The anti-theft lock further comprises a plurality of transmission rods which are matched, a plurality of sliding stop pieces, a plurality of pushing preventing pieces, a push rod, a connecting rod, a pushing rod and an auxiliary locking dog, so that the problems that an existing lock is low in safety and can not prevent people from opening the lock through unlocking technology are solved.
Description
Technical field
The utility model belongs to field of lockset, relates in particular to a kind of theftproof lock that is applicable to various security doors.
Background technology
At present, most locksets are by lock core, pellet, spring, dead bolt, the parts such as key form, adopt of opening ways dialled top formula unlatching more, this kind of lockset is due to a long history, the person of unblanking is to grasp its method for unlocking completely, how can adopt special tool(s) twisting internal cylinder, after the pellet in internal cylinder is upwards stirred successively, by means of the terrace between interior outer lock core, make internal cylinder pellet cannot head into outer lock core, and outer lock core pellet hinders outside internal cylinder, thereby lockset is opened, simple and easy due to the universal of technology and operation, the safety of traditional lockset can not meet people's theft-proof requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of theftproof lock, solves existing lockset degree of safety low, can not prevent that people from using the problem of unlocking technique pirate of the open.
For achieving the above object, the technical solution of the utility model is: a kind of theftproof lock, comprise lock body, be arranged on the master lock tongue of lock body inside, be provided with for stirring the plectrum of master lock tongue motion on described master lock tongue, lock body inside is provided with interior anti-lock device and interior opening device, on lock body, be provided with the keyhole that can not rotate and the bull stick that is 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 being passed to slide, stop sheet;
Some slips stop sheet, be slidably mounted on lock body inside, slide and stop the bottom of sheet one side end face to be provided with recess, top is provided with limiting tooth limit, described each slides and stops the height and position of sheet recess inconsistent, slide and stop sheet bottom to be connected with drive link one end, slide and stop sheet bottom to be provided with the back-moving spring for return;
Some anti-plectrums, top is coaxially arranged on lock body inside, and described anti-plectrum lower end one side is provided with and the teeth of sliding and stoping the limiting tooth limit on sheet to coordinate;
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 secondary lock tongue matches with the recess of the prevention sheet that slides.
Described poke rod is sleeved on bull stick by the through hole at poke rod middle part, and described through hole is provided with location stroke, for allowing bull stick not drive poke rod to rotate LAP.
When key inserts after keyhole of the present utility model, each drive link passes to corresponding slip by corresponding key teeth height and stops sheet, stop sheet recess to be adjusted to same level the different slip of original height, now by the handle being connected with bull stick, rotate bull stick, first, the driving lever being fixedly connected with on bull stick embeds the teeth of anti-plectrum to slide by connecting rod and stops in the limiting tooth limit of sheet, thereby stop sheet to be fixed slip, because the middle through-hole of poke rod is provided with location stroke, so stop in the process of sheet fixing slip, poke rod does not rotate, be rotated further bull stick, bull stick just drives poke rod motion, the secondary lock tongue of poke rod lower end just in time inserts the slip of being fixed by anti-plectrum to be stoped in the recess of sheet, due to entering of secondary lock tongue, poke rod drift angle is strengthened, poke rod upper end drives master lock tongue to move by the plectrum on master lock tongue, thereby master lock tongue is return, complete and open lockset overall process.The effect of the anti-plectrum in this process is that the person that prevents technical opening dials top drive link with instrument and makes some slips stop the recess level on sheets unanimously to complete the process of in the past opening lockset, change the method that conventional art is opened lockset, thereby realized the function that prevents technical opening.
The utility model lockset does not have the structures such as pellet, rim lock cylinder, and simultaneously keyhole maintains static, and is provided with dial-proof device, thereby the lockset that has overcome existing cylinder lock core can not prevent from using unlocking technique to open the problem of lockset.
