具体实施方式
请参阅图3及图4,是本实用新型第一较佳实施例所提供的一种C形扣20,其包含有:一呈C形的环身30以及两个开孔40。该环身30具有可开合的弹性,且具有相向的两端32。该C形扣20的两端32定义为C形扣的前侧。该环身30是左右对称的构形,具有两侧。一开口34,形成于该两端32之间。由于该环身30具有可开合的弹性,因此可改变该C形扣20的外径。
该两开孔40设于该环身30的外周缘,分别位于该环身两侧,且呈对称设置。开孔40的位置可设于该环身30的两端32之处,或如图3所示,临近该环身30的两端,自该两开孔40施予向内的作用力时,可改变该环身30的外径。
各该开孔40具有一连通口42与一封闭端44,本较佳实施例的该两开孔40设于环身30的外周缘,因此,各该连通口42连通该环身30的外周缘。本说明书定义,连通口42的位置为开孔40的外侧。该封闭端44具有一内侧壁45及一外侧壁46,分别位于该开孔40的内、外侧,连接该连通口42与该封闭端44的该外侧壁46形成一挡止边缘,可防止扣环钳脱出开孔40(将于下文说明)。
本实施例的C形扣20为内扣式的扣件,可缩小外径,该封闭端44的位置较该连通口42的中心靠近C形扣的前侧,所述的连通口42的中心是指连通口42的宽度的中央。
请参阅图4,该两开孔40可斜向地设于该环身30上,所述的斜向指界于环身30的切线方向T与法线方向N之间的方向。该两开孔40大致上沿着向内的作用力的方向设于该环身30。该连通口42与封闭端44之间的连线形成该开孔40的纵向L,该纵向L界于该切线方向T与法线方向N之间。于本较佳实施例,各开孔40的连通口42往封闭端44的设置方向是由C形扣20的后侧往C形扣的前侧设置。
此外,该环身30于本较佳实施例具有一致的宽度W,惟实施上不以此为必要;两窄部36,设于该环身30的两侧,为宽度较窄的部位,该两窄部36分别临近该两开孔40,且位于该两开孔的后侧。本实施例于环身30的两侧的周缘各至少凹设一凹入38,以形成各该窄部36。该两窄部36使C形扣20更容易弹性变形。
使用时,如图5、图6所示,以一扣环钳50的钳嘴的两尖端52分别伸入该C形扣20的该两开孔40并施力,可改变该C形扣的外径。请参阅图7,该两尖端52施予向内夹压的作用力时,可使该环身30的外径缩小,进而可将该C形扣20移入一对象的内孔中,例如图8所示的套筒60的内孔62中,释放该作用力后,该C形扣20弹性回复,并扣入该内孔62的环槽64。
如图7所示,当该扣环钳50缩小该C形扣20的外径时,扣环钳的尖端52受开孔40的挡止边缘(即该外侧壁46)挡止,无法脱出开孔40,可确保扣环钳50夹压C形扣20的过程中,尖端52不会脱离C形扣20。
请参阅图9及图10,是本实用新型第二较佳实施例所提供的C形扣20’,相同的构件沿用相同的标号。该C形扣20’同样包含有:一呈C形的环身30以及两开孔40’。该环身30具有可开合的弹性,且具有两端32。该C形扣20’的两端32为C形扣的前侧。一开口34,形成于该两端32之间。
该两开孔40’设于该环身30的内周缘,分别位于该环身两侧,同样的,开孔40’的位置可设置于该环身30的两端32之处或临近该环身的两端,自该两开孔40’施予向外的作用力时,可改变该环身30的外径。
本较佳实施例的该两开孔40’设于环身30的内周缘,因此,各该连通口42’连通该环身30的内周缘。本说明书定义,连通口42’所在之处为开孔40’的外侧,连接该连通口42’与该封闭端44’的该外侧壁46形成一挡止边缘,可防止扣环钳脱出开孔40’。
本实施例的C形扣20'为外扣式的扣件,可扩大外径,该连通口42’的中心较该封闭端44’靠近C形扣的前侧。
请参阅图10,该两开孔40’可斜向地设于该环身30上,所述的斜向指界于环身30的切线方向T与法线方向N之间的方向。该两开孔40’大致上沿着向外的作用力的方向设于该环身30。各该开孔40’的连通口42’与封闭端44’之间的连线形成该开孔40’的纵向L,该纵向L界于该切线方向T与法线方向N之间。于本较佳实施例,各开孔40’的连通口42’往封闭端44’的设置方向由C形扣20’的前侧往C形扣的后侧设置。
同样的,该环身30于本较佳实施例具有一致的宽度W;两窄部36,设于该环身30的两侧,为宽度较窄的部位,该两窄部36分别临近该两开孔40’,且位于该两开孔的后侧。两凹入38,分别设于环身30两侧的周缘,以形成各该窄部36。
使用时,如图11所示,以一扣环钳的钳嘴的两尖端52分别伸入该C形扣20’的该两开孔40’并施力,可改变该C形扣的外径。该两尖端52施予向外张开的作用力时,可使该环身30的外径扩大,进而可将该C形扣20’移向一对象的外周,例如图12所示的一轴65的外周,释放该外张的作用力后,该C形扣20’弹性回复,并扣入该轴65的环槽66中。
如图10所示,该扣环钳50扩大该C形扣20’的外径的操作过程中,扣环钳的尖端52受开孔40’的挡止边缘(即该外侧壁46)挡止,无法脱出开孔40’,可确保操作过程中,扣环钳的尖端52不会脱离C形扣20’。
本实用新型所提供的C形扣20、20’设置开孔40、40’供扣环钳结合及操作,C形扣20、20’的外径并无明显外凸的部位,可提升C形扣的使用便利性,并适用于更多的使用场合。且本实用新型的开孔可防止扣环钳脱离C形扣,确保操作的有效性。
上揭实施例仅是说明本实用新型的特征而非限制,举凡由本实用新型的等效修改,均应视为本实用新型的保护范围。
