Description

A kind of door lock

The utility model relates to door lock.

The lock core of at present popular rolling gate door lock has two-way key hole, at Men Nei or all can insert key unlocking outdoors.Lock core all to insert from both sides key then effective tooth (or pit) of key repeat with cooperating of lock core.Because the profile of tooth of key and lock core repeating part can not change, and just greatly reduces the profile of tooth varied number of key, promptly the key rate is very low.This class can two-way slotting key the key rate of lock be lower than 125 sections, the phenomenon that the key of the rolling gate door lock of shop, Shi Youyi row street can be unblanked mutually, it is poor that its safety is disliked.Also some all must two lock cores of use with the lock of key inside and outside can door, and its cost is higher.In fact in door, have little significance with the key switch door lock.Because even without instruments such as keys also available screwdriver lock is taken apart if the robber is locked in the door; If situation about need promptly run away takes place in owner in door, have under desperation key also difficulty unblank, it is inconvenient to use.

The purpose of the utility model be provide a kind of outdoors with key in door with bat-handle switch door lock, guaranteeing key spoon rate height, safe in utilization and door lock easily.

Be equipped with by shifting block in door lock described in the utility model, the lock body and drive telescopic dead bolt, be equipped with in the tapered end that a side outdoors of lock body is protruded and insert the rotating lock core of key, key hole runs through lock core, there is axle sleeve to link to each other with shifting block, axle sleeve side in door is stretched out lock body and is connected handle, the hole of axle sleeve is over against lock core, a pellet is housed in the axle sleeve, pellet is connected with the protruding chain of axle sleeve, be that pellet can vertically move in axle sleeve but can not relatively rotate, lock core one end that leans on of pellet has the slot that can insert key bit, and the other end of pellet props up a stage clip.

Described door lock, a handle that is in the door links to each other with shifting block by axle sleeve, and turning handle promptly rotates shifting block and can drive dead bolt and move.Can run through lock core at the key that inserts outdoors, key bit is inserted in the slot of pellet, key then drives axle sleeve by pellet and rotates, and finally stirs dead bolt and moves.Because key hole and lock core decentraction, and its rotational angle of handle that once rotated in door not necessarily changes 360 ° on foot, make the slot of pellet not align key hole, then key bit can not insert and make key not be inserted into the end in the slot of pellet and can not rotate, but can move behind the pellet and guarantee that key can be inserted into the end along the axle sleeve length travel because of pellet, rotatable, when key turns when aligning slot, the stage clip that pellet pushes against will promote pellet and promote to the key direction, make it slot and cooperate with key; Being rotated further key again can unblank or lock.

Described door lock is used handle in door, easy to use can opening or lock with key outdoors, because lock core can only insert key from a direction, its key rate improves greatly, can reach more than 6000 sections, and safety is good.

The partial sectional view of the described door lock of Fig. 1, and key aligns the slot state diagram;

The partial sectional view of the described door lock of Fig. 2, and key does not align the slot state diagram;

The partial sectional view of the described door lock of Fig. 3, and key does not align the slot state diagram;

The partial sectional view of the described door lock of Fig. 4, and key does not align the slot state diagram.

Embodiment one, as Fig. 1,2

Shifting block 7 is housed in the lock body 8, and it can stir dead bolt 10 telescopic movings.Be equipped with in the tapered end 4 that a side outdoors of lock body 8 is protruded and insert key 6 rotating lock cores 5, key hole runs through lock core.Axle sleeve 3 one ends link to each other with shifting block 7, the other end is stretched in outside the lock body 8 and is linked to each other with handle 1, the hole of axle sleeve 3 aligns lock core 5, adorn the pellet 9 that a protruding with it key connects in the axle sleeve 3, pellet can vertically move in axle sleeve, lock core 5 one ends that lean on of pellet 9 have the slot 9a that can insert key bit, and the other end of pellet 9 props up stage clip 2.

Fig. 2 is the state that does not align the slot 9a of pellet after key 6 inserts, and pellet 9 moves after being promoted by key, can guarantee that key is inserted into the end.Key to key bit aligns slot 9a, and stage clip 2 promotes pellet 9 reaches, and slot 9a is cooperated with key bit, is Fig. 1 state.

Embodiment two, as Fig. 3,4

The lock that provides by embodiment, if be in the state that the key hole of the slot 9a of pellet and lock core aligns just, can run through the key hole straight cutting to the slot 9a of pellet with bending of front end and the thin metal bar of better rigidity, might stir pellet 9 and rotate and unblank.Be with a protecting cap 11 in lock core 5 the inners, protecting cap 11 1 sides have projection 11a to insert among the key hole 5a, and opposite side has projection 11b can insert among the slot 9a of pellet 9, adorns 12 pairs of protecting caps 11 of a stage clip in the axle sleeve 3 to the lock core 5 direction application of forces.All the other are identical with embodiment one.Fig. 3 is not for inserting key, and stage clip 12 promotes protecting cap 11 and is adjacent to lock core 5.Fig. 4 inserts slot 9a state for the projection 11b that inserts key 6 protecting caps.Even have the hard thing of non-appropriate key protecting cap to be headed among the slot 9a of pellet, can not unblank because of lock core 5 can not change still.
