Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and in particular to a street lamp. Background Art

[0002] The existing street lamp structures are all structures in which the support rod and the lamp part are stationary relative to the support base fixed to the ground, and all the support structures are integrated, and the support base is connected to the ground where it is needed by connecting parts such as bolts and nuts.

[0003] Specifically, the existing street lamp structure is a fixed "7"-shaped structure with a base fixed to the ground and cannot be moved, and the head of the "7"-shaped structure faces the center of the road where light needs to be illuminated. The structure is rigid, and when the lamp tube has a problem and needs to be replaced, special on-board equipment and a large number of manpower are required to complete the replacement. In this process, at least one special vehicle with a lift and two operators are required to complete it. Moreover, since the lamp mouth faces the center of the road, the special vehicle needs to be parked in the center of the road when replacing it, and it takes at least ten minutes to wait for the replacement. Therefore, with the increasingly developed traffic and increasingly congested roads today, such a structure can no longer meet the existing traffic needs.

[0004] Therefore, how to provide a street lamp that can facilitate the replacement of lamp tubes without affecting the driving of vehicles in the lane has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0011] In a preferred embodiment of the present invention, both ends of the screw rod have hexagonal grooves.

[0012] In a preferred embodiment of the present invention, the street lamp further includes: a rotating structure, which is arranged between the first sub-support rod and the supporting base; the rotating structure uses a pair of bearings to support the first sub-support rod, and limits the first sub-support rod to move along its own axial and radial directions, so that the first sub-support rod can only rotate along its own circumferential direction.

[0013] In a preferred embodiment of the present invention, a protective structure is sleeved at the connection between the first sub-support rod and the second sub-support rod, and the protective structure can move along the second sub-support rod in a direction away from the first sub-support rod.
