Abstract
The utility model provides a formula safety device against wind is adjusted to shutter scavenger fan threaded rod, accessible rotate the swing arm and realize the control tripe degree of opening and shutting the most greatly, effective wind direction of giving vent to anger of adjusting to even under extreme weather environment such as typhoon, thereby also can control the tripe switching and avoid violent switching tripe to lead to the fact the damage of scavenger fan.
Description
Technical field
The utility model is a kind of shutter type vetilation fan threaded rod adjustable type wind-proof device, belongs to the renovation technique of shutter type vetilation fan.
Background technology
The blast that after existing shutter type vetilation fan adopts energising, high-speed rotation ventilation fan causes to promote blinds, thus realizes automatically closing folding shutter, and structure is simple and convenient.But as run into the extreme strong convection weathers such as typhoon, it is closed that the very big change due to inner and outer air pressure causes shutter strongly to open, and very easily causes ventilation fan to damage.
Summary of the invention
For the deficiency of above-mentioned technology, the utility model provides a kind of easy to use, structure simple shutter type vetilation fan threaded rod adjustable type wind-proof device.
To achieve these goals, technical solution adopted in the utility model is: a kind of shutter type vetilation fan threaded rod adjustable type wind-proof device, is made up of ventilation fan 1, threaded rod adjustable type wind-proof device 2; Described ventilation fan 1 is made up of ventilation fan shell 11, electric fan 12, movable shutters 13, spring 14, electric fan 12 is fixed on ventilation fan shell 11 opening side, movable shutters 13 is fixed on ventilation fan shell 11 opposite side, movable shutters 13 is made up of adjustable shelf 131 and louvre blade 132, spring 14 one end is fixed on ventilation fan shell 11, and its other end is fixed on edge on blinds fan adjustable shelf 131; Threaded rod adjustable type wind-proof device 2 is made up of swing arm 21 and screw thread 22, and swing arm 21 is fixed on ventilation fan shell 11, and adjustable shelf 131 one end contacts with screw thread 22.
The utility model has the advantage of: a kind of shutter type vetilation fan threaded rod adjustable type wind-proof device, realize controlling the maximum folding degree of blinds by rotating swing arm, effective adjustment is given vent to anger wind direction, even and if under the extreme weather environment such as typhoon, also can shutter opened be controlled thus avoid violent opening and closing blinds to cause the damage of ventilation fan.

Fig. 1 is section structural scheme of mechanism of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of threaded rod adjustable type wind-proof device of the present utility model.
1 ventilation fan, 11 ventilation fan shells, 12 electric fans, 13 movable shutters, 131 adjustable shelfs, 132 louvre blades, spring 14,2 threaded rod adjustable type wind-proof device, 21 swing arms, 22 screw threads in figure.
Detailed description of the invention
As shown in Fig. 1 ~ 3, a kind of shutter type vetilation fan threaded rod adjustable type wind-proof device, is made up of ventilation fan 1, threaded rod adjustable type wind-proof device 2; Described ventilation fan 1 is made up of ventilation fan shell 11, electric fan 12, movable shutters 13, spring 14, electric fan 12 is fixed on ventilation fan shell 11 opening side, movable shutters 13 is fixed on ventilation fan shell 11 opposite side, movable shutters 13 is made up of adjustable shelf 131 and louvre blade 132, spring 14 one end is fixed on ventilation fan shell 11, and its other end is fixed on edge on blinds fan adjustable shelf 131; Threaded rod adjustable type wind-proof device 2 is made up of swing arm 21 and screw thread 22, and swing arm 21 is fixed on ventilation fan shell 11, and adjustable shelf 131 one end contacts with screw thread 22.When be pressed in inside and outside typhoon etc. extreme weather environment causes in short-term strong variations time, rotate lower swing arm 21, screw thread 22 is rotated thereupon and promotes adjustable shelf 131 to limit its activity, make louvre blade 132 cannot smooth opening, thus control the opening and closing of movable shutters 13, avoid because avoiding violent opening and closing louvre blade 132 to cause the damage of ventilation fan.
