The outer wall of the fixing sleeve 41 is slidably connected with a positioning device 46, and there are two positioning devices 46. The expansion device 4 is fixed on the support rod 2. Functions are added by fixing components on the expansion device 4. The components are fixed by the positioning device 46 before installation. The positioning device 46 only needs to be installed on the expansion device 4 to complete the function installation. The installation of the additional lamp 6 on the positioning device 46 can further increase the lighting range and make the road brighter and clearer. The positioning device 46 is equipped with a warning sign 5 to provide a warning effect, timely reminding people to pay attention to the road conditions or potential dangers ahead, effectively avoiding accidents, and enhancing the road safety factor. In addition, the expansion device 4 can also be combined with other components to achieve multiple functions and effects and improve space utilization.

[0019] The shielding device 45 includes a rotating plate 451, and an elastic ring 452 is fixedly connected to the outer wall of the rotating plate 451. The two sides of the rotating plate 451 rotate with the inner wall of the fixed sleeve 41 through connecting grooves 453, and the connecting grooves 453 are opened in the wall of the rotating plate 451. When adding a component that can only produce an effect after some power is turned on, the elastic ring 452 can be moved to pull the rotating plate 451 open, so that the rotating plate 451 rotates around the cylindrical protrusion on the top, thereby exposing the connecting groove 453 previously blocked by the shielding device 45. The connecting groove 453 is connected to the wire connection port on the support rod 2, which is convenient for the staff to connect the wires. At the same time, when not in use, the shielding device 45 blocks the wire opening on the support rod 2, making it difficult for wind and rain to enter, thereby preventing short circuits in the wires.

[0020] The outer wall of the positioning device 46 includes a positioning block 461, a connecting hole 462 is opened in the wall of the positioning block 461, the outer wall of the positioning block 461 is fixedly connected to the limiting device 464 through a sliding groove 463, and the sliding groove 463 is opened in the wall of the positioning block 461, the inner side wall of the fixing sleeve 41 is fixedly connected to the outer wall of the support rod 2, the outer wall of the fixing sleeve 41 and the outer wall of the connecting plate 42 are both slidably connected to the outer wall of the positioning block 461, and the outer wall of the positioning block 461 away from the bottom of the fixing sleeve 41 is fixedly connected to the outer wall of the mounting lamp 6, The outer wall of the positioning block 461 near the bottom of the fixing sleeve 41 is fixedly connected to the outer wall of the warning sign 5, the limiting device 464 includes a connecting block 4641, the outer wall of the connecting block 4641 is provided with a buffer groove 4642, the outer wall of the connecting block 4641 is fixedly connected with a bending plate 4643, the outer wall of the connecting block 4641 is fixedly connected to the outer wall of the positioning block 461, the limiting device 464 on the positioning block 461 is pushed into the connecting groove 44 of the fixing sleeve 41, and the connecting groove 44 at the upper side is connected to the connecting groove 44 at the lower side. The opening of the slot 44 is relatively large, and the opening of the connecting slot 44 located below is relatively small. When the bent plate 4643 on the connecting block 4641 is pushed into the connecting slot 44 with the larger opening, during this process, the bent plate 4643 is squeezed by the inner walls on both sides of the connecting slot 44, so that the bent plate 4643 squeezes the buffer slot 4642 close to the connecting block 4641 until the sliding slot 463 on the positioning block 461 contacts the outer surface of the fixing sleeve 41. At this time, the positioning block 461 is moved so that the positioning block 461 moves along the surface of the fixing sleeve 41 of the support rod 2. When the connecting After the bottom of block 4641 contacts the inner wall of the bottom of the connecting groove 44, the connecting port opening of the connecting groove 44 is small, which produces a limiting effect on the bending plate 4643, thereby temporarily fixing the positioning device 46. At the same time, the position of the connecting hole 462 on the positioning block 461 corresponds to the positioning threaded hole 43 on the connecting plate 42. Then the staff fixes the positioning block 461 to the connecting plate 42 with bolts, and then fixes the positioning device 46 and the components on the positioning device 46 to the fixing sleeve 41 and the connecting plate 42.

[0021] Working principle:

[0022] When in use, the function of the street light pole is increased by the expansion device 4. Before installing the components, the corresponding components are installed on the positioning device 46. The street light pole consists of a basic lighting street lamp through the base 1, the support rod 2 and the lighting lamp 3. The expansion device 4 is fixed on the support rod 2. The function is increased by fixing the components on the expansion device 4. The components are fixed by the positioning device 46 before installation. The function can be added by simply installing the positioning device 46 on the expansion device 4. Installing the additional lamp 6 on the positioning device 46 can further increase the lighting range, making the road brighter and clearer, and reducing the safety hazards caused by dark corners, whether it is pedestrians or The passage of vehicles at night can be better protected, and the overall travel quality can be improved. The positioning device 46 equipped with a warning sign 5 can provide a warning effect, timely remind people to pay attention to the road conditions or potential dangers ahead, effectively avoid accidents, and enhance the road safety factor. In addition, the expansion device 4 can also be combined with other components to achieve multiple functions and effects, improve space utilization, and have connecting grooves 44 at multiple angles on the fixing sleeve 41. The positioning device 46 temporarily fixed by the connecting groove 44 can be fixed on the connecting groove 44 at different heights and angles according to actual needs, so that the angle of the installed component is optional and the height is optional.

[0023] A positioning device 46 and a shielding device 45 are provided, and the limiting device 464 on the positioning block 461 is pushed into the connecting groove 44 of the fixing sleeve 41. Since the connecting grooves 44 have different widths at the connection opening positions, the connecting grooves 44 located at the top have a larger opening, and the connecting grooves 44 located at the bottom have a smaller opening. When the bent plate 4643 on the connecting block 4641 is pushed into the connecting groove 44 with a larger opening, during this process, the bent plate 4643 is squeezed by the inner walls on both sides of the connecting groove 44, so that the bent plate 4643 squeezes the buffer groove 4642 close to the connecting block 46 41, until the sliding groove 463 on the positioning block 461 contacts the outer surface of the fixing sleeve 41, at this time, the positioning block 461 is moved so that the positioning block 461 moves along the surface of the fixing sleeve 41 of the support rod 2. When the bottom of the connecting block 4641 contacts the inner wall of the bottom of the connecting groove 44, at this time, due to the small opening of the connecting port of the connecting groove 44, a limiting effect is produced on the bending plate 4643, thereby temporarily fixing the positioning device 46. At the same time, the position of the connecting hole 462 on the positioning block 461 corresponds to the positioning threaded hole 43 on the connecting plate 42. Then the staff fixes the positioning block 461 to the connecting plate 42 by bolts, and then fixes the positioning device 46 and the components on the positioning device 46 to the fixing sleeve 41 and the connecting plate 42. The positioning device 46 and the limiting device 464 can prevent the components from accidentally falling during the installation process, avoid damage to the personnel and objects below, ensure construction safety, and also keep the components in a relatively stable position, which is convenient for subsequent precise adjustment and installation, and improves installation efficiency and quality. When the components are completely fixed, the previous temporary fixation can further increase the installation of the components in the expansion device The stability of the device 4 makes it difficult for the component to shake. When adding a component that can only produce an effect after partial power is turned on, the elastic ring 452 can be moved to pull the rotating plate 451 open, so that the rotating plate 451 rotates around the cylindrical protrusion on the top, thereby exposing the connecting groove 453 previously blocked by the shielding device 45. The connecting groove 453 is connected to the wire connection port on the support rod 2, which is convenient for the staff to connect the wires. At the same time, when not in use, the shielding device 45 blocks the wire port on the support rod 2, making it difficult for wind and rain to enter, thereby preventing short circuits in the wires.
