Description
Technical field
The present invention relates to the navigation lights in boats and ships and ocean engineering field, more particularly, relate to the navigation lights that outer light shield is set.
Background technology
Under the prior art, though the navigation lights product in ship boats and ships and ocean engineering field is provided with interior shade, but be subject to light source and be non-spot light and light disadvantageous physical characteristic such as diffraction must take place by the shading edge, making shipyard difficulty very when the Installation and Debugging navigation lights.Industry never solves this difficult problem, weld fixed outer light shield design and occur at shipyard once in a while, but volume and weight is big.Obstruction is to the maintenance of lamp.
Summary of the invention
The invention provides a kind of navigation lights that outer light shield is set, it is little to aim to provide a kind of volume, in light weight, easy for installation, debugs the outer shading solution of novel accurately flexibly navigation lights.
In order to address the above problem, the present invention has constructed a kind of navigation lights that outer light shield is set, and comprises cylindric individual layer or double-deck navigation lights main body.The outer cylinder of cylindric navigation lights main body is provided with two arc light shields respectively with the center line left-right symmetry.Light shield comprises the outer arcuate cover plate, and the bottom connects the base plate of navigation lights main body base; Base plate is connected with fastening bolt by circumferential keyway with navigation lights main body base.At the intersection of left and right sides light shield, the both sides cover plate is with the interlace mode setting; And another side of cover plate is arranged to flanging.In addition, cover plate and base plate scribble the delustring black paint towards the surface of navigation lights main body.
Under the optimal way, screw and sliding connection plate are set respectively on the cover plate of both sides.Sliding connection plate is fixed in the edge of a side cover plate, and offers circumferential keyway on it, cooperates with screw to be used to be provided with nut, packing ring and bolt assembly.In order to strengthen the intensity of cover plate, prevent distortion, be provided with the strip reinforcement at the outer ledge of cover plate.
The present invention is exactly the problem that solves the accurate adjustable shading of navigation lights, and a kind of welded and installed facility of exempting from is provided, and is applied widely, the outer light shield solution of the navigation lights of debugging flexibility and reliability.Need to create one by one solving and merging to problems, 1. main purpose " shading ", the vertical shadow shield of circular arc relies on rotary mode to finish adjustable shading.2. exempt from welded and installed, send out a name slotted hole base, direct shared navigation lights lamp socket foundation bolt, finish fastening, according to a plurality of manufacturers navigation lights profile statistics.With most lamp socket size compatibilities.3. lightweight invention: the vertical shadow shield of circular arc self has structural strength, the corrosion-resistant corrosion allowance of removing of stainless steel. finish the lightweight function.Again above-mentioned functions and invention organic combination are in the same place, finish the outer light shield device invention of novel navigation lights.

The specific embodiment
Navigation lights comprises cylindric individual layer or double-deck navigation lights main body 21 as illustrated in fig. 1 and 2.
Referring to shown in Figure 3, the outer cylinder of cylindric navigation lights main body 21 is provided with two arc light shields 1 respectively in center line left-right symmetry mode.As Fig. 6, in conjunction with the Figure 4 and 5 explanation, light shield 1 comprises outer arcuate cover plate 16, and the bottom connects the base plate 11 of navigation lights main body 21 bases.Light shield cover plate 16, employing rolls, and is used for hiding, and absorbs the useless light of subduction.Light shield base plate 11 is connected by inferior arc-welding with the camber main body, is used for being connected with the lamp socket of service.
As shown in Figure 3, base plate 11 is connected with bearing pin by circumferential keyway with navigation lights main body 21 bases.At the intersection L of left and right sides light shield 1, both sides cover plate 16 is with the interlace mode setting.Two shadow shields have interference to overlap, and the skew back guarantees can light leak.
At this moment, shown in Fig. 3 and 6, the arc length of cover plate 16 is greater than the arc length of base plate 11, in case stop is when doing, the bottom seat board interferes.As shown in Figure 3, dotted line shows under two kinds of different adjustment modes with solid line, the position of light shield 1 of the present invention relation, keyway and bearing pin (or fastening bolt) that the base plate 11 among the figure under the two states can shared navigation lights base.
In addition, as shown in Figure 6, another side of cover plate 16 is arranged to flanging 12 and (or is claimed to cut the plain edge bar, as shown in Figure 6).Under the optimal way, cut plain edge bar 12, utilize the direct flanging of main body cover plate to form, can more effectively block light.
Shown in Fig. 7 and 8, under the optimal way,, all use all inner surface polishings of stainless-steel sheet T=1.5 1Cr18Ni9. coarse as C place base plate and D place cover plate with upper-part, be coated with the delustring black paint.
In addition, shown in Figure 4 and 5, screw 17 and sliding connection plate 14 are set respectively on the both sides cover plate 16.Among the figure, sliding connection plate 14 is fixed in the edge of right type cover plate 16; Connecting plate 14 is offered circumferential keyway, is used for cooperating with the screw 17 of levorotation cover plate, utilizes nut, packing ring and bolt assembly to be fixed as one.In addition, the securing member of sliding connection plate, preferred wing nut is exempted instrument when adjusting, manual fastening getting final product.Sliding connection plate 14 can be welded on main body.Be used for about two main body cover when sliding.The effect that connects and support is provided.
Among the figure, the outer ledge of cover plate 16 is provided with strip reinforcement 13.Reinforcement 13 utilizes arc black iron and main body cover welding, is used to make the conformal of camber main body cover.Above-mentioned number in the figure A represents center line.
The outer light shield device of ocean engineering navigation lights of the present invention has the ability of flexible adjustment, directly utilizes the navigation lights fastening bolt to fix, and exempts welded and installed.Utilize the bolt bearing pin to be rotated, reach the effect of flexible adjustment shading angle, veiling glare and the diffracted ray of navigation lights in the black light sector of code requirement eliminated.Have cost low, weather-proof, in light weight, debug characteristics easily.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
