Description

Anti-theft lock end

The utility model relates to a kind of theftproof lock, especially a kind of anti-theft lock end.

Lock commercially available at present and that use all is made up of lock core, tapered end, lock shaft and lock housing, is provided with pellet shot from a slingshot and spring between lock core and tapered end.Tapered end upper lock core and pellet shot from a slingshot directly expose, and are easier to detect pellet shot from a slingshot assembling situation and more easily stir pellet shot from a slingshot from lockhole (keyhole), and a lot of people are easier to no key unlocking technology lock be opened, and lose the anti-theft feature of lock.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and is difficult to survey pellet shot from a slingshot assembling situation, the anti-theft lock end that no private key can't be opened from lockhole.

The purpose of this utility model realizes by following technical proposals: inner prop and the column jacket piece of being with keyhole on tapered end by clamping ring affixed, interior column jacket piece upper side is provided with a groove opposite, inner prop is provided with two cylinders and is with two grooves, the slide plate of keyhole and dog is pegged graft, other establishes the rotating cylinder of a band keyhole, the spring above the rotating cylinder body inwall and the slide plate edge of dog side offset, the rotating cylinder body is provided with two through holes and two affixed covering on interior column jacket piece and the slide plate of cylinder, lateral margin is provided with a loam cake Connection Block on the rotating cylinder, and it is hinged by bolt and loam cake plush copper, loam cake is provided with a shell fragment hook or a carbine with the corresponding position of keyhole on the rotating cylinder, the hook end is corresponding with the hole on the key that inserts in the keyhole, so that loam cake is taken key out of by slip hook when opening.

Said tapered end, lock core and inner prop and column jacket piece also can be by fastening the nail riveted joint or the two being designed to one respectively.

Earlier loam cake is opened during use, by plush copper on the loam cake slide plate dog is pushed in the post piece groove, the slide plate keyhole is alignd with keyhole on rotating cylinder, inner prop and the lock core, insert no handle key, shut loam cake, by slip hook key is pushed into below the slide plate, at this moment, rotates rotating cylinder, the inwall upper spring is released column jacket piece groove with the slide block dog and is rotated rotating cylinder by hand, drive key turns and lock opened, when opening loam cake again, on the slip hook hook end hook that covers firmly do not have handle hole and key is taken out of on the key.

The utility model is inner prop and the column jacket piece by setting up on tapered end mainly, increase tapered end length, make the pellet shot from a slingshot assembling situation between tapered end and lock core be difficult to be detected, stir, strengthen the anti-theft feature of lock, the slide plate that while the utility model is set up, when loam cake is opened by loam cake on plush copper slide plate is passed, its dog is embedded in the column jacket piece groove, lock core can't be rotated, open, promptly use private key also can't rotate, have only loam cake is covered, rotating cylinder inwall upper spring is released column jacket piece groove with dog and is entered inner prop piece groove, can open lock by the rotation rotating cylinder, from above-mentioned situation as can be known, the utility model purpose can realize that compared with prior art it has following advantage: (1) no key unlocking technology is powerless to the utility model, has improved the anti-theft feature of lock; (2) be difficult to from keyhole, detect pellet shot from a slingshot assembling situation and stir pellet shot from a slingshot, really reach anti-theft effect.
