Specific embodiment
The utility model technical solution claimed is made further specifically now in conjunction with the drawings and specific embodiments
It is bright.
Referring to shown in Fig. 1 to Fig. 3, one of the present embodiment fire window Multi-angle limit mechanism, including connect with window frame 4
Window frame kerve component, the sash kerve component that connect with sash 5 and be connected to window frame kerve component and sash kerve component
Between strut 3.
Wherein window frame kerve component includes the window frame kerve main body 11 extended in the same direction with 4 bottom edge of window frame, is slidably connected to institute
State the first sliding block 12 in window frame kerve main body 11, for the first positioning mechanism of the first sliding block of locking 12.In the present embodiment,
First positioning mechanism includes the pin shaft 134 for cooperating the pin hole 121, the axis pin base 131 being sheathed on outside pin shaft 134, for band
Dynamic pin shaft 134 pops up the spring 132 and temperature detect switch (TDS) 133 of pin hole 121, and the axis pin base 131 and window frame kerve main body 11 are solid
Fixed connection.In the present embodiment, the both ends of spring 132 press the flange of 134 lower end of 131 upper end of axis pin base and pin shaft simultaneously respectively
And elastic compression forms it into the elastic force that pin shaft 134 is popped up to pin hole 121 to the spring 132 under normal conditions.In the present embodiment, warm
The end of control switch 133 contradicts 134 lower end of pin shaft to make pin shaft 134 be kept in insertion pin hole 121 under normal conditions, in this implementation
The end of temperature detect switch (TDS) 133 exposes to window frame using meltable material in example, and when temperature reaches critical value, its end fuses, end
Head is driven retraction wherein to contradict again to pin shaft 134 by spring, deviates from pin hole in the drive lower bearing pin 134 of spring 132
121 to the first positioning mechanism of unlock, and the first sliding block 12 can be free to slide along window frame kerve main body 11, if cooperation, which closes page certainly, to be made
With achievable sash 5 from the effect closed under the hot environments such as fire.
Sash kerve component includes the sash kerve main body 21 extended in the same direction with 5 bottom edge of sash, is slidably connected to the window
Fan the second sliding block 22 in kerve main body 21, for the second positioning mechanism of second sliding block 22,3 both ends of the strut difference
It is hinged with the first sliding block 12 and the second sliding block 22.In the present embodiment, second sliding block 22 is provided with multiple level holes 221, institute
Stating the second positioning mechanism includes box body 231, the flexible positioning pin 232 being packaged in box body 231, lock chamber 233, reset spring
234 and pull rod 235, wherein the flexible positioning pin 232 and level hole 221 cooperate, the lock chamber 233 and flexible positioning pin 232
It is slidably connected so that flexible positioning pin 232 is flexible, the reset spring 234 is for driving flexible positioning pin 232 to stretch out, the box
Body 231 is fixedly connected with sash kerve main body 21, pull rod 235 and sash kerve main body 21 extend in the same direction and with 231 structure of box body
At being slidably connected on its length direction, the pull rod 235 forms mutually matched guiding surface with flexible positioning pin 232
236.In the present embodiment, the opening of sash 5 is adjusted with the mating reaction in multiple level holes 221 using flexible positioning pin 232
The angle and level for forming multi-angle is located in sash 5 according to demand under multiple and different open angles, can specifically pass through
The mode for pulling pull rod 235 makes flexible positioning pin using the guiding surface 236 of pull rod 235 and the mutual cooperation of flexible positioning pin 232
232 retract the second positioning mechanism of unlock in lock chamber 233, keep the second sliding block 22 free to slide along sash kerve main body 21, thus
Open sash 5 can freely；Behind releasing lever 235, stretch auto-extending under the action of reset spring 234 of positioning pin 232,
As sash 5 can be fixed on current opening angle to criterion by the level hole 221 of stretch at this time positioning pin 232 and the second sliding block 22
Degree.
The principles of the present invention are as follows: in normal conditions, first positioning mechanism of the present embodiment keeps lock state,
The handle being sequentially connected with pull rod 235 is first operated when user's normal switch sash 5, pulls pull rod 235 by level until stretching
Contracting positioning pin 232 is then opened or closed sash 5, second during sash 5 switchs by driving in retraction lock chamber 233
Sliding block 22 is free to slide and strut 3 is driven to swing, and unclamps handle after sash 5 is opened to certain angle, and flexible positioning pin 232 exists
It is suppressed downwards under the drive of reset spring 234, if the level hole 221 of flexible positioning pin 232 and the second sliding block 22 is to criterion at this time
Flexible positioning pin 232, which is inserted into level hole 221, is fixed on sash 5 under current angular.
When environment temperature is increased to the critical-temperature of temperature detect switch (TDS) 133 because of factors such as fire behaviors, the end of temperature detect switch (TDS) 133
Fusing causes its end to be driven retraction wherein by spring, to can not contradict again to pin shaft 134, sells under the drive of spring 132
Axis 134 deviates from pin hole 121 to the first positioning mechanism of unlock, and the first sliding block 12 can be free to slide along window frame kerve main body 11, this
Shi Peihe from page is closed makes that sash 5 is driven to close, to play fireproofing function.
The embodiment of the above is only the preferred embodiment of the utility model, not does any form to the utility model
On limitation.Anyone skilled in the art all can benefit in the case where not departing from technical solutions of the utility model ambit
More possible variations and retouching are made to technical solutions of the utility model with the technology contents of the disclosure above, or are revised as equivalent
The equivalent embodiment of variation.Therefore all contents without departing from technical solutions of the utility model, the thinking according to the utility model are made
Equivalent equivalence changes, should all be covered by the protection scope of the utility model.
