ABSTRACT:
Disclosed is a sliding mechanism for opening and closing a cellular phone. The mechanism includes a main plate, a slider plate slidably connected to the main plate, a first block shaft-rotatably fixed to the main plate, one or more first rod member fixed to the first block, a first resilient member connected to the first block and generating expansion force, a second block shaft-rotatably fixed to the slider plate, one or more second rod member fixed to the second block, a second resilient member connected to the second rod member and generating expansion force, and a connection block placed in the central area of the first and second blocks and supporting the end portions of the first and second resilient members. The connection block slidably connects the first and second rod members with the first and second blocks in such a way that the end portion of the first rod member is directed towards the second block and the end portion of the second rod member is directed towards the first block. The first and second resilient members are formed of a compression spring having a good resiliency and service life, thereby improving reliability of cellular phones.
