Description

Technical Field

[0001] This utility model relates to the field of lamp post arm 30 connection technology, and more specifically, to a lamp post arm connection structure that can be connected by gravity. Background Technology

[0002] Currently, the connection methods between street light poles (10) and light arms are mostly direct welding and separate types. Separate types are further divided into flange connections and clamp connections. Direct welding involves welding the light arm directly to the pole. Flange connections involve welding a flange to both the light pole (10) and the light arm, securing them with multiple bolts. Clamp connections involve welding a flange to the light arm and securing it to the pole with two U-bolts. Direct welding is simpler, but because the light arm is not detachable, it occupies more space during transportation and is more prone to damage. Flange and clamp connections, on the other hand, allow for detachable light arms, effectively saving transportation costs and providing separate packaging for protection. However, these two connection methods suffer from inconsistent styles, unattractive appearance, and inconvenient installation and disassembly. Existing power supply boxes can only measure branch circuit data but cannot shut off corresponding branches as needed, requiring manual shutdown, increasing labor costs, and are susceptible to overheating or water immersion, leading to equipment failure and compromising continuous operation.

[0003] Existing patent CN221444148U discloses a lamp arm connection structure, including: a lamp post 10, a lamp arm, a lamp post 10 connector, and a lamp arm connector; the lamp post 10 connector is welded to the outer wall of the lamp post 10; the lamp arm connector is welded to the lamp arm; the lamp arm connector is installed on the lamp post 10 connector, and the lamp post 10 and the lamp arm are installed together through the lamp post 10 connector and the lamp arm connector. Since the lamp post 10 and the lamp arm are separate, transportation costs can be saved and the lamp arm can be better protected. The lamp post 10 connector and the lamp arm connector adopt a hook-type structure and an integrally formed shape, which makes the style uniform and the appearance beautiful. The lamp post 10 and the lamp arm are fixed with two bolts, which makes the installation and disassembly of the lamp arm more convenient while ensuring that the lamp arm connection is firm and reliable.

[0004] However, in the existing patent, the lamp post 10 and the lamp arm are installed together through the lamp post 10 connector and the lamp arm connector. The lamp post 10 and the lamp arm are easy to misalign and require constant adjustment before the screws can be tightened. Utility Model Content

[0005] The purpose of this utility model is to propose a lamp post arm connection structure that can be connected by gravity, including a lamp post 10 and a lamp post arm 30. The lamp post 10 is provided with a first connector 20, and the lamp post arm 30 is provided with a second connector 40. When the lamp post 10 and the lamp post arm 30 need to be installed, they are precisely positioned by engaging with the outer wall of the lamp post 10 through the groove 44, without repeated adjustments. Based on the weight of the lamp post arm 30 itself, the first inclined contact surface 24 and the second inclined contact surface 45 are tightly pressed together, so that the lamp post arm 30 is not easy to shake at the connection point of the lamp post 10, and it is convenient to install and tighten screws.

[0006] A gravity-based connection structure for a lamp post arm includes a lamp post 10 and a lamp post arm 30. The lamp post 10 is provided with a first connector 20, and the lamp post arm 30 is provided with a second connector 40.

The slanted hook 43 is also provided with a second slanted contact surface 45. When the lamp post 10 and the lamp post arm 30 need to be installed, the groove 44 engages with the outer wall of the lamp post 10, and the first slanted contact surface 24 and the second slanted contact surface 45 are tightly pressed together by the weight of the lamp post arm 30.

[0007] Furthermore, the first inclined contact surface 24 is an outward and upward plane, and the second inclined contact surface 45 is an outward and downward plane, so that the first inclined contact surface 24 and the second inclined contact surface 45 are tightly attached together.

[0008] Furthermore, the lamp post 10 is provided with a first mounting hole, and the first connector 20 is provided with a first through hole 21. When the first connector 20 is welded to the lamp post 10, the first mounting hole and the first through hole 21 are connected.

[0009] Furthermore, the lamp post arm 30 is provided with a second mounting hole, and the second connector 40 is provided with a second through hole 41. When the second connector 40 is welded to the lamp post arm 30, the second mounting hole and the second through hole 41 are connected.

[0010] Furthermore, when the lamp post 10 and lamp post arm 30 need to be installed, the first through hole 21 and the second through hole 41 are connected for wiring.

[0011] In some embodiments, the second connector 40 is provided with at least two second screw holes 42, and the first connector 20 is provided with at least two first screw holes 22 at corresponding positions. The positions of the second screw holes 42 and the first screw holes 22 correspond one-to-one. The second screw holes 42 are oblong holes, which facilitates screwing after alignment with the first screw holes 22.

[0012] Furthermore, the lamp post 10, lamp post arm 30, first connector 20, and second connector 40 are all made of aluminum alloy, which is lightweight and convenient for transportation.

[0013] Furthermore, the lamp post 10 is a polygonal or tapered structure with a smaller top and a larger bottom, which strengthens the overall structure of the lamp post 10 and makes it less prone to shaking when installed on the ground.
