Abstract
The utility model discloses a novel static impeller. The novel static impeller comprises a base plate. A central punch hole is formed in the middle of the base plate, and protruding columns are arranged on the two sides of the central punch hole. Wind guide blades are arranged on the periphery of the base plate and distributed on the base plate in a spiral mode in the peripheral direction. The centers of the bottom circles of the protruding columns and the circle center of the central punch hole are on the same straight line. Each protruding column is composed of an upper cylinder and a lower cylinder, and the diameter of the lower cylinders is larger than that of the upper cylinders. When a metal frame is connected with the static impeller, the protruding columns can be directly in interference fit with screw holes of the metal frame, the step that operation workers need to lock screws one by one is replaced, the production efficiency is improved, use of the labor force is reduced, and the manufacturing cost of products is lowered.
Description
Technical field
The utility model relates to motor of dust collector technical field, particularly a kind of novel impeller of determining.
Background technique
The motor of dust collector of P82 series in the market, determine impeller and by screw, lock in turn connection with needing operator being connected of metal frame, motor, in the process of batch production, has not only increased labour force's input like this, and the use that reduces manufacturing efficiency and a large amount of screws has increased manufacture cost.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of novel impeller of determining.
Technical solutions of the utility model are as follows:
Novelly determine an impeller, comprise substrate, the centre of described substrate is provided with central hole, and the both sides of described central hole are respectively provided with projection, the outer guide vane that is arranged with of described substrate, and described guide vane is laid on substrate in the shape of a spiral by circumferencial direction.
The round heart in the end of described projection and the center of circle of central hole are point-blank.
The shape of described projection consists of upper and lower two cylinders, and lower body diameter is greater than body diameter.
The beneficial effects of the utility model are, (1) in metal frame when determining impeller and be connected, directly by projection and metal frame screw hole, carry out slight interference and coordinate, replaced operator's step of screw lock in turn, improve manufacturing efficiency, reduced the fabricating cost of labour force and product.
