Detailed Description
The locking mechanism of the door lock according to the present invention will be described in further detail with reference to fig. 1 to 5.
The utility model provides a back locking mechanism of lock, is including rotating the back locking knob 2 that sets up at inner panel 1 and fixing the seat 3 that rotates on hand, wherein outside inner panel 1 was arranged in to one end of back locking knob 2, another end was arranged in inner panel 1 and is connected with cam 4 for it is rotatory that back locking knob 2 can drive cam 4, it also arranges inner panel 1 in to rotate seat 3, rotates along with the handle together.
This anti-locking mechanism still includes locking lever 5 and anti-locking spring 6, for the convenience of installing locking lever 5 and anti-locking spring 6, sets up anti-locking seat 7 between rotating seat 3 and anti-locking knob 2, anti-locking spring 6 installs on anti-locking seat 7, wherein state anti-locking seat 7 including anti-locking base 71 and apron 72, mounting groove has seted up down to anti-locking base 71, mounting groove has been seted up to apron 72, mounting groove cooperatees with last mounting groove down and forms the installation cavity that is used for installing anti-locking spring 6.
The locking rod 5 is also arranged in the mounting cavity, wherein the left end part of the locking rod 5 extends out of the mounting cavity to be abutted against the cam 4, and the right end part of the locking rod 5 passes through the back locking spring 6 and also extends out of the mounting cavity to be arranged opposite to the locking groove 31 of the rotating seat 3; an annular flange 51 is provided between the left and right ends of the locking lever 5, and one end of the back-locking spring 6 abuts against the annular flange 51 and the other end abuts against the side wall of the mounting cavity.
When the reverse locking knob 2 is rotated, the abutting point of the cam 4 and the lock rod 5 is moved from the low point position of the cam 4 to the high point position of the cam 4, so that the cam 4 can push the lock rod 5 to move towards the rotating seat 3, the right end part of the lock rod 5 is inserted into the lock groove 31 of the rotating seat 3, the handle cannot be rotated to unlock, and the reverse locking of the door lock is realized, and the traditional door lock does not need to additionally arrange a reverse locking bolt to perform reverse locking, so that the structure is simpler, the structure of the door lock is simplified, the manufacturing cost is reduced, when the reverse locking needs to be released, only the reverse locking knob 2 needs to be rotated reversely, the abutting point of the cam 4 and the lock rod 5 is moved from the high point position of the cam 4 to the low point position of the cam 4, so that the right end part of the lock rod 5 is pushed to be pulled out of the lock groove 31 of the rotating seat 3 under the elastic force of the reverse locking spring 6, and the locking of the lock rod 5 to release the locking of the rotating seat 3, thereby releasing the back lock.
