Description
本發明係有關於一種車頭碗組。 The present invention relates to a headset headset.
按,一般可限制自行車車頭之轉動角度的車頭碗組係如專利TW510336所揭露,其包含有下珠碗組及限位環,下珠碗組塞設於車頭管之內壁,限位環套設於前叉豎管,下珠碗組朝下凸設有一擋塊,該限位環朝上凸設有二擋止部,藉由該擋塊被限制在二擋止部之間即可限制車頭之轉動角度。 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.
然而,該下珠碗組塞設於車頭管內使用一段時間後下珠碗組容易產生結構疲乏,或是因為擋塊與擋止部之撞擊力道過大,而導致下珠碗組與車頭管相互鬆動,如此即會導致車頭失去限制轉動角度之功能,或是車頭可轉動幅度的中央方向未對齊車身前方,存在亟待改善之缺弊。 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.
因此,有必要提供一種新穎且具有進步性之車頭碗組,以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive headset to solve the above problems.
本發明之主要目的在於提供一種車頭碗組,可避免車頭失去限制轉動角度之功能,以及避免車頭可轉動幅度的中央方向未對齊車身前方。 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.
