AI Technical Summary

Technical Problem

Traditional fan blade shaft sleeves lack a positioning structure, resulting in time-consuming and labor-intensive installation, increased assembly costs and difficulty, and a tendency to shift and wobble during operation, thus shortening their service life.

Method used

It adopts a stepped positioning quick-assembly structure. Through the cooperation of trapezoidal positioning blocks and assembly cavity, combined with rubber magnetic blocks, assembly guide rails and locking components, it can achieve fast and accurate alignment and stable connection, reducing offset and shaking.

Benefits of technology

It simplifies the installation process, reduces assembly difficulty and cost, extends the service life of the fan blades and shaft, and improves the stability and wear resistance of the connection.

Abstract

This utility model provides a stepped positioning quick-assembly fan blade sleeve, including a fan blade body, a sleeve body, and a shaft rod. The fan blade body has an installation cavity, and the sleeve body has a sliding mounting component corresponding to the installation cavity. The sleeve body is slidably mounted in the installation cavity via the sliding mounting component and connected by screws. An assembly component is provided on the shaft rod, and the sleeve body also has an assembly cavity. The assembly component passes through the assembly cavity, and a trapezoidal positioning block is provided at one end of the assembly component near the assembly cavity. The periphery of the trapezoidal positioning block contacts the inner side of the assembly cavity. Multiple sets of locking components are also provided on the periphery of the assembly component, and positioning locking holes are provided in the assembly cavity corresponding to the multiple sets of locking components. The locking components pass through the positioning locking holes. The trapezoidal positioning block, rubber magnetic block, assembly slider, assembly guide rail, and locking components cooperate with each other to achieve precise positioning and quick locking of the sleeve, shortening installation time and reducing installation difficulty and cost.
