Description

多级调节开关
技术领域
本发明涉及一种开关，特别涉及一种多级调节开关。
背景技术
多级调节开关普遍应用于电子和电器设备，用于对设备的某一参数进行量的调节。现有的多级调节开关一般为旋钮，该旋钮可分为若干级，例如1、2、3、4级，分别对应旋钮的不同旋转位置，并分别对应设备的被调节参数的不同量级。该旋钮存在的一个问题是当调节时，旋钮很可能一次跳过过多的量级，例如，直接从1级跳到4级，使得被调节参数的量的变化过快，导致设备不能适应，从而损害设备。
发明内容
有鉴于此，本发明提供一种多级调节开关，其只能逐次进行单级调节。
所述多级调节开关，包括：壳体，壳体上开有孔，壳体内表面上环绕孔形成有彼此间隔设置的多个阻隔块，每一阻隔块的顶面在绕孔的一特定方向上自一端向另一端逐渐降低；按钮，位于壳体内，包括本体和环绕本体形成的多个支持块，本体从孔伸出到壳体外，多个支持块分别位于多个阻隔块之间的间隙中，每一支持块的顶面在绕孔的特定方向上自一端向另一端逐渐降低，支持块的最高端的高度等于或小于阻隔块的最低端的高度；多组导电片，对应多个支持块设置于壳体内；旋转件，包括弹性导电部和支撑柱，支撑柱可转动安装于壳体内，弹性导电部两端分别与其中一组导电片弹性接触并连通组导电片；及第一弹性件，驱使弹性导电部顶触于按钮的支持块的顶面，并继而驱使按钮抵触壳体。
由于支持块和阻隔块的顶面为斜面，按钮被按下时，旋转体的弹性导电部会滑动到另一组支持块上，从而连通另一组导电片。由于阻隔块高于支持块，每次按钮被按下都只能滑动到相邻的支持块，从而实现逐次单极调节。

图2是图1所示的多级调节开关的爆炸图。
图3是图1所示的多级调节开关的另一爆炸图，其相对图2倒置。
图4是图1所示的多级调节开关的立体剖视图。
图5-图7是图1所示的多级调节开关的工作原理图。
具体实施方式
请参考图1，其揭示了本发明一优选实施方式的多级调节开关10。请参考图2、图3、图4，该多级调节开关10包括一由上壳体20及下壳体30组成的壳体、分别安装于该壳体内的一按钮40、一旋转件50和一弹性件53，在本实施方式中，该弹性件53为弹簧。
上壳体20大致呈矩形，在上壳体20上形成有孔21，在上壳体20内表面上环绕孔21形成有彼此间隔设置的多个阻隔块22，每一阻隔块22的顶面在绕孔21的一特定方向上自一端向另一端逐渐降低。在该多个阻隔块22的外围还形成有若干连接柱23，每一连接柱23上形成有连接孔(未标示)。
下壳体30大致呈圆筒形，下壳体30的一端沿圆周方向形成有凸耳31，凸耳31上形成有连接孔(未标示)，螺钉(图未示)穿过凸耳31和连接柱23上的连接孔，将下壳体30安装于上壳体20上。下壳体30的底面的圆心位置向外凸出有容纳柱32，该容纳柱32内形成有通孔33，该通孔33呈台阶状，其在该容纳柱32远离下壳体30的底面的一端具有较小的直径。在下壳体30的圆周方向的内壁上粘贴有多组导电片60、61。导电片60、61分别与该多级调节开关10的多级调节电路连接，当一组导电片60、61被连通时，即开启该多级调节电路的一级电路。由于该多级调节电路是为人们所熟知的，在图中没有示出该多级调节电路。
旋转件50包括彼此垂直的一弹性导电部51和一支撑柱52，支撑柱52呈台阶轴状，支撑柱52较细的一端套有弹簧53并安装于下壳体30的容纳柱32的孔33内。在支撑柱52和弹性导电部51相连的一端，还安装有一抵触盘57。弹性导电部51包括一套筒54、一弹性件55、和两导电头56。在本实施方式中，该弹性件55为弹簧。导电头56分别可滑动的安装于套筒54的两端，弹簧55位于套筒54内并连接该两导电头56。
按钮40包括包括一台阶圆盘状的本体41及沿该本体41的圆周间隔设置的多个支持块42。本体41的直径较小的一端从上壳体20的孔21伸出到壳体外。支持块42位于阻隔块22之间的间隙中，每一支持块42的顶面在绕孔21的一特定方向上自一端向另一端逐渐降低，且支持块42的顶面的倾斜方向和阻隔块22的顶面的倾斜方向相同，支持块42的最高端的高度等于或小于阻隔块22的最低端的高度。
请参考图4、图5，当安装完成后，在支撑柱52上套的弹簧53的弹力作用下，套筒54抵触于按钮40的一对支持块42上，抵触盘57抵触于按钮40的本体41上，并继而驱使按钮40抵触上壳体20。由于阻隔块22的阻挡，旋转件50不能转动。在套筒54内的弹簧55的弹力作用下，导电头56分别抵触一组导电片60、61，从而连通多级调节开关10的其中一级电路。
请参考图6，当需要改变多级调节开关10的输入时，按下按钮40，支持块42向下运动，直至支持块42的顶面的最低端平齐或超出阻隔块22的顶面的最高端。请一并参考图7，由于弹簧53的弹力的作用，套筒54会沿支持块42和阻隔块22的斜面运动，直至相邻的另一支持块42阻挡住套筒54。当松开按钮40后，在弹簧53的弹性力作用下，按钮40复位，套筒54滑动到该相邻的支持块42上，此时导电头56抵触另一组导电片60、61，从而连通多级调节开关10的另一级电路。
由于支持块42和阻隔块22的配合，按钮40每一次按下都只能使得旋转件50的弹性导电部51滑动到相邻的支持块42上，从而只能连通相邻的一组导电片60、61，即只能逐次进行单极调节。
