Municipal garden street lamp fixing device

Abstract

The invention discloses a municipal garden street lamp fixing device. A concrete slab is embedded underground, a screw is arranged in advance, a base plate is placed on the concrete slab, a fixing base is placed on the base plate, and the screw penetrates the base plate and the fixing base to be fastened through a nut; a through groove is formed in the fixing base, a first through hole is further formed, a second through hole is formed in the base plate, a counter bore is formed in the concrete slab, and the diameter of the second through hole and the diameter of the counter bore are both slightly larger than the outer diameter of a stand column; one end of the stand column penetrates the first through hole, the second through hole and the counter bore to abut against the lower bottom face of the counter bore, and the other end of the stand column extends out of the fixing base; and the end, extending out of the fixing base, of the stand column is provided with a flange. The municipal garden street lamp fixing device has the beneficial effects that the stand column is directly inserted into the concrete slab, so that stress of the fixing base is reduced; meanwhile, an anti-looseness nut is installed outside the through groove, and therefore use is facilitated; a waterproof cover is further installed, efficacy losing of an internal bolt can be reduced, the using effect of the device is guaranteed, installation is convenient, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the field of street lamp fixing equipment, and in particular relates to a municipal garden street lamp fixing device. Background technique [0002] Because LED lights have the characteristics of high efficiency, low consumption, energy saving, environmental protection, and long life, more and more countries around the world pay more and more attention to them. LED lights are used in urban roads, expressways, tunnels and other environments, and play an important role in urban traffic, public security, and beautification. , if the street lights cannot work normally, it will not only affect the image of the city, but also cause traffic safety accidents. With the development of the times, LED street lights have emerged; and road lighting is closely related to people's production and life. With the advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistanc...

Problems solved by technology

[0006] Third: The screw embedded in the concrete is only in the form of a straight column. After shaking for many times, there may be a gap between the screw and the concrete slab, which will affect its safety;

[0007] Fourth: Only connect the lamp post through the flange. If one bolt of the flange connection fails, it may cause the rest of the bolts to be stressed and accelerate their failure speed.
