To achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of numeric keypad used convenient for blind person,
Including keyboard body and multiple keys being set on the keyboard body, the upper surface of each key be equipped with
The corresponding braille salient point of mathematic sign, the upper surface of the keyboard body upwardly extend multiple mounting bases, multiple described
Key, which corresponds, to be detachably arranged in the mounting base.
The lower end of the key is provided with a cavity, and the centre of the cavity is fixed with a pillar extended downwardly,
The pillar has a downwardly open cavity, and the left and right sides of the pillar is symmetrically offered to be connected to the cavity
Mounting groove, be fixed with Elastic buckle in the mounting groove, offered on two inner sidewall of left and right of the mounting base
With the card slot of the resilient snap fitment, the Elastic buckle, which corresponds, to be fastened in the card slot.In the structure,
The setting of pillar hollow cavity inwardly squeezes convenient for Elastic buckle, provides a space for Elastic buckle, Elastic buckle and
Card slot matches, and is on the one hand convenient for key fast assembling-disassembling, is being on the other hand that key and mounting base are fixed between the two.
The Elastic buckle is made of fixed part and pothook, and the lower end of the fixed part is fixed on the installation
In slot, the pothook is fixed on the top of the fixed part, and is located at the outside of the fixed part.In the structure,
Fixed part is made of plastics for fixing with mounting groove, has certain elasticity, the setting of pothook is then convenient for solid with card slot
It is fixed.
The pillar is in tetragonous rod structure.It is advantageous in that overall structure is more firm.
The reinforcing rib being distributed vertically is respectively fixed on two inner sidewall of front and back of the cavity.In the structure, reinforcing rib
Setting strengthen the integral strength of pillar.
The left and right sides of the mounting base upper end extends outwardly respectively is provided with guide holder, setting in the guide holder
There is the guide groove slid into for the Elastic buckle.In the structure, guide groove is located at the upper end of mounting base, slides into Elastic buckle
It when into mounting base, is matched first with guide groove, plays the role of pre-determined bit, guide groove is intilted oblique with one
Face, Elastic buckle slide into mounting base along guide groove, then snap onto card slot again, and it is more convenient to operate.
The upper end of the key has an arc-shaped concave, and the braille salient point is arranged on the arc-shaped concave.
In the structure, the setting of arc-shaped concave improves comfort level when user uses.
Four corners of the keyboard body lower end are fixed with non-slip mat.
Compared with the prior art, the advantages of the utility model are: by the way that braille salient point, each key are arranged on key
On braille salient point correspond to different numbers, in this way convenient for blind person input password, reduce blind person use obstacle；Key and mounting base
Removably connect, it is also more convenient when overhauling, while installing convenient for the subsequent key to damage；This is practical new
Type can guarantee the normal use of blind person, and be conveniently replaceable key.
