Abstract

A lifting and locking device for bicycle seat rod and use method thereof comprise a seat tube, an upper seat rod, a lower seat rod, a connecting rod device and a fixing device, wherein that upper seatrod and the lower seat rod are sleeved in the seat tube and are slidably connected with the seat tube in the axial direction, and the top end of the upper seat rod is higher than the top end of the seat tube; The bottom of the upper seat bar is provided with an upper pipe cover, and the top of the lower seat bar is provided with a lower pipe cover. The upper seat bar is provided with a connectingrod device capable of moving along the upper seat bar; The fixing device is connected with the connecting rod device, and is arranged between the upper pipe cover and the lower pipe cover and movablealong the upper seat rod. The fixing device is defined between the upper tube cover and the lower tube cover, and the sleeve is lifted and lowered in the cage by pulling the handle, and finally the deformation completing device of the elastic body is locked. The invention overcomes the problems of poor reliability, complex structure and inconvenient operation of the existing lifting and locking device, and is suitable for various bicycles.

Description

technical field [0001] The invention relates to the technical field of elevating and locking a seat post of a bicycle, in particular to an elevating and locking device for a seat post of a bicycle and a method for using the same. Background technique [0002] At present, common bicycle seat post elevating and locking devices generally rely on the relaxation or contraction of the clip bolts on the bicycle seat tube to change the diameter of the bicycle seat tube to complete the locking function. This method of lifting and locking the bicycle seat post has the following problems: the seat post is easy to rotate around the seat tube when lifting and lowering, so that the position of the seat changes and affects the comfort; The use of easy-slip wires may even break; especially when the bicycle is wet by rain, locking for a long time will easily cause material bonding, making the seat post and seat tube unable to be disengaged, and losing the lifting function.
