Abstract
The utility model provides a locomotive indicating lamp comprising a transparent lampshade, of which the center portion is provided with a hemispherical curved surface, four corners are provided with arched notches, and the inner surface is provided with a plurality of positioning holes; a lamp socket, of which the upper surface is provided with positioning columns at places corresponding to the positioning holes; a printed circuit board fixed on the upper surface of the lamp socket through threaded connection; a light barrier which is located above the printed circuit board and has four through holes, through which the positioning columns are inserted into the positioning holes when the transparent lampshade is nested in the lamp socket; and a rear cover, which is located under the lamp socket and fixedly connected to the lamp socket through a plurality of screw holes. Connection between the transparent lampshade and the lamp socket can be secured through cooperation between the positioning holes of the transparent lampshade and the positioning columns of the lamp socket.
Description
Technical Field
The utility model relates to a locomotive pilot lamp framework among the railway signal processing.
Background
It is often necessary to install a dedicated indicator light on the locomotive during locomotive travel in order to provide an accurate signal indication to the associated command or personnel ahead of the railroad. However, the conventional indicator light is easy to loosen or fall off due to shaking when the locomotive travels, and in addition, the lampshade and the lamp holder of the indicator light are also displaced, so that the connection reliability between the lampshade and the lamp holder is poor. On the other hand, when the lamp tube in the lampshade emits light, most of the existing lampshades have poor light-gathering performance, and the signal indication function of the indicator lamp is reduced to a certain degree.
In view of this, how to design a stable structure of the indicator light for the locomotive is a subject faced by related technical personnel in the industry.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that locomotive pilot lamp exists when using among the prior art, the utility model provides a novel locomotive pilot lamp.
According to the utility model discloses an aspect provides a locomotive indicator, include:
the middle part of the transparent lampshade is provided with a hemispherical curved surface, four corners in the transparent lampshade are provided with arc notches, and the inner surface of the transparent lampshade is provided with a plurality of positioning holes;
the upper surface of the lamp holder is provided with a positioning column at a position corresponding to the positioning hole;
the printed circuit board is fixed on the upper surface of the lamp holder through threaded connection;
the light barrier is positioned above the printed circuit board and provided with four through holes, and when the transparent lampshade is embedded with the lamp holder, the positioning column penetrates into the positioning hole through the through holes; and
and the rear cover is positioned below the lamp holder and is fixedly connected to the lamp holder through a plurality of screw holes.
Preferably, the area of the printed circuit board is smaller than or equal to the area of the light barrier. Further, the printed circuit board has a plurality of support posts between the printed circuit board and the light barrier.
Preferably, two corresponding sides of the lamp holder comprise a C-shaped mounting seat, and the mounting seat comprises a round hole.
Preferably, the lamp tube of the locomotive indicator light is an LED.
Adopt the utility model discloses a locomotive pilot lamp, utilize transparent lampshade's locating hole with the reference column of lamp stand cooperatees to make the connection between transparent lampshade and the lamp stand more firm, in addition, be located printed circuit board and the barn door above the lamp stand upper surface loop through threaded connection and perforating hole and fix, make this locomotive pilot lamp become more succinct and pleasing to the eye.
Drawings
Various aspects of the present invention will become more apparent to the reader after reading the detailed description of the invention with reference to the attached drawings. Wherein,
fig. 1 shows an overall configuration diagram of a motorcycle indicator light according to the present invention.
Detailed Description
The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.
A preferred embodiment of the present invention is described below:
the locomotive indicating lamp comprises a transparent lampshade 1, a lamp holder 2, a printed circuit board (not shown in the figure), a light barrier (not shown in the figure) and a rear cover 3. The middle part of the transparent lampshade 1 is provided with a hemispherical curved surface, four corners in the transparent lampshade 1 are provided with arc-shaped notches, and the inner surface of the transparent lampshade 1 is provided with a plurality of positioning holes. The upper surface of the lamp holder 2 is provided with a positioning column at a position corresponding to the positioning hole, and the printed circuit board is fixed on the upper surface of the lamp holder 2 through threaded connection. The light barrier is positioned above the printed circuit board and is provided with four through holes, and when the transparent lampshade 1 is embedded with the lamp holder 2, the positioning column penetrates into the positioning hole through the through holes. The rear cover 3 is positioned below the lamp holder 2 and is fixedly connected to the lamp holder 2 through a plurality of screw holes.
In a preferred embodiment, the area of the printed circuit board is smaller than or equal to the area of the light barrier, so that the light barrier can reflect all the light emitted by the lamp tube when the light travels downwards. Furthermore, the printed circuit board is provided with a plurality of support columns which are positioned between the printed circuit board and the light barrier, and the support columns can enable the heat dissipation elements on the printed circuit board to effectively exchange heat in certain space, so that the normal work of parts on the printed circuit board can be continuously ensured.
In another embodiment, both corresponding sides of the lamp holder 2 comprise a "C" shaped mounting seat, and the mounting seat comprises a circular hole.
Preferably, the lamp tube of the locomotive indicator light is an LED.
Adopt the utility model discloses a locomotive pilot lamp, utilize transparent lampshade's locating hole with the reference column of lamp stand cooperatees to make the connection between transparent lampshade and the lamp stand more firm, in addition, be located printed circuit board and the barn door above the lamp stand upper surface loop through threaded connection and perforating hole and fix, make this locomotive pilot lamp become more succinct and pleasing to the eye.
The above-mentioned embodiments are only one of the preferred embodiments of the present invention, and the general changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
