Abstract
The invention discloses a lock head adopting a blade structure, which comprises a lock shell, a lock cylinder and a plurality of blades, wherein the lock cylinder is mounted in the lock shell; a plurality of blade slots are formed in the lock cylinder; the number of the blade slots is the same as that of the blades; only one blade is inserted in each blade slot; and a blade spring is arranged between the part of the blade, which is exposed out of the lock core, and the surface of the lock cylinder. As each blade slot is placed with only one blade, the lock head has the advantages that the phenomenon that a lockset is damaged due to abrasion among the blades after long term use; the locking and the unlocking are smooth; the possibility of being unlocked by another key is very low; and the security is very high.
Description
Technical field
The present invention relates to field of lockset, relate in particular to a kind of blade construction tapered end.
Background technology
Present existing blade lock core structure is normally placed two blade shell fragments in each blade groove, disclosed a kind of shell fragment anti-theft lock end in the patent like publication number CN1405425A with multiple opening and closing structure, and it comprises the plurality of rows shell fragment; Every row has two shell fragments, and the same locking card key of staggered insertion has keyway on the shell fragment; Pressure or extrapolation original paper resetted it in shell fragment was provided with, and when unblanking, shell fragment moves; Locking card key inserts in the keyway, lock core is reversed be able to unblank.This type lockset can cause friction each other between two blades during key in plug, can cause leaf spring not go back to the position for a long time, and blade wear is serious, and the key plug situation that has some setbacks or the like occurs, and influences the application life and the quality of lockset.
Summary of the invention
The present invention aims to provide a kind of blade construction tapered end, can avoid interlobate friction, the wearing and tearing that prevent so produce.
For this reason; Technical scheme of the present invention is such: a kind of blade construction tapered end, comprise lock shell, lock core and some blades, and lock core is installed in the lock shell; Described lock core is provided with some blade grooves; The quantity of blade groove equates with the quantity of blade, is inserted with in each blade groove and only has a blade, blade to expose between part and the plug face of lock core to be provided with leaf spring.
As the further technical scheme of the present invention: the direction of each blade groove is parallel to each other, between adjacent two blade grooves for mutually from relation; Also be provided with a locking side column groove in the lock core; The direction of locking side column groove is perpendicular to the direction of blade groove; Be inserted with the locking side column of " protruding " shape in the locking side column groove; Part corresponding with locking side column both sides recess on the locking side column groove respectively is equipped with a mounting, is provided with stage clip between locking side column both sides recess and mounting; Described lock shell is provided with lock slots in the position corresponding with the locking side column groove and cooperates with described locking side column; Described blade is provided with groove in a side corresponding with locking side column, and groove cooperates with the locking side column bottom.
For leaving relation mutually, be meant between adjacent two blade grooves not contact, do not interfere between described adjacent two blade grooves.
As the further technical scheme of the present invention: also be provided with key on the lock core, the direction of key is all vertical with the direction of the direction of blade groove, locking side column groove; Described blade is provided with convexity, and this convexity cooperates with the key that inserts key.
In key, do not insert under the state of key; Each blade is in initial position, and this moment, the groove on the blade left with locking side column mutually, thus locking side column by blade in the locking side column groove to outer release; Thereby part stretches out in outside the lock core and inserts in the lock slots of lock shell; Make lock core and lock shell facies to fixing, reach the purpose of locking, the stage clip between locking side column and mounting is in compressive state at this moment.
Behind the key that insertion is complementary; Each blade makes that because of the convexity on it receives the control campaign of key the groove on each blade is all aimed at locking side column, and the promotion of the stage clip of locking side column this moment between itself and mounting is moved down; Take in the lock core fully; The groove of each blade is inserted in the bottom, thereby lock core and lock shell relative fixed no longer, and key can drive lock core rotation completion and unblank.This state lower blade spring all is in compressive state.If the key that inserts is not the key that is complementary with this lock core, then can't make the groove of each blade all aim at locking side column, can't make in the locking side column income lock core, can't accomplish and unblank, thereby reach the purpose of antitheft.
When extracting key, each blade returns initial position under the elastic force of leaf spring separately, and locking side column is pushed in the lock slots of lock shell again, gets into locking states again.
Have only an independent blade in the tapered end provided by the invention in each blade groove, stopped the phenomenon that wearing and tearing between long-term use rear blade damage lockset, and the present invention to open and close lock smooth and easy, mutual opening rate is extremely low, confidentiality is high.

Fig. 8 is a blade sketch map of the present invention.
The specific embodiment
Referring to accompanying drawing; Lock core 1 is installed in the lock shell 2, has locking side column groove 3 on the lock core 1, eight blade grooves 4,5, eight blade grooves of key were listed in lock core 1 both sides in 4 minutes; And staggered display; The direction of each blade groove 4 is parallel to each other, and the direction of locking side column groove 3 is vertical with the direction of blade groove 4, and the direction of the direction of key 5 and locking side column groove 3 and the direction of blade groove 4 are all vertical.Also have lock slots 6 on the lock shell 2, cooperate with locking side column groove 3 on the lock core.Be provided with the locking side column 7 of " protruding " shape in the locking side column groove 3, and the correspondence position of depression respectively is equipped with a mounting 8 in locking side column 7 both sides on the lock core 1,7 of mounting 8 and locking side column also have stage clip 9.Be provided with a blade 10 in each blade groove 4; One side of blade 10 has the groove of " V " shape; The position relative with groove has convexity; When each blade 10 was in the blade groove 4 separately, groove was all towards locking side column 7, and each blade 10 stretches out between the external surface of outer part of blade groove 4 and lock core 1 all has leaf spring 11.
Like Fig. 3; When lockset is in locking states; Groove on the blade 10 leaves locking side column 7, and locking side column 7 extends upwardly under the effect of blade 10 from outside the lock core 1 and get into lock slots 6, makes lock core 1 and lock shell 2 relative fixed; Reach the purpose of locking, this moment, the stage clip 9 of 8 of locking side column 7 and mountings was in compressive state.
Like Fig. 4; When inserting key unlocking, each blade 10 is taken in lock core 1 because of making convexity on it and cooperating of key blade 10, all aims at locking side column 7 until the groove of each blade 10; This moment, locking side column 7 was inserted the groove of each blade 10 at the effect lower bottom part of stage clip 9; Thereby in the income lock core 1, make lock core 1 and lock no longer relative fixed of shell 2, key can make lock core 1 rotation completion unblank then.Each leaf spring 11 all is in compressive state under this state.
After extracting key, the elastic force of leaf spring 11 makes each blade 10 playback, thereby makes locking side column 7 insert the lock slots 6 on the lock shell 2 again.
