To secure the strength of the flexible rope 200, the flexible rope 200 is a wire rope, avoiding breakage of the flexible rope 200. However, the connection structure between the wire rope and the frame 100 easily causes the frame 100 of the photovoltaic module to be locally stressed, thereby causing a problem of breakage of the photovoltaic module.

In order to solve the above-mentioned problems, the present embodiment provides a connection structure, as shown in fig. 1 to 4, which includes a fixing body 1, a pressing block 2 and a second fixing member 4, wherein the pressing block 2 is spaced from the fixing body 1 and has an adjustable distance, the frame 100 is located between the pressing block 2 and the fixing body 1 and is clamped and fixed by the pressing block 2 and the fixing body 1, and the second fixing member 4 is configured to fix the flexible rope 200 to the fixing body 1.

In this connection structure, the distance between briquetting 2 and fixed main part 1 is adjustable for briquetting 2 and fixed main part 1 can be fixed with frame 100 centre gripping so that the upper and lower both sides of frame 100 atress simultaneously, realize the dual fixed of frame 100 and connection structure, have improved the load upper limit that photovoltaic module and connection structure can bear greatly, avoid photovoltaic module because of frame 100 local atress, thereby arouse the cracked problem of photovoltaic module.

Since the adjustment hole 13 is a waist-shaped hole, the fixing bolt 31 can move in the adjustment hole 13 along the long axis direction, that is, the fixing body 1 and the frame 100 can move relatively along the radial direction of the flexible rope 200, thereby ensuring that the flexible rope 200 is not bent in the horizontal direction when the flexible rope 200 is fixed.

In some embodiments, the second fixing member 4 is a U-shaped bolt, both ends of the U-shaped bolt are provided with threads, both ends of the U-shaped bolt pass through the fixing body 1 and are in threaded connection with the nut, and the flexible rope 200 passes between the U-shaped bolt and the fixing body 1. The nuts are connected to both ends of the U-shaped bolt, and the size of the space enclosed by the U-shaped bolt and the fixing body 1 can be increased or decreased by rotating the nuts, thereby facilitating the flexible rope 200 to pass through and fix the flexible rope 200.

The adjusting bolt 5 passes through the fixing portion 21 and is in threaded connection with the adjusting nut 6, and the distance between the fixing portion 21 and the fixing main body 1 is smaller than the distance between the pressing portion 23 and the fixing main body 1, so that the shorter adjusting bolt 5 can be selected, the cost is reduced, and the problem that the adjusting bolt 5 is overlong and easy to break is avoided.

It can be appreciated that the connection structure is mostly disposed in the gap between the adjacent two photovoltaic modules' frames 100, and if each frame 100 is separately disposed, the cost is increased, the efficiency is reduced, and the stability is insufficient.

The laminated piece of the photovoltaic module and the top plate 101 are fixed by sealant, if the first limiting portion 24 is too long, the first limiting portion 24 easily contacts the laminated piece, and the laminated piece is broken. As shown in fig. 1, to solve the above problem, the free end of the first stopper 24 is higher than the bottom surface of the top plate 101. The sealant is arranged between the laminated piece and the bottom surface of the top plate 101, so that a certain gap is arranged between the free end of the first limiting part 24 and the laminated piece, so that the laminated piece cannot contact with the first limiting part 24, and the laminated piece is protected from being broken due to contact with the first limiting part 24.
