An easy-to-install fan

Abstract

The invention discloses an easy-to-install fan, comprising a frame, the back of the frame is clipped with louvers, the front of the frame is fixed with a protective net through bolts, and the inside of the frame is connected with fan blades through a belt drive. The fan blades are connected through a driving motor. In the present invention, the overall stability can be ensured by directly welding the lower ends of the supporting legs to the top of the connecting plate, and the connection between the connecting plate and the supporting seat is fastened through the first positioning plate and the second positioning plate, because the first positioning plate It is welded with the second positioning plate so that there will be no separation between the two. At the same time, the end of the connecting plate inside the fixed frame is limited and fastened by two fastening plates, which can prevent the middle part of the connecting plate from shaking, thus affecting the fan. Stability during work, this kind of connection is more firm, reduces the vibration generated by the fan when it is working, and further prolongs the service life of the fan.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan that is easy to install. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The fan is the abbreviation of China's habit of gas compression and gas delivery machinery. Usually, the so-called fan includes ventilator, blower ,Wind Turbines. [0003] Gas compression and gas delivery machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports the gas out. The main structural components of the fan are the impeller, casing, air inlet, bracket, motor, pulley, and coupling , mufflers, transmission parts (bearings), etc. The unpowered ventilator uses the natural wind and the air heat convection caused by the temperature difference between indoor and outdoor to drive the turbine to rotate, so that th...

Problems solved by technology

[0006] However, the existing fan bases are simply connected by bolts during installation. Although the installation is relatively simple, the fan itself will inevitably vibrate during long-term use. Because there is a gap between the bolts on the base after installation, it will vibrate for a long time It will cause the bolts to loosen and fall off from the base. In severe cases, it will cause damage to the fan and reduce the service life of the fan
