Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment:

[0039] Please refer to Figures 1 - 10 , the present invention provides a technical solution: an assembled lamp post, including a connecting rod, a photovoltaic panel 2 and a support rod 3. A plurality of connecting rods are assembled into a main lamp post 1. A placement plate 4 is fixedly installed on the outer side of the main lamp post 1, and both the first connection frame 5 and the second connection frame 6 are located above the placement plate 4. The placement plate 4 is used to support the first connection frame 5 and the second connection frame 6, providing a stable installation foundation for them. The support rod 3 is fixedly installed on the side of the second connection frame 6. A connection component is arranged in the first connection frame 5, and the connection component includes a connection post 12. A clamping component is arranged in the second connection frame 6. Insertion posts 8 are movably installed in both the first connection frame 5 and the second connection frame 6. The connection post 12 in the first connection frame 5 enters the second connection frame 6. The clamping component limits the connection post 12 and simultaneously drives the insertion post 8 to be inserted into the main lamp post 1, promoting the mutual connection between the first connection frame 5 and the second connection frame 6, so that the support rod 3 is installed on the main lamp post 1.

[0040] The adjacent sides of the first connecting frame 5 and the second connecting frame 6 are both provided with connecting cavities that match the main lamp post 1. That is, when the first connecting frame 5 and the second connecting frame 6 are connected together, they can be perfectly matched on the outside of the main lamp post 1.

[0041] In this embodiment, a lead screw 11 is movably installed in the first connecting frame 5. A moving plate 16 is threadedly connected to the lead screw 11. The plug post 8 and the connecting post 12 are both fixedly installed on the same side of the moving plate 16. The plug post 8 is located between two adjacent groups of connecting posts 12. The plug posts 8 in the first connecting frame 5 and the second connecting frame 6 both penetrate through the inner walls of the first connecting frame 5 and the second connecting frame 6 and extend into the main lamp post 1, and further into the inner cavity of the main lamp post 1. The inner wall of the main lamp post 1 is provided with a plug through hole that matches the plug post 8. By means of the plug post 8, it is ensured that both the first connecting frame 5 and the second connecting frame 6 can be stably connected to the main lamp post 1.

[0042] In this embodiment, a first fixing frame 13 and a second fixing frame 14 are provided in the second connecting frame 6. The first fixing frame 13 and the second fixing frame 14 are not connected to each other. A first pushing post 15, a second piston plate 25, a second compression spring 26 and a third piston plate 27 are provided in the second fixing frame 14. The first pushing post 15 extends out of the second fixing frame 14 and contacts the connecting post 12. The third piston plate 27 is fixedly connected to the plug post 8. Both the other end of the first pushing post 15 and the third piston plate 27 are fixedly connected to the inner wall of the second fixing frame 14 by the second compression spring 26. When the first pushing post 15 is squeezed by the connecting post 12, both of the two second compression springs 26 will be squeezed. There are two chambers in the second fixing frame 14, and a connecting through hole is provided between the two chambers. When the third piston plate 27 extends out of the second fixing frame 14, it will drive the plug post 8 in the second connecting frame 6 to be connected to the main lamp post 1.

[0043] In this embodiment, a first cavity and a second cavity are provided in the first fixing frame 13. A first channel 18 is provided between the first cavity and the second cavity. A second pushing post 17 and a tension spring are movably installed in the first cavity. One end of the second pushing post 17 penetrates through the inner wall of the first fixing frame 13 and extends outwards, and a first inclined block 19 is fixedly installed at this end. First inclined edges 24 are provided on the adjacent sides of the first inclined block 19 and the connecting post 12. When the connecting post 12 enters the second connecting frame 6, the first inclined block 19 is pushed towards the inner cavity side of the first fixing frame 13 through the first inclined edge 24. The second pushing post 17 moves simultaneously, and the tension spring is squeezed. At the same time, when the second pushing post 17 moves, it will also cause the gas in the first cavity to enter the second cavity through the first channel 18, providing power for the movement of the first piston plate 20 in the second cavity.

[0044] In this embodiment, a first piston plate 20, a third push column 21, and a first compression spring 22 are arranged in the second cavity. The third push column 21 is fixedly connected to the first compression spring 22. The other end of the third push column 21 penetrates through the inner wall of the first fixed frame 13 and extends out of the first fixed frame 13. A second bevel edge is provided on the adjacent side of the first piston plate 20 and the third push column 21, and they are in sliding contact through the second bevel edge. When the gas from the first cavity enters the second cavity, it will push the first piston plate 20. When the first piston plate 20 moves, it will cause the third push column 21 to move through the second bevel edge, and drive the first limit column 23 to be engaged with the connecting column 12.

[0045] A control valve is installed in the second cavity between the first piston plate 20 and the third push column 21. When the first piston plate 20 moves towards the third push column 21, it will first contact this control valve. After two seconds, the control valve will open, and then the first piston plate 20 will contact the third push column 21 and drive the third push column 21 to move. This control valve is to ensure that the first limit column 23 can vertically enter the first limit engaging groove to be engaged with the connecting column 12, avoiding the deviation of the connecting column 12 when it enters the second connecting frame 6.

[0046] In this embodiment, the engaging component includes a first limit column 23. One end of the first limit column 23 is fixedly connected to the third push column 21, and the other end is engaged with the connecting column 12. A first limit engaging groove matching the first limit column 23 is provided on the connecting column 12. When the first limit column 23 is connected to the connecting column 12 through the first limit engaging groove, the connecting column 12 will be fixed by the first limit column 23. In this way, the first connecting frame 5 and the second connecting frame 6 will be fixed on the outer side of the main lamp post 1, and at the same time, the first connecting frame 5 and the second connecting frame 6 will form an integral body.

[0047] In this embodiment, a plug-in board 29 is fixedly installed below the photovoltaic panel 2, and the plug-in board 29 is inserted into the top inner cavity of the main lamp post 1. A third fixed frame 30 is fixedly installed inside the main lamp post 1. An inclined plate 34, a second rotating column 32 are movably installed in the third fixed frame 30, and a third compression spring 35 is fixedly installed. One side of the inclined plate 34 penetrates through the third fixed frame 30 and is fixedly installed with a second limit column 31. A threaded groove is provided on the upper half surface of the second rotating column 32, and a moving block 33 is threadedly connected to the threaded groove part of the second rotating column 32. When the moving block 33 moves upward, it drives the second limit column 31 to extend into the plug-in board 29 to fix the photovoltaic panel 2. The lower half surface of the second rotating column 32 is set as a smooth surface, and at the same time, the lower half part penetrates through the bottom inner wall of the third fixed frame 30 and is fixedly connected to the top of the first gear 9. The other end of the third compression spring 35 is fixedly connected to the side of the second limit column 31 close to the plug-in board 29.

[0048] In this embodiment, a first gear 9 is arranged below the second rotating column 32. The bottom end of the third fixed frame 30 penetrates and is movably installed with a first tooth column 10. The first gear 9 is meshed and connected with the first tooth column 10, and two adjacent first tooth columns 10 are symmetrically distributed about the center of the first gear 9. After the insertion column 8 enters the main lamp post 1, it pushes the first tooth column 10 to drive the first gear 9 to rotate.

[0049] The insertion column 8 is composed of multiple sub-columns and is connected to the main lamp post 1. One of the sub-columns is in the same plane as the first tooth column 10. When the insertion column 8 enters the inner cavity of the main lamp post 1, this sub-column will push the first tooth column 10 to move. When the first tooth column 10 moves, it will drive the first gear 9 to rotate. When the first gear 9 rotates, it will drive the second rotating column 32 to rotate. In this way, when the second rotating column 32 rotates, it will drive the moving block 33 to move upward through the thread groove on its surface. The adjacent side of the moving block 33 and the inclined plate 34 is provided with a third hypotenuse, and the inclined plate 34 is urged to approach the inner wall of the third fixed frame 30 through the hypotenuse, thereby driving the second limiting column 31 to be clamped with the insertion plate 29 to ensure the stability of the photovoltaic panel 2 inside the main lamp post 1.

[0050] In this embodiment, a toggle handle 7 is movably installed in the placing plate 4. The shape of the toggle handle 7 is L-shaped. A second tooth column is fixedly installed on the top side of the longer side of the toggle handle 7. A first rotating column 28 is also arranged in the first connecting frame 5. A bevel gear is fixedly installed on the top of the first rotating column 28 and on the lead screw 11. When the first rotating column 28 rotates, it can drive the lead screw 11 to rotate through the bevel gear. A second gear is fixedly installed at the bottom end of the first rotating column 28, and the second gear is meshed and connected with the second tooth column. A movement groove for the toggle handle 7 is formed in the placing plate 4. The shape of the movement groove is L-shaped. The shorter side of the movement groove faces downward, and the longer side is perpendicular to the main lamp post 1. When the toggle handle 7 moves upward in the movement groove, the second tooth column at the top of the toggle handle 7 will be meshed and connected with the second gear, and then the toggle handle 7 is moved horizontally. The second tooth column will drive the second gear to rotate, thereby driving the first rotating column 28 to rotate, and driving the lead screw 11 to rotate through the cooperation of the bevel gears, completing the installation between the first connecting frame 5 and the second connecting frame 6, and at the same time completing the assembly of the overall lamp post. The toggle handle 7 that has completed the work will move downward and separate from the second gear.

[0051] After the first connecting frame 5 enters the second connecting frame 6 through the connecting column 12, the first connecting frame 5 and the second connecting frame are tightly connected together through the clamping assembly in the second connecting frame 6. At the same time, the photovoltaic panel 2 is also fixed together, making the connection of the overall lamp post more convenient and fast, reducing the installation time of the overall lamp post, and at the same time reducing the number of bolts used in the installation of the overall lamp post.

[0052] An energy-saving street lamp includes an assembled lamp post as described above.

[0053] Working principle of this embodiment: During assembly, multiple connecting rods are assembled into a main lamp pole 1, and the photovoltaic panel 2 is inserted into the top of the main lamp pole 1 through the plug-in board 29. Then, the first connecting frame 5 and the second connecting frame 6 are sleeved on the outside of the main lamp pole 1, and the first connecting frame 5 and the second connecting frame 6 are placed on the placement plate 4. The toggle handle 7 is first moved upward so that the second tooth column at the top of the toggle handle 7 is in meshing contact with the second gear. Then, the toggle handle 7 is moved horizontally. The toggle handle 7 will drive the second gear to rotate through the second tooth column, and the rotating column 28 cooperates with the bevel gear to drive the lead screw 11 to rotate. In this way, when the lead screw 11 rotates, it will first drive the connecting column 12 to enter the second connecting frame 6 through the moving plate 16. At the same time, it drives the plug-in column 8 in the first connecting frame 5 to move. As the connecting column 12 enters the second connecting frame 6, it will contact the first pushing column 15 and drive the first pushing column 15 to be pushed into the second fixed frame 14. When the first pushing column 15 moves in the second fixed frame 14, it will drive the second piston plate 25 to move in the second fixed frame 14. At the same time, when the second piston plate 25 moves, it will push the third piston plate 27 to move. When the third piston plate 27 moves, it will simultaneously drive the plug-in column 8 to extend out of the inner wall of the second connecting frame 6 and connect with the main light pole 1. At the same time, the plug-in column 8 in the first connecting frame 5 is also connected to the main light pole 1 at the same time. In this way, the first connecting frame 5 and the second connecting frame 6 will be tightly connected to the outside of the main light pole 1.

[0054] After the connecting column 12 enters the second connecting frame 6, the connecting column 12 will drive the second push column 17 to move and move into the first fixed frame 13 through the first bevel 24 and the first bevel block 19. When the two second push columns 17 move, the gas in the first cavity will be pushed into the second cavity through the first channel 18, so that the first piston plate 20 in the second cavity moves. With the cooperation of the control valve, the first piston plate 20 moves, and will drive the third push column 21 to move toward the outside of the first fixed frame 13 with the cooperation of the second bevel. At the same time, when the third push column 21 moves, it will drive the first limiting column 23 to connect with the connecting column 12, so as to ensure the stability of the connecting column 12 in the second connecting frame 6, and at the same time ensure the stability of the connection between the first connecting frame 5 and the second connecting frame 6 through the connecting column 12. The first connecting frame 5 and the second connecting frame 6 are integrated and located on the outside of the main lamp pole 1.

[0055] When the plug-in column 8 enters the inner cavity of the main lamp pole 1, it will push the first tooth column 10. When the first tooth column 10 moves, it will drive the first gear 9 to rotate. When the first gear 9 rotates, it will drive the second rotating column 32 to rotate. When the second rotating column 32 rotates, it will drive the moving block 33 to move upward, and push the inclined plate 34 to move toward the inner wall side of the third fixed frame 30 through the third inclined edge. When the inclined plate 34 moves, it will drive the second limiting column 31 to connect with the plug-in board 29, thereby completing the fixation of the photovoltaic panel 2.

[0056] Only certain exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
