The specific embodiment

A kind of lock core column 10 and key 11 thereof have schematically been described in the accompanying drawings.Lock core column 10 comprises an outer lock body 12.Lock body 12 has an end face 13.Passage 14 extends to lock body 12 inside from end face 13.Passage 14 has a longitudinal axis 15.What be positioned at passage 14 the inners is a cam coupling 16, and cam 17 is thereon attached by threaded fastener 18.Friction spring 19 is between cam 17 and lock body 12.When lock core column 10 by appropriate key operation and key when axis 15 rotates, cam 17 also around axis 15 rotations so that the lock set that operation links.Coupling 16 has the longitudinal extension groove 20 that cooperates with lock core assembly 21.Therefore lock core assembly 21 is to passage 14 inner extensions so that engage with coupling 16.

Lock core assembly 21 comprises the columniform outer sleeve 22 of a relative thin.Sleeve 22 engages with the face of cylinder 23 around passage 14 of lock body 12 slidably.

Sleeve 22 has a passage 24, holds certain sub 25 in it.Stator 25 is roughly cylindrical and has an end face 26, and passage 27 extends to stator 25 inside from end face 26.Fastener 28 is installed on the stator 25.Sleeve 22 is fixed on the stator 25 and adjacent end face 26 by twisting.

Rotor 29 is positioned at passage 27, and this rotor 29 has an end flange 30.Rotor 29 stretches into passage 27 inside so that flange 30 adjacent end faces 26.Flange 30 has a keyhole 31 that extends to key 32.

Rotor 29 has an interconnection 33, passes it and stretches out a latch 34.Latch 34 is bonded in the groove 20 so that assembly 21 is done angular movement around the angular movement drive coupling 16 of axis 15.When stator 25 adjacent flanges 30, a circlip 35 that is bonded in the groove 36 keeps together assembly 21.

Lock body 12 has the passage 37 that holds pin 38, correctly locatees stator 25 and prevents that it from locking intercropping angular movement 10 error-free running periods at tube thereby pin 38 engages with groove 39 in the stator 25.Lock body 12 also has the passage 40 that holds anti-drill pin 41.

Lock body 12 has a pair of groove 42, and it comprises the angled slot part 43 inner vertical slot parts 59 that stop.Groove 42 and slot part 43 hold the end of pin 34, and it is better illustrated by accompanying drawing 6.Punctual when 44 pairs in key 32 and axis, pin 34 is along axis 44 horizontal expansions, as shown in Figure 6.Yet in a single day sell 34 from position generation angular displacement perpendicular to axis 44, and punctual with 59 pairs of slot parts, and pin 34 does not just stop the 12 inside extractions of lock core assembly 21 self-locking bodies.Yet in the time of in pin 34 is bonded on slot part 43, pin 34 remains on lock core assembly 21 in the lock body 12.

A buckle 45 that comprises fastener 28 is positioned between sleeve 22 and the stator 25 by mooring ground (captively).Fastener 28 comprises a spine 46, and fastener 28 is around its pivot, thereby spine 46 provides a fastener 28 around its axis that " waves " 61.Axis 61 is perpendicular to longitudinal axis 15.

Fastener 28 comprises first junction surface 47, and it stretches in the cannelure 48 of rotor 29.Second junction surface 49, it is bonded in the groove 50 of lock body 12.One spring 51 extends between fastener 28 and stator 25, to push fastener 28 to position shown in Figure 5, that is to say, prevents the position that assembly 21 is extracted out.Fastener 28 can move between the second place that axis 61 pivots at the primary importance and the fastener 28 that assembly 21 are remained in the lock body 12 as shown in Figure 5, so that junction surface 49 no longer is bonded in the groove 50.Therefore fastener 28 permissions remove assembly 21 in lock body 12 when in the second place.When fastener 28 is in its second place and sells 34 punctual with 59 pairs of slot parts, assembly 21 can be drawn out of from lock body 12 inside.Fastener 28 has the part of a cam surface 52 as junction surface 47, and wherein cam surface 52 puts in the cannelure 48.During when key 11 insertions and around axis 15 rotations, key engages and makes fastener 28 to do angular movement (pivot) around axis 44 with cam surface 52.This angular movement is shifted out junction surface 49 in groove 50.This meeting releasing unit 21 is to remove from lock body 12 then.In that, key 11 has the groove 53 of the movable part that holds junction surface 49, so that groove 50 can be left in junction surface 49.

Should be appreciated that for sleeve 22, it has hole 54, junction surface 49 can pass therethrough stretches out; And hole 55, be provided for the passage that pin 38 enters stator slot 39.Stator 25 has groove 39 and can prevent that stator 25 produces angular movement when allowing to remove assembly 21 so that sell 38.

Remove in operation lock core column 10 described above and to insert appropriate key 11 in the process of lock core assembly 21.This key 11 not only has the combination that is used for lock core column 10, and comprises that an end 56 that adds is with engages male wheel face 52.Therefore to be set to the key that is generally used for operable lock 10 from leading edge 58 farther for key shoulder 57.Key 11 is that a kind of improved key is because it also engages with cam surface 52.

Remove in the process of lock core 21 at operation lock 10 described above, insert key 11.Key 11 has a blade sides 59 with needs, and it makes key 11 produce angular movements around axis 15, that is to say, side 59 with moving pin 60 so that allow rotor 29 to do angular movement with respect to stator 25.Then this angular movement with operation of cam face 52 from groove 50, to remove junction surface 49.This angular movement will be alignd with slot part 59 up to pin 34 along angled 43 moving pin 34 in addition.After this assembly 21 can be drawn out of.To carry out inverse operation if will insert lock core assembly 21.

During the normal running of lock core column 10, that is to say that when using a normal key and selling 34 when aliging with slot part 59, buckle 45 remains on assembly 21 in the lock body 12.
