Background technology
Existing outdoor LED display screen mostly comprises a LED casing and is installed in the interior led module of LED casing.Led module comprises plastic cement drain pan, pcb board and plastic mask, and wherein, drain pan has a front surface and rear surface, and front surface is provided with the threaded hole for fixed visors and pcb board, and the rear surface is provided with for the threaded hole that drain pan is fixed on the LED casing.Be provided with LED on the front surface of pcb board, face shield, pcb board from front to back successively combination stacked and by M1.7 * 8 machine tooth screws and threaded hole face shield and pcb board are fixed on the front surface of drain pan.Pass the LED casing at the rear portion of LED casing with M3 * 8 machine tooth screws again and be combined with threaded hole drain pan is fixed in the LED casing.For anti-sealing enters from LED casing rear portion, between LED casing and drain pan, also be provided with waterproof washer.
As seen, existing led module all is that maintenance mode designs after adopting.During installation, enough service clearances should be left in LED casing rear portion, so as when to break down from the dismounting of LED casing rear portion or maintenance led module.But, at some special occasions, can't reserve enough service clearances at LED casing rear portion, the led module of LED display is if there is burning out, and perhaps other electron device damages, and just can't keep in repair.
The utility model content
The utility model is for maintenance mode design after solving the prior art LED display and adopting, and the technical matters that causes special occasions to keep in repair provides and safeguarded water-proof type LED display screen before a kind of.
The utility model adopts following technical scheme to realize: safeguard water-proof type LED display screen before a kind of, comprise led module and LED casing, led module comprises from front to back face shield, pcb board and the drain pan of successively stacked connection, and led module is fixed in the LED casing.
Wherein, pcb board is fixed on the front surface of drain pan by screw, and described face shield, pcb board and drain pan are connected screw or snap-in structure is fixed in the LED casing after the connection from front to back successively.
Wherein, the power circuit that have at least controller on the pcb board, connects controller respectively is connected synchro control card and the asynchronous control card of connection display driver circuit with display driver circuit.
Wherein, power circuit connects a supply socket that exposes from the rear surface of drain pan.
Wherein, a nameplate that is used for the various parameters of mark LED display is set in the rear surface of drain pan.
Wherein, setting has a tooth hole on the upper side edge of drain pan, screws togather suspension ring in this tooth hole.
Wherein, behind the cancellation suspension ring, screw togather a plug that prevents ponding in the tooth hole.
Compared with prior art, the utlity model has following beneficial effect:
The utility model passes through face shield, pcb board and drain pan are stacked successively from front to back, and can dismantle in the past and be fixed in the LED casing, compared to existing technology from LED casing rear fixed L ED module, no longer need to reserve service clearance at the rear portion of LED casing, directly can dismantle from the place ahead the led module maintenance, need not to tear open the interior any parts of LED casing can take off led module, do not damage modular unit, reached the technique effect of safeguarding quickly and easily, the technical matters that can't keep in repair when efficiently solving prior art LED display rear portion without service clearance, make and install and keep in repair convenient, adapt to the place wider.
Description of drawings
Fig. 1 is the decomposition texture schematic diagram of the utility model led module;
Fig. 2 is the part-structure schematic diagram that suspension ring are set on the drain pan;
Fig. 3 is the part-structure schematic diagram that the drain pan top cement plug is blocked suspension ring tooth hole.
Embodiment
As shown in Figure 1, the utility model proposes and safeguard water-proof type LED display screen before a kind of, it comprises led module and LED casing.Wherein, face shield 1, pcb board 2 and the drain pan 3 of from front to back successively stacked connection of led module, described pcb board 2 is fixed on the front surface of drain pan 3 by screw, and described face shield 1, pcb board 2 are connected with drain pan to be fixed in the LED casing after can connecting successively from front to back by screw or snap-in structure and (are not shown among Fig. 1).
Like this, each led module can be dismantled in the past and be fixed in the LED casing, compared to existing technology from LED casing rear fixed L ED module, no longer need to reserve service clearance at the rear portion of LED casing, directly can dismantle from the place ahead the led module maintenance, need not to tear open the interior any parts of LED casing can take off led module, does not damage modular unit, has reached the technique effect of safeguarding quickly and easily.
Wherein, comprise at least on the pcb board 2: controller; The power circuit and the display driver circuit that connect respectively controller; And the synchro control card and the asynchronous control card that connect display driver circuit, realize two kinds of playing functions of synchronous asynchronous.
In addition, the supply socket 31 that connects power circuit exposes from the rear surface of drain pan 3, and the airplane power source socket of full waterproof is adopted in supply socket 31.
In addition, a nameplate 32 that marks the various parameters of LED display is set in the rear surface of drain pan 3.
In conjunction with Fig. 2 and shown in Figure 3, arrange on the upper side edge of drain pan 3 and have a tooth hole 33, screw togather suspension ring 34 in this tooth hole 33, can directly LED display be sling by suspension ring 34 is mounted among the LED casing.After LED display installs, suspension ring 34 are taken off, be blocked among the tooth hole 33 with plug 35, play the effect that prevents ponding.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
