Magnetic lock

Abstract

The invention discloses a magnetic lock. A lock core of the magnetic lock is characterized in that one end of a nonmagnetic rod is vertically connected with a magnetic conducting plate after sequentially penetrating through a nonmagnetic spacing plate and a pressure spring, while the other end of the nonmagnetic rod is equipped with a buckle hook; a plurality of permanent magnets are assembled on the other end surface of the magnetic conducting plate, opposite to the nonmagnetic rod; the nonmagnetic spacing plate is connected with an upper nonmagnetic plate, a lower nonmagnetic plate, a front nonmagnetic plate and a back nonmagnetic plate to form a cuboid cavity; the upper end surface, the lower end surface, the front end surface and the back end surface of the magnetic conducting plate are slidingly matched with the inner wall of the cuboid cavity; the end surfaces of the permanent magnets, in contact with the magnetic conducting plate, are one magnetic poles of the permanent magnets; and another nonmagnetic spacing plate is arranged opposite to the other magnetic poles of the permanent magnets, and is connected with each nonmagnetic plate to form key holes. A fastener mechanism with a lock hook, a clip hook and a spring is connected with the upper nonmagnetic plate; and the clip hook can be clamped and connected with the buckle hook of the nonmagnetic rod. The lock core and the fastener mechanism are both connected with a lock shell. Another magnetic conducting plate is assembled with permanent magnets as many as the permanent magnets of the lock core to form a key, wherein the same polarities of the permanent magnets on the another magnetic conducting plate and the permanent magnets of the lock core are opposite.

Description

technical field [0001] The invention relates to lock technology, in particular to a magnetic lock. Background technique [0002] Existing locksets are divided into mechanical locks and electronic locks. Most of the mechanical locks are tumbler locks, and electronic locks include face recognition or fingerprint recognition induction locks, electronic combination locks, and photoelectric electronic locks. To tumbler lock, needn't be the key that it matches, and with some illegal master key or opening tool, also can open in a short period of time (within 50 minutes), so technical (non-destructive) anti-theft performance is poor. Electronic locks, although technically better in anti-theft performance, have circuits and electronic devices inside, need continuous power supply, and some have to remember passwords, so it is inconvenient to use, and their anti-destructive and environmental adaptability are not as good as tumbler locks.

Problems solved by technology

For the tumbler lock, it can be opened in a short period of time (within 50 minutes) by using some illegal master keys or opening tools without matching the key, so the technical (non-destructive) anti-theft performance is poor

Electronic locks, although technically better in anti-theft performance, have circuits and electronic devices inside, need continuous power supply, and some have to remember passwords, so it is inconvenient to use, and its anti-damage and environmental adaptability are not as good as tumbler locks.
