Description
Technical field
The present invention relates to a kind of theftproof lock, be different from common on the market blade lock and cylinder lock, the marking lock that the present invention is a kind of new structure.
Background technology
Existing mechanical anti-theft lock, according to its lock core principle difference, can be divided into cylinder lock, blade lock, magnetic lock.
Cylinder lock is a kind of modal lock structure.Its principle is several holes that radially distributing on the cylinder-type lock wicking surface of billiards structure, these holes are corresponding with the hole on lock body, and ensure necessary concentricity. in these holes, pack two rows straight pin into, go up pellet and lower pellet. generally, upper pellet in lock body opening inserts in lock core hole, or lower pellet in lock core inserts in lock body opening, lock core can not be rotated arbitrarily. after key inserts, due to key bit apart from marble hole one by one corresponding tooth depth and lower spring length corresponding, thereby the contact surface of pellet and lower pellet is just in time coincided with the contact surface of lock core and lock body, lock core therefore can rotate freely, lead agency is realized switch motion.
Cylinder lock comes out existing more than 150 year so far, at present still in extensive use, is more common on the market a kind of lockset.But just, due to the extensive utilization of cylinder lock technology, the drawback of cylinder lock is also more and more obvious, main manifestations the following aspects: one, pellet end expose and impulse stroke short, pellet can directly be touched by foreign matter (steel wire hook etc.), easily by technical opening; Two, non-lock key all can enter lock core, easily causes by means of key and opens mutually and key tooth not etc. does not leave etc. mutually.Oneself key can enter others' family lock, and what have even can also drive others' family's lock;
three,key can arbitrarily be prepared, and can find on the market the people of bitting everywhere.Four,, a little less than anti-technical opening, common experienced locksmith or burglar, set up tinfoil and just can easily open the door the key mould of cylinder lock with one.Or adopt " hitting spoon " method, even also can easily open the door without the people of the training of unblanking after knowing method, do not set up defences only not.
Magnetic lock is to utilize the permanent magnet two like magnetic poles repel each other principle that there is a natural attraction between the sexes, thereby provide a kind of and replace the metal pellet in commercially available cylinder lock with slip permanent magnet, use " key " with permanent magnet, by means of key magnet with lock in sliding magnet repel each other or mutually inhale, lock is opened or closed.Because this lock is without keyhole, avoid the shortcoming of cylinder lock completely; In addition, magnet is enclosed in lock or key completely, and their arrangement situation be can't see in outside, so this lock has stronger disguise; Because this lock is without lockhole and rotatable parts, it is more easily accepted by disabled person and children again.
But magnetic lock but has a huge defect, is not durable exactly, this lockset magnetic on the key, can disappear along with service time, and the time, longer demagnetization phenomenon was more obvious, and finally becoming the disappeared key of magnetic of major part can open mutually between various locksets.And the keeping of magnetic lock key is also problem, if key storage is improper, suffering gravity collision or run into high temperature all can demagnetization.Once demagnetization, lock has not just been opened.
Another kind of modal lock structure is exactly blade lock, and its principle is exactly to utilize on the key bevel angle to change different tartars to rotate angle in alignment lock core and change different blades, thereby realizes the one lock that lock core rotarily opens.Blade lock is a kind of lockset that current safety factor is higher, but its complex structure, ubiquity processing, assembling complexity, packaging efficiency is low, high in cost of production problem.
Certain theftproof lock is on the market not only that these are several, and kind is a lot, and as compound lock, so-called compound lock refers to that the lock core of two or more different principle is combined in to same handle to be locked.The anti-theft capability of theftproof lock is mainly its lock core structure, and structure is more complicated, and its anti-technical opening ability is better, but also just when the river rises the boat goes up for corresponding cost.So general more expensive theftproof lock anti-theft capability is better, but expensive price has stoped user's desire to purchase exactly, and the thousands of price of hundreds of is not often among user's consideration.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of theftproof lock of new structure, be different from the structure of main flow lock core, anti-technical opening ability is strong, and production technology is simple, and cost is lower.Because its supporting key is cylinder, key end face can be designed to unique marking or pattern, therefore called after marking lock.
