Title:
ARBITRARY STOP RESISTANCE TELESCOPIC ROD, AND EQUIPMENT DEVICE AND USE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/111489
Kind Code:
A1
Abstract:
An arbitrary stop resistance telescopic rod, comprising a pull rod (7), shafts (1), friction wheels (17), a housing (6), and a toothed slideway (5). The outer edges of the friction wheels (17) and sections near the outer edges are made of an elastic material, the elastic material can elastically deform under the pressure of the toothed slideway (5), the distance from the outer edge of each friction wheel (17) to a center line of each shaft (1) is greater than the distance from the outer edge of the slideway to the center line of the shaft (1) when no external force acts on the outer edge of the friction wheel (17), and the height h of the tooth shape of the toothed slideway (5) is greater than or equal to 0 and the length L thereof is greater than or equal to 0. The beneficial effects are that the magnitude of the forward and reverse movement resistance of the pull rod (7) can be adjusted by changing toothed corners, the maintenance is easy, and the service life is long. In addition, the present invention further relates to an equipment device provided with the resistance telescopic rod and a use method for the equipment device.
