Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to an axial flow fan with a quick-disassembly structure. Background Art

[0002] Axial flow fans have a wide range of uses. They can be used for ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil buildings. They can also be used as free fans. They can also be installed in series at intervals in longer exhaust ducts to increase the wind pressure in the duct. In the production of monocrystalline silicon, axial flow fans are needed to dissipate heat from the monocrystalline silicon plant to ensure air circulation inside the plant.

[0003] For example, the patent document with application number 202320749904.9 discloses an axial flow fan. The utility model discloses an axial flow fan, including an axial flow fan body and a connection panel fixedly installed at the lower end of the axial flow fan body. A base is arranged below the connection panel. When the blowing angle of the axial flow fan body needs to be changed, the axial flow fan body is pulled upward, and the adjustment component is pulled by the connection panel. The angle of the axial flow fan body can be changed by setting the adjustment component. During the process of the angle changing, the connection panel will pull the two fixed panels along the base in the horizontal direction by pulling the component. The axial flow fan can achieve the effect of changing the blowing angle of the axial flow fan body while increasing the contact area between the device and the ground, thereby ensuring the stability of the device. However, the axial flow fan. When the axial flow fan needs to be used alone, it must be removed from the upper end of the base.

The advantage of this arrangement is that through the arrangement of the tension spring 204, the sliding clamp 205 can be driven by resetting to clamp and fix the axial flow fan body 3.

[0025] Furthermore, a sliding clamp 205 is provided at the front end of the tension spring 204, and the sliding clamp 205 is slidably connected to the support plate 2 via a sliding groove 202, and a handle 206 is provided on the rear end surface of the sliding clamp 205. The advantage of this arrangement is that, through the arrangement of the sliding clamp 205, the axial flow fan body 3 can be quickly installed to the upper end of the support plate 2 according to the needs of use, thereby improving the installation speed of the axial flow fan body 3 and facilitating use. At the same time, axial flow fan bodies 3 of different sizes can also be clamped, thereby improving the adaptability of the device.

[0026] like Figure 3-Figure 4 As shown, the axial flow fan body 3 is placed on the inner wall surface of the fixing clamp 201, and the upper end surface of the axial flow fan body 3 is provided with a second handle 301.

This is the working principle of the axial flow fan with a quick-release structure.
