The blade marble is connected with a spring, and the spring is installed in the portion, close to a key hole inlet, of the interior of the straight sliding groove. A waisted groove is formed in the lower portion of a cylinder marble, a buckle is arranged on one side of the blade marble, the buckle is buckled on the side wall of the cylinder marble, a rabbet is arranged on the other side of the blade marble, and an annular sliding groove is formed in the portion, located in the blade marble sliding groove, of the inner wall of the lock shell. A bend angle is arranged at one end, away from the spring, of the blade marble, the middle of the straight sliding groove is communicated with a lower groove, the bend angle is located in the lower groove, the width of the lower groove in the key insertion direction is the stroke range of the blade marble, and the inner end of the key hole is communicated with the lower groove. The invention further provides a key used in cooperation with anti-theft lock. By means of the anti-theft lock and the key used in cooperation with anti-theft lock, technical unlocking can be effectively avoided, and anti-theft performance can be promoted.
Description
Technical field
The key that the present invention relates to a kind of Anti-theft lock head and be used in conjunction with.
Background technology
The principle of anti-theft lock end in the market, is all straight-through unlocking structure, and key tooth flower can touch all pellets, so unlocking tool also can once stir all pellets, and this has just left hidden danger to technology unlocking.The defect existing is: theftproof performance is poor.
Summary of the invention
In order to overcome the poor deficiency of theftproof performance of existing theftproof lock, the invention provides and a kind ofly can effectively avoid technology unlocking, the Anti-theft lock head that promotes theftproof performance and the key being used in conjunction with thereof.
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, on described lock core, have keyhole, in described lock core along key direction of insertion at least three cylindrical billiards that are arranged side by side, 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 described close straight runner of keyhole import, the bottom of described cylindrical billiard has waisting groove, one 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 ring-type chute coordinating 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.
And the key that described Anti-theft lock head is used in conjunction with, comprises key body, on described key body, arrange the slip tartar corresponding with cylindrical billiard, described each slip embossing comprises the chute sliding for described cylindrical billiard.
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 will lead directly to release, change release in parallel into, that is to say two lock cores are set in tapered end inside, mutually pin down, must first open one and can open again another one, unlocking tool can only be stirred 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: can effectively avoid technology unlocking, promote theftproof performance.
