Specific embodiments:
The utility model comprises lock housing 1, and rotation axis assembly 2 and lock core assembly 3 are housed in lock housing 1, pulls out and drags 4, and wherein rotation axis assembly 2 is made up of knob 5 and rotation axis 6, and people can drive to dial by manual rotation rotation axis assembly 2 and drag 4 to rotate.Lock core assembly 3 is by lock gall 7, and pellet shot from a slingshot group 8 constitutes, and its effect is to limit to have only by key 9 insertion lock galls 7 to rotate lock gall 7.Rotation axis 6 and lock gall 7 are installed on the same axis in lock housing 1, pull out and drag 4 to be sleeved on the surface, outer garden of lock gall 7 and rotation axis 6, pull out drag 4 vertically by pulling out mesosphere 10 location of dragging on 4.Be provided with driving lever 11 on 4 pulling out to drag, when dialling when dragging 4 to rotate, driving lever 11 is stirred dead bolt (not drawing among the figure) lock is opened.
At rotation axis 6, pull out and drag 4, the connecting portion of lock gall 7 is provided with interstitial hole 14, big spring 15 is housed in the interstitial hole 14 and changes part cover 16, big spring 15 is contained in by rotation axis 6 ends, changeing part cover 16 is contained in by lock gall 7 ends, changeing part cover 16 can slide in hole interstitial hole 14, right-hand member position on the surface, outer garden of changeing part cover 16 is provided with convex tendon 17, have chute 18 pulling out to drag in 4 mesosphere 10 and the lock gall 7, generally, changeing part cover 16 is close to lock gall 7 under the effect of hole inner spring 15, convex tendon 17 is stuck in the chute on the lock gall 7, at this moment, changes part cover 16 and can drag 4 to rotate with respect to dialling.In changeing part cover 16, apical axis 19 and little spring 20 are housed, little spring 20 is enclosed within on the apical axis 19, when key 9 inserts lock gall 7, the roof pressure apical axis 19 left, change part cover 16 and are moved to the left under the effect of spring force, and the convex tendon 17 that changes on the part cover 16 enters mesosphere 10 internal chutes 18, that is to say the convex tendon 17 that changes on the part cover 16 be stuck on the lock gall 7 simultaneously and the chute of mesosphere 10 in, at this moment, when rotating lock gall 7, lock gall 7 drives to dial and drags 4 to rotate together.
Have locating slot 12 (seeing shown in Figure 3) on rotation axis 6, be provided with positioning table 13 on 4 pulling out to drag, positioning table 13 is stuck in the locating slot 12, and when rotation knob 5, rotation axis 6 can drive to pull out and drag 4 rotations.That is to say that rotation axis 6 and pull out and drag 4 to be solidified as a whole all the time just can drive to dial when making manual rotation rotation axis assembly 2 and drag 4 rotations.
Safeties are equipped with in centre at rotation axis assembly 2, safeties comprise button 21, power transmission shaft 22, locating piece 23, alignment pin 24, spring 25, wherein button 21 is connected with the left end of power transmission shaft 22, and spring 25 is contained on the power transmission shaft 22, also is fixed with locating piece 23 on power transmission shaft 22, alignment pin 24 is housed on lock housing 1, and locating piece 23 is provided with inclined-plane and locating surface 26.When pressing the button 21, power transmission shaft 22 drives locating piece 23 and moves right, the inclined-plane of locating piece 23 promotes to move and be stuck on the locating surface 26 on the alignment pin 24, make power transmission shaft 22 location and can not return, at this moment, the right-hand member of power transmission shaft 22 withstands changes part cover 16, commentaries on classics part cover 16 can't be moved to left, therefore, key can only be to drive lock gall 7 and change 16 idle running of part cover, lock can't be opened.When rotation knob 5, rotation axis 6 drives power transmission shaft 22 and locating piece 23 rotates, and makes alignment pin 24 break away from locating surface 26, and power transmission shaft 22 and locating piece 23 return to original position under the effect of spring force.
The utility model in use, in rotation axis assembly 2 ends were contained in, lock core assembly 3 ends were by outdoors, can drive to dial to drag at indoor rotation rotation axis assembly 2 and stir dead bolt, and lock is opened.If outdoor, insert lockhole with key, and rotate lock gall 7, lock gall 7 drives changes 16 rotations of part cover, when the convex tendon 17 that changes part cover 16 is aimed at the chute of mesosphere 10, change part cover 16 and be moved to the left under the effect of spring force, convex tendon 17 enters mesosphere 10 internal chutes, convex tendon 17 be stuck on the lock gall 7 simultaneously and the chute of mesosphere 10 in, lock gall 7 drives to dial to drag lock is opened, when extracting key out, change part cover 16 and under the effect of big spring power, move right, be returned to not duty.If press the button 21 indoor, power transmission shaft 22 withstands changes part cover 16, makes outdoors and also door can't be opened with key.
