Description

Headset

The present invention relates to a headset headset.

Press, the headset head set that can generally limit the rotation angle of the bicycle head is disclosed in patent TW510336, which includes a lower bead set and a limit ring. Set on the front fork standpipe, the lower bead set is protruded downward with a stopper, and the limit ring is protruded upwardly with two stopper parts, which can be restricted by the stopper being restricted between the two stopper parts The angle of rotation of the head.

However, after the lower bead set is plugged in the head tube and used for a period of time, the structure of the lower bead set is prone to fatigue, or the impact force between the stopper and the stopper is too large, which causes the lower bead set and the head tube to interact with each other. Looseness will cause the front of the car to lose the function of limiting the rotation angle, or the central direction of the rotational range of the front of the car is not aligned with the front of the vehicle body, which has shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive headset to solve the above problems.

The main purpose of the present invention is to provide a headset headset, which can avoid the loss of the function of limiting the rotation angle of the headset, and prevent the center direction of the rotatable range of the headset from being aligned with the front of the vehicle body.

In order to achieve the above object, the present invention provides a headset headgear set for a headset set, the headset set includes a head tube and a front fork standpipe that can be relatively rotatably arranged on the head tube around an axial direction. The headset set includes a first fastening piece and at least one pressing piece. The first fastener is non-rotatably provided on the inner peripheral wall of the head tube, and is provided with at least a resisting structure and a first clamping portion. The at least one pressing member is sleeved on the front fork standpipe and can press against the at least one abutting structure to expand the radial size of the resisting structure. When the first fastening piece rotates with the front fork standpipe At the time, the at least one first latching portion is for interfering with at least one second latching portion disposed on the front fork standpipe.
