Specific embodiment
Below in conjunction with accompanying drawing 2 to Fig. 6 concrete structure of the present utility model is described:
A kind of improvement type impeller, it is provided with the hub portion 11 of pin-joint part 13 by one and several radial blades 12 that hub portion 11 is provided with constitute impeller 1, other has a magnet ring 3, it is characterized in that: the outer periphery fit at impeller blade 12 is fixed with and the identical fixing frame 2 of impeller blade 12 periphery circularity, and magnet ring 3 fits are fixed on the periphery of circular fixing frame 2.Extremely shown in Figure 6 referring to Fig. 2.
Fixing frame 2 is one to be fixed by the form and impeller 1 fit of single ring body frame, and magnet ring 3 fits are fixed on the periphery of this fixing frame 2.Referring to shown in Figure 2.
The upper end of fixing frame 2 or lower end are provided with the radially ring lip 21 of evagination, and arbitrary end face of the magnet ring 3 that evagination anchor ring and its overcoat of ring lip 21 is solid support is mutually fixed.Referring to shown in Figure 4.
Fixing frame 2 constitutes after by inside and outside two mutual fits of independent ring body frame.Referring to Fig. 5, shown in Figure 6.
The inner ring body frame of fixing frame 2 directly and impeller 1 fit fix, and outer ring body frame 22 fits of fixing frame 2 are fixed on the periphery of inner ring body frame, magnet ring 3 fits are fixed on the periphery of outer ring body frame 22.Referring to shown in Figure 6.
The upper end of outer ring body frame 22 or lower end are provided with the radially ring lip 23 of evagination, and the ring lip of inner ring body frame one end 21 and outer ring body frame 22 set ring lips 23 are symmetricly set on the both ends of the surface of magnet ring 3 each other, and magnet ring 3 clampings are axial betwixt.Referring to Fig. 5, shown in Figure 6.
Inner ring body frame in the fixing frame 2 and impeller 1 are the integrated monolithic construction of plastic cement.Referring to shown in Figure 5.
Below in conjunction with relevant drawings various embodiments' of the present utility model implementation process more specifically and working principle are done further explanation.
See also shown in Figure 2ly, it is first preferred embodiment of the present utility model, and this impeller includes impeller 1, members such as fixing frame 2 and magnet ring 3.
See also shown in Figure 3, it is first a preferred embodiment combination of the present utility model back situation, blade 12 external end edges of this impeller 1 are combined with fixing frame 2, when magnet ring 3 is bonded to the outside of fixing frame 2, because this has bigger area of contact between the two, therefore, this magnet ring 3 also can reach really, firm combination.When this fixing frame 2 was made for metal material, this fixing frame 2 can have preferable poly-magnetic and prevent the magnetic loss effect.
See also shown in Figure 4, it is the utility model second preferred embodiment, on this fixing frame 2 has, the lower end, and be provided with the ring lip 21 of protrusion at least at the one end, therefore, when magnet ring 3 be combined in this fixing frame 2 around the time, this magnet ring 3 is bigger with the area of contact of fixing frame 2, and when especially this ring lip 21 was positioned at the lower end of fixing frame 2 or upper and lower end, this ring lip 21 has more to accept led the locating effect that limits magnet ring 3.
See also shown in Figure 5, it is the utility model the 3rd preferred embodiment, this impeller structure includes impeller 1, members such as fixing frame 2 and magnet ring 3 are formed, its structural type and assembly relation are basic identical with implementing 1, so do not do repetition at this, but have with being exactly that fixing frame 2 in the present embodiment is nested with mutually by inside and outside two ring body frames and constitutes, therefore, inner ring body frame and impeller 1 can penetrate one-body molded with plastic cement, or with tackiness agent gummed, means of fixation such as drive fit are fixed on the external end edge of blade 12.The ring lip 21 that can be provided with protrusion in the upper end or the lower end of this ring frame 2.
Outer ring body frame 22 is to be made by metal material, and these outer ring body frame 22 internal diameters can glue together with tackiness agent, and the mode of being tightly fixed is fixed on inner ring body frame 2 outsides of impeller 1, again and, in the top or the lower end more can be provided with the ring lip 23 of protrusion.
Directly be enclosed within the outside of outer ring body frame 22 by magnet ring 3 internal diameters, because this outer ring body frame 22 is made for metal material, therefore, this magnet ring 3 with promptly can fix therebetween by therebetween suction, again and, if with this magnet ring 3 with its with drive fit mode or coating adhesive fixedly the time, this magnet ring 3 is fixed with it can be more firm.
See also shown in Figure 6ly, it is the utility model the 3rd preferred embodiment combination situations.The inner ring body frame outside of this impeller 1 is combined with outer ring body frame 22, and this frame outside has magnet ring 3.And the size of this outer ring body frame 22 and inner ring body frame, precision can accurately be controlled in the machine shaping process, and therefore, this outer ring body frame 22 combines with inner ring body 2, can reach the strong bonded purpose.Therefore, when magnet ring 3 was combined in the outside of outer ring body frame, this magnet ring 3 increased with the area of contact of outer ring body frame 22, and the ring lip 21,23 of inner ring body frame 2 and outer ring body frame 22 has more and accepts, limits the effect that magnet ring 3 comes off.Again and, when this outer ring body frame 22 was made for metal material, this outer ring body frame 22 can have preferable poly-magnetic and prevent the magnetic loss effect.
Embodiment disclosed in the utility model really can reach desired use effect, its disclosed concrete structure, not only do not seen in the like product, before also not being disclosed in application, anyly be familiar with this operator, in not breaking away from spirit and scope of the present utility model, all can implement, meet the regulation and the requirement of Patent Law fully, the existing application that in accordance with the law proposes utility model patent is earnestly asked and is examined and grant quasi patent.
