[Technical field to which the invention belongs] The present invention relates to a cylinder lock, and more particularly to a cylinder lock whose password can be changed. [Prior art] There is a known so-called disposable-loss variable-lock cylinder lock that can only change the number of times the key is changed in advance. This kind of circle :: lock has: the outer cylinder 1; the inner cylinder 2; the inner cylinder side sliding hole 3] which is inserted through the inner cylinder; and the inner cylinder side sliding hole 3 is housed ... horse pin 32, and a variable pin 33 that abuts on this cipher pin 32 from the outer cylinder 1 side to extend the length of the Mimar pin 32. It also has an outer cylinder side / moon moving hole 34 which is inserted in the outer cylinder and can communicate with the inner cylinder side sliding hole 31 when the dense = pin 32 is at the reference position, and is accommodated in the outer cylinder side sliding hole 34, and The driving pin 3 6 is pressed by the elastic element ^ toward the inner cylinder 1 side. It also has a pin-receiving hole 6 which is provided in the inner cylinder 2 and is opened to the outer cylinder-side sliding hole 34 when the inner cylinder 2 is rotated by a predetermined angle. Since this structure has multiple segments, it is possible to change the password multiple times. Next, the operation of the cylinder lock will be described. The general operation is performed by rotating the general key NK clockwise with the general key NK inserted in the key hole 2a as shown in Figs. 13 (b)) to (b-3). At this time, since the variable pin 33 is often accommodated in the inner cylinder side sliding hole M, and the abutting surface of the variable pin 33 and the transmissions 6 is often located on the outer peripheral surface of the inner cylinder 2, the inner cylinder 2 can be positioned at the 13th position. (B_2) to (b_3) in the figure. 314641 5 1227299 As shown in Fig. 13 (1) to (C-3), the password is changed by using the change key ck instead of the general key Nκ. That is, when the cipher pin 32 is located at the reference position, the change key ck is inserted into the key hole 2a, whereby the variable pin 33 is housed in the outer cylinder-side slide hole 34 against the spring pin of the transmission pin 36, and the variable is formed. The state where the contact surface of the pin 33 and the pin 32 is located on the outer peripheral surface of the inner cylinder 2 (refer to FIG. 13 (c-1)). Next, in the state where the change key CK is inserted, that is, the variable pin 33 is accommodated in the outer cylinder-side slide hole 34, until the variable pin accommodation hole 6 reaches the reference position (refer to the first (C-2)). Thereby, the variable pin 33 accommodated in the outer cylinder-side slide hole 34 is accommodated in the variable pin accommodation hole 6 in accordance with the elasticity of the transmission pin 36. Next, in a state in which the change key CK is inserted, that is, the variable pin 33 is accommodated in the accommodation hole 6, until the inner cylinder-side slide hole 31 reaches the reference position (refer to FIG. 13 ... "))). As described above, removing the woven pin 33 that abuts on the password pin 32 to extend the length of the password pin 32 can shorten the appearance length of the password pin 32, and The password of the cylinder lock can be changed to a new password by the management personnel. This makes it impossible to recover the lost key, and at the same time makes the new material effective. Moreover, the above cylinder lock is used when the administrator assigns maintenance work to the operator. Down is still valid. This is because the office in a certain field of work is transferred from the work MA to the workman, and the recording key used has been used, and it can be quickly entered without the need to exchange cylinder locks.> 314641 6 1227299 The spoon produces a useful treatment. However, because the cylinder lock can be changed a limited number of times, once the number of changes is used, it is not possible to change the Mimar afterwards, but only by replacing the cylinder lock.

Only new passwords can be used. 'Even for 8-segment variable locks, when A ϋ is used as a cycle to form the exchange sequence, all cylinder locks must be replaced when entering the fourth cycle. There are more than 8 paragraphs. Moreover, the loss of keys does not happen several times in a short period of time. If so, in the case of using a variable lock at each stage of the year, all 8 segments are used, and it will take at least 8 years. After such a long period of time, the possibility of the entry of the lost recording key will be extremely small. At this point, it should be possible to restore the encryption code that was used 8 years ago, but the cylinder lock in the past could not do this. Furthermore, even if the key is temporarily lost due to misunderstanding of the user, once the password is changed, it cannot be restored to the original password, so it will cause a waste of limited use of the double post code, and the life of the cylinder lock. Shortening 0 [Summary of the Invention] The author of this article, Moyuki Nakamura, aims to provide a variable lock cylinder lock that can change the password permanently and repeatedly. The other purpose of the present invention is to provide 7 3) 4641 1227299 passwords that can be changed quickly and securely in addition to the above purpose.

The structure and function of the two types of keys (change key and general key) used for the above cylinder locks and the rotation restricting mechanism with respect to the remaining keys are described below. (The structure of the “Transfer 4”. The structure of the general recording key) The key for change is the key used when changing the password of the cylinder lock. There are eight types from CK1 to CK8. If the change keys cK1 and CK2 among these are described, as shown in FIG. 3 (a), the key plates cKla and 2a are formed with notch portions CKlb and 2b for rotation restriction, respectively, and act on the variable password generation unit. The variable cryptographic sections CKlc and 2c of 3; and a unique cryptographic section (not shown) that acts on the unique password generating section 4. In addition, the change keys shown in the figure are only CK1 and CK2, but the other change keys (CK3 to 8) 'differ in the configuration of the variable password section (CK3c to 8c), and the notch section (CK3b to 8b) The formation position and the structure of the unique encryption unit are common to each other. General recording keys are used for general opening and closing operations. There are eight types of NK1 to NK8. —General keys NK1 and nK2 are as shown in Fig. 3 (b). 'The rest of the mouth part with the above-mentioned change recording keys CK1 and CK2 have the icon for the change, but the formation of other general keys NKlb, 2b. Except for different positions, the rest of the keys are roughly the same. Moreover, although not shown (NK3 to 8), they have the same configuration.

On the other hand, the 'restriction pin' of the rotation-restricted son-in-law is formed as shown in Fig. 4 (c) and (a). Set the clockwise direction to the universal key Nκ, and it will not be subject to the rotation restriction when the key is turned on. LtThe mattress can be turned clockwise to perform the rotation operation. Extend without turning (refer to Figure 5 (b)). Another +] I good system and the other-in the counterclockwise direction, the keys CK1 to 8 are used for the Korean gate. When the rotation is delayed, the rotation is not restricted by the pin 5b, but it can be turned toward t The system will be restricted by the rotation restriction pin 5 & when the m-order rotation is known, '...' is restricted without rotation (see Fig. 5 (a)). In the same figure as in Fig. 4 ", there are two rotation restriction grooves 2b and 2c. The rotation restriction grooves are formed at positions corresponding to the above-mentioned pin 5a. Decide on the rotation range of NK from the limit of the special movement. On the one hand, the rotation limit groove 2c is different from the one on the other side. &Amp; The other monks and 疋 are formed at the position corresponding to the rotation limit, and the change path ef_ π ' J pin 5b uses the rotation range of key CK and the range up to Y. 'To the code is as described above' By setting the rotation control on the outer cylinder i and the rotation control on the inner cylinder 2 2c, a 5b, and key CK for password change Wide change position ..., code change position ¥ range, and can be in the base: This rotation range does not precess with the use of a general key: direction, so that the rotation range of 2 is repeated Therefore, it can be correct and correct: the operation of changing the inner cylinder density of ¥ and ¥ can also ensure safety. Λ quickly grasps the following description of the cylinder lock structure described above In addition, the following said 314641 12 1227299 The password conversion of the password numbers # i and # ~ and # 2 will be described. The password conversion of other combinations of password numbers (such as Μ β 4. jin ', and # 8, # 5, and # 6 寺) is also the same as the following. Moreover, u 土, 土 本 一 疋 for all keys The unique cryptographic sections are all in a normal state, and the rotation of the inner cymbal 2 caused by the unique cryptographic generating section 4 will be explained below. If the unique cryptographic section is abnormal, the rotation restriction is It will work, and the inner ring 2 will not be able to rotate due to the restriction of the transmission pin 45 inherent in the code generating unit 4. (Forward password change) When changing the password for forward direction (## 2), the fifth paragraph The role of the variable password generation unit 3 will be described. When the inner cylinder 2 is in a normal state, that is, the password pin 32 is located at the reference position X 蚪 (see FIG. 6 (a) and FIG. 10 (a)), The change key CK1 is inserted into the key hole 2a (refer to FIG. 6 (b) and FIG. 10 (b)). At this time, the variable pin 3 3g is housed on the inner cylinder side and slides along the spring pin of the transmission pin 36. In the state of the hole 3 1, the abutting surface of the variable pin 33 and the cipher pin 32 is formed on the outer peripheral surface of the inner cylinder 2. State, so the inner cylinder 2 can be turned counterclockwise. Next, when the change key C K1 is inserted into the remaining key hole 2 a, it is turned counterclockwise 45. The pin 32 is moved to the password change position. Y 'and communicate the inner cylinder side slide hole 3 1 with the outer cylinder side slide hole 3 7 (tea ft ?, Fig. 6 (c)). At this time, the variable pin 33 is accommodated in the inner cylinder side slide hole 3 In the state of 1, it is moved to the password change position γ, and the password change position Υ is in contact with the transmission lock 39. Next, after the change key CK1 孓 is pulled out from the keyhole 2a (refer to FIG. 7 (a )) 'Insert the key cK2 for change into the keyhole 2a of the wheel (refer to Section 7 13 31464] 1227299 back ^)) On this day, the variable pin 3 3 will be formed to resist the spring pressure of the transmission pin 3 9. The side sliding hole 37 is in a state where the contact surface of the variable pin 3 3 and the dense and some abutment surface comes to the outer peripheral surface of the inner tube 2, so the inner tube 2 can be rotated clockwise. Next, with the change key CK2 inserted into the key hole 2a, it is turned 45 clockwise. Then, the cipher pin 32 is moved to the reference position, and the inner cylinder-side sliding hole 31 is communicated with the outer cylinder-side sliding hole 34 (see FIG. 7 (c) and FIG. 7 (c)). At this time, the variable pin 33 is still accommodated in the outer cylinder moon moving hole 3 7 ', thereby completing the password change in the forward direction (# 1-># 2) (refer to FIG. 8 (a) and FIG. 11 (a )). The following is a description of the normal function of the code generation unit 3 after the above-mentioned forward password change (password number # 2), the fifth I can be delivered to the code generation unit 3. In the state where the key is pulled out, all the transmission pins 36 are located on the outer peripheral surface of the inner cylinder 2, so the inner cylinder 2 does not rotate (refer to FIG. 8 (a) and iJ (a)). The key NK1 is inserted into the key hole 2a, and the transmission pin 36 of the fifth stage is still located on the outer peripheral surface of the inner cylinder 2, so the inner cylinder 2 does not rotate (see FIG. 11 (b)). In contrast, when the general key NK2 is inserted into the key hole 2a, the contact surface of the transmission pin 36 and the cipher pin 32 of the fifth stage is located on the outer peripheral surface of the inner cylinder 2 (refer to FIG. 8 (b) and 11). Figure (c)). Therefore, the rotation operation of the inner cylinder 2 can be performed in a state where the general recording key NK2 is inserted into the key hole 2a, and the inner cylinder 2 can be performed in a clockwise direction by 45. The predetermined opening and closing mechanism is activated by the turning operation (see Fig. 8 (c)). (Reverse password change) 31464] 1227299 The following describes the role of the fifth-stage variable password generating unit 3 when the password change is reversed (# 2— # 1). When the inner cylinder 2 is in the normal state, that is, when the password pin 32 is at the reference position X (refer to FIG. 8 (a)), insert the change key CK2 into the key hole 2a (see FIG. 7 (c)) ^ At this time, a state in which the contact surface of the combination lock 32 and the transmission pin 36 comes to the outer peripheral surface of the inner cylinder 2 is formed, so the inner cylinder 2 can be rotated counterclockwise. Next, turn the recording key CK2 for change into the keyhole 2a, and turn it counterclockwise 4 5. , The password pin 3 2 is moved to the password change position Y ′, and the inner cylinder side slide hole 31 is communicated with the outer cylinder side slide hole 3 7 (see FIG. 7 (b)). At this time, the variable pin 33 is accommodated in the outer cylinder-side slide hole 37. Next, after removing the change key CK2 from the key hole 2a (refer to FIG. 7 (a)), insert the change key CK1 into the key hole 2a (refer to FIG. 6 (0).) At this time, the variable pin 33 will be smoothly inserted. A state in which the transmission pin 39 is accommodated in the inner cylinder-side sliding hole 31 is formed by the elasticity of the transmission pin 39, and a contact surface between the variable pin 33 and the cipher pin 32 is brought to the outer peripheral surface of the inner cylinder 2. Next ' With the change key CK1 inserted into the key hole 2a, turn it clockwise 45. Move the PIN 32 to the reference position X and connect the inner same-side slide hole 3 1 to the outer cylinder-side slide hole 3 4 (see (6) (b)). At this time, the variable pin 33 is moved to the reference position X while being accommodated in the slide hole 3 j on the inner cylinder side, and is formed at the reference position χ to abut the transmission pin 36. State, to complete the password change in reverse # 丨) (refer to Figure 6 (a) and Figure 12 (a)). In addition, the above-mentioned series of functions are related to the functions of the fifth paragraph of the variable password generation 314641! 227299 Part 3, but in parallel with these, the fourth paragraph of the variable password generation section 3 also performs the same change as the above-mentioned forward password change. Acceptance of Pin 3 3. On the other hand, as long as the variable code generating unit 3 of the first to third stages is about the above-mentioned fork code conversion (# 1 — # 2 or # 2 — # 1), the variable pin 33 is not granted. & The following is a description of the general role of the 4th to 5th stage variable password generation unit 3 after the reverse password change (password number # 丨). In the state where the key is pulled out, all the transmission pins 36 are located on the outer peripheral surface of the inner cylinder 2, so the inner cylinder 2 does not rotate (refer to Figs. 9 (a) and 12 (a)). NK2 is inserted into the keyhole 2a, and the driving pin 36 of the fourth stage is still located on the outer peripheral surface of the inner cylinder 2, so the inner cylinder 2 does not rotate (see Fig. 12 (b)). In contrast, when the general key NK1 is inserted into the key hole 2a, the abutting surface of the driving pin 36 and the cipher pin 32 of the fourth stage is located on the outer peripheral surface of the inner cylinder 2, and the driving pin 36 of the fifth stage and the variable The contact surface of the pin 33 is also positioned on the outer peripheral surface of the inner tube 2 (see FIG. 9 (b) and FIG. 12 (c)). Therefore, when the general key NK1 is inserted into the remaining keyhole 2a, the inner 2 can be rotated, and the inner cylinder 2 can be clockwise 4 $. The turning operation is performed by a predetermined opening and closing mechanism (see FIG. 9 (c)). (Others) In the above embodiment, the 5-segment variable cipher generation unit 3 and the 4-segment i code generation unit 4 are provided, but the present invention is not limited to this. For example, the variable-density T generation unit 3 and the unique cipher generation unit 4 may be used. The numbers are each doubled, or the number of these decreases. In addition, there may be two or more lines of variable 314641] 6 1227299 Mountain code generating unit 3 and a variable password generating unit 3, a unique password generating unit 4, or only a variable with the [invention effect] The reversible variable pin two-cylinder lock has the above-mentioned structure, so the cylinder lock can only have pp ... so it is not like the conventional variable lock code type, and it can permanently change the password repeatedly to change the password. As soon as I run out, I can quickly and safely make changes before I change my habits: two =. In addition, this cylinder lock does not require a low-cost structure for manufacturing a horse lock, but can be constructed with a simple structure. Specifically, the handle-type cylinder lock according to the present invention does not require Because the cylinder lock is replaced after using a limited number of variable lock codes, the fork code can be changed until the life of the cylinder lock, so it is more economical. In addition, even if the remaining key is lost, you do not need to pay attention to the number of password changes that have been made, and you can import a new password. Moreover, even if the key is temporarily lost due to misunderstanding of the user, but the key is found immediately, the original password can be quickly restored. Furthermore, when a manager entrusts maintenance work to a plurality of workers, even when the order of each work is changed or the organization of the work is changed, 'the cylinder lock does not need to be replaced, and it is quick and economical.
