Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan installation structure which is easy to assemble and disassemble. Background Art

[0002] A fan is a machine that can rely on input mechanical energy to increase gas pressure and discharge gas. Common fans include ventilators, blowers, wind turbines and centrifugal fans. The installation structure of the fan has a vital impact on the production, use and maintenance of the fan.

[0003] In the existing technology, most of the connections between the various components of the fan may use a variety of connectors of different specifications and types, such as some special latches, complex welding structures or difficult-to-operate riveting methods, etc. This requires professionals to have multiple skills during the installation process, and the operation is difficult and time-consuming. When installing the blower and the chassis, precise welding operations may be required, which not only places high technical requirements on the welding workers, but also easily causes deformation and other problems during the welding process, affecting the installation accuracy and making subsequent adjustments extremely difficult. At the same time, if disassembly and adjustment are required, specific large wrenches or pulling tools may be required, which ordinary maintenance personnel may not be fully equipped with, increasing the difficulty and cost of maintenance. Moreover, different connection methods require different tools. At the actual maintenance or installation site, frequent tool changes will also consume a lot of time, reduce work efficiency, and make operation inconvenient. In view of this, we have introduced a fan installation structure that is easy to assemble and disassemble. Utility Model Content

The bolt A is connected to the surface of the connecting seat, and one end of the bolt A passes through the connecting seat and is connected to the inside of the chassis. The bolt A is used to install the air drum on the surface of the chassis.

[0010] Preferably, a B-shaped retaining spring is connected to the surface of the rotating shaft on one side of the wind wheel, and the provision of the B-shaped retaining spring can fix the wind wheel on the surface of the rotating shaft.

[0011] Preferably, the surface of the wind drum is located on the outside of the wind wheel and is connected to a protective mesh cover, which is used to block larger external objects to prevent external objects from damaging the wind wheel or other components. The surface of the protective mesh cover is evenly spaced with clips, and the clips and the protective mesh cover are integrally formed. The surface of the clip is connected to a bolt C, and the bolt C passes through the bolt C and extends to the interior of the wind drum.

When repairing or replacing the motor or the fan wheel, the components can be quickly removed according to the corresponding disassembly sequence without complicated tools and tedious steps, which greatly improves the maintenance efficiency, reduces equipment downtime, and reduces maintenance costs.

[0014] The mounting slots of the chassis provide preliminary positioning and certain support for the fan drum. Combined with the tightening of bolts A, the fan drum is firmly installed in the chassis. The motor, fixed by the positioning seat and bolts B, can operate stably in the fan drum, ensuring the effective transmission of the motor output power. The axial fixation of the wind wheel by the B-shaped retaining spring and the dual fixation of the protective screen by the buckle and bolts C ensure that all components of the entire fan structure can maintain a stable position relationship during operation, reducing vibration and looseness, extending the service life of the equipment, and improving the reliability of the fan operation.
