Abstract

The anti-theft lock core technical scheme that this illegal insertion just locks is: the function of built-in lock pin pellet is divided into work pellet and anti-theft billiards two class.Setting and the existing anti-theft lock core of work pellet are as good as.The setting of anti-theft billiards, make it often organize pellet and combine between the higher and lower levels a position all at inner key cylinder outer place, corresponding to it, the some position of key, outputs the circular hole that can hold pellet termination, and there is the gradient of convenient turnover in pellet hole Zhou Dynasty face.This lock key inserts, and anti-theft billiards slips in key preset holes, original invariant position, does not affect lockset and uses.Illegal thing inserts, and anti-theft billiards will inevitably be made to be shifted, and in part wedging lock core body, makes lock form lock-out state.Deft design, easy to make, technology is original, and effect is remarkable, particularly has unique preventive effect to tinfoil theft unlocking technique.

Description

The anti-theft lock core that illegal insertion just locks

1, technical field

The utility model relates to a kind of lock core of lock.

2, background technology

At present, what use amount was maximum is the various mechanical anti-theft locksets using pellet technology to manufacture, and its principle is the rotation being controlled inner key cylinder by the position of built-in pellet.After supporting key inserts lockhole, the pellet jack-up of touching key, often organizes position, upper and lower pellet abutment, and all at inner key cylinder outer place, twisting key can reach unlatching or locking effect.After key is extracted, pellet is under the strength effect of built-in spring, and two ends are inserted in lock core body and inner core respectively, makes the two be connected as a single entity, and inner core is limited to rotate.This theftproof lock, concerning common people, cannot open.But concerning the offender specializing in burglary, be but hard to guard against.Although theftproof lock in these years develops into so-called super B (C) type by A type Type B, the lockholes such as cross, plate, selenodont and key moulding also occur in succession, although add certain difficulty, and not new breakthrough in key technology.The unlocking technique that adjoint and raw master key, tinfoil etc. are new, is all threaten the property safety of people constantly.Utilize unlocking technique burglary to become a serious social concern, the stable society of creating policy needs a kind of lock that effectively can prevent pirate of the open badly.Naturally have many warm-hearted peoples, have devised various so-called robber jinx's lock.Let us not go into the question now, and whether it is effective resemble publicity, but often because of the complexity of its structure, the height of manufacture craft requirement, that drops in advance is huge, allows people hang back, is difficult to practice and extension effectively.

3, summary of the invention

Effectively can not prevent pirate of the open for solving existing anti-theft technique, the utility model provides a kind of anti-theft lock core of technological innovation, when not changing existing lockset lock core structure, material and technique, can greatly improve and strengthen the theftproof performance of this type of lockset.Technical solution adopted in the utility model is: the function and efficacy of built-in lock pin pellet is divided into two classes, is set to two kinds of different states (Fig. 1).A part is work pellet, and it arranges and is as good as with existing anti-theft lock, and its function is the normal use of responsible theftproof lock and has certain anti-theft function.Another part is anti-theft billiards, and sole duty tackles illegally to be unblanked.This part pellet is set to, its position, upper and lower abutment at inner key cylinder outer place, some position on the key corresponding to it, output the circular hole (Fig. 4) that can hold pellet termination, circular hole, towards the position, front and back of pellet one side, is processed into the gradient as key front end, to facilitate turnover lockhole.When this lock key uses, anti-theft billiards slips in the existing preset holes of key, is still original state, can not affect the normal use (Fig. 2) of lockset.And when lockset meets with pirate of the open, it just plays a role.We know, any pirate of the open, no matter are master keys, or tinfoil is unblanked, and all object used of unblanking must be inserted in keyhole and could realize.Once the keyhole having illegal object to insert the utility model lock core, will inevitably to touch, the anti-theft billiards extruded in lock core, make this kind of pellet change original state, be shifted, in part wedging lock core body, form lock-out state (Fig. 3).The tinfoil pirate of the open instrument that current burglar commonly uses, is exactly that one and key size dimension are suitable, wraps up in the steel disc of tinfoil thereon.It is once insert in this kind of lock, and scleroid steel disc must make anti-theft billiards be shifted and lock.Thus, the anti-theft lock of the illegal insertion that the utility model provides just locking, be one easy to make, technology is original, and effect is invented significantly, has unique preventive effect to tinfoil unlocking technique.

The anti-theft lock that this illegal insertion just locks, its practicality, validity are apparent.Meanwhile, its structure and existing anti-theft lock also completely the same, adapt to existing any a theftproof lock and use.Any existing lockmaking enterprise, does not need to increase input, does not need to increase equipment, do not need improving technique, does not need to train especially employee, can produce.This novel anti-theft lock pin, has unrivaled advantage from performance, in popularization, has good Social benefit and economic benefit prospect.

4, below in conjunction with accompanying drawing, the anti-theft lock of illegal insertion with regard to locking is described further.(see attached sheet)

Fig. 1: built-in lock pin pellet is arranged

(1) work pellet state: pellet two ends are wedged in lock core body and inner core, and lock core is in the lock state.

(2) anti-theft billiards state: position, pellet abutment is at inner core outer place up and down, latch-up-free effect at this moment.

Fig. 2: the state after this lock key inserts

(1) pellet that works becomes in good order, and position, upper and lower pellet abutment is at inner core outer place.

(2) anti-theft billiards lower end is inserted in the preset circular hole of key, and position does not change, and does not affect lockset and normally uses.

Anti-theft billiards is shifted, and in wedging lock core body, lock core locks.

5, embodiment

This illegal insertion is with regard to locking anti-theft lock core, particular requirement is not had to material, special provision is not had to appearance and size, except built-in pellet status flag and key local to some extent difference, other and existing anti-theft lock core are as good as, be adapted to any a known lock, existing ripe implementation method and technique.

Claims (1)

1. an anti-theft lock core for illegal insertion just locking, its technical characteristic is: built-in lock pin pellet comprises work pellet and anti-theft billiards, and in work pellet and existing known anti-theft lock core, pellet arranges state and is as good as; The state that arranges of anti-theft billiards is, it often organizes the position, abutment of upper and lower pellet, all at inner core outer place, its matched key is in the position of corresponding anti-theft billiards, for the circular hole of pellet termination can be held, before and after circular hole or periphery, be the gradient to round mouth place declivity towards pellet face, the gradient is identical with the gradient of key front end.
