[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 to Figure 3 As shown, an adjustable photovoltaic mounting bracket includes a clamping arm 10 and a mounting base 20 that can be removed and placed with the clamping arm 10. A through hole 201 is provided on the mounting base 20 for a screw 70 to pass through so as to screw the mounting base 20 to the roof beam 40; an assembly plate 15 for mounting a photovoltaic panel guide rail is installed at one end of the clamping arm 10, and a first sliding convex edge 11 and a second sliding convex edge 12 are arranged at intervals at the other end; a mounting boss 21 fixed to the end of the mounting base 20 is provided with a guide groove 211 for a sliding convex edge to slide with; the mounting bracket 100 has a first state and a second state. When the first state is used, the first sliding protrusion 11 is slip-fitted with the guide groove 211, and the clamping arm 10, the second sliding protrusion 12 and the mounting base 20, and the mounting boss 21 enclose a first clamping cavity 101 for clamping tiles 60 and wooden beams 50; when the second state is used, the second sliding protrusion 12 is slip-fitted with the guide groove 211, and the mounting base 20 is screwed and fixed on the roof beam 40, and the clamping arm 10, the first sliding protrusion 11, the mounting boss 21 and the roof beam 40 enclose a second clamping cavity 102 for clamping tiles 60 and wooden beams 50.

[0028] like Figure 2 to Figure 4As shown, a locking threaded hole 212 is provided on the mounting boss 21, a locking hole 13 is provided at the end of the clamping arm 10 and is located between two sliding protrusions, and a locking bolt 30 is passed through the locking hole 13 and is screwed with the locking threaded hole 212 to clamp and install the tile 60 and the wooden beam 50 in the first clamping cavity 101 or the second clamping cavity 102. It should be noted here that since the heights of the tile 60 and the wooden beam 50 are not fixed values ​​during actual construction, the method of screwing and fixing the locking bolt 30 can adapt to fast clamping and installation under different height conditions, greatly improving the installation efficiency.

[0029] The structures of the various components of the utility model are described below.

[0030] like Figure 4 As shown, an adaption groove 14 for the mounting boss 21 to adapt to is formed between the first sliding protrusion 11, the second sliding protrusion 12 and the clamping arm 10. Such a design can improve the stability of the first sliding protrusion 11 or the second sliding protrusion 12 when sliding with the guide groove 211, and facilitate the process of taking and placing the clamping arm 10 and the mounting base 20.

[0031] like Figure 2 to Figure 4 As shown, a window hole 213 is provided on the mounting boss 21, and the axial direction of the window hole 213 is perpendicular to the axial direction of the locking threaded hole 212. An axial hole 214 is provided on the hole wall of the window hole 213, which is aligned with the locking threaded hole 212 and for the locking bolt 30 to pass through. The setting of the window hole 213 can not only facilitate the installer to observe the screwing status of the locking bolt 30, but also enhance the structural strength of the mounting boss 21 and improve the service life of the overall structure.

[0032] like Figure 2 As shown, there is a height difference h between the bottom surface of the mounting boss 21 and the bottom surface of the mounting base 20, so that when the locking bolt 30 is in a tightened state, the screw end of the locking bolt 30 is isolated from the roof beam 40. Such a design not only ensures that the tile 60 and the wooden beam 50 can be stably clamped in the first clamping cavity 101 or the second clamping cavity 102, but also avoids the locking bolt 30 from colliding with the roof beam 40 during the tightening process and causing wear, thereby protecting the roof beam 40.

[0033] like Figure 2 and Figure 3As shown, when the locking bolt 30 is tightened in the locking threaded hole 212, in the first state, there is a clearance gap 103 between the second sliding protrusion 12 and the mounting base 20; in the second state, there is a clearance gap 104 between the first sliding protrusion 11 and the mounting base 20. By setting the clearance gap 103 and the clearance gap 104, it is possible to avoid collision between the sliding protrusion and the mounting base 20 to cause unnecessary wear. It should be noted here that in the first state of the mounting bracket 100, there is no need to punch holes in the roof panel 40, that is, the tile 60 and the wooden beam 50 are directly clamped together by the first clamping cavity 102 to adapt to different installation environments and improve the adaptability of the mounting bracket 100.

[0034] like Figure 5 As shown, an L-shaped plate 80 is detachably mounted on the assembly plate 15. The L-shaped plate 80 has a horizontal portion 81 for mounting a clamp block 812 for mounting a photovoltaic panel guide rail and a vertical portion 82 vertically fixed to the end of the horizontal portion 81. The horizontal portion 81 is provided with a sliding hole 811 for the clamp block 812 to slide with; the vertical portion 82 is fitted with the assembly plate 15 and the fitting surfaces of the two are both provided with anti-slip grooves for increasing friction. The vertical portion 82 is provided with a waist-shaped hole 821, and the sliding plug is inserted into the waist-shaped hole 821. There is an adjusting bolt 90, and an assembly threaded hole 151 for threaded connection of the adjusting bolt 90 is opened on the assembly plate 15; with such a design, when the installed photovoltaic panel guide rail needs to adjust the installation height, the vertical portion 82 is pulled up or pushed down relative to the assembly plate 15 until it is adjusted to the specified height, and then the adjusting bolt 90 inserted in the waist-shaped hole 821 is tightened with the assembly threaded hole 151, and the clamping block 812 for installing the photovoltaic panel guide rail is adjusted to the specified height position, which is convenient for the subsequent installation of the photovoltaic panel guide rail.

[0035] Combination Figure 1 to Figure 7 , the assembly of the utility model is described below.

[0036] When the mounting bracket 100 is used in the first state, the first sliding protrusion 11 is slid into the guide groove 211, so that the clamping arm 10, the second sliding protrusion 12, the mounting base 20 and the mounting boss 21 are enclosed to form a first clamping cavity 101, and the tile 60 and the wooden beam 50 are placed in the first clamping cavity 101, and then the locking bolt 30 is passed through the locking hole 13 and the shaft hole and tightened in the locking threaded hole 212, so that the clamping installation of the tile 60 and the wooden beam 50 is completed;

[0037] When the second state of the mounting bracket 100 is used, the mounting base 20 is first screwed and fixed on the roof beam 40, and then the second sliding protrusion 12 is slid into the guide groove 211. The clamping arm 10, the first sliding protrusion 11, the mounting boss 21 and the roof beam 40 form a second clamping cavity 102. The tile 60 and the wooden beam 50 are placed in the second clamping cavity 102, and then the locking bolt 30 is passed through the locking hole 13 and the shaft hole and tightened in the locking threaded hole 212, thereby completing the clamping installation of the tile 60 and the wooden beam 50.

[0038] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
