For solving the problems of the technologies described above; The technical scheme of the utility model is: new door lock; Comprise lock body that is installed on the swing leaf and the lockhole that is installed on seldom moving door leaf or the doorframe; Be rotatablely equipped with first lock core in the said lock body, be provided with first spring marble between the said lock body and first lock core, said first lock core is provided with first keyhole that runs through said first lock core; Be provided with first key that is used to open said first spring marble in said first keyhole, be installed with first gear on said first lock core; Dead bolt; Said dead bolt is slidingly mounted on the said swing leaf; Said dead bolt is provided with first tooth bar that is meshed with said first gear, and said dead bolt is provided with a sliding chamber, is slidingly fitted with second lock core in the said sliding chamber; Be provided with second spring marble between said second lock core and the dead bolt, said second lock core is provided with second keyhole; A side relative with said first tooth bar on the said dead bolt is provided with second tooth bar; With second gear that said second tooth bar is meshed, the both sides of said second gear are installed with driver part respectively; Fixed installation is useful on second key of opening said second spring marble in the said lockhole; Said second lock core is provided with stopping element, and the said stopping element and second gear offset.

As a kind of improvement, said first is provided with jog on the key, and said jog is corresponding with the first spring marble position.

As a kind of improvement, said driver part comprises rotating and is installed on the swing leaf and is positioned at the inboard inner handle of said swing leaf and rotates the outdoor handle that is installed on the swing leaf and is positioned at the said swing leaf outside.

As a kind of improvement, said stopping element comprises the baffle plate that is fixedly installed on said second lock core.

As further improvement; Said first key comprises unblank halfbody and the handle halfbody that links together through bearing pin; Said jog is arranged on the said halfbody of unblanking; Said unblanking is provided with disc spring between halfbody and the handle halfbody, and said disc spring one end is fixedly installed on the said bearing pin, and the other end is fixedly installed on the said handle halfbody.

As further improvement, the said halfbody of unblanking is plugged in said first keyhole and stretches out said first lock core.

Owing to adopted technique scheme, the beneficial effect of the utility model is: because first lock core, second lock core and stopping element have been installed on swing leaf, seldom designing lockhole on moving door leaf or the doorframe; In lockhole, be provided with second key, make to have only with first key and open first lock core, dead bolt can slide; Have only second key to open second lock core, second lock core and dead bolt can slide relatively, and stopping element can not braked by second gear when door lock is sealed; Otherwise stopping element will be braked by second gear; Thereby cause dead bolt to be braked, first lock core can not turn round and put in place, and then the operator can't take out key; Thereby having realized only locks a door puts in place and can take out first key, has improved the theftproof performance of unit security door.

Be installed on the swing leaf and be positioned at the inboard inner handle of swing leaf and rotate the outdoor handle that is installed on the swing leaf and is positioned at the swing leaf outside because driver part comprises rotating, convenient when making this door lock operation, first key just plays the effect of opening first spring marble; The application of force not when unblanking, but rely on the inner handle or the outdoor handle application of force, when rotating inner handle or outdoor handle; Driving second gear rotates; Slide thereby drive dead bolt, both convenient, laborsaving again.

Because first key comprises unblank halfbody and the handle halfbody that links together through bearing pin, makes the Key structure of winning simple, realized inserting in a side of door, can extract out from the opposite side of door, the operator is easy to use.
