Key assembly and ultrasonic diagnostic system control panel assembly

The present invention discloses a control panel assembly and the key assembly of an ultrasound diagnostic system, the key assembly includes a key, a first carrier and a second connector connecting frame; the key mechanism is provided with a plurality of slots; said first connection frame and the second frame are shaped structure is connected; a first connecting member and second connecting two side frame portions are provided with a cylindrical configuration cooperating with said socket means; said first connection frame the two side portions is provided with a circular hole structure is provided with a cylindrical structure with the circular projections of the two cooperating side edge portions of the second connector frame. The key component of the first connecting member and the second coupling frame is mounted by fitting a cylindrical projection and the circular hole structure, the first and second connecting frame rotatable relative to the connecting frame, and through the slot means and the cylindrical structure when mounted with the keys and the first connecting member, a second connecting frame with vertical movement, the height of the space may be small, the pressing still provide a key, key entire downward movement will effectively solve the card key The problem.
