[0024] like Figure 1-3As shown, a solar panel connection device for a solar street light includes a connecting ring 1 and a support rod 2. The connecting ring 1 includes a first connecting part 4 and a second connecting part 5. The first connecting part 4 and the second connecting part 5 are both semicircular structures. The ends of both ends of the first connecting part 4 are provided with first connecting blocks 6, and the ends of both ends of the second connecting part 5 are provided with second connecting blocks 7. A locking assembly is provided between the first connecting block 6 and the second connecting block 7. The locking assembly includes a locking bolt 12 and a locking nut 13. The locking bolt 12 passes through the first connecting block 6 and the second connecting block 7 and is connected to the locking nut 13 to lock the first connecting block 6 and the second connecting block 7, thereby completing the assembly of the first connecting part 4 and the second connecting block 5.

[0025] A socket 8 is provided on the outside of the connecting ring 1, and a socket hole 9 is provided in the socket 8. The bottom of the support rod 2 is provided in the socket hole 9. The area of ​​the socket hole 9 is larger than the cross-sectional area of ​​the bottom of the support rod 2, and the area of ​​the socket hole 9 is smaller than the cross-sectional area of ​​the top of the support rod 2. The structure of the support rod 2 can be a structure with a small rectangular bottom and a large rectangular top, or a structure with a small circular bottom and a large circular top. In this embodiment, the structure of the support rod 2 is a structure with a small rectangular bottom and a large rectangular top, and the shape of the socket hole 9 is a corresponding square structure. The number of support rods 2 can be set according to demand. In this embodiment, the number of support rods 2 is four, and the tops of the four support rods 2 are all connected to the solar panel 3. After the first connecting portion 4 and the second connecting portion 5 are arranged around the side of the lamp pole 20, the first connecting portion 4 and the second connecting portion 5 are locked using the locking assembly to fix the connecting ring 1 to the lamp pole 20. The support rods 2 around the bottom of the solar panel 3 are inserted into the socket 8 outside the connecting ring 1. Since the area of ​​the socket hole 9 is larger than the cross-sectional area of ​​the bottom of the support rod 2 and smaller than the cross-sectional area of ​​the top of the support rod 2, even if the diameter of the connecting ring 1 is increased, the support rods 2 around the bottom of the solar panel 3 can still be inserted into the socket 8. However, after the support rods 2 are inserted into the socket 8, the height of the support rods 2 will be raised slightly relative to the socket 8. In order to improve the stability of the connection between the support rods 2 and the socket 8, a fastening screw 11 is provided on the side of the socket 8. The fastening screw 11 extends into the socket hole 9 and can fix the support rods 2. Holes can also be punched on the support rods 2 to facilitate screw tightening, further improving the stability.

[0026] Combine Figure 1 and Figure 3An annular rubber pad 10 is provided on the inner side of the connecting ring 1. When connecting to a lamp pole 20 with a smaller diameter, the annular rubber pad 10 is first placed on the lamp pole 20. Then, the first connecting portion 4 and the second connecting portion 5 are placed around the outer side of the annular rubber pad 10 and locked. By utilizing the good elasticity of the annular rubber pad 10, the gap between the connecting ring 1 and the lamp pole 20 with a smaller diameter is filled, and the installation of the connecting ring 1 is completed. In addition, the elasticity of the annular rubber pad 10 can improve the tightness between the connecting ring 1 and the lamp pole 20 through elastic force. Because the diameter of the connecting ring 1 does not change significantly, the support rods 2 around the bottom of the solar panel 3 can also be inserted into the socket 8, completing the connection between the solar panel 3 and the lamp pole 20 with a smaller diameter. This embodiment allows the solar panel 3 to be easily installed on lamp poles 20 of different diameters when it is replaced, thereby making the solar panel 3 more widely applicable when it is replaced. Example 2

[0027] Combine Figure 4-6 This embodiment has the same parts as Example 1. This embodiment is an improvement on the locking assembly. The locking nut 13 includes an integrally formed threaded portion 14 and a smooth portion 15. The interior of the threaded portion 14 is provided with an internal thread 16 that matches the locking bolt 12. The inner side wall of the smooth portion 15 is a smooth surface and a gap 17 is left between the smooth portion 15 and the locking bolt 12. A through-opening groove 18 is opened on the smooth portion 15. The opening groove 18 is connected to the gap 17 and a plastic plug 19 is inserted on one side of the opening groove 18. There are several uniform thread grooves on the external thread of the rod of the locking bolt 12. When the locking bolt 12 passes through the locking nut 13, the open groove 18 will be connected to any thread groove in the external thread on the rod of the locking screw. A plastic insert 19 is provided on one side of the open groove 18. When the plastic insert 19 is inserted from the open groove 18, one side of the plastic insert 19 will enter the thread groove of the external thread and move along the thread groove from the side of the locking bolt 12 close to the open groove 18 to the side of the locking bolt 12 away from the open groove 18, thereby jamming the locking bolt 12 in the locking nut 13 and preventing the locking bolt 12 from moving. The plastic insert 19 is a wire or linear plastic. The diameter of the plastic insert 19 gradually decreases from the head end to the tail end, wherein the tail end is the end initially inserted into the open slot 18, and the head end is the end that is pressed and inserted. The diameter of the plastic insert 19 gradually decreases from the head end to the tail end. Therefore, during the process of inserting into the thread groove of the external thread of the locking bolt 12, it will become tighter and tighter, thereby being clamped in the thread groove. The plastic insert 19 itself will also gradually deform into a spiral shape during the insertion process. This structure will further make the plastic insert 19 less likely to fall off from the thread groove. Only by pulling out the plastic insert 19 can the locking nut 13 be loosened. The locking nut 13 in this embodiment has an anti-loosening effect and can effectively improve the stability of the connection between the first connecting part 4 and the second connecting part 5.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
