Examples

As shown in fig. 1 and fig. 2, a first embodiment of the present application provides a cylinder blade structure 100, which includes a cylinder core 10, a plurality of blades 20, and at least one locking member 30.

Each blade 20 is movably disposed on the cylinder core 10, each blade 20 can unlock the cylinder core 10 when moving to an unlocking position along an unlocking direction, the plurality of blades 20 includes at least one linkage blade group 201, and the linkage blade group 201 includes at least two linkage blades 202.

Each locking member 30 is movably disposed on the cylinder core 10, all the locking members 30 are configured to limit the respective linkage blades 202 in the linkage blade group 201 to move in respective unlocking directions in sequence according to a preset sequence, and the movement of the previous linkage blade 202 in the unlocking direction thereof can move the locking member 30 to unlock the next linkage blade 202 locked by the locking member 30.

The locking member 30 restricts each linkage blade 202 in the linkage blade group 201, so that each linkage blade 202 in the linkage blade group 202 can only move in the respective unlocking direction in sequence according to a preset sequence, and each linkage blade 202 in the linkage blade group 201 can only be unlocked after the previous linkage blade 202 moves in the unlocking direction. When the technology is unlocked, only after the previous linkage blade 202 is shifted (the previous linkage blade 202 is made to move along the unlocking direction), the next linkage blade 202 can be shifted (the next linkage blade 202 is made to move along the unlocking direction), so that the technology unlocking difficulty is effectively improved.

Note that the last interlocking blade 202 and the next interlocking blade 202 referred to in this application indicate any two interlocking blades 202 that operate in succession, and the last interlocking blade 202 operates first and the next interlocking blade 202 operates later. The unlocking direction of the previous interlocking blade 202 and the unlocking direction of the next interlocking blade 202 may be the same or opposite.

The blades 20 in the key cylinder blade structure 100 may all form the linkage blade group 201, for example, the total number of the blades 20 is six, the number of the linkage blade groups 201 is three, and the number of the linkage blades 202 in each linkage blade group 201 is two; the blades 20 in the key cylinder blade structure 100 may also partially form a linkage blade group 201, for example, the total number of the blades 20 is six, the linkage blade group 201 is one, the linkage blades 202 in the linkage blade group 201 are two, the remaining four blades 20 are non-linkage blades 202, the four blades 20 do not move in a linkage relationship, and each blade 20 in the four blades 20 can be shifted when the lock is unlocked by the technology.

Wherein, lock courage 10 is cylindricly, is equipped with along its axial lockhole 11 of arranging on the lock courage 10, is equipped with a plurality of spouts 12 on the lock courage 10, and spout 12 is followed the radial extension of lock courage 10, and the periphery wall of lock courage 10 is all link up at the both ends of spout 12. The vanes 20 are movably disposed within the chute 12. Of course, one blade 20 may be correspondingly disposed in one sliding chute 12, or a plurality of blades 20 may be correspondingly disposed in one sliding chute 12.

Illustratively, as shown in fig. 1, the blades 20 in the key cylinder blade structure 100 partially form a linkage blade group 201, the linkage blades 202 are in a group, the linkage blade group 201 is correspondingly disposed in one sliding slot 12, the remaining blades 20 are all non-linkage blades 202, and a plurality of non-linkage blades 202 are correspondingly disposed in one sliding slot 12.

The blade 20 is provided with an insertion hole 21 for inserting a key, the insertion hole 21 is rectangular, a protrusion 22 is arranged on the hole wall of the insertion hole 21, and the upper edge of the blade 20 is provided with a bayonet 23. When a correctly shaped key is inserted into the keyhole 11 of the cylinder barrel 10, the key will enter the insertion hole 21 of each blade 20, and the key will contact the protrusion 22 and push the blade 20 to move in its unlocking direction. When each blade 20 moves to its unlocking position along its unlocking direction, and the bayonets 23 on all the blades 20 are aligned and form a strip-shaped groove, at this time, the cylinder 10 can be unlocked.

As shown in fig. 2, a return spring 24 is provided between the blade 20 and the cylinder 10, and when the key is pulled out of the lock hole 11, the blade 20 is returned by the return spring 24.

Furthermore, a guide hole 13 is formed in the lock core 10, the locking member 30 is movably disposed in the guide hole 13, and an elastic member 40 for restoring the locking member 30 is disposed in the guide hole 13.

The guide hole 13 guides the locking member 30 so that the locking member 30 has good stability during movement. The locking member 30 is restored by the elastic member 40 in the guide hole 13.

Illustratively, the resilient member 40 is a spring. One end of the spring is connected to the bottom wall of the guide hole 13, and the other end of the spring is connected to the locking member 30.

Further, the direction in which the locking member 30 moves relative to the cylinder core 10 and the unlocking direction of the blade 20 are perpendicular to each other. In other embodiments, the direction of the movement of the locking element 30 relative to the cylinder barrel 10 and the unlocking direction of the blade 20 may be at an angle other than 90 degrees.

In the key inserting process, each linkage blade 202 in the linkage blade group 201 sequentially moves along the unlocking direction according to the preset sequence, that is, after the previous linkage blade 202 moves along the unlocking direction to unlock the next linkage blade 202, the next linkage blade 202 can move along the preset direction.

Further, when the last link blade 202 is moved to the unlock position in its unlock direction, the lock 30 unlocks the next link blade 202. That is, when the previous linking blade 202 moves in its unlocking direction just to the unlocking position, the next linking blade 202 is unlocked, and when the next linking blade 202 moves in its unlocking direction to the unlocking position, the bayonet 23 of the previous linking blade 202 is aligned with the bayonet 23 of the next linking blade 202.

In other embodiments, the next linkage blade 202 is unlocked even though the previous linkage blade 202 has not moved to the unlocking position in the unlocking direction. In this case, immediately after the next link blade 202 is unlocked, the previous link blade 202 needs to continue to move in its unlocking direction, and finally move to the unlocking position.

The linkage blades 202 in each linkage blade group 201 may be two, three, four, etc. When there are a plurality of interlocking blade groups 201, the number of interlocking blades 202 in each interlocking blade group 201 may be equal or different. For example, there are two linked blade groups 201, two linked blades 202 in one linked blade group 201, and three linked blades 202 in the other linked blade group 201.

In some embodiments of the present application, with continued reference to fig. 2, the linkage blade set 201 includes two linkage blades 202, and one locking member 30 is disposed corresponding to each of the two linkage blades 202. That is, the number of the interlocking blades 202 in the interlocking blade group 201 is two, and one locking member 30 is correspondingly provided for two interlocking blades 202, so that the structure is simple and the realization is easy.

For convenience of description, of the two interlocking vanes 202, the last interlocking vane 202 that operates first is defined as a first interlocking vane 203, and the next interlocking vane 202 that operates later is defined as a second interlocking vane 204.

Further, a stopper is provided on the second linkage blade 204, and the locking member 30 is engaged with the stopper to prevent the second linkage blade 204 from moving in the unlocking direction thereof to lock the second linkage blade 204. The movement of the first linkage blade 203 in the unlocking direction can move the locking member 30 and disengage the stopper portion to unlock the second linkage blade 204.

The locking of the second linkage blade 204 is realized by the locking member 30 engaging with the stopper portion of the second linkage blade 204, and the unlocking is realized by the locking member 30 disengaging from the stopper portion of the second linkage blade 204, so that the locking and unlocking of the second linkage blade 204 can be performed in a simple manner.

Furthermore, the limiting part is a clamping groove 2041 arranged on the second linkage blade 204, the structure is simple, and the locking part 30 can be moved to be conveniently matched with and separated from the clamping groove 2041.

When locking member 30 is inserted into locking groove 2041, second coupling blade 204 is locked, and locking groove 2041 restricts movement of second coupling blade 204 in either the unlocking direction or the direction opposite to the unlocking direction. When the first linking blade 203 moves in its unlocking direction and disengages the locking member 30 from the catching groove 2041, the second linking blade 204 is unlocked.

In other embodiments, the limiting portion may have other structures. For example, as shown in fig. 3, the stopper is a protrusion 2031 provided on the second linkage blade 204, the locking member 30 is in contact with the protrusion 2031, and the locking member 30 functions to prevent the protrusion 2031 from moving in the unlocking direction of the second linkage blade 204, thereby preventing the second linkage blade 204 from moving in the unlocking direction. When the first linkage blade 203 moves in the unlocking direction thereof and disengages the locking member 30 from the protrusion 2031, the locking member 30 no longer prevents the protrusion 2031 from moving in the unlocking direction of the second linkage blade 204, and the second linkage blade 204 is unlocked.

Further, with continued reference to fig. 2, the locking member 30 has a guide slope 31, and the first interlocking blade 203 moves in the unlocking direction thereof to be able to contact the guide slope 31 and push the locking member 30 to move so that the locking member 30 is disengaged from the stopper portion to unlock the second interlocking blade 204.

The guide inclined surface 31 on the locking member 30 can push the locking member 30 to move in the process of moving the first linkage blade 203 along the unlocking direction, so that the locking member 30 is gradually separated from the limiting part, and the mode for moving the locking member 30 is simple and easy to realize.

During the movement of the locking member 30 to unlock the second interlocking blade 204, the locking member 30 moves into the guide hole 13 of the cylinder tube 10, and compresses the elastic member 40 in the guide hole 13.

Further, the first interlocking vane 203 is also provided with a locking groove 2041, and when the locking member 30 locks the second interlocking vane 204, the locking member 30 is simultaneously locked in the locking grooves 2041 of the first interlocking vane 203 and the second interlocking vane 204. The locking member 30 may function to restrict the first linking blade 203 from moving in the direction opposite to its unlocking direction.

In other embodiments, the movement of the first linkage blade 203 to move the locking member 30 may be realized by other structures. For example, as shown in fig. 4, the groove wall of the locking groove 2041 on the first linkage blade 203 is a slope 2032, and during the movement of the first linkage blade 203 in the unlocking direction, the slope of the first linkage blade 203 will contact the locking member 30, thereby pushing the locking member 30 to move and unlocking the second linkage blade 204.

Alternatively, with continued reference to fig. 2, the locking member 30 has a blocking surface 32, and the blocking surface 32 and the guiding ramp 31 are located on opposite sides of the locking member 30. Blocking surface 32 serves to block movement of second coupling blade 204 in its unlocking direction.

The blocking surface 32 and the guide slope surface 31 are respectively located on opposite sides of the locking member 30, since the first interlocking blade 203 moves to be able to contact the guide slope surface 31 and push the locking member 30 to move, and the blocking surface 32 functions to block the second interlocking blade 204 from moving in the unlocking direction thereof, so that the unlocking direction of the first interlocking blade 203 is opposite to the unlocking direction of the second interlocking blade 204. In fig. 2, the unlocking direction of the first linkage blade 203 is leftward, and the unlocking direction of the second linkage blade 204 is rightward.

Wherein the locking member 30 is a block structure. When locking member 30 is engaged in engaging groove 2041 of first coupling blade 203 and second coupling blade 204, second coupling blade 204 is locked, and blocking surface 32 contacts the groove wall of engaging groove 2041 of second coupling blade 204, so that second coupling blade 204 cannot move in its unlocking direction (the direction in which second coupling blade 204 moves to the right in fig. 2).

Optionally, blocking surface 32 is perpendicular to the unlocking direction of second coupling blade 204, and the groove wall of second coupling blade 204 where clamping groove 2041 contacts blocking surface 32 is a plane parallel to blocking surface 32.

In other embodiments, as shown in fig. 5, the unlocking direction of the first linkage blade 203 and the unlocking direction of the second linkage blade 204 may be the same. As shown in fig. 6 and 7, the locking member 30 has a blocking surface 32, the blocking surface 32 is located on the same side of the locking member 30 as the guide slope surface 31, and the blocking surface 32 is used to block the second coupling blade 204 from moving in its unlocking direction.

The blocking surface 32 is located on the same side of the locking member 30 as the guide slope 31, and since the first interlocking blade 203 moves to contact the guide slope 31 and push the locking member 30 to move, and the blocking surface 32 functions to prevent the second interlocking blade 204 from moving in its unlocking direction, the unlocking direction of the first interlocking blade 203 is the same as the unlocking direction of the second interlocking blade 204. In fig. 5, the unlocking direction of the first linkage blade 203 and the unlocking direction of the second linkage blade 204 are both leftward.

Referring to fig. 5 and 7, when locking member 30 is engaged with engaging grooves 2041 of first coupling blade 203 and second coupling blade 204, second coupling blade 204 is locked by locking member 30, and blocking surface 32 contacts the groove wall of engaging groove 2041 of second coupling blade 204, so that second coupling blade 204 cannot move in its unlocking direction (the direction in which second coupling blade 204 moves to the left in fig. 5).

In some embodiments of the present application, as shown in fig. 8, the linkage blade set 201 includes at least three linkage blades 202, and one locking member 30 is disposed for each adjacent two linkage blades 202.

In each adjacent two of the link blades 202, the link blade 202 that moves first is the previous link blade 202, and the link blade 202 that moves later is the next link blade 202.

In the present embodiment, the arrangement of the locking member 30 between each adjacent two of the interlocking blades 202 is the same as the arrangement of the locking member 30 when there are two interlocking blades 202 in the interlocking blade group 201 in the above-described embodiment. That is, in the present embodiment, the structure formed by any three of the adjacent two interlocking vanes 202 and the locking member 30 can be regarded as the structure formed by three of the first interlocking vane 203, the second interlocking vane 204 and the locking member 30 in the above-described embodiment.

With continued reference to fig. 8, taking the linkage vane group 201 as three linkage vanes 202 as an example, for convenience of description, the three linkage vanes 202 are defined as a third linkage vane 205, a fourth linkage vane 206 and a fifth linkage vane 207, and the third linkage vane 205, the fourth linkage vane 206 and the fifth linkage vane 207 are arranged in this order in the axial direction of the cylinder liner 10. The preset sequence of the operations of each interlocking vane 202 in the interlocking vane group 201 is set such that the third interlocking vane 205, the fourth interlocking vane 206, and the fifth interlocking vane 207 operate in sequence. The locking member 30 of the third linkage blade 205 provided corresponding to the fourth linkage blade 206 is a first locking member 301, and the locking member 30 provided corresponding to the fourth linkage blade is a second locking member 302.

For the third linkage blade 205 and the fourth linkage blade 206, the third linkage blade 205 moves in the unlocking direction thereof, so that the fourth linkage blade 206 can move in the unlocking direction thereof only after the first locking member 301 unlocks the fourth linkage blade 206, the third linkage blade 205 is the previous linkage blade 202, and the fourth linkage blade 206 is the next linkage blade 202.

The three structures of the third interlocking blade 205, the fourth interlocking blade 206, and the first locking member 301 are the same as the three structures of the first interlocking blade 203, the second interlocking blade 204, and the locking member 30 in the above embodiment, and will not be described again.

With respect to the fourth linkage blade 206 and the fifth linkage blade 207, the fourth linkage blade 206 moves in the unlocking direction thereof, and after the second locking member 302 unlocks the fourth linkage blade 206, the fifth linkage blade 207 can move in the unlocking direction thereof, the fourth linkage blade 206 is the previous linkage blade 202, and the fifth linkage blade 207 is the next linkage blade 202.

The structure of the fourth interlocking blade 206, the fifth interlocking blade 207, and the second locking member 302 is the same as the structure of the first interlocking blade 203, the second interlocking blade 204, and the locking member 30 in the above embodiment, and the description thereof is omitted.

Illustratively, the unlocking direction of the third linkage blade 205 is opposite to the unlocking direction of the fourth linkage blade 206, and the unlocking direction of the fourth linkage blade 206 is opposite to the unlocking direction of the fifth linkage blade 207. In other embodiments, the unlocking direction of the third linkage blade 205 and the fourth linkage blade 206 may be opposite, and the unlocking direction of the fourth linkage blade 206 and the unlocking direction of the fifth linkage blade 207 may be the same; the unlocking direction of the third interlocking blade 205 may be the same as the unlocking direction of the fourth interlocking blade 206, and the unlocking direction of the fourth interlocking blade 206 may be opposite to the unlocking direction of the fifth interlocking blade 207.

In some embodiments of the present application, as shown in fig. 9, the linkage blade set 201 includes at least three linkage blades 202, and one locking member 30 is disposed for all the linkage blades 202.

Further, the locking member 30 has a plurality of guide slopes 31, and the previous interlocking blade 202 moves in its unlocking direction to be able to contact with its corresponding guide slope 31 and push the locking member 30 to move to unlock the next interlocking blade 202.

The guide slope 31 on the locking member 30 can convert the movement of the previous linkage blade 202 into the movement of the locking member 30, so that the next linkage blade 202 is unlocked, and the movement of the locking member 30 is realized simply and easily.

In this embodiment, each linkage blade 202 is provided with a locking groove 2041 for inserting the locking member 30, and after the locking member 30 is inserted into the locking groove 2041 of the next linkage blade 202, the locking member 30 locks the next linkage blade 202.

Taking the linkage blade group 201 as three linkage blades 202 as an example, for convenience of description, the three linkage blades 202 are defined as a sixth linkage blade 208, a seventh linkage blade 209 and an eighth linkage blade 210, and the sixth linkage blade 208, the seventh linkage blade 209 and the eighth linkage blade 210 are sequentially arranged in the axial direction of the cylinder 10.

In this embodiment, as shown in fig. 10, the locking member 30 has two guiding inclined surfaces 31 and two blocking surfaces 32, the two guiding inclined surfaces 31 are a first guiding inclined surface 311 and a second guiding inclined surface 312, the first guiding inclined surface 311 and the second guiding inclined surface 312 are staggered in the thickness direction of each linkage blade 202, the two blocking surfaces 32 are a first blocking surface 321 and a second blocking surface 322, the first guiding inclined surface 311 and the second guiding inclined surface 312 are located on two opposite sides of the locking member 30, the first blocking surface 321 and the second guiding inclined surface 312 are located on the same side of the locking member 30, and the second blocking surface 322 and the first guiding inclined surface 311 are located on the same side of the locking member 30.

When the locking member 30 is engaged in the engaging groove 2041 of each linking blade 202, the first blocking surface 321 will prevent the seventh linking blade 209 from moving in the unlocking direction (the direction in which the seventh linking blade 209 moves rightward in fig. 9), and the second blocking surface 322 will prevent the eighth linking blade 210 from moving in the unlocking direction (the direction in which the eighth linking blade 210 moves leftward in fig. 9). When the sixth linkage blade 208 moves toward the unlocking direction (the direction in which the sixth linkage blade 208 moves leftward in fig. 9), the sixth linkage blade 208 contacts the first guide slope 311 and pushes the locking member 30 to move until the first blocking surface 321 is separated from the locking groove 2041 of the seventh linkage blade 209, and at this time, the seventh linkage blade 209 can move in the unlocking direction; when the seventh linking blade 209 moves toward the unlocking direction, the seventh linking blade 209 will contact the second guiding inclined surface 312 and push the locking member 30 to move continuously until the second blocking surface 322 is separated from the locking groove 2041 of the eighth linking blade 210, and at this time, the eighth linking blade 210 can move.

As shown in fig. 11, the second embodiment of the present application further provides a lock cylinder 200, which includes a lock case 220, a side post 240, and the lock cylinder blade structure 100 provided in the first embodiment. The cylinder 10 is rotatably disposed in the lock housing 220, and the side post 240 is movably disposed on the cylinder 10. When each blade 20 moves in the unlocking direction to the unlocking position, the jamb 240 moves relative to the cylinder core 10 to unlock the cylinder core 10.

Each of the interlocking blades 202 in the interlocking blade group 201 in the key cylinder 200 can move in the respective unlocking directions only in sequence in a preset order. When the technology is unlocked, only after the previous linkage blade 202 is shifted, the next linkage blade 202 can be shifted. The technical unlocking difficulty of the lock cylinder 200 with the structure is higher.

Wherein, a central hole 2201 is arranged on the lock shell 220, and the diameter of the central hole 2201 is matched with the outer diameter of the lock core 10. The cylinder core 10 is rotatably disposed in the central hole 2201. The cylinder 10 is provided with a slide hole 14, the side post 240 is movably disposed in the slide hole 14, and the side post 240 can move in the slide hole 14 along the radial direction of the cylinder 10. The inner wall of the lock case 220 is provided with a locking groove 2202 into which the side post 240 is inserted.

As shown in fig. 12, when the bayonets 23 of the blades 20 are not aligned, the side posts 240 are inserted into the locking grooves 2202 of the lock case 220, and the blades 20 prevent the side posts 240 from being disengaged from the locking grooves 2202, so that the cylinder core 10 is locked and the cylinder core 10 cannot rotate relative to the lock case 220.

As shown in fig. 13, when a correct key is inserted into the lock hole 11, each blade 20 will move to the unlocking position in the respective unlocking direction, the bayonet 23 on each blade 20 is aligned to form a strip-shaped groove, the jamb 240 will be separated from the locking groove 2202 on the lock housing 220 and clamped into the strip-shaped groove, and at this time, the cylinder 10 is unlocked, and the cylinder 10 can rotate relative to the lock housing 220.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
