[embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Please cooperate with reference to Fig. 2 to Fig. 3, Fig. 2 is the schematic perspective view of LED high definition display screen of the present utility model; Fig. 3 is the perspective exploded view of LED high definition display screen shown in Figure 2.This LED high definition display screen 2 comprises a drive plate 21 and a display screen 22.This drive plate 21 is fixed on this display screen 22, and is 90 degree settings with this display screen 22.Described moving plate 21 comprises a first surface 210, one and the fixing gap 218 of these first surface 210 opposing second surface 211, a plurality of chip for driving 212, a plurality of pin 216 and two location gap 214 and four.These a plurality of chips 212 are arranged on this first surface 210.These a plurality of pins 216 are arranged on this first surface 210 and second surface 211 its lower edge, and the output terminal of the drive signal of these a plurality of chip for driving 212 of conduct.These two location gap 214 also are positioned at the lower edge of this drive plate 21, and curved structure also runs through this drive plate 21.These four fixedly gap 218 be symmetricly set on the both sides of the edge of this drive plate 21, and these both sides of the edge are vertical with the lower edge of this drive plate 21.Fixedly gap 218 also is the arcuate structure of indent and runs through this drive plate 21.

Described display screen 22 comprises the mat woven of fine bamboo strips four surfaces (not indicating) and a fixed slot 222 on one the 3rd surface 220, relative the 3rd surface 220.This fixed slot 222 is arranged on the 3rd surface 220, and the 4th surface is provided with many group LED lamp groups (figure does not show), is used for display message.This fixed slot 222 comprises fixedly buckle 230 of a slot 224, two fixed legs 225 and two.These two fixed legs 225 are separately positioned on the two ends of this slot 224.Each fixedly buckle 230 be arranged on the side of this fixed leg 225 away from this slot 224.And, each fixedly buckle 230 by a columniform fixed pin 231 and be arranged on this fixedly buckle 230 cooperate fixing near the through hole 234 of bottoms.This slot 224 comprises a plurality of contact pins 226 and two register pins 228.The surface that is arranged on these 224 liang of inboards of slot of these a plurality of contact pin 226 symmetries, and it has certain elasticity.These two register pins 228 are arranged in this slot 224 corresponding to two location gap 214 of this drive plate 21.

Described each fixed leg 225 comprises the column 227 of two L-shaped structures, and the column 227 of these two " L " shapes is oppositely arranged and form a gap in the middle of both at this, as shown in Figure 3.In these drive plate 21 these slots 224 of insertion, the column 227 of these two L-shaped structures can prevent that this drive plate 21 from swinging.Fixedly buckle 230 is for the inner hollow structure and comprise a clamping part 232, a junction 235 and a boss 238 that sets gradually from the top to the bottom for each, and this connecting portion 235 connects this clamping part 232 and this boss 238.This connecting portion 235 comprises two depressed parts 236.The shape complementarity of the column 227 of the shape of these two depressed parts 236 and these two " L " shapes, as shown in Figure 2.These two fixedly buckle 230 can this fixed pin 231 be the axle center rotating certain angle.When these two fixedly buckle 230 turn to certain angle to the direction of these two fixed legs 225 respectively, each fixedly two depressed parts 236 of buckle 230 overlap complementary respectively with the column 227 of two " L " shapes of each fixed leg 225.

When this LED high definition display screen 2 of assembling, at first, the register pin 228 of the location gap 214 of this drive plate 21 being aimed at this display screen 22 also firmly inserts this drive plate 21 in this slot 224.These a plurality of contact pins 226 are owing to having elasticity, so can clamp the pin 216 of this drive plate 21 securely.This location gap 214 is fixed with cooperating of this register pin 228 and can be prevented from this drive plate 21 is inserted in this slot 224 with the direction of mistake.Have only should locate gap 214 could be after aiming at this register pin 228 with this drive plate 21 these slots 224 of insertion.Then these two fixed legs 225 that fixedly buckle 230 is corresponding with it are respectively closed up, at this moment, be positioned at this fixedly the depressed part 236 of buckle 230 both sides overlap with the column 227 of corresponding " L " shape respectively.Simultaneously, these two fixedly the clamping part 232 of buckle 230 withhold corresponding fixedly gap 218, the fixedly gap 218 of this correspondence is near these drive plate 21 tops.Adopt this buckle mode, increase this drive plate 21 and these display screen 22 reliability of fixation.Thereby the first surface 210 that is positioned at this drive plate 21 has been realized reliable contact with the pin 216 of second surface 211 with the pin 226 that contacts that is positioned at these 224 liang of inboards of slot.When connecting external power source (figure does not show), this drive plate 21 drives these display screen 22 display message.

When needs are dismantled this drive plate 21, with this two fixedly buckle 230 firmly break into two with one's hands to direction away from the fixed leg 225 of correspondence, simultaneously, since be positioned at this fixedly the boss 238 of buckle 230 bottoms can produce an acting force that makes progress simultaneously, and then make this drive plate 21 can be pulled out this slot 224 smoothly.

The drive plate 21 of the utility model LED high definition display screen 2 directly inserts in the slot 224 of this display screen 22, the pin 216 of this drive plate 21 contacts with the pin 226 that contacts of these slot 224 inboards, and this contact pin 226 has certain elasticity can clamp this pin 216 more securely.Not only convenient, also time saving and energy saving when assembling or dismantling this drive plate 21 with this display screen 22.On the other hand, these two the fixing fixedly gap 218 of these drive plates 21 of buckle 230 engaging, further very high this drive plate 21 and these display screen 22 reliability of fixation, no matter central still in the middle of the clear display screen 2 of this LED merchant of transportation in use, this drive plate 21 is not easy to become flexible with the interface of this display screen 22, has promoted the interface fastness of this LED high definition display screen 2.The drive plate 21 of this LED high definition display screen 2 is 90 with this display screen 22 at last.Be provided with, the heat energy distribution when having accelerated a plurality of LED lamp groups work of this a plurality of chip for driving 212 and this, and then improved the radiating efficiency of this LED high definition display screen 2.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
