Description
Technical field
The present invention relates to lockset, especially relate to safe-guard door lock.
Background technology
Present various security door; For example family expenses security door, sliding anti-theft door, safety cabinet security door or garage door etc., in order to reach anti-theft feature, it goes up theftproof lock of installing; Basic structure comprises lock core and the dead bolt group that is arranged on the door leaf periphery; Normally drive the lock core rotation by the supporting key that inserts, lock core is directly controlled the dead bolt group through various mechanical driving devices and is moved, and reaches the purpose of unlatching or locking door leaf.The mechanical driving device structure of theftproof lock is varied, and versatility is not high; Most complex structure, manufacturing cost is high; Usually unblank or directly cooperate the lock inner spring to drive the dead bolt motion realization during locking by key rotation or turn door handle; Time is long slightly; Mechanical transmission mechanism lubrication oil lubrication oil dry or dead bolt is stained with dust and can causes that dead bolt moves and block in the lock, because theftproof lock is encapsulated in the door, gives that mechanical transmission mechanism refuels difficult in the lock; And refuel very easily when people's inlet/outlet to the dead bolt in the dead bolt group, wipe and run into clothing and be difficult to clean; When retardance takes place when; The dead bolt that screw key or turn door handle could drive in the dead bolt group of must exerting oneself moves, because the volume of key own is less, is difficult for making power; Being difficult to drive dead bolt when retardance takes place moves; The situation that overexerts for a long time and very easily cause key to deform even rupture, firmly the turn door handle can't realize that also dead bolt moves, reliability is not high.
Summary of the invention
The objective of the invention is the deficiency to prior art, and a kind of novel structure, simple, manufacturing cost is lower, versatility is higher, reliability is higher safe-guard door lock are provided.
The objective of the invention is to realize through following technical scheme:
A kind of safe-guard door lock; Comprise lock core and the dead bolt group that is arranged on the door leaf periphery; Different with prior art is: the termination at lock core is provided with gear, is provided with insurance tooth bar and this gears engaged on the next door of this gear, and it is equipped that an end of said insurance tooth bar is provided with brake block and tooth bar a and tooth bar b coupling; Be provided with handle gear and its engagement between said tooth bar a and the tooth bar b, said tooth bar a is connected with the dead bolt group respectively with tooth bar b.
Described tooth bar a and tooth bar b horizontal parallel are provided with the handle gear equipped; The left end of upper rack b is connected with upper end dead bolt group with left end dead bolt group with pull bar a through pull bar c respectively with right-hand member, and the left end of following tooth bar a is connected with right-hand member dead bolt group with lower end dead bolt group with pull bar d through pull bar b respectively with right-hand member.
Described handle gear is connected with handle on being fitted in door leaf.
Dead bolt in the described dead bolt group is tack dead bolt or jag dead bolt.
Described jag dead bolt is divided into two sections; Wherein one section end portion is a cone shape, and the side of this cone shape is provided with two clamp bar slots, and another section is divided into two; An end of every is and the equipped tenon of described draw-in groove coupling that this tenon is slidingly connected with described draw-in groove respectively.
The jag dead bolt is the dead bolt that is fitted on the push-and-pull door leaf periphery, and the dead bolt hole on this dead bolt and the sliding door doorframe is equipped.
Adopt above-mentioned structure, the dead bolt group around the door leaf changes by the gear among the present invention, tooth bar to be controlled, and the present invention is when opening; After inserting lock core and reverse with its equipped key, the gear driven insurance tooth bar on the lock core termination moves, and insurance rack drives brake block breaks away from tooth bar a, b; Manually be rotatably provided in the handle that is connected with the handle gear on the door leaf this moment; Can drive the dead bolt group through tooth bar a, b and move, realize the unlatching of door lock, on the contrary locking then.The present invention is installed in the door leaf; Have only keyhole and handle hole on the door leaf, the part of protrusion door leaf when not having former theftproof lock and gate flap equipped, the door leaf external surface is an integral planar; Therefore can realize pick-proof, anti-technical opening, anti-violence and anti-cutting, anti-theft effect is preferably arranged.
The present invention can singly use, and original lock no longer is installed on the door leaf, also can combine original lockset simple in structure on the door leaf, and former lockset is only controlled the simple relatively dead bolt that itself carries, and the dead bolt group of door leaf periphery is driven by the present invention.
Because with the supporting lock core of the present invention, the effect of its key only limits to the turn lock core, and the action of pulling dead bolt is realized by the rotary handle gear; Even therefore increase service time; The lubrication oil of mechanical device is dry, and the turn key is leicht fallen D/A also, and can do greatly slightly with the equipped handle of handle gear; Turn is got up easily sensitive, and reliability is high.
The present invention can be widely used in family expenses security door, sliding anti-theft door, safety cabinet security door or garage door etc., can be singly with or with door leaf on original lockset coupling, versatility is higher.
The present invention has novel structure, simple, compares with the structure that prior art is complicated, and low cost of manufacture, versatility is higher, the reliability advantage of higher.
