Abstract

An embedded bus LED display screen housing for a bus overcomes the technical problems of large size, too much display windows and poor leak tightness of the prior bus display screen of which the entire housing is exposed. The technical scheme adopted by the utility model is that an upper housing and a lower housing mounted and fixed therein through screw fastening are included, wherein right-angled edges are folded downwards from the periphery of a panel of the upper housing, a guard plate extending downwards is welded in the right-angled edges on the periphery of the panel of the upper housing, a fixing stop block for fixing LED cell boards is welded on a bottom plate of the lower housing, standing plates extending upwards are arranged on the four edges of the bottom plate, two through holes are formed on the front and the back standing plates, connecting screw caps are welded in the through holes, and a transparent acrylic board is mounted between the panel of the upper housing and the lower housing. Compared with the prior art, the embedded bus LED display screen housing has the advantages of simple structure, convenient installation and maintenance, small size, good sealing performance, dust-proof, damp-proof and antistatic effects, and longer service life.

Description

Embedded bus LED display shell

Technical field

The utility model belongs to the Machining Technology field, particularly a kind of embedded bus LED display shell that is used for bus.

Background technology

Prior art is used for bus display screen technology shell, as the disclosed public transport display screen of CN200820153464.6 shell, is directly installed on the car body of bus, the entire display screen shell all is exposed to outside the car body, take up room, display window is more, and poor sealing.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, and a kind of good seal performance is provided, and it is little to take up room, embedded bus LED display shell easy to installation and maintenance.

The technical solution adopted in the utility model comprises upper shell and lower house, described lower house is installed in the upper shell and with screw and is connected and fixed, described upper shell has a panel, in the middle of panel, have a rectangle display window, around panel, fold the right angle flanging downwards, around panel, be welded with the backplate of downward extension in the right angle flanging, be processed with the elongate slot that is used to regulate the upper shell height on backplate, panel bottom surface in both sides is welded with the attachment screw that is used to be fixed on the bus outside backplate; Described lower house has a base plate; on base plate, be welded with four fixed stops that are used for fixing the LED cell board; be processed with one in the centre of base plate and be used for the centerline hole that power lead and signal wire pass through; and the gum cover that is used to protect power lead and signal wire is installed in this centerline hole; there is upwardly extending riser on four limits at base plate; on the riser of front and back, respectively be processed with two through holes; and be welded with coupling nut therein, between the panel of upper shell and lower house, transparent acrylic board is installed.

During use, the LED cell board is installed in four fixed stop spaces of lower house, magnetic post by the LED cell board links together LED cell board and lower house magnetic, the left and right sides at the LED cell board, also be connected and installed with power panel and control card by magnetic, the signal wire of the power lead of power panel and control card and LED cell board passes outside lower house by the centerline hole in the middle of the lower house base plate, lower house is installed in the backplate of upper shell then

In the actual installation of bus, leave one in the car body installation position of bus according to the utility model backplate physical size and window is installed and corresponding to the screw hole of the utility model attachment screw, upper shell backplate of the present utility model and lower house are partly embedded in the car body of bus, by attachment screw connection and fixing, have only upper shell panel and flanging partly to expose on car body.

Compared with prior art, the utility model is simple in structure, and is easy to installation and maintenance, and has following two outstanding substantive distinguishing features:

1. when being installed on the bus owing to the employing damascene structures, upper shell backplate and lower house part all are embedded in the car body, have only upper shell panel and flanging partly to expose on car body, so it is little to take up room;

2. because at the panel of upper shell and be installed between the LED cell board on the lower house transparent acrylic board is installed, LED cell board and power panel and control card all are sealed in the lower house and by transparent acrylic board and seal, so good seal performance, dustproof, protection against the tide and antistatic effect are good, can prolong the serviceable life of product;

Embodiment:

As depicted in figs. 1 and 2, the technical solution of the utility model comprises upper shell 1 and lower house 2, and described lower house 2 is installed in the upper shell 1 and is connected and fixed with screw 3, and transparent acrylic board 4 is installed between upper shell 1 and lower house 2;

As Fig. 3～shown in Figure 6, described upper shell 1 has a panel 1-1, in the middle of panel 1-1, have rectangle display window 1-2, around panel 1-1, fold right angle flanging 1-3 downwards, panel 1-1 bottom surface around panel in the right angle flanging 1-3 is welded with the backplate 1-4 of downward extension, on backplate 1-4, be processed with the elongate slot 1-5 that is used to regulate the upper shell height, outside backplate 1-4, be welded with the attachment screw 1-6 that is used to be fixed on the bus on the panel 1-1 the inside of front and back two side bodies;

As Fig. 7～shown in Figure 9; described lower house has a base plate 2-1; on base plate 2-1, be welded with four fixed dam 2-2 that are used for fixing the LED cell board; be processed with one in the centre of base plate 2-1 and be used for the centerline hole 2-3 that power lead and signal wire pass through; and the gum cover 2-4 that is used to protect power lead and signal wire is installed in this centerline hole 2-3; four edge breaks at base plate 2-1 go out upwardly extending riser 2-5, be processed with through hole and be welded to connect nut 2-6 therein on the riser of front and back.
