Embodiment
For that can further appreciate that the feature of the utility model, technological means and the specific purposes reached, function, below
The utility model is described in further detail with embodiment with reference to attached drawing.
As shown in figures 1-6, the utility model discloses a kind of press-key structure, including upper cover 2, base 3 and button axle
101, button axle 101 includes dust-proof axis 1, little spring 5 and axle center 6, and dust-proof 1 active card of axis is in upper cover 2, on the base 3
Equipped with through through hole 9, axle center 6 is equipped with via hole 8, and 6 top of axle center is equipped with blind hole 7, and attaching little spring 5 in dust-proof axis 1, this is small
The lower part of spring 5 is installed in the blind hole 7 in axle center 6 and is connected with axle center, and the top of little spring 5 is interior mounted in dust-proof axis 1 and engages company
Connect, big spring 11 is set with axle center 6, axle center 6 is actively plugged in through hole 9, and upper cover 2 clamps on the base 3, axle center 6
In the installation space formed between the upper cover and base, the lower end of big spring 11 rest against 3 upper surface of base；Push dust-proof
The axle center, which produces rotation, while drive axle center moves down during axis makes axle center lower part lead to from the bottom surface for being pierced by base through through hole
Cross and two radially-protruding fixture blocks are set on the top in axle center, using the fixture block, by setting a thimble inside dust-proof axis,
Thimble extruding fixture block pushes little spring at the same time when dust-proof axis pushes so that axle center moves down while rotation.Set in dust-proof axis
There is fore-set, which is sleeved on the fore-set upper and lower part and is placed in the blind hole in axle center.When not pushing dust-proof axis, dust-proof axis
Top is exposed outside upper cover.
The bottom surface of the base 3 is equipped with the through hole circle wall 10 being located at through 9 side of through hole, is symmetrically set on the through hole circle wall 10
There are two open slot positions 12.Through hole circle wall is an integral molding structure with base.It is again provided with being located in the upper surface of base and passes through
The circle wall of reach through hole side, big spring are sleeved on the circle wall, ensure the good location of big spring.
The center that base end face is arranged on through through hole.
In addition, the outer surface of upper cover 2 is equipped with convex mirror 4.Pass through the convex mirror, when button is installed on keyboard, keyboard
The light that interior light produces runs into the convex mirror, so as to have more preferable condenser effect, produces more preferable lighting effects.
The base, upper cover, dust-proof axis and axle center are made by plastic material, i.e., whole button is plastic products, tool
There is more preferable portability.
The invention also discloses another technical solution, a kind of keyboard, including it is above-described some by bond
Structure, the press-key structure are installed on the input operation part point that keyboard is formed on keyboard.
In the utility model, by button be installed on keyboard in, button conducting by be located on keyboard to pipe signal lamp
The signal of generation produces.One signal projector and signal receiver are respectively usually set in the both sides in axle center.When not operating, prevent
Dirt axis is exposed outside upper cover, and axle center is not stretched out from through through hole at this time, and the lower part in axle center is through through hole and through hole circle wall
Interior, the signal that signal projector is sent is blocked to pass through by axle center lower part and received by signal receiver, and button is in not at this time
Conducting state, as shown in attached drawing 1 and 4.When needing operation button, dust-proof axis is pressed, dust-proof axial depression enters in upper cover, on dust-proof axis
The little spring of attaching is subject to down force pressure and shrinks, and continuous with dust-proof axis pushes, and drives axle center to move down, axle center is downward
Rotation is produced while mobile, during axle center moves down, big spring is compressed.Axle center is from through through hole and through hole circle
It is pierced by wall, the via hole on axle center is exposed in the open slot position of through hole circle wall, is now placed in the signal transmitting of button side
The signal of device transmitting can be from the via hole that the open slot position of through hole circle wall enters axle center, then is pierced by from via hole another to axle center
It is received in the signal receiver of side, so as to form the conducting of signal, button turns at this time, can complete to input, such as the institute of attached drawing 5
Show.
Since axle center can be pierced by from base when the utility model pushes, conducting film mechanism is could be applicable to, is pushed
Being pierced by the axle center of base can contact with conducting film, and pressure is formed to conducting film so that conducting film is led with other mechanism contacts
It is logical, expand the application range of button.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, it is still
It can modify to the technical solution described in previous embodiment, or equivalent substitution is carried out to which part technical characteristic,
But where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should be included in
Within the scope of protection of the utility model.
