Description

Improved notebook key support structure

Technical field

The utility model relates to a kind of improved notebook key support structure, and particularly a kind of notebook that is applicable to can make supporting structure be easy to assembling in specific direction, and at the direction of the application of force key support structure of difficult drop-off again.

Background technology

Consult notebook key support structure known among Fig. 1, it comprises a keycap 80, elasticity shake-up body 81, one first support 82, one second support 83 and a pedestal 84 and constitutes, this first support 82 and second support, 83 both sides center sections are provided with corresponding rotating shaft 86 and axis hole 87 articulates mutually, make this two stands 82 and 83 be articulated into cross-like, and be connected to pedestal 84 with this two stands 82 and 83 lower ending pivots, this two stands 82 and 83 upper ends then are linked to keycap 80 bottom surfaces, form a bridge formation mechanism with this two stands 82 and 83.This elasticity is touched body 81 and is positioned between the stroke of keycap 80 starts, it is parallel up and down when mobile that this keycap 80 is done by two stands 82,83 guiding, the elasticity of these keycap 80 belows is touched the FPC 85 that body 81 could press or leave the below, the action that makes switch open or close.

Above-mentioned known notebook press-key structure, the axis hole 87 of its second support 83 when rotating shaft 86 length of first support 82 are long, are difficult for assembling for circular hole designs; When rotating shaft 86 length of first support 82 more in short-term, be easy to again come off, so the inconvenience that causes two stands 82,83 when assembling, to produce.

Consult another kind of known notebook press-key structure among Fig. 2, it comprises that mainly first support 82 ' and second support, 83 ' both sides center sections are provided with corresponding axis hole 87 ' and rotating shaft 86 ' articulates mutually, and this axis hole 87 ' adopts the holes design, more or less freely in the time of so can making the rotating shaft 86 ' of second support 83 ' be assembled in the axis hole 87 ' of first support 82 ', use the problem that solves the assembling difficulty.But because this axis hole 87 ' adopts holes design, its broken hole position forms permeable type, and rotating shaft 86 ' is as easy as rolling off a log deviates from axis hole 87 ' by broken hole position, therefore still has the defective that is easy to come off.

As from the foregoing, above-mentioned known notebook key support on reality is used, obviously has inconvenience and exists with disappearance, need make improvements.

In view of the deficiency that existing notebook key support exists, the utility model proposes a kind of reasonable in design and effectively improve the notebook key support of above-mentioned deficiency.

Summary of the invention

Fundamental purpose of the present utility model, be to provide a kind of improved notebook key support structure, it can make key support be easy to assembling in specific direction, and rotating shaft and axis hole are assembled the problem that has difficulties mutually when assembling to solve, and at application of force direction difficult drop-off.

To achieve these goals, the utility model provides a kind of improved notebook key support structure, and this structure comprises: one first support, and its both sides center section respectively is provided with a rotating shaft; And one second support, its both sides center section respectively is provided with an axis hole, and this two axis holes sidewall part offers holes, and this two axis holes sidewall part has wall, the holes that second support is passed in two rotating shafts of this first support is assembled in two axis holes, makes two rotating shafts be positioned two wall inboards.

In order further to understand technical characterictic of the present utility model and technology contents, below in conjunction with accompanying drawing the utility model is elaborated, yet accompanying drawing only provides reference and explanation, be not in order to restriction the utility model.

Embodiment

Consult Fig. 3, Fig. 4 and Fig. 5, the utility model provides a kind of notebook key support structure that has improved, especially refer to a kind of notebook that is applicable to, can be arranged at the bridge formation mechanism between keycap and the pedestal, this supporting structure comprises one first support 10 and one second support 20, wherein this first support 10 is an Openworks shape support body (see figure 3), and body can be touched for ccontaining elasticity in its inside.These first support both sides, 10 upper end and lower end are respectively equipped with

coupling shaft

11 and 12, make these first support, 10 upper ends and lower end be linked to keycap 30 (see figure 6)s and pedestal (figure slightly) by

coupling shaft

11 and 12 respectively.These first support, 10 both sides center sections respectively are provided with a rotating shaft 13, and these two rotating shafts 13 protrude in first support, 10 both sides outer rims 14.

This second support 20 also forms an Openworks shape support body (as Fig. 4), and the width of this second support 20 makes second support, 20 inside ccontaining elasticity touch the body and first support 10 greater than the width of first support 10.These second support both sides, 20 upper end and both sides, lower end are respectively equipped with

coupling shaft

21 and 22, make these second support, 20 upper ends and lower end be linked to keycap 30 (as Fig. 6) and pedestal (figure slightly) by

coupling shaft

21 and 22 respectively.These second support, 20 both sides center sections respectively be provided with one with rotating shaft 13 corresponding axis holes 23, this two axis hole 23 laterally runs through second support, 20 both sides inner edges 24 and outer rim 25.

The utility model mainly respectively offers a holes 26 in these two axis holes, 23 sidewalls, this holes 26 is opened in axis hole 23 adjacent sidewalls inner edges 24 places, axis hole 23 sidewalls are had only in abutting connection with inner edge 24 places formation permeable type, these axis hole 23 adjacent sidewalls outer rims 25 places then can not form permeable type, still have suitable wall 27 these axis hole 23 sidewalls of sealing.

This first support 10 and second support 20 are to utilize corresponding rotating shaft 13 and axis hole 23 to articulate into the bridge formation mechanism (Fig. 5, Fig. 6) that cross-like is provided with.Done by two stands 10,20 guiding parallel up and down when mobile when keycap 30, and the elasticity of keycap 30 belows is touched the FPC (figure slightly) that body (figure slightly) could press or leave the below, makes switch open or close action; By constituting improved notebook key support structure of the present utility model above-mentioned the composition.

The utility model has increased the design of a holes 26 on the axis hole 23 of second support 20, be assembled in the axis hole 23 after making the rotating shaft 13 of first support 10 can pass holes 26, more or less freely when making the rotating shaft 13 of first support 10 be assembled in the axis hole 23 of second support 20, so bridge formation mechanism is easy to assembling in specific direction (as the direction A of Fig. 5), uses the problem that solves the assembling difficulty.

In addition, because axis hole 23 adjacent sidewalls outer rims 25 places do not form permeable type, still have suitable wall 27 these axis hole 23 sidewalls of sealing, make in the axis hole 23 of the wall that is positioned second support 20 27 inboards that the rotating shaft 13 of the support 10 of winning still can be firm, therefore at application of force direction (as the direction B of Fig. 6) difficult drop-off.

The above is the utility model preferred embodiment only, is not meant to limit protection domain of the present utility model, so the equivalent structure that all utilization the utility model instructionss and accompanying drawing content are caused changes, all in like manner is contained in the utility model scope.
