Document Type and Number:
WIPO Patent Application WO/2022/099799
Kind Code:
A1
Abstract:
A telescopic support and an electric hair dryer apparatus using same. The telescopic support comprises at least two stages of sleeves; each stage of sleeve is provided with a longitudinal sliding guide portion that is located on an outer surface and/or an inner surface; the longitudinal sliding guide portion provided on the outer surface of a previous-stage sleeve cooperates with the corresponding longitudinal sliding guide portion provided on the inner surface of a next-stage sleeve, so that the longitudinal sliding guide portions can linearly slide relative to each other; each stage of sleeve is provided with an outer diameter adapter located on the outer surface near a lower end and/or an inner diameter adapter located on the inner surface near an upper end; the maximum outer diameter of the position of the previous-stage sleeve where the outer diameter adapter is provided is basically equal to the minimum inner diameter of the position of the next-stage sleeve where the inner diameter adapter is provided; and the outer diameter adapter of the previous-stage sleeve and the inner diameter adapter of the next-stage sleeve both are provided with engagement pairing portions that engage with each other in a longitudinal direction. The telescopic support is good in locking performance, and is particularly suitable for being used as a support for heavy objects, such as an electric hair dryer.
