Abstract
The utility model discloses a centrifugal fan passes through wind wheel structure, including wind wheel main part piece, the lateral wall punching press of wind wheel main part piece is formed integrally with a plurality of wind wheel blade, wind wheel blade keeps away from one side of wind wheel main part piece is provided with the closing cap piece, the terminal surface of closing cap piece seted up with wind wheel blade male recess, wind wheel blade inserts the recess is rolling over a wind wheel blade. The wind wheel main body piece and the wind wheel blades are integrally formed by punching, one side of each wind wheel blade is inserted into the groove of the sealing cover piece, and therefore the wind wheel blades are convenient to assemble, rapid and convenient to use, low in cost and prevented from falling off.
Description
Technical Field
The utility model relates to a fan technical field specifically is a centrifugal fan passes through wind wheel structure.
Background
The centrifugal fan is a machine which increases gas pressure and discharges gas by means of input mechanical energy, accelerates the gas by using an impeller rotating at a high speed according to the principle that kinetic energy is converted into potential energy, then decelerates and changes the flow direction, so that the kinetic energy is converted into the potential energy, and the centrifugal fan is widely used for ventilation, dust discharge and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, cooling and ventilation in air conditioning equipment and household electrical equipment, and the like.
However, the centrifugal fan through wind wheel is formed by folding the two sides of the wind wheel blades after the wind wheel blades are inserted into the wind wheel main body sheet and the sealing cover sheet, and is not integrally formed by punching, so that the wind wheel blades are easy to fall off when being used for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a centrifugal fan passes through wind wheel structure to solve present centrifugal fan and pass through the wind wheel and fold wind wheel blade both sides through injecting wind wheel main part piece and cover plate after, not punching press integrative formation, in the longer term of live time, the problem that drops easily.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a centrifugal fan passes through wind wheel structure, includes wind wheel main part piece, the lateral wall punching press of wind wheel main part piece is formed integrally with a plurality of wind wheel blade, wind wheel blade keeps away from one side of wind wheel main part piece is provided with the cover plate, the terminal surface of cover plate seted up with wind wheel blade male recess, wind wheel blade inserts the recess is turning over a wind wheel blade.
Furthermore, a rotating shaft sleeve hole for installing a motor shaft is formed in the middle of the wind wheel main body piece.
Further, the wind wheel blades are equal in length and parallel to each other, and an airflow channel is formed between the two parallel wind wheel blades.
Further, the wind wheel blades are of arc-shaped structures.
Further, the wind wheel main body piece with the cover plate is circular structure.
Compared with the prior art, the beneficial effects of the utility model are that:
this centrifugal fan passes through wind wheel structure, and it is punching press integrated into one piece between wind wheel main part piece and the wind wheel blade to in one side of wind wheel blade injects the recess of closing cap piece, and then convenient equipment, and swift convenient, less cost prevents to drop.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a centrifugal fan passes through wind wheel structure, includes wind wheel main part piece 1, and the lateral wall punching press of wind wheel main part piece 1 is formed integrally with a plurality of wind wheel blade 2, and one side that wind wheel blade 2 kept away from wind wheel main part piece 1 is provided with the closing cap piece 3, and the terminal surface of closing cap piece 3 is seted up with wind wheel blade 2 male recess 31, and wind wheel blade 2 inserts recess 31 and is turning over a wind wheel blade 2.
In this embodiment, this centrifugal fan passes through wind wheel structure, and it is punching press integrated into one piece between wind wheel main part piece 1 and the wind wheel blade 2 to in one side of wind wheel blade 2 injects the recess of closing cap piece 3, and then convenient equipment, and swift convenient, less cost prevents to drop.
The middle part of wind wheel main part piece 1 is seted up and is used for installing the pivot cover hole 4 of motor shaft, is used for connecting the motor shaft through pivot cover hole 4, drives the wind wheel and rotates.
The wind wheel blades 2 are equal in length and parallel to each other, an airflow channel is formed between the two parallel wind wheel blades 2, and airflow is transmitted through each airflow channel.
To sum up, this centrifugal fan passes through wind wheel structure, and it is punching press integrated into one piece between wind wheel main part piece 1 and the wind wheel blade 2 to in one side of wind wheel blade 2 injects the recess of closing cap piece 3, and then convenient equipment, and swift convenient, less cost prevents to drop.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
