[0041] When the axis of circular arc groove of limiting piece 7 does not coincide with the axis of positioning shaft 2, limiting piece 7 locks the flipping of support shaft 3 around positioning shaft 2;

[0042] The working principle of the device is as follows:

[0043] Unlocking state: rotate the connecting shaft 6, so that the axis of the circular arc groove of the limiting piece 7 coincides with the axis of the positioning shaft 2, the mounting frame 1 can be flipped upward around the positioning shaft 2, the supporting shaft 3 slides along the circular arc groove, until the supporting shaft 3 is completely separated from the limiting piece 7, then the positioning shaft 2 is separated from the positioning mechanism 5, and the photovoltaic panel is removed;

[0045] The mounting frame 1 is independently fixed and provided with the positioning shaft 2 at the bottom of both ends and the supporting shaft 3 at the top of both ends, the axes of which are parallel, providing a stable foundation for the installation and operation of the entire photovoltaic structure, greatly improving the accuracy of installation and use, the support frame 4 adopts a U-shaped structure, the symmetrically arranged positioning mechanism 5 at the bottom cooperates with the positioning shaft 2, allowing the mounting frame 1 to rotate flexibly around the positioning shaft 2, in the photovoltaic panel installation link, this design allows the mounting frame 1 to easily adjust the angle, the two connecting shafts 6 are rotatably installed in the top fixed holes of the inner groove of the support frame 4, and the rotation axes coincide, the limiting piece 7 fixed thereon is provided with limiting holes cooperating with the supporting shaft 3, after the mounting frame 1 is rotated to the position around the positioning shaft 2, the supporting shaft 3 can accurately fall into the limiting hole, realizing the stable connection of the mounting frame 1 and the support frame 4, and ensuring the stability of the entire photovoltaic structure, the circular arc groove on the limiting piece 7 cooperating with the supporting shaft 3 sliding into the limiting hole has the same radius as the axial distance between the supporting shaft 3 and the positioning shaft 2, the ingenious design ensures that the supporting shaft 3 can smoothly slide into the limiting hole along the circular arc groove, avoiding jamming, the locking mechanism 8 installed on the limiting piece 7 can effectively lock the installation angle of the connecting shaft 6 and the support frame 4, preventing the connecting shaft 6 from rotating due to external forces and other factors during use, thereby avoiding the supporting shaft 3 from being separated from the limiting hole, and ensuring that the entire photovoltaic structure remains stable during long-term use, fully meeting the needs of rapid splicing and stable operation of the roof photovoltaic structure.

[0046] As a preferred solution, as shown in Figures 1 to 5 the locking mechanism 8 includes:

[0047] a connecting column 81 is installed on the limiting piece 7, and the other end of the connecting column 81 is provided with a blocking piece 82;

[0048] a moving piece 83 is installed on the connecting column 81, and the moving piece 83 is slidably installed along the length direction of the connecting column 81, the moving piece 83 is provided with a positioning pin 84, the positioning pin 84 is cooperatively inserted and pulled out with the assembly hole reserved on the support frame 4, and the positioning pin 84 is provided with a chamfer at the cooperatively connected end with the assembly hole.

[0050] One end of the connecting column 81 is stably connected with the limiting piece 7, and the other end of the connecting column 81 is provided with the blocking piece 82, which provides a limiting boundary for the sliding of the mobile piece 83, and ensures that the mobile piece 83 always slides in order on the connecting column 81, avoids the mobile piece 83 from being disconnected from the connecting column 81, and maintains the integrity of the locking mechanism 8 structure. The mobile piece 83 is slidably arranged along the length direction of the connecting column 81, the positioning pin 84 arranged on the mobile piece 83 can be precisely inserted into and pulled out of the assembly hole reserved on the support frame 4, and the locking of the installation angle of the connecting shaft 6 and the support frame 4 is realized. When locking is needed, the positioning pin 84 is inserted into the assembly hole to prevent the connecting shaft 6 from rotating, thereby preventing the support shaft 3 from being disconnected from the limiting hole.

The anti-skid structure on the outer wall of the mobile handle 86 effectively increases the friction between the hands of the operator and the mobile handle 86. Even in complex outdoor environments, such as in humid weather or when the operator's hands are sweating, the operator can still stably grasp the mobile handle 86, avoiding operation errors caused by hand slipping during operation, and improving the reliability of the operation.

[0053] As a preferred solution, as shown in Figures 1 to 6 The positioning mechanism 5 comprises:

[0054] The positioning piece 51 is arranged on the support frame 4, and the positioning piece 51 is provided with a positioning hole matched with the positioning shaft 2, and one side of the positioning hole is provided with a slot into which the positioning shaft 2 is inserted;

[0055] The limiting column 52 is coaxially arranged in the positioning hole of the positioning piece 51, and the key groove reserved on the positioning shaft 2 is connected with the limiting column 52;

[0056] When the key groove opening direction coincides with the positioning hole slot direction, the positioning shaft 2 is inserted into or removed from the positioning piece 51;

[0057] When the key groove opening direction does not coincide with the positioning hole slot direction, the positioning shaft 2 is connected and locked with the positioning piece 51, and the positioning shaft 2 rotates freely around the positioning hole of the positioning piece 51;

[0058] The positioning piece 51 mounted on the support frame 4 is provided with a positioning hole matched with the positioning shaft 2, which provides a stable mounting basis for the mounting frame 1. The slot on one side of the positioning hole makes the insertion operation of the positioning shaft 2 more convenient. The construction personnel can easily insert the positioning shaft 2 into the positioning hole without complex alignment operation. The limiting column 52 is coaxially mounted in the positioning hole of the positioning piece 51 and is connected with the key groove reserved on the positioning shaft 2. This connection mode realizes reliable locking of the positioning shaft 2 and the positioning piece 51. When the key groove opening direction coincides with the positioning hole slot direction, the positioning shaft 2 can be smoothly inserted into or removed from the positioning piece 51, which facilitates disassembly and replacement of the mounting frame 1, and meets the needs of later maintenance or upgrading of the roof photovoltaic structure. When the opening directions of the two do not coincide, the positioning shaft 2 is connected and locked with the positioning piece 51, and the positioning shaft 2 can rotate freely around the positioning hole of the positioning piece 51, allowing the mounting frame 1 to rotate flexibly around the positioning shaft 2, which facilitates adjustment of the angle of the mounting frame 1 during photovoltaic panel installation.

[0059] As a preferred solution, as shown in Figures 1 to 6 When the limiting piece 7 locks the support shaft 3, the key groove opening direction does not coincide with the positioning hole slot;

[0060] The stable connection and locking of the positioning shaft 2 and the positioning piece 51 ensures that the mounting frame 1 will not easily displace or loosen due to external force, ensuring that the photovoltaic panel always maintains a stable installation state during long-term use. The mounting frame 1 cannot be moved at will, avoiding wear or loosening of the photovoltaic panel connection part due to shaking or displacement, effectively prolonging the service life of the photovoltaic structure. At the same time, since the positioning shaft 2 is firmly connected with the positioning piece 51, and the support shaft 3 is tightly locked by the limiting piece 7, the entire photovoltaic structure can better resist the influence of natural environmental factors such as strong wind, heavy rain and other bad weather, reducing the risk of damage to the photovoltaic structure due to weather, and ensuring the continuous and stable operation of the photovoltaic power generation system, providing a reliable hardware basis for roof photovoltaic power generation.

[0061] The quick-spliced roof photovoltaic structure of the utility model has a common mechanical installation mode, connection mode or setting mode, as long as it can achieve the beneficial effects.

[0062] The above are only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present application.
