Description

A kind of lock core of anti-technology unlocking

Technical field

This utility model relates to a kind of lockset, the lock core of a kind of anti-technology unlocking.

Background technology

The history of lockset is long-range long, is the daily living article of people's door, along with the development of society, lock Tool the most increasingly modernizes, theftproof lock extensively being applied by people the most progressively, is seen everywhere in daily life, And people can use corresponding lock to preserve article or protection property safety.

The most common lock, has a common weakness, when specialty unlocking staff or illegal point After son has grasped unlocking technique, can open easily, so-called unlocking technique is exactly when opening at abnormal condition During lock, unlocking staff first passes through unlocking tool and lock core rotating shaft is somewhat rotated, and makes interior marble hole and outer marble hole Slightly offset from, after outer pellet is ejected lock core rotating shaft by interior pellet by unlocking tool, outer pellet can be deviateed Lock core rotating axis locking, it is impossible to dropping back in lock core rotating shaft, then outer pellet is ejected lock core by unlocking staff one by one Rotating shaft, thus reach the purpose of technology unlocking, so to seem, common theftproof lock is locked grasping skill of unblanking The personnel of art, as illusory, easily cause the property loss of people, and high-end theftproof lock mostly exist structure Complicated, cost of manufacture high, the most do not popularize.

Utility model content

The purpose of this utility model is for overcoming prior art deficiency to provide the lock core of a kind of anti-technology unlocking, adopting Be used in the interior marble hole outside lock core rotating shaft and length length be set, the structure of interior pellet that diameter is big, make lock core Interior pellet outside rotating shaft and interior marble hole gap shrinks, when technology unlocking, unlocking tool is by lock core rotating shaft After rotation, owing to the interior pellet outside axle center is little with interior marble hole gap, this interior pellet cannot be headed into outer bullet In sub-aperture, cause unlocking tool can be stopped by this interior pellet, it is impossible to enter keyhole and operate other pellets Enter unlocking condition position, reach the purpose cannot opened by tapered end by unlocking tool, can effectively prevent Technology unlocking, protects people's property safety.

The technical scheme that this utility model is used:

The lock core of a kind of anti-technology unlocking, including shell, is provided with several outer marble hole, outer pellet in the enclosure Being provided with outer pellet in hole, outer pellet is connected with outer marble hole top by back-moving spring, resets after extracting key Interior pellet can be resetted and withstand interior pellet by spring, is pinned by tapered end；Lock core rotating shaft it is provided with outside below marble hole, Arranging keyhole in lock core rotating shaft, position corresponding with outer marble hole in lock core rotating shaft is provided with interior pellet Hole, is provided with in interior pellet, and the interior marble hole outside lock core rotating shaft at least provided with one in interior marble hole Imperial palace pellet, diameter and the length of described imperial palace pellet are bigger than pellet in other inside axle center, long, reduce Imperial palace pellet and the gap of interior marble hole, can stop unlocking tool to carry out the interior pellet surveyed after this pellet Technology unlocking.When unblanking, key is by interior pellet jack-up in interior marble hole, by interior pellet outer pellet top Go out lock core rotating shaft, such that it is able to by key rotation lock core rotating shaft, reach the purpose unblanked, when extracting key Time back-moving spring outer pellet is resetted, fall in interior marble hole, stuck lock core rotating shaft so that it is cannot rotate, Tapered end is pinned.

The little outer marble hole that corresponding interior pellet is little is compared, at least provided with a diameter, in the outside of described enclosure, After lock core rotating shaft is rotated by unlocking tool, interior pellet can be made when technology unlocking cannot to be headed into outer marble hole, Cause the purpose being unable to reach technology unlocking.

This utility model simple in construction, cost of manufacture are low, use and set in the interior marble hole outside lock core rotating shaft Put length length, the structure of interior pellet that diameter is big, make the interior pellet outside lock core rotating shaft and interior marble hole gap Reduce, when technology unlocking, unlocking tool by lock core rotating shaft rotate after, due to the interior pellet outside axle center with Interior marble hole gap is little, owing to this interior pellet cannot be headed in outer marble hole, causes unlocking tool to be subject to The obstruction of this interior pellet, it is impossible to operating other pellets and enter unlocking condition position, reaching cannot be by work of unblanking The purpose that tapered end is opened by tool, can effectively prevent technology unlocking, protects people's property safety, have safely, The features such as good anti-theft effect.

Accompanying drawing explanation

Fig. 1 is that longitudinal the cuing open of this utility model attempts.

In figure: 1, shell, 2, outer marble hole, 3, outer pellet, 4, back-moving spring, 5, little outer marble hole, 6, imperial palace pellet, 7, keyhole, 8, interior marble hole, 9, interior pellet, 10, lock core rotating shaft.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, but not as this practicality Novel restriction.

In the construction shown in fig. 1, the lock core of anti-technology unlocking provided by the utility model, including shell 1, Several outer marble hole 2 it is provided with in shell 1, and in the outside within shell 1 at least provided with a diameter comparison The little outer marble hole 5 that the interior pellet 9 answered is little；Being provided with outer pellet 3 outside in marble hole 2, outer pellet 3 passes through Back-moving spring 4 is connected with outer marble hole 2 top；It is provided with lock core rotating shaft 10 outside, at lock below marble hole 2 Keyhole 7 is set in core rotating shaft 10, in position corresponding with outer marble hole 2 in lock core rotating shaft 10 is provided with Marble hole 8, is provided with interior pellet 9, and the interior marble hole 8 outside lock core rotating shaft 10 in interior marble hole 8 Interior at least provided with an imperial palace pellet 6, the diameter of described imperial palace pellet 6 and length ratio are in other inside axle center Pellet 9 is big, long.

When unblanking, key, by interior pellet jack-up in interior marble hole, ejects lock core by interior pellet outer pellet Rotating shaft, such that it is able to by key rotation lock core rotating shaft, reach the purpose unblanked, resets when extracting key Outer pellet is resetted by spring, falls in interior marble hole, stuck lock core rotating shaft so that it is cannot rotate, by tapered end Pin.

The above is only preferred implementation of the present utility model, it is noted that for the art For those of ordinary skill, on the premise of without departing from this utility model know-why, it is also possible to make some Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
