As shown in fig. 5, the radial arm assembly includes a radial arm ring 41, a lock tongue 42 and a linkage post 43, wherein the radial arm ring 41 and the lock tongue 42 are both rotationally connected with the housing 11 and the rotation center coincides, the linkage post 43 is rotationally connected with the radial arm ring 41, the lock tongue 42 is fixedly connected with the radial arm ring 41, the axle center of the linkage post 43 is parallel to and not coincident with the rotation axle center of the lock tongue 42, and the rotation rod 52 is rotationally connected with the linkage post 43.
This embodiment has the following advantages:
The key is inserted into the keyhole 26 and is engaged with the lock block 22, and then the key is rotated to engage with the lock block 22 and rotate the lock blade assembly. If the key is matched with the lock cylinder, when the key is in a clamping state with the lock block 22, the key can drive the lock page components to rotate through the lock block 22 and enable the notches 24 of all the lock page components to be positioned 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 lock page components. The lock key is continuously rotated, the lock key drives the lock page assembly to rotate, and the lock bar 51, the rotating rod 52 and the rotating arm assembly are driven to rotate through the lock page assembly, so that the lock can be driven to unlock through the rotating arm assembly.
The unlocking of the lock cylinder requires that all the notches 24 on the lock leaf assemblies are positioned at the lock rod 51 at the same time and the lock rod 51 can enter the notches 24 under the driving of the elastic piece 53, so that any lock leaf assembly can be prevented from entering the notches 24 by the lock leaf assembly with incorrect rotation angle, the lock leaf assembly can not drive the lock rod 51, the rotating rod 52 and the radial arm assembly to rotate, and the lock cylinder is kept in a locked state. In the state that the lock rod 51 is not clamped into the notch 24, the lock page assembly can still rotate freely, so that a cracker can hardly recognize the correct angle of the lock page assembly, and the lock cylinder is hard to crack.
The lock cylinder is normally rotatable even in a state where the lock cylinder is not unlocked, so that whether unlocking is possible cannot be judged by whether the lock cylinder is rotatable or not in the process of breaking the lock cylinder. Most locks in the prior art can be rotated only after being in an unlocking state, so that the lock cylinder has the advantage of being more difficult to crack compared with most locks in the prior art.
Through the joint of internal gear 33 and external gear 34 to make when the lock key drives the holding ring 21 and rotates, the holding ring 21 drives the rotation page 23 through external gear 34 and internal gear 33 and rotates, thereby realizes the lock key and drives the function of lock page subassembly pivoted through locking piece 22 in the rotation process.
The lock core is unlocked through the rotation of the lock leaf component, so that the lock leaf component can be rotated to different angles to form different secret locks (the secret locks are combinations of different lock leaf component rotation angles under the unlocking state, and different angles are formed when the lock leaf component is adjusted to unlock). Because the positioning ring 21 and the rotating page 23 are locked through 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 page components can also influence the locking amount of the lock cylinder. Assuming that the number of teeth of the external gear 34 is x and the number of lock page members is y, the amount of secret locking is the y power of x. For example, the number of teeth of the external gear 34 is 38, the number of lock page components is 4, the secret locking amount reaches the power of 4 (equal to 2085135) of 38, namely, the external gear 34 with the number of teeth of 38 is adopted, and the lock core can be adjusted to 2085135 groups of different secret locking combinations by adopting the 4 lock page components, so that compared with a common spring lock in the market, the lock core has richer secret locking combinations, and therefore, the lock core has better anti-theft effect and is more difficult to crack.
When someone pries the lock, because the notch 24 has a certain depth, when the elastic piece 53 drives the lock rod 51 to be clamped into the notch 24, the lock rod 51 collides with the rotating page 23, so that the vibration and noise of the lock cylinder are easily caused, and the judgment of the successful unlocking of the lock cylinder can be possibly taken as the judgment basis. Through the setting of imitate hole 35 for the lock page subassembly is in the rotation in-process, even do not unblock, and the elastic component 53 drives locking lever 51 card into imitate hole 35 in and collide, thereby imitate the vibration and the noise that send out when locking lever 51 card was gone into breach 24, and then prevent that the people from judging according to locking lever 51 and the vibration and the noise that the collision of rotating page 23 was sent out that locking lever 51 card was gone into breach 24 in, makes this lock core more difficult to be broken.
The outward inclined surface 31 is attached to the inward inclined surface 25, so that the lock lever 51 can be prevented from accidentally slipping out after being locked in the notch 24, and the reliability in unlocking can be improved. When the lock state of the lock cylinder needs to be released, the turning blade 23 is turned in the direction opposite to the turning direction of the turning blade 23 at the time of unlocking, and the turning blade 23 is reversely turned and is abutted against the chamfer 32. Since the width of the chamfer 32 is greater than the depth of the notch 24, the turning page 23 slides relatively to the surface of the lock lever 51 at the chamfer 32 and pushes the lock lever 51 to disengage from the notch 24 along the surface profile of the chamfer 32, thereby changing the unlocked state of the lock cylinder to the locked state.
After the lock rod 51 is locked into the notch 24, the rotating leaf 23 rotates in the rotating process to drive the lock rod 51, the rotating rod 52 and the linkage post 43, the linkage post 43 drives the radial arm ring 41 to rotate, and the linkage post 43 rotates around the rotation center of the radial arm ring 41. Since the axis of the linkage column 43 is parallel to and does not coincide with the rotation axis of the lock tongue 42, and the rotation center of the radial 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 radial arm ring 41, and the rotation speed of the lock tongue 42 is the same as the rotation speed of the radial arm ring 41, so that the lock can be driven to unlock through the lock tongue 42.
Because the rotary arm assembly can directly drive the lock tongue 42 to rotate and unlock when rotating, the rotary interlayer 12 is arranged on one side of the rotary arm assembly close to the lock page assembly, and the rotary arm assembly is blocked by the rotary interlayer 12, so that people can be prevented from directly prying the rotary arm assembly without a key, and the cracking difficulty is improved. The rotary interlayer 12 can play a role of preventing the radial arm assembly from being directly damaged by drilling, and the safety of the lock cylinder is further improved.
The radial arm assembly is blocked by the anti-drilling chassis 13, so that people can be prevented from directly prying the radial arm assembly without using a key, and the cracking difficulty is improved. The anti-drilling chassis 13 can play a role in preventing drilling, so that the radial arm assembly is prevented from being directly damaged by drilling, and the safety of the lock cylinder is further improved. The barrier block 14 also can block the outside drill bit from damaging the radial arm assembly, further improving the security of the lock cylinder. The barrier block 14 can cause barriers to the movement of objects such as wires and pins in the key hole 26, thereby preventing the objects such as wires and pins from prying the lock page assembly and further improving the cracking difficulty.
Example 2:
The blade anti-theft lock cylinder, as shown in fig. 6, differs from embodiment 1 in that: the lock lever 51 is rotatably connected to a flexible roller 54 abutting against the rotary blade 23.
This embodiment has the following advantages:
the lock rod 51 is abutted with the rotating page 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 page 23 is further reduced, and service life is prolonged. Meanwhile, in the collision process of the flexible roller 54 and the rotating page 23, the device has the advantage of small vibration and noise, so that a person is difficult to judge whether the lock rod 51 is clamped into the notch 24 or not through the vibration and the noise, and the difficulty of cracking the lock cylinder is improved.
Example 3:
The blade anti-theft lock core is different from the embodiment 1 in that: the surfaces of the lock rod and the rotating page are provided with flexible coatings.
This embodiment has the following advantages:
The flexible coating on the lock rod and the rotating page are mutually abutted, so that vibration and noise can be reduced, a person is difficult to judge whether the lock rod is clamped into the notch or not through the vibration and the noise, and the cracking difficulty of the lock cylinder is improved.
Example 4:

This embodiment has the following advantages:
During the process of inserting the key into the key hole 26, the outer wall of the unlocking cylinder 61 abuts against the inner wall of the positioning ring 21, and the locking piece 22 is clamped into the through groove 62. Continued movement of 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 lock 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 lock block 22 is rotated until the lock block 22 is clamped with the lock key, so that the lock block 22 and the lock page assembly can be driven to rotate through rotation of the lock key. The unlocking function is realized by setting different lengths of the 4 unlocking grooves 63, and further, different angles of the locking blocks 22 and the locking page components can be simultaneously adjusted in the process of rotating the key.
