SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a simple to operate, safe and reliable's vehicle anti-theft device, the utility model discloses a theftproof lock core for car door.
The utility model discloses a following technical scheme reaches the invention purpose:
the utility model provides a theftproof lock core for car door, includes the casing, characterized by: also comprises a lock column, a lock column spring, a lock core, an anti-drilling sheet, a transmission paddle seat and a transmission paddle,
the shell is tubular, ear plates are arranged on two sides of the shell, and the shell is fixed on an automobile door through the ear plates;
the lock core is sleeved in the shell, the head of the lock core is provided with a reserved groove, the anti-drilling piece is embedded into the lock core through the reserved groove, and when a key matched with the lock core is inserted into the lock core and rotates, the anti-drilling piece and the lock core synchronously rotate relative to the shell;
the lock core is provided with at least three lock cylinder holes, each lock cylinder hole is internally provided with a lock cylinder and a lock cylinder spring, the bottom end of each lock cylinder spring is propped against the bottom end of the corresponding lock cylinder hole, the top end of each lock cylinder spring is propped against the bottom end of the corresponding lock cylinder, and the number of the lock cylinders and the number of the lock cylinder springs are equal and are not less than three;
the lock core is connected with the transmission paddle through the transmission paddle seat, and the transmission paddle is driven to synchronously rotate through the transmission paddle seat when the lock core rotates.
The anti-theft lock cylinder for the automobile door is characterized in that: the lock cylinder and the lock cylinder spring are equal in quantity and are not less than eight, and the anti-drilling piece is made of high-carbon steel with high hardness.
When the utility model is used, when no key is inserted into the lock core, the lock column is clamped in the key groove of the shell under the action of the spring force of the lock column; when a key which is not matched with the lock core is inserted into the lock core, the lock cylinder can not be completely retracted into the lock core, and the lock core can not rotate; when a key matched with the lock cylinder is inserted into the lock cylinder, all the lock cylinders retract into the lock cylinder, the shell removes the fixation of the lock cylinder, the lock cylinder is rotated by the key, and then the transmission paddle is driven by the transmission paddle seat to rotate together, so that the vehicle door is unlocked.
The utility model discloses following beneficial effect has:
1. by adding the anti-drilling piece with high hardness at the head of the lock cylinder, when the lock cylinder is drilled by a drill bit, the marble in the lock cylinder can be protected from being damaged, and the lock cylinder is further prevented from being unlocked.
2. By using the method of embedding the anti-drilling piece in the head part of the lock cylinder, the structure of the lock cylinder is not basically changed, and the cost is low.
