Problems solved by technology

[0003] 1. Inconvenient assembly and maintenance of components
Because the oil circuit exchange of the lifting adjustment unit is applied to the internal space of the inner and outer tubes, when the components fail to be replaced, the entire internal components of the support tube need to be disassembled, which makes maintenance inconvenient and relatively inconvenient in assembly
[0004] 2. The oil circuit ring for oil retaining is easy to break or wear
However, when adjusting the lowering height of the seat cushion, when a person sits on the seat cushion, there will be a huge momentary downward pressure on the seat tube. The oil ring bears the shear

Embodiment Construction

[0038] see Figure 1-3 As shown, the bicycle seat tube height adjustment mechanism 1 of the embodiment of the present invention includes an outer tube 10 , an inner tube 20 , a lift adjustment unit 30 , and a lift control unit 40 . in,

[0039] This outer pipe 10, the bottom end penetrates in the standpipe of a bicycle frame and is fixed with this standpipe. There is a joint tooth surface 11 on the inner wall of the bottom end, and a head 12 is connected to the outer wall of the top end.

[0040] The bottom end of the inner tube 20 penetrates into the outer tube 10 from the top end of the outer tube 10, and a fixing seat 21 is arranged at the top end, and the fixing seat 21 is used to fix a cushion for riding a bicycle.

[0041]The lift adjustment unit 30 is passed through the combined interior of the inner and outer tubes 20 and 10 . It includes a first tube 31 and a second tube 32 passing through the first tube 31 , the length of the second tube 32 is shorter than that of...

Abstract

The invention provides a bicycle seat tube height adjusting mechanism. Mainly, oil way switches of the bicycle seat tube height adjusting mechanism are all located in a lifting adjusting unit, and valve ports of the oil way switches and an oil baffle are jointed in a vertical attachment mode for blockage. Thus, during maintenance, it is only needed to pull and replace the lifting adjusting unit, and the effects of being convenient to maintain and assemble are achieved. The valve ports and the oil baffle are in surface attachment in the vertical setting relationship, the oil baffle effect is good, at the moment a user sits on a seat cushion, the oil baffle does not bear shear force, and therefore the service life is prolonged.

Description

【Technical field】 [0001] The invention relates to a bicycle seat tube height adjustment mechanism, especially the bicycle seat tube height adjustment mechanism which has the advantages of convenient assembly and maintenance, simplified components and easy processing, and novel structure. 【Background technique】 [0002] The known bicycle seat tube height adjustment mechanism is mostly composed of an inner tube, an outer tube, a lifting adjustment unit and a lifting control unit. Wherein, one end of the inner tube and the outer tube are inserted into each other. The lifting adjustment unit is located in the inner and outer tubes, one end is fixedly connected to the outer tube, and the other end is fixed to the inner tube to drive the inner tube to rise or fall. The lift control unit is operated by a user to control the action or stop of the lift adjustment unit. Such as China Taiwan patent application case number: 104205140, 099137166 etc. (hereinafter referred to as the kno...
