Description

A kind of fast lock is opened safe-guard door lock soon

Technical field

The utility model relates to field of lockset, and especially a kind of fast lock is opened safe-guard door lock soon.

Background technology

Existing safe-guard door lock normally makes main dead bolt parts stretch out or the indentation housing under the stirring of tapered end assembly, realizes locking and unlatching to door.These safe-guard door locks all need rotate the key that cooperates with the tapered end assembly and just can make the tapered end assembly stir main dead bolt parts when locking or unlatching door, operational motion is loaded down with trivial details.

The utility model content

The utility model provides a kind of fast lock to open safe-guard door lock soon to the defective that prior art exists, and can effectively improve the efficient of unblanking, and easy to use, theftproof is strong.

For this reason; The utility model is taked following technical scheme: a kind of fast lock is opened safe-guard door lock soon; Comprise housing, be directed to and the main dead bolt parts of the housing that can stretch out or withdraw, can remove the non-return of main dead bolt parts and stir that main dead bolt parts stretch out or the lock head component of the housing of withdrawing and be coupling on housing and the two sides respectively with interior handle and outside the handle dial axis assembly that joins of handle; It is characterized in that described main dead bolt parts comprise main bolt plate; The bottom surface of main bolt plate be coupling one can main relatively bolt plate sideshake the dead bolt connecting rod; Have adjustment hole on the described main bolt plate, the dead bolt connecting rod is provided with the stop pin that passes adjustment hole, and the end face of said main bolt plate is provided with the block of the said stop pin of backstop; The shifting component of stirring stop pin is set on the described block, and this shifting component one side cooperates with lock head component, and opposite side and handle dial axis assembly match.The door lock of this structure in use can be in a conventional manner opened door lock or close through the key turns tapered end, also can indoor rotate through handle in the handle dial axis open or close door lock; Because stirring stop pin with shifting component, employing make itself and baffle plate form the structure that dislocation reaches the main dead bolt non-return of releasing, more light when utilizing the key turns tapered end to unblank, unblank rapidly flexible movements, compact conformation.

Handle dial axis and outer handle dial axis in described handle dial axis assembly comprises, both opposing ends are coupling on housing, and abutting end is linked in together each other.This structure makes inside and outside handle dial axis be positioned on the same axle center, makes that promptly the inside and outside handle on the door is positioned on the same axle center, and for door lock, its compact conformation for door, is convenient to install safe-guard door lock.

Described shifting component comprises dead bolt driving lever, cam driving lever and main driving lever, and described dead bolt shift lever axis is connected on the block, and the one of which side has the through hole of ccontaining said stop pin, and opposite side forms lead; Described main driving lever and cam driving lever are coupling each other and stack together, and described main shift lever axis is connected on the block, and its underpart has the pilot hole of ccontaining lead.Main driving lever moving belt action-oriented post motion, and make the dead bolt driving lever promote stop pin it to be formed with baffle plate misplace, at this moment, baffle plate has been removed spacing to stop pin, guarantees that main dead bolt stretches out outside the housing.

Be with outer handle shift fork on the described outer handle dial axis, and outside fan groove and the projection that cooperatively interacts be set between handle dial axis and outer handle shift fork, described outer handle shift fork and main driving lever match; Described lock head component comprises the tapered end shifting block, and described cam driving lever sidepiece forms the allocating slot that matches with the tapered end shifting block.Main driving lever and cam driving lever link each other, guarantee to rotate outer handle or rotational lock head and all can realize unblanking, and reach and open effect soon.

Handle shift fork in being with on the handle dial axis in described; And setting cooperatively interacts between interior handle dial axis and interior handle shift fork fan groove and projection; Head is housed on the described housing remains on the outer oblique tongue spare of housing, described oblique tongue spare matches with interior handle shift fork.When not receiving external force, tiltedly tongue keeps stretching out state always, and handle can make main dead bolt and tiltedly tongue indentation simultaneously in rotating, and reaches and opens effect soon.

Described main bolt plate is provided with the shoulder pole shift fork, is provided with reduction torsion spring on the shoulder pole shift fork again, and an end and the tapered end shifting block of shoulder pole shift fork match, and the other end and interior handle shift fork match.Clockwise rotate tapered end and stir the shoulder pole shift fork, the handle shift fork makes oblique tongue indentation in being stirred by the shoulder pole shift fork again.

Be nested with one on the described lead and keep the driving lever spring that main dead bolt stretches out state.

Also be provided with the safety tongue shifting block in the described housing, the sidepiece of said main dead bolt parts is provided with the safety tongue that can in housing, stretch, and the lower end of said safety tongue has with said safety tongue shifting block matches and stirs groove.Lock core can be installed in the safety tongue shifting block and just dispose corresponding key or corresponding button directly is set outside housing and link to each other, can both reach the flexible purpose of control safety tongue, the enhancing theftproof with the safety tongue shifting block.

The utility model is tool antitheft and conventional function of opening locking through tapered end with key both, can open fast or locking through handle again, and is simple to operate, simple and compact for structure, is convenient to process and assemble, and anti-theft feature property is strong.Main dead bolt employing is stirred stop pin with shifting component makes itself and baffle plate form the structure that dislocation reaches the main dead bolt non-return of releasing, more light when utilizing the key turns tapered end to unblank, and unblanks rapidly flexible movements, compact conformation.
