[0031] The embodiment of the present application discloses a fixing device for a solar photovoltaic panel.

[0032] Reference Figure 1-4 A fixing device for a solar photovoltaic panel comprises a guide rail 1, a placing frame 2 for placing the photovoltaic panel is arranged on the guide rail 1, a side wall of the placing frame 2 is arranged with an abutment groove 21, an upper pressing piece 3 is arranged in the abutment groove 21, a connecting piece 4 is rotatably arranged in the upper pressing piece 3, and a lower pressing piece 5 is rotatably arranged at the lower end of the connecting piece 4;

[0033] The upper pressing member 3 includes an upper pressing plate 31, an upper pressing foot 32 and a limiting frame 33. The limiting frame 33 is fixedly arranged on the upper pressing plate 31, and the two sides of the limiting frame 33 abut against the placement frame 2. The upper pressing foot 32 is respectively extended and arranged on the two sides of the upper pressing plate 31, and the upper pressing foot 32 abuts against the abutting groove 21.

[0034] When in use, the lower pressing piece 5 is inserted into the guide rail 1, and then the placement rack 2 is placed on the guide rail 1, and the placement rack 2 is slid onto the lower pressing piece 5, and the connecting piece 4 is adjusted at the same time to make the upper pressure foot 32 extend into the abutment groove 21, and the tension degree of the connecting piece 4 is adjusted again to make the upper pressing piece 3 and the lower pressing piece 5 fix the placement rack 2, and the placement rack 2 is fixed on the guide rail 1. Through the cooperation of the upper pressing piece 3, the lower pressing piece 5 and the connecting piece 4, the upper pressure foot 32 of the upper pressing piece 3 extends into the placement rack 2 for effective tightening, which can effectively fix the upper pressure foot 32 and the placement rack 2 relative to each other, prevent the upper pressure foot 32 and the placement rack 2 from deviating, so that the overall fixing device and the placement rack 2 can be stably fixed on the guide rail 1.

[0035] Reference Figure 2-3 The bottom of the upper presser foot 32 is also provided with anti-skid corrugations 321. The anti-skid corrugations 321 can effectively enhance the friction between the upper presser foot 32 and the abutting groove 21, making them more stable to each other.

[0036] Reference Figure 2-4 The pressing member 5 includes a connecting block 51, a guide block 52 and an abutment plate 53. The guide block 52 is fixedly arranged on the side wall of the connecting block 51, and the abutment plate 53 is fixedly arranged on the top of the connecting block 51. The placement rack 2 abuts on the abutment plate 53. The guide block 52 is located in the guide rail 1, and the guide block 52 abuts against the guide rail 1. When in use, the connecting block 51 is inserted into the port of the guide rail 1, and the abutment plate 53 is located above the guide rail 1, and the guide block 52 is slidably connected to the inner wall of the guide rail 1.

[0037] Reference Figure 2-4 Limiting plates 531 are provided on both sides of the abutting plate 53, and the limiting plates 531 are inclined near one end of the placement rack 2. When in use, the placement rack 2 can be effectively limited by the setting of the limiting plates 531, so as to better prevent the placement rack 2 from shifting, and at the same time, it can effectively facilitate the positioning of the placement rack 2.

[0038] Reference Figure 3-4 A plurality of latching teeth 521 are provided at the contact point between the guide block 52 and the guide rail 1 , which can effectively enhance the friction between the guide block 52 and the guide rail 1 , and better ensure the relative fixation of the guide rail 1 and the guide block 52 .

[0039] Reference Figure 2-3 The connecting member 4 includes a locking bolt 41 and an anti-slip gasket 42. The locking bolt 41 is rotatably set on the upper pressure plate 31. The anti-slip gasket 42 is located between the locking bolt 41 and the upper pressure plate 31. The other end of the locking bolt 41 is threadedly connected to the lower pressure member 5. When in use, the setting of the anti-slip gasket 42 can effectively ensure that the locking bolt 41 will not rotate after installation, thereby better ensuring the stability of the overall installation.

[0040] More specifically, the top of the locking bolt 41 is provided with a hexagonal hole, which is convenient for workers to install and operate, and facilitates the unification of tools.

[0041] Reference Figure 1-4 , positioning components 6 are also provided on both sides of the top of the limit frame 33, and a positioning column 22 is provided on the top of the placement rack 2. The positioning component 6 includes a positioning plate 61 and a screw 62. One end of the screw 62 is rotatably connected to the positioning plate 61, and the other end of the screw 62 is threadedly connected to the top of the limit frame 33. The two sides of the positioning plate 61 are respectively plugged and matched with the positioning columns 22. When in use, after the upper pressure piece 3 and the lower pressure piece 5 are installed, the two sides of the positioning plate 61 are aligned with the positioning columns 22, and the positioning columns 22 are inserted into the positioning plate 61, and the screw 62 is rotated to fix the positioning plate 61 on the limit frame 33 and the placement rack 2. It can effectively further limit the placement racks 2 on both sides of the positioning frame and prevent the placement racks 2 on both sides of the positioning frame from moving back and forth.

[0042] Reference Figure 1 , Figure 2 , Figure 4 A non-slip pad 23 is also provided at the bottom of the placement rack 2. The setting of the non-slip pad 23 can increase the friction between the placement rack 2 and the abutment plate 53, so that no relative forward and backward sliding will occur during installation, which is convenient for installation. At the same time, it ensures that the placement rack 2 and the abutment plate 53 will not move relative to each other, and effectively reduces the mutual wear between the bottom of the placement rack 2 and the abutment plate 53.

[0043] More specifically, the upper pressure piece 3, the lower pressure piece 5, and the placement rack 2 are all made of 6005-T5 material. The 6005-T5 aluminum alloy material has the advantages of high strength, good corrosion resistance, good machinability, good thermal conductivity, light weight, and environmental sustainability, and can effectively extend the overall service life.

[0044] The implementation principle of a solar photovoltaic panel fixing device of the embodiment of the present application is as follows: the connecting block 51 and the guide block 52 of the lower pressing member 5 are inserted into the guide rail 1, the abutment plate 53 is located on the upper surface of the guide rail 1, and then the locking bolt 41 is adjusted so that the upper pressing member 3 can move up and down, and then the placement frame 2 is placed on the abutment plate 53 and located between the limit plates 531 on the abutment plate 53, and the upper pressure foot 32 is extended into the abutment groove 21 so that the top of the placement frame 2 is abutted against the top two sides of the limit frame 33, and the limit is adjusted. The positioning columns 22 on the placement racks 2 on both sides of the frame 33 are positioned so that the positioning columns 22 on the placement racks 2 on both sides are on the same straight line, align the two sides of the positioning plate 61 with the positioning columns 22, and insert the positioning columns 22 into the positioning plate 61, turn the screws 62 to fix the positioning plate 61 on the limit frame 33 and the placement rack 2, adjust the locking bolts 41 again to make the upper pressure piece 3 and the lower pressure piece 5 approach each other, so that the placement rack 2 is stably fixed on the guide rail 1 under the action of the lower pressure piece 5 and the upper pressure piece 3.

[0045] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
