Problems solved by technology

However, after the top of the seat tube is cut, in addition to affecting the structural integrity of the seat tube, the top of the seat tube needs to be assembled with the seat cushion through an adapter, which will inevitably affect the connection between the seat tube and the seat cushion. The bonding strength

Embodiment Construction

[0032] Please see first figure 1 , the adjustable seat tube 10 of the present invention includes an outer tube 20 , an inner tube 30 , a lift control valve 40 , and an inner tube adjustment member 50 .

[0033] The outer tube 20 has a tube body 21 , a tube plug 22 and a buffer pad 23 . The pipe plug 22 is disposed on the bottom of the pipe body 21 , and the buffer pad 23 is disposed on the top surface of the pipe plug 22 .

[0034] The inner tube 30 is axially movable through the outer tube 20. The outer peripheral surface of the inner tube 30 has a scale 31. The numbers of the scale 31 are arranged in sequence along the axial direction of the inner tube 30. The top of the inner tube 30 It is located outside the outer tube 20 and has a cushion mounting portion 32 for mounting a cushion (not shown in the figure). The top surface of the cushion mounting portion 32 slopes downward from front to back to form a slope 33 . In addition, the seat cushion mounting portion 32 of the i...

Abstract

An adjustable seat tube comprises an outer tube, an inner tube, a lifting control valve and an inner tube adjusting part. The inner tube is arranged on the outer tube in up-down moving and penetratingmodes. The lifting control valve is arranged between the outer tube and the inner tube and used for controlling the lifting height of the inner tube. The inner tube adjusting part is arranged betweenthe inner tube and the lifting control valve and used for adjusting the displacement of the inner tube relative to the outer tube and the lifting control valve. Through the adjustable seat tube, a rider can adjust the inner tube to a proper length in advance through the inner tube adjusting part, the inner tube can be subjected to subsequent height adjustment through the lifting control valve under the condition that the inner tube is matched with the rider figure, thus, the inner tube does not need to be cut, and the good structural integrality and structure strength of the inner tube are maintained.

Description

technical field [0001] The invention relates to a seat tube of a bicycle, in particular to an adjustable seat tube. Background technique [0002] The height of the seat cushion of the bicycle will affect the comfort and safety of riding, so the current structure will be equipped with an adjustable seat that can adjust the height of the seat cushion according to the rider's body shape, rider's habits and riding environment. Tube, so that the rider can ride in the correct posture, so as to improve riding comfort and safety. [0003] However, due to the size of the seat, even if the height of the seat cushion is adjusted to the lowest level, the seat cushion may still be too high for some particularly short riders, so the more common solution at present is to use the seat tube The top end of the seat tube is cut to shorten the exposed length of the seat tube, allowing riders to adjust the seat cushion to a suitable height according to their body needs. However, after the top ...
