Description

Technical Field

[0001] The utility model relates to the technical field of high pole lamps, in particular to a high pole lamp for expressways. Background Art

[0002] High pole lamps generally refer to new lighting devices composed of steel tapered poles over 15 meters and high-power combined lamp stands. It consists of lamp holders, internal lamp electrical appliances, pole bodies and foundation parts. In order to meet the lighting needs, high pole lamps are usually used in highway service areas. However, traditional high pole lamps have a light panel at the top of the pole. Since the light panel has a limited lifespan, once it is damaged, it is very troublesome to repair or replace it, and the risk factor is high.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN219713251U starts a motor to drive the threaded rod to rotate so that the lifting rod can rise or fall. The lifting rod needs to be fixed by the block and the slot in the fixed shaft to prevent the lifting rod from falling. When maintenance is needed, the threaded rod is reversed by the motor to drive the lifting rod to fall. The pressing block drives the pressing spring and the pressing rod to be squeezed. The pressing rod will push the block to make it tilt up and out of the slot. The fixed shaft will prevent the block from deflecting or falling off when it tilts up. When the pressing block is released, the pressing spring will drive the pressing block and the pressing rod to reset, so that the block can be fixed to the slot again.

[0004] However, the device still has some shortcomings: the total height of the high pole lamp is large, and when the lifting rod is fully lowered to the lowest position, the height of the lamp panel is still large, and the staff still needs to use climbing tools to repair or replace it, which is very troublesome.
