[0030] Please refer to Figures 1 to 12 As shown, the utility model discloses a swivel connector 100, which is used to connect the swivel driver 200 in the photovoltaic tracking bracket to the top of the driving column 300. The design purpose of the utility model is to improve the structural strength of the swivel connector 100, effectively ensure the bearing capacity of the swivel connector 100, and thus well realize the force transmission effect.

[0031] Please refer to Figure 1 to Figure 2 As shown, the rotary connector 100 of the utility model first includes a first structural member 1. The first structural member 1 includes a horizontal top plate 11 and two vertical side plates 12 formed below the horizontal top plate 11, and the horizontal top plate 11 is connected to the two vertical side plates 12 as a whole. The horizontal top plate 11 is used for positioning connection with the rotary drive 200, and the two vertical side plates 12 are used for positioning connection with the opposite sides of the driving column 300. The "positioning connection" mentioned here includes direct connection and indirect connection. For example: in a specific embodiment of the utility model, the horizontal top plate 11 and the rotary drive 200 can be called a direct positioning connection, and the vertical side plate 12 is not directly connected to the column side plate 302 of the driving column 300, but is transferred through other plates (such as the second structural member 2 described below) and then connected to the column side plate 302 of the driving column 300, which is also called an indirect connection.

[0032] Compared with the split swivel base in the prior art, the swivel connector 100 of the present invention connects the two vertical side plates 12 formed below the horizontal top plate 11 into one piece through the horizontal top plate 11. When the swivel driver 200 on the horizontal top plate 11 rotates, forces in the upper and lower directions will be generated on both sides of the swivel driver 200. In this solution, the forces in the upper and lower directions will be transmitted to the same vertical side plate 12, thereby reducing the overall force on the swivel connector 100 of the present invention, improving the structural strength of the swivel connector 100, and effectively ensuring the bearing capacity of the swivel connector 100, thereby achieving a good force transmission effect. Furthermore, the plate surface of the horizontal top plate 11 and the mounting base of the swivel driver 200 are provided with screw holes, which are used to directly position the swivel driver 200 on the horizontal top plate 11 by passing bolts through the screw holes, without the need for other plates, namely the second structural member 2 described below, to transfer. Therefore, in the specific implementation of the utility model, the horizontal top plate 11 and the rotary driver 200 can be called directly positioned and connected. The horizontal top plate 11 also has a gap 10 in the middle of the plate surface to prevent the rotary connector 100 from interfering with the rotary driver 200.

[0033] Furthermore, the first structural member 1 is provided with a protrusion 13 at the connection position between the horizontal top plate 11 and each of the vertical side plates 12. The protrusion 13 protrudes outward relative to each of the vertical side plates 12 to reserve installation space for the bolts.

[0034] Please continue to refer to Figure 1 to Figure 2 As shown, the rotary connector 100 further includes a second structural member 2. The second structural member 2 includes a main board 21 and two wing plates 22 extending from opposite ends of the main board 21. The main board 21 is used to connect with the driving column 300, and the two wing plates 22 are respectively connected with the two vertical side plates 12 in a one-to-one correspondence. On the one hand, the second structural member 2 assumes the connection function between the rotary connector 100 and the driving column 300, and on the other hand, the second structural member 2 cooperates with the two vertical side plates 12 to form an H-shaped structure, thereby further increasing the structural strength of the first structural member 1.

[0035] For further information, please refer to Figure 2 As shown, there are two second structural members 2. The two wing plates 22 of each second structural member 2 are bent and extended in the same direction from opposite ends of the corresponding main plate 21 to form an opening 20. The two openings 20 can be disposed on opposite sides of the driving column 300 facing each other.

[0036] Please refer to Figure 2As shown, the wing plate 22 and / or the vertical side plate 12 are respectively provided with a plurality of adjustment holes 201 arranged in the up-down direction so as to be able to adjust the relative position between the first structural member 1 and the second structural member 2 in the up-down direction.

[0037] Furthermore, one of the wing plate 22 and the vertical side plate 12 is provided with a long hole 202 extending longitudinally in the left-right direction (the left-right direction is the length direction of the long hole 202), so as to be able to adjust the relative position between the first structural member 1 and the second structural member 2 in the length direction of the long hole 202, and then to be able to adjust the distance between the two second structural members 2. For driving columns 300 of different sizes, the two second structural members 2 in this solution can be normally installed on the driving columns 300, which greatly improves the versatility of the rotary connector 100 and the flexibility of on-site installation.

[0038] In a specific embodiment, the elongated hole 202 that performs the adjustment function in the left-right direction is arranged on the wing plate 22, and the adjustment hole 201 that performs the adjustment function in the up-down direction is arranged on the vertical side plate 12; of course, in other embodiments not shown in the figure, the adjustment hole 201 and the elongated hole 202 can also be swapped, and the dual adjustment function in the up-down direction and the left-right direction can also be realized; even based on the specific needs of the customer, only one of the up-down direction and the left-right direction is adjusted for the relative position, then the adjustment hole 201 and the elongated hole 202 can also be deleted, for example: if the customer does not need to adjust the relative position in the up-down direction, then the multi-row arrangement of the adjustment holes 201 in the up-down direction can be cancelled; if the customer does not need to adjust the relative position in the left-right direction, then the special setting of the elongated hole 202 can be cancelled.

[0039] Furthermore, the main board 21 is provided with a waist-shaped hole 203 extending in the front-to-back direction, so as to be able to adjust the relative position of the first structural member 1 and the second structural member 2 relative to the driving column 300 in the front-to-back direction. The waist-shaped hole 203 can adjust the relative position in the front-to-back direction by utilizing the characteristic that the waist-shaped hole 203 has a certain length in the front-to-back direction, and the waist-shaped hole 203 can also meet the angle adjustment requirements of the swivel connector 100.

[0040] Please refer to Figures 1 to 12As shown, the utility model also relates to a photovoltaic tracking bracket. The photovoltaic tracking bracket of the utility model comprises a driving column 300, a slewing driver 200 and the slewing connector 100 as described above. As mentioned above, the slewing connector 100 connects the slewing driver 200 to the top of the driving column 300, improves the structural strength of the slewing connector 100, effectively ensures the bearing capacity of the slewing connector 100, and thus well realizes the force transmission effect.

[0041] For further information, please refer to Figures 3 to 12 As shown, the horizontal cross section of the driving column 300 is one of an H-type and a C-type.

[0042] Please refer to Figures 3 to 7 As shown, the driving column 300 includes a column web 301 and two column side plates 302 vertically located at opposite ends of the column web 301 and protruding from opposite sides of the column web 301, that is, the horizontal cross section of the driving column 300 is H-shaped. When the horizontal cross section of the driving column 300 is H-shaped, when the rotary driver 200 is connected to the top of the driving column 300 through the rotary connector 100, each main plate 21 of the second structural member 2 is positioned and connected to the column side plate 302 on the corresponding side by fasteners such as bolts.

[0043] Please refer to Figures 8 to 12 As shown, the driving column 300 includes a column web 301 and two column side plates 302 vertically located at opposite ends of the column web 301 but protruding from one side of the column web 301, that is, the horizontal cross section of the driving column 300 is C-shaped. When the horizontal cross section of the driving column 300 is C-shaped, when the rotary driver 200 is connected to the top of the driving column 300 through the rotary connector 100, the main plate 21 of each second structural member 2 is also positioned and connected with the column side plate 302 on the corresponding side through fasteners such as bolts.

[0044] To sum up, the swivel connector 100 in the photovoltaic tracking bracket of the utility model connects the two vertical side plates 12 bent below the horizontal top plate 11 into one through the horizontal top plate 11, thereby improving the structural strength of the swivel connector 100, effectively ensuring the bearing capacity of the swivel connector 100, and thus realizing the force transmission effect well.
