Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1-3, the present embodiment is an impeller blade angle rapid detection apparatus, which includes a casing 1 covering an outer portion of an impeller, a positioning hole 11 disposed at a central position of the casing 1, a positioning rod 12 inserted into the positioning hole 11 in an interference fit manner and extending into the casing 1, at least two sets of arc-shaped grooves 13 disposed on two sides of the positioning hole 11 symmetrically and having different diameters and being concentric, and a sleeve 2 inserted into and fitted with the arc-shaped grooves 13.

Casing 1 includes annular lateral wall 14, the top cap 15 that closes annular lateral wall 14 top, and locating hole 11 has been seted up to the central point of top cap 15, and the top of locating lever 12 flushes with top cap 15 and sets up.

And connecting ribs 3 are arranged between the end parts of the two arc-shaped grooves 13 which are correspondingly and symmetrically arranged in each group, and each connecting rib 3 is positioned at the same diameter position.

The peripheral edge of the sleeve 2 is matched with the arc-shaped groove 13 in a copying manner, and the side wall of the sleeve 2 is provided with an avoiding groove 21 of the plug-in connecting rib 3.

Avoidance grooves 21 which are arranged along the axial direction of the sleeve 2 are symmetrically arranged on two sides of the sleeve 2, and the inner ends of the avoidance grooves 21 are arranged in the sleeve 2 and do not penetrate through the sleeve 2. The insertion depth of the avoiding groove 21 is limited at the position of the connecting rib 3.

A portion of the cannula 2 rests on a surface of the housing 1 and another portion of the cannula 2 extends into the interior cavity of the housing 1. The height of each sleeve 2 is the same.

The impeller includes a support member 4, a hollow connection post 41 provided at a central position of the support member 4, and blades 42 provided around a surface of the support member 4. The connecting column 41 is correspondingly matched with the positioning rod 12 in an inserting way, the bottom end of each sleeve 2 is abutted against the angle surface of the blade 42, and a height difference is formed between the top ends of the sleeves 2.
