Description

Safe-guard door lock

Technical field

The utility model relates to lockset, especially relates 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 the theftproof lock of installing, basic structure comprises lock core and is arranged on the dead bolt group of door leaf periphery, normally drive the lock core rotation by the supporting key that inserts, lock core is directly controlled the dead bolt group by 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, the manufacturing cost height; Usually unblank or directly cooperate the lock inner spring to drive the dead bolt motion during locking to realize 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, give mechanical transmission mechanism oiling difficulty 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, be 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.

The utility model content

The purpose of this utility model is at the deficiencies in the 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 purpose of this utility model is to realize by 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, unlike the prior art be: the termination at lock core is provided with gear, be provided with insurance tooth bar and this gears engaged on the next door of this gear, it is equipped that one end of described 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 described tooth bar a and the tooth bar b, described 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 by 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 by 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, dead bolt group around the door leaf changes by the gear in the utility model, tooth bar to be controlled, the utility model 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 by tooth bar a, b and move, realize the unlatching of door lock, on the contrary locking then.The utility model is installed in the door leaf, have only keyhole and handle hole on the door leaf, protrude the part of 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 utility model can singly be used, original lock no longer is installed on the door leaf, also can be in conjunction with original lockset simple in structure on the door leaf, 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 utility model.

Because with the supporting lock core of the utility model, 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 handle that the handle gear is equipped with, turn is got up easily sensitive, the reliability height.

The utility model 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 utlity model has novel structure, simple, compare with the structure of prior art complexity, low cost of manufacture, versatility is higher, the reliability advantage of higher.
