A locking pin includes a body having a plurality of apertures defined through a sidewall. A closure is disposed at an end of the body. A plurality of latch bolts is disposed in the body and adjacent to the closure. Each latch bolt is moveable through a corresponding one of the apertures and between a locked position, disposed at least partially outside of the body, and an unlocked position, disposed at least substantially within the body. A keeper is coupled to each of the latch bolts and configured to retain the latch bolt in the latched position and to bias the latch bolt for movement from the locked position to the unlocked position. A mechanism selectably engages each latch bolt to move the latch bolt to the locked position, and selectably disengages from the latch bolt to allow the keeper to move the latch bolt to the unlocked position.

A cooking appliance includes a casing having a cavity therein, and a door opening and closing the cavity. In addition, a door locking device disposed in the casing catches the door to turn the door into a locked state.
