[0044] The specific structure of the pressing block 120 of the present application is not limited to Figure 7 As shown, it is also possible to Figure 8 Reference Figure 8 As shown, the pressing block 120 includes two legs 122 disposed opposite to each other. Fig. 9 As shown, the legs 122 abut against the clamp 110 , thereby applying downward pressure to the clamp 110 .

[0045] In some other embodiments, the pressing block 120 may have both a pressing plate and a leg, so that pressure can be applied to the frame and the clamp through the pressing plate and the leg respectively, which helps to improve the connection stability between the photovoltaic module and the purlin.

[0046] Next, the locking member 130 in the pressing block assembly 100 will be described in detail.

The clamp 110 clamps the bottom edge of the frame 210 through the gap S1, and the opening of the gap S1 faces the frame 210, so that the clamp 110 can prevent the frame 210 from moving toward the middle of the laminate 220 on the one hand, and can also prevent the frame 210 from moving upward on the other hand. It should be noted that the use steps of the pressing block assembly of the present application are not limited to the above description. For example, preferably, the fastener 140 is first passed through the pressing block 120 and then connected to the locking member 130 to connect the pressing block 120 and the locking member 130 together, and then the locking member 130 is installed in the purlin 300, so as to prevent the locking member 130 from falling into the purlin 300.

[0049] In one embodiment, reference Figure 1 , Figure 6 and Fig.10 As shown, the width W2 of the locking member 130 is smaller than the width W1 between the two free ends 321 , so that the locking member 130 can be easily placed into the purlin 300 and easily removed from the purlin 300 .

[0050] In another embodiment, the width W2 of the locking member 130 is greater than the width W3 between two adjacent clamping members 110. In this embodiment, the locking member 130 can be installed in the purlin 300 by the following process: avoid the clamping member 110 in the extension direction of the purlin 300, then put the locking member 130 into the purlin 300, and then translate the locking member 130 to the clamping member 110 along the extension direction of the purlin 300.

[0051] refer to Figure 1 As shown, after the photovoltaic assembly 200 is fixed on the purlin 300 , the width of the locking member 130 is smaller than the width W3 between two adjacent clamping members 110 .
