Next, the briquette assembly 100 of the present application will be described.

Referring to fig. 2 and 3, a perspective view and a front view of a clamping member in an embodiment are shown. The clamping member 110 includes a clamping portion 111 and a connecting portion 112, the clamping portion 111 has a slit S1, an opening of the slit S1 faces a frame clamped by the slit, and the connecting portion 112 has a recess S2. Referring to fig. 1, the clamping portion 111 clamps the bottom edge of the frame 210 through the slit S1, and the recess S2 is matched with the protrusion of the purline 300, and the bottom edge of the frame 210 is located on the connecting portion 112 and abuts against the top surface of the connecting portion 112.

The clamping member 110 may be embodied as the structure shown in fig. 2 and 3. In the unfolded state, the clamping member 110 includes a transverse plate 113, a first vertical plate 114 and a second vertical plate 115, wherein the upper ends of the first vertical plate 114 and the second vertical plate 115 are connected with the transverse plate 113, and the lower ends of the first vertical plate 114 and the second vertical plate 115 extend downwards away from the transverse plate 113. The end of the transverse plate 113 remote from the recess S2 is folded into a slit S1. The first riser 114, the transverse plate 113 located between the first riser 114 and the second riser 115, and the second riser 115 enclose a recess S2. It is to be understood that the above-described embodiment is one specific structure of the clamping member 110 of the present application, and the specific structure of the clamping member 110 is not limited to the above-described embodiment.

Reference is made to the schematic front view of the clamp in another embodiment shown in fig. 4. Compared with the clamping piece in fig. 3, the anti-slip corrugation is arranged on the inner wall of the recess S2 in fig. 4, and the anti-slip corrugation is attached to the outer wall of the purline 300 as described in connection with fig. 1, so that the friction force between the clamping piece 110 and the purline 300 can be increased by the anti-slip corrugation.

The locking member 130 of the compact assembly 100 will be described in detail. Referring to fig. 1, 6 and 10, when the press block assembly 100 is used to fix the photovoltaic module 200 to the purlin 300, the locker 130 is installed in the purlin 300, and the top surface 131 of the locker 130 abuts against the purlin 300. In one embodiment, the locking member 130 has a bar-shaped recess 132, the bar-shaped recess 132 and the top surface 131 are located on the same side of the locking member 130, the free end 321 of the folded side 320 abuts against the locking member 130, and the free end 321 is embedded in the bar-shaped recess 132. The bar-shaped depressions 132 can improve the connection stability between the locker 130 and the purline 300.

The fasteners 140 in the compact assembly 100 are described in detail below. Referring to fig. 1, 7 and 10, one end of the fastener 140 passes through the first through hole 123 in the pressing block 120 and then is coupled to the locker 130, thereby coupling the pressing block 120 and the locker 130 together.
