AI Technical Summary
Technical Problem
The threaded tie rod of the impeller disc of the existing crossflow fan protrudes outside the equipment when using shorter blades, which cannot adapt to the installation space, and the difference in blade width causes uneven airflow.
Method used
It employs telescopic fixing components and adjustable blade assemblies. The distance between the discs is adjusted by extending and retracting the extension rod within the fixing sleeve, and blade assemblies of the same width are used to ensure uniform airflow.
Benefits of technology
This effectively avoids the problem of protruding threaded tie rods, ensures the adaptability of impeller installation space, and ensures the uniformity of airflow at both ends of the impeller, thereby improving the performance of the equipment.

Abstract
The utility model provides a cross flow fan impeller dense type middle disc relates to impeller part technical field. This cross flow fan impeller dense type middle disc, including two disc body, be provided with telescopic fixed assembly between two disc body, and two disc body are fixed through telescopic fixed assembly, and telescopic fixed assembly includes fixed sleeve and extension rod, and fixed sleeve and extension rod are fixedly installed on the side of two disc body close to each other respectively. This cross flow fan impeller dense type middle disc, through setting telescopic fixed assembly between two disc body, utilize the extension rod telescopic in the inside of fixed sleeve, thereby avoided the situation that the threaded pull rod protruded in the both ends of equipment when needing to use shorter blade in prior art, effectively guaranteed the use effect of equipment, and simultaneously through setting the blade assembly of adjustable length, utilize two groups of the same width blade, thereby guaranteed in the actual application process, the airflow outputted in impeller both ends will not exist larger difference, is favorable to the practical application.
