Abstract
A screen pin-typed pickproof lock comprises a lock body, a lock core, a lock tongue and a poke tablet, wherein the lock body and the lock tongue are the same to a present general lockset, and is characterized in that the lock core comprises a stator and a rotor, wherein in the radical direction of the inner cylinder surface of the stator at least two screen pins are arranged, in which a conical snap hole is arranged and the rotor comprises a key hole, a cylinder pin, a snap pin, a fixed axle, a gemel and a torsional spring, wherein the outer cylinder plane of the rotor are provided with at least two open slots, the number of which is the same as the number of the screen pins; above the key hole at least two cylinder pin holes are arranged, the number of which are the same as the number of the screen pins; a cylinder pin is arranged inside the cylinder hole, and the cylinder pin is articulated with the snap pin; the torsional spring is arranged in the gemel; the snap pin is connected with the rotor through the fixed axle and the rotor is connected with the lock body through a poke tablet. The utility model has the advantages of simple structure, high safety, low production cost and convenient application and the lock core of the lock is suitable for the production of a plurality of locks and built-in locks.
Description
Technical field
The utility model relates to a kind of lockset, and what be specifically related to is a kind of screens pin formula pick-proof lock.
Background technology
As everyone knows, lockset is that people are used for avoiding theft, a kind of instrument of protection property safety.But present general lockset is easy to stolen person and utilizes simple tool to open, and safety factor is extremely low; And cipher lock cost height not only, and cumbersome when using, be unfavorable for common applications.
Summary of the invention
The purpose of this utility model provide cost rationally, vi have high safety, can extensive use a kind of screens pin formula pick-proof lock.
The technical scheme that adopts is:
A kind of screens pin formula pick-proof lock, comprise lock body, lock core, dead bolt, plectrum, lock body is identical with existing general lockset with dead bolt, it is characterized in that lock core comprises stator, rotor, radially have two screens pins at least at the stator inner cylinder face, the taper stop hole is arranged on the screens pin, rotor comprises keyhole, straight pin, latch, fixed axis, hinge, the torsion spring, radially have two open slots on the external cylindrical surface at rotor place at least, open slot quantity is consistent with the screens pin, have two cylinder pin holes above keyhole at least, cylinder pin hole quantity is consistent with the screens pin, and cylindrical hole is equipped with straight pin, straight pin and latch are connected through the hinge, dispose the torsion spring on the hinge, latch links to each other with rotor by fixed axis, and rotor joins by plectrum and lock body.
Operating principle is: in the time of in key inserts keyhole, straight pin moves up, and drives latch by hinge and moves, and latch does not just in time enter in the open slot this moment, and rotor is just free to rotate, realizes moving of dead bolt thereby drive plectrum, realizes unlocking function.When other key inserts keyhole, straight pin moves up and moves by hinge drive latch, latch enters in the open slot at this moment, and behind the rotor rotation certain angle, latch enters stop hole, because stop hole is a bellmouth, by the rotation of rotor, latch is stuck in stop hole, rotor can't rotate, therefore just do not drive the rotation of plectrum, just can't open lock.Because the stopping function of stop hole, picklock just can not play a role, and has realized the pick-proof effect.
Advantage of the present utility model is: simple in structure, safety performance is good, low cost of manufacture, and it is convenient to use, and the lock core of this lock is suitable for making various bright, built-in locks.
