Self-matching locks and keys

The invention relates to a key and a lock core, in particular to a lockable key and a key which can be easily changed by the user to change the combination of the lock core and can effectively increase the combination of the lock core and the key arrangement.

The locks of the prior art have various forms, one of which is the most common one is a pin lock. The basic structure of the pin lock is to provide a lock core on the outer casing, and the lock core comprises a lock case, a lock core and a plurality of lock beads.

The lock case has a cylindrical shape and a receiving space is formed at a central portion thereof, and a plurality of outer locking bead holes are formed on a side wall surface of the lock case, and the lock body is cylindrical and a key hole is formed in the center. A plurality of inner locking bead holes are disposed on one side of the outer wall surface of the locking arm, and the inner locking bead holes penetrate through a side wall surface of the key hole, and the locking arm is rotatably disposed in the locking case, the locking case The locking bead holes are sequentially aligned with respect to the outer locking bead holes.

The locking bead set includes an outer locking bead, an inner locking bead and an elastic member. The locking bead set is respectively disposed in the corresponding outer locking bead hole and the inner locking bead hole, and the outer locking bead and the elastic member are located outside In the locking bead hole, the elastic member is pushed up at the outer end of the outer locking bead, so that the inner end of the outer locking bead is slightly protruded in the inner locking bead hole, and the inner locking bead is located in the inner locking bead hole. The outer end of the locking bead and the inner end of the outer locking bead abut each other, so that the inner end of the inner locking bead moves out of the key hole, wherein the length of the locking bead and the inner locking bead of each locking bead group corresponds to Key to the key, the key is inserted in the keyhole Afterwards, each of the key teeth is pushed against the corresponding inner locking beads, so that the inner locking bead and the outer locking bead move to the boundary where the two opposite ends are located at the inner wall surface of the locking case and the outer wall surface of the lock core, so that the key can be locked by the key The lock is rotated relative to the lock case, thereby achieving the purpose of unlocking.

However, in the lock structure of the prior art, each specific length of the lock bead can only correspond to the key arrangement of a key. When the user installs multiple locks in the life, the user must hold more than one. The key is not only space-consuming but also has the inconvenience of finding a key. It is difficult to distinguish the appearance of the key. When the key is lost, the same key must be remade with the parent key, otherwise the lock must be replaced. If the user loses the key, the lock can be used to prevent the key picker from entering theft, which is not only inconvenient, but also cost a lot of money and time, so the prior art marble lock can still be improved.

Therefore, in order to effectively solve the above problems, the main object of the present invention is to provide a lockable key and a key that can be easily matched by the user to change the combination of the lock core and can effectively increase the combination of the lock core and the key arrangement.

In order to achieve the above object, the present invention provides a self-matching lock core and a key, comprising: a lock core and a key, wherein the lock core has a lock core shell, a plurality of lock shell rings and a plurality of lock cylinders. The lock core has a channel therein and a slot is formed on one side of the channel, and at least one first positioning post and at least one second positioning post respectively protrude from the two ends of the lock core shell, and the lock shell ring system is disposed A locking ring ring positioning post protrudes from the slot and is formed with at least one marking mark on the side of each of the locking ring rings, and the locking ring rings are fixed to the chassis via a positioning member. The lock core is disposed in the lock case ring respectively, and the key has a grip, a stem and a plurality of unlocking blocks, and the grip is screwed through a pair of seats Group of the core An external threaded portion of one end of the column, wherein the unlocking blocks are respectively formed with a set of holes, and the sleeve is sleeved on the stem, and each of the unlocking blocks is formed with at least one pair of symbols and a The side protrusions have a top portion of different heights, whereby the lock case ring can be directly removed through the positioning member, and is removed by the slot to facilitate changing the arrangement thereof, and through the lock case The marking symbol on the ring should be used to unlock the block to effectively increase the combination of its lock and key.
