Description

Door lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of door lock.

Background technology

Door lock kind on market is very many, but their locking function structure divides three kinds of modes substantially: a kind of Dou of the being tongue side's of adding tongue " inserting bolt type ", another kind is to fix the Dou tongue with insurance to make it immobile " hard safety type ", and another fixes handle with insurance and the Dou tongue can also activity " soft safety type ".Heteroid lock should be applicable to different places, but a lot of people do not know how to divide and select for use in the big world of lock, the door lock of " inserting bolt type " is that " plug " that causes few " Dou tongue " and a square tongue and so on is combined into a firm door lock in fact, its complex structure, the cost height is useful for external door.But the interior door of suite is generally selected more succinct single Dou flapper lock for use, is exactly " hard safety type " and " soft safety type " usually, and so-called " hard safety type " then is after safety lock is opened, and insurance is with the dead bolt locking, and dead bolt just can not move; These two kinds of door locks all also exist different defectives, people are in case have different situation generations having locked " insurance " because of carelessness when door is being opened, as: door has been shut by wind, so, the Dou tongue of the lock of " hard safety type " will bump with doorframe, just is easy to a lock or door and breaks.

Summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of easy to operate, dead bolt retractable, can not cause the door lock of damage to doorframe.

For achieving the above object, the utility model provides following technical scheme: a kind of door lock, include housing, be arranged on the dead bolt on the housing, unblank follower and lock piece, described dead bolt and unblank to be connected by swing component between the follower, described dead bolt and housing are that slippage is flexible to be cooperated, one end of described lock piece and swing component are conflicted, the other end and housing pivot dress, and and housing between be provided with quick return unit, described lock piece and dead bolt are multistation and are linked, and lock piece closes with touching of dead bolt and separates the flexible cooperation of the slippage that constitutes dead bolt.

Dead bolt and housing are that slippage is flexible to be cooperated in this, one end of described lock piece and swing component are conflicted, the other end and housing pivot dress, and and housing between be provided with quick return unit, described lock piece and dead bolt are multistation and are linked, and lock piece closes with touching of dead bolt and separates the flexible cooperation of the slippage that constitutes dead bolt.The back lock piece is set like this can only be pinned the follower of unblanking, dead bolt can stretch under the situation arbitrarily freely, does not influence whole locking simultaneously, can prevent that lock piece from entering lockup state after, dead bolt is revealed in outside the housing always, thereby causes the damage to doorframe.

It is an axis of rotation that the utility model further is set to described lock piece, axis of rotation is provided with extension block, the top of extension block and swing component are conflicted, the extension block of described axis of rotation is provided with block, dead bolt be provided with on the extension block that extends to axis of rotation and with extension block on block be and compress the press block that cooperates, described quick return unit is a torsionspring.

Lock piece is an axis of rotation in this, and axis of rotation is provided with extension block, and the top of extension block and swing component are conflicted, and lock piece is set so just can be by extension block and compressing of swing component and with its pinning, simple in structure and compact; The extension block of axis of rotation is provided with block, dead bolt be provided with on the extension block that extends to axis of rotation and with extension block on block be and compress the press block that cooperates, block here and extension block are the STATEMENT OF FEDERALLY SPONSORED of dead bolt and lock piece, make it easy to operate, and described quick return unit is a torsionspring.

The utility model further is set to: the conflict end of extension block is the inclined-plane on described swing component and the axis of rotation, described torsionspring is the triangle bending, have three strong points, wherein two strong points and housing and lock piece socket, another strong point is a moving point.

In this on swing component and the axis of rotation conflict end of extension block be the inclined-plane, being provided with like this is for the conflict compact conformation between the extension block that makes swing component and axis of rotation; Torsionspring is the triangle bending, has three strong points, wherein two strong points and housing and lock piece socket, and another strong point is a moving point, the restoring force that is provided with for torsionspring can be bigger like this, can guarantee the returning quickly of lock piece.

The utility model further is set to: the place, working end that described housing is positioned at dead bolt is provided with box body, be arranged with back-moving spring on the working end of dead bolt, and in interspersed and this box body, an end of described back-moving spring and dead bolt are conflicted, and the other end and inboard wall of cartridge are conflicted.

The place, working end that this middle shell is positioned at dead bolt is provided with box body, is arranged with back-moving spring on the working end of dead bolt, and in interspersed and this box body, an end of described back-moving spring and dead bolt are conflicted, and the other end and inboard wall of cartridge are conflicted.What be provided with like this then is in order to impel dead bolt can be returned to original position fast.

Below in conjunction with accompanying drawing the utility model is further described:
