Telltale in a kind of compartment

Technical field

The present invention relates to the block construction in a kind of railway car, refer in particular to the structure of Customer information telltale in a kind of railway car.

Background technology

Along with the development of high speed motor car, for the display device structure size in the compartment, thickness, length and Secretary is highly arranged, and also very large of the amount of requirement product, for small size, undersized product is installed and assembling also is a difficult point.Traditional panel beating mode addresses these problems all relatively difficulty, and the volume and weight that takies is large, and assembling is inconvenient.

At present, the display device structure in the most common compartment is by the panel beating bending, then adopts welding, and the mode of screw assembling is finished the display device structure framework.Mainly there are following some shortcomings in existing sheet metal structural:

1, existing sheet metal structural mode, more complicated aspect production technology, the operation of employing is loaded down with trivial details, so inconvenient a large amount of production and manufacturing;

2, adopt the mode of sheet metal structural, owing to generally use now carbon steel material, and aspect explained hereafter, structure design is had a lot of restrictions, so can make the sheet metal structural volume relatively large, quality is heavy;

3, the display device structure of existing panel beating, the most frequently used mode are to adopt screw to connect, so be inconvenient to assemble and produce.

Therefore, necessary display device structure in the existing compartment is improved.

Summary of the invention

The object of the invention is to for existing deficiency, the telltale in a kind of new compartment of proposition, the display device structure in this compartment is compacter, and profile is also more attractive in appearance.

The objective of the invention is to be achieved through the following technical solutions:

Telltale in a kind of compartment, adopt frame type combined structure, comprise two girders, be divided into girder I and girder II, two side plates, a cover plate, two girders are installed relatively, two girder sides side plate are installed respectively, form a quadrilateral frame casing, by monolateral articulated manner cover plate is installed on the girder I therein, the cover plate hinge through of can having mercy on, the centre portion on the cover plate is lens, scioptics can be seen the read-out in the telltale, read-out is installed in the midway location in the quadrilateral frame casing, and wherein read-out is close to the lens position installation of cover plate; Pcb board (claiming again printed circuit board (PCB)) is installed in the back side of quadrilateral frame casing.

Further, be drilled with through hole on the inner convex platform of described girder I, the centre portion that passes through is hinge mounting hole, stainless hinge is installed in the hole, a hinge part is installed in the through hole of inner convex platform of girder I, and some is connected with the boss of cover plate in addition, forms a hinge means.

Further, described side plate by screw and erection of main beam together, wherein, inner face at two girders is provided with the screw installation base, have screw mounting hole on the boss, on the side plate with the inner face boss of two girders on the corresponding through hole that has of screw mounting hole, mounting screw passes the through hole on the side plate, be installed in the screw mounting hole on the inner face boss of two girders, the end portion of the hinge mounting hole of other two girders also is screw, correspondence position with the hinge mounting hole of two girders on the side plate also has through hole, mounting screw passes the through hole on the side plate equally, be installed in the screw of hinge mounting hole of two girders, the integral body that forms the quadrilateral frame casing is fixed.

Further, described pcb board is to be stuck in the draw-in groove that inner face boss and back-up block by two girders form, and the inner face boss of two girders is on the one hand as the screw installation base of quadrilateral frame casing, on the other hand as the chucking projection of pcb board.

Further, described girder II is provided with the installation ear, ear is installed is fixed on the girder II by fastener; The installation ear also is installed on side plate, ear is installed is fixed on the side plate by fastener.

The invention has the advantages that:

The present invention adopts the framework combined structure of profile form, and by the combination of some modules to the quadrilateral frame casing, and the device in the casing fixedly positions, simplified installing device, and convenient the installation, and pcb board cooperates by the spacing tolerance between the section bar, by left and right sides panel and section bar pcb board is fixed, cover plate can rotate by stainless steel bar, and fix screw carries out an other end to be tightened, thereby realizes the fixing of cover plate.The mode of cover plate by stainless rotation can make installs and easy to assembly, and the mode of section bar by screw and tolerance fit overlaps and connect, can make that structure becomes simply; Adopt aluminium alloy extrusions, can make structure lighter and handier.The total pattern can be finished aspect distortion and the manufacturing efficiently.
