The chase 113 in one ring week is provided on this second axle 184 between a first end of this barrier assembly 192 and this axle 184.This chase 113 is arranged between this barrier assembly 192 and first, locates this clasp member in this first and can be fixed in this lock housing (will be described hereinafter) at first pair 188 places, hole.This chase 113 can provide a predetermined weakening region, if when it can guarantee that this second lock actuator 104 is removed by brute force, this clasp member will break at these chase 113 places, and it is unaffected to keep this clasp member.Should please note that this chase is not that this barrier assembly 192 of direct next-door neighbour extends to wherein any crack in order to avoid fracture is too near in this member.

This locking mechanism 100 makes up as follows:

Lock cylinder 116,138 can be inserted in their lock actuator housings 114,136 separately.Fasten ring week chase 126 on this lock cylinder 116 by the clasp pin being passed these pin-and-holes 119, then the first lock cylinder 116 can and this first lock actuator housing 114 axially clampings.This second lock cylinder 138 enters this by a circle chuck and is trapped in all chases 150 in the second lock actuator housing 136.

This Compress Spring 152 can be supported on this first lock cylinder 116 in socket, and 154 meetings and these the first lock cylinder 116 clampings of the first clutch component, and makes this drive member 158 these second clutch slot 134 of engaging.The steel connector 160 of simultaneously this sclerosis can be loaded in this scalariform axle 156.The bias voltage of these lock pin 162 these Compress Springs 164 of antagonism flexibly is contained in this scalariform axle 156.

This cam 106 is arranged on the first clutch component 154, and the perforation 178 that the small diameter axle of the second clutch component 166 can be inserted through this cam mesospore 176 abuts against this first clutch time assembly 108.These clutch components 166 can resist the elasticity of Compress Spring 152 and axially move.

This pushes pin 170 to abut against this second clutch component 166, and the second lock cylinder 138 can be used to support this and pushes pin 170.This first lock actuator housing 114 and the second lock actuator shell spare 136 can engage with this clasp member 112.This first axle 182 can be connected with the blind hole 112 of this first lock actuator housing 114, and the second axle 184 can be connected with the blind hole 144 of the second lock actuator housing 136.One group of clasp pin 196 can be threaded in these horizontal perforations 124,146, and engages with the pin-and-hole 186,188 of this clasp member and this mechanism is fixed together.

Should ask understanding, this clutch assembly is removable and make this first clutch component 154 and the second clutch component 166 can axially move to come and can be connected with this cam 106 with selecting in use.This Compress Spring 152 can push these clutch components 154,166 towards the second lock actuator 104.In this way, this drive member 158 can engage the mesospore 176 of this cam 106.Therefore, when a key inserted in this first lock cylinder 116, then its rotation meeting caused the rotation of this first clutch component owing to the engaging between these drive member 158 second clutch slot 134.This then can cause again the rotation of this cam 106, because suitable groove (not indicating among the figure) socket that this drive member 158 and one sets up in this mesospore 176 engages.

On the other hand, if when a key is inserted into this second lock cylinder 138, then one year road can be caused and be pushed pin 170 to this second clutch component 166 to push the first clutch component 154 to release off with the fit of this cam 106 through this to be connected, and makes the groove fit of this drive member 168 and on wall 176 among this cam 106.

In this way, if a key is namely inserted at this place, the first lock actuator place by the inboard of this closure, then this key can be rotated to rotate this cam 106, and thereby can pin or open any locking bolt when this cam lever 174 rotates.Perhaps, if this user is the outside at this closure, then a key can be inserted in the key 148 of this second lock cylinder 138, its can start these clutch components 154,166 and make this drive member 168 these cams 106 of engaging, so this energy is opened by this outside.

Should ask understanding, if this second lock cylinder 138 is removed separately or with the second lock actuator housing 136, then this pushes pin 170 and the second clutch component 166 to drop.This allows that this Compress Spring 152 pushes away the first clutch component 154 and one surpasses pan position that this lock pin 162 can stretch out in this some place, and cover is should the lockpin hole 131 on the first lock cylinder 116 pins this clutch under the bias voltage of this spring 164.This lock pin 162 also can stretch out and pass that this lockpin hole 131 overlaps should the lockpin hole 173 on the camshaft 172.In this way, this cam 106 is now with respect to this first lock cylinder 116 limit of being detained, and make this cam 106 move or remove more difficult.Therefore this cam can be connected with 116 engagings of the first lock cylinder.So, this locking mechanism is invaded in an attempt from the outside people can not rotate this cam 106, because it can be sticked in the first lock actuator 116, can not rotate if it inserts a key internally.

In use, as shown in Figure 2, the safety meeting that additionally augments is provided because of the existence of this barrier assembly 192, and it can extend to this camshaft 172 fully.As described, this barrier assembly 192 can define the cylindric surperficial 194 of a recessed song, its can near and be supported on the cylindric surface of this camshaft 172.So, one security mechanism that augments can be provided because of the following fact: when this second lock cylinder 138 and the second lock actuator housing 136 are removed, one attempt destroys the effractor can not rotate it near this cam lever 174, because this barrier assembly 192 can block the path that reaches this member.Please note that this cam lever 174 range of movement in use is only to rotate 10～15 degree by its normal position, therefore, this barrier assembly 192 can block at least cam 174 of part in all positions in its normal moving range.This can make a people very difficulty enter this cam lever 174 and rotate or remove this cam 106.

As shown in Figure 3, this lock assembly 100 is to be illustrated to be installed in the lock housing 10, and it has a cylinder lock accommodation hole 12.This cam 106 can be in these lock housing 10 interior rotations.As can finding out, if this second lock actuator 104 is removed (in this example this second axle 184 disconnected at chase 113 places and can finish this and remove), then this camshaft 172 can be outstanding by this lock housing 10.And this body 180 and barrier assembly 192 all can be outstanding by this lock housing 10, and stop any approaching the cam lever 174 in this lock housing 10.So, will be not can be gapped or allowance can strongly be entered by an instrument.One guarantees the operation of this cylinder lock is become more difficult with the tight cover credit union in the corresponding moulding hole of this lock housing.

When this locking mechanism 100 during at locking-in state, this cam lever 174 is arranged with this hole 12 misalignment.Therefore this cam 106 can not axially be removed, except non-rotating to unlocking condition.This rotation is impossible, because as previously mentioned, the existing kayser of this cam inserts unless it can not be approached a key internally in this first lock actuator 102.
