Embodiment Construction

[0060] First please refer to Figure 1 to Figure 5 As shown, the height adjustment wire-controlled structure of a bicycle seat tube provided by the present invention mainly includes: a seat tube group 10 arranged in a bicycle seat tube 51, and a bicycle seat tube group 10 arranged in a bicycle seat tube. The brake-by-wire group 20 at the preset position of the frame 52 and a lever return group 30 arranged between each of the seat cushion riser groups 10 and the brake-by-wire group.

[0061] The seat cushion standpipe group 10 has an outer tube 11 and an inner tube 12 that are sheathed with each other. The inner tube 12 can be displaced in the outer tube 11 to have a height change; the inner tube 12 is provided with a The valve block 13 is a valve stem 131 that can be linearly displaced, one end of which controls the opening and closing of the hydraulic oil path, and the other end of the valve stem 131 extends toward the bottom of the outer tube 11; an extension section 111 is ...

Abstract

A seat stem adjustment device includes a seat stem received in an outer tube, a control unit connected to a bicycle frame, and a leverage unit located between the outer tube and the control unit. The control unit has a cable which is connected to and driven by a lever. The leverage unit has a top member connected to the outer tube. A first link and a second link are pivotably connected to the top member. The first link contacts the valve rod. The second link has a mediate portion pivotably connected to the top member. The second link is connected to the cable. A resilient member is connected between the top member and the second link. The second link pushes the first link to open or close the hydraulic liquid path when the cable is operated so as to adjust the height of the seat.

Description

technical field [0001] The invention relates to a lever-type wire control structure, especially a height adjustment structure used in air-hydraulic seat cushions, in order to reduce stuck situations, improve the effect of smooth wire control actions, and provide convenient assembly And the bicycle seat cushion standpipe height adjustment wire control structure with stable and effective functions. Background technique [0002] The seat tube of the bicycle is mainly assembled in the seat tube of the bicycle as the medium between the frame and the seat cushion. If the length of the seat tube exposed to the bicycle seat tube is changed, the height of the seat cushion can be further adjusted. With ergonomic design. [0003] Seat riser technology applications with seat height adjustment are common in the market at present, which can be roughly classified into three types: "hydraulic type", "air-oil hydraulic hybrid type" and "mechanical type". Among them, "hydraulic type" is used...
