Description
Technical field
The present invention relates to a kind of locksets, can realize the mute lock of bolt retraction locking automatically more particularly to one kind.
Background technique
When door and window is closed, since the inadvertent or habit of people make so, often to forget locked door and window, this is with regard to band
Some potential safety problems is carried out, door and window can be pulled open directly, and there are stolen possibility.If can be realized if door and window is finally closed certainly
Dynamic locking can undoubtedly greatly improve safety, but also only realize the closing of door and window with structures such as shutting window devices at present, also
Fail the door lock for effectively realizing automatic blocking briefly.
Yet another is exactly that for door and window when being closed, the lock tongue of lock touches locking plate, and inside retraction and then lock tongue are again
It pops up in the cavity being locked in locking plate, realizes locking.It is not difficult to find that lock tongue can be hit during door and window is closed
Locking plate issues the sound, brings noise, and if things go on like this, will lead to door and window stress generation shape due to hitting brought impact
The case where change, shifting block driving mechanism etc. are hit and damage.
Summary of the invention
The invention aims to provide a kind of mute lock, automatic blocking can be realized, improve safety, solve simultaneously
Lock tongue and locking plate the problem of contact-impact, can be avoided collision and friction of the lock tongue in opening and closing, reach quiet in open locking
Audio fruit, while improving the service life of lock.
In order to achieve the above objectives, the technical solution adopted by the present invention is that：
The present invention provides a kind of mute lock, including lock body and locking plate, the lock body includes lock box, lock tongue assembly, slide block
And handle, handle are connected with the slide block and the slide block can be driven to rotate, the slide block and the lock tongue assembly
Linkage, for driving the lock tongue assembly flexible, the locking plate has the cavity limited to lock tongue, goes back in the lock body
Equipped with fixture block, the fixture block is rotatably mounted in the lock box, and the mute lock, which has, unlocks and be latched two states,
Under the unlocking condition, the lock tongue front end is located in lock box, and the fixture block blocks the slide block；In the latch like
Under state, the lock tongue front end is prominent outside the lock box, and the fixture block is separated with the slide block, wherein described
Fixture block is used to switch between unlocking and blocking the state of the mute lock.
For above-mentioned technical proposal, there are also further optimal enforcement schemes by applicant.
Further, one end of the fixture block is to stretch out lock box under unlocking condition, the other end setting of the fixture block
There is a positioning region for the hook that can catch on slide block, under unlocking condition, the rotation of slide block is so that the lock tongue front end is located at lock box
Interior, the slide block is caught in the positioning region of the fixture block；Under blocking, one end stress of the fixture block, so that fixture block rotates
And then the positioning region of the other end of the fixture block and slide block is driven to thread off, the lock tongue front end is i.e. prominent in the lock box
Outside.
Further, the limited block for limiting the fixture block turned position is provided in the lock box.
Further, the limited block is arranged close to positioning region one end of the fixture block, for limiting under blocking
The turned position of the fixture block.
Further, the lock body is additionally provided with the locking mechanism for locking the lock tongue.
Further, the locking mechanism includes shifting block, shifting block driving mechanism and latch, the shifting block driving mechanism by
External drive movement, the shifting block are rotated with the movement of the shifting block driving mechanism, and the shifting block drives the latch fortune
Dynamic, the latch is for the locked position for limiting the lock tongue.
Further, the latch is vertically arranged on the inner wall of the lock box, and the latch is along the lock box
Inner wall vertical shift, limiting tooth is provided on the latch, the shifting block rotation contacts the limiting tooth and drives the lock
Stops movement.
Further, the limiting tooth is arranged perpendicular to the latch, including the first limiting tooth and the second limiting tooth,
The shifting block driving mechanism close to limiting tooth position be arranged, and the initial position of the shifting block be located at first limiting tooth and
Between second limiting tooth.
Further, the groove of latch insertion can be held by being provided in the bottom of the lock tongue, the groove close to
The lateral wall of the lock tongue 21 is arranged, for locked under its retracted state to lock tongue.
Further, the torsional spring for resetting fixture block is provided at the fixture block.
Since above-mentioned technical proposal is used, the present invention is provided with following advantages compared with prior art：
Mute lock of the invention, is additionally arranged rotatable fixture block, and when unlocking, rotation handle rotates slide block, and then band
Dynamic lock tongue retraction, the lower part of slide block is locked by the positioning region of fixture block after lock tongue is completely retracted, and fixture block touches when closing window
Latch buckle realizes the tripping between fixture block and slide block to the rotation that is struck, so that lock tongue is discharged, so that lock tongue pops up, from
And realize automatic blocking, it prevents people from forgetting to shut, improves safety, while lock tongue also would not be in opening and closing by collision friction
It arrives, achievees the purpose that mute.
Further, set locking mechanism can be realized the locking for lock tongue, not still after lock tongue pop-up
It is locked, the safety of lock is improved, in addition can also realize, which also can be realized after lock tongue retraction, locks lock tongue, in this case
User can be allowed there are more selections, lock tongue may be selected and do not pop up, lock in normally opened（Lock tongue does not pop up）A state, it is full
The individual demand of sufficient user, such as the door equipped with door closer can utmostly reduce the anti-of lock tongue and inner structural members
Double action is made.
