Description

Technical Field

[0001] The utility model relates to the technical field of industrial fans, in particular to a fan blade chassis mounting mechanism for an industrial fan. Background Art

[0002] Industrial fans are a type of fan that generates powerful airflow by rotating electric and driven spiral blades, thereby improving air quality and working environment. They can usually be placed in two ways: vertically and horizontally.

[0003] According to the Chinese patent publication number CN220378504U, "A fan blade chassis installation mechanism for industrial fans", it mainly describes the connection relationship between the fan chassis, the fixed card seat, the tooth plate and the fan blades. The plug-in connection method is more stable than the traditional connection method, and a reinforcement plate is provided between adjacent fan blades to further strengthen the fan blades. A section of steel cable is reserved at the end of the fan blade close to the fan chassis. After the whole is assembled, the reserved steel cable and the fan chassis are locked with hardware without affecting normal operation. This can further prevent the plug-in connecting the fan blade and the fan chassis from breaking, and then causing the fan blade to fall off and hit the machine or personnel. In this process, the fan blade chassis needs to adjust the rotation diameter of the fan blade after the hoisting is completed, which is prone to poor stability during installation.

[0004] Therefore, a fan blade chassis mounting mechanism for an industrial fan is proposed to solve the problem that the rotation diameter of the fan blades needs to be adjusted after the fan blade chassis is hoisted, which easily leads to poor stability during installation. Utility Model Content

[0007] As a preferred technical solution of the utility model, the rotating block is located in the fixed sleeve and is fixedly connected with an insertion rod, and the insertion rod is movably connected to the reinforcing rib. By arranging the insertion rod and the reinforcing rib, the stability of the blade rotation can be increased.

[0008] As a preferred technical solution of the utility model, a spring is sleeved on the insertion rod, and the two ends of the spring are respectively in contact with the moving block and the rotating block. By arranging the insertion rod and the spring, the moving block can be further limited.

[0009] As a preferred technical solution of the utility model, one side of the reinforcing rib is in contact with a ball, and the ball is rotatably embedded in the fixing sleeve. By providing the ball, the friction of the movement of the reinforcing rib is reduced.
