Embodiment
As shown in Figure 1, it is the Facad structure synoptic diagram of two groups of keyboard module of the present utility model, and the right and left of each keyboard module 1 all has three draw-in grooves 2, and Open Side Down for draw-in groove 2, and the size of opening can enter fin 6 (Fig. 3), and fin 6 is moved up and down within it.As shown in Figure 2, then be the reverse side structural representation of keyboard module of the present utility model, have the trapezoidal profiled holes 3 of two symmetries at the back side of keyboard module 1, be useful on the metal pin 4 of signal exchange at the top.
As shown in Figure 3, it is the utility model graphing calculator shell structure synoptic diagram; On the corresponding position of the left and right sides of graphing calculator housing (hereinafter to be referred as " housing ") 5 and draw-in groove 2, be equipped with three fins 6 that cooperate with draw-in groove 2, on housing 5, be provided be used for fixing keyboard module 1 cooperate with profiled holes 3 can movable fin 8.In addition with the housing 5 of metal pin 4 corresponding positions on be provided with connector 7, left-right symmetric is provided with two spring leafs on the connector next door.
As shown in Figure 4, it is the utility model blocking device structural representation.Wherein Fig. 4 a is a latch structure synoptic diagram of the present utility model, and latch presents the U type, and it comprises two symmetrical fins 8 on top, the spring compression portion 10 at middle part and the control movable end 9 of bottom.Fig. 4 b is a framed structure synoptic diagram of the present utility model, and framework 11 is fixed on the housing 5, and in the one side spring 12 is housed.Fig. 4 c is the blocking device after the assembling, blocking device comprises U type latch, framework 11 and pressing plate 13, pressing plate 13 is fixed on the framework 11 by four screws 14, can certainly directly be fixed on the housing 5, U type latch is sandwiched in the middle of framework 11 and the pressing plate 13 in addition, can do side-to-side movement along framework 11, and be overstock by spring 12 dextrad of framework 11.In addition, shown in accompanying drawing 5a, this moment, the control movable end 9 of latch passed the back side that housing 5 is positioned at graphing calculator.
As shown in Figure 5, it is the utility model keyboard module and housing assembling synoptic diagram.In Fig. 5 b, a keyboard module 1 snaps onto in the housing 5 in fin 6 positions that its draw-in groove 2 is aimed at housing 5, because fin 6 can move forward and backward in draw-in groove 2, be pushed forward into keyboard module 1 this moment, when being pushed into metal pin 4 and having touched connector 7 fully, the fin 8 of housing 5 has snapped onto in the profiled holes 3 of keyboard module 1.This moment since fin 6 be stuck in the draw-in groove 2 can't be up and down and move left and right, and fin 8 snaps onto profiled holes 3 and can't move forward and backward, keyboard module 1 just has been fixed in the housing 5 like this.
When changing keyboard module 1, at first, shown in Fig. 5 a, move the control movable end 9 of the latch at the back side that is positioned at graphing calculator, make fin 8 break away from profiled holes 3, at this moment, two spring leafs 9 that are provided with on the position, connector 7 next door of housing 5 can force keyboard module 1 to move backward, when fin 6 moves to the aperture position of draw-in groove 2, just can take off keyboard module 1 and change.
As shown in Figure 6, it is two groups of keyboard module dresses of the utility model back synoptic diagram.Select different keyboard module 1 according to different demands, housing 5 is then fixed.
