Abstract
The utility model relates to a fan with an adjustable blade angle, which comprises a fan shell, a motor and blades, wherein the motor is fixed on an inner wall of the fan shell; a check block is fixedly arranged on a main shaft of the motor; a screw thread section is formed on the main shaft, and is inserted in central holes of a left blade installation plate and a right blade installation plate; a mainshaft nut is bolted on the screw thread section, and is leaned against an end face of the right blade installation plate in a pressing way; a left convex rib accommodating nest and a right convex rib accommodating nest are respectively formed in the left blade installation plate and the right blade installation plate; convex ribs are formed on the blades and are clamped between the left convex rib accommodating nest and the right convex rib accommodating nest; a plurality of wedged slots are formed on a bottom face of the right convex rib accommodating nest; wedged lugs are formed on the convex ribs and are inserted into the wedged slots; and adjustable bolts penetrate through the left blade installation plate and the right blade installation plate so as to be bolted with the nut, and can be used for directly adjusting the blades so as to achieve the effect of adjusting air quantity, so that the air quantity can be simply and conveniently adjusted.
Description
Technical field:
The utility model relates to the ventilator technical field, more specifically to the adjustable ventilator in leaf angle.
Background technique:
Existing ventilator is when regulating air quantity; Generally be that wind inlet or exhaust outlet at ventilator is equipped with devices such as controllable register; Regulate air quantity ground size through controllable register; The volume adjusting apparatus that this just need also want installation and design to be complementary with it when ventilator is installed, this makes that not only cost that ventilator is installed has improved, and makes become complicacy and bothering of air quantity ground adjusting.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And provide the leaf angle adjustable ventilator, it directly adjusting vane reach the effect of regulating air quantity, make that the adjusting of air quantity becomes simply, make things convenient for; And no longer need provide cost savings specially for it is equipped with volume adjusting apparatus.
The technological solution of the utility model is following:
The ventilator that the leaf angle is adjustable comprises Blower Housing, motor and blade, and motor is fixed on the inwall of Blower Housing; Be fixed with block on the main shaft of motor; And form thread section on the said main shaft, said thread section sleeve is in the center hole of mounting disc of lobus sinister sheet and the mounting disc of lobus dexter sheet, and mainshaft nut is screwed onto thread section; And this mainshaft nut is pressed against on the end face of lobus dexter sheet mounting disc; Mounting disc of said lobus sinister sheet and the mounting disc of lobus dexter sheet form respectively that left convex tendon is accommodated nest and right convex tendon is accommodated nest, form convex tendon on the blade, and this convex tendon is clamped in that left convex tendon is accommodated nest and right convex tendon is accommodated between the nest; Said right convex tendon is accommodated on the bottom surface of nest and is formed some wedge grooves; Form the wedge lug on the said convex tendon, wedge lug sleeve is in the wedge groove, and the adjusting bolt passes the mounting disc of lobus sinister sheet and the mounting disc of lobus dexter sheet is screwed onto with nut.。
Be welded with suspension ring on the outer wall of said Blower Housing.
Said blade as the aircraft airfoil vanes, shape in the shape of a spiral.
The beneficial effect of the utility model is:
1, it directly adjusting vane reach the effect of regulating air quantity, make that the adjusting of air quantity becomes simply, convenient, and no longer need specially to provide cost savings for its outfit volume adjusting apparatus.
2, its blade is the same with the aircraft wing blade, shape in the shape of a spiral, and such blade is compared with the blade of traditional axial-flow blower, and its air quantity more strengthens.

Embodiment:
Embodiment: see shown in Fig. 1 to 3 that the ventilator that the leaf angle is adjustable comprises Blower Housing 1, motor 2 and blade 3; Motor 2 is fixed on the inwall of Blower Housing 1, is fixed with block 211 on the main shaft 21 of motor 2, and forms thread section 212 on the said main shaft 21; Said thread section 212 sleeves are in the center hole of lobus sinister sheet mounting disc 5 and lobus dexter sheet mounting disc 4; Mainshaft nut 213 is screwed onto thread section 212, and this mainshaft nut 213 is pressed against on the end face of lobus dexter sheet mounting disc 4, and said lobus sinister sheet mounting disc 5 and lobus dexter sheet mounting disc 4 form left convex tendon respectively and accommodate nest 51 and accommodate nest 41 with right convex tendon; Form convex tendon 31 on the blade 3; This convex tendon 31 is clamped in that left convex tendon is accommodated nest 51 and right convex tendon is accommodated between the nest 41, and said right convex tendon is accommodated on the bottom surface of nest 41 and formed some wedge grooves 411, forms wedge lug 311 on the said convex tendon 31; Wedge lug 311 sleeves are regulated bolt 6 and are passed lobus sinister sheet mounting disc 5 and the mounting disc of lobus dexter sheet 4 and be screwed onto with nut in wedge groove 411.
Be welded with suspension ring 11 on the outer wall of said Blower Housing 1.
Said blade 3 as the aircraft airfoil vanes, shape in the shape of a spiral.
Working principle: the utility model only need be regulated the blade 3 of the utility model when regulating the air quantity size, at first unclamps mainshaft nut 213; Then unclamp and regulate bolt 6, mention blade 3 then, wedge lug 311 is extracted from wedge groove 411; Again blade 3 is rotated angle (the adjustment angle of blade 3 is 10～30 degree) definitely; After rotation puts in place with wedge lug 311 sleeve again at wedge groove 411, after regulate accomplishing, tighten mainshaft nut 213 and regulate bolt 6.
