Referring to fig. 1 to 7, a mechanical lock including an outer handle 10 disposed outside a door, a lock cylinder 20 disposed inside the door and having one end connected with the outer handle 10, and an inner handle 30 disposed inside the door and connected with the other end of the lock cylinder 20, further includes:
A movable seat 40 movably disposed in the inner handle 30 and having one end abutting against the square core 21 on the lock cylinder 20;
The switch 50 is movably arranged on the inner handle 30 and is connected with the other end of the movable seat 40;
The clutch assembly 60 is arranged in the outer handle 10 and is connected with the square core 21, the push switch 50 can drive the square core 21 to move back to the outer handle 10, so that the clutch assembly 60 is locked with the outer handle 10, the square core 21 and the clutch assembly 60 can be driven to rotate to unlock the lock cylinder 20 by rotating the outer handle 10, or the square core 21 can be driven to move towards the outer handle 10, so that the clutch assembly 60 and the outer handle 10 are unlocked, and the outer handle 10 idles.
In the present invention, the "safety function" is realized by the switch 50, specifically, the default door lock is in the state of releasing the safety function, in this state, the switch 50 drives the movable seat 40, the square core 21 and the front core 64 to move back to the external handle 10, when the front core 64 moves, the clutch pin 68 on the clutch 61 is forced to move outwards and extend into the third clutch groove 67 on the external handle 10 partially, so as to connect the clutch assembly 60 with the external handle 10, so that the external handle 10 can be driven to rotate when rotating, and the lock core 20 is driven to unlock, in the state of opening the safety function, the switch 50 needs to be pushed to move towards the external handle 10, and when the front core 64 moves, the movable seat 40, the square core 21 and the front core 64 are sequentially pushed to move towards the external handle 10, the clutch pin 68 is dropped from the third clutch groove 67 to be fully accommodated in the first clutch groove 63 and the second clutch groove 66, so that the external handle 10 and the clutch assembly 60 are disconnected, and the external handle 10 is prevented from rotating, thereby the user can still feel the door lock is still in the state of opening the safety function.
The clutch assembly 60 includes:
The clutch 61 is provided with a through groove 62 penetrating along the moving direction of the square core 21, and the clutch 61 is provided with a plurality of first clutch grooves 63 which are communicated with the outside and the through groove 62 simultaneously along the circumferential direction of the clutch 61;
A front core 64 movably arranged in the through groove 62, one end of the front core is connected with the square core 21, the other end of the front core is connected with the outer handle 10 through a return spring 65, and a plurality of second clutch grooves 66 are arranged on the front core 64;
A plurality of third clutch grooves 67 provided on the inner sidewall of the outer handle 10;
the clutch pins 68 may be completely accommodated in the first clutch groove 63 and the second clutch groove 66, so that the outer handle 10 idles, or may be driven by the front core 64 to extend into the third clutch groove 67 at least partially, so that the outer handle 10 may drive the square core 21 and the clutch assembly 60 to rotate to unlock the lock core 20.
As the first embodiment of the clutch pin 68, the clutch pin 68 is provided as a ball, which can greatly reduce the resistance of the clutch pin 68 when it is extended and retracted, and as the second embodiment of the clutch pin 68, the clutch pin 68 may be a clutch post including a prism, a cylinder, etc., without limitation.
The first clutch groove 63, the second clutch groove 66, the third clutch groove 67 and the clutch pins 68 are all arranged 4 at equal intervals, and the arrangement can ensure that the clutch assembly 60 and the outer handle 10 have better connection firmness when the door lock is in the safety release function state, so that the unlocking reliability is improved.
The lock cylinder 20 or the inner handle 30 is provided with an abutment groove 70 inclined toward the lock cylinder 20, and one end of the movable seat 40 can abut against the abutment groove 70 when the pushing square core 21 moves toward the outer handle 10.
The abutting groove 70 is arranged as a V-shaped groove with the opening end facing the inner handle 30, the inner handle 30 can be rotated to drive the movable seat 40 to rotate together in a state that the safety function is started by arranging the abutting groove 70, and because one end of the movable seat 40 abuts against the abutting groove 70 in the state, the movable seat 40 converts rotary motion into linear motion in the inner handle 30 under the forcing of the abutting groove 70 when rotating, and then drives the switch 50 to reset, so that the safety function can be relieved, and further, the safety function can be relieved when the abutting groove 70 is arranged as the V-shaped groove, and the convenience in use is greatly improved.
Of course, the present application is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications and substitutions without departing from the spirit of the present application, and these equivalent modifications and substitutions are included in the scope of the present application as defined in the appended claims.
