The specific embodiment
As shown in Figure 1, the disclosed guard rail lamp mounting structure of the present invention comprises light fixture 1, and light fixture 1 is installed in the elongated slot of offering on the barrel of cylindrical shape guardrail 2 20.
Like Fig. 2~shown in Figure 6, light fixture 1 is made up of display part and mounting portion, and wherein the display part comprises wiring board 10, and several led light sources 11 are installed on the wiring board 10, and the light-emitting window place is covered with face shield 12.The mounting portion of light fixture 1 is the fixed support 13 that the aluminium alloy extrusions of fluting in the middle of is processed; In the both sides of fixed support 13 connector 14 is installed; Connector 14 is two arc aluminium alloy extrusions; Its inboard is provided with circular shaft 140, and circular shaft 140 penetrates in the arc chute 130 of fixed support 13 both sides setting, and circular shaft 140 can slide in chute 130 and rotate.On connector 14 surfaces, offer through hole 141, through hole 141 is between circular shaft 140 and connector outer 142.Hexagonal holding screw 15 in installing in the through hole 141.End cap 16 is installed at the two ends of fixed support 13, is installed on the fixed support 13 through screw 17.
The sectional view of fixed support 13 shown in Figure 3 is provided with platform 131 in the groove, the strip wiring board 10 that led light source 11 is installed is installed on the platform 131, and the heat that led light source 11 produces can dispel the heat by fixed support 13.Face shield 12 is installed in the notch place of fixed support 13, and through fluid sealant and fixed support 13 sealing and fixing.The both sides of fixed support 13 are provided with and are used for the arc chute 130 that connector 14 inboard circular shafts 140 penetrate.The internal diameter of this arc chute 130 is slightly larger than the external diameter of the circular shaft 140 on the connector, so that circular shaft 140 can slide in chute 130 and rotate.
The sectional view of connector 14 shown in Figure 4 on connector 14 surfaces of curved structure, is positioned at circular shaft 140 and offers two through holes 141 with 142 places, connector outer, and through hole 141 is used to install interior hexagonal holding screw 15.On 142 surfaces, outer of connector 14, a lot of bar anticreep lines 143 are set, so that when the madial wall 21 of this part and guardrail 2 is tightly fitted, increase frictional force.And; This part of fitting with the madial wall of guardrail 2 21 on the connector 14 is with respect to other parts of connector 14 certain degree of depth that caves inward; This degree of depth just in time equates with the thickness of guardrail sidewall; Like this, when light fixture 1 is installed in 2 last times of guardrail, the lateral wall of connector 14 exposed surfaces and guardrail 1 smoothly joins.
