Description

Technical Field

[0001] The invention relates to the technical field of locks, in particular to a melaleuca lock. Background Art

[0002] As a common item in daily life, locks come in many types. They are a kind of device that plays a sealing role. They are generally composed of a lock body, a lock beam and a lock core assembly. When unlocking, a matching key is required to trigger the switch device in the lock core. The current Thousand Layer Lock uses a lock body composed of a layered steel sheet structure, which makes the lock body have a strong ability to resist impact. When in use, the key is inserted into the connecting sleeve in the lock body, and the switch mechanism is driven to switch when rotating. In order to limit the random rotation of the key, the lock body is equipped with several fixing plates perpendicular to the key insertion direction. Only when the key tooth size corresponds to each fixing plate, the key can be rotated. At present, most Thousand Layer Locks still need to use a matching key to unlock when in use, which is inconvenient to operate. In addition, the Thousand Layer Lock that uses a code wheel as a lock core assembly does not limit the position of the code wheel when adjusting the code. When the code is inaccurate, the code adjustment rod can also be inserted, resulting in a significant reduction in the safety performance of the Thousand Layer Lock. Summary of the invention

A rectangular second opening 84 is provided in the middle of the small shelf 8, and a small spring piece 85 is inserted from the inside to the outside in the second opening 84, and one end of the small spring piece 85 is bent and abutted against the small shelf 8, and the other end abuts against the inner side wall of the Thousand Layer Lock body, providing a fulcrum for the rotation of the small shelf 8. A bending portion 82 and three branch plates 83 are provided at the bottom, and the bending portion 82 is clamped to the outside of the lock core shaft 9, and the branch plates 83 are distributed between the password wheels 96.

[0040] Two short lock cores 91 and two long lock cores 92 are sleeved on the lock core shaft 9. One end of the short lock core 91 and the long lock core 92 is provided with an arc portion, and a flat end surface 9211 is cut on the arc portion. When the flat end surface 9211 rotates to be flush with the branch plate 83, the branch plate 83 rotates inwardly to drive the end 81 of the small frame 8 away from the lock tongue pin 51.

[0041] Specifically, the arc portions of the short lock core 91 and the long lock core 92 are connected, and the short lock core 91 and the long lock core 92 are both provided with symmetrical protrusions 911, and the meshing portion 961 of the code wheel 96 rotates by cooperating with the protrusions 911 on the short lock core 91 and the long lock core 92. A nut 94 is installed at one end of the lock core shaft 9 extending out of the large frame 7, and a lock core spring 95 for reset is installed between the nut 94 and the side of the large frame, and a copper sleeve 93 is installed on the lock core shaft 9 inside the lock core spring 95.

[0042] like Figures 8 to 12 As shown, the unlocking principle; when the four bottom scale lines corresponding to the password wheel 96 are correct, the flat end surfaces 9211 of the arc parts of the short lock core 91 and the long lock core 92 are flush with the branch plate 83 of the small shelf 8. At this time, the end 81 of the small shelf 8 is out of the lock tongue groove, and the lock beam 2 moves upward under the action of the lock beam spring 22, the first lock tongue 5 and the second lock tongue 6 move toward the middle, the lock tongue spring 52 is compressed, and the V-shaped head 61 of the first lock tongue 5 and the second lock tongue 6 is out of the positioning groove 21 of the lock beam 2 to achieve unlocking.

[0043] Locking principle: when any one of the four bottom scale lines corresponding to the password wheel 96 is incorrect, the branch plate 83 of the small shelf 8 is flush with the arc surfaces of the short lock core 91 and the long lock core 92. At this time, the end 81 of the small shelf 8 is stuck in the lock tongue groove, and the first lock tongue 5 and the second lock tongue 6 cannot move toward the middle. The V-shaped head 61 of the first lock tongue 5 and the second lock tongue 6 is stuck in the positioning groove 21 of the lock beam 2, and the lock beam 2 cannot move upward, thereby achieving locking.

[0044] like Figure 13 to Figure 14As shown, the code adjustment process of the Thousand Layer Lock in this embodiment is as follows: turn the code wheel 96 to align the correct code with the scale line at the bottom of the Thousand Layer Lock, press the lock beam 2 hard, the lock beam 2 automatically pops open, then take out the code adjustment rod 4, vertically insert it into the lock hole 12 and press it hard to the bottom, after the code adjustment rod 4 is inserted to the bottom, rotate 180°, align the reset code with the bottom scale line, at this time the password is successfully changed, remember the new password. After the password is changed, turn the code adjustment rod 180°, pull out the code adjustment rod 4, confuse the code, and press the lock beam 2 to lock.

[0045] Code adjustment principle: When all four passwords are correct, the branch plate 83 of the small shelf 8 is flush with the flat end surface 9211, and the bent portion 82 of the small shelf 8 is separated from the lock core shaft 9. At this time, the code adjustment rod 4 can be inserted to abut the nut 94 so that the lock core shaft 9 drives other components to move to the other end, so that the meshing portion 961 is separated from the protrusions 911 of the short lock core 91 and the long lock core 92, and the password can be changed. When the password is not adjusted to the correct one, the bent portion 82 of the small shelf 8 is stuck on one end of the lock core shaft 9, and the password cannot be reset.
