Description
Technical field
The present invention relates to a kind of magnetic coding lock core and magnetic coding padlock that can bear adverse circumstances.
Background technology
Padlock is a kind of common locking lockset, and its use has the history of nearly one thousand years.Since have simple in structure, easy to use, be easy to processing, characteristics such as certain weather resisteant arranged, so use very extensively, particularly environment uses more down out of doors.Such as, the normal operating mechanism that adopts padlock locking car door and outdoor equipment in rail transportation system; Be usually used in the locking container door on the water in the transportation system; In power system, be used for locking electrical control cubicles door and manual equipment operating mechanism etc.
In recent years, along with continuous progress in science and technology, transportation, electric power, chemical system develop very fast, and the quantity of equipment is how much rules and increases, and the padlock quantity that is used for interlock also significantly increases.Like this, padlock is so some defectives that have cause people's attention gradually, and these defectives are mainly reflected in weatherability and two aspects of controllability.Aspect weather resisteant, because the rain-proof structure imperfection, lock core, lock body, parts such as lock ring get rusty easily.Particularly maybe can produce under the environment of electrochemical reaction at ocean climate, acid rain weather, this phenomenon is more obvious.Generally, a padlock non-refuelling that adopts non-ferrous metal (as: copper, kirsite, aluminium alloys) to make can only be used 2-3.In addition, anti-dust indifferent.Common padlock has the hole of three straight-through lock body inside, and one is keyhole, two other is lock ring hole, and these three Kong Junwei adopt dustproof constructions.Under the strong sand and dust environment, dust is easy to enter lock body inside by these holes, causes the lockset clamping stagnation, lockset inside and keyhole thoroughly can be blocked when serious, can't unblank fully.
Because there is the defective of above-mentioned weatherability aspect in common padlock, thus out of doors under the environment spoilage higher, need constantly to change.This has increased use cost on the one hand, also may produce potential safety hazard simultaneously.Such as, in chemical industry or power system, the operation of equipment is to have strict flow process to require, and will produce great security incident not according to flow operations.And some manual equipments often adopt padlock to carry out locking, need during operation to open lockset by flow process, carry out the equipment operation then.Therefore, controlling the order of unblanking well just can control operating process well.Because this control mode is general as the technological means that prevents accident, so the reliability of lockset has been proposed high requirement with quilt.If in the operating process, lockset can't be opened, and flow operations will be forced to stop, thereby produces potential safety hazard.
Aspect controllability, because padlock adopts lock ring locking object, lockset need not to be fixed on by on the locking thing, so have characteristics easy to implement, easy to use.But this also brings the shortcoming that operator scheme is single, can not carry out electric control operation.Such as, when needing in above-mentioned chemical industry, the power system that lockset carried out flow operations, can only operate by the mode of artificial selection key, automaticity is lower, and therefore the phenomenon that the order of operation mistake might occur can not reach the requirement by flow operations fully.Again such as, under some industrial environments, need carry out entrance guard management to some outdoor facilities.But operation has used the lockset of identical code-locked to carry out locking in a large number for convenience, because padlock can not carry out automatically controlled and identification, also just can't realize control of authority.Like this, just can open all locks, not have the effect of entrance guard management at all in case the user of service takes a key.
Existing magnetic coding lock is to adopt the design of non-contact magnetic force conduction principle, and its list has magnetic, is generally bistable structure.List is in unlock position when opening lock; Be in the locking position after the locking.Specifically make list be in the locking position by the mutual exclusion of two carrying magnetic lists.After the key that has magnet entered unlocked position, one of them magnetic list was because of being subjected to the effect of two blocks of magnet simultaneously, and the position will change, thereby enter unlock position.The fatal shortcoming of this structure is that the magnetic list can quick loss of excitation under high temperature, vibrations, alternating electromagnetic field environment.The result who causes can't unblank or can be opened by other key.Therefore, the use amount of magnetic coding lock is less, and its technology also is a not too mature technique.
In sum, existing padlock has the following disadvantages: weatherability is poor, controllability is not high, the magnetic list can quick loss of excitation under high temperature, vibrations, alternating electromagnetic field environment.
