Technical Field
The invention relates to the technical field of hardware power transmission, in particular to an anti-theft lock cylinder.
Background
The lock is that every family of family all needs to use today, and the most common is used in on the door, utilizes the lock to play the effect of guarantor, and the theory of operation of lock is very simple, utilizes the pellet shot from a slingshot to connect the dislocation joint between lock core and the lock body, can be with going up pellet shot from a slingshot and separating the position with lower pellet shot from a slingshot separately and be located the gap department between lock core and the lock body when the key inserts, can rotate the key this moment and open the door, but this kind of principle has appeared a lot of technical unlocking illegal events after disclosing:
Because the design is based on the dislocation clamping mode of the marble, so that many lawlers can use an unlocking tool to jack the marble and judge whether to jack the marble to a separation position according to twisting the lock cylinder. Then, slowly trying until all the marbles are pushed to the same position, and then unlocking can be caused, so that a lot of burglary situations can be caused; moreover, in general, due to the fact that the same type of key has different specifications and the concave-convex tooth parts are different, a person who has a plurality of locks of the same type can easily insert wrong keys, the key can be bent by forcibly twisting the key when the person carelessly wants to, and the key can be twisted off vigorously, so that the key core can not be clamped into the lock core when the person cannot open the door, a professional person needs to be asked to unlock the lock, and the lock is more troublesome and time-consuming and economical.
Disclosure of Invention
Aiming at the defects of the background technology, the invention provides the anti-theft lock cylinder which has the advantages of safety and wrong key insertion prevention and solves the problems in the background technology.
The invention provides the following technical scheme: an anti-theft lock core comprises a lock body and a lock core, wherein the lock core is movably sleeved inside the lock body, a circle of rotating ring groove is formed in the inner ring of the lock body, a first marble hole is formed in the top of the interior of the lock body, an upper marble connected through a spring is movably sleeved in the first marble hole, a key hole is formed in the middle of the lock core, a second marble hole matched with the first marble hole is formed in the top of the interior of the lock core, a lower marble is movably sleeved in the second marble hole, a sliding groove is formed in the back of the second marble hole of the lock core, a butting contact is movably installed at the top of the sliding groove, a limiting block matched with the sliding groove is fixedly installed at the bottom of the back of the lower marble, a hydraulic hole channel is formed in one side of the interior of the lock core, which is as high as the butting head, the end of the hydraulic hole is movably sleeved with the butting head, hole, the middle part of the hydraulic pore canal is movably sleeved with a rotation limiting device, a communicating hole is arranged in the rotation limiting device and is communicated with the two ends of the hydraulic pore canal, and one side of the rotation limiting device extends out of the rotation ring groove.
Preferably, the inside both sides of lock core are located the position of hydraulic pressure pore below and have seted up movable inner chamber, and the fixed orifices has been seted up to one side of lower pellet shot from a slingshot, and the spacing groove has been seted up to the opposite side of lower pellet shot from a slingshot, and the middle part movable mounting of activity inner chamber has the dwang, and the one end swing joint of dwang has the card axle, and the other end swing joint of dwang has the activity to be supported the head, and the activity is supported fixedly connected with compression spring between the one end.
Preferably, the width of the rotating ring groove at the extending end of the rotation limiting device is increased, the length of each sliding groove is the distance from the top of the shortest lower marble to the surface of the outer ring of the lock core, the number of the shortest lengths of the lower marbles is two, the collision heads are arranged at the top of the sliding groove corresponding to the shortest lower marble, and the top of each limiting block is provided with an inclined chamfer.
Preferably, the hydraulic pore canal is filled with hydraulic oil, a certain unfilled space is reserved at the positions of two ends, the sleeve joint of the abutting contact and the hydraulic pore canal is sealed, and the diameter of the hydraulic pore canal and the inner diameter of the rotation limiting device are reduced.
Preferably, one movable inner cavity corresponds to the positions of the two lower marbles, the diameter of the fixing hole is larger than that of the end part of the clamping shaft, and the length of the limiting groove is equal to that of the sliding groove.
The invention has the following beneficial effects:
compared with the prior art, the lowest lower marble is pushed to the unlocking position and simultaneously pushes the abutting contact, so that the rotation limiting device can be ensured to be positioned in the middle part and not to deviate through the pressure transmission of the hydraulic oil hole so as to rotate the lock core, when other tools are used for unlocking, the simultaneous pressing of the two position contact heads cannot be ensured, so that the rotation limiting device can deviate and cannot be completely matched with the rotating ring groove, the lock core cannot be rotated, the theft condition of lawless persons is effectively prevented, meanwhile, the lock is matched with the clamping shaft and the movable abutting head, so that the key can be inserted only when the key meets the standard, otherwise, the key cannot be pushed up to remove the marble when being inserted, and the damage condition of the key and the lock cylinder caused by inserting a wrong key is avoided.
