[0025] Through the above solution, the clamping plate 3 can fix the tempered glass 1;

[0026] In the present embodiment, preferably, the mounting mechanism comprises a mounting plate 9, a mounting groove 10, a sliding rod 11, a slider 12, a spring 13, a limit block 14, a screw 15, a moving block 16 and a groove 17. A mounting plate 9 is fixedly arranged on one side of the mounting frame 2. Mounting grooves 10 are provided at both ends of the top of the photovoltaic back panel body 4. The mounting plate 9 is movably arranged inside the mounting groove 10. A groove 17 is provided inside the mounting plate 9. A sliding rod 11 is fixedly arranged inside the groove 17. Slide blocks 12 are movably arranged on both ends of the surface of the sliding rod 11 through movable holes. Springs 13 are fixedly arranged near the slider 12 at both ends of the surface of the sliding rod 11. One end of the spring 13 is fixedly connected to the slider 12. A limit block 14 is fixedly arranged on the top of the slider 12. One end of the limit block 14 is movably arranged inside the mounting groove 10 through a movable groove. A screw 15 is movably arranged inside the groove 17 through a rotating shaft. A moving block 16 is movably arranged on one end of the screw 15.

[0027] Through the above solution, the mounting frame 2 is mounted on the photovoltaic backboard body 4;

[0028] In this embodiment, preferably, the transmission mechanism includes a cavity 18, a first bevel gear 19 and a second bevel gear 20. The bottom end of the mounting frame 2 is provided with a cavity 18. The first bevel gear 19 is installed on one side of the rotating shaft where the screw rod 15 is located in the cavity 18. The second bevel gear 20 is installed on one side of the cavity 18. The first bevel gear 19 is meshed with the second bevel gear 20.

[0029] Through the above solution, it is convenient to drive the screw rod 15 to rotate;

[0030] In this embodiment, preferably, the mounting frame 2 is provided with a turning handle 21 on one side of the rotating shaft where the second bevel gear 20 is located;

[0031] Through the above solution, the first bevel gear 19 and the second bevel gear 20 are conveniently driven to rotate by using the turning handle 21;

[0032] In this embodiment, preferably, the limit block 14 and the moving block 16 are both arranged in a trapezoidal shape;

[0033] Through the above solution, the movement of the moving block 16 can provide driving force for the limiting block 14;

[0034] When using a photovoltaic back panel tempered glass fixing structure of the present embodiment, the nut 7 is first turned. Since the clamping plate 3 and the mounting frame 2 are movably connected by a rotating shaft, the clamping plate 3 is opened. When the tempered glass 1 is placed on the mounting frame 2, the clamping plate 3 is then flipped over to make it fit with the tempered glass 1. During this process, the protrusion on the edge of the nut 7 needs to be aligned with the strip groove 5 to ensure that the threaded rod 6 and the nut 7 can pass through the clamping plate 3. Then, the nut 7 is screwed so that the protrusion on it is embedded in the limiting groove 22 in the strip groove 5 to fix the closed clamping plate 3, thereby fixing the tempered glass 1 between the two mounting frames 2. Then, the mounting frame 2 is fixed to the photovoltaic back panel body 4, and the mounting plate 9 is aligned with the inside of the mounting groove 10. By driving the turning handle 21, the turning handle 21 rotates to drive the first bevel gear 19 and the second bevel gear 20. The second bevel gear 20 rotates, and the first bevel gear 19 rotates to drive the screw rod 15 to rotate, so that the moving block 16 squeezes the limit block 14. At this time, the limit block 14 moves to both sides of the mounting groove 10 through the movable groove. When the limit block 14 is stuck, the driving screw rod 15 is stopped to complete the fixation; by driving the turning handle 21, the turning handle 21 rotates to drive the first bevel gear 19 and the second bevel gear 20 to rotate, and the first bevel gear 19 rotates to drive the screw rod 15 to rotate. At this time, the moving block 16 moves. When the moving block 16 leaves the limit block 14, the limit block 14 loses the squeezing force of the moving block 16, and the limit block 14 is retracted into the groove 17 by the resilience of the spring 13. At this time, the mounting plate 9 loses the limit of the limit block 14, and the mounting frame 2 can be disassembled.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
