Operating principle of the present invention
The insurance course of work that automatically locks when closing:
When little dead bolt 18 is run into doorframe, little dead bolt 18 moves under the extruding of the reaction force of doorframe backward, being sleeved on little dead bolt 18 rear end cylinder inclined boards moves piece 15 and moves backward simultaneously, swash plate moves rearward end roof pressure latch 9 afterbodys of piece 15, drive latch 9 heads and break away from big dead bolt 1 prelocalization insurance hole 1a, make latch 9 be in open mode, big dead bolt first torsion spring 41 originally, big dead bolt second torsion spring 42 present duties, at this moment, in a single day latch 9 heads leave prelocalization insurance hole 1a, big dead bolt 1 is at big dead bolt first torsion spring 41, automatically stretch into the outer surely hole of doorframe on the doorframe under the pressure of big dead bolt second torsion spring 42, latch 9 automatically resets under the compression of compressing spring 8, latch 9 heads insert location, back insurance hole 1b makes big dead bolt 1 be in the locking safety position, increases by a cover pick-proof measure again, reaches safe and reliable.
Open the door and use the course of work of key:
Inner lock head 192, outer tapered end 191 all uses same key 193 to open, key 193 insert in inner lock heads 192 or outer tapered end 191 holes respectively to clockwise or be rotated counterclockwise in lever arm 6, interior lever arm 6 has outward extending three dogs, and wherein first dog 61 matches with the shoulder of latch 9;
Second dog 62 matches with big dead bolt 1 groove shoulder, and the 3rd dog 63 matches with swing arm 5; First dog 61 drives latch 9, opens night bolt 9 simultaneously, and second dog 62 drives big dead bolt 1 and moves backward; The 3rd dog 63 is stirred the second protruding arm 5b of the swing arm 5 that is positioned on the reference column 21 from bottom to top, swing arm 5 is center of circle rotation with reference column 21, the first protruding arm 5a of swing arm 5 stirs the little dead bolt 18 of guide-localization spare 17 drives and moves backward, big dead bolt 1 moves backward to desired location simultaneously, latch 9 heads reset again and insert in the prelocalization insurance hole 1a, big dead bolt 1 is fixed on door opening state, whenever needs big dead bolt 1 work and insurance, by arbitrarily control automatically.
The effect of movable plate 10 is with helping the positioning action of big dead bolt 1 and little dead bolt 18, as long as after door opened, do not need the time spent of doing of locking to use; Big dead bolt 1 is being under idle state, when needing little dead bolt 18 to open and close lock, gos out and can draw guide 14 to open the door, and entering needs open the door with key 193, is moved plate 10 location situations at big dead bolt 1, and little dead bolt 18 can be unaffected and work on.
The characteristics of maximum of the present invention, tapered end key adopt rotating axial cylinder hole pellet shot from a slingshot, preferably adopt eight pairs of pellets shot from a slingshot, and mutual opening rate is extremely low, and safety structure is rationally distributed, and are compact effective, break through conventional design, and this product safety automatic door lock aims at numerous common people's design.Conventional key-cut is simpler and easy, easily by the lawless person special gap, and this product of design has overcome the easily defective of preparation of conventional key, for users use relievedly on lockset, has guaranteed user's the sense of security.
Most preferred embodiment of the present invention is illustrated, and various variations or the remodeling made by those of ordinary skills can not depart from the scope of the present invention.
