Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, with
Lower embodiment combination attached drawing is specifically addressed to provided by the utility model.
Incorporated by reference to Fig. 1 and Fig. 2, a kind of car air-conditioner blast fan is shown, including outer wheel hub 1, inner wheel hub 3 and blade 2,
Outer wheel hub 1 is connected by blade 2 with inner wheel hub 3, and inner wheel hub 3 is equipped with supporting surface 4, and supporting surface 4 is equipped with and machine shaft phase
Mounting base 6 even, under the driving of machine shaft, blast fan can rotation work.Supporting surface 4 is equipped at least two buckles
Component 5, each snap component 5 include be buckled convex block 51 and buckle arm 52, and buckle convex block 51 blocks towards 1 side of outer wheel hub protrusion
It detains and is equipped with a wedge angle 511 close to the side of supporting surface 4 on convex block 51, wedge angle 511 is tilted towards 52 side of buckle arm, mounting base 6
It is equipped with several and 5 matched card slot 61 of snap component.
Using this structure, blast fan is fixedly mounted on by fixture block component in the mounting base 6 being connected with machine shaft,
Installation is close, securely, makes to be not easy to loosen between blast fan and mounting base 6 abnormal sound occurs.
5 more specifical structure of snap component is：Snap component 5 is vertically arranged with supporting surface 4, and setting in this way may be such that card
Buckle assembly 5 is inserted into installation along perpendicular to the direction of mounting base 6；Snap component 5 is connected with 3 side wall of inner wheel hub, and along inner wheel hub 3
It is circumferentially uniformly arranged, ensures that the structural strength of inner wheel hub 3 can be enhanced while firmly installing.It is buckled on convex block 51 close to mounting base
6 side is equipped with a guide bevel 512, and guiding snap component 5 is inserted into along guide bevel 512 in card slot 61 so that install convenient.
Buckle arm 52 is elastic arm, and also inconvenient dismounting while facilitating installation, after installation is complete, the setting of elastic arm may be such that engaging jail
Gu and when dismantling, buckle arm 52 is made into power outside toward 61 notch of card slot, you can snap component 5 and card slot 61 are detached from dismounting.Buckle
The quantity of component 5 can be for 2 or multiple, and the quantity of snap component 5 is 4 in the present embodiment.
61 more specifical structure of card slot is：A bucking ladder 611 is equipped with close to the side of mounting base 6 in card slot 61, it is trapezoidal
Platform 611 is equipped with a trapezoidal inclined plane 612, and trapezoidal inclined plane 612 is matched with guide bevel 512, the insertion of guiding buckle convex block 51；
Re-entrant angle 613 in one is equipped with close to the side of supporting surface 4 in card slot 61, interior re-entrant angle 613 is matched with wedge angle 511, when buckle convex block
51 completely into card slot 61, and interior re-entrant angle 613 just blocks wedge angle 511, and buckle convex block 51 is offseted by 61 inner wall of card slot to be blocked, and is blocked
Buckle assembly 5 is just securely stuck in card slot 61 and is suffered.
Improvement for the structural strength of blast fan in itself：Outer wheel hub 1 is equipped with several shaft orientation reinforcing ribs 7, on blade 2
