Abstract

本实用新型所述的自动伞开关由设在伞柄上的按钮和按钮轴向复位弹簧及设在伞杆中的弹节组成,伞柄上设有限定按钮运动方向的径向导孔、轴向导槽和按钮防脱槽,这种开关在解除对伞骨的锁定时,其按钮首先要在外力作用下作轴向位移,然后再作径向位移,在先的轴向位移是在后的轴向位移的前提,实质上是对解锁动作的制约和锁定,因此,本实用新型具有锁定保险功能,这一特点有利于自动伞从制造到销售的各个环节。

Description

自动伞开关
本实用新型涉及一种自动伞开关。
自动伞开关大多是按钮式开关,由设置在伞柄上的按钮和套装在伞杆内孔中并同伞杆铰链连接的弹节组成,因为这种开关缺少锁定保险机构,一旦误触按钮,即刻解除锁定,伞骨就要在储能弹簧的作用下迅速张开,这一点在制造时会使组装不便,在运输时会使伞具损坏,在销售时又会伤及他人。
本实用新型的目的是提供一种具有锁定保险功能的自动伞开关。
公知的自动伞开关的按钮安装在伞柄的径向导孔中,本实用新型的解决方案是在伞柄径向导孔的外侧设置供按钮轴向往复位移的轴向导槽和按钮防脱槽,设置在按钮上的防脱凸块则嵌装在按钮防脱槽中,此外,在防脱凸块的内侧还设有按钮轴向复位弹簧。
上述结构的自动伞开关的按钮首先要在外力的作用下作轴向位移,然后再作径向位移才能使开关解除锁定,在先的轴向位移是在后的径向位移的前提,实质上是对解锁动作的制约和锁定。因此,本实用新型所述的自动伞开关具有锁定保险功能,这一特点有利于产品从制造到销售的各个环节。
下面结合附图和实施例来阐明本实用新型的具体内容。
附图是本实用新型的结构图。
本实用新型所述的自动伞开关由设置在伞柄1上的按钮2和套装在伞杆3的内孔4中并同伞杆3铰链连接的弹节5组成,伞柄1设有限定按钮2运动方向的导向结构,一是径向导孔6;二是设置在径向导孔6外侧供按钮2轴向位移的轴向导槽7;三是防止按钮2从孔槽中脱出的按钮防脱槽8。此外,按钮2上还设有按钮防脱凸块9和按钮轴向复位弹簧10,其中按钮防脱凸块9嵌装在按钮防脱槽8中,按钮轴向复位弹簧10设置在按钮防脱凸块9的内侧,为了缩小结构尺寸并利于弹簧工作,按钮2上设有弹簧导向孔11,伞柄1上设有弹簧导向柱12,按钮轴向复位弹簧10套装在弹簧导向孔11和弹簧导向柱12中,并支承在伞柄1和按钮2上,为了适应这种自动伞开关组装的要求,伞柄1必须采用分体组合结构,在本实施例中,伞柄1是三体组合结构。
