This camshaft 172 is generally hollow, is only provided with hole 178 and is defined as and axially runs through except having mesospore 176. This mesospore 176 is shaped as the drive member 158 that can engage this first clutch component 154 in side, or engages the drive member 160 of the second clutch component 166 on the opposite side.

This camshaft 172 can define lockpin hole 173 radially, and it extends through its outer wall.

This clasp component or manacle 112 comprise body 180 to be had the first axle 182 and is axially extended by it, and the second axle 184 is axially to extend to by it on the contrary. This first and second axle 182,184 respectively comprises two pin-and-holes 186,188 etc. respectively. This body 180 has contrary par 190 etc. generally in cylindrical shape at its top and lower surface, and includes the barrier assembly 192 stretched out by it. This barrier assembly can define the part cylindrical surface 194 of concave curved. This body 180 can define the installing hole 181 traversed in order to attach to lock housing. This clasp component 112 is single block.

The chase 113 in ring week is provided on this second axle 184 between this barrier assembly 192 and first end of this axle 184. This chase 113 is arranged between this barrier assembly 192 and at first, and locating this clasp component in this first can be fixed in this lock housing (will be described hereinafter) at hole 188 place of first pair. This chase 113 provides predetermined weakening region, if it ensures that this second lock actuator 104 is when being removed by brute force, this clasp component will in this chase 113 place drop, and it is unaffected to retain this clasp component. Should please note that this chase is not directly next to this barrier assembly 192 in order to avoid fracture is too near to and makes any crack extend to wherein in this component.

This locking mechanism 100 combines as follows:

Lock cylinder 116,138 can be inserted in the lock actuator housing 114,136 of each of which. By the ring week chase 126 clasp pin fastened through such pin-and-hole 119 in this lock cylinder 116, then the first lock cylinder 116 can and this first lock actuator housing 114 axially clamping. This second lock cylinder 138 enters this by circle chuck and is trapped in the second lock actuator housing 136 in all chases 150.

This compression spring 152 can be socketed and be supported in this first lock cylinder 116, and the first clutch component 154 with this first lock cylinder 116 clamping, and can make this drive member 158 engage this second clutch slot 134. The steel connector 160 of this hardening simultaneously can be loaded in this scalariform axle 156. This lock pin 162 is contained in this scalariform axle 156 with resisting the biasing elastic of this compression spring 164.

This cam 106 is arranged on the first clutch component 154, and the small diameter axle of the second clutch component 166 can be inserted through the perforation 178 of this cam mesospore 176 to abut against this first clutch time assembly 108.The elasticity of incompressible spring 152 can axially be moved by such clutch component 166.

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 push pin 170. This first lock actuator housing 114 and the second lock actuator shells 136 can engage with this clasp component 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 second blind hole 144 locking actuator housing 136. Group clasp pin 196 can be threaded in such horizontal perforation 124,146, and engage with the pin-and-hole 186,188 of this clasp component and this mechanism be fixed together.

Should it is understood that, this clutch assembly is removable and make this first clutch component 154 and the second clutch component 166 axially to move and alternatively to be connected with this cam 106 in use. This compression spring 152 can push such clutch component 154,166 to lock actuator 104 towards second. In this way, this drive member 158 can engage the mesospore 176 of this cam 106. Therefore, when key inserts in this first lock cylinder 116, then its rotation can cause the rotation of this first clutch component due to the engaging between this drive member 158 second clutch slot 134. This then can cause again the rotation of this cam 106, because suitable groove (not indicating in the figure) socket that this drive member 158 sets up with in this mesospore 176 engages.

On the other hand, if key is inserted into this second lock cylinder 138, Ze Zai road can be caused and push pin 170 to this second clutch component 166 to push the fit that the first clutch component 154 releases off with this cam 106 to be connected through this, and makes this drive member 168 and the groove fit on the mesospore 176 of this cam 106.

In this way, if key is inserted by the inner side of this closure i.e. this first lock actuator place, then this key can be rotated to rotate this cam 106, and thus can pin when this cam lever 174 rotates or open any locking bolt. Or, if this user is the outside at this closure, then key can be inserted in the key slot 148 of this second lock cylinder 138, and it is understood the such clutch component 154,166 of start and makes this drive member 168 engage this cam 106, therefore this can be opened by outside this.

Should it is understood that, if this second lock cylinder 138 individually or is removed together with second locks actuator housing 136, then this pushes pin 170 and the second clutch component 166 to drop. This allows that the first clutch component 154 is pushed away super pan position by this compression spring 152, can stretch out in this this lock pin 162 of some place, and the lockpin hole 131 in this first lock cylinder 116 of fit pins this clutch under the bias of this spring 164. This lock pin 162 also can extend through this lockpin hole 131 and carry out the lockpin hole 173 on this camshaft 172 of fit. In this way, this cam 106 is now detained limit relative to this first lock cylinder 116, and make this cam 106 move or remove increasingly difficult. Therefore this cam can be connected with the first lock cylinder 116 engaging. So, attempt invades the people of this locking mechanism from outside can not rotate this cam 106, because it can be engaged in the first lock actuator 116, can not rotate if it does not insert a key from inside.

In use, as in figure 2 it is shown, the safety additionally augmented can be provided because of the existence of this barrier assembly 192, it can extend fully into this camshaft 172. As discussed, this barrier assembly 192 can define the cylinder formed surface 194 of concave curved, it is understood against and is supported on the cylinder formed surface of this camshaft 172.So, the security mechanism augmented can be provided because of following true: when this second lock cylinder 138 and the second lock actuator housing 136 are removed, attempt destroys effractor can not rotate it close to this cam lever 174, because this barrier assembly 192 can block the path reaching this component. Please noting that this cam lever 174 range of movement in use is only to be rotated 10��15 degree by its normal position, therefore, this barrier assembly 192 will can block at least part of cam 174 in all positions in its normal moving range. This can make, and people is extremely difficult to be entered this cam lever 174 and rotates or remove this cam 106.

As it is shown on figure 3, this lock assembly 100 is to be illustrated to be arranged in lock housing 10, it has cylinder lock and holds hole 12. This cam 106 can rotate in this lock housing 10. As can be seen, if this second lock actuator 104 is removed (this second axle 184 disconnects at chase 113 place and can complete this and remove in this example), then this camshaft 172 can be highlighted by this lock housing 10. And, this body 180 and barrier assembly 192 all can be highlighted by this lock housing 10, and stop any close to the cam lever 174 in this lock housing 10. So, gap or allowance will not be had strongly to be got enter into by instrument. The tight fit in moulding hole corresponding to this lock housing ensures that the operation to this cylinder lock becomes increasingly difficult.

When this locking mechanism 100 is when locking-in state, this cam lever 174 arranges with this hole 12 misalignment. Therefore this cam 106 can not axially be removed, unless rotated to unlocking condition. This rotation is impossible, because as it was previously stated, this cam now blocks locks in this first lock actuator 102, it can not by close to inserting from inside unless there are key.

As shown in Figure 4, the second locking mechanism 200 is illustrated. This second locking mechanism 200 is similar to the first locking mechanism 100, and similar component has the label more than 100.

This cam 206 is same as cam 106, only except there being flange 302,303 radially to highlight by it in the first lock actuator end.

As it is shown in figure 5, this locking mechanism 200 is illustrated to be contained in lock housing 10, it has locking mechanism hole 12. This lock housing 10 has outside 14 and inner side 16. As can be seen, this first lock actuator 202 is contained in inside this 16, and the second lock actuator 204 is contained in outside this 14.

The flange 302,303 of this cam 206 can inside this 16 places against the outside of this lock housing 10. So, if this second lock actuator 204 be removed, then this cam 206 can not easily be rotated or remove because such flange 302,303 can with this lock housing 10 tight against.

Such flange 302,303 is relative completely on the contrary, and this flange 303 can be aligned with cam lever 274. This can make this cylinder lock mechanism 200 load in this lock housing 10 to be easier to. When this mechanism 200 is when locking-in state, this flange 303 will only against this lock housing 10.

As shown in Figure 6 A and 6B, locking mechanism 400 is illustrated. This locking mechanism 400 comprises the first lock actuator 402, the second lock actuator 404, cam 406, and clutch assembly comprises the first clutch time assembly 408 and the second clutch time assembly 410. This locking mechanism 400 more comprises clasp component 412.

This first lock actuator 402 comprises the first lock actuator housing 414 and the first lock cylinder 416. This first lock actuator housing 414 comprises hollow cylinder 418 and has the projection 420 radially highlighted by it. This cylinder 418 can define two perforations radially extended 419.This projection 420 can define blind hole 422, and it is parallel to this cylinder 418 and partly extends through. This projection 420 more defines a pair horizontal perforation 424.

This first lock cylinder 416 can define one ring week chase 426, an and axially extended key slot 430. This first lock cylinder 416 more defines an axially extended cotter way 431.

This first lock cylinder 416 comprises a pin rotating cylinder mechanism and is adapted to containing key. Key does not provide together with this first lock cylinder 416. Alternatively, refer to that turning assembly 500 can be provided.

This refers to that turning assembly 500 includes finger bolt 502, and it has lever 504 and is connected to the first axle 506, and it can be down to the second axle 508 on rank, shoulder 509 place. This second axle 508 can define groove gap 510, and has a pin-and-hole 512 to be defined to traverse in it. This refers to turn assembly 500 and more comprises key assembly 514 and can rotate this lock cylinder with this lock cylinder 416 fit relative to this housing 414. This key assembly 514 must be fully inserted into this lock cylinder 416 could rotate it, if this key assembly 514 be not fully inserted into this lock cylinder 416, then this lock cylinder 416 can be lockable and can not rotate relative to this housing 414.

This key assembly can define shoulder 515 backward.

This second lock actuator 404 includes the second lock actuator housing 436 and the second lock cylinder 438. This second lock actuator 404 is substantially similar to the second lock actuator 104 of above-mentioned locking mechanism 100, therefore will be not described here in detail.

This first clutch time assembly 408 includes compression spring 452 and the first clutch component 454. This first clutch component 454 can define the drive member 458 radially stretched out by it. Finally, this first clutch component 454 includes radially movable lock pin 462, and it can be biased radially towards by compression spring 464.

This second clutch assembly 410 includes the second clutch component 466, and it comprises scalariform axle and has the drive member 468 radially stretched out by it.

This cam 406 includes generally cylindrical camshaft 472, its have by radially prominent cam lever 474. This cam lever 474 substantially in pushing and drawing shape, can become wider when it is extended away from by this camshaft 472.

This camshaft 472 is substantially in hollow, only except having mesospore (cannot see that) and having a hole to be defined as axially by its traverse. This mesospore is shaped as the drive member 458 that can engage this first clutch component 454 in side, or can engage the drive member 468 of the second clutch component 466 in opposition side.

This camshaft 472 can define the lockpin hole 473 of a radial direction extending through its outer wall.

This clasp component 412 includes body 480 and has the first axle 482 axially extended by it, and the second axle 484 in the opposite direction by axially extend. These each first and second axles 482,484 comprise two pin-and-holes all respectively. Barrier assembly 492 can slide on this second axle 484, and radially prominent close to this body 480 by this axle 484. It is fixed with a pin or rivet 481. This barrier assembly 492 can define the part drum surface 494 of a concave curved. This body 480 can define a transversely mounted hole run through by it, in order to attach to a lock housing.

This locking mechanism 500 combines and operates in the way of being similar to locking mechanism 100 by one, only divided by lower exception.

This refers to turn assembly 500 and is placed in by compression spring 516 on this axle 508 and combines to compress this shoulder 509. This key assembly 514 is disposed through this spring 516 and enters in this groove gap 510. This shoulder 509 can abut against this spring 516.This refers to that bolt assembly 500 can be inserted in this lock cylinder 416, and fixes with sliding pin 518, and it can carry out this key assembly 514 of clasp relative to this axle 508. This sliding pin 518 can slide in this cotter way 431. This spring 516 can compress the surface (cannot see that) in this lock cylinder 416, and bolt 502 can be biased away from this lock cylinder 416 to make this refer to.

Finally, this lock cylinder 416 can be used pair of pin 520 to be fixed in this housing 414, and pin meeting through hole 419 etc. is fastened this chase 426 by this. Therefore this lock cylinder 416 can axially be arrested limit, but can rotate when this key assembly 514 is fully-inserted.

This key assembly 514 is only capable of pushing this and referring to that bolt 502 is fully inserted into by resisting this locking mechanism 500 that is biased towards of this spring 516. So, this locking mechanism would generally be lockable and can not rotate, and inserts in this second latching device 404 unless there are a key or this refers to that bolt 502 is pressed into and rotates.

Therefore, if there being an effractor to destroy this second lock actuator 404, then this cam 406 can not easily be rotated. First, this barrier assembly 492 will stop close to this cam lever 474. Second, this cam 406 can not be rotated, unless this refers to that bolt 502 is pressed, but this is impossible by the outside of this closure.

It should be appreciated that the change case of above-described embodiment can fall all in the scope of the present invention.

Such as, this refers to that bolt is designed to only to extend out to this locked position at predetermined position of rotation. And it can resist the bias of this spring 516 by inside clasp in other positions all.

Additionally, any aspect of the present invention all can be used independently or in combination, and provide the locked instrument of improvement.

In order to increase intensity, various different lock construction elements all can be carried out body plan by some material, for instance high tension steel, kevlar and be different from the complex of conventional sintering component such as pyrite etc.
