Since the frame of the photovoltaic panel 200 usually has two thickness specifications of 30 mm and 35 mm, the existing side pressing assembly 100' has two pressing plates adapted to different thickness specifications. When the existing side pressing assembly 100' faces photovoltaic panels 200 with different frame thicknesses, the bolts need to be disassembled to switch to pressing plates of different lengths, which has the following technical problems:

[0012] Further, the outer surface of the connection part of the long pressing plate and the short pressing plate is an arc surface.

[0013] Further, a spring is assembled between the top of the clamping block and the inner surface of the corner side pressing block, and the bolt passes through the spring.

[0014] Further, the inner surfaces of the long pressing plate and the short pressing plate are formed with wave patterns.

[0015] Further, the inner surface of the long pressing plate is provided with a first limiting plate, and the inner surface of the short pressing plate is formed with a second limiting plate.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0034] Please see Figure 2 As shown, the photovoltaic support includes a photovoltaic panel 200, a guide rail 300, and a common side-pressure component 100. The photovoltaic panel 200 is mounted above the guide rail 300, which supports the photovoltaic panel 200 off the roof. The common side-pressure component 100 presses the frame of the photovoltaic panel 200 onto the guide rail 300 for fixation. The upper part of the guide rail 300 is provided with a slot 301 for fixing with the common side-pressure component 100. The locking block 2 of the common side-pressure component 100 is inserted into the slot 301 to connect the common side-pressure component 100 and the guide rail 300.

[0035] Please see Figures 3-5As shown, the present application provides a shared type side pressing assembly 100 for conveniently fixing photovoltaic panels, which comprises a corner side pressing block 1, a clamping block 2 and a bolt 3; the corner side pressing block 1 comprises a vertically fixedly connected long pressing plate 11 and a short pressing plate 12, the long pressing plate 11 is formed with a first through hole 111, the short pressing plate 12 is formed with a second through hole 121, and the first through hole 111 and the second through hole 121 are communicated to form a strip-shaped hole 13; the top of the clamping block 2 is formed with a threaded hole 20; the bolt 3 passes through the first through hole 111 or the second through hole 121 and then passes through the threaded hole 20 to connect the corner side pressing block 1 and the clamping block 2 together. The corner side pressing block 1 formed by the long pressing plate 11 and the short pressing plate 12 is in L shape and can be applied to photovoltaic panels 200 of different thicknesses. In use, the clamping legs of the clamping block 2 are pressed into the notches of the guide rail 300, the corner side pressing block 1 is tightly attached to the photovoltaic panel 200, and then the bolt 3 is locked to fix the photovoltaic panel 200.

[0036] Reference is made to the accompanying drawings Figure 6 The angle of view is that the short pressing plate 12 is used to press the 35mm-thick photovoltaic panel 200, and the bolt 3 is screwed on the second through hole 121. When the 30mm-thick photovoltaic panel 200 needs to be replaced, the long pressing plate 11 is used to press the photovoltaic panel 200, and the shared type side pressing assembly 100 is adjusted as follows:

[0037] Step 1: loosen the bolt 3 upward, the corner side pressing block 1 rises, and the photovoltaic panel 200 is taken out;

[0038] Step 2: after the corner side pressing block 1 is horizontally rotated by 180°, the corner side pressing block 1 is further rotated clockwise by 90°, the bolt 3 slides along the strip-shaped hole 13 from the second through hole 121 to the first through hole 111, and at this time the long pressing plate 11 faces upward;

[0039] Step 3: put in the 30mm-thick photovoltaic panel 200, screw down the bolt 3, make the long pressing plate 11 press the photovoltaic panel 200, and the replacement of the photovoltaic panel 200 is completed.

[0040] The present application has the characteristics that the shared type side pressing assembly 100 can be applied to photovoltaic panels 200 of two thickness specifications of 30mm and 35mm; when the photovoltaic panel 200 of different frame thicknesses is adjusted and adapted, the two pressing plates of different lengths are switched by rotating the corner side pressing block 1, the replacement can be realized without disassembling the bolt 3, time and labor are saved, and the convenience is high; and small parts cannot be missed or installed reversely, and the installation efficiency is greatly improved.

[0041] In the present application, the long pressing plate 11 and the short pressing plate 12 are different in length and the same in width, and the width edges of the long pressing plate 11 and the short pressing plate 12 are fixedly connected together.

[0042] In the present application, the first through hole 111 is formed at the center of the long pressing plate 11, the second through hole 121 is formed at the center of the short pressing plate 12, the first through hole 111 and the second through hole 121 are in the same vertical plane, so that the strip-shaped hole 13 is a regular strip-shaped hole 13, which is easy to process; after switching the pressing plate, the bolt 3 remains in the same vertical direction and does not displace.

[0043] In the present application, the outer surface of the long pressing plate 11 is formed with a first limiting groove 112, the two sides of the first limiting groove 112 are respectively formed with a first limiting surface 113 and a second limiting surface 114, and the first through hole 111 is located in the first limiting groove 112; the outer surface of the short pressing plate 12 is formed with a second limiting groove 122, the two sides of the second limiting groove 122 are respectively formed with a third limiting surface 123 and a fourth limiting surface 124, and the second through hole 121 is located in the second limiting groove 122. The design of the first limiting surface 113 and the third limiting surface 123 can prevent the bolt 3 from moving outward; the design of the second limiting surface 114 and the fourth limiting surface 124 can prevent the bolt 3 from moving inward; the design of the first limiting groove 112 and the second limiting groove 122 can provide space for the bolt 3 and the elastic washer 4 and the flat washer 5, and at the same time limit the flat washer 5 to avoid loosening of the bolt 3.

[0044] In the present application, the common type side pressing assembly 100 further comprises an elastic washer 4 and a flat washer 5, which are assembled in the first limiting groove 112 or the second limiting groove 122; when the side pressing is locked, the bolt 3 passes through the first through hole 111 or the second through hole 121, and then passes through the elastic washer 4, the flat washer 5 and the screw hole 20 to connect the corner side pressing block 1 and the clamping block 2 together. By setting the elastic washer 4, the loosening of the bolt 3 is prevented. By setting the flat washer 5, the pressure is dispersed.

[0045] In the present application, the outer surface of the connection between the long pressing plate 11 and the short pressing plate 12 is arc-shaped, which facilitates the smooth sliding of the elastic washer 4 and the flat washer 5 on the outer surface of the corner side pressing block 1 when the corner side pressing block 1 rotates.

[0046] In the present application, referring to the accompanying drawings Figure 5 As shown in the drawings, a spring 6 is assembled between the top of the clamping block 2 and the inner surface of the corner side pressing block 1, and the bolt 3 passes through the spring 6. The force generated by the compression deformation of the spring 6 is used to open the corner side pressing block 1 and the clamping block 2, which has the following advantages during installation:

[0047] 1. Before the bolt 3 is locked, the spring 6 lifts the corner side pressing block 1, which facilitates the insertion of the photovoltaic panel 200 between the corner side pressing block 1 and the guide rail 300, and facilitates the subsequent locking step.

[0048] 2. When the common side pressure assembly 100 is pressed into the guide rail 300, the corner side pressure block 1 is too close to the guide rail 300 under the action of gravity. It is necessary to hold the corner side pressure block 1 by hand to prevent it from interfering with the insertion of the locking block 2 into the guide rail 300. Therefore, the spring 6 can push the corner side pressure block 1 upward to avoid installation interference.

[0049] In this invention, the inner surfaces of the long pressure plate 11 and the short pressure plate 12 are both formed with wavy patterns to increase the friction between the corner side pressure block 1 and the photovoltaic panel 200, ensuring that the corner side pressure block 1 can be tightly attached to the photovoltaic panel 200.

[0050] In this invention, the inner surface of the long pressure plate 11 is provided with a first limiting plate 115, and the inner surface of the short pressure plate 12 is formed with a second limiting plate 125. The first limiting plate 115 and the second limiting plate 125 are stop positions and play a limiting role during installation. The first limiting plate 115 and the second limiting plate 125 are in close contact with the photovoltaic panel 200 during installation.

[0051] In this invention, the bolt 3 is any one of a hexagon socket head cap screw, a hexagon head bolt, or a hexagon socket head cap screw. Preferably, an hexagon socket head cap screw is used in this invention to facilitate tightening and loosening of the bolt 3.

[0052] In this invention, the locking block 2 is a U-shaped locking block, which includes a connecting block 21 and two first locking legs 22 and second locking legs 23 respectively fixed on both sides of the connecting block 21; the screw hole 20 is formed at the center of the connecting block, and the bottom of the first locking legs 22 and the second locking legs 23 have locking grooves 24 and hooks 25 for engaging the guide rail 300; a first abutment 26 is vertically fixed to the inner wall of the first locking leg 22, and a second abutment 27 is vertically fixed to the inner wall of the second locking leg 23, with the first abutment 26 and the second abutment 27 facing each other. The first abutment 26 and the second abutment 27 are used to limit and fix the bottom of the bolt 3.

[0053] In this invention, the corner side pressure block 1 and the locking block 2 are made of aluminum; the spring pad 4 and the flat pad 5 are made of stainless steel.

[0054] In this invention, the corner side pressure block 1 is made by aluminum extrusion process. First, a long strip of aluminum profile is extruded, then it is cut into corner side pressure blocks of the required specifications, and finally, strip holes are processed on the corner side pressure blocks.

[0055] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention.
