After the key is inserted into the key hole 26, the positioning ring 21 and the rotating leaf 23 are driven to rotate by the lock block 22, so that the function of driving the lock leaf assembly to rotate by the lock block 22 in the rotating process of the key is realized.

The locking mechanism comprises an inner gear 33 and an outer gear 34, wherein the outer gear 34 is fixedly connected to the positioning ring 21, and the inner gear 33 is fixedly connected to the rotating page 23 and clamped with the outer gear 34.

The outer edge of the rotary page 23 is provided with a dummy pit 35, the width of the dummy pit 35 is the same as that of the notch 24, and the depth of the dummy pit 35 is smaller than that of the notch 24.

The housing 11 is fixedly connected with a positioning block 16 which is located at the key hole 26 and has the same width as the locking block 22.

As shown in fig. 5, the swing arm assembly includes a swing arm ring 41, a latch 42 and a linking column 43, the swing arm ring 41 and the latch 42 are both rotatably connected to the housing 11 and have their rotation centers coinciding with each other, the linking column 43 is rotatably connected to the swing arm ring 41, the latch 42 is fixedly connected to the swing arm ring 41, the axis of the linking column 43 is parallel to and does not coincide with the axis of rotation of the latch 42, and the swing rod 52 is rotatably connected to the linking column 43.

The embodiment has the following advantages:

the key is inserted into the keyway 26 and engages the key with the lock block 22, and then the key is rotated, which engages the lock block 22 and rotates the leaf assembly. If the key is matched with the lock core, when the key and the lock block 22 are in a clamping state, the key can drive the page locking assemblies to rotate through the lock block 22 and enable the notches 24 of all the page locking assemblies to be located at the lock rod 51, and the elastic piece 53 can drive the lock rod 51 to enter the notches 24 through the rotating rod 52, so that the lock rod 51 is clamped with the page locking assemblies. The key is rotated continuously, the key drives the lock leaf assembly to rotate, and the lock leaf assembly drives the lock rod 51, the rotating rod 52 and the swing arm assembly to rotate, so that the lock can be unlocked by the swing arm assembly.

The unlocking of this lock core needs breach 24 on all the lock page components to be located locking lever 51 simultaneously and can let locking lever 51 get into in breach 24 under the driving of elastic component 53, therefore the rotatory angle of arbitrary lock page component is incorrect, can make this incorrect lock page component of angle block locking lever 51 and get into in breach 24 to make the lock page component can't drive locking lever 51, dwang 52 and spiral arm subassembly and rotate, and then make this lock core keep the lock state. And under the state that the lock rod 51 is not clamped into the notch 24, the page locking assembly can still freely rotate, so that a cracker can hardly recognize the correct angle of the page locking assembly, and the lock cylinder is difficult to crack.

Even if the lock cylinder is not unlocked, the page locking assembly at the key hole 26 can still rotate normally, so that whether unlocking can be carried out cannot be judged through whether the page locking assembly can rotate or not in the process of cracking the lock cylinder. Most of the locksets in the prior art can only rotate after being unlocked, so that the lock cylinder has the advantage of being more difficult to crack compared with most of the locksets in the prior art.

The inner gear 33 is clamped with the outer gear 34, so that when the key drives the positioning ring 21 to rotate, the positioning ring 21 drives the rotating leaf 23 to rotate through the outer gear 34 and the inner gear 33, and the function that the key drives the leaf assembly to rotate through the lock block 22 in the rotating process is realized.

This lock core realizes the unblock through the rotation of lock leaf subassembly, therefore the lock leaf subassembly is rotatory can constitute different picklocks to different angles homoenergetic (the picklock is the combination of different lock leaf subassembly rotation angles under the unblock state, different angles when adjusting the unlock of lock leaf subassembly, forms different picklocks). Because the positioning ring 21 and the rotating page 23 are locked by the external gear 34, the number of teeth of the external gear 34 can directly influence the locking amount of the lock cylinder, and meanwhile, the number of the page locking assemblies also influences the locking amount of the lock cylinder. If the number of teeth of the external gear 34 is x and the number of the lock leaf assemblies is y, the locking amount is the y-th power of x. For example, if the number of teeth of the external gear 34 is 38 and the number of the leaf assemblies is 4, the locking amount reaches 4 th power of 38 (equal to 2085135), that is, if the external gear 34 with the number of teeth of 38 is used and the 4 leaf assemblies are used, 2085135 different locking combinations can be adjusted in the lock cylinder, so that the lock cylinder has richer locking combinations compared with common pin tumbler locks in the market, and therefore has a better anti-theft effect and is more difficult to crack.

When someone picks the lock, because the notch 24 has a certain depth, when the elastic piece 53 drives the lock bar 51 to be clamped into the notch 24, the lock bar 51 collides with the rotating sheet 23, which easily causes vibration and noise of the lock cylinder, and may be used as a judgment basis for successful unlocking of the lock cylinder. Through the setting of imitate hole 35 for the lock page or leaf subassembly is at the rotation in-process, even do not unblock, elastic component 53 orders about locking lever 51 card and goes into and imitate in hole 35 and collide to the vibration and the noise that the imitation locking lever 51 was sent when going into in the breach 24, and then prevent that the people from judging whether locking lever 51 is gone into in breach 24 according to the vibration and the noise that locking lever 51 and rotation page or leaf 23 collision were sent, make this lock core more difficult to be cracked.

The outward-inclined surface 31 is attached to the inward-inclined surface 25, so that the locking rod 51 can be prevented from accidentally sliding out after being clamped into the notch 24, and the reliability in unlocking is improved. When the lock cylinder needs to be unlocked, the turning blade 23 is turned in a direction opposite to the turning direction of the turning blade 23 at the time of unlocking, and the turning blade 23 is turned in the opposite direction and abuts against the chamfer 32. Since the width of the chamfer 32 is larger than the depth of the notch 24, the rotary blade 23 slides relative to the surface of the lock bar 51 at the chamfer 32 and pushes the lock bar 51 to be separated from the notch 24 along the surface profile of the chamfer 32, so that the unlocking state of the lock cylinder is changed into the locking state.

After the lock rod 51 is locked in the notch 24, the rotating leaf 23 drives the lock rod 51, the rotating rod 52 and the linkage column 43 to rotate in the rotating process, the linkage column 43 drives the rotating arm ring 41 to rotate, and the linkage column 43 rotates around the rotating center of the rotating arm ring 41. Because the axle center of the linkage column 43 is parallel to and does not coincide with the rotation axle center of the lock tongue 42, and the rotation center of the rotary arm ring 41 coincides with the rotation center of the lock tongue 42, the linkage column 43 drives the lock tongue 42 to rotate in the process of rotating around the rotation center of the rotary arm ring 41, the rotation speed of the lock tongue 42 is the same as that of the rotary arm ring 41, and therefore the lock can be unlocked by driving the lock tongue 42.

Because rotate the spiral arm subassembly and can directly drive spring bolt 42 when rotating and rotate and realize the unblock, consequently set up rotatory intermediate layer 12 in one side that the spiral arm subassembly is close to the page or leaf subassembly, keep off the spiral arm subassembly through rotatory intermediate layer 12, can prevent that the people from directly prizing the spiral arm subassembly without the key to play and improve and explain the degree of difficulty. The rotary interlayer 12 can play a role of drilling prevention, the radial arm assembly is prevented from being damaged by drilling directly, and the safety of the lock cylinder is further improved.

The spiral arm assembly is blocked by the anti-drilling base plate 13, so that a person can be prevented from directly prying the spiral arm assembly without a key, and the cracking difficulty is improved. The drilling-proof chassis 13 can play a role of drilling-proof, prevent the radial arm component from being damaged by drilling directly, and further improve the safety of the lock cylinder. The barrier block 14 also prevents an external drill bit from drilling out the radial arm assembly, further improving the security of the lock cylinder. The barrier block 14 can block the movement of objects such as iron wires and needles in the key hole 26, so that the objects such as the iron wires and the needles are prevented from prying the page locking assembly, and the cracking difficulty is further improved.

Example 2:

the anti-theft lock core of the leaf, as shown in fig. 6, is different from embodiment 1 in that: a flexible roller 54 abutting against the rotary blade 23 is rotatably connected to the lock lever 51.

The embodiment has the following advantages:

the lock rod 51 is abutted against the rotating sheet 23 through the flexible roller 54, sliding friction is converted into rolling friction, friction force can be reduced, abrasion of the lock rod 51 and the rotating sheet 23 is reduced, and service life is prolonged. Meanwhile, the flexible roller 54 has the advantages of small vibration and noise in the process of colliding with the rotating page 23, so that people can hardly judge whether the lock rod 51 is clamped into the notch 24 through vibration and noise, and the unlocking difficulty of the lock cylinder is improved.

Example 3:

the anti-theft lock core of the leaf, it is different from embodiment 1 in: the surfaces of the lock rod and the rotating blade are both provided with flexible coatings.

The embodiment has the following advantages:

through the mutual butt of flexible coating on locking lever and the rotation page or leaf, can reduce vibrations and noise, make the people be difficult to judge whether the locking lever card goes into in the breach through vibrations and noise, play the degree of difficulty that explains that improves this lock core.

Example 4:

the anti-theft lock assembly of the leaf, as shown in fig. 7 and 8, includes the lock key and the anti-theft lock core of the leaf in embodiment 1, the lock key includes the cylinder of unblock 61, the cylinder of unblock 61 has through slot 62 and unblock slot 63, unblock slot 63 sets up 4 totally, through slot 62 extends and link up to one end of cylinder of unblock 61 along the length direction of cylinder of unblock 61, unblock slot 63 extends and one end communicates with through slot 62 along the circumference of cylinder of unblock 61, the width of through slot 62 equals the length of lock block 22, the width of unblock slot 63 equals the width of lock block 22.

The embodiment has the following advantages:

during insertion of the key into the keyway 26, the outer wall of the unlocking cylinder 61 abuts the inner wall of the retaining ring 21 and the locking piece 22 snaps into the through groove 62. Continuing to move the key, the lock block 22 moves relative to the key and adjusts position within the through slot 62. After the position of the lock block 22 is adjusted, the key is rotated to enable the lock block 22 to be clamped into the unlocking groove 63 extending along the circumferential direction of the unlocking cylinder 61, and the rotation is continued until the lock block 22 is clamped with the key, so that the lock block 22 and the lock leaf assembly can be driven to rotate through the rotation of the key. The 4 unlocking grooves 63 are set to have different lengths, so that different lock blocks 22 and different lock page assemblies can be adjusted to rotate by different angles in the process of rotating the key, and the unlocking function is realized.

In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
