Description
Technical field:
The utility model relates to the theftproof lock of a kind of rotating lock tongue and band rotating lock tongue.
Background technology:
Existing dead bolt roughly divides oblique dead bolt, Square lock bolt.More than two kinds of dead bolts when locking in the mode of straight cutting with door leaf and doorframe locking.Adopt the lock mode of straight cutting, the pick-proof performance of dead bolt is undesirable.Thereby make that the pick-proof performance of theftproof lock is also undesirable.
Summary of the invention:
At above deficiency, the inventor has proposed a kind of the have rotating lock tongue of good pick-proof performance and the theftproof lock of band rotating lock tongue.
Rotating lock tongue of the present utility model comprises: outer tongue and commentaries on classics tongue, and outer tongue is connected with pushing mechanism with commentaries on classics tongue synchronization telescope, outer tongue or commentaries on classics tongue; Change tongue and be provided with the commentaries on classics tongue axle that can insert in the outer tongue, the rotating mechanism that matches with commentaries on classics tongue axle drives commentaries on classics tongue axle and rotates in the tongue outside.
In the utility model, described rotating mechanism comprises: change the tongue axle and be provided with lead, be located in the guide with the corresponding bending gathering sill of lead, guide positions is in lock housing; Described pushing mechanism is the dead bolt connecting plate that links to each other with outer tongue.Certain rotating mechanism of the present utility model also can be: guide is provided with lead, and being located at the corresponding bending gathering sill of lead changes in the tongue axle, and guide positions is in lock housing; Described pushing mechanism is the dead bolt connecting plate that links to each other with outer tongue.Adopt above rotating mechanism, making changes tongue spin locking doorframe, has improved the pick-proof performance of rotating lock tongue.Certain rotating mechanism of the present utility model and pushing mechanism also can adopt other form of structure.
The rotating lock tongue course of work of the present utility model is as follows: when tongue and commentaries on classics tongue stretch out synchronously outside the dead bolt connecting plate drives, the lead that changes on the tongue axle moves along guide groove, owing to be provided with bending in the guide groove, lead moves to bending part and just drives the rotation of commentaries on classics tongue, making changes tongue spin locking doorframe, thereby has improved the pick-proof performance of rotating lock tongue.When tongue outside the drive of dead bolt connecting plate bounces back synchronously with the commentaries on classics tongue,, drive outer tongue simultaneously and contract with the commentaries on classics gyrus lingulais because the effect of the bending in the guide groove makes the commentaries on classics tongue hold than length and resets earlier.
The theftproof lock of the utility model band rotating lock tongue comprises: the lock core in the lock housing drives dead bolt connecting plate and each dead bolt by moving part, is provided with and the corresponding guide groove of dead bolt connecting plate upper guide post in the multidirectional locking bar in the lock housing, and the dead bolt connecting plate is provided with main spring.Described dead bolt connecting plate is provided with rotating lock tongue and collision tongue; Rotating lock tongue comprises: outer tongue and commentaries on classics tongue, and outer tongue and commentaries on classics tongue synchronization telescope, outer tongue links to each other with the dead bolt connecting plate; Change tongue and be provided with the commentaries on classics tongue axle that can insert in the outer tongue, change the tongue axle and rotate in the tongue outside, change the tongue axle and be provided with lead, be provided with in the guide and the corresponding bending gathering sill of lead, guide positions is in lock housing.The dead bolt connecting plate is provided with and collides the touching hook that tongue matches, and is fixed in the lock housing with the corresponding connecting plate axis of guide of touching hook.Because theftproof lock of the present utility model has rotating lock tongue, makes theftproof lock have better pick-proof performance.
In the theftproof lock of the utility model band rotating lock tongue, described moving part comprises: be located at the cam on the lock core, and the tooth plate that matches with cam, tooth plate can drive the dead bolt connecting plate, is provided with the handle dial axis in the lock housing, and the handle dial axis can drive tooth plate.Theftproof lock of the present utility model is unblanked at indoor employing handle at outdoor employing key unlocking.
In the theftproof lock that the utility model rotating lock tongue is made, described theftproof lock also is provided with location-plate, and the driving lever that matches with cam can be stirred location-plate and move to dead bolt connecting plate rear portion.Make theftproof lock of the present utility model have stopping function.
The theftproof lock course of work of the present utility model is as follows: when unblanking, key drives the lock core cam, cam driven driving lever and tooth plate, and driving lever drives location-plate and moves (making location-plate withdraw from dead bolt connecting plate rear portion); Tooth plate drives the dead bolt connecting plate, and the dead bolt connecting plate drives collision tongue, rotating lock tongue and multidirectional locking bar retraction.When touching hook arrived the connecting plate axis of guide, the axis of guide was finished the process of unblanking with touching hook and dead bolt connecting plate location.When locking, the collision tongue touches doorframe, makes touching hook break away from the connecting plate axis of guide, and under the effect of dead bolt connecting plate main spring, rotating lock tongue, collision tongue, multidirectional locking bar stretch out the process of locking of finishing simultaneously.Wherein, the course of work of rotating lock tongue as previously mentioned.
