The invention discloses a spring lock with the application publication number of CN102400596A, wherein at least one spring in the spring of the lock is composed of a thick section and a thin section which are coaxial, and the end surface of the thin section of the spring is used as the surface against which the spring and an outer spring are abutted. The two prior arts respectively adopt increasing the secret key amount and changing the depth of the spring groove to enhance the anti-theft effect on the basis of the common spring lock, but essentially still can use the corresponding tool to shift the spring to the proper position to rotate the lock core to unlock.
Disclosure of Invention
In order to solve the problem of poor anti-theft effect of the existing mechanical lock, the invention aims to provide a mechanical lock core with a lock core capable of being separated and independently rotated and a key matched with the mechanical lock core, and the technical scheme is as follows:
the mechanical lock cylinder comprises a lock shell, a rotary lock cylinder and a shifting head, wherein a shifting port is arranged in the middle of the lock shell, and a lock cylinder hole communicated with the shifting port is formed in the lock shell. The shifting block is rotationally arranged in the shifting port, and the rotary lock cylinder is rotationally arranged in the lock cylinder hole. The rotary lock cylinder comprises a plurality of annular rotary lock cylinder shells which are sequentially arranged and a rotary lock cylinder head which is arranged between the shifting head and the rotary lock cylinder shells, wherein the rotary lock cylinder shells and the rotary lock cylinder head are rotatably matched with the hole wall of the lock cylinder hole, and the rotary lock cylinder head is connected with the shifting head through a clutch pin. The outer wall of the rotary lock cylinder shell is provided with arc-shaped limiting grooves, central angles corresponding to the limiting grooves of each rotary lock cylinder shell are different and are all smaller than the angle of rotation required by unlocking the shifting block, and the limiting grooves are communicated with each other. The end face of each rotary lock cylinder shell and the end face of each rotary lock cylinder head are provided with blade jacks, and the blade jacks are connected with each other to form a key hole. The hole wall of the lock cylinder hole is provided with a limiting clamping strip along the axial direction, and the limiting clamping strip is positioned between the limiting grooves of the rotary lock cylinder shells. The outer walls of the rotary lock cylinder shell and the rotary lock cylinder head are respectively provided with a bullet hole communicated with the key hole, and a bullet assembly is arranged in the bullet hole.
Based on the same invention concept, the key matched with the mechanical lock cylinder comprises a core shaft, fixed blades and handles which are respectively connected to two ends of the core shaft, and rotating blades which are rotatably sleeved on the core shaft, wherein the fixed blades can be correspondingly inserted into a rotating lock cylinder head, the number of the rotating blades is equal to that of rotating lock cylinder shells and is arranged in a one-to-one correspondence manner with the rotating lock cylinder shells, and the length of each rotating blade is equal to the thickness of the corresponding rotating lock cylinder shell. The outer wall of the mandrel is provided with arc-shaped rotating grooves along the axis, the number of the rotating grooves is equal to that of the rotating blades, the inner sides of the rotating blades are provided with rotating protrusions which can be inserted into the corresponding rotating grooves, and the degrees of central angles corresponding to the rotating grooves are different and are smaller than the angle of rotation required by unlocking the shifting head. The sum of the degree of the central angle corresponding to each rotating groove and the degree of the central angle corresponding to the rotating lock cylinder shell corresponding to the rotating blade corresponding to each rotating groove is larger than or equal to the rotating angle required by unlocking the shifting block.
Therefore, the shifting block is driven by the rotary lock cylinder head to rotate to a proper angle for unlocking, the rotary lock cylinder head is driven by the key to rotate, and the rotation angle of the key is limited by the rotary lock cylinder shell and the rotary blade. Each rotary lock cylinder shell and the rotary lock cylinder head can independently rotate. The rotatable angle of the rotary lock cylinder head is not limited, the rotatable angle of each rotary lock cylinder shell is limited by the limiting clamping strip and the limiting groove, and the central angles corresponding to the limiting grooves of each rotary lock cylinder shell are limited to be unequal, so that the rotatable angle of each rotary lock cylinder shell is unequal, and a part of a group of unlocking passwords is formed. The central angles corresponding to all the limiting grooves are limited to be smaller than the rotating angle required by unlocking the shifting block, and the effectiveness of the unlocking password of the part is ensured. Accordingly, each rotary blade is rotatably sleeved on the mandrel, and the rotatable angle of the rotary blade is limited by the rotary protrusion and the rotary groove. The fixed blade and the handle are connected respectively at the dabber both ends of key, and the handle pivoted angle is unanimous with the fixed blade promptly. When the key is inserted into the lock cylinder, the fixed blades are inserted into the rotary lock cylinder head, and each rotary blade is correspondingly inserted into the rotary lock cylinder shell at the corresponding position. When the rotating lock is unlocked, the rotating blade rotates around the core shaft, and after the rotating blade rotates to the maximum angle, the rotating blade drives the corresponding rotating lock cylinder shell to rotate until the rotating lock cylinder head drives the shifting block to rotate to the unlocking angle. In this process, the rotating angles of the handle, the fixed blade, the rotary lock cylinder head and the shifting block are consistent and equal to the number of degrees of the central angle corresponding to the rotating groove plus the number of degrees of rotation of the rotary lock cylinder shell, so that the sum of the number of the central angle corresponding to each rotating groove and the number of the central angle corresponding to the rotary lock cylinder shell corresponding to the rotary blade corresponding to each rotating groove needs to be greater than or equal to the angle required by unlocking the shifting block. Similarly, the degrees of the central angles corresponding to the rotating grooves are different and smaller than the angle of rotation required by unlocking the shifting block, so that the other part of the unlocking password is formed, and the effectiveness of the part of the unlocking password is ensured. The lock can be unlocked only when the angle of each rotating blade and the angle of the rotating lock cylinder shell both accord with corresponding values. Because rotatory lock core shell all independently rotates with rotatory lock core head, and the angle of unblanking is the number of degrees of the corresponding central angle of rotation groove plus the number of degrees that corresponds rotatory lock core shell and rotates, so other personnel still can't realize unblanking to corresponding position even stir rotatory lock core shell under the condition of no key to the theftproof effect has been improved. And the unlocking password formed by the rotary lock cylinder shell and the rotary groove is added with the password of the spring lock, so that the difficulty of abnormal unlocking is increased.

Like this through setting up the second lock core in order to make things convenient for indoor personnel to unblank.
The unlocking principle of the embodiment is as follows: the shifting block 3 is driven by the rotary lock cylinder head 22 to rotate to a proper angle for unlocking, the rotary lock cylinder head 22 is driven by the key 4 to rotate, and the rotation angle of the key 4 is limited by the rotary lock cylinder shell 21 and the rotary blade 44. Each of the rotary cylinder housing 21 and the rotary cylinder head 22 is independently rotatable. The rotatable angle of the rotary lock cylinder head 22 is not limited, the rotatable angle of each rotary lock cylinder shell 21 is limited by the limiting clamping strip 13 and the limiting groove 211, and the central angles corresponding to the limiting grooves 211 of each rotary lock cylinder shell 21 are limited to be different, so that the rotatable angle of each rotary lock cylinder shell 21 is different, and a part of a group of unlocking passwords is formed. The central angles corresponding to all the limiting grooves 211 are limited to be smaller than the rotating angle required by unlocking the dial 3, so that the effectiveness of the unlocking code of the part is ensured. Accordingly, each rotary blade 44 is rotatably fitted over the spindle 41, and the rotatable angle of the rotary blade 44 is restricted by the rotary projection 441 and the rotary slot 411. The two ends of the core shaft 41 of the key 4 are respectively connected with the fixed blade 42 and the handle 43, namely, the handle 43 rotates by the same angle as the fixed blade 42. When the key 4 is inserted into the rotary cylinder 2, the fixed blades 42 are inserted into the rotary cylinder head 22, and the rotary blades 44 are inserted into the rotary cylinder case 21 at corresponding positions. When the lock is unlocked by rotation, the rotating blade 44 rotates around the core shaft 41, and after the rotating blade 44 rotates to the maximum angle, the rotating blade 44 drives the corresponding rotating lock cylinder shell 21 to rotate until the rotating lock cylinder head 22 drives the shifting block 3 to rotate to the unlocking angle. In this process, the rotation angles of the handle 43, the fixed blade 42, the rotary cylinder head 22, and the dial 3 are the same and equal to the sum of the degrees of the central angle corresponding to the rotary slot 411 and the degrees of the central angle corresponding to the rotary cylinder housing 21, and therefore the sum of the degrees of the central angle corresponding to each rotary slot 411 and the degrees of the central angle corresponding to the rotary cylinder housing 21 corresponding to the rotary blade 44 corresponding to each rotary slot 411 needs to be greater than or equal to the rotation angle required for unlocking the dial 3. Similarly, the number of the central angles corresponding to the rotating slots 411 is different and smaller than the angle of rotation required by unlocking the dial 3, so that the other part of the unlocking code is formed, and the effectiveness of the unlocking code of the part is ensured. The lock can be unlocked only when the angle of each rotary blade 44 and the angle of the rotary cylinder case 21 both correspond to the corresponding values. Because the rotary lock cylinder shell 21 and the rotary lock cylinder head 22 both rotate independently, and the unlocking angle is the number of degrees of the corresponding central angle of the rotating slot 411 plus the number of degrees of the rotation of the corresponding rotary lock cylinder shell 21, other personnel still cannot unlock even if the rotary lock cylinder shell 21 is shifted to the corresponding position under the condition of no key 4, thereby improving the anti-theft effect. Under the condition of no key, the rotation angle of the rotary lock core is smaller than the rotation angle of the shifting block (namely unlocking), so that the technical unlocking can not be realized without the key, and the unlocking angle can not be reached because the rotation angle is insufficient, and the rotation angle of the key is added to reach the unlocking angle.
