Abstract

The utility model discloses a lockset anti-dialing device which comprises a lock shell, a lock tongue and an anti-dialing tongue. A guide column is fixedly arranged inside the lock shell and provided with an anti-dialing piece in a sleeved mode. A side, toward the lock tongue, of the anti-dialing piece is provided with an arc-shaped groove. The anti-dialing piece is provided with a torsional spring. A limiting groove is formed in the lower portion of the anti-dialing tongue. The anti-dialing piece is arranged inside the limiting groove and tightly presses the anti-dialing tongue to the direction of the lock tongue. The guide column is further provided with a position blocking piece. A first sliding rod is fixedly connected with the back end of the anti-dialing tongue. The position blocking piece is provided with a first perforation hole matched with the first sliding rod which penetrates through the first perforation hole. The first sliding rod is provided with a first spring. One end of the first ring is abutted against the position blocking piece, and the other end of the first ring is abutted against the end face of the anti-dialing tongue which is provided with a block receiving part. A position blocking part is arranged on the back side portion of the lock tongue. The block receiving part blocks in an inward contracting pathway of the position blocking part. Compared with a traditional anti-dialing structure, the lockset anti-dialing device is simpler and more effective.

Description

A kind of lockset dial-proof device

Technical field

The utility model relates to a kind of lockset, particularly the dial-proof device in a kind of lockset.

Background technology

All can be provided with dial-proof device in the lockset, to prevent lockset by unnormal unlocking, traditional lockset dial-proof device has very complicated linkage structure, has so greatly increased numerous and diverse degree of lockset, no matter be to producing or to using, all can producing adverse influence.

Summary of the invention

For the deficiencies in the prior art, problem to be solved in the utility model provides the more simple lockset dial-proof device of a kind of structure.

For this reason, the utility model is realized in the following way: a kind of lockset dial-proof device, comprise lock housing, dead bolt and the anti-tongue of dialling, be installed with guide pillar in the lock housing, be set with anti-plectrum on the guide pillar, anti-plectrum has deep-slotted chip breaker towards dead bolt one side, dispose torsion spring on the anti-plectrum, the anti-hypogloeeis of dialling also is provided with stopper slot, and anti-plectrum places in the stopper slot and to the dead bolt direction and compresses the anti-tongue of dialling, also be set with the gear sheet on the guide pillar, the anti-tongue rear end of dialling is fixedly connected with the first sliding bar, and the gear sheet is provided with the first perforation with the first sliding bar coupling, and the first sliding bar passes the first perforation, the first sliding bar is provided with the first spring, the first spring one end withstands on the gear sheet, and the other end withstands on anti-dialling on the tongue end face, and anti-group tongue is provided with and is subjected to stopper, the dead bolt rear lateral portion is provided with gear section, be blocked on the path that gear section inside contracts by stopper.

The gear sheet is Z-shaped, and the dead bolt bottom is fixedly connected with the second sliding bar, also is provided with the second perforation with the second sliding bar coupling on the gear sheet, the second sliding bar passes the second perforation, the second sliding bar is provided with the second spring, and the second spring bottom withstands on the gear sheet, and the other end withstands on the dead bolt end face.

In the utility model, at closing time, dead bolt is pressed in the lock housing, gear section on the dead bolt contacts with the anti-stopper that is subjected to of dialling on the tongue, dead bolt drives anti-group tonguing and enters in the lock housing, when door-closing in-place, dead bolt ejects in the lock tongue slot that enters on the doorframe, the anti-tongue of dialling is pressed in the lock housing by the doorframe face, and the anti-stopper slot of dialling on the tongue is come the deep-slotted chip breaker place of anti-plectrum, and anti-plectrum ejects to the dead bolt direction under the effect of torsion spring, block dead bolt, it can not be entered in the lock housing, reach anti-effect of dialling, this structure is easier than traditional anti-group structure.
