Description

A kind of lock head structure of tail item idle running

【Technical field】

The utility model is related to a kind of lock head structures.

【Background technology】

Tapered end is mounted on door leaf, and the tail item on tapered end is inserted into lock body lockhole, and tail item can drive shifting block to open when rotating Open lock body, tail item is typically all flat or square item, and when installation has directionality, but the lockhole position of each lock body is not It is the same, the angle that such tail item is inserted into is also different.It is always to join since the tail item on existing tapered end is all with lock gall Dynamic relationship, the keyhole initial position in lock gall be it is horizontal, in this way installation when the lockhole position of lock body must be adjusted Whole, installation is inconvenient.

【Utility model content】

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of tail item simple in structure, easy for installation The lock head structure of idle running.

To solve the above-mentioned problems, the utility model uses following technical scheme：

A kind of lock head structure of tail item idle running, including lock shell, the lock shell is interior to be equipped with lock gall, it is characterised in that： One end of the lock gall is rotatably connected with tail item, and being equipped in the lock gall can move axially along the lock gall And the clutch block of rotation can be driven by lock gall, the clutch block is equipped with the pushing block that it can be driven to move axially, and described pushes away It is equipped with the first elastic component between block and clutch block, the second elastic component, the tail item are equipped between the clutch block and tail item It is equipped with the first clutch part, the clutch block is equipped with when it is moved axially can be with the of the first clutch part clutch Two clutch parts.

A kind of lock head structure of tail item idle running as described above, it is characterised in that：Described tail one end is equipped with and extend into Installation end face in the lock gall, the lock gall are equipped with the locking plate for blocking the installation end face axial movement.

A kind of lock head structure of tail item idle running as described above, it is characterised in that：The lock gall is equipped with card slot, described Locking plate be equipped with the fixture block for being caught in the card slot.

A kind of lock head structure of tail item idle running as described above, it is characterised in that：First clutch part is from tail item The folded block of upper bending, second clutch part are the notch being inserted into for folded block.

A kind of lock head structure of tail item idle running as described above, it is characterised in that：Described pushing block one end is axially movable Ground is inserted on the clutch block.

A kind of lock head structure of tail item idle running as described above, it is characterised in that：The clutch block is equipped with slide guide item, The lock gall inner wall is equipped with the guide runner that slide guide is stretched into for the slide guide item.

The beneficial effects of the utility model have：When key is not inserted into or is inserted into incorrect, the idle running of tail item is in idle running The installation site of state, tail item will be unaffected, can be rotated with 360 °, therefore regardless of which type of position lock body lockhole is in, It can install, when key insertion is correct, pushing block is pushed, and the first elastic component is not given and squeezed, to push clutch block laterally to squeeze The second elastic component is pressed, after rotating key, lock gall rotation, the first clutch part and the second clutch part combine, and clutch block is made to drive tail item Rotation, it is simple in structure, it is easy for installation.
