[0018] The present invention is further described below through specific implementation methods.

[0019] like Figure 1 and Figure 2 As shown, a photovoltaic support rail connector of the utility model is used to be inserted into two adjacent photovoltaic support rails 10, including a top wall 6, a bottom wall 5 and two side walls 7, and the two side walls 7 are relatively arranged between the top wall 6 and the bottom wall 5 to enclose a hollow cavity 2, and the cavity 2 is respectively provided with openings at both ends in the length direction. The closed inner cavity can provide sufficient torsional rigidity for the structure.

[0020] like Figure 1 As shown, thickened protrusions 3 are respectively provided in the middle of the inner side surfaces of the two side walls 7. The thickened protrusions 3 are in the shape of long strips and extend along the length direction of the side walls 7 so as to expand the position range of the mounting screws 11 and ensure the thread engagement length.

[0021] like Figure 1As shown, the inner side surfaces of the two side walls 7 are further provided with two ribs 4, each rib 4 extends along the length direction of the side wall 7, the thickened protrusion 3 is located between the two ribs 4, and the protrusion of the two ribs 4 relative to the inner side surface of the side wall 7 is greater than the protrusion of the thickened protrusion 3 relative to the inner side surface of the side wall 7, and the gap between the two ribs 4 is adapted to the diameter of the tail of the screw 11 passing through the thickened protrusion 3 from the outside of the side wall 7 to the inside.

[0022] In this embodiment, the gap between the two ribs 4 is substantially equal to the diameter of the tail of the screw 11, so that the two ribs 4 can contact the screw 11, thereby holding the screw 11 tightly and ensuring sufficient connection strength.

[0023] like Figure 1 As shown, the thickened convex portion 3 has an outwardly convex arc surface, and the arc surface is distributed up and down at both ends in the circumferential direction. The shape of the arc surface is more optimized than other cross-sectional shapes, and the material consumption is less.

[0024] like Figure 1 As shown, a guide groove 9 is provided in the middle of the outer side surface of the two side walls 7. The guide groove 9 is in a long strip shape and extends along the length direction of the side wall 7. The guide groove 9 plays a guiding role in cooperation with the guide rail 10 and also plays a role in reducing material.

[0025] like Figure 1 As shown, the top of the two side walls 7 is an inclined wall body 8, and the spacing between the two side walls 7 at the inclined wall body 8 gradually increases from top to bottom, and the upper end of the inclined wall body 8 supports the top wall 6, and the top wall 6 and the bottom wall 5 are parallel to each other.

[0026] During construction, first, half of the length of the connector 1 is inserted into a guide rail 10 of a photovoltaic support to be connected, and screws 11 are fixed at the designated positions at both ends of the guide rail 10; then, the other end of the connector 1 is inserted into another guide rail 10 to be connected, and screws 11 are fixed at the designated positions at both ends of the guide rail 10, and the connection of the two guide rails 10 is completed. The designated position is located on the thickened protrusion 3 of the connector 1. The guide groove 9 of the connector 1 and the corresponding reinforced protrusion arranged on the inner side of the guide rail are mutually adapted and play a guiding role.

[0027] The connector 1 of the utility model has a cavity 2 that is closed on all sides, which provides sufficient torsional rigidity for the structure. The connector 1 only needs to be inserted into two adjacent photovoltaic support rails 10 and connected to the photovoltaic support rails 10 with screws 11, which is convenient to install. In particular, the connector 1 is provided with the thickened protrusion 3 and two ribs 4, which increase the contact area with the screws 11 and improve the connection strength. The thickened protrusion 3 of the connector has an outwardly convex arc surface, and the shape of the arc surface is more optimized than other cross-sectional shapes, and the amount of material used is less. The connector 1 is integrally inserted into the photovoltaic support rail 10 through the guide groove 9 provided on the connector, and the installation is easy. The cross-sectional structure of the connector is designed according to the matching photovoltaic support rail structure, the top wall 6 and the bottom wall 5 are parallel to each other, and it has a side wall 7 and an inclined wall body 8, with a simple structure and high material utilization.

[0028] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
