Bead locked-type security antitheft lock

Abstract

The invention discloses a bead locked-type security antitheft lock, which comprises a lock body and a key, wherein the key is provided with an unlocking magnetic block, the lock body is provided with a lock rod, one end of the lock rod extends out of the lock body, the other end is divided into a plurality of ends, the lock body is also provided with a bead passage, the lower end of the bead passage is provided with a bead original position, magnetic beads are arranged on the bead original fixed position, at least one side of the bead passage is also provided with a bead antilock fixed position and a bead unlocking fixed position, and the plurality of ends of the lock rod respectively extend to the corresponding bead original fixed position and the bead antitheft fixed position. When in unlocking operation, the unlocking magnetic block on the key drives the magnetic beads to slide along the bead passage until the magnetic beads are brought to the bead unlocking fixed position, so the plurality of ends of the lock rod can pass through the corresponding bead original fixed position and the bead antitheft fixed position, the lock rod is moved, and the unlocking is realized; if the thief makes mistake to bring beads to the bead antitheft fixed position through the key magnetic block, the corresponding ends of the lock rod is blocked, so the lock rod cannot move, and good antithefteffect can be realized; therefore, the entire operation is simple and easy, and the antitheft effect is good.

Description

technical field [0001] The invention relates to the technical field of anti-theft locks, in particular to a glass bead locking type safety anti-theft lock which can obviously improve the anti-theft effect. Background technique [0002] On the market, traditional anti-theft locks can be divided into mechanical anti-theft locks and electronic anti-theft locks according to their locking and unlocking principles; however, both mechanical anti-theft locks and electronic anti-theft locks have the following shortcomings (1) Although mechanical locks have certain advantages in anti-theft, their complex structure, complex operation, and high manufacturing cost are not conducive to the popularization and application of products; and electronic anti-theft locks, their cost is higher, and their circuits are complicated , It is easy to be disturbed in anti-theft, and the anti-theft effect is also uneven. Therefore, people long for always, can design one and have simple in structure, rea...
