Axial flow fan convenient to install and adjust

Abstract

The invention provides an axial flow fan which is easy to install and adjust, including fan blades and wind guide rings, the fan blades have a mounting end, the mounting end has a motor, and the motor has a mounting frame. The inner shaped strip cavity of the wind guide ring, the upper and lower ends of the cavity form ring-shaped fixed sides respectively, the mounting frame includes a mounting seat, and an mounting cavity is formed in the middle of the mounting seat, and the mounting cavity is used for installing Fixing the motor; a plurality of equally spaced extension plates are arranged on the peripheral edge of the mounting seat, the end of the extension plate is provided with a positioning bar extending vertically upward, and the end of the positioning bar has a horizontally extending outward The fixed strip has a fixed plate at the end of the fixed strip; an annular groove is formed on the upper end surface of the annular fixed edge, the fixed plate is matched with the annular groove, and the fixed plate is arc-shaped. The invention can solve the problems existing in the prior art, improves the installation structure between the fan and the wind guide ring, is convenient and flexible to install, and can improve the strength of the overall connection structure.

Description

technical field [0001] The invention relates to the field of fan equipment, in particular to an axial flow fan which is convenient for installation and adjustment. Background technique [0002] Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements, such as: general factories, warehouses, offices, residences, etc. Axial flow fans are fixed on the wall or roof to allow the air to move axially for indoor Ventilation and ventilation. Axial flow fans will accumulate more dust on the fan blades due to long-term use. More dust will easily increase the load on the motor and reduce the ventilation effect. Therefore, people need to clean and maintain the axial flow fans, but currently on the market It is inconvenient to install between the fan blades and the wind guide ring on the axial flow fan, and the structure is not strong enough, which needs to be improved to meet the needs of the existing market.

[0002] Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements, such as: general factories, warehouses, offices, residences, etc. Axial flow fans are fixed on the wall or roof to allow the air to move axially for indoor For ventilation and ventilation, the axial flow fan will accumulate more dust on the fan blades due to long-term use. More dust will easily increase the load on the motor and reduce the ventilation effect. Therefore, people need to clean and maintain the axial flow fan, but currently on the market It is inconvenient to install between the fan blade and the wind guide ring on the axial flow fan, and the structure is not strong enough, which needs to be improved to meet the needs of the existing market
