A kind of LED display unit safeguarded before convenience
Technical field
The utility model relates to LED display unit, the LED display unit safeguarded before especially a kind of convenience.
Background technology
At present, large LED display screen application is very wide, and these large LED display screens are typically mounted on skin. and large LED display screen is all made up of multiple LED display unit splicings, LED display unit by quadra, be embedded in the LED display module of side, quadra face, be arranged in quadra to include the circuit board of the components and parts such as HUB plate, D/C power, receiving card, quadra dorsal part is provided with the bonnet of its closing. the signal union joint of LED display unit and power connector are then arranged on the quadra outside bonnet. based on the narrow space (as shown in Figure 2) between large LED display screen and skin, attendant generally cannot be introduced into this crawl space and the devices such as LED display back signal union joint and power connector keeped in repair. therefore, it is arranged on the devices such as the large LED display screen back signal union joint on skin and power connector for convenience to keep in repair, the bonnet of each LED display unit dorsal part of composition large LED display screen all can arrange the rear window of a configuration bonnet door, when attendant needs the devices such as LED display unit back signal union joint and power connector are keeped in repair, would generally first will be embedded in the LED display module of side, quadra face to take off, then hands is stretched into quadra and opens bonnet behind the door, namely LED display unit back can be reached into by rear window, the components and parts at display screen back are keeped in repair. existing LED display unit bonnet door is as in figure 2 it is shown, overturn structure bonnet door for hinge, and namely the side of bonnet door is connected with rear window side jamb by hinge, utilizes hinge bonnet door can be rotated about 90 degree.Enough opening under special case even if the convertible bonnet door of this hinge is backed with at display screen, bonnet door hinge connects the space of side and is still isolated. When the display screen back side and metope metric space are less, then the unlatching of this hinge convertible bonnet door will be restricted, as shown in Figure 3. The too small open degree of bonnet door can affect attendant undoubtedly and reach into convenience and the motility that the components and parts such as signal connecting line and electric power connection line are safeguarded by display screen unit back.

The technical problems to be solved in the utility model is to make up above-mentioned the deficiencies in the prior art, it is provided that the LED display unit safeguarded before a kind of convenience.
The LED display monotechnics problem safeguarded before convenience of the present utility model is solved by the following technical programs.
The LED display unit safeguarded before this convenience, including: quadra, the LED display module being inlaid in side, quadra face, the HUB plate being arranged on quadra and D/C power, receiving card, quadra dorsal part is provided with the bonnet of its closing, and described bonnet offers rear window.
The feature of the LED display unit safeguarded before this convenience is: described rear window is equipped with a telescopic horizontal sliding bonnet door.
The technical problem of the LED display unit safeguarded before this utility model is convenient is solved by the following technical programs further.
Described telescopic horizontal sliding bonnet door is made up of with the hinge arms mechanism being symmetrically mounted on door closure both sides door closure, and the another end of two hinge arms mechanisms is connected with rear window both sides jamb respectively.
Described hinge arms mechanism is made up of front hinge seat, rear hinge seat, front hinge arms, rear hinge arms, described front hinge arms one end and rear hinge arms one end are hinged by short rotating shaft, and front hinge arms and rear hinge arms two ends after being hinged are hinged by two root length rotating shafts and front hinge seat, rear hinge seat with front hinge seat, rear hinge seat respectively; Front hinge seat is fixing with rear window both sides jamb to be connected, and rear hinge seat is fixing with lid door to be connected.
This utility model compared with prior art provides the benefit that:
The LED display unit design science safeguarded before this utility model is convenient, simple and reasonable, the application on LED display unit bonnet of the telescopic horizontal sliding bonnet door, can solve display screen installation environment less when, bonnet door still can be opened without dead angle. Add attendant and reach into the motility that the components and parts such as display screen back signal connecting line and electric power connection line carry out dismantling or safeguarding. This more traditional LED display unit being provided with hinge-type bonnet door of LED display unit being provided with telescopic horizontal sliding bonnet door saves the installing space of display screen on using so that the range of application of this type of display screen unit is wider.
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.

Detailed description of the invention
Embodiment: from Fig. 4 and Fig. 5 it will be clear that the LED display unit safeguarded before convenient is essentially identical with the structure of existing LED display unit, including quadra 1, it is inlaid in the LED display module 2 of 1 side of quadra, is arranged on quadra 1 and includes the circuit board 3 of the components and parts such as HUB plate, D/C power, receiving card, quadra 1 dorsal part is provided with the bonnet 4 of its closing, offering rear window 5 on described bonnet 4, described rear window 5 is equipped with a telescopic horizontal sliding bonnet door 6.Quadra 1 outside bonnet 4 is additionally provided with signal union joint 7 and on quadra 1 that power connector 8 is then arranged on, differs only in:
Described telescopic horizontal sliding bonnet door 6 is made up of with four the hinge arms mechanisms 62 being symmetrically mounted on door closure 61 both sides door closure 61, and the another end of four hinge arms mechanisms 62 is connected with rear window 7 both sides jamb respectively.
Described hinge arms mechanism 62 is as shown in Figure 6, it is made up of front hinge seat 621, rear hinge seat 622, front hinge arms 623, rear hinge arms 624, described front hinge arms 623 one end and rear hinge arms 624 one end are hinged by short rotating shaft 625, and front hinge arms 623 and rear hinge arms 624 two ends after being hinged are connected with the front hinge seat of front hinge seat 621, rear hinge seat hinge 622 by two root length rotating shafts 626,627 with front hinge seat 621, rear hinge seat 622 respectively. Described short rotating shaft 625, long rotating shaft 626,627 tail end be provided with C shape button 628.
Front hinge seat 621 is fixing with rear window 5 both sides jamb to be connected, and rear hinge seat 622 is fixing with door closure 61 to be connected.
It is clear from fig. 7 that, the LED display unit safeguarded before this convenience its compared with conventional hinges formula bonnet door, under the less situation identical with metope metric space of the display screen back side, the LED display unit safeguarded before this convenience is telescopic horizontal sliding bonnet door 6 owing to the rear window 5 of bonnet 4 has been equipped. The degree of opening an account of bonnet door 6 is more than conventional hinges formula bonnet door, add attendant and reach into the motility that the display screen back element to back keeps in repair, be also convenient for signal connecting line and power line and the attended operation of bonnet 4 external signal union joint 7 and power connector 8. The LED display unit safeguarded before this convenience saves the installing space of display screen on using so that the range of application of this type of display screen unit is wider.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations. For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, its framework form can be flexible and changeable, it is possible to subseries product. Simply make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that this utility model is determined by submitted claims.
