Description
Technical field
The present invention relates to a kind of door closer or shutting window device, especially a kind of door closer or shutting window device unlock dynamics adjust knot
Structure.
Background technology
Chinese patent literature CN107724838A disclosed a kind of chute-type automatic window closing device on 2 23rd, 2018, packet
Include the rocking arm that device ontology, positioning seat, both ends are connect with device ontology and positioning seat phase pivot respectively.Device ontology includes sliding slot, is set to
It is used for the locking mechanism of rocking arm locking opposite with device ontology and in sliding slot for driving rocking arm slidably with respect to device ontology
The unlocking mechanism that window is closed.Unlocking mechanism include setting locating rack on the chute, can be flexibly connected with locating rack and
Unlock frame, elastic component and the warming glass marble extended along track length direction.When a fire, warming glass marble is with room
Interior temperature rise and it is quick-fried broken, elastic component, which restores deformation, to be pushed to locking mechanism by unlock frame and makes locking mechanism unlock.It should
The elastic component elastic force for being connected to locating rack in structure in locking mechanism and unlocking between frame is fixed, so, unlocking mechanism
Unlock dynamics is also required to meet the elastic force requirement of elastic component；But since unlocking mechanism and locking mechanism are independent from each other, solution
The unlock dynamics of latch mechanism can not necessarily meet the unlocking requirements of locking mechanism.
Invention content
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and provide a kind of simple and reasonable, suitable
Close a variety of unlocking mechanisms, door closer easy for installation or shutting window device unlock dynamics adjustment structure.
The object of the present invention is achieved like this：
A kind of door closer or shutting window device unlock dynamics adjustment structure, including sliding rail, slide block assembly and stop determine device, slide block assembly cunning
It is dynamic to be arranged in sliding rail, stop determining device to include that fixed seat, rocking bar, unlock slide and elastic component, the fixed seat are fixed at
In sliding rail, the rocking bar, which is swung, to be arranged in fixed seat, and rocking bar one end is equipped with the latch hook for coordinating with slide block assembly, and rocking bar is another
One end and the unlock slide inclined-plane coordinate, and the unlock slide is arranged in sliding rail, the elastic component be arranged in fixed seat and
Between unlock slide；It is characterized in that：The elastic component at least one end is equipped with guide screw movement regulating part, elastic component and guide screw movement
Regulating part is coaxially disposed, and changes the elastic force of elastic component by guide screw movement regulating part.
The purpose of the present invention can also use following technical measures to solve：
As a more specific scheme, the elastic component is compressed spring, and the fixed seat is equipped with through the logical of its rear and front end
Hole, the guide screw movement regulating part are chock plug, and chock plug coordinates with through hole whorl, and unlock slide, pressure are directed toward in one end of compressed spring
The other end of contracting spring is connected to chock plug inner end.
As further embodiment, the chock plug outer end is equipped with regulating tank.Regulating tank is used to coordinate with tool, to turn plug
Head, to adjust the compressive state of compressed spring.
As further embodiment, temp.-controlled glass tube, unlock slide court are additionally provided between the fixed seat and unlock slide
It is equipped with location hole to one end of fixed seat, temp.-controlled glass tube one end and location hole are mating, the temp.-controlled glass tube other end and pressure
Contracting spring one end abuts.When temp.-controlled glass tube bursts, compressed spring changes to the active force of fixed seat and unlock slide
Or it losing so that rocking bar is in relaxed state, and slide block assembly is detached from the latch hook of rocking bar under the active force of door closer or shutting window device,
To realize automatic door-closing/window.
As further embodiment, it is packaged with thermo-responsive medium in the temp.-controlled glass tube, in temp.-controlled glass tube one end
The heart is equipped with positioning protrusion, and the temp.-controlled glass tube other end is spherical round end；The location hole of positioning protrusion and unlock slide is mating；
Spherical round end is abutted with compressed spring one end.Thermo-responsive medium is more sensitive to temperature change, when such as encountering fire, thermo-responsive Jie
Matter temperature is increased and is expanded so that temp.-controlled glass tube bursts.Temp.-controlled glass tube belongs to the common temperature sensing device of fire-fighting spraying head, belongs to
In known technology, this will not be detailed here.
As further embodiment, it is additionally provided with the front and back guide rod being directed toward between the fixed seat and unlock slide, is oriented to
Bar one end is fixedly connected with slide is unlocked, and one end of the fixed seat towards unlock slide is equipped with pilot hole, pilot hole and guiding
Bar slides back and forth cooperation.The cooperation of guide rod and pilot hole so that fixed seat keeps linear relation with unlock slide；In addition, solid
Being involved by rocking bar between reservation and unlock slide, in conjunction with the effect of guide rod so that fixed seat is not easy to loosen with unlock slide,
Temp.-controlled glass tube and compressed spring are not easily to fall off.
As further embodiment, the fluting of front and back direction is equipped in the middle part of the fixed seat, rocking bar is located in fluting, fluting
Unlock secondary spring is equipped between in front of the swinging center of bottom and rocking bar.When elastic component active force loses, assisted in unlock
Under the action of spring, rocking bar will actively leave slide block assembly, and fireproofing function is more reliable.
As further embodiment, the corresponding rocking bar other end is equipped with the first recessing groove in the middle part of the unlock slide, and first allows
It is equipped with skewed slot at left and right sides of the slot of position；The rocking bar is equipped with the lateral pin that left and right is directed toward, and lateral pin is equipped with idler wheel, and idler wheel is along the oblique of skewed slot
Face rolls.Idler wheel helps to reduce the friction with skewed slot so that the movement for unlocking slide is more smooth.
As further embodiment, one end that the rocking bar is equipped with latch hook is stretched out in front of fixed seat, the slide block assembly packet
It includes sliding block and for the lock pin with latch hook snapping, the corresponding rocking bar in sliding block middle part is equipped with the second recessing groove, and lock pin setting allows second
In the slot of position.
As further embodiment, the fixed seat and/or unlock slide correspond to temp.-controlled glass tube installation site equipped with scarce
Mouthful.If remaining in temperature control solution locking after temp.-controlled glass tube explosion to determine, without falling down on device, to stop that unlock slide moves ahead,
Cause rocking bar that cannot swing and be detached from slide block assembly；But by be arranged notch after so that temp.-controlled glass tube explosion after be not easy it is residual
It stays, it is ensured that freely activity, rocking bar may be implemented to unlock unlock slide.
Beneficial effects of the present invention are as follows：
（1）The present invention changes the elastic force of elastic component by guide screw movement regulating part, to change between fixed seat and unlock slide
Elastic force so that unlock required strength and be changed, be suitble to a variety of unlocking mechanisms requirement；
（2）The device that stops determining of the present invention also comes with temp.-controlled glass tube so that it can automatic unlocking at a certain temperature, to meet
Fire-fighting requirements；Moreover, when installation, through-hole of the temp.-controlled glass tube through fixed seat can first be entered to the location hole of unlock slide,
Then toward through-hole be packed into compressed spring, chock plug is finally screwed into through-hole, you can with the help of no tooling install compressed spring and
Temp.-controlled glass tube, it is easy for installation.
