[0054] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] Embodiment 1, refer to Figure 1-2 8-9, the pressing block made of spring steel 65 manganese includes a top plate 106, and the bottoms of the two opposite ends of the top plate 106 are respectively integrally formed with a first side plate and a second side plate;

[0056] An upper pressing tongue 202 is integrally formed on the upper part of the side wall of the first side plate away from the second side plate, and an upper pressing tongue 202 is integrally formed on the upper part of the side wall of the second side plate away from the first side plate, and all the upper pressing tongues 202 have the same shape and are arranged at the same height;

[0057] A lower pressing tongue 204 is integrally formed at the lower part of the side wall of the first side plate away from the second side plate, and a lower pressing tongue 204 is integrally formed at the lower part of the side wall of the second side plate away from the first side plate. All the lower pressing tongues 204 have the same shape and are arranged at the same height;

[0058] A lower pressing tongue groove 203 having a larger surface area than the lower pressing tongue 204 is provided in the first side plate near the lower pressing tongue 204; a lower pressing tongue groove 203 having a larger surface area than the lower pressing tongue 204 is provided in the second side plate near the lower pressing tongue 204; the lower pressing tongue 204 can be deformed in the direction of the lower pressing tongue groove 203 and sink into the upper pressing tongue groove 201;

[0059] The top end of the upper pressing tongue 202 is connected to the first side plate or the second side plate, and the angle between the tongue surface of the upper pressing tongue 202 and the horizontal plane is 30 degrees, so that the upper pressing tongue 202 is easily elastically bent by the reaction force of the channel steel 401; the bottom end of the lower pressing tongue 204 is connected to the first side plate or the second side plate, and the angle between the tongue surface of the lower pressing tongue 204 and the horizontal plane is 30 degrees;

[0060] An upper tongue pressing groove 201 larger than the tongue surface area of ​​the upper tongue 202 is opened in the first side plate near the upper tongue 202; an upper tongue pressing groove 201 larger than the tongue surface area of ​​the upper tongue 202 is opened in the second side plate near the upper tongue 202; the opening of the upper tongue pressing groove 201 can reduce costs.

[0061] The distance S1 between the bottom end of the upper pressing tongue 202 and the top end of the lower pressing tongue 204 is less than the sum T1 of the wall thickness of the channel steel 401 and the thickness of the photovoltaic panel frame 403;

[0062] The distance S2 between the top of the upper pressing tongue 202 and the bottom of the lower pressing tongue 204 is greater than the sum T1 of the wall thickness of the channel steel 401 and the thickness of the photovoltaic panel frame 403;

[0063] By adopting the above technical solution, the photovoltaic panel assembly method is as follows: the edges of two adjacent photovoltaic panel frames 403 are placed on the upper surface of the channel steel 401, the pressing block is located between the two photovoltaic panel frames 403, and the channel steel 401 with a slot hole 402 on the top surface is used. When the installation is not completed, the pressing block is located above the channel steel 401 as a whole; the pressing block is pushed into the lower slot hole 402 so that the first side plate and the second side plate both enter the inner part of the slot hole 402; in the process of continuing to push the pressing block downward, because the lower pressing tongue 204 is inclined relative to the top plate 106, the lower pressing tongue 204 will be subjected to the extrusion force from the slot hole 402 in the direction of the inner part of the downward pressing tongue slot 203, and the lower pressing tongue 20 4 produces elastic deformation and is pressed into the interior of the downward pressing tongue groove 203. In this process, the first side wall and the second side wall also produce elastic deformation; the pressing block continues to push downward, and when the upper pressing tongue 202 contacts the upper surface of the photovoltaic panel frame 403, the upper pressing tongue 202 begins to produce elastic deformation; the pressing block continues to push downward, and when the lower pressing tongue 204 is completely out of the range of the slot hole 402, the lower pressing tongue 204, the first side wall, and the second side wall quickly recover their deformation. At this time, the upper pressing tongue 202 cooperates with the lower pressing tongue 204 to tightly clamp the top wall of the channel steel 401 and the photovoltaic panel frame 403 in the middle with elastic potential energy, completing the limited fixation between the photovoltaic panel frame 403 and the channel steel 401.

[0064] The free end of the upper pressing tongue 202 has an upward bending arc; during the installation of the pressing block, the upper pressing tongue 202 is easily deformed upward by force, making the pressing block easier to install.

[0065] Embodiment 2, based on the scheme of embodiment 1, a first dividing groove 105 is provided in the middle of the bottom end of the first side panel, and a first dividing groove 105 is provided in the middle of the bottom end of the second side panel, the first dividing groove 105 divides the first side panel into a first sub-panel 101 and a second sub-panel 102, and the first dividing groove 105 divides the second side panel into a third sub-panel 103 and a fourth sub-panel 104; the first sub-panel 101 and the third sub-panel 103 are located on one side of the first dividing groove 105, and the second sub-panel 102 and the fourth sub-panel 104 are located on the other side of the first dividing groove 105; the provision of the first dividing groove 105 can not only reduce the cost of the pressing block, but also can press the first sub-panel 101 and the third sub-panel 103 into a slot hole 402, and press the second sub-panel 102 and the fourth sub-panel 104 into adjacent slot holes 402 during the process of assembling photovoltaic panels using the pressing block, thereby increasing the force points between the pressing block and the slot hole 402, making the assembly more stable.

[0066] Embodiment 3, based on the solution of embodiment 1, the bottom ends of the first sub-plate 101 and the second sub-plate 102 are respectively integrally formed with bottom pressing tongues 107, the bottom ends of the third sub-plate 103 and the fourth sub-plate 104 are respectively integrally formed with bottom top tongues 108, the free end of the bottom pressing tongue 107 is obliquely downward toward the second side plate, and the free end of the bottom top tongue 108 is obliquely downward toward the first side plate; the height of the first side plate is less than the height of the second side plate, and the bottom end of the bottom pressing tongue 107 is in conflict with the upper surface of the bottom top tongue 108; When the distance between the first side plate 101 and the third sub-plate 103 is reduced or increased by external force, the friction between the bottom end of the bottom pressing tongue 107 and the upper surface of the bottom top tongue 108 increases the rigidity of the entire pressing block, thereby improving the stability of photovoltaic panel assembly; at the same time, the scheme in which the bottom pressing tongue 107 and the bottom top tongue 108 are in conflict with each other can provide a sufficient lateral deformation range for the first side plate and the second side plate, so that when the photovoltaic panel located outdoors is subjected to external force, the components or photovoltaic panel will not be damaged due to lack of buffering, thereby reducing maintenance costs.

[0067] Reference Figure 6 , the sliding distance S3 of the bottom pressing tongue 107 on the upper surface of the bottom top tongue 108 is greater than twice the lateral span distance S4 of the lower pressing tongue 204;

[0068] By adopting the above technical solution, when the pressing block or other components are damaged, the first side panel and the second side panel can be squeezed close to each other, so that the distance between the lower pressing tongue 204 on the first side panel and the lower pressing tongue 204 on the second side panel is reduced, and the pressing block can be smoothly pushed upward from the slot 402 to complete the partial disassembly of the photovoltaic panel or the assembly bracket. The use of an easily disassembled pressing block facilitates the maintenance of the photovoltaic panel or the assembly bracket.

[0069] Embodiment 4, referring to Figure 3 Based on the solution of the first embodiment, a plurality of second dividing grooves 205 are formed at the free end of the lower pressing tongue 204, and the second dividing grooves 205 divide the lower pressing tongue 204 into a plurality of narrow pressing tongues 206;

[0070] By adopting the above technical solution, a plurality of narrow pressing tongues 206 are used to replace the entire lower pressing tongue 204. When the pressing block is pressed into the slot hole 402, the top plate 106 is tilted to the upper surface of the slot steel 401. In this way, the narrow pressing tongues 206 can restore their deformation in turn and get stuck under the slot hole 402, which makes the installation more labor-saving and reduces the difficulty of installation.

[0071] Example 5, refer to Figure 5Based on the scheme of the third embodiment, a plurality of convex strips 301 are fixed on the upper surface of the bottom top tongue 108 in a linear array; the convex strips 301 can increase the sliding resistance of the bottom pressing tongue 107 on the surface of the bottom top tongue 108, thereby increasing the rigidity of the pressing block; the upper surface of the convex strips 301 includes a deformation friction surface 302 close to the first side plate and a rebound friction surface 303 close to the second side plate; the slope of the deformation friction surface 302 is greater than the slope of the rebound friction surface 303, so that within the same distance, the friction resistance encountered by the first side plate and the second side plate when approaching each other is greater than the friction resistance encountered by the first side plate and the second side plate when recovering from deformation, thereby improving the rigidity of the pressing block and ensuring that the pressing block can quickly recover from deformation when the external force is lost.

[0072] Embodiment 6, based on the solution of embodiment 1, refer to Figure 7 , the middle portion of the top plate 106 is bent downward, and the horizontal distance between the top ends of the first side plate and the second side plate is smaller than the horizontal distance between the bottom ends of the first side plate and the second side plate;

[0073] After the photovoltaic panel and the bracket are assembled, as the use time increases, the first side panel and the second side panel are subjected to the lateral thrust from the photovoltaic panel frame 403 for a long time, and the first side panel, the second side panel and the top panel 106 all produce rigid deformation, and the first side panel and the second side panel cannot be tightly attached to the inner wall of the slot hole 402, and the installation firmness of the photovoltaic panel is reduced; using the above technical solution, before the pressing block is put into installation, the horizontal distance between the top end of the first side panel and the second side panel is smaller than the horizontal distance between the bottom end of the first side panel and the second side panel, that is, the bottom end of the first side panel is inclined away from the second side panel; after the pressing block is put into installation, the first side panel and the second side panel are constrained by the slot hole 402, and the bottom distance is reduced. At this time, the top panel 106 is in an elastic deformation state, and the friction between the pressing block and the slot hole 402 is large. The time period from the completion of installation to the inability of the pressing block to be tightly attached to the inner wall of the slot hole 402 can be effectively extended, thereby extending the service life of the pressing block and reducing the maintenance cost of the photovoltaic panel assembly bracket.

[0074] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
