Embodiment
In order to describe structure of the present utility model, feature and effect place in detail, lift following preferred embodiment now and cooperate graphic explanation as after.
See also Fig. 1 and Fig. 2, be the display device 10 that the utility model one preferred embodiment is provided, include a display screen 20, a bonnet 30, a bracing frame 40 and a circuit board assembly 50.
The bottom at display screen 20 back sides has two first location divisions 22, and each first location division 22 is a shank; The left and right sides of display screen 20 back side central authorities has one second location division 24 respectively, and each second location division 24 is a cramp, and the side edge of display screen 20 in contiguous each second location division 24 is provided with a guide rail 25; The top at display screen 20 back sides has two the 3rd location divisions 26, and each the 3rd location division 26 is a guide rail; In addition, display screen 20 has two first joint portions 28 between this these the 3rd location division 26, and each first joint portion 28 is the perforation of an ovalize, and display screen 20 has two in the top of this these first joint portion 28 and colludes groove 282.
The top of bonnet 30 leading flanks has two second joint portions 32, and each second joint portion 32 is a shank, can pass first joint portion 28 (perforation) of display screen 20; Bonnet 30 has two trips 34 in the top of this these second joint portion 32, but hook colluding in the groove 282 in display screen 20.
The front end of circuit board assembly 50 has two the 3rd joint portions 52, and each the 3rd joint portion 52 is the perforation of an ovalize; The rear and front end on limit, circuit board assembly 50 left and right sides has one the 7th location division 54a respectively, 54b, each the 7th location division 54a, 54b is a guide rail, and each the 7th location division 54a, the surface of 54b is provided with two salient points 56, the salient point 56 that is positioned at the 7th location division 54a of front end can tightly fit in the 3rd location division 26 (guide rail) of display screen 20, the salient point 56 that is positioned at the 7th location division 54b of rear end then can tightly fit in the 6th location division 46 (guide rail) of bracing frame 40, make circuit board assembly 50 can by these these salient points 56 with these these the 3rd, the 6th location division 26, friction force between 46 the surface and being located between display screen 20 and the bonnet 30; And when circuit board assembly 50 was positioned between display screen 20 and the bonnet 30, each the 3rd joint portion 52 (perforation) of circuit board assembly 50 was communicated with first joint portion 28 (perforation) of display screen 20 just and can be worn by second joint portion 32 (shank) of bonnet 30.
In the time will assembling display device 10 of the present utility model, earlier these these guide rail 25 butts of display screen 20 limit, two opposite sides of bracing frame 40 and along the limit, two opposite sides of bracing frame 40 toward interior promotion, first location division 22 (shank) of display screen 20 is embedded in the 4th location division 42 (guide groove) of bracing frame 40, and second location division 24 (cramp) that makes display screen 20 fastens the 5th location division 44 of bracing frame 40, thus, as shown in Figure 3, display screen 20 can't produce up and down and the moving of left and right directions relative to bonnet 30.Then the limit, two opposite sides of circuit board assembly 50 is slipped between display screen 20 and the bonnet 30 along the 3rd location division 26 (guide rail) of display screen 20 and the 6th location division 46 (guide rail) of bracing frame 40, and the surface, the 6th location division 46 (guide rail) of surface, the 3rd location division 26 (guide rail) of the salient point 56 packing display screens 20 of the 7th location division 54 by circuit board assembly 50 and bracing frame 40, can't move left and right in order to restricting circuits plate assembly 50, as shown in Figs. 4-6.Last pivot by bracing frame 40 again forces bonnet 30 close towards display screen 20, as shown in Figure 7, pass the 3rd joint portion 52 (perforation) of circuit board assembly 50 and first joint portion 28 (perforation) of display screen 20 up to second joint portion 32 (shank) of bonnet 30, and trip 34 hooks of bonnet 30 are colluded in the groove 282 in display screen 20, promptly finish assembling operation of the present utility model.
In the time of circuit board assembly 50 will being disassembled when wanting repair circuit plate assembly 50, what force earlier that the trip 34 of bonnet 30 breaks away from display screens 20 colludes groove 282, and the display screen 20 that pivots simultaneously, make first joint portion 28 (perforation) of the 3rd joint portion 52 (perforation) and display screen 20 of second joint portion 32 (shank) the breaking circuit plate assembly 50 of bonnet 30, so that display screen 20 is separated with bonnet 30.Then the application of force is twitched circuit board assembly 50, because circuit board assembly 50 is to fix with display screen 20 and bracing frame 40 by the friction force between the surface, the 6th location division 46 (guide rail) of (guide rail) surface, the 3rd location division 26 of the salient point 56 of the 7th location division 54 and display screen 20 and bracing frame 40, therefore, the user does not need to expend very big strength and can overcome this friction force and smoothly circuit board assembly 50 is detached between display screen 20 and the bonnet 30, in order to the action of conveniently keeping in repair.
Thus, display device of the present utility model does not use the assembling that any screw is promptly finished all members, during circuit board assembly, also do not need to use any instrument in dismounting, can increase the convenience of assembly and disassembly operation really and reach the purpose of this utility model.
The utility model is taken off disclosed composed component among the embodiment in preceding, only for illustrating, is not the scope that is used for limiting this case, the alternative or variation of other equivalence element, and the claim that also should be this case contains.
