Abstract
The utility model discloses a mortise door lock capable of idling by hands, a lock driving element, a bolt and a bolt driving element which can draw back the bolt are disposed in a lock case of the mortise door lock, and a shifting block component which is in linkage with hands is also disposed in the lock case. A driving strap which is capable of rotating the bolt driving element is disposed on the same shaft in the lock case, and the driving strap and the shifting block form a nick. A clutch component is fixedly disposed on the lock case, the clutch component can rotatablely enter the nick to enable the driving strap to link with the shifting block, or the clutch component resets out of the nick. In the technical scheme of the utility model, the shifting block which links with hands is mutually separated from the driving strap which links with the bolt driving element, when the mortise door lock is locked, even though the mortise door lock is rotated by hand strongly, only the shifting block is enabled to idle and the driving strap and the bolt driving element can't transmit force, thereby avoiding the damage of the lock body for over strong force.
Description
[technical field]
The utility model relates to the lockset product scope in the daily necessities, relates in particular to a kind of lock pin lock of handle idle running.
[background technology]
The lock pin lock is that the slotting embedding of a kind of lock body is installed in Men Tingzhong, and its handle cladding plate is assembled in the very lip-deep lock of door, locks such as pellet shot from a slingshot mortise door lock or the two flappers of outer dress.Better because of lock pin lock theftproof, be applicable on the house external door and use.The structure of a kind of monolock tongue lock pin lock as shown in Figure 1, shifting part 1 is an integral body, directly links with the dead bolt driving member.This lock body structure is when rotating handle, and the handle power transmission is to shifting block, and shifting block directly affacts the dead bolt driving member, if the dynamics of rotation handle too senior general might cause making lock body to be damaged.
[summary of the invention]
Goal of the invention of the present utility model provides a kind of lock pin lock of handle idle running, and this lock pin lock shifting block separates with driver blade, can protect lock body not to be damaged when rotating handle energetically well.
To achieve the above object of the invention, the utility model proposes following technical scheme:
A kind of lock pin of handle idle running is locked, and is provided with the dead bolt driving member of tapered end driving member, dead bolt and the described dead bolt of regracting in its lock housing, also is provided with the shifting block assembly with the handle interlock in the described lock housing; In the lock housing also with the coaxial rotatable described dead bolt driving member driver blade that is provided with of described shifting block assembly, described driver blade and described shifting block form a breach; One clutch component is fixedly arranged on lock housing, and described clutch component is rotatable to be entered described breach and make described driver blade and described shifting block link, and perhaps resets outside described breach.
Wherein, described clutch component comprises clutch turning cylinder and clutch part return spring, and described tapered end driving member is positioned at described clutch component below, described clutch component is rotated enter described breach.
As can be seen from the above technical solutions, in the technical solutions of the utility model, be separated from each other, and be provided with clutch component and make and activity to link between described shifting block and the described driver blade with the shifting block of handle interlock with the driver blade of dead bolt driving member interlock.When lock pin lock locking, the tapered end driving member with power transmission in clutch component, make clutch component produce the breach between described shifting block and the described driver blade, even rotating energetically, handle also only make shifting block dally, can not power transmission in driver blade and dead bolt transmission component, avoid lock body because of stressed excessive the damage.
[description of drawings]
Fig. 1 is the structure chart of a kind of monolock tongue lock pin lock in the prior art;
Fig. 2 is the lock pin lock locking states structure chart of the utility model handle idle running;
Fig. 3 locks non-locking states structure chart for the lock pin of the utility model handle idle running.
[specific embodiment]
Below in conjunction with specific embodiment the utility model is described further.
Fundamental technics design of the present utility model is, to separate with the shifting block of handle interlock with the driver blade of dead bolt driving member interlock, the substitute is the clutch component that an activity is set, when the lock pin lock is in non-closure state, described clutch component is rotated the breach that enters between described shifting block and the described driver blade, makes can movable to link between described shifting block and the described driver blade; When lock pin lock locking, the tapered end driving member in clutch component, makes clutch component produce power transmission, also only makes shifting block dally even handle rotates energetically, can not power transmission in driver blade and dead bolt transmission component, avoid lock body because of the stressed excessive purpose of damaging thereby reach.
Referring to figs. 2 and 3, a kind of lock pin of handle idle running is locked, and is provided with the dead bolt driving member 5 of tapered end driving member 2, dead bolt 6 and the described dead bolt 6 of regracting in its lock housing, and for reaching the purpose of handle idle running, lock pin lock of the present utility model is gone back:
Also be provided with the shifting block assembly that links with handle in described lock housing, described shifting block assembly comprises shifting block 2 and shifting block return springs 3.
In the lock housing also with the coaxial driver blade 4 that a rotatable described dead bolt driving member 5 is set of described shifting block assembly, described driver blade 4 forms a breach with described shifting block 2.
One clutch component 7 is fixedly arranged on lock housing, and described clutch component 7 is rotatable to be entered described breach and make and perhaps reset described driver blade 4 and described shifting block 2 interlocks outside described breach.Described clutch component 7 comprises clutch turning cylinder 8 and clutch part return springs 9.
In preferred embodiment, described shifting block return springs 3 or clutch part return springs 9 are spring.
For the mode of rotating clutch component 7, generally can adopt when the lock pin locking closes and rotate when being positioned at the tapered end driving member 2 of described clutch component 7 belows, by the rotation of tapered end driving member 2 described clutch component 7 is rotated and enter described breach.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
