具体实施方式
请参阅图1至图4,它们绘示了本发明的较佳实施例所提供的夹子滑座及升降机构。
一能滑动连接于升降杆100的夹子滑座,它包括一夹持单元200和一连接夹持单元200的插座单元300。
所述夹持单元200包括上压板210和下压板220。
所述下压板220与插座单元300通过螺钉700轴向相接,必要的时候,一摩擦垫520设于下压板220与插座单元300之间,能够增加摩擦力以限制插座单元300与下压板220间的转动,以及一垫片600与螺钉700配合于插座单元300的端面以紧固连接。
该上、下压板210、220都具有一抵靠部212、222、一作用板213、223及一设在抵靠部和作用板之间的枢接单元400;该枢接单元400包括一对设于上压板210两侧的的枢接片410,以及一转轴420穿过下压板和二枢接片410,该上、下压板210、220通过枢接单元400枢接在一起,并能绕着转轴420相对转动,使得所述夹持单元能够在锁接状态和松释状态之间变化。夹持单元处于锁接状态时,该上、下压板处于非平行状态,而且,所述上下压板的作用板对称。
所述上、下压板之间的自动复位是靠一弹性件2222实现的,在所述下压板220的抵靠部222上开设一容纳弹性件2222的凹槽2221,上压板210的底部设为凸起,该凸起与弹性件2222相适配,上压板210的凸起与弹性件2222相配合以顶抵于下压板220的抵靠部222,当停止按压上压板210时,它在弹性件2222弹力的作用下将向上运动,以实现自动复位。
该上、下压板210、220分别在作用板上设置有第一通孔211和第二通孔221,以分别套接升降杆100;如图1、3,所述第一通孔211内柱面的正面设有第一凹槽214,背面设有第一通槽215;所述第二通孔221内柱面的正面设有第二凹槽224,背面设有第二通槽225,第一凹槽214和第二凹槽224开口相对分衬摩擦垫510,第一通槽215和第二通槽225分衬摩擦垫511。
当夹持单元200处于锁接状态时(参见图3),该上、下压板处于非平行状态,并都与升降杆倾斜设置,所述倾斜角度对称,使得该摩擦垫510、511都紧接触在升降杆100,在夹子滑座和夹子滑座上插接物品的重力作用下和在复位弹力作用下,所述摩擦垫510和升降杆100之间产生作用力,在该作用力的作用下产生静摩擦力,通过该静摩擦力使得所述夹持单元200定位在升降杆100,能够限制通孔211、221与升降杆100之间的滑动。当夹持单元200处于松释状态时,该上、下压板处于平行状态,并都垂直与升降杆,使得所述通孔和升降杆之间松配合,最好具有一定间隙,以便自由上下滑动夹子滑座。
该升降机构,它包括一升降杆100、一能与升降杆100滑动连接的夹持单元200和一与夹持单元连接的插座单元300。它们的结构及连接关系与上述描述相同,在此不赘述。其操作原理也相同,即所述夹持单元200随着所述二压板210、220之间转动角度的改变而使夹持单元200处于锁接或松释状态,以固定或滑动于升降杆100上。
结合图3、图4所示,升降机构的升降方法为:
起始状态中,所述夹持单元处于锁接状态,所述上、下压板对称并都倾斜于升降杆,压板的摩擦垫510紧接触在升降杆100,并产生静摩擦力,利用该静摩擦力定位,如图3;
首先按压上压板210的按钮部216,解除夹持单元200对升降杆100的锁接,使上压板210绕着上、下压板的枢接点,即转轴420转动,上、下压板210、220之间的相互转动使二者之间的角度改变,从而改变通孔211、221与升降杆100之间的角度,使所述通孔211、221与升降杆100之间的位置关系出现变化,克服了静摩擦力,以使得所述夹持单元200处于松释状态,如图4所示,此时上、下压板210、220彼此平行,并都垂直于所述升降杆,而通孔211、221的内柱面不再抵靠于升降杆100的外柱面的正背部分,夹子滑座即可沿着升降杆100上下滑动;
需要固定夹子滑座时,停止按压上压板220,在弹性件2222的作用下,上压板210自动复位,此时上、下压板210、220之间具有一定角度,所述通孔211、221内柱面的正背部分紧靠于升降杆100的外柱面的正背部分,在摩擦力的作用下,夹持单元200处于锁接状态,如图3所示,夹子滑座停止滑动并固定于升降杆100上。
本实施例中,所述插座单元300可以用来插设手持花洒等物品。
以上所述,仅为本发明较佳实施例而已,故不能依此限定本发明实施的范围,即依本发明专利范围及说明书内容所作的等效变化与修饰,皆应仍属本发明涵盖的范围内。

  8. 升降机构,它包括一升降杆,其特征在于:它还包括一能与升降杆滑动连接的夹持单元和一与夹持单元连接的插座单元,所述夹持单元包括二相对转动枢接并能复位的上、下压板,该夹持单元随着所述二压板之间转动角度的改变而选择固定或滑动于升降杆上。
  9. 升降机构的升降方法,其特征在于:
    步骤1.按压上压板,使其绕着上、下压板的枢接点转动;
    步骤2.上、下压板之间的相互转动使二者之间的角度改变,从而改变使它们与升降杆之间的角度,使所述通孔与升降杆之间位置关系出现变化,以使得所述夹持单元处于松释状态;
    步骤3.当所述夹持单元处于松释状态时所述通孔内柱面的正背部分松配合于升降杆外柱面以能上下滑动夹子滑座;
    步骤4.停止按压上压板,此时所述通孔内柱面的正背部分紧靠于升降杆外柱面,夹持单元处于锁接状态,夹子滑座停止滑动并固定于升降杆上。
