Abstract
The utility model discloses a fan impeller easy to assemble. The fan impeller comprises a middle disc, a circular cover plate, and peripherally distributed blades connected between the middle disc and the circular cover plate. The middle disc and the circular cover plate are provided with holes evenly spaced and distributed on the blade mounting periphery. Two ends of each blade are provided with protruding inserts which are inserted into the holes, and the inserts are bent into press heads, and the middle disc and the circular cover plate are locked by the press heads and the blades. During assembly of the fan impeller, the blades can be connected with the middle disc and the circular cover plate only by inserting the inserts of the blades into the holes on the middle disc and the circular cover plate and bending the inserts; and the fan impeller has the advantages of convenience in assembly and higher production efficiency.
Description
Technical field
The utility model belongs to the blower fan technical field, relates in particular to a kind of impeller of blower fan.
Background technique
Blower fan is the critical component in ventilation equipment or the ventilation system.Blower fan usually by spiral case, be located at impeller in the spiral case and the motor of drives impeller constitutes.Wherein, draught fan impeller by mid-game, ring-like cover plate and be connected mid-game and ring-like cover plate between circumferential blade constitute.
In the prior art, being connected between the blade of draught fan impeller and mid-game and the ring-like cover plate is that the mode operation easier of welding is big, and inefficiency by the mode of welding.
In addition, for realizing being connected with the live axle of motor, has reel at the center of mid-game.The reel volume ratio is less and smooth, and pinch can't the application of force with holding, when blower fan assembles, workman's hand can only grasp other parts of blower fan, but owing in the mini fan impeller, no matter be mid-game, ring-like cover plate, or blade, all be to adopt sheeting material to make, therefore, in the assembly process, the necessary extreme care of workman, the person can not make and impeller generation deformation cause quality of product to go wrong.
The model utility content
For this reason, technical problem to be solved in the utility model provides a kind of draught fan impeller convenient for assembly, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of draught fan impeller convenient for assembly, its include mid-game, ring-like cover plate and be connected mid-game and ring-like cover plate between circumferential blade, it is characterized in that: described mid-game and ring-like cover plate evenly are intervally distributed with jack at blade mounting point circumference, the two end part of described blade have outstanding plug, described plug inserts in the described jack and the bending back forms pressure head, and the end of described pressure head and described blade tightens described mid-game and ring-like cover plate.
Described plug is positioned at the neutral position of the end of described blade.
For the plug that makes things convenient for blade can insert described jack easily, the top of described plug is semicircle, and described jack centre is wide, two is narrow.
Adopt technique scheme, only need the plug of blade is inserted the jack of mid-game and ring-like cover plate when assembling, the plug that bends then just can be realized being connected of blade and mid-game and ring-like cover plate, have easy to assembly, the advantage of enhancing productivity.
In addition, the central position of described mid-game is connected with reel, for the sheet material of realizing not grasping impeller just can grasp impeller and can the application of force, avoids causing the distortion of impeller, has groove on the circumferential surface of described reel.
Be convenient processing, described groove is the circular groove along the circumference extension of reel.
In addition, have pin-and-hole in the described circular groove, also be provided with pivot pin in the described pin-and-hole.Pivot pin is used for pressing closer the axle of motor, realizes that the axle of reel and motor is fastenedly connected.
Description of drawings
Below in conjunction with accompanying drawing and concrete enforcement the utility model is elaborated:
Fig. 1 is the novel structural representation of the utility model;
Fig. 2 is the side schematic view of Fig. 1.
Fig. 3 is the structural representation of mid-game;
Fig. 4 is ring-like structure of cover plate schematic representation;
Fig. 5 is the structural representation of blade;
Fig. 6 is the structure of reel.
Among the figure:
The 100-mid-game, the 101-center hole, the ring-like cover plate of 200-, the 300-blade, the 400-reel, 401-end face, 403-prolong ring limit, 404-crimping, 500-circular groove, 601-pin-and-hole, 602-bearing pin, 701-jack, 702-plug, 703-pressure head.
Embodiment
As depicted in figs. 1 and 2, draught fan impeller convenient for assembly of the present utility model, its include mid-game 100, ring-like cover plate 200 and be connected mid-game and ring-like cover plate 200 between circumferential blade 300.Be connected with reel 400 at mid-game 300 internal surface centers.
As shown in Figure 3 and Figure 4, be distributed with jack 701 in mid-game 100 with the position circle weekly interval that ring-like cover plate 200 is positioned at the blade 300 that is connected, the centre of jack 701 is wide, and two is narrow.As shown in Figure 5, have outstanding plug 702 in the neutral position at the two end part of blade 300, the top of plug 702 is semicircle.
In conjunction with shown in Figure 1, when blade 300 is connected with ring-like cover plate 200 with mid-game 100, be that plug 702 with blade 300 inserts in the jack 701 of mid-games 100 and ring-like cover plate 200, then plug is bent, the surface that is attached to mid-game 100 and ring-like cover plate 200 forms pressure head 703, and pressure head 703 tightens mid-game 100 and ring-like cover plate 200 with the end of blade 300.
As shown in Figure 7, for the sheet material of realizing not grasping impeller just can grasp impeller and can the application of force, reel 400 has along the circular groove 500 of circumference extension at circumferential surface, has pin-and-hole 601 in this circular groove 500, be provided with pivot pin 602 in the pin-and-hole 601, this pivot pin 602 is used for holding out against the axle of motor.
The utility model only needs the plug of blade is inserted the jack of mid-game and ring-like cover plate, the plug that bends then just can realize being connected of blade and mid-game and ring-like cover plate in when assembling, have easy to assembly, the advantage of enhancing productivity.In addition, the utility model also has by grasping the advantage that the reel application of force does not cause the impeller distortion.
