Title:
LOWER RUNNER POSITIONING STRUCTURE WITHOUT FLEXIBLE SECTION
Document Type and Number:
WIPO Patent Application WO/2018/001009
Kind Code:
A1
Abstract:
A lower runner positioning structure without flexible section. An engaging ring (30) is fixedly provided at a fixed position on a shaft (10) corresponding to a lower runner (20). The lower part of the lower runner (20) is provided with a bushing (21). An embedded groove (22) is formed on the inner wall of the bushing (21). The edge of the embedded groove (22) forms an oblique surface (23) for guiding the entry of the engaging ring (30). When the engaging ring (30) slides into the embedded groove (22), the lower runner (20) is positioned on the shaft (10). The present structure is simple, an open groove is provided on the shaft (10), and the shaft (10) is of increased strength; the engaging ring (30) is convenient and quick to mount, thus saving time and effort; and the engaging ring (30) on the shaft (10) neither scratches the fingers nor hooks onto clothing, thus improving safety.
