Description
Technical field
The utility model relates to a kind of security door automatic locking, particularly a kind ofly security door automatic locking dead bolt is stretched out the improvement on opportunity reaches control device.
Background technology
Along with China's rapid economy development, resident's living standard and habitat condition be improved significantly, antitheft consciousness and antitheft requirement improve constantly.For theftproof performance and the unlatching performance that improves security door, manufacturer is except increasing the pick-proof structure at doorframe and door leaf, security door generally adopts unblanks easily, lock conveniently, the security door automatic locking that the pick-proof performance is good, it has a plurality of dead bolts and a spring contact, at closing time, door leaf is incorporated into doorframe, spring contact touching doorframe, triggering sheet on spring contact and feeler lever retraction and the extruding unlocking mechanism double-action plate, the unlocking mechanism double-action plate is rotated around pin joint, after turning an angle, unblank hook and fixed block disengaging on the unlocking mechanism double-action plate, dead bolt, spring contact and dead bolt support eject under the promotion of thrust spring automatically, because this fashion misalignment doorframe lockhole, so dead bolt percussion doorframe can send loud hitting sound, when continuing to close door leaf, the dead bolt doorframe of will swiping is wiped the paint on the doorframe off, and dead bolt also can the scratch doorframe when serious.Though the security door automatic locking that prevents dead bolt scraping sash structure is also arranged in the market, exists weak points such as complex structure, quality of fit requirement height, difficulty of processing are big, cost of production height.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but so far solution are not preferably arranged as yet.
Summary of the invention
For overcoming existing existing the problems referred to above of security door automatic locking, the purpose of this utility model provide a kind of simple and reasonable, assembling is easy, flexible operation, working stability are reliable, closing the door delays the security door automatic locking noise reduction that dead bolt ejects automatically and protect the frame control device.
The utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises lock housing, dead bolt, the dead bolt support, spring contact, thrust spring, the unlocking mechanism double-action plate, dead bolt and spring contact are arranged on the dead bolt support, the unlocking mechanism double-action plate is hinged on the dead bolt support, lock housing is provided with fixed block, the hook of unblanking on the unlocking mechanism double-action plate matches with fixed block, feeler lever on the spring contact is corresponding with the triggering sheet on the unlocking mechanism double-action plate, be hinged with the transition plate of unblanking on the described dead bolt support, the transition plate of unblanking is provided with the inclined hook that matches with fixed block, unblank also to be provided with the brace that is enclosed within on the feeler lever on the transition plate, the feeler lever between brace and dead bolt support is arranged with stage clip.
The described transition plate of unblanking is arranged between dead bolt support and the unlocking mechanism double-action plate.
After adopting said structure, following advantage and effect are compared with prior art arranged: owing to be hinged with the transition plate of unblanking at the dead bolt support, the transition plate of unblanking is provided with the inclined hook that matches with fixed block and is enclosed within brace on the feeler lever, the transition plate of unblanking at closing time delays dead bolt and ejects, have only when spring contact is aimed at the doorframe lockhole, dead bolt just ejects automatically and locks, thereby solve the problem of dead bolt percussion and scraping noise that doorframe brings and damage, simple in structure, flexible operation light, working stability is reliable, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model before locking.
Fig. 2 is the structural representation of the utility model after locking.
1 lock housing wherein, 2 dead bolts, 3 stage clips, 4 feeler levers, 5 spring contacts, 6 thrust springs, 7 braces, 8 trigger sheets, 9 dead bolt supports, 10 transition plates of unblanking, 11 fixed blocks, 12 hooks of unblanking, 13 inclined hooks, 14 unlocking mechanism double-action plates.
The specific embodiment
Illustrated in figures 1 and 2, the specific embodiments of protecting the frame control device for a kind of security door automatic locking of the utility model noise reduction, it comprises lock housing 1, dead bolt 2, dead bolt support 9, spring contact 5, thrust spring 6, unlocking mechanism double-action plate 14, dead bolt 2 and spring contact 5 are arranged on the dead bolt support 9, unlocking mechanism double-action plate 14 is hinged on the dead bolt support 9, lock housing 1 is provided with fixed block 11, the hook 12 of unblanking on the unlocking mechanism double-action plate 14 matches with fixed block 11, feeler lever 4 on the spring contact 5 is corresponding with the triggering sheet 8 on the unlocking mechanism double-action plate 14, be hinged with the transition plate 10 of unblanking on the described dead bolt support 9, the transition plate 10 of unblanking is provided with the inclined hook 13 that matches with fixed block 11, unblank also to be provided with the brace 7 that is enclosed within on the feeler lever 4 on the transition plate 10, feeler lever 4 between brace 7 and dead bolt support 9 is arranged with stage clip 3, and the elastic force on the spring contact 5 is greater than stage clip 3 elastic force.The described transition plate 10 of unblanking is arranged between dead bolt support 9 and the unlocking mechanism double-action plate 14.
The utility model work is as follows: before locking, the hook 12 of unblanking of unlocking mechanism double-action plate 14 hooks fixed block 11, and the inclined hook 13 of the transition plate 10 of unblanking is also hanging on the fixed block 11 under the effect of stage clip 3 all the time.When spring contact 5 touching doorframes are laid the key under the door, triggering sheet 8 on spring contact 5 and feeler lever 4 retractions and the extruding unlocking mechanism double-action plate 14, make the pin joint rotation of unlocking mechanism double-action plate 14 on dead bolt support 9, after turning an angle, the hook 12 of unblanking on the unlocking mechanism double-action plate 14 breaks away from fixed block 11, before misalignment doorframe lockhole still, the inclined hook 13 that is hinged on the transition plate 10 of unblanking on the dead bolt support 9 equally hangs on the fixed block 11 under stage clip 3 elastic force effects all the time, makes the dead bolt 2 still can not release; When continuing the door leaf that closes, when spring contact 5 is aimed at the doorframe lockhole, spring contact 5 compresses power and eliminates, spring contact 5 and feeler lever 4 overcome and drive the transition plate 10 of unblanking behind the elastic force of stage clip 3 and revolve partially, inclined hook 13 on the transition plate 10 of unblanking is separated with fixed block 11, dead bolt 2, spring contact 5 and dead bolt support 9 eject under the promotion of thrust spring 6 and put in lockhole, realize automatically locking, thus the problem of the noise that solution dead bolt percussion doorframe sends and scraping doorframe damage paint.
The above; being an embodiment of the present utility model, is not that the utility model is made any pro forma restriction, is not breaking away from the technical solution of the utility model basis; the simple modification of having done, equivalent variations or modification all fall into protection domain of the present utility model.
