Abstract
The object of the present invention is to provide a kind of theftproof lock, comprise lock body, be arranged on the master lock tongue of lock body inside, described master lock tongue is provided with the plectrum for stirring the motion of master lock tongue, lock body inside is provided with interior anti-lock device and interior opening device, lock body is provided with the keyhole that can not rotate and the bull stick being provided with back-moving spring, described bull stick one end mounting knob, also comprise the some drive links cooperatively interacted, some slip blocking tab, some anti-plectrums, a driving lever, a connecting rod, a poke rod, it is low that secondary lock tongue solves existing lockset degree of safety, can not prevent people from using the problem of unlocking technique pirate of the open.
Description
Technical field
The invention belongs to field of lockset, particularly relate to a kind of theftproof lock being applicable to various security door.
Background technology
At present, most lockset is by lock core, pellet, spring, dead bolt, the parts compositions such as key, the many employings of opening ways are dialled top formula and are opened, this kind of lockset is due to a long history, the person of unblanking is to grasp its method for unlocking completely, special tool(s) how can be adopted to twist internal cylinder, after the pellet in internal cylinder is upwards stirred successively, by means of the terrace between interior outer lock core, internal cylinder pellet is made to head into outer lock core, and outer lock core pellet hinders outside internal cylinder, thus lockset is opened, simple and easy due to the universal of technology and operation, the safety of traditional lockset can not meet the theft-proof requirement of people.
Summary of the invention
The object of the present invention is to provide a kind of theftproof lock, solve existing lockset degree of safety low, can not prevent people from using the problem of unlocking technique pirate of the open.
For achieving the above object, technical scheme of the present invention is: a kind of theftproof lock, comprise lock body, be arranged on the master lock tongue of lock body inside, described master lock tongue is provided with the plectrum for stirring the motion of master lock tongue, lock body inside is provided with interior anti-lock device and interior opening device, lock body is provided with the keyhole that can not rotate and the bull stick being provided with back-moving spring, described bull stick one end mounting knob, also comprises
Some drive links, are coaxially arranged on lock body inside, for the height of key teeth is passed to slip blocking tab;
Some slip blocking tab, be slidably mounted on lock body inside, the bottom of slip blocking tab one side end face is provided with recess, top is provided with limiting tooth limit, the height and position of described each slip blocking tab recess is inconsistent, be connected with drive link one end bottom slip blocking tab, bottom slip blocking tab, be provided with the back-moving spring for return;
Some anti-plectrums, top is coaxially arranged on lock body inside, and described side, anti-plectrum lower end is provided with the teeth coordinated with the limiting tooth limit of sliding in blocking tab;
A driving lever, described driving lever is fixedly mounted on bull stick;
A connecting rod, one end is connected with driving lever, and the other end is provided with some springs, and described spring is connected with the teeth opposite side of anti-plectrum;
A poke rod, is arranged on bull stick, and upper end is flexibly connected with master lock tongue, and lower end is flexibly connected with secondary lock tongue, and the upper end of described poke rod is used for stirring master lock tongue plectrum;
A secondary lock tongue, is slidably mounted on lock body inside, is flexibly connected with poke rod lower end, and the recess of secondary lock tongue and slip blocking tab matches.
Described poke rod is sleeved on bull stick by the through hole in the middle part of poke rod, and described through hole is provided with location stroke, does not drive poke rod to rotate LAP for allowing bull stick.
After key inserts keyhole of the present invention, the key teeth height of correspondence is passed to blocking tab of sliding accordingly by each drive link, the different slip blocking tab recess of home position height is adjusted to same level, handle now by being connected with bull stick rotates bull stick, first, the teeth of anti-plectrum embed in the limiting tooth limit of slip blocking tab by connecting rod by the driving lever that bull stick is fixedly connected with, thus slip blocking tab is fixed, middle through-hole due to poke rod is provided with location stroke, so in the process of fixing slip blocking tab, poke rod does not rotate, be rotated further bull stick, bull stick just drives poke rod to move, the secondary lock tongue of poke rod lower end just in time inserts in the recess of the slip blocking tab of being fixed by anti-plectrum, due to entering of secondary lock tongue, poke rod drift angle is strengthened, poke rod upper end drives the motion of master lock tongue by the plectrum on master lock tongue, thus master lock tongue is return, complete and open lockset overall process.The effect of the anti-plectrum in this process is that preventing techniques opener uses instrument to dial top drive link to make the recess level in some slip blocking tab unanimously carry out to open the process of lockset in the past, change the method that conventional art opens lockset, thus realize the function of preventing techniques unlatching.
Lockset of the present invention does not have the structure such as pellet, rim lock cylinder, and keyhole maintains static simultaneously, and is provided with dial-proof device, thus the lockset overcoming existing cylinder lock core can not prevent from using unlocking technique to open the problem of lockset.
