Existing photovoltaic panel brackets use channel steel as a support component to install and fix the photovoltaic panels. The pressure block is an important component in the photovoltaic panel bracket, which can be used to fix the channel steel and the photovoltaic panel.

[0003] For example, the Chinese utility model patent with authorization announcement number CN220935099U: A medium pressure block includes a photovoltaic support beam, a photovoltaic panel fixing frame is provided on the top of the photovoltaic support beam, a medium pressure block is provided between the photovoltaic panel fixing frames, an anti-slip structure is provided on the lower surface of the top of both sides of the medium pressure block, and a limiting groove and a through hole are sequentially opened from top to bottom on the bottom of the medium pressure block. A first bolt passes through the inside of both the limiting groove and the through hole. Since the top of the first bolt is engaged with the limiting groove and the end of the second bolt is engaged with the annular groove, the locking ring can be fixed in one position, thus preventing the locking ring from loosening.

[0004] The aforementioned invention patent utilizes the combination of pressure blocks and bolts to achieve the fixed installation of photovoltaic panels. However, bolts are required for fastening, resulting in a large number of tools to carry during installation and making the operation cumbersome. Therefore, there is an urgent need in the field for edge-rolling pressure blocks to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rolled edge clamping block to solve the technical problem that the installation of photovoltaic panels using clamping blocks in the prior art involves a large amount of tools to carry and is cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: the rolled edge pressing block includes a top plate, and vertically downward side plates are fixed at opposite ends of the top plate, and top pressing plates are fixed at opposite ends of the top plate away from the positions of the side plates; rolled edges are fixed to the bottom ends of the two side plates respectively; the two rolled edges have opposite curling directions in the horizontal direction.

[0007] The installation structure of the rolled edge clamping block, photovoltaic panel, and channel steel includes a channel steel for supporting the photovoltaic panel. The channel steel has an installation groove on its side wall. A rolled edge clamping block is used to limit the connection between the photovoltaic panel and the channel steel. The top pressure plate of the rolled edge clamping block cooperates with the channel steel to clamp and fix the frame of the photovoltaic panel.

[0008] As a preferred embodiment, the curling direction of the bottom edge of the side plate is towards the other side plate, forming a curled edge pressing block with two inwardly curled edges.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1, as Figures 1-6 As shown, the rolled edge pressing block 100 includes a top plate 101, with vertically downward side plates 102 fixed at opposite ends of the top plate 101, and top pressing plates 103 fixed at opposite ends of the top plate 101 away from the positions of the side plates 102; rolled edges 105 are fixed to the bottom ends of the two side plates 102 respectively.

[0030] The curled edge 105 at the bottom of the side plate 102 is curled in the direction of the other side plate 102, forming a curled edge pressing block 100 with two inwardly curled edges 105.

[0031] The free end of the rolled edge 105 has an upward curling tendency, and the height of the free end of the rolled edge 105 is higher than the height of the bottom of the inner wall of the rolled edge 105.

[0032] In another embodiment, reinforcing ribs are stamped on both sides of the side plate 102.

[0033] In another embodiment, a reinforcing rib 104 is stamped at the junction of the top plate 101 and the side plate 102.

[0034] In another embodiment, the surface of the top pressure plate 103 is stamped with reinforcing ribs.

[0035] The top pressure plate 103 includes a first extension plate and a second extension plate fixedly connected end to end. The first extension plate is connected and fixed to the top plate 101. The first extension plate is inclined downward relative to the top plate 101, and the second extension plate is inclined upward relative to the first extension plate.

[0036] The angle between the surface of the first extension plate and the surface of the top plate 101 is 13°, and the angle between the surface of the second extension plate and the surface of the first extension plate is 183°.

[0037] The 300mm channel steel has an inner folded edge at the groove opening.

[0038] Operating principle: During assembly, the rolled edge pressing block 100 is pressed downwards through the gap between adjacent photovoltaic panels 200. After the top pressing plate 103 contacts the frame of the photovoltaic panel 200, the pressing continues, causing the top pressing plate 103 to undergo elastic deformation. The pressing continues until the two rolled edges 105 are respectively engaged in two different mounting slots 301. In another embodiment, as shown... Figure 4 As shown, one rolled edge 105 is inserted into the mounting groove 301, and the other rolled edge 105 is engaged with the inner folded edge. The side plate 102 returns to its original deformation, and the top pressure plate 103 produces incomplete springback, thus completing the function of fixing the channel steel 300 and the photovoltaic panel 200. The assembly process is simple and does not require the use of bolts or other parts with complex assembly processes. After the assembly is completed, if the photovoltaic panel 200 and the rolled edge pressure block 100 tend to loosen upwards, the rolled edge 105 can firmly hook into the mounting groove 301, which can simultaneously form vertical and horizontal limits, preventing the photovoltaic panel and the rolled edge pressure block from loosening, and ensuring good installation stability.

[0039] Example 2, as Figure 7 As shown, based on the technical solution of Embodiment 1, the technical solution of forming a rolled edge block 100 with two inwardly folded rolled edges 105 by having the rolled edge 105 curled towards the other side plate 102 is replaced by having the rolled edge 105 curled away from the other side plate 102 by having the rolled edge 105 curled away from the other side plate 102 by forming a rolled edge block 100 with two outwardly folded rolled edges 105. The channel steel 300 has an inwardly folded edge at the groove opening.

[0040] Operating principle: During assembly, the channel steel 300 is installed with the groove facing upwards. The rolled edge pressure block 100 is pressed downwards from the gap between adjacent photovoltaic panels 200. At the same time, the two side plates 102 and the two rolled edges 105 move downwards into the groove of the channel steel. After the top pressure plate 103 contacts the frame of the photovoltaic panel 200, it continues to press down, and the top pressure plate 103 undergoes elastic deformation. It continues to press down until the rolled edge 105 is completely inserted into the channel steel 300, and the top of the rolled edge 105 abuts against the inner surface of the inner folded edge, thus completing the function of fixing the channel steel 300 and the photovoltaic panel 200.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
