Similarly, the third boss 252 of the third blade 25 may contact the side post. Thus, when the first blade 23, the second blade 24 and the third blade 25 are adjusted to the correct positions, the notches in the first notch 233 and the second notch 242 form a linear groove, and at the same time, the third boss 252 in the third blade 25 is completely removed from above the side pillar, and the pressing on the side pillar is released. The side posts are bounced by the elastic force of the spring and completely enter the side post grooves 226 of the cylinder core 2 and the linear grooves of the blades. At this time, the cylinder 2 can be rotated, the lock cylinder 1 is unlocked, and the lock cylinder 1 can be opened. During locking, the jamb snaps into the jamb recess 226 of the cylinder 2 and the linear recess of the housing of the cylinder 1, preventing the cylinder 2 from rotating in the housing.

When looking at the two end surfaces of the lock core 2, the widths of the first blade 23, the second blade 24 and the third blade 25 are two thirds or more than two thirds of the widths of the first groove 211, the second groove 212, the third groove 213, the fourth groove 221, the fifth groove 222 and the sixth groove 223. The inner diameter width of the straight concave hole 216 is a little more than one third or one third of the first groove 211, the second groove 212, the third groove 213, the fourth groove 221, the fifth groove 222 and the sixth groove 223. The positions of the straight concave holes 216 are distributed in an arrangement with the central positions above the first groove 211, the second groove 212 and the third groove 213.

Also, in the first to sixth grooves 211 to 223, the width of the through hole 28 is the same as that of the straight recess hole 216, or slightly larger than that of the straight recess hole 216.

Thus, in the process that the first blade 23, the second blade 24 and the third blade 25 are sleeved in the first groove 211, the fourth groove 221, the second groove 212, the fifth groove 222, the third groove 213 and the sixth groove 223 to move left and right, two thirds of the width of the blades always forms a shielding effect in the area of the through hole 28. Because the width of the through hole 28 area or straight recess 216 is only one third of the groove width. Thus, the positional distribution of the notches in the probe blade is prevented from being read by a probe tool such as a technical unlocking tool or an iron bar after entering the through hole 28 through the straight recessed hole 216.

More specifically, the side column is a long strip column structure, and the cross section of the side column is composed of a polygon and a triangle, and is usually a combination of the square and the triangle. Or the cross section of the side column is a combination of rectangle and triangle. The side of the side column is a cuboid with a concave structure, and the convex parts at the two ends of the long strip are respectively connected with the first blade 23 and the third blade 25. And, the depressed area in the middle of the third groove 213 in the pick 31 is used to connect the second leaf 24. The length of the protruding portions at the two ends of the side column is set according to the length required by the first blade 23, the third blade 25 and the connecting third groove 213. The length of the recessed area of the edge posts is determined by the length of second blade 24.

And, the connecting groove portion and the head portion 321 of the key 32 are connected to each other. Wherein, the end of the key rod 322 at the end connected with the head 321 of the key 32 is a triangular structure 323 or a bevel edge structure.

The triangular structure 323 or the hypotenuse structure at one end of the key rod 322 of the key 32 is used to move the right through hole 231 and the left through hole 232 of the first blade 23 to the two sides for pushing apart. The open section 3241 is a groove in the shape of an opening opened outward. Which is used to fully collapse the first post 241 of the second blade 24 and the second plurality of posts 251 of the third blade 25 into the return section 3242 and into the curved section 3243. The key 32 allows the first boss 241 in the second blade 24 and the second boss 251 in the third blade 25 to perform the correct positional movement in the curved section 3243, allowing the notch in the blades to be located directly above the side posts. When the key 32 is fully inserted into the cylinder core 2 of the lock cylinder 1, the first blade 23 is rebounded by the spring into the concave reset groove 3244 of the key rod 322. Under the condition that the first blade 23 is completely inserted into the key rod 322, the first blade 23 returns by the spring to block the locking hole 291 of the lock cylinder 1. After unlocking, the key 32 is pulled out from the key cylinder 1, and at this time, the first blade 23 and the third blade 25 are returned by the spring. The second blade 24 is positionally displaced by the key 32 returning to the groove of section 3242. Generally, the groove of the return section 3242 is a linear groove located at a position intermediate the key lever 322. When the locking hole 291 is returned to the original position, the first protrusions 241 of the second blade 24 and the second protrusion 251 of the third blade 25 are completely moved to the center of the locking hole 291.

The third blade 25 has a second convex column 251 on the top side and a convex third convex column 252 on the bottom side. When the lock is not unlocked, the third convex column 252 is pressed on the surface of the side column, and the side column is in a locking state. When the lock is unlocked, the second convex column 251 is moved, the third convex column 252 in the third blade 25 is moved away from the surface of the side column, and the side column bounces up to enter the bottom edge part without the bulge of the third blade 25, so that the unlocking is completed.

Specifically, the first blade 23, the second blade 24, and the third blade 25 in the key cylinder 1 are sequentially arranged and overlapped from the outside to the inside. The first blade 23 and the third blade 25 are the same height. The first blade 23 and the third blade 25 have a height greater than or equal to the height of the second blade 24. In the lock core 1, at least one piece of first blade 23 is mutually supported with third blade 25, presses and the locking to the side post simultaneously, prevents that side post one end from bounceing alone or perk.

The second blades 24 are a plurality of blades or a plurality of groups of blades arranged with each other. To satisfy a sufficient key amount, the second blade 24 is typically no less than 24 blades. When the lock is not opened, the plurality of second blades 24 are distributed in disorder.

The third blade 25 is at least one blade. Wherein, as required, the first blade 23 can be provided with a plurality of sets of locking blades in the lock core 2, and the third blade 25 can be provided with a plurality of blades in the lock core 2. Wherein, the side edges of the first blade 23 and the third blade 25 are in a vertical line-shaped plane structure. If desired, the first blade 23 and the third blade 25 may be formed with a side edge like a multi-fold line protruded from the surface of the second blade 24.

Specifically, when the lock is not unlocked, the first notch 233 in the first blade 23 and the second notch 242 of the first blade 23 are located right above the side posts, and are in the unlocked state. The left through hole 232 and the right through hole 231 in the two first blades 23 overlap each other at the center line position of the lock hole 291 of the key cylinder 1. A through hole 28 with a gap of not more than 3mm in diameter is left at the locking hole 291. Generally, the through hole 28 formed in the overlapping area between the left through hole 232 and the right through hole 231 has a hole diameter smaller than the maximum moving distance of the first protrusion 241 and the second notch 242 of the second blade 24. The remaining portions of the two first blades 23 are shielded from each other by the non-through hole 28 region other than the left through hole 232 or the right through hole 231.

When the lock is not unlocked, the second notches 242 in the second blade 24 are randomly arranged, and the first bosses 241 in the second blade 24 are also randomly arranged. The bottom edge of the second blade 24 and the third convex column 252 in the third blade 25 are positioned above the side columns and are in a pressing locking state with the side columns. The side posts are prevented from bouncing up from the first recess 211 of the housing completely into the third recess 213 of the cylinder core 2.

Thus, when the lock is not unlocked, the first blade 23 is in the unlocked state, and the side posts can be sprung into the first notch 233 of the first blade 23 and the second notch 242 of the first blade 23. However, the second blade 24 and the third blade 25 are in a locked state, and the side columns are pressed by the bottom edge of the second blade 24 and the third protruding column 252 of the third blade 25, and cannot be bounced into the first notch 233 of the first blade 23 and cannot be bounced into the bottom edges of the third blade 25 which are not protruded at two sides. Meanwhile, when the first vane 23 is in the unlocked state, the right through hole 231 in the first vane 23 and the left through hole 232 in the first vane 23 form a sealed-off state at the lock hole 291 of the key cylinder 1. When the first blade 23 is in the unlocked state, the first blade 23, the second blade 24, and the third blade 25 cannot be technically unlocked by moving the blades left and right with a tool.

When the key 32 is used for unlocking, the triangular structure 323 at one end of the key rod 322 is inserted into the lock hole 291, so that the right through hole 231 in the first blade 23 and the left through hole 232 of the first blade 23 are pushed away to both sides. At this time, the first notch 233 in the first blade 23 and the second notch 242 in the first blade 23 are moved so as not to be located right above the side pillar, and the bottom edge of the first blade 23 presses the top edge of the side pillar, thereby locking the side pillar. The key 32 is continuously inserted, the curved groove 324 in the key 32 pushes the first protrusion 241 in the second blade 24 to move to the correct position, so that the third notch of the second blade 24 forms a straight groove, and at this time, the second blade 24 is in the unlocked state. The triangular structure 323 of the head 321 of the key 32 connects the second convex column 251 of the third blade 25, or the surface of the third blade 25 is distributed with a right through hole 231 or a left through hole 232. And pushing the third blade 25 to any one of the left side and the right side, wherein the convex second convex column 251 in the third blade 25 is moved away from the upper part of the side column, and at the moment, the third blade 25 is bounced to contact the non-convex bottom edge of the third blade 25 to unlock the side column. When the key 32 is fully inserted into the key cylinder 1, the first blade 23 is urged by the spring into the reset groove 3244 of the key 32. The first blade 23 at this time completes unlocking the lock cylinder 1.

At the same time, the first blade 23 acts as a seal against the locking hole 291 of the lock cylinder 1 by spring return. That is, when the key 32 is completely inserted into the key cylinder 1, the lock hole 291 of the key cylinder 1 is closed by the right through hole 231 and the left through hole 232 of the first blade 23, and the first blade 23, the second blade 24, and the third blade 25 are all in the unlocked state in the state where they cannot be moved. Once the right through hole 231 or the left through hole 232 of the first blade 23 moves, the first blade 23 returns to the locked state. Even if the second blade 24 and the third blade 25 are moved to the correct positions, the key cylinder 1 cannot be opened. Thus, only after the first blade 23, the second blade 24 and the third blade 25 are completely inserted into the key 32, the first notch 233, the second notch 242 and the third notch are connected to form a straight groove, and the second convex column 251 is removed from the upper side of the side column. At this time, the side column is bounced into a linear groove formed by the first blade 23, the second blade 24 and the third blade 25 by the elastic force of at least one third spring. When one part of the side column enters the linear groove from the groove of the shell, the lock liner 2 in the shell can be unlocked and rotated.

According to the requirement, the side column has the function of driving the shifting piece 31 to rotate. The side column enters the linear groove and also enters the groove of the connecting column of the plectrum 31. The shifting piece 31 is connected with the edge of one end of the lock liner 2 in a clamping way through a ring edge with a convex edge. In the process that the lock core 2 is not rotated, one part of the side column is positioned in the groove of the connecting column, and when the polygonal structure of the side column completely falls into the linear groove, the polygonal structure also falls into the groove of the connecting column. The key 32 rotates the cylinder 2 and simultaneously drives the plate 31 to rotate. Since the bottom surface of the end of the cylinder 2 connected to the driver 31 is a sealed surface, the driver 31 cannot be directly contacted from the lock hole 291. The safety performance of the blades of the lock cylinder 1 is ensured.

Specifically, when the bottom edges of the first blade 23 and the third blade 25 are pressed on the convex parts at the two sides of the side column, the second blade 24 cannot contact the concave area in the middle of the side column. In this way, technical unlocking is prevented from being performed at the contact portion between the second groove 212 of the first blade 23 and the side post using a technical unlocking tool. The second blade 24 needs to be adjusted to a correct position to unlock the lock, and it is very difficult to simply shift the second blade 24 to form a straight groove on the second blade 24.

In summary, when the first blade 23 is in the unlocked state, the side column is pressed by the bottom edge of the first blade 23 and cannot be bounced. Thus, the first vane 23 is in a locked state. It is meaningless to toggle the second blade 24 for technical unlocking. When the first blade 23 is in the unlocking state, the lock hole 291 of the lock cylinder 1 is overlapped and shielded by the first blade 23, and if the second blade 24 is shifted left and right to perform technical unlocking, the first blade 23 becomes the locking state. In this way, an interlocking effect is achieved between the first blade 23 and the second blade 24. The third blade 25 is to ensure that the opposite side column is in a balanced state when the first blade 23 is opened, and to prevent one end of the side column from tilting. The first blade 23 and the third blade 25 are also interlocked with each other.

The correct key 32 is inserted into the locking hole 291 of the key cylinder 1, and the first blade 23 is in a locked state during the movement of the key 32. When the key 32 is fully inserted into the key cylinder 1, the key 32 unlocks the first blade 23 and the third blade 25. Meanwhile, the first blade 23 is restored by spring springback and is in an unlocked state. The first blade 23 at this time has a blocking effect on the locking hole 291 of the lock cylinder 1. The lock cylinder 1 is completely in an unlocked state, and the lock cylinder 1 can be opened.

Specifically, the side edges of the second blades 24 are folded edges that overlap each other, and after the connection, the shift piece 31 cannot be contacted by sheets or strips through the gap between the second blades 24. Thereby preventing technical unlocking by a tool reading the blade recess. According to the requirement, the surfaces of the first blade 23 and the third blade 25 are planes, or the surfaces of the first blade 23, the second blade 24 and the third blade 25 are continuously bent by 90 degrees or non-90 degrees, and the side surface is provided with at least one convex-shaped and triangular folded edge.

Specifically, in addition to this, the first blade 23, the second blade 24, and the third blade 25 can be used by being incorporated into the cylinder 2 of the conventional blade lock. The opening shape of the cylinder 2 needs to be matched with the shapes of the first blade 23, the second blade 24, and the third blade 25, as necessary. The side post and the pusher 31 are both configured as a conventional blade lock.

In addition, a partition 27 may be provided between two or more of the first blades 23. The surface of the partition plate 27 is provided with a through hole 28, and the through hole 28 and the lock hole 291 of the lock cylinder 1 have the same size and are positioned on the same axis. The partition 27 partitions the first and second springs to allow independent operation of the springs between the two blades. According to the requirement, the side of the first blade 23 is provided with a convex column or a hook with a right-angle structure for connecting and fixing the first spring and the second spring.

Specifically, in addition, according to the requirement, the third blade 25 comprises at least one set of blades formed by two blades, a left through hole 232 is formed in the surface of one of the blades of the third blade 25, a right through hole 231 is formed in the other blade, and the left through hole 232 and the right through hole 231 are partially distributed and overlapped in a staggered manner at the central line position of the third blade 25. The bottom edge of the third blade 25 is provided with a convex column which protrudes outwards. The center line positions of the left through hole 232 and the right through hole 231 in the two third blades 25 at the lock hole 291 of the lock cylinder 1 are mutually overlapped, a gap with the diameter less than 3mm is reserved at the lock hole 291, and the areas of the non-through holes 28 outside the left through hole 232 or the right through hole 231 in the rest parts of the two third blades 25 are mutually shielded. At this time, the key 32 is continuously inserted into the key cylinder 1, the triangular structure 323 of the head 321 of the key 32 pushes the left through hole 232 and the right through hole 231 in the third blade 25 away to both sides, at this time, the protruding column in the second blade 24 is moved away from above the side column, and at this time, the third blade 25 unlocks the side column.
