Description
Technical field
This utility model relates to Fan Equipment field, particularly relates to a kind of petal type air quantity and regulates door.
Background technology
It is the device for regulating fan delivery and wind speed that the air quantity of blower fan regulates door, it is that one of which uses relatively broad and ripe product that petal type air quantity regulates door, it includes the rotatable blade composition of polylith, realize regulating the opening and closing of door by controlling the rotation of blade, and then reach to regulate the purpose of air quantity.But the mounting means of existing adjustment door Leaf, usually all fix corresponding rotating shaft in the bottom of blade and top, and so that the axis of rotating shaft can with the center line conllinear of blade, so that the more convenient rotation of blade, the mode being usually taken is to arrange draw-in groove in rotating shaft, then blade is stuck in draw-in groove and is attached, for instance application number is a kind of mode disclosed in the utility model patent of 201220116435.9.But, this kind of mode needs to arrange draw-in groove in rotating shaft, and its course of processing is cumbersome；Additionally blade is originally as one layer of thin-slab structure, and its structural strength is poor.
Utility model content
This utility model solves the technical problem that being to provide a kind of new petal type air quantity solving the problems referred to above regulates door.
This utility model solves the technical scheme is that petal type air quantity of its technical problem and regulates door, including air duct, tap web body, support bar, blade and adjustment turning collar, described tap web body is positioned at the center of air duct, one end of described support bar is connected with tap web body, its other end is connected with air duct, described blade has multi-disc, more blades is along the circumferentially-spaced arrangement of air duct, the bottom of blade is fixedly installed the bearing pin being rotatably connected with tap web body, and the top of blade is fixedly installed through air duct and the driving axle that is rotatably connected with air duct；Coaxial with the bearing pin on a piece of blade and driving axle, and the center line conllinear of the axis of the two and blade；Drive and axle is flexibly connected with the adjustment turning collar being enclosed within air duct by driving member through one end of air duct, and driving axle axial rotation can be driven by rotating adjustment turning collar, it is respectively provided with fluted in the bottom of blade and top, and bearing pin and driving axle are placed in the groove of correspondence.
Further: the through connection of groove of blade bottom end and top end.
Further: the cross section semicircular in shape of described groove.
Further: described groove is punch forming.
Further: described bearing pin and drive the size of axle and groove to match, and bearing pin and drive axle and groove to be welded to connect.
The beneficial effects of the utility model are: by arranging groove structure in the bottom of blade and top, and by the groove being arranged on correspondence coaxial to bearing pin and driving axle, so can realize bearing pin and drive the center line conllinear of axle and blade, simultaneously without arranging notch on bearing pin and driving axle.And by by the through connection of groove of blade bottom end and top end, the structural strength of blade also can be improved.

Figure is labeled as: air duct 1, tap web body 2, support bar 3, blade 4, adjustment turning collar 5, bearing pin 6, driving axle 7, groove 8, driving member 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Shown in as shown in Figure 1 to Figure 4, petal type air quantity described in the utility model regulates door, including air duct 1, tap web body 2, support bar 3, blade 4 and adjustment turning collar 5, described tap web body 2 is positioned at the center of air duct 1, one end of described support bar 3 is connected with tap web body 2, its other end is connected with air duct 1, described blade 4 has multi-disc, more blades 4 is along the circumferentially-spaced arrangement of air duct, the bottom of blade 4 is fixedly installed the bearing pin 6 being rotatably connected with tap web body 2, and the top of blade 4 is fixedly installed through air duct 1 and the driving axle 7 that is rotatably connected with air duct 1；Coaxial with the bearing pin 6 on a piece of blade 4 and driving axle 7, and the center line conllinear of the axis of the two and blade 4；Drive and axle 7 is flexibly connected with the adjustment turning collar 5 being enclosed within air duct 1 by driving member 9 through one end of air duct 1, and driving axle 7 axial rotation can be driven by rotating adjustment turning collar 5, it is respectively provided with fluted 8 in the bottom of blade 4 and top, and bearing pin 6 and driving axle 7 are placed in the groove 8 of correspondence.
The operation principle regulating door in this utility model is similar to of the prior art, external force control to rotate and regulate turning collar 5 and rotate, and drives axle 7 axial rotation by driving member 9, and then band moving vane 4 rotates, it is achieved what regulate door is turned on or off operation.
Wherein, arrange on blade 4 groove 8 in order that be easy to bearing pin 6 and drive axle 7 to be fixedly installed in groove 8, so can meet bearing pin 6 and drive the axis of axle 7 and the center line conllinear of blade 4, simultaneously again without arranging inserting slot construction on bearing pin 6 or driving axle 7.It addition, also can by the through connection of groove 8 of blade 4 bottom and top end, now bearing pin 6 and driving 7 need of axle are installed to the two ends of groove 8；Such benefit is can to pass through groove 8 to improve the structural strength of blade 4 further.
General, it is contemplated that bearing pin 6 and the driving generally cylindrical body structure of axle 7, therefore the cross section of groove 8 can be arranged the structure of semicircular in shape, in order to bearing pin 6 and the size and the form fit that drive axle 7, bearing pin 6 of being more convenient for is fixed with the installation driving axle 7.It addition, be fixed on the concrete mode in groove 8 for bearing pin 6 and driving axle 7, the mode that such as bolt connects or directly welds can be adopted.
Can adopting punch forming mode for the formation of groove 8 in this utility model, its processing mode is simple, good forming effect.
