Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an upper buckle ring fan structure. Background Art

[0002] Fans are mainly used for cooling and heat dissipation, such as Figure 5 As shown, it is a schematic diagram of an existing fan, which has a bearing and a core shaft. The lower end of the core shaft is in contact with the wear-resistant sheet. An ORING ring 15 is also placed on the wear-resistant sheet. A lower buckle ring 14 is placed on the ORING ring 15. That is, the lower buckle ring 14 is placed below the bearing and is padded by the ORING. The disadvantage is that an extra ORING ring is placed, which increases the cost on the one hand and increases the installation process on the other hand, causing inconvenience in installation.
