Description
Technical field
The present invention relates to a kind of Anti-theft lock head and with the use of key.
Background technology
The principle of anti-theft lock end in the market, be all straight-through unlocking structure, key tooth flower can touch all pellets, and therefore unlocking tool also can once stir all pellets, and this just leaves hidden danger to technology unlocking.The defect existed is: theftproof performance is poor.
Summary of the invention
In order to the deficiency that the theftproof performance overcoming existing theftproof lock is poor, the invention provides a kind of can effectively avoid technology unlocking, promote theftproof performance Anti-theft lock head and with the use of key.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Anti-theft lock head, comprise lock housing and lock core, described lock core is sleeved in described lock housing rotationally, described lock core has keyhole, to be arranged side by side at least three cylindrical billiards along key direction of insertion in described lock core, the lower end of described cylindrical billiard withstands on described keyhole, described tapered end also comprises blade marble, described blade marble in the form of sheets, described lock core outer face has straight runner, described straight runner and described keyhole are arranged in parallel, the inner side of described lock housing has blade marble chute, one end of described blade marble is positioned at described blade marble chute, described blade marble is sleeved in described straight runner slidably, described blade marble is connected with spring, described spring fitting is in the straight runner of described close keyhole import, the bottom of described cylindrical billiard has waisting groove, the side of described blade marble is provided with buckle, described buckle is connected to the sidewall of described cylindrical billiard, the opposite side of described blade marble is provided with tenon, described lock-shell lining is positioned at described blade marble chute place and has the circular track coordinated with described tenon,
Described blade marble is provided with bent angle away from one end of spring, the middle part of described straight runner is communicated with low groove, described bent angle is positioned at described low groove, the width along key direction of insertion of described low groove is the stroke section of described blade marble, and the inner of described keyhole is communicated with described low groove.
With described Anti-theft lock head with the use of a key, comprise key body, described key body arranges the slip tartar corresponding with cylindrical billiard, described each slip tartar comprises the chute for described cylindrical billiard slip.
Further, the end of described key body is provided with blade tartar, and described blade tartar coordinates with the bent angle of described blade marble.
Technical conceive of the present invention is: if straight-through unblock to be changed in parallel unblock, that is two lock cores are set in tapered end inside, mutually pin down, first must open one and can open another one again, unlocking tool can only stir a part of pellet, and technology unlocking difficulty will significantly be improved; How to realize twin-core structure, two lock cores synchronously can be opened again, the invention provides rational solution.
Beneficial effect of the present invention is mainly manifested in: effectively can avoid technology unlocking, promote theftproof performance.
