Description
Technical field
The utility model relates to blower fan technical field, relates to a kind of small-sized fan volume adjusting apparatus specifically.
Background technique
The air door regulating mechanism of existing blower is of a great variety, and as a rule, most air door needs to use screw or other parts manually to be reorientated after adjustment, and such adjustment extremely bothers, and increases blower internal pressure, shortens the blower life-span.If blower fan in the course of the work, needs the size of damper at any time, if need manually to go stubborn screw to locate after each damper, then can waste the more time, affect working efficiency.
Model utility content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of small-sized fan volume adjusting apparatus, and this device is that air door can freely navigate on required adjustment position without gear regulative mode, save regulating time, after removing adjustment from, manually tighten up the trouble of location.
To achieve these goals, the technical solution adopted in the utility model is: a kind of small-sized fan volume adjusting apparatus, comprise blower fan air outlet tube, air door plate, adjustment seat, steel wire pull line and spring, the circular in cross-section of described blower fan air outlet tube, along laterally having short slot on blower fan air outlet tube, blower fan air outlet tube is installed with adjustment seat; Described air door plate is positioned at the short slot of blower fan air outlet tube, and can slide in short slot, air door plate is fixed with regulator plate, tapped through hole is had at the middle part of regulator plate, connecting plate is fixed with in the upper end of regulator plate, the medial axis of its connecting plate and the medial axis of regulator plate perpendicular, and in the same plane with air door plate; The middle part of described adjustment seat is provided with tapped blind hole, correspond to connecting plate symmetry in the upper end of adjustment seat and be fixed with fixed connecting plate, its air door plate by pin, tapped through hole and tapped blind hole and adjustment seat hinged, its steel wire pull line is fixedly connected with one end of connecting plate by fixed connecting plate, and the two ends of its spring are separately fixed on the other end of fixed connecting plate and connecting plate; Described spring is extension spring, and is positioned at the top of short slot.
Preferably, the appearance of described steel wire pull line is provided with fixed seating and sliding sleeve, and fixed seating is positioned at the two ends of sliding sleeve, and one fixed seating is fixed on fixed connecting plate.
Further, the radian of described short slot is not less than 180 degree.
Further, described air door plate is also provided with breach, the area of its breach and the minimum air output of blower fan adapt.
Adopt the model utility of the technical program, its beneficial effect is: volume adjusting apparatus of the present utility model, due to the setting of short slot, regulator plate, connecting plate, pin, tapped through hole and tapped blind hole, therefore this device is that its air door can freely navigate on required adjustment position without gear regulative mode; This not only saves the regulating time of air door, and eliminates the trouble manually tightening up location after air door regulates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1, blower fan air outlet tube; 2, air door plate; 3, adjustment seat; 4, pin; 5, steel wire pull line; 6, spring; 11, short slot; 21, regulator plate; 22, connecting plate; 23, breach; 31, fixed connecting plate; 51, fixed seating; 52, sliding sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, volume adjusting apparatus of the present utility model, comprise blower fan air outlet tube 1, air door plate 2, adjustment seat 3, steel wire pull line 5 and spring 6, the circular in cross-section of described blower fan air outlet tube 1, along laterally having short slot 11 on blower fan air outlet tube 1, blower fan air outlet tube 1 is installed with adjustment seat 3; Described air door plate 2 is positioned at the short slot 11 of blower fan air outlet tube 1, and can slide in short slot 11, air door plate 2 is fixed with regulator plate 21, tapped through hole is had at the middle part of regulator plate 21, connecting plate 22 is fixed with in the upper end of regulator plate 21, the medial axis of its connecting plate 22 and the medial axis of regulator plate 21 perpendicular, and in the same plane with air door plate 2; The middle part of described adjustment seat 3 is provided with tapped blind hole, correspond to connecting plate 22 symmetry in the upper end of adjustment seat 3 and be fixed with fixed connecting plate 31, its air door plate 2 by pin 4, tapped through hole and tapped blind hole and adjustment seat 3 hinged, its steel wire pull line 5 is fixedly connected with by fixed connecting plate 31 one end with connecting plate 22, and the two ends of its spring 6 are separately fixed on the other end of fixed connecting plate 31 and connecting plate 22; Described spring 6 is extension spring, and is positioned at the top of short slot 11.The appearance of described steel wire pull line 5 is provided with fixed seating 51 and sliding sleeve 52, and fixed seating 51 is positioned at the two ends of sliding sleeve 52, and one fixed seating 51 is fixed on fixed connecting plate 31.The radian of described short slot 11 is 200 degree.Described air door plate 2 is also provided with breach 23, and the area of its breach 23 and the minimum air output of blower fan adapt.
In using, first loose fixed seating 51 is fixed on the object near blower fan, steel wire pull line 5 is had an effect with pulling force and locking mechanism is fixedly connected with.When steel wire pull line 5 is without pulling force, due to the effect of spring 6, air door plate 2 is positioned at short slot 11 completely, and the air output of blower fan is limited in the scope that adapts with breach 23 area; When steel wire pull line 5 has pulling force, regulator plate 21 rotates around pin 4, and drive air door plate 2 to slide along short slot 11, air door plate 2 strengthens with the gap of the interior caliber of blower fan air outlet tube 1, the air output of blower fan can strengthen, the length that its steel wire pull line 5 pulls strengthens to the air output of blower fan and is directly proportional, and so namely realizes regulating and location without gear of air door.
Above are only a kind of embodiment of the present utility model, not in order to limit the utility model, all any amendments done within spirit of the present utility model and principle are equivalent to be replaced and improves, and all should be included within protection domain of the present utility model.
