Abstract
The utility model discloses a theft-proof lock which can prevent being opened by a universal key. The problem that the existing theft-proof lock can not prevent being opened by the universal key is solved. The utility model is characterized in that the upper side of a lock body is provided with a groove which is communicated with a trajectory and passes through a lock core, and the inner part of the groove is provided with an L-shaped secondary-control guide rod whose end part is arranged between a cylinder and a spring. When the trajectory of the lock core is over against the trajectory of the lock body, the upper side of the lock core is provided with a groove which is corresponding to the groove of the lock body, and the upper side of the guide rod is provided with a circular arc groove which is corresponding to the lock core. After the universal key is inserted, the whole cylinder is totally pressed into the trajectory of the lock body, and meanwhile, the guide rod is arranged at the position which can not be rotated by the lock core and the theft-proof purpose is achieved.
Description
The utility model relates to a kind of theftproof lock, particularly a kind of theftproof lock that prevents from all pellets shot from a slingshot all are pressed into the lock body trajectory and illegally unblank.
At present, the theftproof lock of selling on the market is various in style, but the structure of its lock core, lock body is mostly basic identical.Its weak point is: when adopting master key to unblank, promptly all pellets shot from a slingshot all are pressed into lock body with master key, and the upper surface that makes pellet shot from a slingshot just in time is on the contact surface of lock core and lock body, at this moment, with the master key rotation, lock core is and then rotation just, and lock is opened the most at last, therefore, existing theftproof lock all can not prevent the unlatching of master key.
The purpose of this utility model is exactly to provide a kind of theftproof lock that prevents unlocked by universal key at above-mentioned weak point.
The technical solution of the utility model is: a kind of theftproof lock, comprise lock core, lock body, dead bolt and controlling organization thereof, it is characterized in that: on described lock body, be provided with the groove that communicates with trajectory and pass lock core, be provided with its end in this groove and be in " L " shape secondary control guide rod between pellet shot from a slingshot and the spring.The trajectory of the trajectory of lock core and lock body over against the time, this lock core is provided with the groove corresponding with the groove of lock body.On secondary control guide rod, be provided with the arc groove corresponding with lock core.
The groove of the lock body in the utility model technical solution, secondary control guide rod can be located on the trajectory of lock body.
The groove of the lock body in the utility model technical solution, secondary control guide rod can also be located on a plurality of trajectories of lock body.
The utility model is owing to be provided with the groove that communicates with trajectory on lock body, be provided with " L " shape secondary control guide rod in the groove, when key is inserted lock core, the end face of pellet shot from a slingshot just in time is on the interface of lock core and lock body, and simultaneously, pellet shot from a slingshot promotes secondary control guide rod and moves down, make the arc groove on it just in time relative with lock core, screw key, lock core just in time rotate in the arc groove of secondary control guide plate, and lock is unlocked.After inserting lock core with master key, in the bullet that whole pellets shot from a slingshot all are pressed into lock body was led, at this moment, pellet shot from a slingshot drove secondary control guide rod and moves down, the arc groove on it can not with lock core over against, lock core can not rotate, lock is not just opened, and has played antitheft effect.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1; And as Figure of abstract.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, have the groove that is connected with trajectory 7 on the lock body 1, lock core 3 is passed on the top of this groove, and secondary control guide rod 5 cooperates with above-mentioned groove, and can move up and down in groove.Secondary control guide rod 5 be " L " shape, and its connecting lever end is in the interior spring 6 of trajectory 7 and up and down between the pellet shot from a slingshot 2,4, and its straight-arm is provided with the groove 8 corresponding with lock core 3.When the trajectory 7 of the trajectory of lock core 3 and lock body 1 during over against the position, lock core 3 is provided with the groove corresponding with the groove of lock body 19.Groove 9, secondary control guide rod 5 can be located at a bullet lead 7 or a plurality of trajectory 7 on.
