Description

A kind of stealthy door lock

Technical field

The utility model belongs to lock technology field, especially relates to a kind of stealthy door lock.

Background technology

Along with improving constantly of living standard, people are also increasingly high to the requirement of interior decoration, particularly repair the coordination of style for integral installation, usually can not hope that promptly it resembles door in appearance at the stealthy door of indoor use, but with body of wall one integrated mass on every side.What at present, hinder this effect mainly is door lock and handle.

Existing lockset generally comprises lock body, Button Block and the assembly of unblanking, and wherein Button Block is installed on the doorframe, and lock body is installed on the door leaf with the assembly of unblanking, and the assembly control dead bolt motion of unblanking can doublely be done handle simultaneously.Obviously, such lockset be do not have concealed.On the other hand, existing dead bolt mainly leans on elastic force or machine driving to realize and the fastening of Button Block that under door opening state, dead bolt is exposed to outer, does not have disguise equally.These problems not only influence the attractive in appearance of door, also easily children are waited and cause personal injury.

The utility model content

The utility model purpose provides the stealthy preferably door lock of a kind of disguise.

For this reason, the utility model has adopted following technical scheme: a kind of stealthy door lock comprises the lock body that is fixedly installed on the door leaf and the assembly of unblanking; And be fixedly installed in the Button Block on the doorframe; It is characterized in that: the described assembly of unblanking comprises a ring washer, a part of hollow out of back-up ring, and pivot is equipped with a pressing piece on the ring washer; Its pivot is parallel to the door leaf plane, thereby pressing piece can partly stretch into the openwork part of ring washer around this pivot rotation; Have connector on the lock body, the one of which end stretches in the ring washer, and matches with pressing piece.

Further, the ring washer inboard also has a back-moving spring, props up the inboard of pressing piece.

In the described pressing piece, stretch out the part of ring washer during rotation, its end is provided with handle portion.

The assembly of unblanking also comprises a fixture, is installed in the ring washer inboard, fixedly the position of pressing piece pivot and back-moving spring.

The assembly of unblanking of the utility model is installed on the door leaf, during use pressing piece is inwardly pressed, and pressing piece promptly rotates around pivot, and a part stretches in the ring washer, and a part is stretched out outside the ring washer; Stretch into the connector that the part promotion in the ring washer links to each other with lock body, thereby make the dead bolt withdrawal unblank, stretch out the outer part of ring washer because end has handle portion, the user holds this handle portion and can or push open Men Lakai.When the action of opening the door finishes, the user unclamps pressing piece, and then back-moving spring promotes pressing piece and does reverse rotation, and the part of stretching out ring washer up to pressing piece just now is repositioned to the not openwork part that touch ring washer, thereby restPoses.

Can see that from above description the pressing piece of the utility model is on original state, and is parallel with ring washer, door leaf, so when installing, the assembly of unblanking can flush with door leaf, has no ledge, has good disguise.

In order to let the side of door leaf that good disguise is also arranged, the lock body of the utility model, Button Block can adopt following technical scheme:

Have a dead bolt in the lock body, match, be articulated in the lock body through the dead bolt installation shaft with described connector; Dead bolt has the first dead bolt magnetic patch and the second dead bolt magnetic patch respectively at the two ends of dead bolt installation shaft, Button Block has the first Button Block magnetic patch and the second Button Block magnetic patch respectively in the corresponding position; Wherein the first dead bolt magnetic patch is made as heteropole with the first Button Block magnetic patch and inhales mutually, and the second dead bolt magnetic patch and the second Button Block magnetic patch are made as homopolar-repulsion.

The center of gravity of dead bolt is below the dead bolt installation shaft, and its distance and dead bolt installation shaft with the dead bolt edge is identical apart from the distance at dead bolt edge.

Also can establish an insurance institution on the lock body, insurance institution comprises an insurance shifting block, is rotatably installed in the lock body; The insurance shifting block have one with the inconsistent turned position of dead bolt.

More specifically, described insurance shifting block has one and rotates an end and a jag, rotates end and is installed in the shifting block groove of lock body, and jag stretches out outside the shifting block groove; The shifting block groove has the turned position of a trumpet-shaped opening with restriction insurance shifting block.When the insurance shifting block is in free position, do not influence the motion of dead bolt; When the insurance shifting block forwarded the locking position to, its jag propped up the dead bolt of locking, makes it can not rotate back into lockset position of coupler.

The utility model is when free state, and the insurance shifting block is in free position, and the assembly of unblanking flushes with door leaf; Dead bolt is freely-movable also; Under action of gravity, its center of gravity must be positioned at the dead bolt installation shaft vertically under, this moment, dead bolt all flushed with the door leaf side up and down; So door leaf has good disguise and safety.After closing door, two groups of dead bolt magnetic patch and Button Block magnetic patch generation magneticaction, wherein a pair of repelling each other, a pair ofly inhale mutually, impel the dead bolt rotation thereby form combined moment, a part gets in the Button Block on the doorframe, on door lock.This moment as the state that need keep Locked then rotate the insurance shifting block to the locking position, make dead bolt can not rotate return again; As need open the door once more, then will insure shifting block and turn to free position, press the pressing piece in the assembly of unblanking then, the part of pressing piece stretches in the ring washer, promotes connector and then promote dead bolt to rotate, and makes dead bolt leave Button Block and gets back to free state; Hold the terminal handle portion of pressing piece, can open the door.

The utility model interacts through two groups of magnetic patch, thereby has further strengthened the effect of locking of lockset, though therein the magnetic force of one or one group magnet weaken or situation about disappearing under, also can finely lock.
