Description

Technical Field

[0001] The utility model relates to the technical field of clip springs, in particular to a clip spring with a sealing structure. Background Art

[0002] At present, in the fields of mechanical engineering, automobile manufacturing, aerospace and various precision instruments, the positioning of the shaft and the housing is usually restricted by a retaining spring. The retaining spring can prevent the shaft from axially moving relative to the housing. However, in some usage scenarios that require a sealing function between the housing and the shaft, most retaining springs have no sealing effect. Therefore, it is necessary to provide a sealing ring between the housing and the shaft. However, this is not conducive to realizing multiple functions in one and reducing the number of components. In addition, in order to prevent the sealing ring from shifting, a groove for placing the sealing ring is required on the housing or the shaft, which is more troublesome. In view of the above technical problems, it is necessary to design a retaining spring with a sealing structure, which can not only be used to prevent the shaft from axially moving relative to the housing, but also seal between the shaft and the housing, and the sealing structure is not easy to shift.
