Description
Technical field
The utility model relates to a kind of anti-theft automatic door lock, particularly a kind of damping noise-stop device that can play damping and silencing when anti-theft automatic door lock is locked.
Background technology
In order to improve the theftproof performance of security door and open performance, manufacturer except increasing except prying-resistant structure on doorframe and door leaf, theftproof lock generally adopt unblank easily, lock conveniently, anti-theft automatic door lock that pick-proof performance is good.Anti-theft automatic door lock comprises housing, up and down resiliency urged mechanism, lock body mechanism, trigger mechanism, unlocking mechanism, the planker of lock body mechanism is fixed with multiple dead bolt, trigger mechanism is automatic locking by the dead bolt in upper and lower resiliency urged mechanism controls lock body mechanism, and the dead bolt that unlocking mechanism is controlled in lock body mechanism by the planker of lock body mechanism is unblanked.Closing the door in automatic locking process, the triggering tapered end touching doorframe of trigger mechanism, dead bolt in lock body mechanism is automatic spring under upper and lower resiliency urged mechanism resiliency urged, because now dead bolt not yet aims at doorframe lockhole, therefore dead bolt collision doorframe will produce and shakes and send loud hitting sound, and when continuing to close door leaf, dead bolt will be swiped doorframe, wipe the paint on doorframe off, time serious, dead bolt also can scratch doorframe.Although also there is the anti-theft automatic door lock preventing dead bolt scraping sash structure in the market, there is the weak points such as complex structure, quality of fit requirement is high, difficulty of processing is large, cost of production is high.For this reason, many manufacturers and knowledgeable people are studied for the problems referred to above and develop, but not yet have desirable product commercially to emerge so far.
Summary of the invention
For overcoming the problems referred to above existing for existing anti-theft automatic door lock, the purpose of this utility model be to provide a kind of simple and reasonable, assemble easy, flexible operation is light, it is little to shake, noise is low, working stability reliable anti-theft automatic door lock damping noise-stop device.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises housing, upper and lower resiliency urged mechanism, lock body mechanism, trigger mechanism, unlocking mechanism, the planker of lock body mechanism is fixed with dead bolt, trigger mechanism is automatic locking by the dead bolt in upper and lower resiliency urged mechanism controls lock body mechanism, the dead bolt that unlocking mechanism is controlled in lock body mechanism by the planker of lock body mechanism is unblanked, the planker of described lock body mechanism is fixed with damping mechanism, damping mechanism comprises damper, securing cover plate, fixed head, fixed head is fixed on the planker of lock body mechanism, damper is arranged on fixed head by securing cover plate, the damping masthead of damper is pressed on the housing of panel side.
Further scheme of the present utility model, described damper comprises damper rod, damping body, is provided with damping spring and hydraulic oil in the hydraulic cavities of damping body, and damper rod to be arranged in hydraulic cavities by sealing ring and to match with damping spring.
Further scheme of the present utility model, is provided with cover plate in being sealed and matched with damper rod in the hydraulic cavities of described damping body.
After adopting said structure, compared with prior art have the following advantages and effect: one is because damper is arranged on fixed head by securing cover plate, the damping masthead of damper is pressed on the housing of panel side, when laying the key under the door, damper rod produces damping force from small to large under the effect of damping spring, this damping force delays dead bolt in lock body mechanism and ejects speed, thus solve dead bolt percussion and scraping doorframe bring the problem of vibrations, noise and damage.Two is that damper produces boosting power from big to small under the effect of damping spring, and this boosting power makes unlock operation light more flexibly when unlocking mechanism is unblanked by the planker dead bolt controlled in lock body mechanism of lock body mechanism.

Wherein 1 housing, about 2 resiliency urged mechanisms, 3 lock body mechanism, 4 trigger mechanisms, 5 dead bolts, 6 unlocking mechanisms, 7 dampers, 8 damping mechanisms, 9 damper rods, 10 damping bodys, cover plate in 11,12 sealing rings, 13 damping springs, 14 securing cover plates, 15 fixed heads.
Detailed description of the invention
Fig. 1, shown in Fig. 2 and Fig. 3, for the specific embodiments of a kind of anti-theft automatic door lock damping of the utility model noise-stop device, it comprises housing 1, upper and lower resiliency urged mechanism 2, lock body mechanism 3, trigger mechanism 4, unlocking mechanism 6, the planker of lock body mechanism 3 is fixed with dead bolt 5, the dead bolt 5 that trigger mechanism 4 is controlled in lock body mechanism 3 by upper and lower resiliency urged mechanism 2 is automatic locking, the dead bolt 5 that unlocking mechanism 6 is controlled in lock body mechanism 3 by the planker of lock body mechanism 3 is unblanked, the planker of described lock body mechanism 3 is fixed with damping mechanism 8, damping mechanism 8 comprises damper 7, securing cover plate 14, fixed head 15, fixed head 15 is fixed on the planker of lock body mechanism 3, damper 7 is arranged on fixed head 15 by securing cover plate 14, damper rod 9 top of damper 7 is pressed on the housing 1 of panel side.
Described damper 7 comprises damper rod 9, damping body 10, is provided with damping spring 13 and hydraulic oil in the hydraulic cavities of damping body 10, and damper rod 9 to be arranged in hydraulic cavities by sealing ring 12 and to match with damping spring 13.In order to ensure the stability that damper rod 9 works, in the hydraulic cavities of described damping body 10, be provided with cover plate 11 in being sealed and matched with damper rod 9.
Utility model works is as follows: when locking, doorframe touched by trigger mechanism 4, trigger mechanism 4 makes the interlocking of lock body mechanism 3 be separated, dead bolt 5 in lock body mechanism 3 is locked under upper and lower resiliency urged mechanism 2 promotes, lock body mechanism 3 is with fluctuation dampers which 7 to work simultaneously, damper rod 9 produces damping force from small to large under the effect of damping spring 13, damping spring 13 in course of action gradually by elasticity of compression energy, the dead bolt 5 that this damping force delays in lock body mechanism 3 ejects speed, realize automatic locking, solve dead bolt 5 percussion and scraping vibrations that doorframe brings in process of locking simultaneously, the problem of noise and damage.
When unblanking, unlocking mechanism 6 drives lock body mechanism 3 to work after the elastic thrust overcoming upper and lower resiliency urged mechanism 2, the elasticity of compression now on damper 7 can discharge simultaneously, the boosting power that damper rod 9 produces from big to small under the effect of damping spring 13 promotes lock body mechanism 3, accelerate the retraction speed of dead bolt 5, make the process of unblanking light more flexibly.
The above; just an embodiment of the present utility model, not makes any pro forma restriction to the utility model, is not departing from the technical solution of the utility model basis; done simple modification, equivalent variations or modification, all fall into protection domain of the present utility model.
