mount pad

5, 6 end fixing of removal post has arc dog 7, be fixed with on the removal post 6 and keep off the dish 8, keep off and be connected with first spring 9 between dish 8 and the 5 inner walls of mount pad, be fixed with on the mount pad 5 and adjust seat 10, be equipped with inclined plane 11 on adjusting the seat 10, be fixed with on inclined plane 11 with barb portion 15 complex joint spare 12.

The other end of the elastic element 14 is fixedly connected with a mounting ring 13, and the mounting ring 13 is fixedly mounted at the bottom of the keyboard shell 1 through a fixing bolt and a gasket.

The clamping piece 12 comprises an inclined part which is fixed on the inclined surface 11 and used for driving the elastic part 14 to deform towards the outside, and a clamping hook part which is arranged at the end part of the inclined part and matched with the barb part 15, and the clamping piece 12 is fixed on the inclined surface 11 at equal intervals.

When the use inclination angle needs to be adjusted, one end (the right side in fig. 1) of the keyboard housing 1 far away from the connecting seat 3 is pressed downwards. In the pressing process, the barb portions 15 are matched with the inclined portions on the clamping pieces 12, the elastic pieces 14 can deform outwards, and then the barb portions 15 can be continuously downwards matched with the clamping hook portions on the clamping pieces 12 in the pressing process in a clamping mode.

When adjusting suitable use inclination, stop pressing keyboard casing 1 can, this moment under the elastic force effect of first spring 9, remove post 6 and give keyboard casing 1 ascending power through arc dog 7, and barb portion 15 and the cooperation of the hook portion on the joint spare 12 can prevent keyboard casing 1 and upwards rotate, and then realize using the regulation at inclination fixed.

The inclined surface 11 is provided with a return mechanism for driving the elastic member 14 to return to the original position, and the return mechanism comprises a barrier strip 16 fixed on one side of the clamping member 12 and tightly attached to the barb portion 15, and an arc portion 17 arranged at the bottom of the barrier strip 16 and bent towards one side of the clamping member 12.

As shown in fig. 3, when the usage inclination is adjusted, the side surface of the barb 15 is always attached to the left side of the barrier strip 16 when the barb 15 is engaged with the hook of each clip 12. The keyboard housing 1 is continuously pressed, and when the barb portion 15 is separated from the hook portion on the bottommost snap member 12, i.e. acts with the curved portion 17, the elastic member 14 is deflected.

When the barb part 15 moves to the bottommost part of the curved part 17, the keyboard housing 1 is released, and the keyboard housing 1 rotates upwards under the elastic force of the first spring 9, and the barb part 15 moves to the right side of the barrier strip 16. After the barb part 15 completely moves to the top of the barrier strip 16, the elastic part 14 returns to the original state, drives the barb part 15 to move to the left side of the barrier strip 16 again, and drives the elastic part 14 to return to the original position.

The keyboard comprises a keyboard shell 1 and is characterized in that a circuit board 18 is arranged inside the keyboard shell 1, an active spring piece 21 and a fixed spring piece 22 which are matched with each other are connected onto the circuit board 18, a shaft core 23 is connected onto the keyboard shell 1 in a sliding mode, a blocking piece 27 located between the active spring piece 21 and the fixed spring piece 22 is fixed onto the shaft core 23, a shaft seat 19 is fixed onto the keyboard shell 1, a shaft cover 20 is fixedly connected onto the shaft seat 19, and a clamping column 28 extending out of the shaft cover 20 and used for clamping a keycap is fixed to the top of the shaft core 23.

The top of the keyboard shell 1 is provided with a first through hole matched with the shaft core 23, and the baffle 24 is provided with a second through hole and a third through hole respectively matched with the driving spring piece 21 and the fixed spring piece 22.

The keyboard shell 1 is internally provided with a key stroke adjusting mechanism for adjusting the stroke distance of the shaft core 23, and the key stroke adjusting mechanism comprises a movable baffle plate 24 arranged in the keyboard shell 1, a mounting column 25 fixed on the baffle plate 24 and connected with the shaft core 23 in a sliding manner, and a second spring 26 connected between the shaft core 23 and the baffle plate 24.

A positioning member 30 extending out of the side of the keyboard housing 1 is relatively fixed on the side of the baffle plate 24, a fourth through hole 29 matched with the positioning member 30 in an up-and-down movement manner is formed in the side of the keyboard housing 1, an adjusting bolt 31 is connected to the side of the keyboard housing 1 in a threaded manner, and a sliding hole 32 matched with the adjusting bolt 31 is formed in the positioning member 30.

When the key stroke of the key needs to be adjusted, the baffle plate 24 is driven by the positioning part 30 to move along the vertical direction, and after the proper position is adjusted, the adjusting bolt 31 is screwed down to fix the positioning part 30.

When the baffle plate 24 moves upwards, the shaft core 23 moves upwards under the action of the elastic force of the second spring 26, so that the key stroke is lengthened, and meanwhile, as the baffle plate 27 moves upwards along with the shaft core 23 and the compression amount of the second spring 26 is increased, the key pressing force also needs to be increased; when the baffle plate 24 moves downwards, the shaft core 23 moves downwards under the action of the elastic force of the second spring 26, so that the key stroke is shortened, and simultaneously, the blocking piece 27 moves downwards along with the shaft core 23, and the compression amount of the second spring 26 is reduced, so that the key pressing force is weakened.

In the technical scheme of the application, the positioning element 30 and the fourth through hole 29 are matched to further play a limiting role, so that the baffle 24 can move along a straight line, and the baffle 24 is prevented from losing response to the driving spring piece 21 and the fixed spring piece 22, which results in key failure. In addition, a limiting block can be fixed on the shaft core 23, and when the keyboard is pressed, the limiting block is matched with the upper surface of the keyboard shell 1 to control the limit position of the downward movement of the shaft core 23.
