Description
Technical field
The present invention 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, the problem to be solved in the present invention provides the more simple lockset dial-proof device of a kind of structure.
For this reason, the present invention realizes in the following way: a kind of lockset dial-proof device, comprise lock housing, dead bolt and the anti-tongue of dialling, it is characterized in that: 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 and is in impaction state in the stopper slot, also be set with the gear sheet on the guide pillar, the anti-end, hypogloeeis 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, dead bolt 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 present invention, 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.
