Description

Lock with magnetic control mother lock beads

The invention relates to a lock, in particular to a lock design of a magnetic control sub-locking bead which combines a mother-locking bead technology and a magnetic inner core magnetic control technology.

The conventional lock structure is composed of a lock case, a lock core, a plurality of upper lock beads, a lower lock bead and a spring. The lock case and the lock core are provided with one or a plurality of rows of corresponding plurality of lock bead holes. A locking bead, a lower locking bead and a spring are implanted in the locking bead hole, and the staggered arrangement structure of the locking bead and the lower locking bead of each group is used, and the tension of the spring causes the end of the lower locking bead to protrude in the keyhole. The lock must be properly opened with a matching toothed key. If an inconsistent key is used to try to twist, the locking bead or the lower locking bead will be locked between the locking case and the rotating surface of the lock, resulting in the lock. Can not turn, that is, the lock cannot be opened.

Since the above-mentioned locks cause the end of the lower locking bead to protrude in the keyhole, the thief can use a push rod and a tweezing tool to spit or push the lower locking bead, thereby twisting the locking core to open the locking device. It is obvious that the safety mechanism of such locks is not good enough to prevent thieves. To this end, the invention of the case has been proposed to design a variety of magnetic lock beads, such as the Republic of China Announcement No. 459875, the hidden magnetic lock bead lock lock, the anti-theft lock lock with invisible magnetic lock bead shown in Announcement No. 448960, and the magnetic safety lock shown in Announcement No. M306259. Among them, only one of the magnetic lock beads of No. 448960 is placed in the hole of the lock bead, so it is easy to be cracked. The magnetic lock beads of No. 448960 are arranged by using a plurality of locking beads with different positive and negative poles, and the magnetic poles of the magnets on the key must cooperate with each other to push the locking beads, but the magnetic poles have only positive and negative poles, even if a plurality of magnetic locking beads are arranged, Still easy to be cracked. In the magnetic lock bead of No. M306259, the magnet on the key must be magnetically correct to push the magnetic lock bead to the correct position, so it is difficult to realize and the cost is high.

The object of the present invention is to provide a lock with a magnetic control sub-locking bead, which is designed to be more precise and difficult to be opened by the design of the magnetic control sub-locking bead and the use of other types of locking beads. .

In order to achieve the above object, a preferred technical content of the present invention includes a lock case having a lock core hole and a first outer bead hole radially communicating with the lock core hole; a lock cylinder penetrating the lock core hole, having an axial key hole, and a first inner bead hole radially communicating with the key hole and the first outer bead hole; a first outer tube a bead, which is disposed in the first outer bead hole, has a first outer bead hole, the first outer bead hole has a neck portion; a first inner bead is placed on the first bead An inner bead having a pair of first inner bead holes that should be the first outer bead hole; An outer core bead is disposed in the first outer core bead, and opposite to the end of the lock core, has a limiting rod that passes through the neck portion into the first outer bead hole; a magnetic inner core bead Inserted in the first inner core bead; the first outer bead abuts against one end of the first inner bead and moves between an open position and a locked position, and the first outer core The bead abuts against one end of the magnetic inner bead and moves between an open position and a locked position.

According to the above preferred technical content, the magnetic control sub-locking beads a locking device, wherein the neck portion of the first outer core bead defines a necking hole and an axial stopping surface, the limiting rod having a diameter smaller than the first outer core and passing through the necking hole to enter the first Outer bead hole.
