Abstract

The utility model discloses a clutch structure of a lock. The structure comprises a drive pipe, at least one hole arranged on an inner pipe wall; a key-driving pipe which is arranged inside the drive pipe with at least one hole arranged on the pipe wall; a horizontal element is arranged in the hole of the key-driving pipe, which can be selected to or not to be joggled with the hole of the drive pipe; an axial gliding element which is inserted into the key-driving pipe and provided with a non-axial setting groove; and a rotating element which is inserted into the axial gliding element and provided with a pin which extends into the non-axial setting groove of the axial gliding element. By rotating movement of the rotating element, the pin of the rotating element and the non-axial setting groove of the axial gliding element jointly move to cause axial displacement of the axial gliding element in order to control the movement of the horizontal element arranged in the key-driving pipe; an external drive pipe is separated from the key-driving pipe when the lock body is locked up at the first position; and the external drive pipe is connected with an external knob to realize the racing of the knob at a certain preset angle when the door lock is locked up, resulting in that the knob is not easy to be damaged.

Description

The clutch structure of lock

Technical field

The utility model relates to a kind of lock, refers to a kind of clutch structure of lock especially.

Background technology

The structure of generally commonly using the horn lock as shown in Figure 1, in having haply, outer handle A, B, in being connected to, outer driving tube C, the end of D, housing group E inside is equiped with leads the F of mechanism that contracts, can be by interior, outer driving tube C, the other end C ' of D, D ' drives, be installed in lock bolt on the door with operation, the inside of outer driving tube D has can be with key operated lock group, when key inserts in the lock group, operation is installed in the key driving tube of outer driving tube D inside, and described key driving tube has the wing of driving G, when it rotates, can drive and lead the F of mechanism that contracts, be installed in lock bolt on the door with action.

Horn lock's structure of commonly using is to come operable lock group interlock chain driving tube to drive the described F of mechanism that contracts that leads with key to make the plunger latch head of lock bolt remove receipts.Because during the lock body locking, the handle that the lock group is installed is limited by the inner combination of lock body and is easy to wreck, destroy if also do not cause the lock body internal construction to produce when making external force act on the handle, just should make handle still rotatable one angle of being scheduled to after lock body is locked of lock group.

The utility model content

The utility model purpose is to provide a kind of clutch structure that makes the handle that the lock group is installed can produce the lock of predetermined angular idle running when door lock is locked.

For achieving the above object, solution of the present utility model is: a kind of clutch structure of lock comprises: driving tube, and its inner tubal wall is provided with a hole at least; The key driving tube is loaded on the body inside of this driving tube, is provided with a hole on its tube wall at least; Lateral direction element is installed in the hole of this key driving tube, can mesh with the hole of driving tube; The axial slip element is inserted in this key driving tube, and it is provided with the groove of non axial setting; Rotating element is inserted in this axial slip element, and it is provided with a pin, and this pin stretches in the groove of non axial setting of this axial slip element.

The clutch structure of described lock, driving tube is hollow tubular body, have first end and second end, this first end is installed in lock body structure inside, and this second end connects the connector or the similar item of handle or handle, and is provided with a hole or depression at least in the inner tubal wall of this driving tube; The key driving tube is hollow tubular body, is loaded on the body inside of first end of this driving tube, is provided with a hole on its tube wall at least; Lateral direction element is installed in the hole of this key driving tube, can mesh with the hole of driving tube; The axial slip element is inserted in first end of this key driving tube, and it has first end and second end, is provided with the groove of non axial setting between this first end and second end; Rotating element is inserted in this axial slip element, and it has first end and second end, is provided with a pin between this first end and second end, and this pin stretches in the groove of non axial setting of this axial slip element.
