Abstract
A rotatable outlet device of a ventilating fan, which is simple and reasonable in structure and favorable for venting air comprises a fixed section (1), a longitudinal ring (2), a moving section (3) and the like. The rotatable outlet device of the ventilating fan is characterized in that the moving section (3) is sleeved on the fixed section (1), a woven metal screen (12) is arranged at the position of an outlet of the moving section (3), and a wind deflection fin (13) is arranged outside the outlet of the moving section (3). A horizontal convex ring (4) of the moving section (3) is sleeved on the longitudinal ring (3) of the fixed section (1), and the moving section (3) and the fixed section (1) are fixed through a bearing and a longitudinal shaft (5), so that the moving section (3) can rotate on the fixed section (1) at an angle of 360 and is not easy to separate from the fixed section (1); and the moving section (1) can rotate along a direction of natural wind and can be automatically adjusted to a position which is the most suitable for venting the air through the wind deflection fin (13) mounted on the moving section (1), so that the air can be vented easily, and air backward-flowing can be eliminated.
Description
Technical field
The utility model relates to a kind of outlet device of ventilating fan, relates in particular to a kind of rotatable ventilating fan outlet device.
Background technique
The experiment place of R&D institution, colleges and universities' chemical and the workshop that produces dust generally all can be equipped with the ventilation exhaust equipment, and the waste gas that produces in experiment or the production process, dust etc. are in time emitted.But mostly common ventilating fan outlet device is fixed; When natural wind-force is big,, the outlet external part of wind direction and ventilating fan will be difficult to discharge if, producing waste gas or dust towards inconsistent in the experimentation; The situation that also can occur downdraught sometimes, the carrying out of influence experiment.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provide a kind of simple and reasonable, be beneficial to the rotatable ventilating fan outlet device of discharging gas, by holding part (1), vertically ring (2), active segment (3), laterally bulge loop (4), the longitudinal axis (5), fixing frame A (6), bearing A (7), bearing B (8), bearing C (9), bearings D (10), fixing frame B (11), metal knitted net (12), wind-guiding wing (13) constitute, and it is characterized in that the holding part upper end of " L " shape is provided with vertical ring; Vertically the external diameter of ring is less than the external diameter of holding part; The lower end of the active segment of " 7 " shape is provided with inside horizontal bulge loop, and laterally the internal diameter of bulge loop is slightly larger than the external diameter of vertical ring, and active segment is sleeved on the holding part; The set inside of holding part and active segment has a longitudinal axis; The lower end of the longitudinal axis is positioned at the groove of fixing frame A, and fixing frame A is fixed in the curved part of holding part, and the upper end of the longitudinal axis is positioned at fixing frame B; Fixing frame B is fixed in the curved part of active segment; Bearing A, bearing B, bearing C, bearings D are sleeved on the said longitudinal axis successively, and bearing A is fixed on the fixing frame A, and bearing B is fixed on the inwall at holding part vertical component middle part through cross; Bearing C is fixed on the inwall at active segment vertical component middle part through cross; Bearings D is fixed on the fixing frame B, and the outlet port of active segment is provided with metal knitted net, and the outlet outer installment of active segment has the wind-guiding wing.
The beneficial effect of the utility model is: the horizontal bulge loop of active segment is enclosed within on vertical ring of holding part, and both fix through the bearing and the longitudinal axis again, makes active segment can on holding part, accomplish 360 ° and rotates and can not break away from easily; Through the wind-guiding wing of installing on the active segment, active segment can rotate with the wind direction of natural wind, adjusts to the position of suitable exhaust automatically, helps the discharge of gas, has stopped the generation of downdraught situation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, holding part (1) is " L " OK, and the upper end is provided with vertical ring (2); Vertically the external diameter of ring (2) is less than the external diameter of holding part (1); Active segment (3) is " 7 " OK, and the lower end curves inwardly and forms horizontal bulge loop (4), and laterally the internal diameter of bulge loop (4) is slightly larger than the external diameter of vertical ring (2); Laterally the top of bulge loop (4) closely contacts with the outer side wall that vertically encircles (2); Through horizontal bulge loop (4) and vertical ring (2), active segment (3) is sleeved on the holding part (1), and active segment (3) can rotate freely on holding part (1); A longitudinal axis (5) runs through the inside of holding part (1) and active segment (3); The lower end of the longitudinal axis (5) is positioned at the circular groove of fixing frame A (6), and fixing frame A (6) is welded in the curved part of holding part (1), and the upper end of the longitudinal axis (5) is positioned at the circular groove of fixing frame B (11); Fixing frame B (11) is welded in the curved part of active segment (3); Bearing A (7), bearing B (8), bearing C (9), bearings D (10) are sleeved on the longitudinal axis (5) successively, and bearing A (7) is fixed on the fixing frame A (6), and bearing B (8) is fixed on the inwall at holding part (1) vertical component middle part through cross; Bearing C (9) is fixed on the inwall at active segment (3) vertical component middle part through cross; Bearings D (10) is fixed on the fixing frame B (8), and the longitudinal axis (5) can arbitrarily rotate in bearing and fixing frame, and the longitudinal axis (5) has played the fixation to active segment (3); The outlet port of active segment (3) is equipped with metal knitted net (12), can prevent that the solid of bulk from getting into this device, stops up ventilating fan or damages internal components; The outlet outside of active segment (3) is equipped with wind-guiding wing (13), and natural wind blows wind-guiding wing (13), drives active segment (3) and rotates.
