[0032] In order to facilitate the fixing and connection of the solar photovoltaic cell packaging assembly after the side strip 1 is assembled, as shown in FIG. Figure 7 and Figure 8 As shown, the front and rear ends of the upper end of the other side of the side strip 1 are both provided with a first connection block 2, the front end of the lower end of the other side of the side strip 1 is provided with a second connection block 13, and the rear end of one side of the side strip 1 is provided with a second connection block 13, and the second connection block 13 and the first connection block 2 are both welded and fixed to the outer wall of the side strip 1, and the first connection block 2 and the second connection block 13 fixed by welding can facilitate the connection of a pair of side strips 1 after assembly;

[0033] The first connecting block 2 and the second connecting block 13 are internally recessed with a recessed cavity 12, and the recessed cavity 12 is recessed inside the second extension strip 7 and the second connecting block 13 to facilitate the subsequent penetration and embedding of the second bolt 16, thereby preventing the second bolt 16 from protruding after penetration and affecting the storage and fixation of the side strip 1;

[0034] In addition, a second bolt 16 is provided between the pair of first connection blocks 2 and the pair of second connection blocks 13, and a fixing ring 17 is provided on one side of the outside of the second bolt 16, and the inside of the fixing ring 17 is matched with the external thread of the second bolt 16. After the second bolt 16 passes through the pair of first connection blocks 2 and the pair of second connection blocks 13, the fixing ring 17 rotates outside the second bolt 16 to fit and fix the pair of first connection blocks 2 and the pair of second connection blocks 13. The fixing can be completed by the penetration of the second bolt 16, thereby improving the stability of the connection between the pair of first connection blocks 2 and the pair of second connection blocks 13;

[0038] Example 3

[0039] In order to facilitate the grasping of the assembled side strip 1 and to reduce the overall weight of the side strip 1, a holding groove 14 is provided at the upper end of the side strip 1. The side strip 1 can be grasped conveniently through the recessed holding groove 14, and the weight of the entire side strip 1 can be reduced while being grasped.

After being inserted into the second mounting groove 6, until the center position of the second mounting hole 8 overlaps with the first mounting hole 3, the first bolt 15 is rotated to pass through the first mounting hole 3 and embedded in the second mounting hole 8. The second extension strip 7 can be fixedly embedded through the threaded cooperation between the first bolt 15 and the first mounting hole 3 and the second mounting hole 8. After the two side strips 1 are combined, the second bolt 16 passes through the adjacent overlapping first connecting block 2 and the second connecting block 13 to fix the two combined side strips 1. After the second bolt 16 is embedded in the installation position, the combined side strip 1 can be fixed at the position where the second bolt 16 penetrates.
