Abstract

A key buckle comprises a key ring adopting the structure that one end is larger than the other end; a hole on which a key can be hung is formed at the larger end of the key ring; a buckling hole is formed at the smaller end of the key ring; the key buckle further comprises a self-locking device which can be locked after the smaller end, where the buckling hole is formed, of the key ring is inserted in and can be pulled out conveniently; and an insertion hole allowing the smaller end of the key ring to be inserted in is formed on the self-locking device. When in use, the key buckle is hung in a place easy to see, such as the wall behind or beside a door; after a user arrives at home every time, all that is needed is to insert the smaller end of the key ring into the self-locking device, a buckle bulge can enter the buckling hole, so that the whole key buckle can be enabled to be hung on the self-locking device in a buckling manner, therefore, before going out each time, the user can clearly see the keys on the wall behind or beside the door, all that is needed is to press a pressing part of a pressing device, then the buckle bulge can come out of the buckling hole, and the key ring can fall out; and people can find keys on the wall behind or beside the door before going out each time, so that the circumstance can be avoided effectively that keys can not be found when being needed urgently.
