Description

The tapered end of lock core idle running

Technical field

The utility model relates to a kind of lockset, promptly a kind of tapered end of lock core idle running.

Background technology

The patent No. is that ZL200420014479.6's " idle running type blade locking head " (hereinafter to be referred as " patent one ") and " a kind of opening and prizing prevention lock " (hereinafter to be referred as " patent two ") of ZL200520054908.7 and the common advantage of three utility model patents of ZL200620097142.5 " a kind of lamina idle-run tapered end " (hereinafter to be referred as " patent three ") are that lock core can dally, this has played certain effect of controlling to turning on lock by force, also increased simultaneously the difficulty of technology unlocking, its theftproof performance has had further raising.But three's common drawback one is must add a turning set and rotation strip between lock core and the lock housing (the component title of said function is inconsistent in three patents, unified in this manual name back to they Old Name not with draw notes), this can increase the cost of manufacture and the material cost of product undoubtedly; The 2nd, the idle running rate is not high.In the manual of " patent two ", mention " to be encoded to 123456 and to be encoded to two keys of 223456 be example; the former be and locks supporting key; the latter is a non-matching key ... " these two keys except that first tartar slightly the difference, all the other are identical, therefore, the keyhole rear lock core of the tapered end that second key insertion first key matches can not dally, and the positive and negative both direction twisting key lock of exerting oneself a little can be opened in the same old way.Above-mentioned two similar keys are a special case, and actual idle running rate is more much smaller than this special case.From the Figure of description of above-mentioned three patents as can be seen, lock core will be realized idle running, its prerequisite is that the clutch bar must effectively be shouldered on the rotation interface that makes its lateral surface be in lock core and turning set by two blades or two pellets shot from a slingshot, behind the key that does not match or other objects insertion keyhole, the probability that can satisfy this condition is not high, if the different key billet of effective height (referring to do the face of tartar) is inserted keyhole examination rotary locking cylinder respectively with Materials with High Strength processing is several, always having one can make lock core not dally, therefore, can stay the chance of turning on lock by force.Rotation strip in second embodiment of " patent three " (former title on-of pin, only this draws notes) is zigzag ruler shape, and this trisquare there is no practical function in this embodiment.In the 3rd embodiment of " patent two " and " patent three " with one in pearl substitute rotation strip, its idle running probability is higher relatively, but also not much else.

The utility model content

In order to solve in above-mentioned three patents common two technical problems that exist, the utility model provides a kind of simple structure, blade locking head and ball lock head that the idle running rate is high.

The utility model is achieved in that a rotor and latch hook are set substitutes turning set and rotation strip or middle pearl in above-mentioned three patents.Concrete grammar is that set latch hook is

Shape, its both sides, long limit are arc surface or slope; Lock core hole inwall on the lock housing is provided with the latch hook pod, and the clutch bar groove inner end of lock core or the notch of clutch bar groove are provided with the latch hook holding tank outward, and the rotor big end surface is provided with the latch hook translot, and the little end surface of rotor is provided with or is equipped with the open and close lock and dials tongue; Under the normality crouch on lock housing in the latch hook pod in the long limit of latch hook, and the minor face of latch hook then inserts in the latch hook translot of rotor, and rotor can not rotate with regard to being lockable like this; After matched key inserts keyhole, the whole centerings of V-arrangement circumferential groove of the breach of blade or pellet shot from a slingshot, when lock core rotates to clutch bar groove or latch hook holding tank aligning latch hook, the long limit of clutch bar and latch hook is pushed by spring and makes the long limit of latch hook break away from the latch hook pod on the lock housing and enter in clutch bar groove or the latch hook holding tank, just in time be in outside the long limit of latch hook at this moment on the rotation interface between lock core and the lock core hole, continue rotary locking cylinder, thereby latch hook will rotate and then and drives the rotor rotation and reach and unblank or the purpose of locking.When not matching key or other objects insertion keyhole, most latch hook long legs that can occur divide the latch hook pod that breaks away from lock housing and clutch bar groove or the latch hook holding tank that enters lock core under the effect of spring, because of the both sides on the long limit of latch hook are designed to arc surface or slope, so the notch edges of clutch bar groove or latch hook holding tank can be easy to do grows that the limit is forced back in the latch hook pod and the idle running that do not influence lock core with latch hook during rotary locking cylinder.The utility model substitutes the big parts of turning set and the rotation strip or the middle pearl widget of " patent one ", " patent two ", " patent three " with simply constructed rotor and these two widgets of latch hook, labor and material saving not only, but also improved the idle running rate of lock core greatly, as seen this technological transformation is very remarkable to reducing product cost and improving the theftproof performance effect of product.
