New description: [New technical field] This creation provides a clutch mechanism for door locks, especially a clutch mechanism that can make the outer handle idling in the locked state. [Prior Art] The latch of a general door lock is controlled by a handle, and is movable between a closed door position that protrudes from the edge of the door panel and a door open position in the reduced entry plate. A knob is usually mounted on the inside of the door to lock so that the outer handle cannot be rotated to manipulate the latch to retract to the open position. However, in the locked state, if the unlocked unclear user frequently presses the outer handle frequently, especially when the operating force of the outer pressing handle is too large, the internal components of the door lock are often damaged. The life of the door lock is reduced. In the new case of certificate number M264344 "Door lock with cooperation", the creator designed a structure that can make the outer handle form a two-turn operation in the locked state, thereby improving the internal member of the door lock which is easily affected by the outer handle. The problem of damage caused by the transmission of torque. However, the structure of the new case is not convenient in assembly. Therefore, the creator further designs a clutch mechanism that can be adapted to a general door lock installation, which can transmit the torque of the outer handle in a normal state to manipulate the latch of the door lock to retract, and can also be in a locked state. The torque transmission of the outer handle is cut off, so that an idle rotation is formed when the outer handle is operated. M293304 [New content] The main purpose of this creation is to provide a kind of (four) (four) clutch mechanism, Nahe machine shot to make the transfer handle torque "when the money and (four) (four) pieces are separated, (four) broken lock outside the (four) twist, 'hunting to avoid The improper force applied to the inner I5 member of the door lock via the outer handle is particularly simple in structure and convenient in assembly. The clutch mechanism according to the present invention comprises: a lock case, the lock case The inner assembly m pulls back at least one traction member of the lock and is movable to lock the (four)-locking block, the traction member has a perforation in the center; the outer mandrel 'the outer wire shaft is outside the door lock The inner portion of the handle is internally provided with a spring for pushing the front end of the mandrel into the tooth hole of the traction member, and an extension portion is provided at the front end of the outer mandrel, the extension portion having and perforating The inner wall has a contactless reduced outer diameter; and the push cup is disposed on the inner side of the locking block and has a beveled surface at one end, the bevel may be transversely connected with the front end extension of the outer mandrel; when the locking block is oriented External displacement makes lang formation not _ In the state, the outer mandrel forms a engagable engagement with the traction member; when the locking block of the door lock is displaced inwardly to form a lock, the push rod is displaced in the direction of the bolt and the outer core is axially outward. Pushing (4) the position where the front end is separated from the inner wall of the perforation to release the connection relationship between the outer mandrel and the traction member, and the torque transmitter of the outer handle of the door lock can be cut off. M293304 is better for the purpose of other purposes: The advantages and features will be clarified by the following detailed descriptions of the & columns and with reference to the drawings. [Embodiment] Various creations can be used for the creation of the S.

The front end 63 1 of the mandrel 63 can be inserted into the central perforation 8 21 of the corresponding traction member 8 2 for transmitting the torque of the outer handle 61 to be manipulated to manipulate the lock 7 2 to be retracted; And a spring 54 on the rear side of the mandrel 53 is provided inside the base portion 52 of the inner handle assembly 5 for providing the biasing potential of the mandrel 5 3 outwardly, so that the mandrel 53 The front end 5 3 i can be threaded into the corresponding traction member 8 1 . The central perforation 8 1 transmits the torque of the inner handle 5 1 to be manipulated to manipulate the latch 7 2 to retract. The present invention is characterized in that the core pumping 6 3 can be separated from the coupled traction member 82 in the locked state, and the separation or engagement of the spindle 63 and the traction member 8 2 can be matched with the second figure, As shown in the third figure, the present invention is provided with a push rod 4 at the inner end surface 74 of the blocking block 77. In the present embodiment, the push rod 4 is detachable and disposed on the (four) plane 7 along the lock n-direction. 7 Q, but the push rod 4 can also extend into the inner end surface 770; the push rod 4 has a rear end 4ι and a front end 4 2 'the rear end 4 1 is coupled to the (four) surface 7 7 One of the M293304 recesses 775 is provided, and the front end 42 extends through the notch 8 7 1 of the spacer ring 7 into between the two traction members 8 1 and 8 2; and the front end 42 has a slope 4 1 1, In the present embodiment, the front end 42 is formed in a head shape and has an opposite slope 4 21 on each side. This creation is provided at the front end 63 1 of the outer mandrel 63, an extension portion 63 2 extending in the axial direction, the extension portion 63 2 having a reduced outer diameter that is not in contact with the inner wall of the perforation 8 ^ 1 , In this embodiment, the extension #6 3 2 has a tapered shape with a beveled surface of the trailing edge 63 3 , and when the outer mandrel 63 is pushed into the perforation 8 2 1 of the traction member 82 by the elastic force of the spring 64, The front end inclined surface 63 3 of the extending portion 6 3 2 is blocked by the front end inclined surface 421 of the push rod 4 to form a positioning. .

The pushing of the end face 7 7 :: 4 will advance in the extending direction of the latch 72. At this time, since the push rod 4 and the front end extension 6 3 2 of the outer mandrel 63 are obliquely intersected: Chess, so that the displacement of the push rod 4 in the direction of the bolt will drive the shaft 6 3 to move in the direction of the vertical bolt, and the outer shaft 63 will be pushed outward to the front end thereof. 2 1 position of the inner wall to release the connection relationship between the outer mandrel 63 and the outer member 82. M293304 Referring to the sixth and seventh figures, when the front end 6 3 1 of the outer mandrel 63 is separated from the outer (four) piece 8 2, the external mandrel 6 3 is required to transmit the external handle 6 1 torsion. The cutting is performed, so that the pressing of the outer handle 6 1 forms a rotation mode that does not drive the lock 72 displacement, that is, after the locking block 7 7 of the door lock is displaced to the inner side to form a lock, the user's operation on the outer handle will be formed. It is idling to prevent improper force from being transmitted to the internal components of the door lock via the outer handle. The structure of the present invention is quite simplified, and the assembly is also quite convenient, and f is inclined by the inclined surface 421 at the front end of the push rod 4 to make the extension of the front end of the outer handle 3 such that the outer handle 63 is equivalent in performing the clutch movement.
