After the lock key is inserted into the key hole 26, the lock block 22 drives the positioning ring 21 and the rotating leaf 23 to rotate, thereby realizing the function that the lock key drives the lock leaf assembly to rotate through the lock block 22 during the rotation process.

The locking mechanism includes an internal gear 33 and an external gear 34 , the external gear 34 is fixedly connected to the positioning ring 21 , and the internal gear 33 is fixedly connected to the rotating leaf 23 and clamped with the external gear 34 .

The outer edge of the turning page 23 is provided with an imitation pit 35 , the width of the imitation pit 35 is the same as the width of the notch 24 , and the depth of the imitation pit 35 is smaller than the depth of the notch 24 .

The turning leaf 23 is provided with inwardly inclined surfaces 25 located on both sides of the notch 24. The end of the inwardly inclined surface 25 away from the bottom of the notch 24 is inclined toward the inner side of the notch 24. One side of the lock bar 51 is provided with a cambered surface that fits the inwardly inclined surface 25. The other side of the surface 31 and the locking bar 51 is provided with a chamfer 32 , the width of the chamfer 32 is greater than the depth of the notch 24 .

The swivel arm assembly is rotatably connected with a swivel interlayer 12, and the swivel interlayer 12 is located on the side of the swivel arm assembly close to the lock leaf assembly.

An anti-drilling chassis 13 is arranged between the rotating interlayer 12 and the lock leaf assembly, and the two ends of the anti-drilling chassis 13 are respectively connected in rotation with the rotating interlayer 12 and the positioning ring 21, and the anti-drilling chassis 13 is fixedly connected with an obstacle block 14 located in the keyhole 26 , A movable chamber 15 is provided between the barrier block 14 and the locking leaf assembly.

As shown in Figure 5, the swing arm assembly includes a swing arm ring 41, a deadbolt 42 and a linkage post 43, the swing arm ring 41 and the lock tongue 42 are both rotatably connected to the housing 11 and the center of rotation coincides with each other, and the linkage post 43 is rotatably connected to the swing arm The arm ring 41 and the lock tongue 42 are fixedly connected with the swing arm ring 41 , the axis of the linkage column 43 is parallel to the rotation axis of the lock tongue 42 and does not overlap, and the rotation rod 52 is rotatably connected to the linkage column 43 .

This embodiment has the following advantages:

Insert the key into the key hole 26, and make the key engage with the lock block 22, then turn the key, the key engages with the lock block 22 and drives the lock leaf assembly to rotate. If the key fits the lock cylinder, when the key and the lock block 22 are engaged, the key can drive the lock leaf assembly to rotate through the lock block 22 and make all the notches 24 of the lock leaf assembly located at the lock bar 51, and elastically The member 53 can drive the lock bar 51 into the notch 24 through the rotating bar 52, so that the lock bar 51 is engaged with the lock leaf assembly. Continue to turn the key, the key drives the lock leaf assembly to rotate, and drives the lock bar 51, the rotating bar 52 and the swing arm assembly to rotate through the lock leaf assembly, so that the lock can be unlocked by the swing arm assembly.

The unlocking of the lock core requires that the notches 24 on all the lock leaf assemblies be located at the lock bar 51 at the same time and allow the lock bar 51 to enter the notch 24 under the drive of the elastic member 53, so that any one lock leaf assembly rotates at an incorrect angle. That is to say, the locking leaf assembly with an incorrect angle blocks the locking rod 51 from entering the notch 24, so that the locking leaf assembly cannot drive the locking rod 51, the rotating rod 52 and the swing arm assembly to rotate, thereby keeping the lock cylinder in a locked state. And in the state that the locking bar 51 is not snapped into the gap 24, the lock leaf assembly can still rotate freely, making it difficult for crackers to identify the correct angle of the lock leaf assembly, making the lock cylinder difficult to be cracked.

Even if the lock core is not unlocked, the lock leaf assembly at the keyhole 26 can still rotate normally, so that whether it can be unlocked can not be judged by whether the lock leaf assembly can rotate in the process of cracking the lock core. However, most of the locksets in the prior art can only be rotated after being in the unlocked state, so that the lock cylinder has the advantage that it is more difficult to be cracked than most of the locksets in the prior art.

The internal gear 33 is engaged with the external 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 external gear 34 and the internal gear 33, thereby realizing that the key passes through the lock block 22 during rotation. The function of driving the lock leaf assembly to rotate.

The lock cylinder is unlocked by the rotation of the lock leaf assembly, so the lock leaf assembly can be rotated to different angles to form different secret locks (the secret lock is a combination of different lock leaf assembly rotation angles in the unlocked state, adjust the lock leaf assembly when unlocking) Different angles form different secret locks). Because the locking is realized by the external gear 34 between the positioning ring 21 and the rotating leaf 23, the number of teeth of the external gear 34 can directly affect the sealing capacity of the lock cylinder, and at the same time, the number of locking leaf components will also affect the security of the lock cylinder lock amount. Assume that the number of teeth of the external gear 34 is x, and the number of locking leaf assemblies is y, then the secret locking amount is x to the yth power. For example, if the number of teeth of the external gear 34 is set to 38, and the number of lock leaf assemblies is set to 4, then the secret lock amount reaches the 4th power of 38 (equal to 2085135), that is, the external gear 34 with 38 teeth is adopted, and 4 If there are two lock leaf components, the lock cylinder can adjust 2085135 different combinations of secret locks, which makes the lock cylinder have more abundant combination of secret locks than the common tumbler locks on the market, so it also has better anti-theft effect. more difficult to crack.

When someone picks the lock, since the notch 24 has a certain depth, when the elastic member 53 drives the lock bar 51 to snap into the notch 24, the lock bar 51 collides with the rotating leaf 23, which will easily cause vibration and noise of the lock cylinder, possibly It will be used as the basis for judging the successful unlocking of the lock cylinder. By imitating the setting of the pit 35, during the rotation of the locking leaf assembly, even if it is not unlocked, the elastic member 53 drives the locking bar 51 into the imitating pit 35 and collides, thereby imitating the sound issued when the locking bar 51 snaps into the notch 24 Vibration and noise, and then prevent people from judging whether the lock bar 51 is stuck in the gap 24 according to the vibration and noise that the lock bar 51 collides with the rotating leaf 23, so that the lock cylinder is more difficult to be cracked.

The outer inclined surface 31 is attached to the inner inclined surface 25, which can prevent the locking rod 51 from accidentally slipping out after being stuck in the notch 24, thereby improving the reliability of unlocking. When the locked state of the lock cylinder needs to be released, the rotating leaf 23 is rotated in the direction opposite to the rotating direction of the rotating leaf 23 during unlocking, and the rotating leaf 23 rotates in the opposite direction and abuts against the chamfer 32 . Because the width of the chamfer 32 is greater than the depth of the notch 24, the rotating leaf 23 slides relative to the surface of the lock bar 51 at the chamfer 32 and pushes the lock bar 51 away from the notch 24 along the surface contour of the chamfer 32, thereby unlocking the lock cylinder status changes to locked status.

After the locking rod 51 is snapped into the gap 24, the rotating leaf 23 drives the locking rod 51, the rotating rod 52 and the linkage column 43 to rotate during the rotation process, and the linkage column 43 drives the swing arm ring 41 to rotate, and the linkage column 43 rotates around the swing arm ring 41 The center of rotation rotates. Since the axis of the linkage column 43 is parallel to and does not coincide with the axis of rotation of the dead bolt 42, and the rotation center of the swing arm ring 41 coincides with the rotation center of the lock tongue 42, the linkage column 43 is at the center of rotation around the swing arm ring 41. During the rotation, the dead bolt 42 is driven to rotate, and the rotating speed of the dead bolt 42 is the same as that of the swing arm ring 41, so that the lock bolt 42 can drive the lock to be unlocked.

Because the swivel arm assembly can directly drive the dead bolt 42 to rotate and realize unlocking when the swivel arm assembly rotates, a swivel interlayer 12 is set on the side of the swivel arm assembly near the lock leaf assembly, and the swivel arm assembly is blocked by the swivel interlayer 12, which can prevent people from directly locking the lock without using a key. Pry the arm assembly to increase the difficulty of cracking. The rotating interlayer 12 can play the role of anti-drilling, prevent the swing arm assembly from being directly damaged by drilling, and further improve the safety of the lock cylinder.

Blocking the swing arm assembly by the anti-drilling chassis 13 can prevent people from directly prying the swing arm assembly without a key, thereby increasing the difficulty of cracking. The anti-drilling chassis 13 can play the role of anti-drilling, prevent the swing arm assembly from being directly drilled, and further improve the safety of the lock cylinder. The obstacle block 14 can also stop the external drill bit from damaging the swing arm assembly, further improving the safety of the lock cylinder. The obstacle block 14 can cause obstacles to the activities of objects such as iron wires and needles in the keyhole 26, thereby preventing objects such as iron wires and needles from prying the lock leaf assembly, further improving the difficulty of cracking.

Example 2:

The leaf anti-theft lock cylinder, as shown in FIG. 6 , is different from Embodiment 1 in that: the locking bar 51 is rotatably connected with a flexible roller 54 abutting against the rotating leaf 23 .

This embodiment has the following advantages:

The locking bar 51 is in contact with the rotating leaf 23 through the flexible roller 54, and the sliding friction is converted into rolling friction, which can reduce the friction force, thereby reducing the wear of the locking bar 51 and the rotating leaf 23, and improving the service life. Simultaneously, in the process that the flexible roller 54 collides with the rotating leaf 23, it has the advantage of less vibration and noise, which makes it difficult for people to judge whether the lock bar 51 is stuck in the gap 24 through the vibration and noise, so as to improve the cracking of the lock cylinder. difficulty.

Example 3:

The difference between the leaf anti-theft lock cylinder and the first embodiment is that the locking rod and the surface of the rotating leaf are all provided with a flexible coating.

This embodiment has the following advantages:

The contact between the lock rod and the flexible coating on the rotating page can reduce vibration and noise, making it difficult for people to judge whether the lock rod is stuck in the gap through vibration and noise, thereby increasing the difficulty of cracking the lock cylinder.

Example 4:

The leaf anti-theft lock assembly, as shown in Figure 7 and Figure 8, includes a key and the leaf anti-theft lock cylinder in Embodiment 1, the key includes an unlocking cylinder 61, and the unlocking cylinder 61 is provided with a through groove 62 and an unlocking groove 63 There are 4 unlocking grooves 63 in total. The through groove 62 extends along the length direction of the unlocking cylinder 61 and penetrates to one end of the unlocking cylinder 61. The unlocking groove 63 extends along the circumference of the unlocking cylinder 61 and communicates with the through groove 62 at one end. , the width of the through slot 62 is equal to the length of the lock block 22 , and the width of the unlocking slot 63 is equal to the width of the lock block 22 .

This embodiment has the following advantages:

During the process of inserting the key into the keyhole 26 , the outer wall of the unlocking cylinder 61 abuts against the inner wall of the positioning ring 21 , and the lock block 22 snaps into the through groove 62 . As the key continues to be moved, the lock block 22 moves relative to the key and adjusts its position in the through slot 62 . When the position of the lock block 22 is adjusted, turn the key so that the lock block 22 snaps into the unlocking groove 63 extending in the circumferential direction of the unlocking cylinder 61, and continue to rotate until the lock block 22 is engaged with the key, so that the lock block 22 can be locked by the rotation of the key. Drive the lock block 22 and the lock leaf assembly to rotate. By setting the four unlocking slots 63 with different lengths, different lock blocks 22 and lock leaf assemblies can be adjusted to rotate at different angles during the process of turning the key to realize the unlocking function.

To sum up, after reading the document of the present invention, those of ordinary skill in the art can make various other corresponding conversion schemes according to the technical solutions and technical concepts of the present invention without creative mental work, all of which fall within the protection scope of the present invention.
