Wherein the screen box body is integrally formed, and the screen box body is provided with a reinforcing rib and a positioning device. A sealed rubber ring is provided between the screen box body and the back plate. The utility model has the advantages of good sealing property and good heat radiation property.
Description
[technical field]
The utility model relates to a kind of closed screen box that is used to install LED display.
[background technology]
The range of application of large LED display screen (below abbreviate as LED screen) is more and more wider, and it can be applicable to various occasions such as outdoor advertising, physical culture, traffic, performance, exhibition, lease, rally.And the screen case of these LED screens all need be installed in the open air, and it usually is directly exposed in sunlight, the wind and rain, so LED screen case need can prevent that rainwater, foreign material etc. from entering, to avoid the causing faults such as short circuit of screen case inside to occur.And existing LED screen case lower backside all leaves a louvre or radiating groove, though it can prevent that under general condition rainwater from entering, but under atrocious weather (as storm), rainwater or foreign material can enter screen case inside inevitably from louvre or radiating groove, so can cause the damage of screen case inside.
[utility model content]
Can not prevent that for overcoming existing LED screen case rainwater from entering the deficiency of screen case inside, and provide a kind of closure good LED closed screen box.
The technical scheme that the utility model adopted is: LED closed screen box provided by the utility model, include LED mask plate, screen case body and backboard, it is characterized in that: this body by integral forming of screen case, and the locating device that on screen case body, is provided with reinforcement and is used for positioning with the LED mask plate.
Described screen case body is provided with this screen case and the fixing stationary installation of installation material.
Be provided with O-ring seal between described screen case body and the backboard.
The edge of described O-ring seal embeds in the groove of screen case body.
Described locating device is pilot hole or reference column.
Described stationary installation includes thread bush, spring washer and bolt.
The beneficial effects of the utility model are: in the utility model, screen case body is formed in one, but not form by many parts winding, and between screen case body and backboard, increase an O-ring seal, so screen case body and backboard and mask plate have constituted the structure of a complete closed, improved the water resistance of screen case.

[embodiment]
Seeing also Fig. 1～Fig. 5 and shown in Figure 12, is the synoptic diagram after enlarged drawing, rear view and the assembling of front elevation, A-A sectional view, B-B sectional view, C of the utility model LED closed screen box body; This screen case includes screen case body 1, backboard 2 (see figure 6)s and LED mask plate 5.Wherein, screen case body 1 is that aluminium (or metal material that other thermal diffusivities are good, proportion is less) die casting forms, and LED mask plate 5 can be installed in its front, and backboard 2 is installed in its back; The outer wall of this screen case body has vertical kink (among the figure not label), so the overall appearance of this body is: the part that backboard is installed greatly near the part of mask plate is little, promptly stretch out a circle outer rim around the part near mask plate, the stationary installation 13 on this outer rim of mat can be fixed on this screen case above the installation material (as assembly wall).And the inner space 17 that this outer wall surrounds is used to lay the devices such as circuit board of control LED work.
Below in conjunction with Fig. 1～Fig. 5, stress the structure of screen case body 1.The front of this screen case body 1 is a plate body, and this plate body center section is the thread hollow structure, and is provided with cross reinforcement 11 at the center section of this plate body, is provided with stiffener 12 on plate body; Establish a plurality of locating devices 14 on plate body, cross reinforcement 11 and stiffener 12, this locating device 14 can be a pilot hole, also can be reference column, and this locating device 14 can match with the locating device on the mask plate.
Be provided with groove 10 at the end that backboard 2 is installed on the screen case body 1.
As shown in Figure 4, stationary installation 13 is a through hole as can be known, and it includes thread bush 130, spring washer 131 and stainless steel erection bolt 132.
As Fig. 6～shown in Figure 8, this backboard is a sheet metal, it has good heat dispersion, and backboard 2 is provided with fixed orifice 21, locating device 22 and external hole 20 with the one side that matches in the rear end of screen case body, and this external hole 20 can be passed through such as power cable and data line.
As Fig. 9～shown in Figure 11, the O-ring seal 3 of the utility model LED closed screen box is to be used between backboard 2 and the screen case body 1, its edge can embed in the groove 10 of screen case body 1, utilize fixed orifice 21 again, backboard 2 and screen case body 1 can be combined closely, can enter screen case inside to prevent water or foreign material.
In the utility model, screen case body is formed in one, but not form by many parts winding, and between screen case body and backboard, increase an O-ring seal, so screen case body and backboard and mask plate have constituted an enclosed construction, improve the water resistance of screen case, can increase the serviceable life of screen case.
