Description
Technical field
The utility model belongs to lock technology field, particularly a kind of big lock of automatic lock pin that is applicable on the security door.
Background technology
The existing big handle of automatic lock pin that is used on the security door is locked in use and exists the inconvenience of locking a door, and causes main dead bolt not lock easily and lose the weak point of the anti-theft feature of security door.
Summary of the invention
The utility model is at the existing existing inconvenience of locking a door of big lock of automatic lock pin that is used on the security door, and the weak point that causes main dead bolt not lock easily provides a kind of easy and simple to handle, big lock of the automatic lock pin of insurance safe in utilization.
The technical solution adopted in the utility model is finished in the following way: big lock of lock pin comprises side panel automatically, lock box, two-way oblique dead bolt, four torsion springs, sliding piece, moving block, retaining sheet, bump rotor, screens, planker, lock core, gear piece, spacer and locking closure, wherein side panel and lock box are fixed together, gear piece and lock box hinge link together, one end hinge of screens and planker links together, screens is connected with extension spring with the other end of planker, main dead bolt on the planker passes main dead bolt hole on the side panel, post on the lock box passes the kidney slot on the planker, post on the planker passes the kidney slot on gear piece and the lock box, successively with sliding piece, moving block, retaining sheet, bumping rotor is installed in the circular hole on the lock box, the other end of sliding piece is against on the protuberance on the planker, retaining sheet is against on the protuberance on the planker, spacer and spacer torsion spring hinge are on lock box, and its excess-three torsion spring is enclosed within respectively on three posts on the lock box; One end of four torsion springs all is against on the inwall of lock box, and the other end of four torsion springs is buckled in two-way oblique dead bolt respectively, bump in the afterbody Baltimore groove of rotor, planker and be against on the spacer; Two-way oblique dead bolt passes the two-way oblique dead bolt hole on the side panel, and two-way inclined lock tongue pole is by on planker, and the protuberance of afterbody is stuck in the elongated hole on the locking closure.
In the structure of big lock of above-mentioned automatic lock pin, by two-way oblique dead bolt, bump rotor, screens, planker, torsion spring and form an automatic device.At closing time, two-way oblique dead bolt is run into doorframe and is withdrawn automatically, runs into rotor, bumps rotor generation rotation and makes the other end run into screens, and screens produces rotation simultaneously, and screens is broken off relations, and at this moment dead bolt ejects automatically under the effect of torsion spring, the door automatic blocking.
In the structure of big lock of above-mentioned automatic lock pin, form a power-assisted tumbler by the gear on the lock core, gear piece and moving block, sliding piece.Fashionable at locking, press handle, drive sliding piece by moving block and rotate, make the planker translation, the dead bolt withdrawal is opened lock; Fashionable at locking, also can insert key turns, rotate by the gear driven gear piece, gear piece makes the dead bolt withdrawal by the moving planker translation of the cornice on kidney slot and the planker, and at this moment gear piece has played drive, power-assisted effect.
In the structure of big lock of above-mentioned automatic lock pin, form insurance, control device by moving block, retaining sheet, spacer and screens.After door is shut, the lock auto-closing.If handle is up lifted, at this moment drive retaining sheet and rotate by moving block, under the effect of spacer, produce self-locking, play the pick-proof effect.Closing in front of the door, earlier handle one is being lifted, closing and also produce self-locking behind the door, playing the pick-proof effect.After lock produced self-locking, handle can not be opened, and can only insert key and just can unblank.When inserting key turns, gear is stirred screens earlier, and retaining sheet is stirred in screens, under the effect of spacer, makes retaining sheet lose stopping function, and then drives the gear piece rotation, and gear piece drives the planker translation, makes the tapered end withdrawal.
Big lock of the automatic lock pin of the utility model is big phase-locked ratio with the existing automatic lock pin that is used on the security door, have easy and simple to handle, the characteristics of insurance safe in utilization.The utility model is particularly suitable as a kind of big lock of automatic lock pin that is used on the security door.
