DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] Example 1:

[0030] like Figure 1-Figure 5 The self-locking clamp 5 comprises: a first clamp 1 and a second clamp 2 arranged opposite to each other, one end of the first clamp 1 being connected to one end of the second clamp 2 to form a closed end 3, and the other ends of the first clamp 1 and the second clamp 2 being bent inward to form an open clamping end 4; a clamp 5 comprising an open end 501 and a top plate 502 opposite to the open end 501, the clamp 5 being arranged to cover the outside of the first clamp 1 and the outside of the second clamp 2, with the open end 501 clamped on the outside of the clamping end 4, the top plate 502 being provided with a screw hole 503 passing through the top plate 502; and a screw rod 6 passing through the screw hole 503 and being threadedly connected thereto, with one end of the screw rod 6 abutting against the outside of the closed end 3.

[0031] like Figures 1-4As shown, in this embodiment, the self-locking clamp 5 includes a first clamp 1, a second clamp 2, a clamp 5 and a screw 6; wherein, the first clamp 1 and the second clamp 2 are arranged opposite to each other, and the top end of the first clamp 1 is connected to the top end of the second clamp 2 to form a closed end 3, and the bottom end of the first clamp 1 and the bottom end of the second clamp 2 are respectively bent inward to form an open clamping end 4; the clamp 5 includes an open end 501 and a top plate 502 opposite to the open end 501, the clamp 5 is covered on the outside of the first clamp 1 and the outside of the second clamp 2, and the open end 501 is clamped on the outside of the clamping end 4, and a screw hole 503 passing through the top plate 502 is provided on the top plate 502; the screw 6 passes through the screw hole 503 and is threadedly connected to the screw hole 503, and the bottom end of the screw 6 abuts against the outside of the closed end 3. Specifically, when the self-locking clamp 5 is applied to the connection of the color steel tile, the clamping end 4 composed of the first clamp 1 and the second clamp 2 can be clamped on both sides of the connection of the color steel tile to fix the connection of the color steel tile. The bottom ends of the first clamp 1 and the second clamp 2 are bent inward to form a certain bending angle. When the clamping end 4 is clamped at the connection of the color steel tile, the first clamp 1 and the second clamp 2 can be vertically limited by the bent bottom end, thereby strengthening the connection stability of the first clamp 1, the second clamp 2 and the color steel tile connection; and then the clamp 5 is used to fix the connection of the color steel tile. The clamping end 4 composed of the first clip 1 and the second clip 2 applies a lateral pre-tightening force to pre-tighten the first clip 1 and the second clip 2 to prevent them from loosening, and finally a pre-tightening force is applied to the closed end 3 through the screw 6, so that the first clip 1 and the second clip 2 can sink and press against the color steel tile through the pre-tightening force applied by the screw 6 after clamping the color steel tile connection, further strengthening the connection stability of the first clip 1, the second clip 2 and the color steel tile connection. Therefore, the use of the self-locking clamp 5 provided by the utility model can improve the wind-resistant performance of the photovoltaic roof and improve the stability of the roof structure.

[0032] As a further solution, the self-locking clamp 5 also includes a gasket 7 and a bolt 8. The gasket 7 is sleeved on the screw rod 6 and is located on the outside of the top plate 502. The bolt 8 is threadedly connected to the screw rod 6 and abuts against the side of the gasket 7 away from the top plate 502. Specifically, the gasket 7 is arranged on the top side of the top plate 502 and is penetrated by the screw 6, and the gasket 7 is laterally limited by the screw 6. The bolt 8 is sleeved on the screw 6 and threadedly connected to the screw 6 and is arranged on the top side of the gasket 7, which is used to press the bottom plate and play a vertical limiting role on the gasket 7. The bolt 8 is used to press the clamp 5. When the first clamp 1 and the second clamp 2 are respectively clamped on both sides of the connection of the color steel tile and then clamped by the clamp 5, a downward pre-tightening force can be applied to the clamp 5 by the bolt 8, so that the clamp 5 is pressed on the top side of the color steel tile to make the connection between the self-locking clamp 5 and the color steel tile connection tighter and firmer. The gasket 7 can protect the bolt 8 and the top side of the top plate 502 to reduce wear.

[0033] As a further solution, a limiting hole 301 is provided on the outer side of the closed end 3, and one end of the screw rod 6 is disposed in the limiting hole 301 and abuts against the closed end 3. The limiting hole 301 is used to limit and fix the bottom end of the screw rod 6, thereby enhancing the overall connection stability of the self-locking clamp 5.

[0034] In this embodiment, one end of the first clip 1 and one end of the second clip 2 are detachably connected to form the closed end 3. A first semicircular groove 101 is provided on the outer side of one end of the first clip 1, and a second semicircular groove 201 is provided on the outer side of one end of the second clip 2. The first semicircular groove 101 and the second semicircular groove 201 are arranged opposite each other to form the circular limiting hole 301. The first clip 1 and the second clip 2 are detachable, making them easy to separate into individual pieces for packaging and transportation, thereby reducing space occupation.

[0035] As a further solution, a slot 102 is provided at one end of the first clip 1 , and a protrusion 202 is provided at one end of the second clip 2 . The first clip 1 and the second clip 2 are connected by a combination of the slot 102 and the protrusion 202 .

[0036] As a further solution, serrated surfaces 401 are provided on both sides of the clamping end 4. The serrated surfaces 401 can increase the friction between the first and second clamping pieces 1 and 2 and the color steel tile, thereby preventing the first and second clamping pieces 1 and 2 from loosening.

[0037] In this embodiment, the end surface of the screw rod 6 away from the closed end 3 is provided with a hexagonal groove 601. By using an existing hexagonal tool inserted into the hexagonal groove 601, the screw rod 6 can be easily rotated, which saves effort.

The connection between each metal tile 9, after being clamped by the self-locking clamp 5, has strong wind-resistant performance.

[0040] As a further solution, each of the intermediate wave crests 901 is provided with an oblique groove 902 on both sides thereof, and the oblique grooves 902 on both sides of each intermediate wave crest 901 are arranged relatively to each other. The two ends of the clamping end 4 in each of the self-locking clamps 5 are clamped in the oblique grooves 902 on both sides of each intermediate wave crest 901. Specifically, after the clamping end 4 is clamped in the oblique grooves 902, the oblique grooves 902 serve as a vertical limit for the clamping end 4, thereby enhancing the connection stability of the first clip 1, the second clip 2, and the metal tile 9.

[0041] As a further solution, the photovoltaic roof also includes a support frame 10, the bottom end of the support frame 10 is used to connect the purlin (not shown), and the top end of the support frame 10 is arranged on the inner side of the medium wave peak 901 and abuts against the inner side of the medium wave peak 901. The support frame 10 supports the medium wave peak 901.
