Work of the fire prevention limiter 10 when fire occurs and fire does not occur briefly is introduced now in conjunction with Fig. 1 and Fig. 9-12
Make principle:
When fire not occurring, Fig. 1 is the structural schematic diagram in the open state of fan structure 30, and Fig. 9 is that fan structure 30 is in
The structural schematic diagram of closed state.When needing for the fire prevention limiter 10 to be switched to the state of Fig. 9 from the state of Fig. 1, please join
12 are examined, handle 31 is pulled, that is, the rotation of fan structure 30 may make to open.Since environment temperature does not reach the pole of steady sensing unit 500
Temperature value is limited, temperature element (TE 500 does not damage, and sliding block 200 is fixed in sliding rail 100 at this time, and any movement does not occur.Work as needs
When fan structure 30 after unlatching certain angle is fixed, only need to tighten locking member 820 makes first connecting rod 310 and second connecting rod
Opposite slide does not occur for 320 abuttings.
When fire occurs, Figure 10 is the structural schematic diagram in the open state of fan structure 20, and Figure 11 is that fan structure 20 is in
The structural schematic diagram of closed state.When the fire occurs, the fire prevention limiter 10 will be switched to the state of Figure 11 from the state of Figure 10.
Since the generation of fire is so that environment temperature reaches the Limit temperature value of temp-sensing element 500, temp-sensing element 500 is damaged, limited block
400 lose the abutting force effect of temp-sensing element 500, under the action of 600 screen resilience of elastic component, the first limited block 410 and second
Limited block 420 will fall off from the first notch 201 and the second notch 202, and slide into the first limiting slot 101 and the second limit respectively
In slot 102, meanwhile, sliding block 200 slides the one end for being directed away from link mechanism 300, by taking the visual angle Figure 11 as an example, so as to logical
Crossing link mechanism 300 drives fan structure 30 to rotate counterclockwise, to realize switching of the fan structure 30 from open state to closed state.
Meanwhile the present invention also provides a kind of frame fan structures, including above-mentioned fire prevention limiter 10, mount structure 20 and fan structure
30.Sliding rail 100 is fixed on mount structure 20, and the one end of link mechanism 300 far from sliding block 200 and fan structure 30 are rotatablely connected.It can
To understand, in other embodiments, the one end of link mechanism 300 far from sliding block 200 can also be with the conjunction in the frame fan structure
Page rotation connection.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
