[Previous technology] A conventional replaceable key lock, such as the US-issued US Pat. No. 6,860,131 and the US Patent No. US 2G_2 772, the replaceable key lock, in the step of replacing a new key, It is not necessary to insert the new key into the positioning (ie, insert it to the end) and then re-spin the new lock code to actually complete the key replacement procedure. However, the conventional design of the replaceable lock lock core structure may be because the general user does not insert the new key into the position to rotate the lock in the step of replacing the new lock #. The guide spider has not actually completed the key replacement. Before the program, the key is rotated, and the subsequent user inserts the new key into the positioning (ie, 褚^^ exactly), the error still cannot be unlocked normally. Therefore, how to ensure that the user must insert the new key into the positioning. The key replacement operation can be performed in the state of being inserted into the bottom, which is an extremely important issue in the structural design of the replaceable key lock. SUMMARY OF THE INVENTION [0003] The main object of the present invention is to provide a lockable replaceable key lock, which comprises a lock case, a lock set disposed in the lock case, and a foolproof component.

The straight slot 12 is used to set the hot one and the ice 12b. In this embodiment, the system has an upper slot. Both the portion 12a and the lower groove have an inner diameter of the locking bead hole 11, and the inner diameter of the lower upper groove portion 12a is smaller than the inner diameter of each of the > β 12 a, and the inner diameter of the restricting groove portion 12b is Less than the upper slot period n / magnetic portion l2be, please refer to the first and third slots 13 connected to the straight slot 12 of the 卞 1 ^ 仁本 贌 21, a plurality of combinations and 4 diagrams, the lock group 20 series includes a kicking block 23 in the 〇 21 21, the lock bead 22 and a lock ♦ / keyhole m, a plurality of lower body bodies 21 have - outer side wall, lock hole 211 through lock Bead hole 212, one connected to the outer side 今 2 today lock The keyhole 2 ΐ ι 容 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 201118227 has an angle θ ' and the valley groove 214 corresponds to the limit slot 13 of the s-lock case iq, please refer to the figures 1 and 4 respectively. The combined lock beads 22 are respectively disposed on the In the present embodiment, the combination bead 22 is a height adjustable ball bead and each of the combination bead 22 includes a first toothed part. a second toothed member 222 that is engageable with the first toothed member 221 and an elastic member 223 disposed between the first toothed member 221 and the second toothed member 222. In the embodiment, the positioning block 23 has a tool hole 231 for inserting a replacement key tool (not shown). In addition, please refer to the figures 1, 3 and 4, in order to improve the security and safety of the lock core, the lock group 20 of the present invention may further comprise an anti-theft member 50, and the anti-theft device 50 is disposed on the lock body In the embodiment, the anti-theft member 50 can be moved to the limiting slot 13 of the locking case 10 when the locking core is subjected to a locking element to limit the locking. The group 20 rotates. Please refer to the first and third figures. The anti-slipping component 30 includes a limiting member 31 and a topping member 32. The limiting member 31 is disposed on the straight slot 12 of the locking case 10, and the limiting position is The member 31 has an upper rod portion 31a and a lower rod portion 31b. In the embodiment, the upper rod portion 31a is located in the upper groove portion 12a of the straight groove 12, and the lower rod portion 31b is threaded through the straight portion 31b. The lower groove portion 12b of the groove 12 and the limiting groove 13, and the diameter of the upper rod portion 31a is larger than the diameter of the lower rod portion 31b, and the abutting member 32 is disposed at the through hole of the lock body 21. 213, and the abutting member 32 has a first end 32a, a second end 32b opposite to the first end 32a, and a positioning groove 32c' recessed in the first end 32a under normal operating conditions. The second end 32b of the abutting member 32 abuts the anti-theft member 5〇. The description of the action of the foolproof component 3 of the present invention is as follows 098140852 Form No. A0101 Page 6 of 27 0982070132-0 201118227 . First, please refer to page 54 and the redundancy diagram. When the key is to be replaced, the first matching key 70 is first inserted into the key hole 211 of the lock body 21; then, refer to Figures 6A and 6B to rotate the key The first matching key 70 drives the lock body 21 and the positioning block 23 to rotate to a predetermined angular position (ie, the position of the key can be replaced). In this embodiment, the first matching key is rotated 45 degrees clockwise. At the same time, the limiting member 31 of the foolproof component 30 is selectively movable into the through hole 213 and abuts the top member 32 ′ to restrict the rotation of the locking group 20 relative to the locking case 10 . In this step, the first end 32a of the abutting member 32 faces the limiting member 31, and one end of the limiting member 31 abuts the positioning groove 32c of the abutting member 32; 7A and 7B' insert a replacement key tool 80 into the tool hole 231 of the positioning block 23 to disengage the second toothed members 222 from the first toothed members 221; 8A and 8B, the first matching key 70 is extracted, and at this time, the second tooth positions of the combined locking beads 22 2 2 2 and the top member 3 2 of the foolproof component 30 will fall to the lowest position, and the lower portion of the limiting member 31: 3ib#, the luxury of the lock body 21 The hole 213 is configured to limit the lock body to prevent the lock body 21 from being rotated; afterwards, refer to FIGS. 9A, 9A and 9C, and insert a second matching key 90 into the lock hole of the lock body 21. 211. In this embodiment, when the second matching key 90 is inserted into the positioning (ie, inserted into the bottom), the second positioning members 222 of the combined locking beads 22 follow the second matching lock. The height of the tooth peaks of 90 is different and the height is adjusted again, and the topping member 32 of the foolproof component 30 is pushed by the pushing portion 90a of the second matching lock 90 to return to the rotating interface. In this embodiment, the pushing portion 90a of the second matching key 90 can selectively push the top abutting member 32, and preferably, the pushing portion 9a of the second matching key 90 The system is inclined 098140852 Form No. A0101 Page 7 / Total 27 pages 0982070132-0 201118227, at the same time, the limit w can release the limit of the lock body 21 Subsequent replacement of the key program, otherwise, please refer to the first and (10) diagrams. When the second matching key 90 is not inserted into the positioning position (ie, not inserted into the bottom), the second matching key 9〇 of the pushing portion 9〇a The top member 32 of the foolproof component 30 cannot be pushed back to the rotating interface. At this time, the lock body 21 will be restricted by the limiting member 31 of the foolproof component 30 and cannot be rotated. And the key replacement procedure will not continue. Next, referring to FIGS. 10A and 10B, after the second matching key 90 is inserted into the positioning, the replacement key tool 80 is extracted to make the second toothed parts 222 and the The first toothed members 221 are re-engaged; after that, please refer to the second and second figures to rotate the second matching key 9〇 to return the lock to the normal use shape I, and protect the scope of the invention. Subject to the patent application, any change or modification made by the person who is familiar with the art without departing from the scope of this issue shall be in the heart of the month.
