To achieve the above object, the utility model adopts the following technical scheme is: a kind of mechanical keyboard press-key structure, packet Keying body is included, several described keying bodies are detachably located on keyboard, and conductive film, the key sheet are equipped in the keyboard Body includes keycap, central spindle, inner shaft, spring, elastic slice and pedestal, and the pedestal is located in keyboard, and the central spindle engages company with pedestal It connects and passes through spring elastic spacing movement in pedestal, the elastic slice is located in pedestal and connect with the side elastic of central spindle, institute It states keycap to be detachably set in central spindle, the inner shaft is located in central spindle, and the inner shaft is when central spindle moves down and conductive film Be electrically connected, when reset with conductive UF membrane.

Preferably, the side of the pedestal is equipped with limited mouth, and the top of the limited mouth is equipped with middle plate, and the middle plate is upper Positive stop end, the bottom surface of the pedestal are lower limit end, and pillar is equipped in the pedestal, through-hole is equipped in the pillar and is convenient for inner shaft It passes through.

Preferably, the top of the central spindle is equipped with slot, and the fixed column with interior axis connection is equipped in the lower part of the central spindle, The lower side of the central spindle is equipped with Elastic buckle, and the central spindle engages to connect with pedestal with limited mouth by Elastic buckle It connects.

Preferably, one end of the spring is set on pillar, and the other end of the spring, which supports, to be located in central spindle.

Preferably, further include circuit board, luminescent screen and bottom plate in the keyboard, the circuit board, luminescent screen and bottom plate according to It is secondary to be located at below conductive film.

The utility model has the beneficial effects that: mechanical switch is substituted using central spindle, it is not necessary that central spindle is straight with electrical behavior switch It connects in succession, electrical transmitting can be carried out by inner shaft and the point contact of conductive film, abrasion can be reduced using purely mechanic axle construction, prolonged Long life, and structure is simple, reduces production cost, replacement central spindle is convenient.
