Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is to provide 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 anti-dial tongue, it is characterized in that: lock housing internal fixtion is provided with guide pillar, guide pillar is set with anti-plectrum, anti-plectrum has deep-slotted chip breaker towards dead bolt side, anti-plectrum is configured with torsion spring, anti-dial hypogloeeis is also provided with stopper slot, anti-plectrum to be placed in stopper slot and to compress anti-dial tongue to dead bolt direction, guide pillar is also set with paddle, anti-dial tongue rear end is fixedly connected with the first sliding bar, paddle is provided with first boring a hole of mating with the first sliding bar, first sliding bar is through the first perforation, first sliding bar is provided with the first spring, first spring one end withstands in paddle, the other end withstands on anti-dial tongue end face, anti-dial tongue is provided with by stopper, dead bolt rear lateral portion is provided with gear part, be blocked on the path that gear part inside contracts by stopper, when door-closing in-place, dead bolt ejection enters in the lock tongue slot on doorframe, anti-dial tongue is pressed in lock housing by doorframe face, stopper slot on anti-dial tongue comes the deep-slotted chip breaker place of anti-plectrum, anti-plectrum ejects to dead bolt direction under the effect of torsion spring, block the gear part of dead bolt.
Paddle is Z-shaped, and dead bolt rear end is fixedly connected with the second sliding bar, paddle is also provided with second boring a hole of mating with the second sliding bar, second sliding bar is through the second perforation, second sliding bar is provided with the second spring, and the second spring bottom end withstands in paddle, and the other end withstands on dead bolt end face.
In the present invention, at closing time, dead bolt is pressed in lock housing, gear part on dead bolt and contacting by stopper on anti-dial tongue, dead bolt drives anti-dial tonguing to enter in lock housing, when door-closing in-place, dead bolt ejection enters in the lock tongue slot on doorframe, anti-dial tongue is pressed in lock housing by doorframe face, and the stopper slot on anti-dial tongue comes the deep-slotted chip breaker place of anti-plectrum, and anti-plectrum ejects to dead bolt direction under the effect of torsion spring, block dead bolt, make it can not enter in lock housing, reach anti-dial effect, this structure is easier compared to traditional anti-dial structure.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention;
Fig. 2 is the schematic diagram of anti-dial tongue;
Fig. 3 is the top view of Fig. 2.
