Abstract

The utility model relates to an anti-prizing door lock. The utility model is characterized in that a lock tongue rotating mechanism which is composed of a lock tongue turntable, a lock core turntable and a riveting sheet is arranged in a lock body corresponding to a lock core. Because the lock tongue can be rotated for 90 DEG after a door is locked, the lock tongue is hung on a door catch to achieve the purpose of prizing prevention. The utility model has the advantages of simple structure, good anti-prizing performance and good safety performance.

Description

Anti-prizing door lock with rotary tonge

The utility model relates to a kind of pick-proof door lock.

General door lock all is provided with locks mechanism, but less certain mostly, door can be opened as long as force dead bolt to withdraw from the instrument of opener and so on insertion crack between a door and its frame.

The purpose of this utility model is to provide a kind of pick-proof door lock of rotating lock tongue.

The technical solution of the utility model is: an energy is set on lock body dead bolt is rotated 90 ° dead bolt rotating mechanism, tangle knocker after making the rotating mechanism action that dead bolt is rotated by lock core chip, reach the purpose of pick-proof.

The utility model is simple in structure, and the anti-prying performance is good.

Fig. 1 is the utility model sectional view;

Fig. 2 is Fig. 1 vertical view;

Fig. 3 is Figure 1A-A direction view;

Fig. 4 is the dead bolt state diagram of locking a door after rotating.

Below in conjunction with the description of drawings most preferred embodiment:

The utility model is locked in existing common door and is provided with the dead bolt rotating mechanism.Former lock mainly is made of dead bolt 1, lock body 2 and lock core, the dead bolt rotating mechanism is made up of dead bolt rotating disk 3, lock core rotating disk 4 and riveting sheet 5, lock core rotating disk 4 is arranged in the lock body corresponding with lock core by riveting sheet 5, there is an oblong aperture corresponding with lock core chip at riveting sheet center, the riveting sheet is followed rotation during rotational lock core, and drives lock core dial rotation (block that blocks the riveting sheet is arranged on the rotating disk) by the riveting sheet.There is a perpendicular shifting block 6 on one side of lock core rotating disk, and another side has the horizontal shifting block 7 of one 7 font.The dead bolt rotating disk is fixed on the dead bolt pull bar, one side the dead bolt rotating disk have an open slot 8, corresponding with the horizontal shifting block of 7 fonts of lock core rotating disk 7, the edge of dead bolt rotating disk is provided with the block 9 of protrusion, is vertically installed with block 10 on the dead bolt rotating disk.

When locking, rotational lock core, lock core chip drive the riveting sheet and force the lock core dial rotation, and the horizontal shifting block 7 on the lock core rotating disk forces dead bolt rotating disk 3 to rotate by open slot 8, thereby make dead bolt rotate 90 ° and tangle knocker.

When opening the door, after rotational lock core, the horizontal shifting block 7 on the lock core rotating disk forced the dead bolt counter-rotating by open slot 8, block/10 on the perpendicular shifting block 6 compressing dead bolt rotating disks on the lock core rotating disk overcame spring force and open the door.

Claims (4)

1, a kind of pick-proof door lock of dead bolt rotation, have dead bolt (1), lock body (2) and lock core, it is characterized in that also having the dead bolt rotating mechanism that constitutes by dead bolt rotating disk (3), lock core rotating disk (4), riveting sheet (5), described dead bolt rotating disk (3) is fixed on the dead bolt pull bar, and lock core rotating disk (4) is arranged in the lock body corresponding with lock core by riveting sheet (5).

2, pick-proof door lock according to claim 1 is characterized in that there is an oblong aperture corresponding with lock core chip at the center of riveting sheet (5).

3, pick-proof door lock according to claim 1 is characterized in that having on the lock core rotating disk perpendicular shifting block (6) and horizontal shifting block (7).

4, pick-proof door lock according to claim 1 is characterized in that open slot (8) is arranged on the dead bolt rotating disk (3).The edge of dead bolt rotating disk is provided with and protrudes block (9), is vertically installed with block (10) on the dead bolt rotating disk.
