Summary of the invention

In view of such problem, the present invention proposes a kind of scheme, and the anti-tongue that promptly can guarantee lock body can the sharp impacts buckle and make a noise, and can guarantee that again said anti-tongue can be pushed back in the lock body reliably.

Lock is used buckle, and the dead bolt hole that it is provided with the buckle locating hole and supplies dead bolt to pass is characterized in that, and is jagged with the lateral location of buckle at said lock.

Further technical scheme can also be on the horizontal edge of said breach, bending edges to be set.

Further technical scheme can also be, also comprises being arranged on said lock with the inboard end box of buckle, and box of the said end is provided with adaptive end box locating hole and the lock tongue cavity of dead bolt hole that passes with buckle locating hole that is provided with on the buckle and confession dead bolt with said lock; Box of the said end is provided with the extension block to the side protrusion, and said extension block is positioned at the inboard of said lock with the breach of buckle.

Further technical scheme can also be that the both sides of said extension block also are provided with the side convexity.

According to technique scheme; When at closing time; The certain displacement of the preliminary jack-up of extension block of the said end box of the anti-tongue of lock body below the gap position of said buckle at first is positioned at said breach; When it moves to the middle part of said buckle, further be pushed in the lock body again by the middle part of said buckle, thereby avoided said anti-tongue directly to settle at one go and the difficulty door appears, defective that the noise of closing the door is big.

Because the present invention has These characteristics and advantage, can be applied to the lockset product and particularly have in the lockset product of anti-plugging function.
