Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an encodable code matching mechanism. Background Art

[0002] The rotary combination lock has the following advantages: 1. No keys, power supply or batteries are needed, and there is no waste pollutant; 2. The fully mechanical structure can withstand a very harsh external environment and has a wide range of uses; 3. The actual password is large and the confidentiality performance is high, and the probability of trial unlocking is almost zero; 4. The structure is simple, strong and reliable. Therefore, the rotary combination lock is widely used in various safes. Traditional rotary combination locks have several disadvantages:

[0003] 1. The operation is cumbersome. Since the external operating knob is only connected to one internal active disk, the other internal follower disks cannot be turned directly by the knob, but must be rotated indirectly by the contact of the tongues of the active disk and the follower disk. The first active disk must rotate one circle clockwise to drive the second follower disk to rotate. The first active disk continues to rotate one circle clockwise, and the second follower disk also rotates one circle, thereby driving the third follower disk. The first active disk continues to rotate to drive the third follower disk to the position where it can be unlocked (the first password); rotating an active disk in the opposite direction requires one circle to drive the second follower disk to rotate in the opposite direction, and then rotating the first active disk again, the second follower disk also rotates in the opposite direction to the position where it can be unlocked (the second password); the first active disk is moved forward again to the position where it can be unlocked (the third password); so the knob must be repeatedly rotated clockwise and reversed for several circles to turn the several disks to the predetermined position;

[0004] 2. It is not easy to input the password. The password is distinguished by the precise scale on the edge of the knob. The accuracy of the password can be judged by turning the knob at a small angle. If you are not careful, you may enter the wrong password. Moreover, the password can only be entered in one direction. If the number is exceeded, the rotation is invalid and you can only start over.

[0005] 3. The number of passwords is small. Take a three-piece high-end disc-type mechanical password lock as an example. Assuming that the knob has 100 scale values, the three-piece combination nominally has 100 cubed, which is 1 million passwords, but in fact it is not possible at all. Because when using the knob to match the password, it is very difficult to distinguish a scale (3.6 degrees) by turning the hand alone, and coupled with the influence of mechanical processing errors, it is impossible to accurately match the code according to a scale value. In order to ensure the success rate of entering the password, sufficient margin must be left in the structure. Therefore, the traditional disc-type mechanical password lock allows a ±1.5 scale difference when matching the code, that is, every 3 scales are a valid value. No matter how precise the scale on the edge of the knob is, there are only 100 scales. Even if there are 50 valid scale values, the three-piece type can only have 503=125,000 passwords. It is far less than the nominal number of passwords. If a four-piece type is used to increase the number of passwords, the operation will be extremely cumbersome. Many operations such as turning left four times for the first password, turning right three times for the second password, and turning left two times for the third password are very difficult to learn.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] For example, see Figure 1-12The utility model discloses an encodable code matching mechanism, including a lock core 1 and a code disk body 2, the lock core 1 includes an inner dial shaft 11 and an outer dial shaft 12, the inner dial shaft 11 is provided with a plurality of equally spaced driving grooves 13 along its axial direction, the inner dial shaft 11 is sleeved with a plurality of equally spaced blades 14 corresponding to the driving grooves 13 along its axial direction, the blades 14 are provided with protrusions 141, a driving hole is provided inside the blades 14, and a straight edge 142 corresponding to the protrusions 141 is provided inside the driving hole, the Springs 15 are provided on both sides of the blade 14, the inner shaft 11 is movably sleeved inside the outer shaft 12, and the outer shaft 12 is provided with grooves that are sleeved with the blade 14 and the springs 15 on both sides thereof.

[0048] For example 2, please refer to Figure 1-14Compared with the above embodiment, the present embodiment further includes an extended inner dial shaft 4, an extended outer dial shaft 12, a key groove 6 and a card groove 7. The boss 16 and the password number disk 18 at one end of the outer dial shaft 12 in the above embodiment are moved to one end of the extended outer dial shaft 12, and a card groove 7 is arranged inside one end of the outer dial shaft 12. The shift block 111 at one end of the inner dial shaft 11 in the above embodiment is moved to one end of the extended inner dial shaft 4, and a key groove 6 is arranged at one end of the inner dial shaft 11. One end of the extended inner dial shaft 4 is movably inserted into the interior of the key groove 6, and one end of the extended inner dial shaft 4 is provided with a card position matching the key groove 6, so that when the extended inner dial shaft 4 rotates, the inner dial shaft 11 is driven to rotate synchronously, and one end of the extended outer dial shaft 12 is movably inserted into the interior of the card groove 7. One end of the extended outer dial shaft 12 is provided with a card position matching the card groove 7, so that when the extended outer dial shaft 12 rotates, the outer dial is driven to slide and rotate synchronously.
