal beam 2 supported by the diagonal brace 3 and the bottom beam 1 can be adjusted according to the needs of the site, making the product installation more flexible and better meeting the installation requirements of the solar panel 20 in different environmental conditions in the actual installation scenario.

[0031] like Figures 3 to 5 As shown, in this embodiment, two hinged ears C are respectively protruded from the ends of the hinges of the diagonal brace 3 and the diagonal beam 2, and the two hinged ears C are distributed on both sides of the profile groove B; after the diagonal brace 3 and the diagonal beam 2 are connected to each other, the four hinged ears C are hinged to each other through rivets 4. In this embodiment, the two hinged ears C of the diagonal beam 2 are located between the two hinged ears C of the diagonal brace 3. The protruding hinged ears C can avoid interference between the ends of the diagonal brace 3 and the diagonal beam 2 when they rotate.

[0032] In this embodiment, the hinged ends of the diagonal brace 3 and the diagonal beam 2 and the bottom beam 1 can also be hinged to the side wall of the bottom beam 1 through the hinged ears C using rivets 4. The diagonal brace hinge holes 31 are correspondingly arranged on the two corresponding hinged ears C of the diagonal brace 3.

[0033] The bottom beam 1 is provided with a clearance hole 12 corresponding to the rivets 4 of the stacked oblique beams 2 and the oblique braces 3 to avoid the rivets 4 so that the oblique beams 2 and the oblique braces 3 can be fully buckled on the bottom beam 1.

Specifically, the mounting holes 21 can cooperate with a clamp 30 to fix the solar panel 20; an upwardly protruding solar panel baffle 22 is provided on the top surface of one end of the inclined beam 2 away from the diagonal support 3, so that the solar panel 20 can be supported and prevented from slipping when installed on the inclined inclined beam 2.

[0036] See also Figure 3 A protruding windshield baffle 32 is provided on the top surface of one end of the diagonal brace 3 away from the diagonal beam 2. The windshield baffle 32 is in an inverted "L" shape, and a windshield slot 33 is formed between the diagonal beam 2 and the diagonal beam 2, which is facing the diagonal beam 2. The windshield slot 33 is used to assist in the installation of the windshield 5 described below.

[0037] like Figure 3 and Figure 4 , a rubber pad 6 is provided at the bottom of the bottom beam 1 for buffering support. After the integrated bracket 10 is unfolded and the solar panel 20 is installed, a ballast plate 7 can be installed on the bottom beam 1, and a weight block 8 is installed on the ballast plate 7; the ballast plate 7 and the weight block 8 of this embodiment are located between the hinged ends of the oblique beam 2 and the oblique support 3, which are respectively hinged to the bottom beam 1. The weight block 8 is provided to increase the weight of the integrated bracket 10, increase the fixing effect of the solar panel 20, and play a corresponding role in preventing wind and displacement.

[0038] See also Figure 1 and Figure 2 In this embodiment, a foldable bracket is composed of twenty integrated brackets 10, five in horizontal direction and four in vertical direction, but the present invention is not limited thereto.

[0039] A single solar panel 20 only needs two integrated brackets 10 and one windshield 5 to complete the installation; the two integrated brackets 10 are unfolded and installed to support the two sides of the solar panel 20; and the two ends of the windshield 5 are respectively connected and fixed to the diagonal struts 3 of the two integrated brackets 10. When installing, the windshield 5 can be pre-clamped on the windshield slot 33, and then locked and fixed with the diagonal strut 3.

[0040] More than two solar panels 20 can be installed by three or four integrated brackets 10; each integrated bracket 10 can be arranged horizontally or in a horizontal and vertical array along the length direction perpendicular to the bottom beam 1; the space between two integrated brackets 10 spaced laterally is used to install solar panels 20. As shown in the figure of this embodiment, there are 20 integrated brackets 10 arranged horizontally and vertically, which can install 16 solar panels 20.

[0041] Also, see Figure 6 The adjacent bottom beams 1 of the longitudinally distributed integrated brackets 10 can be connected and fixed by embedded inner connecting members 9 .

[0042] Specifically, the inner connector 9 can also be a "C"-shaped profile, and the profile groove B of the inner connector 9 is provided with an inner retaining edge 91; the side wall at one end of the inner connector 9 is provided with an inner rivet hole 92, and is inserted into the profile groove B of one of the bottom beams 1, and the inner rivet hole 92 is riveted and fixed with the outer rivet hole D set on the side wall of the bottom beam 1; the side wall at the other end of the inner connector 9 is provided with an outwardly protruding block 93, and is inserted into the profile groove B of another bottom beam 1, and the block 93 is snap-fitted with the clamping hole E set on the side wall of the bottom beam 1, thereby conveniently aligning and positioning the two bottom beams 1. At the same time, the inner retaining edge 91 at the other end of the inner connector 9 is provided with a lower rivet hole 94, and the lower rivet hole 94 is used to cooperate with the upper rivet hole F set on the retaining edge 13 of the other bottom beam 1 for riveting and fixing. Finally, both ends of the inner connector 9 are riveted and fixed to the bottom beam 1, which can ensure a stable and reliable connection.

[0043] Thus, the inner connecting member 9 can be used to conveniently and quickly connect and fix the longitudinally adjacent bottom beams 1 in a hidden manner, thereby effectively improving the installation efficiency and installation stability of the overall photovoltaic support.

[0044] The riveting fixation of this embodiment can be carried out by means of pull riveting or the like.
