Abstract
The utility model relates to an inducer connection mechanism for a rotating blade type fan, which comprises parts like a synchronous machine, an inducer, a connection bushing, an ornamental ring, etc. The connection bushing is fastened on the axis of the synchronous machine by a cylindrical pin, and the connection bushing is sheathed with the inducer and is provided with a locking device which blocks on the inner plane of the inducer to prevent the axial movement of the inducer. The construction of the utility model is consistent with the requirement of national safety standard for household appliances, and the safety standard is that casing parts of the household appliances can not be discharged without using any tools. The utility model has the characteristics of simple structure, easy assembly and disassembly, etc.
Description
The utility model relates to the installation form of fan inducer, specifically is meant a kind of bindiny mechanism of rotary leaf fan inducer.
The bindiny mechanism of fan inducer of the prior art, mainly comprise synchronous machine, inducer, connect parts such as axle bed, earlier inducer is installed on the connection axle bed with the cross tapping screw during assembling, then the connection axle bed is installed on the axle of synchronous machine tightly.This structure can be under need not the situation of any instrument, as long as inducer is outwards spurred, just can and connect axle bush whole inducer takes out from the axle of synchronous machine, requirement according to national household electric appliance safety standard (GB4706.27-92): under situation not, the housing parts of household electrical appliances can not be unloaded by instrument.Thereby this structure do not meet this standard, has unsafe factor.
The purpose of this utility model be to design a kind of simple in structure, mounting or dismounting are simple and easy and meet the bindiny mechanism of the rotary leaf fan inducer of household electrical appliances safety standard, it can overcome the phenomenon that fan inducer of the prior art just can arbitrarily be dismantled under need not the situation of any instrument, thereby eliminates unsafe factor.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of synchronous machine, inducer of comprising, the bindiny mechanism that connects the rotary leaf fan inducer of axle bush, connecting axle bush is fastened on the axle of synchronous machine by the garden pin, inducer is sleeved on and connects on the axle bush, the locking device retaining that the connection axle bush is provided with is on the inner plane of inducer, to prevent the axial motion of inducer; An end that connects axle bush is equipped with rosette.
The structure of above-mentioned locking device is to have an annular groove on the connection axle bush, and card has a split washer in this annular groove.
After having adopted this structure, when the desire dismounting connects axle bush, must at first rosette be pulled down from an end that connects axle bush, with instrument split washer is pulled down from the annular groove that connects axle bush then, take out inducer again, the garden pin that connect on the axle bush this moment just reveals, and pulls down the garden pin at last and could unload connecting the axle of axle bush from synchronous machine.From above-mentioned unloading process as can be known, the utility model has only adopted a common split washer locking mechanism just can satisfy the requirement of national household electric appliance safety standard, promptly unfavorable with the situation of instrument under can't be installed on the synchronous motor shaft the connection axle bush and on the inducer rosette disassemble, simultaneously it has characteristics such as simple in structure, that mounting or dismounting are simple and easy again.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is an assembling schematic representation of the present utility model
The bindiny mechanism of rotary leaf fan inducer as shown in Figure 1, mainly comprise synchronous machine 1, inducer 2, connect parts such as axle bush 3, rosette 4, connecting axle bush 3 is fastened on the axle of synchronous machine 1 by garden pin 5, inducer 2 is sleeved on by the keyway position 3B on it on key that connects on the axle bush 3, the central position that can guarantee inducer like this.Utilize then to be stuck in to connect that 6 retainings of the split washer on the annular groove 3A are on the inner plane 2A of inducer 2 on the axle bush, to prevent the axial motion of inducer 2, this moment, garden pin 5 was covered by the collar branch of inducer 2.An end that connects axle bush 3 is provided with outside thread, be provided with internal thread in the axis hole of rosette 4, screw on the connection axle bush 3 by the rosette 4 that is threaded, and the outer ring that makes rosette 4 compresses the inner plane 2A of inducer 2, can make rosette 4 like this and be connected axle bush 3 coaxality is preferably arranged, can guarantee the perpendicularity of inducer 2 and synchronous machine 1 again, the more important thing is that this structure can eliminate those and just can arbitrarily disassemble the unsafe factor that is brought to household electric appliance without instrument.
