Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment 1
It please refers to Fig.1 shown in -4, a kind of roof automatic fume exhauster, including roof 1, supporting rod 3, connecting rod 5, fixed ring
7, the first slip ring 9, umbrella cover 11, the second slip ring 13, through-hole 15, drawstring 17 and pulling block 18 are provided with chimney 2, and chimney on roof 1
2 side is provided with belt 6, and belt 6 slides up and down, and on the one hand moves the position of the first slip ring 9, on the other hand
The position of second slip ring 13 is moved therewith together, the both ends of belt 6 are socketed in connecting rod 5, and the top of connecting rod 5
On the side wall of column 4, and the another side side wall of column 4 is located on the side wall of supporting rod 3, and supporting rod 3 is so that belt 6 has one
The effect of a support, and the top of supporting rod 3 is provided with jack-post 12, the top of jack-post 12 is located at the bottom end of umbrella cover 11, by setting
It sets umbrella cover 11, thus to that can make the rainy day when by umbrella cover 11, is the effect of a protection to chimney 2, and umbrella cover 11
Bottom end be symmetrically arranged with several diagonal braces 10, diagonal brace 10 can to the folding of umbrella cover 11 there are one the effect controlled, diagonal brace 10
Bottom end is located on the first slip ring 9, and the bottom end of the first slip ring 9 is provided with connecting pole 8, and the other end of connecting pole 8 is located at belt 6
On outer wall.
Embodiment 2
Please continue to refer to shown in Fig. 1-4, compared with above-described embodiment, connect in rotation between belt 6 and the outer wall of connecting rod 5
It connects, and the top of connecting rod 5 is provided with fixed ring 7, the diameter of fixed ring 7 is more than the diameter of connecting rod 5, by the way that fixed ring is arranged
7, thus to position of the belt 6 in connecting rod 5, there are one fixed effects, avoid falling off from connecting rod 5.Outside belt 6
Another group of connecting pole 8 is provided on wall, the other end of another group of connecting pole 8 on the outer wall of belt 6 is connected with the second slip ring 13,
And second slip ring 13 be socketed on the outer wall of chimney 2, the first slip ring 9 and the second slip ring 13 are outer with supporting rod 3 and chimney 2 respectively
In being slidably connected between wall, by being in be slidably connected, thus reduce the first slip ring 9 and the second slip ring 13 and support between each other
Frictional force between bar 3 and chimney 2.The top of second slip ring 13 is connected with top plate 14, and in top plate 14 and the second slip ring 13
Centre, which is run through, through-hole 15, is slided on chimney 2 by the way that through-hole 15 is arranged, thus convenient for the second slip ring 13 and top plate 14.
Drainage tube 16 is both provided on the both sides side wall of second slip ring 13, and the height of umbrella cover 11 is more than the height of chimney 2, passes through setting
