Detailed Description
Referring to fig. 1 to 5, the present invention discloses a simplified version of a master-slave blade lock comprising a lock housing 1, a lock cylinder 2, a master blade 3, a slave blade 4, a lock bolt 5 and a key 6.
The lock housing 1 has a cylindrical cavity 11 and a lock bolt recess 12.
The lock cylinder 2 is rotatably inserted in the cylinder chamber 11. The key cylinder 2 is formed with a blade mounting groove 21, a plug hole 22, and a main key hole 23.
The busbar sheet 3 is inserted in the busbar sheet mounting groove 21. The master batch 3 is formed with a master batch slot 31, a first key hole 32 and a first key slot 33. The first key hole 32 has first lock teeth 34 formed therein. The sub-row sheet 4 is inserted in the sub-row sheet groove 31. A second keyhole 41 and a second key slot 42 are formed in the sub-row plate 4. The second key hole 41 has second lock teeth 43 formed therein. A row spring 7 is arranged between the master row sheet 3 and the lock cylinder 2 and between the sub row sheet 4 and the lock cylinder 2. For convenient installation and positioning, the lock cylinder 2 is provided with a row spring hole 24 at the side edge of the row sheet mounting groove 21, a first spring column 36 is formed at the side edge of the busbar sheet 3, a second spring column 44 is formed at the side edge of the sub-row sheet 4, and the row sheet spring 7 is arranged in the row spring hole 24 and is abutted against the first spring column 36 or the second spring column 44.
The lock bolt 5 is inserted into the lock bolt hole 22, and a lock bolt return spring 51 is provided between the lock bolt 5 and the lock cylinder 2.
The key 6 has a plunger 61 that can be inserted into the main key hole 23, the first key hole 32 and the second key hole 41, and double rows of internal teeth 62 are formed on the plunger 61, and the double rows of internal teeth 62 can cooperate with the first lock teeth 34 of the busbar sheet 3 and the second lock teeth 43 of the child row sheet 4 to drive the child row sheet 4 and the parent row sheet 3, so that the first lock bolt slot 33 and the second lock bolt slot 42 are aligned with the lock bolt hole 22, and unlocking is achieved.
When the locking state or the key is incorrect, the first bolt grooves 33 of the busbar sheet 3 and the second bolt grooves 42 of the subrow sheet 4 are not aligned with the bolt holes 22 in the center, and the bolts 5 cannot fall into the first bolt grooves 33 and the second bolt grooves 42 and are blocked in the bolt grooves 12 of the lock shell 1, so that the lock cylinder 2 cannot rotate. When the correct key 6 is inserted, the double-row internal tooth flower 62 drives the child row plate 4 and the mother row plate 3 to compress the row plate spring 7 to displace, so that the first latch groove 33 and the second latch groove 42 are aligned with the latch hole 22 in the center, and when the key 6 is turned again, the lock cylinder 2 can be driven to rotate, the latch 5 is pushed to compress the latch reset spring 51 to withdraw from the latch groove 12 and fall into the first latch groove 33 and the second latch groove 42, and thus the latch reset spring leaves the latch groove 12 of the lock case 1, so that the key 6 can drive the lock cylinder 2 to rotate for unlocking.
In order to further improve the safety performance, anti-poking grooves 35 and 45 are correspondingly formed on the main row sheet 3 and the sub row sheet 4, an anti-drilling sheet groove 25 is formed on the rear side of the main key hole 23 by the lock cylinder 2, the anti-drilling sheet 8 is inserted into the anti-drilling sheet groove 25, a third key hole 81 is formed in the anti-drilling sheet 8 for allowing a plug rod 61 of a key 6 to pass through, and the anti-drilling sheet 8 can play a role in anti-drilling and anti-sawing.
The busbar sheet 3 and the child row sheet 4 form a double-layer password, are extremely difficult to be opened by technology, have high safety performance, can be made of stainless steel, have high strength, are wear-resistant and corrosion-resistant, and are not easy to copy due to the fact that the busbar sheet 3 and the child row sheet 4 are made of the stainless steel, and the key 6 with the double-row internal teeth 62 is provided. The number of the row sheets of the invention determines the number of the dental floss, taking 7 groups of row sheets as an example, if the angle of the mother row sheets 3 and the child row sheets 4 is changed by 4, and 14 row sheets are arranged in total in the 7 groups of row sheets, the dental floss number is 14 times of 4, namely: 2.6 hundred million. The lock can greatly improve the safety.
Compared with the traditional primary and secondary blade locks, the invention has the advantages that: (1) The master row sheet 3 and the sub row sheet 4 of the invention form a whole group of row sheets, the structure is simpler, while the master row sheet and the sub row sheet of the traditional master-slave blade lock only form a small group of row sheets, and then the two small groups of row sheets can form a whole group of row sheets, so the structure is more complex; (2) The busbar sheet 3 and the busbar sheet 4 of the invention are not in directions, can be assembled up and down, and cannot distinguish the busbar sheet 4 and the busbar sheet 3 from the appearance of the finished product lock, so that the technical opening can be prevented, while the positions of the busbar sheet and the busbar sheet of the traditional master-slave blade lock are fixed, and the busbar sheet can be distinguished from the appearance of the finished product lock, so that the technical opening is easy; (4) The key 6 of the invention adopts double rows of internal teeth 62, which is extremely difficult to copy, while the key of the traditional primary-secondary blade lock adopts four rows of two layers of external teeth, which is difficult to copy; (4) The busbar sheet 3 and the child row sheet 4 can be formed by stamping, so that the cost is low, and the busbar sheet of the traditional child-mother blade lock adopts powder injection, so that the cost is high.
