As shown in fig. 1 and 3, the buckling-pressing type fastener sequentially comprises a base plate 11 and a pressing plate 21 from bottom to top, wherein hook edges 12 are respectively arranged on the front side and the rear side of the base plate 11;

the upper side surface of the base plate 11 is transversely provided with two vertical plates 13 in parallel, and the bottom surface of the pressing plate 21 is provided with a concave part which can be inserted into the inner spaces of the two vertical plates 13; a fixing mechanism for fixing the concave part is arranged on the vertical plate 13;

as shown in fig. 1, 5 and 6, the left and right sides of the recessed portion are provided with bosses 213 protruding upwards, the fixing mechanism includes two fixing buckles 3, each fixing buckle 3 includes a connecting plate 31, the connecting plate 31 is hinged between two vertical plates 13 through a hinge shaft 33, a free end of the connecting plate 31 is provided with a stopper 32 for buckling the bosses 213, and one end of the stopper 32, which is far away from the connecting plate 31, is provided with a baffle 34 for preventing the stopper 32 from being separated from the bosses 213.

As a specific embodiment, as shown in fig. 1, the substrate 11 is configured as a rectangular structure, the hook edges 12 are disposed on two non-adjacent sides of the upper side of the substrate 11, and the distance between the two hook edges 12 is greater than twice the frame width of the solar panel 4. In this way, the hook edge 12 can hook the support frames of two adjacent solar panels at the same time.

As a specific embodiment, as shown in fig. 4-5, the pressing plate 21 includes two rectangular plates (not shown), the inner sides of the two rectangular plates (the opposite sides of the two rectangular plates are the inner sides) are provided with vertical connecting portions 211 extending downward, the two vertical connecting portions 211 are transitionally connected by a horizontal connecting portion 212, and the vertical connecting portions 211 and the horizontal connecting portion 212 together form a recess portion in a U-shaped structure. The bosses 213 are provided at both left and right sides of the horizontal connection part 212.

Preferably, as shown in fig. 1 and 4, a plurality of rib plates 132 are arranged at the joints of the risers 13 and the base plate 11, a limiting plate 131 is arranged on the outer side of each riser 13 (the side opposite to each other of the two risers 13 is taken as the outer side), and the vertical distance between each limiting plate 131 and the adjacent hook edge 12 is the same as the frame width of the solar panel 4. The purpose of this design is that, firstly, the stability of the riser 13 on the base plate 11 can be enhanced by the rib plate 132, and the riser 13 is strengthened and stabilized; secondly, when hitching the support frame of two adjacent solar energy electroplax through hook limit 12 hook, the medial surface of solar energy electroplax support frame is hitched to hook limit 12 hook, and the lateral surface of support frame can laminate on limiting plate 131, and then makes the frame of solar energy electroplax obtain effectual spacing fixedly, has improved the stability when the solar energy electroplax is connected fixedly.
