Embodiment
Technical scheme is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to a kind of double-reed fire prevention automatic window closing device shown in Fig. 1 to Fig. 3, it is arranged on window-frame frame and window side frame
Between.Shutting window device include be arranged on window frame on device body 1, the positioning seat 2 on window side frame, both ends respectively with
The rocking arm 3 that device body 1 connects with the phase pivot of positioning seat 2.Device body 1 include be fixed in window frame chute 4, located at chute 4
It is interior to be used for rocking arm 3 and device body 1 with respect to being locked so that window is positioned at the locking mechanism 10 of open mode and is used for
Rocking arm 3 is driven with respect to the unlocking mechanism 5 that device body 1 slidably closes window.
Locking mechanism 10 include in the chute 4 can along the sliding block 12 that the length direction of chute 4 reciprocatingly slides, located at chute 4
Spring leaf 11 on the inwall of both sides.One end of rocking arm 3 and sliding block 12 are pivotally connected so that rocking arm 3 and sliding block 12 can mutual bands
The action of window is carried out dynamicly.Spring leaf 11 includes body, the clamping part to be arched upward from body to the middle part of chute 4, two clampings
Clamping lock room is formed between portion, when locking mechanism 10 locks, clamping part is clamped in the both sides of sliding block 12.
Unlocking mechanism 5 include being arranged on locating rack 9 in chute 4, along the extension of the length direction of chute 4 unblock frame 6, with
And elastic component 7 and warming glass marble 8.Wherein locating rack 9 is provided with location division 92a and limiting section 92b, and elastic component 7 is positioned at spacing
Between portion 92b and unblock frame 6 and the promotion unblock unlocking movement trend of frame 6 is remain, the both ends of warming glass marble 8 contradict respectively
Between location division 92a and unblock frame 6.When a fire, warming glass marble 8 rises and quick-fried broken, bullet with the temperature of interior
Property part 7 recover deformation unblock frame 6 promoted to locking mechanism 10 and sliding block 12 is ejected and unlocked from clamping lock room.
Preferably, the both sides of sliding block 12 are provided with the depressed part 12a being engaged with clamping part, when locking mechanism 10 locks, folder
The portion of holding is clamped in depressed part 12a so that the state that spring leaf 11 forms locking with sliding block 12 is more stable.The rear end of sliding block 12
Both sides are provided with lug boss 12b, and the end of spring leaf 11 is engaged with lug boss 12b is continued to unlocking mechanism 5 with limiting sliding block 12
Motion so that in windowing action, sliding block 12 will not contradict unblock frame 6, so as to ensure the stabilization of unlocking mechanism 5.Further
Preferably, the slope in the clamping part of spring leaf 11 close to the side of unlocking mechanism 5 is more than the slope away from the side of unlocking mechanism 5.
It is easier so that sliding block 12 enters in the clamping lock room that two spring leafs 11 are formed, the clamping formed from two spring leafs 11
It is out relatively difficult in lock room so that the locking effect of locking mechanism 10 is more preferable.
Locating rack 9 includes the locating piece 91 being located on chute 4, the body frame 92 being fixedly connected with locating piece 91, location division 92a
The both ends of body frame 92 are respectively arranged on limiting section 92b.Spring leaf 11 can be also fixedly connected with locating piece 91.By locating piece 91, master
Frame 92, the phase of spring leaf 11 are fixedly connected, and it can be made to be easily installed in chute 4, dismantle and move, also allow for carrying out window
Locking and unblock.
Unblock frame 6 includes trip lever 61, the setting that can be movably arranged at along the length direction of chute 4 on locating rack 9
Thimble block 62 on trip lever 61, locating rack 9 are provided with the through hole passed through for trip lever 61.Preferably, unlocking frame 6 includes two
The trip lever 61 of root parallel setting in the horizontal direction, two front ends of trip lever 61 are additionally provided with the company of two trip levers 61 of connection
Bar so that unblock frame 6 promotes that the area of locking mechanism 10 is bigger, effect is more preferable.Warming glass marble 8 located at two trip levers 61 it
Between, and its bearing of trend is identical with the bearing of trend of trip lever 61.The both ends of warming glass marble 8 contradict respectively thimble block 62 with
Between the 92a of location division, the groove placed for warming glass marble 8 is equipped with thimble block 62 and location division 92a so that it is more steady
It is fixed.
Elastic component 7 is spring, and both ends of the spring is inconsistent with limiting section 92b and thimble block 62 respectively, and spring is in compression
State.When a fire, warming glass marble 8 is quick-fried broken with indoor temperature rising, and spring recovers deformation and pushes unblock frame 6 to
Locking mechanism 10 simultaneously causes locking mechanism 10 to unlock.
In summary, in the present embodiment, double-reed fire-proof automatic window closing device has two use states：
First, under in a safe condition, it can adopt manually, promote positioning seat 2, moved by positioning seat 2 with motion rocker arm 3, then
Run by rocking arm 3 with length direction of the movable slider 12 along chute 4, sliding block 12 is entered spring leaf 11 and form clamping lock room,
Then clamping part is clamped in the depressed part 12a of sliding block 12, and locking mechanism 10 forms lock-out state, and now window stays open shape
State.When needing to close window, adopt manually, pull positioning seat 2, sliding block 12 moves under the drive of rocking arm 3, sliding block 12
From the clamping lock room that spring leaf 11 is formed out, and in the case where window is conducted oneself with dignity, rocking arm 3 is with movable slider 12 along chute
4 length direction operation, so as to which window be closed.
2nd, under in the hole（During fire）, warming glass marble 8 occurs quick-fried with gradually rising for indoor temperature
Broken, elastic component 7 drives unblock frame 6 to be moved to locking mechanism 10, until trip lever 61 promotes sliding block 12 to make its motion, sliding block 12 from
In the clamping lock room that spring leaf 11 is formed out after in the case where window is conducted oneself with dignity, rocking arm 3 is with movable slider 12 along chute 4
Length direction is run, so as to which window be closed.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all be included within the scope of the present invention.
