Abstract

The invention relates to the field of interphones, in particular to an interphone for an elevator wireless intercom system, which comprises a mounting plate, a video intercom unit arranged on the mounting plate, a connecting unit arranged on the video intercom unit and a safety unit arranged on the connecting unit. Under the action that the inclined surface I and the clamping groove are matched with the inclined surface III and the clamping surface, the video interphone is locked and unlocked in the mounting groove, so that a passenger can conveniently take down the video interphone, take down the video interphone, hold the video interphone by hand and move the video interphone to the side of the mouth for conversation and directly close the microphone to a sound source when an emergency occurs. And the pickup distance is shortened to 5-10cm from fixed 0.5-1m, so that the problem of voice blurring caused by long distance and noisy environment of the traditional fixed interphone is avoided, and the accurate transmission of help seeking information is ensured.
