In order to achieve the above purpose, the utility model adopts the following technical scheme:

a key board of an old people machine is designed, which comprises a shell, a key board is fixedly arranged at the top end of the shell, a plurality of key blocks are arranged on the key board, the key blocks all penetrate through the key board, and is connected with the key-press disk in a sliding way, the bottom of each key-press block is provided with a pressing mechanism which comprises a pressing block, the pressing blocks are fixedly connected with the corresponding key blocks, the bottom ends of the pressing blocks are sleeved with rubber sleeves, the pressing block is connected with the rubber sleeve in a sliding way, a first supporting sheet is arranged in the rubber sleeve in a sliding way, the top end of the first supporting sheet is contacted with the pressing block, the bottom of the first supporting sheet is fixedly provided with a return spring, the bottom end of the return spring is fixedly connected with a second supporting sheet, the second supporting sheet is connected with the rubber sleeve in a sliding mode, and a metal sheet is fixedly installed at the bottom of the second supporting sheet.

Preferably, a circuit main board is arranged below the metal sheet, the circuit main board is fixedly installed inside the shell, and the top area of the circuit main board corresponds to the key pad.

Preferably, a plurality of conductive blocks are fixedly mounted at the top of the circuit main board, and the conductive blocks are in contact with the corresponding metal sheets.

Preferably, a corresponding waterproof protection pad is fixedly installed between the key block and the key disc.

The utility model provides a pair of keypad of old machine, beneficial effect lies in: the utility model discloses a pressing mechanism's design, the effect lies in, after the user pressed the button piece, and first supporting plate acts on the answer spring for answer the spring and become compression state, after loosening the button piece, the elasticity of answer spring can make the button piece resume original state, and this has just avoided the button piece sunken in the keyboard, makes the cell-phone facilitate the use more.

Drawings

Fig. 1 is a schematic structural view of a key board of an old people machine according to the present invention;

fig. 2 is a schematic view of a partial structure of a key board of an old people machine according to the present invention;

fig. 3 is a schematic view of an internal structure of a key board of the elderly people machine according to the present invention;

fig. 4 is the utility model provides a press mechanism's of keypad of old machine structural schematic.

In the figure: the key comprises a shell 1, a key block 2, a key panel 3, a circuit board 4, a conductive block 41, a pressing mechanism 5, a pressing block 51, a rubber sleeve 52, a first supporting sheet 53, a return spring 54, a second supporting sheet 55 and a metal sheet 56.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

referring to fig. 1-4, a key board of an old people machine comprises a shell 1, a key board 3 is fixedly installed at the top end of the shell 1, a plurality of key blocks 2 are installed on the key board 3, the key blocks 2 all penetrate through the key board 3 and are in sliding connection with the key board 3, and corresponding waterproof protection pads are fixedly installed between the key blocks 2 and the key board 3; the waterproof protective pad can prevent water from entering the interior of the keypad 3, thereby damaging the internal electronic components of the mobile phone.
