Abstract
The utility model relates to a bidirectional ventilator positioning mechanism with rotation reversing, which aims at improving the defect that the ventilator in the prior art continually rotates around a central shaft backwards and forwards. The bidirectional ventilator positioning mechanism with rotation reversing is realized by comprising a frame and a stay wire in the prior art, and is characterized in that two spring dampers are arranged on the frame, and the stay wire is arranged between two clamping wheels of the spring dampers. When the stay wire is fixed by the spring dampers, the rotation of the ventilator is controlled. The bidirectional ventilator positioning mechanism has the advantage of simple structure, not only solves the controlling problem of ventilator rotation, but also has ultra-convenient operation.
Description
Affiliated technical field
The utility model is the positioning means about a kind of dual direction ventilating fan.
Background technique
Known dual direction ventilating fan is that the motor with unidirectional ventilation fan makes into and can positive and negatively rotate, and carries out air inlet and exhaust with this.Its fan sheet mainly is vent design.When its air inlet, be to calm the anger by the back side of this fan sheet to carry out.Its shortcoming is that air inflow is littler than air displacement, and noise increases more than at least ten decibels during than exhaust.In order to overcome the deficiency of above-mentioned technology, (see that Fig. 1-Fig. 3) provides a kind of like this dual direction ventilating fan: during its air inlet, air quantity and noise are the same during with unidirectional ventilation fan exhaust to patent CN201292970Y.Be characterized in central shaft 11 and wire spool 12 are set on the unidirectional ventilation fan 1 of prior art, and set up framework 4 and backguy 2 and 3.The pulling backguy just can make ventilation fan rotate in framework 4, thereby can forward inwardly ventilation fan face outwardly to the opposite is also true.Like this, just reached the purpose of carrying out exhaust and air inlet with unidirectional ventilation fan.Thereby the shortcoming that air quantity is little, noise is big when having avoided known dual direction ventilating fan air inlet.
But find that nowadays patent CN201292970Y has such shortcoming: in service at ventilation fan, owing to lack positioning means, ventilation fan constantly swings back and forth around central shaft, causes air output or air displacement instability, has also increased noise simultaneously.
Summary of the invention
The purpose of this utility model is to improve ventilation fan in the prior art constantly comes back rotation around central shaft defective.
The utility model is achieved in that it comprises the framework and the backguy of prior art, it is characterized in that being provided with on described framework two spring-dampers, and described backguy is arranged between two clip wheels of spring-damper.Backguy has just been controlled the random rotation of ventilation fan around central shaft after being controlled by spring-damper.
The beneficial effects of the utility model are: simple in structure, but reached the problem that the control ventilation fan rotates around central shaft.Operate also very convenient.

Embodiment
Two spring-dampers 9 (can buy on the market, belong to prior art) are set on the framework 4 of (seeing Fig. 4 and Fig. 7) prior art, and backguy 2 and 3 is arranged between two clip wheels 91 of spring-damper 9.Backguy 2 or 3 can be moved between clip wheel 91.But because under the effect of spring 92, the motion of backguy needs just can move under people's the application of force, like this, has just controlled ventilation fan 1 and has arbitrarily rotated around central shaft 11.
