Description

说明书 一种恒力升降杆
技术领域
[1] 本发明是关于一种卫浴用品， 特别是指一种调节固定花洒的恒力升降杆。
背景技术
[2] 我们日常使用的淋浴喷头安装主要有两种方式： 一种是固定式， 此种形式主要 是用于宾馆或是标准公寓等处的嵌墙式的暗装接口上， 淋浴喷头的位置是固定 的； 另一种是活动式， 此种形式主要是目前家居中普遍釆用的固定方式， 该淋 浴喷头主要是从供水接口用软管连接出水， 其使用位置为活动的， 即俗称花洒 ， 使用吋可以用手拿着， 亦可以插固在墙体上的花洒固定座中以作为固定式使 用。
[3] 为进一步令淋浴喷头具有多个固定位置使用的灵活性， 现有的卫浴房内都安装 有花洒升降杆， 此升降杆上活动固定有一花洒固定座， 如此调整花洒固定使用 吋的高度， 方便大人与小孩的调整使用。
[4] 但是该升降杆上的花洒固定座的调节都是依靠花洒固定座的旋紧装置实现， 即 在调整吋需要先旋松该旋紧装置， 将花洒固定座沿升降杆滑至所需位置吋再旋 紧该旋紧装置以将花洒固定座固定在所需的高度位置， 因此该升降杆的调节实 施， 需要双手的操作， 若在淋浴过程中双手有沐浴泡沫， 却无法实现快速的调 整花洒固定座。
发明内容
[5] 本发明的目的是提供一种对花洒固定座操作便利、 调整省力的恒力升降杆。
[6] 为实现上述目的， 本发明的解决方案是： 一种恒力升降杆， 由杆体与套置于杆 体上的花洒固定座构成， 花洒固定座的外侧设有固定花洒手柄的套座； 其中： 花洒固定座包括滑座上盖、 滑座下盖、 浮动块、 楔形块、 复位弹簧及力值定位 弹簧； 浮动块套置于杆体上， 其上部形成倒锥形套座， 下部呈径向设有容置槽
； 楔形块上部形成楔形体是伸置于上述浮动块的锥形套座中， 楔形块下部形成 座体与复位弹簧呈轴向设置于上述浮动块的容置槽中； 楔形体内侧设有摩擦片 ； 浮动块活动置于滑座上盖与滑座下盖构成的容置腔中， 力值定位弹簧位于浮 动块与滑座上盖之间。
[7] 所述滑座上盖为一罩壳， 罩壳偏心的形成一配合杆体截面的通孔， 在壳体内侧 壁的下部形成一配合孔。
[8] 所述滑座下盖为一盖体， 其内侧形成一阶梯形卡块以伸置于滑座上盖的配合孔 中与滑座上盖形成活动配合， 在滑座下盖形成有配合杆体截面的通孔。
[9] 所述浮动块为一偏心套筒， 套筒上部形成倒锥形套座， 在套座外侧的浮动块上 轴向形成一沉槽以容置力值定位弹簧。
[10] 所述浮动块的下部形成一配合杆体截面的套孔。
[11] 所述楔形体的座体自下向上轴向形成一容置复位弹簧的套座。
[12] 所述摩擦片是嵌置于楔形体内侧。
[13] 釆用上述方案后， 由于本发明升降杆杆体上的花洒固定座完全依靠其内部的浮 动块及楔形块的设置并配合力值定位弹簧及复位弹簧的结构， 可以令花洒固定 座由楔形体与浮动块倒锥形套座的楔紧关系并配合摩擦片对杆体的摩擦力实现 自锁自动定位的功能， 以此实现快速调整花洒固定座在升降杆杆体上的高度选 择， 相对现有技术中双手调节花洒固定座的结构， 其在操作上更加便利快捷。 附图说明
[14] 图 1为本发明花洒固定座沿升降杆向上滑动及静止状态示意图；
[15] 图 2为本发明花洒固定座沿升降杆向下滑动的示意图。
具体实施方式
[16] 如图 1、 2所示， 本发明的一种恒力升降杆， 其包括一升降杆杆体 1及活动套置 在该杆体 1上的花洒固定座 2。
[17] 升降杆杆体 1为一细长的管体， 其上下部通过固定座固定在墙体上。
[18] 花洒固定座 2包括滑座上盖 21、 滑座下盖 22、 浮动块 23、 楔块 24、 复位弹簧 25 及力值定位弹簧 26;
[19] 滑座上盖 21为一罩壳， 其外侧延伸一倒锥形套座 211以套置花洒手柄； 罩壳偏 心的形成一配合杆体 1截面的通孔 212， 在罩壳内侧壁的下部形成一配合孔 213;
[20] 滑座下盖 22为一对应罩壳的盖体， 其内侧形成一阶梯形卡块 221以伸置于上述 的配合孔 213中与滑座上盖 21形成活动配合， 同吋与滑座上盖 21形成一容置腔 A ， 另在该滑座下盖 22上对应上述通孔 212的位置亦形成配合杆体 1截面的通孔 222
[21] 浮动块 23为一偏心套筒， 套筒上部形成倒锥形套座 231， 在套座 231外侧的浮动 块 23上轴向形成一沉槽 232以容置力值定位弹簧 26； 而在套座 231下部向外侧径 向形成容置槽 233以容置楔形块 24; 浮动块 23的下部形成一配合杆体 1截面的套 孔 234;
[22] 楔形块 24为一异形块体， 其内侧上部形成一配合上述倒锥形套座 231的楔形体 2 41， 该楔形体 241的内侧嵌置一摩擦片 242， 在楔形块 24的下部形成为座体 243而 容置于上述容置槽 233中， 该座体 243自下向上轴向形成一套座 244以容置复位弹 簧 25。
[23] 配合图示， 组合吋， 将装置有复位弹簧 25的楔形块 24的座体 243放置于浮动块 2 3的容置槽 233中， 与此同吋楔形体 241是伸置于浮动块 23的套座 231中； 再将力 值定位弹簧 26容置于浮动块 23的沉槽 232中， 将装配好的浮动块 23自滑座上盖 21 下部向上置于滑座上盖 21中， 最后将滑座下盖 22利用其卡块 221与滑座上盖 21的 配合孔 213配合即形成一花洒固定座 2， 此吋的浮动块 23是活动的位于滑座上盖 2 1与滑座下座 22构成的容置腔 A中， 最后将花洒固定座 2套置于升降杆杆体 1上， 与此同吋力值定位弹簧 26的上部是顶靠在滑座上盖 21的上壁上， 而下部是顶靠 在浮动块 23的沉槽 232下部； 而复位弹簧 25的上端是顶靠在楔形块 24座体 243的 套座 244中， 而下端是顶靠在浮动块 23的容置槽 233的下壁上， 另楔形体 241内侧 的摩擦片 242与杆体 1接触。
[24] 如图 1所示， 正常状态受力值定位弹簧 6的作用， 该浮动块 23的下端是与滑座下 盖 22接触， 此吋楔形块 24在复位弹簧 25的伸张力作用下已经靠紧浮动块 23的套 座 231的锥面， 摩擦片 242与杆体 1接触而产生摩擦力。 由于摩擦力的作用， 整个 花洒固定座 2是固定在升降杆杆体 1上不会下滑。
[25] 当花洒固定座 2需要升高高度吋， 即令花洒固定座 2相对升降杆杆体 1向上滑动 吋， 向上抬动整个花洒固定座 2， 由于摩擦片 242的摩擦力的作用使得楔形块 24 暂吋不动， 而浮动块 23则随花洒固定座 2—起向上运动， 楔形块 24的楔形体 241 受浮动块 23的套座 231锥面的压力松开， 摩擦片 242与杆体 1的摩擦力迅速下降， 则花洒固定座 2会容易顺利的上行滑动， 待滑至所需位置吋， 松释花洒固定座 2 ， 力值定位弹簧 26的作用， 该浮动块 23的下端是与滑座下盖 22接触， 此吋楔形 块 24在复位弹簧 25的伸张力作用下已经靠紧浮动块 23的套座 231的锥面， 摩擦片 242与杆体 1接触而产生摩擦力。 由于摩擦力的作用， 整个花洒固定座 2是固定在 升降杆杆体 1上不会下滑， 从而实现定位。
[26] 如图 2所示， 当花洒固定座 2需要降低高度吋， 即令花洒固定座 2相对升降杆杆 体 1向下滑动吋， 由于摩擦片 242的摩擦力的作用使得楔形块 24暂吋不动， 而滑 座上盖 21只能压缩力值定位弹簧 26继续向下运动， 当滑座上盖 21与楔形体 241上 端接触吋， 浮动块 23的倒锥形套座 231对楔形体 241的楔捆趋势下降， 此吋摩擦 片 242的正压力慢慢降低， 摩擦力也随之降低， 在一定的力值的情况下可以使花 洒固定座 2向下滑动， 滑至所需位置吋， 松释花洒固定座 2， 在力值定位弹簧 26 的复位力的作用， 该浮动块 23的下端是与滑座下盖 22接触， 此吋楔形块 24在复 位弹簧 25的伸张力作用下已经靠紧浮动块 23的套座 231的锥面， 摩擦片 242与杆 体 1接触而产生摩擦力。 由于摩擦力的作用， 整个花洒固定座 2是固定在升降杆 杆体 1上不会下滑， 从而实现定位。
工业实用性
[27] 本发明一种恒力升降杆， 其花洒固定座 2完全依靠其内部的浮动块 23及楔形块 2 4的设置并配合力值定位弹簧 26及复位弹簧 25的结构， 可以令花洒固定座 2在杆 体 1上实现自锁自动定位的功能， 以此实现快速调整花洒固定座 2在升降杆杆体 1 上的高度选择， 相对现有技术中双手调节花洒固定座 2的结构， 其在操作上更加 便利快捷， 具有良好的工业实用性。
