[0034] In order to facilitate the installation of the pressing block 3 , the height of the installation groove II22 is greater than the thickness of the pressing block 3 , so that one end of the pressing block 3 can be easily inserted into the installation groove II22 .

[0035] like Figure 1 and Figure 2 As shown, the opening edge of the mounting groove II22 is flush with the side opposite to the opening of the mounting groove I21, and the width of the mounting groove II22 is greater than the width of the mounting groove I21, thereby making the component frame 2 have a good supporting ability.

[0036] like Figure 3 and Figure 4As shown, the utility model also provides a photovoltaic roof, which includes a purlin 4, a photovoltaic panel 1 and a component frame 2, the component frame 2 is installed at both ends of the photovoltaic panel 1, the component frame 2 is installed on the purlin 4, the component frame 2 is the above-mentioned component frame, two symmetrically arranged component frames 2 are installed on the purlin 4, the installation grooves II22 openings on the two component frames 2 are relatively arranged on the same purlin, and a full-length gap a is formed after the two component frames 2 are spaced apart, a pressing block 3 is provided in the gap a, and the two ends of the pressing block 3 are respectively arranged in the corresponding installation grooves II22, the pressing block 3 and the purlin 4 are fixedly connected by a fastening connector 5, and the end of the photovoltaic panel 1 is inserted in the installation groove I21. The pressing block is fixed to the purlin by bolts. The pressing block 3 is located in the middle position of two adjacent component frames 2, and the bolt passes through the through hole of the pressing block 3 and through the gap between the two adjacent component frames 2. The bolt forms a threaded connection with the screw hole of the purlin. After tightening the bolt, the pressing block 3 presses the component frames 2 on both sides thereof, thereby realizing the fixed connection of the two adjacent component frames 2 on the same purlin 4.

[0037] like Figure 5 As shown, in order to enhance the extrusion effect of the pressing block 3 on the upper plane of the installation groove II22, the utility model is provided with a supporting protrusion I31 protruding from the lower end surface at both ends of the pressing block 3, and the lower end surface of the supporting protrusion I31 is in contact with the upper end surface of the installation groove II22.
