[0034] A pressure block support member 1 and a pressure block adjustment member 2, an adjustment portion 3 is arranged on the side of the pressure block support member 1, a plurality of threaded holes 4 arranged in an array are opened on the adjustment portion 3, and an overlapping area is arranged between adjacent threaded holes 4; an adjustment hole 5 is opened on the side of the pressure block adjustment member 2, and an adjustment bolt 6 passes through the adjustment hole 5 and is connected to any one of the threaded holes 4.

[0035] The pressing block support 1 includes a supporting portion 7 and an adjusting portion 3.

The bolt 9 passes through the through hole 8 and is connected to the photovoltaic panel mounting beam. The adjusting portion 3 is connected to one side of the top end of the supporting portion 7. The supporting portion 7 is arranged on the side of the photovoltaic panel frame 21.

[0036] The length of the vertical section of the support portion 7 close to the photovoltaic panel frame 21 is smaller than the length of the vertical section of the support portion 7 away from the photovoltaic panel frame 21 .

[0037] The pressing block adjusting member 2 includes: a connecting portion 10 and a crimping portion 11. The connecting portion 10 is provided with an adjusting hole 5. The connecting portion 10 is arranged outside the adjusting portion 3. The crimping portion 11 is arranged at the top of the connecting portion 10. The crimping portion 11 is crimped above the photovoltaic panel frame 21.

[0038] A bending portion 12 is provided at one end of the crimping portion 11 away from the connecting portion 10 , and the bending portion 12 is inclined downward relative to the crimping portion 11 .

[0039] The bottom end of the crimping portion 11 is connected with an anti-slip rubber pad.

[0040] The diameter of the threaded hole 4 is equal to the center distance of adjacent threaded holes 4 .

[0041] The pressing block support member 1 and the pressing block adjustment member 2 are configured as any one of an aluminum block and a glass fiber polyurethane block.

[0042] A stop washer is provided at the connection of the adjusting bolt 6.

[0043] The working principle of the utility model is:

[0044] The present embodiment provides a photovoltaic pressing block which can be infinitely adjusted. It adopts a modular design and is formed into a photovoltaic pressing block as a whole by connecting a pressing block support member 1 and a pressing block adjusting member 2. When in use, the height of the pressing block adjusting member 2 relative to the pressing block support member 1 is adjusted according to the thickness of the photovoltaic panel frame 21. The pressing block adjusting member 2 is provided with a plurality of threaded holes 4. The pressing block adjusting member 2 is connected to the corresponding threaded holes 4 by adjusting bolts 6, and the photovoltaic pressing block is adjusted to a height adapted to the photovoltaic panel frame 21.

[0045] The multiple threaded holes 4 are tightly connected and the thread design is tight, which can achieve an effect of nearly stepless adjustment.

[0046] The support portion 7 is arranged in an N-shape and the two vertical sections are of unequal lengths. When the support portion 7 is installed on the mounting beam, the weight of the structural member is reduced while ensuring stable installation.

[0047] The crimping portion 11 of the adjusting member 2 is used to limit the photovoltaic panel frame 21 in the vertical direction, and the side surface of the supporting portion 7 is used to limit the photovoltaic panel frame 21 in the horizontal direction.

[0048] A bending portion 12 is disposed at the end of the crimping portion 11 , and the bending portion 12 is buckled on the outside of the photovoltaic panel frame 21 , so that the photovoltaic panel frame 21 is not easy to fall out.

[0049] An anti-skid rubber pad is provided at the bottom of the crimping portion 11 to increase the friction between the crimping portion 11 and the photovoltaic panel frame 21 , thereby improving the installation stability of the photovoltaic panel frame 21 and protecting the photovoltaic panel frame 21 .

[0050] The pressing block support member 1 and the pressing block adjustment member 2 are set to be any one of an aluminum block and a glass fiber polyurethane block. When manufacturing the pressing block, the aluminum profile is pultruded and cut by designing a mold; glass fiber polyurethane material can also be pultruded and cut.

[0051] The specific technical solution for aluminum profile production is:

[0052] Mold making: Make a suitable mold according to the existing design section;

[0053] Extrusion: Place the aluminum round cast bar into the extruder, extrude it through the frame aluminum profile die, and immediately quench it with air cooling to quickly cool it down;

[0054] Straightening: The aluminum profile just extruded is relatively soft and will bend and deform. It is straightened by a straightening machine, and then the head and tail of the material are sawed off and sent to an aging furnace for aging.

[0055] Aging: heating to the preset temperature and keeping warm for the preset time to improve the strength of the aluminum profile;

[0056] Sand blasting: Use the impact of high-speed sand flow to clean and roughen the surface of aluminum profiles;

[0057] Anodizing: Adding aluminum oxide film makes the frame more corrosion-resistant;

[0058] Further processing: cutting and punching into suitable sizes for shipment.

[0059] The specific technical solution for the production of glass fiber polyurethane is:

[0060] Mold making: Make a suitable mold according to the existing design section;

[0061] Mixing: Put the polyurethane synthetic raw materials into the mixer for mixing;

[0062] Extrusion: Put the glass fiber into the extruder, soak it in the synthesized polyurethane and extrude it into shape;

[0063] Spraying: Spray water-based polyurethane on the surface to achieve weather resistance;

[0064] Further processing: cutting and punching into suitable sizes for shipment.

[0065] The beneficial effects of the utility model are:

[0066] The photovoltaic pressing block provided in this embodiment can be infinitely adjusted. Compared with the current conventional frames, it adopts a combined pressing block design and is connected by adjusting bolts, which is convenient for disassembly and reuse. A plurality of threaded holes 4 are provided at the connection. The threaded holes 4 are tightly connected and have overlapping areas. By connecting with the threaded holes 4 at different positions, the photovoltaic pressing block can be adjusted to different use heights to achieve a nearly infinitely adjustable effect, adapt to photovoltaic panel frames 21 of different component versions, improve the application range of the photovoltaic pressing block, and make it more convenient for customers to use.

[0067] like Figure 7 As shown, in one embodiment, a first pin hole 13 is formed at the top of the adjusting portion 3, and a second pin hole 14 is correspondingly formed on the crimping portion 11, and a pin 15 passes through the first pin hole 13 and the second pin hole 14 and extends into the threaded hole 4 of the adjusting portion 3, and the bottom end of the pin 15 contacts the adjusting bolt 6, and a friction pad 16 is connected to the bottom end of the pin 16.

[0068] The working principle and beneficial effects of the above technical solution are:

[0069] After the photovoltaic panel frame 21 is installed by the photovoltaic pressing block, the photovoltaic panel will shake when subjected to external forces such as wind load during use, causing the adjustment bolt 6 of the photovoltaic pressing block to loosen and the pressing block adjustment member 2 to shift. Pin holes are provided on the top of the adjustment portion 3 and the crimping portion 11. During assembly and installation, the pin 15 is passed through the second pin hole 14 and the first pin hole 13 in sequence to position and lock the pressing block support member 1 and the pressing block adjustment member 2 to avoid displacement when subjected to external force vibration. At the same time, the friction pad 16 at the end of the pin 15 abuts against the adjustment bolt 6 to increase the friction with the adjustment bolt 6 and prevent the adjustment bolt 6 from loosening.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
