Description
Technical field
The present invention relates to a kind of interlocking safety mechanism for anti-theft door.
Background technology
Traditional safe-guard door lock all is on the door body door lock to be set, and being matched by the lockhole of diverse location on the dead bolt of door lock control and locking bar and the doorframe closes locking action.This known latch-up structure, its theftproof performance is imperfection also, lacks certain insurance means, and the lawless person can also unblank by some technical or destructive means.
Summary of the invention
For the theftproof performance that overcomes common safe-guard door lock fixed structure in the prior art a little less than, lack effective insurance means, prevent the problem of technical or destructive measure deficiency of unblanking, the invention provides a kind of interlocking safety mechanism for anti-theft door, this interlocking safety mechanism for anti-theft door simple in structure, open and close flexibly, reliability is high, theftproof performance is strong.
The technical solution adopted for the present invention to solve the technical problems is: comprise a body and doorframe, be provided with door lock in the door body, door lock interlocking lock rod, lock rod one side interlock swing arm in the door body, the hinged locking bar in the end of swing arm, locking bar, the lock rod is parallel to each other sealed with the movable grafting of doorframe, the bottom of locking bar is provided with the insurance jack, the insurance jack matches with an end of night bolt in the doorframe, night bolt is provided with back-moving spring, and its other end is by switching piece and the interlock of lock rod, the latch locking hook of hinged band reduction torsion spring in doorframe, one end of latch locking hook top is relative with locking bar, and other end gib head portion matches with lock slots on the night bolt.
The switching piece is the fan-shaped switching piece that is hinged in the doorframe, switching piece and night bolt twisting, and the lock rod is pressed to walk around and is connect piece.
Lock an excellent side by hinge switching piece interlock swing arm, be provided with in the hinge switching piece press down the mating face and on carry the mating face, press down the mating face and on carry the mating face respectively with the lock rod in press down end face, on carry end face and match the hinged swing arm of bearing pin in the hinge switching piece.
The present invention has strengthened the theftproof performance of security door by above-mentioned specific design, and safety factor improves greatly, has advantage simple in structure, that switching is flexible, reliability is high, theftproof performance is strong.
Description of drawings
Below in conjunction with drawings and Examples the detailed content that this is real is described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of hinge switching piece;
Fig. 3 is the structural representation of lock rod.
The specific embodiment
As shown in the figure, the present invention includes a body 1 and doorframe 2, be provided with door lock 3 in the door body 1, door lock 3 blocking lock rods 4, lock rod 4 one sides interlock swing arm 5 in the door body 1, the hinged locking bar 6 in the end of swing arm 5, locking bar 6, lock rod 4 is parallel to each other sealed with doorframe 2 movable grafting, the bottom of locking bar 6 is provided with insurance jack 7, and insurance jack 7 matches with an end of night bolt 8 in the doorframe 2, and night bolt 8 is provided with back-moving spring 9, its other end is by switching piece 10 and 4 interlocks of lock rod, switching piece 10 is the fan-shaped switching piece that is hinged in the doorframe 2, switching piece 10 and night bolt 8 twistings, and lock excellent 4 is pressed to walk around and is connect piece 10.Realize interlock by hinge switching piece 15 between lock rod 4 and the swing arm 5, be provided with in the hinge switching piece 15 press down mating face 16 and on carry mating face 17, press down mating face 16 and on carry mating face 17 respectively with lock rod 4 in press down end face 18, on carry end face 19 and match.Bearing pin 20 hinged swing arms 5 in the hinge switching piece 15, above-mentioned articulated structure can be to form a kind of card fork in swing arm 5 ends, and fork-join is on bearing pin 20.The latch locking hook 12 of hinged band reduction torsion spring 11 in doorframe 2, an end of latch locking hook 12 top is relative with locking bar 6, and other end gib head portion 13 matches with lock slots 14 on the night bolt 8.When locking a door, rotating door lock 3 glides lock rod 4, in the process that lock rod 4 glides, the mating face 16 that presses down that presses down end face 18 switching of the hinge in being hinged on doorframe 2 earlier piece 15 in the lock rod 4 has applied certain pressure, hinge switching piece 15 rotates, and making swing arm 5 around a spot wobble by the bearing pin 20 on the hinge switching piece 15, the locking bar 6 that is hinged on swing arm 5 ends enters locking in the doorframe 2, and the tail end of pushing down latch locking hook 12 lifts gib head portion 13.After this, lock rod 4 continues to glide and the fan-shaped switching piece 10 of roof pressure, hinged fan-shaped switching piece 10 rotates and overcomes the resistance propelling night bolt 8 of back-moving spring 9, the front end of night bolt 8 inserts in the insurance jack 7 of locking bar 6 bottoms setting, at this moment, night bolt 8 lockings, the lock slots 14 on the night bolt 8 is just in time relative with the gib head portion 13 of latch locking hook 12, lock rod 4 also locks with doorframe 2, and block action is finished.When unblanking, lock rod 4 is risen backward rotation door lock 3 and doorframe 2 breaks away from, at this moment, night bolt 8 and fan-shaped switching piece 10 reset under the effect of back-moving spring 9, the locking relation of insurance jack 7 is removed in night bolt 8 and the locking bar 6, lock rod 4 continues to rise, carry on the lock rod 4 hinge of end face 19 to being hinged on doorframe 2 in transfer piece 15 on carry mating face 17 and applied certain pressure, hinge switching piece 15 backward rotation, and make swing arm 5 around the fulcrum backswing by the bearing pin 20 on the hinge switching piece 15, the locking bar 6 that is hinged on swing arm 5 ends has also broken away from doorframe 2, and door lock is opened.When destructive unlocking condition occurring, locking bar 6 will certainly rise slightly, at this moment, under the effect of reduction torsion spring 11, the lock slots 14 on the night bolt 8 is hooked in the gib head portion 13 of latch locking hook 12, and night bolt 8 can not move, and the lock-out state of maintenance and locking bar 6.
