Description of the invention: I: Technical field of the invention of the households 3 Field of the invention The present invention relates to a lock mechanism. More specifically, the present invention relates to a safety cylinder lock mechanism. L. BACKGROUND OF THE INVENTION A cylinder lock generally includes a lock mechanism having a first lock actuating member, a second lock actuating member and a rotatable cam disposed therebetween. The lock actuators can be actuated by selectively rotating the cam using a key or a finger bolt. The cam generally includes a cam shaft and a cam rod projecting therefrom. A clutch mechanism within the lock mechanism is actuatable to selectively engage one or the other of the first and second lock actuators. This is because the rotation of the key-actuatable lock actuator is suppressed when the key is not inserted. Thus, for example, if a lock mechanism includes two key lock actuators, the insertion of the key into the first lock actuator will automatically release the path between the second lock actuator and the cam, thereby enabling The cam is rotatable by the first lock actuator. Alternatively, if a key is inserted into the second lock actuator, the clutch will be moved and a carrier path formed between the second lock actuator and the cam. In use, the cylinder lock is housed in a lock housing that includes a mechanism for extending a latch. The cam system is enclosed between the front and rear walls of the housing. As the cam rotates, the cam lever snaps into the latch mechanism to extend and retract the latch to lock and open a closure. This type of cylinder lock is easy to operate without permission. The unlicensed 201135040 action may be activated by removing the cam to rotate the cam (usually external), and is removed by the human capital pick-up mechanism, and the lock will test, the cam Will... break from - the appropriate tool artificial f. If the horse returns to the lock case, the problem will be exacerbated when there is a pick action instead of 1 on the inside of the lock. The convex = breaking can be freely rotated when it is engaged, because the finger is not = the actuator can be rotated. To insert - the key C ^ 'Ming inside] Summary of the invention This test is intended to provide an improved cylinder lock. According to the invention, a cylinder lock is provided, comprising a lock actuating member rotatable in a first lock actuating body, a second lock actuating member 'a lock cam having a camshaft and a cam lever Protruding, the lock cam is disposed between the first and second lock actuators, and is rotatable about the lock axis '-the clutch mechanism is made at any one of the first and second actuating members The i-moving path is formed between the lock cams, where the full position of the towel is where it will be directly engaged without the cam and the first actuating member, so that the cam will be restrained relative to the first actuating member. Advantageously, the cam is restrained from the first lock actuator in that the second lock is more difficult to displace with the cam and inhibits the cam from deviating from its axis. Rotate. According to the second aspect of the present invention, there is provided a lock mechanism comprising a first-lock actuating member, a second lock actuating member, a lock cam having a cam 201135040 and a cam lever protruding therefrom. The first and second lock actuators are rotatable about the lock axis, and the blocking member at least partially covers the cam lever in a direction parallel to the lock axis. Advantageously, the blocking member will make it more difficult to access the firing cam when the external lock actuation is removed by the cylinder lock. Therefore, it becomes more difficult to forcefully rotate the lock cam to open the lock. It is also more difficult to remove the cam by the mechanism. Preferably, the cylinder lock includes a predetermined weakened area on the opposite side of the blocking member toward the cam rod. In this way, when the lock is subjected to a high external force, it will be split in the 4-position, and the member will remain intact and prevent access to the cam. Preferably, the '-connecting member is provided to connect the first and second lock actuators, and the blocking member is defined on the connecting member. Preferably, the attachment member includes an attachment formation for attaching the cylinder lock to a lock housing. Preferably, the weakened area is defined on the connecting member in such a manner that the weakened area is set to have a "critical" load, and the operation of the actuating member will be tilted at the turned position to break the Connecting member. Preferably, the weakened region is a groove formed on the outer surface of the connecting member. Preferably, the weakened zone is defined between the resistive member and a first attachment formation for attaching the connecting member to the first or second actuator. According to a second aspect of the present invention, a lock assembly is provided, comprising a 201135040, a lock cylinder having a first lock actuator 'a second lock actuator' and a lock cam having a cam shaft and a cam lever The lock cam is disposed between the first and second lock actuators and rotatable about a lock axis, and the lock case has a first wall and a second wall, wherein the lock cylinder is attached to the lock Inside the casing, the cam rod is interposed between the first and second walls, and the cam shaft is axially protruded from the first wall. Advantageously, the camshaft projecting from the housing inhibits rotation of the camshaft from its axis and inhibits entry into the interior of the lock. Preferably, the lock cylinder is housed in a lock housing such that the cam lever is interposed between a first and second wall and the cam shaft projects axially from the first wall. Preferably, the blocking member projects from the first wall. In this way, when the lock is broken, the combined projection of the blocking member and the camshaft will fill the entire cylindrical bore, making it very difficult to manipulate the lock. Preferably, the camshaft and the blocking member project to approximately the same position. Preferably, the camshaft and the axial end face of the blocking member are flush. Preferably, the camshaft is axially protruded from the second wall. According to a fourth aspect of the present invention, a cylinder lock includes a first lock actuating member and a second lock actuating member. A lock cam has a cam shaft and a cam rod protruding therefrom. The lock cam is provided. Between the first and second lock actuators and rotatable about a lock axis, wherein the cam shaft defines a latching member projecting radially outwardly for axially abutting against the bearing surface The camshaft is limited to the ground. Advantageously, a retaining member, such as a flange extending from the camshaft, is provided to prevent axial movement and rotation of the cam when the cam is approached by one of the latch actuators . The retaining member will typically abut one of the outer surfaces of the lock housing inside one of the closures. Alternatively, the flange may abut against one of the outer sides of the lock housing on the outside of the closure to prevent the tool from entering the interior of the lock housing. It should be noted that the third and fourth aspects of the present invention are different solutions to the same problem, i.e., breaking the lock and rotating the cam from its axis to the interior of the housing. According to a fifth aspect of the present invention, a finger bolt mechanism for a cylinder lock includes a housing in which a cylinder is mounted, and a finger bolt is coupled to the housing and the cylinder. The cylinder is rotatably fixed relative to the housing in a first state of the mechanism, and in a second state of the mechanism, the cylinder can be wound around a finger if a torque is applied to the finger The main axis is rotationally movable relative to the housing, wherein the finger bolt is axially movable to move the mechanism from the first state to the second state. Therefore, the user must push (or alternatively pull) the finger before turning. Advantageously, providing a push-actuated finger bolt prevents unauthorized rotation of the cam by the outside of the lock when an outer member is removed. Therefore, a cylinder lock that utilizes a finger bolt on the inside is made safer. The finger bolt mechanism according to the fifth aspect is mounted in a cylinder lock comprising: a first lock actuator rotatable together with a first lock actuator housing; a lock cam having a cam shaft and a cam lever Prominently, the lock cam is disposed between the first lock actuator and the finger bolt mechanism and is rotatable about a lock axis; 7 201135040 A clutch mechanism is configured to be at the lock cam and (i) A drive path is selectively formed between the first actuator and (ii) either of the cylinders. Preferably, the clutch mechanism has a safe condition in which it is non-movably snap-fitted to the cylinder. Preferably, the clutch mechanism is configured to move into the safe position when one of the cylinder lock members, preferably the first lock actuator, is removed. In this way, if an attempt is made to break the cylinder entry, the clutch will advance to the safe state to engage the cylinder, and assuming the finger is in the first state, the clutch (and cam) will It is not rotatably fixed to the positioning, and the manipulation of the lock is prevented by human power. After this situation, the authorized user will be able to access the lock via a different path and internally manipulate the finger to change to the second state to open the lock. According to a sixth aspect of the present invention, a cylinder lock is provided, comprising a lock case and a lock cylinder rotatably mounted in the lock case. Wherein the lock cylinder defines a radially extending surface that is snapped by a fastening element that projects radially inwardly within the lock housing. Advantageously, providing such a device increases safety and is advantageous over, for example, holding the lock cylinder with a round clip. This device occupies less space than a round clamp fastening device, so the lock cam can be made longer, reducing its ability to rotate away from its axis within the lock housing. Further, a groove for receiving a fastening member that defines the radially extending surface can be disposed in the lock actuator housing. Unlike the round clamp device, the round clamp pocket must be disposed just outside the casing. These grooves act as stress-generating parts in the lock cylinder, so if the groove is placed in the casing, it will be less likely to be damaged by external forces. Therefore the cylinder lock will be made safer. Preferably, the fastening element is a pin extending through a wall of the lock housing. Preferably, another securing member is provided at a different circumferential position to project radially inwardly of the interior of the lock housing. Preferably, three such fastening elements are provided and equally spaced about the circumference.

Embodiment 3 Referring to FIG. 1 , a lock mechanism 100 includes a first lock actuator 102 , a second lock actuator 104 , a cam 106 , and a clutch assembly including a first A clutch sub-assembly 108 and a second clutch sub-assembly 110. The lock mechanism 100 further includes a latching member 112. The first lock actuator 102 includes a first lock actuator housing 114 and a 201135040 first lock cylinder 116. The first lock actuator housing 114 includes a hollow cylinder 118 having a projection 120 projecting radially therefrom. The cylinder 118 defines two radially extending through holes 119. The bump 12 defines a blind hole 122 extending partially parallel to the barrel 118. The bump 120 further defines a pair of transverse perforations 124 and the like. The first lock cylinder 116 includes a pin barrel mechanism that can be adapted to receive a key. The first lock cylinder 116 is rotatable within the first lock actuator housing 114 when a suitable key is inserted. When a key is not inserted into the first lock cylinder 116, the lock cylinder cannot be rotated relative to the first lock actuator housing 114. The operation of the locks is generally known in the art. Said. The first lock cylinder 116 defines a circumferential groove 126', an axially extending keyway 130, a first clutch groove 132, and an opposite second clutch groove 134, both of which are One end of U6 extends axially. The first lock cylinder 116 also defines a radially extending lock pin hole 131. The second lock actuator 1〇4 includes a second lock actuator housing 136 and a first lock 138. The second lock actuator housing 136 is substantially similar to the first lock actuator housing and includes a cylinder 140 and a projection 142 extending radially therefrom. The s-high bump 142 defines a blind hole 144, a pair of transverse perforations 146, and the like. . The hex-lock 138 can also be rotated within the second lock actuator housing 136 that is received in a 5 key slot 148. The second lock cylinder 138 will have a circumferential pocket groove 150, and when the second lock cylinder 138 is placed in the second lock actuator housing 136 (four), the second lock actuator shell will be The cylinder 14 of the body 136 projects out. The °C-clutch subassembly 108 includes a compression spring 152 and a first 10 10130350 coupling member 154. The first clutch member 154 includes a stepped shaft 156 having a drive member 158 extending radially from a larger diameter portion thereof. The first clutch member 154 further includes a cylindrical toughened steel plug 16 mounted in one of the axial openings. Finally, the first clutch member 154 includes a radially moveable lock pin 162 that is biased radially outward by a compression spring 164. The clutch assembly 110 includes a second clutch member 166 having a stepped shaft and a drive member 168 extending radially therefrom. The second clutch assembly 110 further includes a push pin 170 axially mounted against the larger diameter portion of the second clutch member 166. The cam 106 includes a generally cylindrical cam shaft 2 having a cam rod 174 projecting radially therefrom. The cam lever 4 is generally pushed and pulled to become wider when it is extended by the cam shaft 172. The camshaft 172 is generally hollow except that it has a central wall 6 provided with a bore 178 defined to extend axially therethrough. The middle wall 176 is shaped to engage the drive member 158 of the first clutch member 154 on one side or the drive member 160 of the second clutch member 166 on the opposite side. The camshaft 172 defines a radial locking pin bore 173 extending through its outer wall. The latching member or restraint 112 includes a body 180 having a first shaft 182 extending axially therefrom and a second shaft 184 extending axially therefrom in an opposite direction. The first and second shafts 182, 184 each include two pin holes 186, 188, and the like. The body 180 is generally cylindrical and has opposite flat portions 190 and the like on its top and bottom surfaces and includes a stop member 192 extending therefrom. The blocking element defines a concave curved partial cylindrical surface 194. The body 180 defines a transverse mounting aperture 181 for attachment to a lock housing. The buckle 11 201135040 member 112 is a single-block. A circumferential groove 113 is provided on the second shaft 184 between the dam member 192 and the "end" of the shaft 184. The recess, such as 3, is positioned between the resist 70 member 192 and the first point. At the first point, the latching member will be positioned at the first pair of holes 188 (which will be made later). The groove (1) provides a pre-(four) weak dip field, and the ride ensures that if the second lock actuator 104 is strongly removed, the retaining member will break at the groove 113 and retain the retaining member Not affected. It should be noted that the groove is not directly adjacent to the blocking element 192 to prevent the fracture from being too close to the member to cause any crack to extend therein. The lock mechanism 1 is assembled as follows: The lock cylinders 116, 138 are inserted into their respective lock actuator housings 114, 136. By snapping the fastening pin through the pin holes 119 to the circumferential groove 126 on the lock cylinder μ, the first lock cylinder 116 is axially engaged with the first lock actuator housing U4. The lock cylinder 138 is held in the second lock actuator housing 136 by the round collet. The compression magazine 152 is sleeved against the first lock cylinder 116, and the first clutch member 154 is engaged with the first lock m, and the movable member 158 is engaged with the second clutch groove 134. At the same time, the hardened steel plug 16 〇 will be loaded into the Hess Fs-like shaft 156. The lock pin 162 is resiliently mounted within the stepped shaft 156 against the offset of the shrink spring 164. The cam 106 is disposed on the first clutch member 154, and the smaller diameter shaft of the second clutch member 166 is inserted through the through hole 178 of the cam middle wall 176 to abut the first clutch sub-assembly. 1〇8. The clutch members 166 are axially movable against the elasticity of the 12 201135040 anti-compression spring ί52. The push pin m is abutted against the second clutch member 166, and the first scale member 136 is engaged with the buckle member 112. The first shaft 182 will engage with the blind hole ι 2 of the first lock actuator housing u4 and the second shaft 184 will engage with the blind hole 144 of the second lock actuator housing 136. - The buckled pin 196 is worn by the hole 124, and is engaged with the pin holes 186, 188 of the fastening member to secure the mechanism. It should be understood that the clutch assembly can be moved using the Japanese temple to move the first clutch member 154 and the second clutch member 166 (four) to the ground to selectively engage the cam 106. The compression spring 152 urges the clutch members 154, I66 toward the second lock actuator 104. In this manner, the drive member 158 will engage the middle wall 176 of the cam 106. Therefore, when a key is inserted into the first lock cylinder H6, its rotation causes the first clutch member to rotate due to the engagement between the second clutch grooves 134 of the drive member 158. This in turn causes rotation of the cam 106 because the drive member 158 is snap-fitted with a suitable recess (not shown) formed in the central wall 176. On the other hand, if a key is inserted into the second lock cylinder 138, a load path is caused to pass through the push pin 17 to the second clutch member 166 to urge the first clutch member 154 to release The sleeve of the cam 106 engages to engage the drive member 168 with a recess in the wall 6 of the cam 1〇6. In this manner, if a key is inserted from the inside of the closure, i.e., where the first lock actuator is located, the key can be rotated to rotate the cam 106 and thus can be locked while the cam lever 174 is rotated. Or open any locks. Or 13 201135040, if the money is outside the __ H key can be inserted into the key slot 148 of the first lock cylinder 138, which will actuate the clutch members 154, 166 to make the drive member 168 card The cam 1〇6 is closed so that the door can be opened by the outside. It is understood that if the second lock cylinder 138 is removed alone or with the second lock actuator housing 136, the push pin l7Q and the second clutch member are disengaged. This allows the __spring 152 to push the first clutch member 154 into an ultrapure position. At the fulcrum point, the hai lock pin will protrude under the bias of the elastic phthalocyanine (10), and fit the lock-up 131 on the first job 116. The lock will also extend out through the The locking pin hole 131 fits the locking pin hole 173 on the cam shaft 172. In this manner, the cam 1G6 is now (four)' relative to the first locking cylinder 116 to move or remove the cam gamma. Therefore, the cam S is engaged with the first lock cylinder 116. Thus, an attempt is made to invade from the outside. The person of the lock mechanism cannot rotate the cam touch because it is engaged with the first lock actuator 116. If it is not inserted from the inside - the key will not turn. In use, as shown in Fig. 2, additional added security may be provided by the presence of the blocking member 192, which will extend completely to the camshaft 172 as described. 92 will define a concave curved cylindrical surface (10) which will be placed on a cylindrical surface that bears against the camshaft (7). Such a full mechanism will be provided by the fact that when the second lock cylinder 138 and the first lock actuator shell rib are removed, an attempt to destroy the intruder will not be able to approach the cam lever m to rotate it. Because the blocking element 192 will support the passage of the component. Please note that the range of motion of the cam lever m when using 14 201135040 仅 is only 10 to 15 degrees from its normal position, so the blocking element 192 will block at least part of it in all positions within its normal range of motion. Cam 174. This makes it extremely difficult for a person to enter the cam lever 174 and to rotate or remove the cam 1〇6. Referring now to Figure 3, the lock assembly 100 is shown mounted within a lock housing 10 having a cylinder lock receiving aperture 12. The cam 106 is rotatable within the lock housing 10. As can be seen, if the second lock actuator 104 is removed (in this example the second shaft 184 has been broken at the groove 113 to complete the removal), the camshaft 172 will be The lock case 10 protrudes. Moreover, both the body 18 〇 and the blocking member 192 will protrude from the lock housing 10 to prevent any access to the cam lever 174 in the lock housing 1 。. So there will be no gaps or tolerances that can be accessed by a tool. A tight fit of the corresponding styling hole with the lock housing ensures that the handling of the cylinder lock becomes more difficult. When the lock mechanism 100 is in the locked state, the cam lever 174 is misaligned with the hole 12. Therefore the cam 106 cannot be removed axially unless it is rotated to an unlocked state. This rotation is not possible because, as previously described, the cam is now locked to the first lock actuator 102, which cannot be accessed unless a key is inserted from the inside. Referring to Figure 4, a second lock mechanism 200 is shown. The second lock mechanism 200 is similar to the first lock mechanism 1 〇〇, and similar members may have a number greater than 100. The cam 206 is identical to the cam 106 except that the flanges 3, 2, 303 project radially from the end of the first lock actuator. Turning to Figure 5, the lock mechanism 200 is shown mounted within a lock housing 1〇 15 201135040 having a lock mechanism aperture 12. The lock housing 1 has an outer side 14 and an inner side 16. As can be seen, the first lock actuator 2〇2 is attached to the inner side 16, and the second lock actuator 204 is attached to the outer side μ. The flanges 302, 303 of the cam 206 will abut the outer side of the lock housing 10 at the inner side 16. Thus, if the second lock actuator 204 is removed, the cam 206 cannot be easily rotated or removed because the flanges 302, 303 will abut the lock housing 10. The flanges 302, 303 are diametrically opposed and the flanges 3〇3 are aligned with the cam bars 274. This makes it easier to fit the cylinder lock mechanism 2 into the lock housing 1〇. When the mechanism 200 is in the locked state, the flange 3〇3 will only abut the lock housing 10. Referring to Figures 6A and 6B, a lock mechanism 4 is shown. The lock mechanism 4 includes a first lock actuator 402, a second lock actuator 404, a cam 406, and a clutch assembly including a first clutch sub-assembly os os and a second clutch sub-assembly. 410. The lock mechanism 4 further includes a latching member 412. The first latch actuator 402 includes a first lock actuator housing 414 and a first lock cylinder 416. The first lock actuator housing 414 includes a hollow cylinder 418 with a projection 420 projecting radially therefrom. The cylinder 418 defines two generally extending through holes 419. The bump 420 defines a blind hole 422 extending partially parallel to the cylinder 418. The bump 420 further defines a pair of transverse perforations 424. The first lock cylinder 416 defines a circumferential groove 426 and an axially extending key groove 43. The first lock cylinder 416 further defines an axially extending pin slot 431. 16 201135040 The first lock cylinder 416 includes a pin drum mechanism adapted to receive a key. A key is not provided with the first lock cylinder 416. Alternatively, a one-finger assembly 500 will be provided. The finger-to-turn assembly 500 includes a finger 502 having a lever 504 coupled to a first shaft 506' which is stepped down to a second axis 508 at a shoulder 509. The second shaft 508 defines a slot 510' and has a pin bore 512 defined across it. The fingering assembly 5 further includes a key member 514 that can be engaged with the lock cylinder 416 to rotate the lock cylinder relative to the housing 414. The key member 514 must be fully inserted into the lock cylinder 416 to rotate it. If the key member 514 is not fully inserted into the lock cylinder 416, the lock cylinder 416 can be locked from rotating relative to the housing 414. The key element defines a rearward shoulder 515. The second lock actuator 404 includes a second lock actuator housing 436 and a second lock cylinder 438. The second lock actuator 4〇4 is substantially similar to the second lock actuator 104 of the aforementioned lock mechanism 100 and will not be described in detail herein. The first clutch sub-assembly 408 includes a compression spring 452 and a first clutch member 454. The first clutch member 454 defines a drive member 458 that projects radially therefrom. Finally, the first clutch member 454 includes a radially movable latch 462 that is biased radially outward by a compression spring 464. The second clutch assembly 410 includes a second clutch member 466 that includes a stepped vehicle i and a drive member 468 that projects radially therefrom. The cam 406 includes a generally cylindrical cam shaft 472 having a cam rod 474 projecting radially therefrom. The cam lever 474 is generally pushed out and becomes wider when it is extended by the cam shaft 472. 17 201135040 The camshaft 472 is generally hollow except that it has a middle wall (not visible) and has a hole defined to pass axially therethrough. The middle wall is shaped such that the drive member 458 of the first clutch member 454 can be engaged on one side, or the drive member 468 of the second clutch member 466 can be engaged on the opposite side. The camshaft 472 defines a radial locking pin bore 473 extending through its outer wall. The retaining member 412 includes a body 480 having a first shaft 482 extending from the vehicle to the ground and a second shaft 484 extending axially therefrom in an opposite direction. Each of the first and second shafts 482, 484 respectively includes two pin holes. A blocking element 492 is slidable over the second shaft 484 and is radially projecting from the body 484 by the shaft 484. It is fixed with a pin or rivet 481. The blocking element 492 defines a concave curved partial cylindrical surface 494. The body 480 defines a transverse mounting aperture therethrough for attachment to a lock housing. The lock mechanism 500 is assembled and operated in a manner similar to the lock mechanism 100 with the following exceptions. The fingering assembly 500 is assembled by placing a compression spring 516 on the shaft 508 to press against the shoulder 509. The key element 514 is disposed through the spring 516 into the slot 510. The shoulder 509 will abut the spring 516. The finger latch assembly 500 is inserted into the lock cylinder 416 and secured by a slide pin 518 which will hold the key member 514 relative to the shaft 508. The slide pin 518 is slidable within the pin slot 431. The spring 516 will press against a surface (not visible) in the lock cylinder 416 such that the finger 502 will be biased away from the lock cylinder 416. Finally, the lock cylinder 416 is secured within the housing 414 18 201135040 using a pair of pins 520 that will pass through the apertures 419 or the like to snap into the recesses 426. Therefore, the lock cylinder 416 is axially restrained, but can be rotated when the key member 514 is fully inserted. The key member 514 can only be fully inserted by pressing the biasing force against the spring 516 toward the lock mechanism 5 to push the finger bolt 5〇2. As such, the lock mechanism will typically be locked from rotation unless a key is inserted into the second latch mechanism 404 or the finger latch 502 is pressed and rotated. Therefore, if an intruder breaks the second lock actuator 4〇4, the cam 406 cannot be easily rotated. First, the blocking element 2 will prevent access to the cam lever 474. Second, the cam 4〇6 cannot be rotated unless the finger 502 is pressed, but this is not possible from the outside of the closure. A variation of the above-described real-time closure will fall within the scope of the present invention - for example, the finger bolt can be designed to extend only to the locked position at a predetermined rotational position. At all other locations, the bias against the elastomer 516 is held inwardly. Moreover, any aspect of the invention can be used independently or in combination to provide an improved locking device. In order to increase the strength, various lock members can be constructed of certain materials such as high tensile steel, kevlar, and composites different from conventional sintered members such as brass.
