DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0003]
  There are many types of flat key locks, but the basic structure of the flat key and lock body is a pairAnd the function and handlingSimilarly, a key lock body that can be locked and unlocked with one type of flat key is a pair of key lock bodies.Imitation and duplication of authentic flat keyUnusual unlocking doors are opened by othersThere is also a thingIn addition, because the keyhole is set in the horizontal direction on the front side of the door with a wide front space and a person can insert a flat key with an upright natural posture, an abnormal solution caused by unauthorized equipment other than the unlocking door with a true flat key There can also be a lock door opening.
[0004]
  The present invention replaces a flat key with a solid three-dimensional key with a precise structure.DoneEasy imitation duplication is prevented, and a hook effect member is added to the clasp, and the keyhole position is set to the vertical axis on the lower side of the round handle that narrows the keyhole position so that a three-dimensional key is inserted from the bottom surface direction. It makes it difficult to look directly into the keyhole and to insert unauthorized appliances, and serves to prevent abnormal unlocking and opening of doors.
