Abstract

The utility model relates to an anti-stirred safety lock-core which is composed of a front core shaft and a rear core shaft. The front and the rear core shafts are provided with cylinders with different shapes. The anti-stirred safety lock-core is suitable for being matched with various locks, such as a door lock, a bicycle lock, a furniture lock, etc. The disadvantage that the exiting lock core has poor anti-stirred performance is overcome, and the purpose that a lock is prevented from being unlocked by a sickle-shaped hook that is a master key is achieved. The utility model has the advantages of simple structure, strong practicability, good use effect and low cost.

Description

Anti-stirred safety lock-core

The utility model is to belong to the matching used lock core of a kind of and existing lock.

Popular in the market various lock kind is a lot, its anti-poor performance of dialling, and the effect that does not reach burglary insurance, the theftproof lock that developed recently gets up, only on intensity that improves dead bolt, lock body and pick-proof performance thereof, have breakthrough, but in the whole system of lock, privacy degrees requires the highest, and the precise part that seems the weakest---lock core does not also have great improvement again.It is being subjected to one under the prerequisite of opening direction rotating torque, if the key of hook from mandrel with a falciform, slide fast from inside to outside, perhaps with pellet shot from a slingshot selectively one by one to one side pressure of the pellet shot from a slingshot hole of mandrel seat, perhaps in pin spoon groove, shake, it is that the line of demarcation separates with mandrel and mandrel seat contact surface that the capital makes first floor and second layer pellet shot from a slingshot, reaches the purpose (above-mentioned falciform hook and the part that applies moment just can be described as a kind of form of MASTERKRY) of unlatching.

Also have a kind of new-type theftproof lock, though key is adopted " it " font structure of special shape, increased the difficulty that common falciform hook enters key, to being suitable for the special hook of " it " shape key, then it loses preventing function equally; Also has a kind of novel lock, for anti-thin slice inserts from the slit of mandrel and core boss, then with pellet shot from a slingshot in pairs be the open method that the boundary separates with the thin slice, adopted second layer pellet shot from a slingshot to use the special-shaped pellet shot from a slingshot scheme of trough of belt instead, but this pellet shot from a slingshot does not possess preventing function for the above-mentioned MASTERKRY that is called yet, so existing these locks still do not have the effect of burglary insurance, the requirement of incompatibility people use.

The purpose of this utility model is to provide a kind of supporting anti-safe lock cylinder of dialling of various locks such as door lock, bicycle lock, furniture lock, padlock that is adapted to for overcoming above-mentioned shortcoming.

Technical solution of the present utility model is: it is made up of preceding mandrel and back mandrel two parts, and design has difform pellet shot from a slingshot on the forward and backward mandrel.This lock core has been owing to adopted forward and backward mandrel two parts to form, the restriction whether rotation of forward and backward mandrel is aligned by pellet shot from a slingshot all, and this lock core and the supporting use of existing lock, back mandrel rotates the control dead bolt or lock is fastened, and promptly preceding mandrel is independently.So its burglary insurance performance is quite strong, really reached the purpose that prevents that falciform hook (master key) from dialling.

Accompanying drawing has been described an embodiment of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.The anti-safe lock cylinder of dialling that is proposed, it is made up of preceding mandrel (1) and back mandrel (2) two parts, and forward and backward mandrel (1) (2) key is identical, and match to contain and connect, design is equipped with round end pellet shot from a slingshot (5) in the pellet shot from a slingshot hole of its preceding mandrel (1), design again on the round end pellet shot from a slingshot (5) and be equipped with tack pellet shot from a slingshot (3), same design is equipped with round end pellet shot from a slingshot (5) in the pellet shot from a slingshot hole of mandrel (2) thereafter, the round end pellet shot from a slingshot (5) of front is gone up design and is equipped with tack pellet shot from a slingshot (3), and distribution design is equipped with special-shaped pellet shot from a slingshot (4).

Special-shaped pellet shot from a slingshot described in the utility model (4) is for a tack pellet shot from a slingshot with the level, promptly is " Shang " shape.

The utility model has been owing to adopted above technical solution, thus it can with the existing supporting use of various locks, the utility model has been described with existing door lock core is supporting and an example as Fig. 4, need only and on preceding mandrel, design a vertical fixedly snap ring; An example after having described the utility model and existing padlock and join as Fig. 5, if on preceding mandrel longitudinal register pellet shot from a slingshot of design.

During the utility model assembling pellet shot from a slingshot (as Fig. 4 Fig. 5), after having adorned first floor round end pellet shot from a slingshot (with pellet shot from a slingshot hole energy sliding fit), when dress second layer pellet shot from a slingshot, adorn the tack pellet shot from a slingshot earlier, be used for controlling the position of mandrel, refill special-shaped pellet shot from a slingshot, and major part inwardly, the microcephaly adorns back-moving spring outwardly then, and envelope pellet shot from a slingshot hole gets final product.The quantity of its various pellets shot from a slingshot of packing into and position can be decided as requested.

Various locks such as the utility model and existing door lock, bicycle lock, padlock, furniture lock are supporting to be had only the key skewer gone in the key that forward and backward mandrel aligned and rotates, just can unblank, as Fig. 4, shown in Figure 5.Because tooth on the key and the effect that enters the first floor pellet shot from a slingshot in the forward and backward mandrel have only when key is got back to the starting position, key could be transferred to, and at this moment forward and backward mandrel playbacks simultaneously.If mandrel rotated an angle before idea made, then before mandrel naturally will back mandrel key sealing, mandrel after can't rotating again and unblanking.The mandrel pellet shot from a slingshot aligns if the key that skewer is gone into can make the back, and then under the condition that preceding mandrel pellet shot from a slingshot does not align, key equally also can't rotate and unblank.Therefore, forward and backward mandrel all has unique selection to key equally.If the way of dialling with the falciform hook (that is: MASTERKRY open way), externally applied forces square then before can only acting on the mandrel, and can't rotate mandrel afterwards, still can't push lock aside.

The utility model is the obvious advantage of tool compared with prior art, it has overcome the anti-shortcoming of dialling poor performance of existing lock pin, be applicable to various locks such as door lock, bicycle lock, furniture locks supporting, form various new anti-theft safety locks, really reached and prevent the falciform hook, be i.e. the purpose dialled of MASTERKRY, and simple in structure, cost is low, and is practical, and result of use is good.
