(3) summary of the invention
In view of the defect that prior art exists, the present invention aims to provide the positive and negative key of a kind of traditional type can opening anti-theft door lock, this technical design original key positive and negative is set up and opens and lock door bolt safety latch function, effectively reach security insurance, there is the higher law-breaker that prevents and use all means of destruction opening anti-theft door locks, improve house safety coefficient, allow user go out relieved.
The present invention is completed by following scheme, a kind of anti-theft guard door lock, comprises lock core body, outer lock core, insurance shift fork sleeve, bit selecting pellet, selects pellet, insurance shift fork, insurance declutch shift shaft, drag hook, described lock core body arranges outer lock core and internal cylinder, lock core body and outer lock core and internal cylinder arrange several marble holes, and pellet and upper pellet and spring seals under loading in each marble hole, outer lock core inner segment suit insurance shift fork sleeve, on insurance shift fork sleeve, disjunctor arranges insurance shift fork, insurance shift fork sleeve body establishes spacing hole and marble hole, location pellet sealing is loaded at spacing hole, play rotation-limited effect, insure marble hole and lock core body marble hole and outer lock core inner segment marble hole on shift fork sleeve require to keep vertical and load bit selecting pellet and select pellet and press position pellet and spring seals, described lock core body stage casing dead bolt shift fork rotates the row's of unlatching door bolt and bolt hook a, bolt hook b, and key another side opening safety shift fork rotates drag hook band reinsurance door bolt.
On described insurance shift fork sleeve, disjunctor arranges insurance shift fork, and insurance shift fork top is set to semicircle hook-shaped.
Described drag hook profile design is that upper end is bending like sickleshaped, lower end is set to carpenter's hammer shape.
Described bit selecting pellet is specially recognized spring concealed puzzle pit and is mated with original key another side is established.
The present invention discloses a kind of anti-theft guard door lock, solve lock bolt controlling organization in function singleness that existing goods room Mechanical theft-proof door lock only establishes traditional type, lacking utilizes original key that antitheft door bolt safety lock is locked door bolt function, reduces the technological deficiency of safe antitheft coefficient greatly.This technology utilizes original key to lock door bolt security door safety lock function, use front original key to rotate a few above lock bolts to put in place, the exploitation of this technology can take precautions against for the mankind's door safety sorrow solving consequence, is the scientific achievement that the mankind dream of, belongs to the great revolution that the whole mankind locks industry in fact.
