One first damping positioning body 70, it comprises an axle sleeve 71 and a rubber cushion cover 72, this rubber cushion cover 72 is coated on these axle sleeve 71 outsides and inner side surface exposes trepanning, and this rubber cushion cover 72 is to utilize the formed scrobicular ring ditch 73 of its periphery to be nested in this first installation hole 21 again;
One cross flow fan 60 is to be penetrated one-body moldedly by plastic cement, and its left side is provided with the axle center 61 that a metal is constituted with respect to this axle sleeve 71, and this axle center 61 is to be inserted in this axle sleeve 71, and these cross flow fan 60 right sides are axially arranged with one the 3rd installation hole 62 in addition;
One second damping positioning body 80 is made of and urgent embedding is fixed on the 3rd installation hole 62 of this cross flow fan 60 rubber, and its outside has a flange surface 81, and is axially arranged with one in conjunction with axis hole 82;
One motor 90, its end face are provided with an axle bed 91 and a live axle that protrudes out 92, and are provided with at least one positioning hole 93 in the axle bed both sides; One conjunction base 100, its medial extremity is the junction plane 101 that the body flange 32 of this second installation hole 31 of cooperation is constituted, and outboard end is the external diameter that cooperates this motor 90, being provided with one can be for the ring seat 102 of this motor leading portion embedding, and these junction plane 101 central authorities are with respect to the axle bed 91 of this motor, be provided with one and can embed the trepanning 103 of locating for this axle bed 91, and in the positioning hole 93 of these trepanning 103 peripheries corresponding to this motor, being provided with lockhole 104 can be locked outwardly by the inboard and earlier this conjunction base 100 and motor 90 are mutually combined for screw 105, junction plane 101 with this conjunction base 100 is nested with on this body flange 32 again, and fixed by the outside by screw 106, and the live axle 92 that makes this motor 90 stretch into this second damping positioning body 80 in conjunction with axis hole 82, forming closely, bundle closes state, rotate to drive this cross flow fan 60, constitute a plastic cement system cross flow fan module 200 according to this.
From the above mentioned, because housing 50 of the present utility model is one-body molded, therefore can't fix this motor 90 by right sideboard 30 inner edge surfaces, so, the utility model must use this conjunction base 100 to make up with motor 90 earlier, be fixed on this body flange 32 by outer side surface again, and make the live axle 92 of motor can be accurately and the combining axis hole 82 windings and can drive cross flow fan 60 and rotate of this second damping positioning body 80.
Moreover, between these left and right side plate 20,30 bottom surfaces, be provided with a crosswise fixed plate 52, can be after cross flow fan 60 be installed in housing 50, its two ends utilize a screw 53 to be fixed, and make whole housing 50 more firm.
Again, the front end and back end of these left and right side plate 20,30 bottom surfaces forms a C type groove 56, can a nested buffer rubber gasket 55, and more comprise a foam rubber cushion 54 between former and later two buffer rubber gaskets 55.
Moreover the conjunction base 91 of this motor comprises one with upper lug 108, is locked in for this screw 105 on the post hole 33 of 31 corresponding peripheries of this corresponding second installation hole.
Further, this conjunction base 100 is provided with a plurality of openings 107 for air ventilation with respect to radiation hole 94 places of this motor inboard.
By above-mentioned technological means, be as shown in Figure 8 after the utility model combination, its overall weight is lighter than existing metal fan, but that its composite structure is riveted mode than tinsel is more convenient and intensity is good.Therefore, when cross flow fan 60 rotates with horizontal X-X, although its length L is long slightly, and is also not yielding.When cross flow fan 60 changes with the X-X axle, axle center 61 is supported by these first damping positioning body, 70 axle sleeves 71, and this axle sleeve 71 absorbs received rotating power by the rubber cushion cover 72 that is coated on outer periphery, rotation function is dissolved, so can be reached shockproof effect.And prior design to be this motor 90 be installed in the body flange 32 of this second installation hole 31 by this conjunction base 100 earlier, utilize this live axle 92 to stretch into the second damping positioning body 80 again and drive cross flow fan 60.Because motor 90 is power sources, if the damping design is not good, the vibrations of then will empathizing, or cause very big shake.For this reason, motor 90 of the present utility model utilizes the location of conjunction base 100 earlier, and live axle 92 accurately is positioned on rotational axis x-X, can not produce off-centre, also just is difficult for taking place vibrations or shake.Moreover, not yielding and turn round smooth and easy because of cross flow fan 60, so windage reduces, thereby can reduce that wind is cut and dither noise, so the utility model can be as shown in figure 10, be installed in the control instrument 201 of fitness equipments, and its air-flow is to blow to the user by exhaust outlet 202, also can enjoy cool breeze, the tool practicability in the feasible motion.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
In sum, the utility model is on structural design, use practicability and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicability, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
