Abstract
The utility model relates to a kind of Special keyboard for computer teaching, rectangular housing is placed with several button assemblies according to keyboard layout, spiral jump ring is being provided with between the T-shaped end and the upper inner wall of rectangular housing of upper end, LED light-emitting substrate is provided with in the middle part level of the inner chamber of rectangular housing, be provided with mirror reflective plate in the side edge tilt of the bottom of rectangular housing, the position corresponding to mirror reflective plate, the opposite side edge in the bottom of described rectangular housing are provided with keyboard map panel.The utility model uses the principle of light reflection, and when people presses the key mapping of specifying, relative button axle will move down, and the intensity of its printing opacity and size will change slightly, finally play the effect of the key mapping at display button place, have practical value.
Description
Technical field
The utility model relates to a kind of Special keyboard for computer teaching.
Background technology
In known technical field, computor-keyboard is the passage the control information of Word message input computer, and coming from the differentiation of english typewriter keyboard, is one of part and parcel in computer peripheral equipment accessory.In traditional computer teaching, a lot of operations of computing machine all need to have been come by keyboard, need to carry out being familiar with of key mapping to keyboard, in education activities, due to keyboard structure singularity, good demonstration cannot be carried out on classroom, thus need a kind of can easy, the method for efficiently carrying out keyboard teaching.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides a kind of Special keyboard for computer teaching.
The utility model solves the technical scheme that its technical matters adopts: a kind of Special keyboard for computer teaching, there is the rectangular housing of hollow, in described rectangular housing, described rectangular housing is placed with several button assemblies according to keyboard layout, each button assembly has button axle, upper at described button axle, lower two ends are equipped with T-shaped end, spiral jump ring is being provided with between the T-shaped end and the upper inner wall of rectangular housing of upper end, described spiral jump ring is big top and small bottom, and its one end is embedded in the upper inner wall of rectangular housing, the other end blocks the sidewall of button axle, transparent plastic ring is coated with in the T-shaped end being positioned at lower end, LED light-emitting substrate is provided with in the middle part level of the inner chamber of described rectangular housing, mirror reflective plate is provided with in the side edge tilt of the bottom of described rectangular housing, corresponding to the position of mirror reflective plate, keyboard map panel is provided with at the opposite side edge of the bottom of described rectangular housing, described keyboard map panel is provided with corresponding key mapping viewing area according to keyboard layout.
Further, consider the steadiness of structure, the utility model is provided with hold-down support in the bottom of described mirror reflective plate and keyboard map panel.
Further, in order to emphasis demonstrates the change after light reflection, the utility model is coated with fluorescent material layer in each key mapping viewing area.
Further, consider button axle reset after spacing problem, the coboundary of the utility model in the T-shaped end of the lower end of described button axle and transparent plastic interannular are provided with spacing chamfering.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, fully use the principle of light reflection cleverly, when people presses the key mapping of specifying, relative button axle will move down, thus make the T-shaped end being positioned at lower end depart from transparent plastic ring, be mapped on keyboard map panel due to after the light active refraction that LED light-emitting substrate will send by otherwise transparent plastic hoop, after This move, the intensity of its printing opacity and size will change slightly, thus final keyboard map panel is changed, finally play the effect of the key mapping at display button place, meticulously ingenious, has practical value, in the process of button axle backhaul, coordinate spiral jump ring, spacing chamfering will limit it and moves up further and complete reset.
Accompanying drawing explanation
