A kind of signal lamp
Technical field
The present invention relates to the signal lamps in a kind of aircraft cabin, and square structure signal lamp is especially modified to circular configuration.
Background technique
The major function of signal lamp is the light signal for showing tape character in aircraft cabin, for reminding pilot or ground service people
Member.Currently, the shape of common traffic light system part is rectangular, and often specification is identical.It is rectangular when multiple unified specifications
When signal lamp is laid out together, it is easily reduced the recognition efficiency of pilot, increases the risk of maloperation.In order in shape to show
It distinguishes, a kind of circular signal lamp of demand.
Summary of the invention
The object of the present invention is to provide a kind of novel signal lamps, are improved on the basis of existing square structure,
To solve the problems, such as that existing signal lamp is all square structure.
To achieve the goals above, the technical scheme of the present invention is realized as follows: a kind of signal lamp, is used for aircraft cabin
It is interior, including,
One rectangular lamp holder has a first end and a second end, has in the lamp holder one to penetrate through its first end and the
The first accommodating cavity at two ends, the wall surface of the first accommodating cavity at the lamp holder first end are formed with one for backing plate receiving
Fixed groove;
One backing plate is contained in the fixed groove, which has one first loophole;
One annunciator mounting base, is set to first end side of lamp holder, which has a first end and one
Second end, the annunciator mounting base have one second loophole, which combines with the backing plate;
One circular annunciator installation lid is set to first end side of annunciator mounting base, annunciator installation lid tool
There are a first end and a second end, annunciator installation lid has a second accommodating cavity for penetrating through its first end and second end,
Wall surface of the second accommodating cavity at annunciator installation lid first end is formed with a butting section, which installs lid second
End is combined with the annunciator mounting base first end;And
One annunciator, uses transparent or semitransparent material, has a character or pattern displaying, the signal on the annunciator
Memorial tablet offsets in the second accommodating cavity and annunciator one side and the butting section of annunciator installation lid, another side and the letter
Number plate mounting base offsets.
As a kind of preferred embodiment of signal lamp, the combination and the letter of the annunciator mounting base second end and the backing plate
The combination of number plate installation lid second end and the annunciator mounting base first end is all connected by screw to.
As a kind of preferred embodiment of signal lamp, which is formed with a boss, which extends
Enter in the second accommodating cavity and offsets with the annunciator another side.
Compared with prior art, by technological means of the invention, existing square structure signal lamp is directly switched to justify
Shape structure improves the discrimination between each signal lamp, to reduce the possibility of maloperation.
Detailed description of the invention
Fig. 1 is structural exploded view of the invention.
Fig. 2 is structure assembling figure of the invention.

Specific embodiment
It elaborates with reference to the accompanying drawings and examples to the present invention.
Referring to Figure 1,2 and 3, shown in figure is a kind of signal lamp, is installed in aircraft cabin, and structure is mainly by a lamp
1, one backing plate 2 of seat, an annunciator mounting base 3, an annunciator 4 and annunciator installation lid 5 form.
The lamp holder 1 is square structure (i.e. the lamp holder of square signal lamp), has a first end and a second end, the lamp holder
The the first accommodating cavity (not shown) for penetrating through its first end and second end with one in 1, i.e., the thin wall box of bottomless uncovered should
Wall surface of the first accommodating cavity at 1 first end of lamp holder is formed with a fixed groove 11 accommodated for a backing plate.This first
There is a light source in accommodating cavity.
The backing plate 2 is square sheet, is contained in the fixed groove 11, making can not be opposite between the backing plate 2 and the lamp holder 1
Activity guarantees being connected firmly, reliably for backing plate 2.2 center of backing plate has circular first loophole 20.The four of the backing plate 2
A counterbore is respectively provided at a angle.
The annunciator mounting base 3 is circular configuration and uses light metal alloys, is set to 1 first end side of lamp holder,
The annunciator mounting base 3 has a first end and a second end, and it is rectangular which is formed with one
Boss 31, the annunciator mounting base 3 have circular second loophole 30.Have on the 3 second end end face of annunciator mounting base
There is through-hole corresponding with above-mentioned counterbore, is combined the annunciator mounting base 3 with the backing plate 2 by screw 6.
The annunciator installs lid 5 and is circular configuration and uses light metal alloys, is set to the annunciator mounting base 3 the
One end, the annunciator install lid 5 have a first end and a second end, the annunciator install lid 5 have one perforation its first
The second accommodating cavity (not shown) at end and second end, the second accommodating cavity is at annunciator installation 5 first end of lid
Wall surface is formed with a butting section 51.It is spherical concave surface that the annunciator, which installs 5 first end end face (including butting section 51) of lid, to meet
The pressing of finger shape.The annunciator installs tool on 5 second end end face of lid, and there are four counterbores.Have in the annunciator mounting base 3
The annunciator mounting base 3 is installed lid 5 with the annunciator by screw 6 and combined by the corresponding through-hole of above-mentioned counterbore.
The annunciator 4 is square structure, uses the engineering plastics of transparent or semitransparent material, stamps on the annunciator 4
The character 40 of display in need, which is located in the second accommodating cavity and 4 one side of annunciator is installed with the annunciator
The butting section 51 of lid 5 offsets, and another side and the boss 31 of the annunciator mounting base 3 offset.
When installation, first backing plate 2 is placed in fixed groove 11, then annunciator mounting base 3 is combined with the backing plate 2,
Annunciator is placed on boss 31, finally, annunciator installation lid 5 is combined with annunciator installation lid 5, to be fixed letter
Number plate 4, as shown in Figure 2.
The light that 1 inner light source of lamp holder projects successively exposes to annunciator through the first and second light hole 20,30, to reach display
The purpose of character.
Embodiments of the present invention are only expressed above, and the description thereof is more specific and detailed, but can not therefore understand
For the limitation to patent of invention range.It should be pointed out that for those of ordinary skill in the art, not departing from this hair
Under the premise of bright design, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.Therefore, this hair
