Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a supporting foot of a lifting lighting lamp and the lifting lighting lamp. Background Art

[0002] Lifting lighting is a lighting fixture used in outdoor environments without lighting facilities. With the development and improvement of urban facilities, lighting facilities are becoming increasingly popular. Lifting lighting is more often used in outdoor environments with uneven ground, such as mountainous environments. The uneven ground has put forward new requirements for the supporting structure of lifting lighting.

[0003] Existing outdoor lifting lighting lamps are usually supported by structures such as a foot that can be deployed and retracted and a support rod for supporting the foot. Usually, one end of the foot is pivotally connected to the bottom of the lifting lighting lamp, and one end of the support rod is pivotally connected to the foot. By adjusting the height of the other end of the support rod, the deployment angle of the foot is adjusted to make it fit the ground, thereby ensuring that the foot can provide effective support for the automatic lifting lighting lamp.

[0004] Existing related structures mainly include two categories. One is to set a number of teeth on the vertical rod fixed to the other end of the support rod, and adjust the expansion angle of the foot by clamping the other end of the foot on different teeth; the other is to set a number of holes on the support rod, and limit the other end of the support rod to different holes through pins to adjust the expansion angle of the foot. However, both of the above methods have the defect of limited adjustment accuracy. The adjustment range of the expansion angle of the foot is limited by the density of the aforementioned teeth or holes, and is not applicable in actual application. It cannot be guaranteed that the foot will be able to fit into the ground and form an effective support. Utility Model Content
