Description
Technical Field
The invention belongs to the technical field of anti-theft locks, and particularly relates to a safe anti-theft lock.
Background
Along with the increasing living standard and the accelerating pace of life, the prevention consciousness of people is also strengthened increasingly. Therefore, the anti-theft locks sold on the market are various, and have different design concepts, so that the anti-theft requirements of different users can be met.
The cylinder lock is the most commonly used lock, and is suitable for the inner and outer doors of various buildings. Generally, a pin tumbler lock comprises two main body components, namely a fixed lock cylinder and a movable lock cylinder. The fixed lock core and the movable lock core are respectively provided with a plurality of corresponding radial marble holes, and a flat marble and a round marble are placed in each marble hole. An elastic device is also arranged in the marble hole of the lower lock core, so that the flat marble is tightly attached to the round head marble. In the locking state, the flat head marble is clamped at the interface of the fixed lock core and the movable lock core. The outer end face of the movable lock core is provided with a key hole, and when a matched key is inserted into the key hole, the round head marble in the marble hole of the upper lock core can be extruded by the key hole of the key to move towards the flat head marble, so that the contact surface of each flat head marble and the round head marble forms a cylindrical surface and is flush with the interface surface of the fixed lock core and the movable lock core, and an opening state is formed. In this state, the key can rotate the movable lock core to open the spring lock. If a key is not put in or a key which is not matched with the movable lock core is put in, the flat head marble is clamped at the joint surface of the fixed lock core and the movable lock core under the pressure of the elastic device, the movable lock core cannot be rotated by the key, and the lockset cannot be unlocked.
However, in the existing spring lock, the springs in the lock are all arranged in the cavity of the key hole in order that the key can be inserted into the key hole and then can be pressed against the springs, so that a theft perpetrator can insert into the key hole through a master key or other unlocking tools to contact and press the springs to unlock the lock, the anti-theft performance of the existing spring lock is not strong, the popularization and the application of the anti-theft lock are restricted, and potential safety hazards exist.
Disclosure of Invention
In order to make up the defects of the prior art, the invention provides the safe anti-theft lock which solves the problems that the prior spring lock can press the springs after a key is inserted into a key hole, and the springs in the lock are all arranged in a cavity where the key hole is positioned, so that a theft perpetrator can insert into the key hole through a master key or other unlocking tools, and contact and press the springs to unlock the lock, the anti-theft performance is not strong, the popularization and the application of the anti-theft lock are restricted, and potential safety hazards exist.
The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a safe anti-theft lock, which comprises a lock body, wherein a lock hole arranged in the lock body is rotationally connected with a lock cylinder, and a lock hole is arranged in the lock cylinder; a group of first sliding holes are formed in the inner wall of the lock hole, second sliding holes are formed in the positions, corresponding to the first sliding holes, of the lock core, and the second sliding holes are communicated with the lock hole; a first marble is connected in the first sliding hole in a sliding manner, and a second marble is connected in the second sliding hole in a sliding manner; one end of the first marble, which is far away from the second marble, is sequentially provided with a spring and a blocking core, and the blocking core is used for blocking the first sliding hole; one end of the lock cylinder is provided with a square connecting column; a protective cover is arranged on the lock body at one end of the lock cylinder, which is far away from the connecting column, a cavity is formed in the protective cover, and a jack is formed in the position, corresponding to the lock cylinder, of the protective cover; a plugging disc is hinged in the cavity through a connecting rod, and the plugging disc plugs the insertion hole after rotating; an arc-shaped magnetic block is arranged on one side, away from the hinged part, of the blocking disc; during operation, use the key to insert the keyhole and rotate the back and pin the pickproof lock, then extract the key, use inlaid magnet on the key handle to be close to the shield and correspond the position with the magnetic path, attract the magnetic path through removing the key, and then plug up the jack after driving the closure plate rotation, increase the degree of difficulty that the keyhole inserted the key, increase the degree of difficulty and the time that the illegal personnel pried the pickproof lock, and then increase the risk that exposes when illegal personnel worked on a case, make illegal personnel give up and pick the lock, further increase the theftproof ability of pickproof lock.
Preferably, a third sliding hole is formed in one side, close to the lock body, of the cavity, and a sliding column is connected in the third sliding hole in a sliding mode; a spring is arranged between the sliding column and the bottom of the third sliding hole, a magnetic head is arranged at one end of the sliding column, which extends out of the third sliding hole, and the magnetic pole of one side of the magnetic head, which is close to the jack, is opposite to the magnetic pole of one side of the magnetic block, which is close to the jack; the blocking disc is provided with a clamping hole; the sliding column is used for being clamped in the clamping hole when the plug disc blocks the jack; when the jack is plugged after the blocking disc rotates, the blocking disc rotates to the corresponding position of the sliding column, the sliding column is nailed into the third sliding hole through the blocking disc, the blocking disc continues to rotate, the clamping hole rotates to the corresponding position of the sliding column, the sliding column is popped out under the action of the spring and then clamps the clamping hole, the plugging capacity of the blocking disc to the jack is further enhanced, when the lock is needed to be unlocked, the magnet embedded on the key handle is close to the corresponding position of the sliding column, the magnet pushes the magnetic head open, the sliding column is further pushed out from the clamping hole, then the blocking disc can be rotated by moving the key, the jack is exposed, and the unlocking operation is carried out.
