The specific embodiment

To shown in Figure 6, a kind of key sealed steel lock is made up of lock body 1, key, lock bridge 12 and lock core 16 as Fig. 1.Lock core and lock body fixedly fuse, and lock core is a stationary fixing, and end periphery is fixed with corresponding lock body under the lock core, the lock body hollow between the key port 14 of lock core keyhole and base lower end.This section lock body laterally is equipped with key sealed steel slice 5.The lock core outer end is arranged with lock tube 8, and lock tube is for rotating lock tube, is provided with one or two layers of pellet shot from a slingshot 24 according to traditional structure on lock tube and the lock core and structure is opened in the latch lock make and break, so be not repeated.Lock tube upper end is provided with the finger 9 of stirring the tongue pin, and finger is stirred tongue pin 10 and made in the locked groove 11 on its lock bridge that can feed and withdraw, makes lock bridge 12 opening and closing, finishes the keying of lock.The slewing area of finger is by alignment pin 13 controls.The lock tube side is provided with lock tube gear 7.A side axle is provided with power transmission shaft 3 in the lock body, and the one end was connected and is positioned at the outer unlatching handwheel 2 of base after power transmission shaft and base were coupling.The power transmission shaft of answering with the lock tube gear mesh is provided with broken teeth wheel 6, and the power transmission shaft of broken teeth wheel lower end is provided with cam 4.Axle is provided with key sealed steel slice on the lock body corresponding with cam.The key port of holding under the corresponding lock on the key sealed steel slice is provided with keyhole 15.Key is the syndeton of separating of key bit 19 and key body 20, and key bit separates with key body and is positioned at lock core keyhole when unblanking.

Be provided with spring 17 between one end of described key sealed steel slice and the lock body, the other end of key sealed steel slice contacts on the cam periphery.The effect of spring 17 is that key sealed steel slice is resetted.

Described key bit lower end is provided with grab groove 21, and key body is provided with movable grab 22 that is held in the grab groove and the grab button 23 of controlling this activity grab.The grab button slides on the chute on the key body and utilizes the groove on it that movable grab is inwardly shunk, and makes the key bit lower end break away from the key body front end, on the contrary affixed both.

The key port of described base 18 lower ends is provided with the lock core key hole separation distance is vertical.Described key sealed steel slice is on the key port and the lock body between the lock core keyhole of end under the lock.Keyhole on the described key sealed steel slice can be relative with key port that is positioned at the beneath end of lock and lock core keyhole, or interlace.

As shown in Figure 1, lock and be locking states.During unlatching, key body and key bit are connected as a single entity, key port and keyhole key sealed steel slice on of key bit by end under the lock inserted in the lock core keyhole, make pellet shot from a slingshot lose top kayser core and lock body according to traditional approach, make one or two layers of gap between the pellet shot from a slingshot parallel with the gap between lock core and the lock tube in the insertion lock core, at this moment, the key bit afterbody just in time is positioned at the lock core rear end, after upwards promoting the grab button and making key bit break away from key body, take from key body outside key port.Rotating the rotation of unlatching handwheel drive power transmission shaft rotates cam and broken teeth wheel on it simultaneously, the salient point of cam holds key sealed steel slice one end shrinks the spring of its other end, key sealed steel slice is traversing, keyhole on the key sealed steel slice interlaces with the key port and the lock core keyhole that are positioned at the beneath end of lock, close lock core keyhole, strengthen antitheft.Simultaneously power transmission shaft rotates the broken teeth wheel that makes on it and rotates simultaneously, and the gear on the broken teeth wheel contact meshing with lock tube gear 7, and drives lock tube and make the tongue pin break away from cotter way around the finger that lock core rotates and then drives on it simultaneously, locks unlatching.Otherwise motion, then lock cuts out, so be not repeated.

In a word, the utility model has fundamentally changed traditional structure, makes any robber person all can not damage this lock.Can extensively promote the use of.
