[0035] According to the portable C-shaped steel purlin connection structure of the embodiment of the utility model, it comprises: a first purlin 1, a second purlin 2 and a first connecting member 3.

[0036] Specifically, the first purlin 1 defines a first groove 11 along its length direction; the second purlin 2 is slidably connected to the first groove 11, and the second purlin 2 defines a first folded edge 21, a second folded edge 22 and a third folded edge 23 along its length direction, the first folded edge 21 and the third folded edge 23 jointly construct a first connecting portion 24, the second folded edge 22 and the third folded edge 23 define a second groove 26, and the second groove 26 and the first folded edge 21 jointly construct a second connecting portion 25; the first connecting member 3 has a third connecting portion 31 and a fourth connecting portion 32, the third connecting portion 31 is slidably connected to the first connecting portion 24 or the second connecting portion 25, and the fourth connecting portion 32 is suitable for connecting a pressure plate.

[0037] That is to say, the first purlin 1 is provided with a first groove 11, and the second purlin 2 is slidably connected to the first groove 11, so that the second purlin 2 can slide relative to the length direction of the first groove 11, and the second purlin 2 is arranged by the first folded edge 21, the second folded edge 22 and the third folded edge 23 so that the overall supporting strength of the second purlin 2 is improved, and the first connection part 24 formed by the second folded edge 22 and the third folded edge 23 can be slidably connected through the third connection part 31, or the second connection part 25 formed by the first folded edge 21 and the second folded edge 22 can be slidably connected through the third connection part 31 of the first connecting member 3, so that the pressure plate on the fourth connection part 32 can be adjusted horizontally and vertically, so as to match the installation of photovoltaic modules of different specifications.

[0038] Thus, the second purlin 2 is slidably connected to the first groove 11 of the first purlin 1, so that the position of the second purlin 2 along the length direction of the first groove 11 can be adjusted, and the support strength of the second purlin 2 is improved by the folding setting of the second purlin 2. The first connecting member 3 is slidably connected to the first connecting portion 24 or the second connecting portion 25 formed by the folding of the second purlin 2, so that the pressure plate can be adjusted along the length direction of the first connecting portion 24 or the second connecting portion 25, thereby matching the installation of photovoltaic modules of different specifications. The portable C-shaped steel purlin connection structure is simple to install, has high support strength, and is highly versatile.

[0039] For the connection between the first purlin 1 and the second purlin 2, a slidable fastener 4 is provided in the first groove 11, the fastener 4 is connected to the second connecting member 5, and the second connecting member 5 is connected to the second purlin 2; it can be understood that the fastener 4 is slidably arranged in the first groove 11, which can facilitate the second purlin 2 to be fastened by the fastener 4 after the second purlin 2 is adjusted in position, and the second connecting member 5 is arranged to facilitate the connection between the second purlin 2 and the fastener 4, and at the same time improve the connection strength between the first purlin 1 and the second purlin 2. Among them, the second connecting member 5 can be L-shaped, and the fastener 4 can be a square head bolt.

[0040] Further, the second connecting member 5 has a first clearance space, and the first clearance space is suitable for making room for the second folded edge 22 and the third folded edge 23. It can be understood that the second folded edge 22 and the third folded edge 23 can be avoided by the first clearance space, so that the second connecting surface is convenient for fitting the first purlin 1 and the second purlin 2, so that the connection between the second connecting member 5 and the first purlin 1 and the second purlin 2 is better and firmer.

[0041] Further, the second purlin 2 is provided with a plurality of mounting holes 27, which are arranged at intervals along the length direction of the vertical surface of the second purlin 2, and the plurality of mounting holes 27 are suitable for connecting the second connecting member 5. It can be understood that by providing a plurality of mounting holes 27, it is convenient for the second connecting member 5 to be connected to the second purlin 2 through the mounting holes 27, and the plurality of mounting holes 27 are provided to facilitate position adjustment, thereby making the installation of the second purlin 2 easier, wherein the second connecting member 5 can be connected and fixed to the mounting holes 27 by bolts.

[0042] Optionally, the first groove 11 is in an inverted T-shape. It can be understood that the first groove 11 is in an inverted T-shape, so that the first groove 11 limits the head of the fastener 4 from sliding in the first groove 11, so that the connecting end of the fastener 4 extends out of the first groove 11, and then it is convenient to connect with the through hole of the second connecting member 5, wherein the first groove 11 can be integrally formed by bending, which is convenient for saving processing costs.

[0043] In some embodiments, the third connection part 31 has a first abutting end 311 and a second abutting end 312, wherein the first abutting end 311 is suitable for being inserted into the second groove 26, and the second abutting end 312 elastically abuts against the first folded edge 21. It can be understood that by inserting the first abutting end 311 into the second groove 26 and the second abutting end 312 elastically abutting against the first folded edge 21, the third connection part 31 can be clamped on the second connection part 25 and is not easy to fall off, and can be moved along the length direction of the second connection part 25, so as to facilitate the position adjustment of the pressing block on the fourth connection part 32. Among them, the elastic function of the second abutting end 312 can be a hollow setting to form a thin edge, and the end of the second abutting end 312 can be provided with a chamfer.

The angle between the third folded edge 23 and the vertical surface of the second purlin 2 is an acute angle, so that the third connection part 31 can better buckle the third folded edge 23, so that the connection between the first connection member 3 and the second purlin 2 is more secure. Among them, the connection between the third connection part 31 and the third folded edge 23 can be set as a V-shaped hook, and the matching part between the third connection part 31 and the first folded edge 21 can be set as a U-shaped hook.
