By the safety lock function of an anti-theft door with a latch capable of being locked by the original key, the latch can be unlocked or locked by rotating the front original key for multiple turns, the development of the technology can eliminate the worry of people in door safety protection, and the technology is a scientific research achievement belongs to a revolution in the lock industry of all humans.
Description
(1) technical field
The present invention relates to the improvement invention of all kinds of door lock bodies in market.
(2) background technology
Along with human living standard's raising, pursue daring and luxurious be people's common objective.But, have daring and luxurious all kinds of high, medium and low anti-theft door lock cylinder to control the function technology on world market ancient, traditional dependence two sides color key control coding unlatching or upper security door lock bolt; Perhaps the key operated security door lock bolt of magnetic code, lack and utilize key that the door bolt function is locked in the security door insurance.There is following hidden danger in the technical pattern of controlling the rotation system function singleness for existing lock core; A. this technological development is used with a long history, function singleness, control function no matter increase any insurance, still rely on two sides color key control coding to open and upper lock bolt, this technology has become that specialty is joined the lock technology personnel and social lawbreaker grasps, and it is of common occurrence that these a series of all kinds of safe-guard door locks are unlocked.When b. innocent child plays at home, the safe-guard door lock lock is locked, but child does not understand the method for locking safety latch of how opening yet, child is in alarmed situation often relies on the most dangerous position, such as child stands in behind the door, clashing into forces open the door may hinder child; Perhaps use the pistol drill kind tool to bore door lock, child just listens eccentric sound more can cause child's psychology to be feared to be in to lose one's marbles among alarmed and goes for the danger of outlet.This technological development obviously lacks safety precaution knowledge, allows the owner away from the door have no end of misgivings, and worries that lares et penates becomes safely the whole mankind's common aspiration.Present technique exploitation has solved and has utilized original key that the security door safety latch is locked, use equally original key with safe-guard door lock rotate could allow after more than the border, upper lock bolt puts in place owner relieved away from the door.This technological development has the gesture of following safety function; 1. when the safe-guard door lock insurance is played by child, security door is locked safety latch.But, use original key that security door is locked safety latch in the same old way and open, avoided the accident of meeting accident.2. present technique is controlled the functional structure uniqueness, control system is advanced, having in stronger reply society any unlocking tool of each consummate professional unlocking technique librarian use also can only the unlatching burglar-proof door lock bolt, perhaps unlatching burglar-proof door is locked safety latch, and both can only select to open one security door lock bolt and control function.The exploitation of this technology can be taken precautions against the sorrow that has solved consequence for mankind's door safety, is the scientific achievement that the mankind dream of, and belongs in fact the great revolution that the whole mankind locks industry.
(3) summary of the invention
Defective in view of the prior art existence, the present invention aims to provide a kind of traditional type key unlocking method, set up on lock core and open and the lock insurance function of locking, effectively reach security insurance, have the higher law-breaker that prevents and use all means of destruction opening anti-theft door locks, improve the house safety coefficient, allow the user go out relieved.
The present invention completes by following scheme, a kind ofly utilizes original key to open to lock the safety latch theftproof lock, to comprise lock body, safety latch pressing fork rack, lock core, outside lock core, to lock insurance lock body, insurance lock body control hole; Described lock body holder housing internal cylinder top arranges locks safety latch, before locking safety latch, lock bolt is set, the lock bolt rear end connects the safety latch of locking of moulding, offer recess and hinged safety latch elastic force shift fork yaw pole above locking the insurance breechblock, safety latch elastic force shift fork balance staff is established the inboard hand of position, hole plug-in mounting and is opened axostylus axostyle switch coupling.
The described safety latch below of locking arranges the safety latch pressing fork rack, and the safety latch pressing fork rack inserts lock core through key and rotates and lock safety tongue and promote to lock or open and lock the safety latch coupling.
The Xiamen latch dog is set in described lock body holder housing pushes to snap close unlatching or upper lock bolt active tongue with the latch dog of visiting through key insertion lock core opening switch dead bolt.
Described push rod is cut somebody's hair and is arranged under automatic door bolt shift fork rotating shaft dish along the below of cutting somebody's hair, push to push rod through key insertion lock core rotation opening switch dead bolt and push automatic door bolt shift fork unlatching door bolt automatically aside, automatically square hole plug-in mounting door Internal handle square shaft is established in the rotating shaft of door bolt shift fork, plays at indoor hand and opens automatic door bolt effect.
Described lock core sets up the front of outside lock core and inboard lock core and key separately and opens with the tartar coding.
Described lock core outside lock core inner segment suit is locked the insurance lock body, locks the setting of insurance lock body and locks safety tongue.
The outside lock core of described lock core inserts key operated the locking of reverse side and locks the pressing fork rack unlatching of safety tongue promotion safety latch on the insurance lock body or lock and lock safety latch.
Described insurance lock body and the lock core locked is drilled with insurance lock body control hole, and pellet a, pellet b, pellet c, pellet d and lock the control spring sealing pack in insurance lock body control hole.
Describedly lock insurance and offer stopper slot on lock body and control and lock the insurance lock body and change angle, locking insurance lock body stopper slot top lock core, to establish the spacer pin sealing fixing.
The present invention discloses and a kind ofly utilizes original key to open to lock the safety latch theftproof lock, solve existing all kinds of safe-guard door lock and only established lock bolt controlling organization on the function singleness of traditional type, lack and utilize original key that antitheft door bolt safety lock is locked the door bolt function, reduce greatly the technological deficiency of safe antitheft coefficient.Present technique utilizes original key to lock door bolt security door safety lock function, using the front original key to rotate a few above lock bolts puts in place, the exploitation of present technique can be taken precautions against the sorrow that has solved consequence for mankind's door safety, is the scientific achievement that the mankind dream of, and belongs in fact the great revolution that the whole mankind locks industry.
