Description

一种阻尼可调的阻尼器 技术领域
本发明涉及卫浴领域，特别是一种阻尼可调的阻尼器。
背景技术
坐便器包括陶瓷本体、座圈和上盖，由于座圈或上盖在未使用阻尼器的情况下，下降速度过快，容易和陶瓷本体发生碰撞而发出很大的响声，这一方面使用户心理不适，另一方面也容易损坏座圈或上盖，减少使用寿命。因此，阻尼器已越来越多的应用到坐便器上，它能够使座圈或上盖快速打开，不影响原先的打开动作，另一方面在下降的下半程，能够缓慢下降，大大减少碰撞力度。
现有液压阻尼器基本由轴套、轴芯和单向过油叶片等密封装配而成，通过轴芯转动使轴套中的阻尼油流动，叶片打开过油通道使得阻尼油向一个方向快速流动，阻尼油对轴芯无液压阻力，轴芯可快速转动；而当轴芯反向转动，叶片封闭过油通道使阻尼油流动缓慢，阻尼油产生液压阻力作用于轴芯，使轴芯缓慢转动；因此调节阻尼油在轴套中产生液压阻力的大小，即可调节轴芯阻尼转动时的转速。
但现有的一些阻尼器，通常不具有调节功能。一些具备调节功能的，通常是在轴芯上设刻槽(过油槽)，通过封闭或打开刻槽，来实现调节功能，但这种方式，使得轴芯的加工难度加大。此外，过油需要从轴芯的端面到侧面，过油油路长。
发明内容
为解决上述问题，本发明提出一种阻尼可调的阻尼器。
本发明提出的一种阻尼可调的阻尼器，包括一轴套、一与轴套密封转动配合的轴芯，轴套内腔壁上设有两个限定翼板转动幅度的隔油筋，轴芯的两翼板上分别设有一与轴套内腔壁滑动配合的单向过油叶片，其特征在于：所述轴套内腔两端分别为用于插入轴芯的轴芯插口和用于插入调节螺母的螺母插口,其中，螺母插口中螺纹连接一调节螺母，调节螺母端面设有支撑轴孔；轴芯末端设有一能够密封转动配合插入调节螺母支承轴孔的支承轴，调节螺母端面和轴芯末端之间设有可调间隙。
在一实施例中，调节螺母和螺母插口都包括上段、中段和下段，且下段的直径大于中段的直径，中段的直径大于上段的直径；
其中，调节螺母上段的上端面设有支承轴槽；中段设有一环槽，环槽中套设一使调节螺母和轴套底部螺母插口形成密封的调节螺母密封圈；调节螺母的下段外周面设外螺纹。
在优选的实施例中，调节螺母中段和上段，其长度分别和螺母插口的中段和上段的直径相近或相等，；螺母插口下段设内螺纹，调节螺母的下段的外螺纹和轴套的下段的内螺纹配合，但调节螺母的下段的长度小于或等于轴套的下段的长度，
在优选的实施例中，所述的可调节间隙，其最大调节距离为R。
在优选的实施例中，在锁紧位置，调节螺母的上端面和轴芯底平面锁紧。
在优选的实施例中，在最大调松位置，调节螺母的下端面和轴套的底面平齐，且此位置，密封圈仍然处于螺母插口的中段内，保持密 封。
在一实施例中，调节螺母在锁紧位置，其端面和轴套横向底板平齐。
在一实施例中，轴芯的支承轴端面直径小于调节螺母的端面直径。
在一实施例中，所述轴套的横向底板与翼板的轴向下端面贴触滑动配合，所述轴套横向底板上、两隔油筋旁边对称设有一对卸油槽。
在一实施例中，所述的内盘面上设有一对在轴芯非阻尼转动时打开隔油筋两侧油路的通流槽。
在一实施例中，在轴芯的顶部上设有一与轴套轴芯插口套接转动配合的盘体，所述的翼板的顶端与盘体内盘面连接，内盘面与隔油筋的顶部滑动配合,所述的翼板径向上设有一用于安装过油叶片的叶片槽。
在一实施例中，所述的轴套轴芯插口还设有一压盖，压盖与盘体之间还套有垫片和密封圈。
本发明的有益效果是：
1、通过调节螺母的锁紧或调松，能够调节调节螺母端面和轴芯末端之间的可调间隙大小，即可调节阻尼油在翼板两侧之间的过油速度，进而调节阻尼器的阻尼力大小，控制轴芯的转动速度。
2、本发明在轴芯上无需设刻槽，大大降低了轴芯的加工难度。
2、轴芯直接插到调节螺母，使过油油路更短，调节更灵活，扭矩更大,同时减少零件，组装方便。
3、在优选的实施例中，调节螺母和螺母插口都包括上段、中段和下段，且下段的直径大于中段的直径，中段的直径大于上段的直径；这样，在上段的位置，轴套的壳具有较大的厚度，结实耐用。
4、在优选的实施例中，所述的可调节间隙，其最大调节距离为R；在锁紧位置，调节螺母的上端面和轴套内腔的底面平齐；在最大调松位置，调节螺母的下端面和轴套的底面平齐，且此位置，密封圈仍然处于螺母插口的中段内，保持密封，这样，方便使用者根据需要直观地调节间隙(即锁紧-或是调制和底端平齐这个位置之间调节)，且不会漏油。

如图2所示，本发明的轴套3的轴套内腔具有一可插入轴芯5的轴芯插口3-1和一用于支撑轴芯5末端转动的螺母插口3-2,轴套内腔与螺母插口3-2之间形成横向底板3-3，两隔油筋3-4中心对称设置在轴套内腔的腔壁上，隔油筋3-4径向面与螺母插口3-2相平，隔油筋3-4从轴芯插口3-1至延伸到横向底板3-3固定，隔油筋3-4与轴芯插口3-1平齐，轴套横向底板3-3上、两隔油筋3-4旁边对称设有一对底面过油槽3-5；
如图3所示，本发明的轴芯5的中部设有一与轴套3轴芯插口3-1套接转动配合的盘体5-1，轴芯5上对称设有一对翼板5-2，每个翼板 5-2的顶端与盘体5-1的内面5-11连接，翼板5-2的下端面5-3可与横向底板3-3滑动配合，内盘面5-11可与隔油筋3-4的顶部滑动配合,内盘面5-11上设有一对在轴芯3非阻尼转动时打开隔油筋3-4两侧油路的通流槽5-4。
翼板5-2径向上设有一用于安装单向过油叶片4的叶片槽5-5，过油叶片4与叶片槽5-5摆动配合。如图5所示，在本实施例中，是采用横截面大体上为T形的叶片，其中T形的凸筋4-1上设有两道过油槽4-2，T形的一侧凹槽4-4，和翼板5-2的叶片槽之间能够密闭配合而封闭过油槽4-2，而另一侧凹槽4-5，和翼板5-2的叶片槽之间不能密闭配合而封闭过油槽4-2。单向过油叶片及其和叶片槽之间的配合，也可采用现有技术的其它结构，其部分非本发明的重点。
轴芯5末端设有一支承轴5-6，该支撑轴5-6的直径小于轴芯主轴的直径。
本发明螺母插口3-2中螺纹连接一调节螺母1，如图4所示,调节螺母1包括上段1-1,中段1-2和下段1-3。下段1-3的直径大于中段1-2的直径，中段1-2的直径大于上段1-1的直径。上段1-1的上端面1-4设有支承轴槽1-5，支承轴5-6能够密封地插入该支承轴槽1-5中。中段1-2设有一环槽1-6，环槽1-6中套设一使调节螺母1和轴套3底部螺母插口3-2形成密封的调节螺母密封圈2。调节螺母1的下段1-3外周面设外螺纹。
参见图10，轴套3的螺母插口3-2，其由下至上包括下段3-21，中段3-22和上段3-23。下段3-21设内螺纹，直径大于中段，中段的 直径大于上段。调节螺母1的下段的外螺纹和轴套的下段3-21的内螺纹配合，但调节螺母1的下段1-6的长度小于轴套的下段3-21的长度，两者之间的差值为R。
在本实施例中，调节螺母1中段1-2和上段1-1，其长度分别和螺母插口3-2的上段3-21和中段3-22的长度相等。在其它实施例中，也可以不相等。
在本实施例中，在锁紧位置，调节螺母的上端面1-4和轴套内腔的底面平齐。在其它实施例中，也可以不平齐
在最大调松位置，调节螺母的下端面1-7和轴套的底面3-7平齐，且此位置，密封圈2仍然处于螺母插口3-2的中段3-22内，保持密封。在其它实施例中，也可以不平齐。但优选为平齐方式。
本发明的组装如下，
如图6至图10所示，把单向过油叶片4套于轴芯5翼板5-2上的叶片槽5-5中，然后整体套入轴套3的轴套内腔中，单向过油叶片4边沿与轴套内腔的腔壁周向贴触滑动配合，翼板5-2的下端面与轴套3的横向底板3-3贴触滑动配合，两个翼板5-2位于两个隔油筋3-4之间，轴芯5上盘体5-1与轴芯插口3-1转动配合，并且隔油筋3-4顶部与轴芯5上盘体5-1的内盘面5-11贴触滑动配合，隔油筋3-4径向与轴芯3的径面贴触滑动配合，因此两个隔油筋3-4把轴套分隔成两个可储存阻尼油的油腔。
调节螺母1旋入螺母插口3-2，使轴芯5末端的支承轴5-6与支承 轴槽1-2套合并转动配合，使被隔油筋3-4分隔成的两个阻尼油的油腔无法连通；然后把垫片6套于盘体5-1外环面，再把轴芯密封圈7套于垫片6上密封住盘体5-1与轴套轴芯插口3-1,然后把密封盖8压入轴芯插口3-1并采用焊接固定，即完成本发明的装配。
下面详细说明本发明的工作原理。
如图9所示，通过拧动调节螺母1使其端面1-4和轴芯5的下端面5-3密闭接触，使得被隔油筋3-4分隔成的油腔，即阻尼油被限定在该油腔中，把马桶盖板(图中未画出)连接在轴芯5上，如图7所示，把盖板上翻过程中，轴芯5上的翼板5-2滑过轴套横向底板3-3上的底面过油槽3-5时，阻尼油快速从底面过油槽3-5通过,同时翼板5-2挠动阻尼油时、阻尼油流压使翼板5-2叶片槽5-5中的单向过油叶片4摆动，翼板5-2的叶片槽之间不能密闭配合而封闭过油槽4-2，阻尼油可快速从过油槽4-2通过，因此在盖板上翻转前半程时，阻尼油对翼板5-2无液压阻力，因此盖板上翻前半程非常轻便，盖板上翻后半程时，隔油筋3-4滑过轴芯5上盘体5-1的内盘面5-11上的通流槽5-4，使轴套3被隔油筋3-4分隔成的两个阻尼油的油腔通过通流槽5-4连通，阻尼油可在整个轴套3的轴套内腔中自由流动，使阻尼油对翼板5-2无液压阻尼力，因此上述盖板上翻的全过程中，阻尼油对轴芯5无液压阻尼力，因此盖板上翻全程十分轻快便捷。
如图8所示，把盖板下翻前半程中，隔油筋3-4反向滑过轴芯5上盘体5-1的内盘面5-11上的通流槽5-4，使轴套3被隔油筋3-4分 隔成的两个阻尼油的油腔通过通流槽5-4连通，阻尼油可在整个轴套3的轴套内腔中自由流动，使阻尼油对翼板5-2无液压阻尼力，因此上述盖板下翻的前半程中，阻尼油对轴芯5无液压阻尼力，轴芯5可快速转动，盖板可快速下翻转，阻尼油产生流动压使翼板5-2叶片槽5-5中的单向过油叶片4反向摆动，单向过油叶片4另一面与叶片槽5-5的槽壁相贴触关闭过油槽4-2,当隔油筋3-4与通流槽5-4错开与内盘面5-11贴触瞬间进入盖板翻转的后半程，隔油筋3-4快速把轴套内腔隔成两个限定住阻尼油的油腔，由于过油槽4-2关闭，阻尼油仅可从轴套横向底板3-3上的底面过油槽3-5中缓慢通过，因此阻尼油对翼板5-2产生液压阻尼力而使轴芯5缓慢转动，实现盖板的后半程下翻转的慢落功能，因此盖板下翻转过程是先快后慢。
由于盖板下翻转后半程由于阻尼油仅可从轴套横向底板3-3上的底面过油槽3-5中缓慢通过，阻尼油对翼板5-2产生液压阻尼力而使轴芯5以一定的缓慢转动，若是需要调节轴芯5阻尼工作状态的转动速度，需调节阻尼油的对翼板5-2的产生液压阻尼力的大小，如图6和图11所示，反向旋转调节螺母1使其使其端面1-4和轴芯5的下端面5-3分离，两者之间产生过油间隙9，使被隔油筋3-4分隔成的两个阻尼油的油腔通过该过油间隙9连通，通过旋动调节螺母1调整其端面1-4和轴芯5的下端面5-3的间隙大小即可调节控制油腔阻尼油从过油间隙9之间经过的流速，改变阻尼油对翼板5-2液压阻尼力的大小，调节轴芯5的转速，实现盖板阻尼慢落翻转速度可调之目的。在最大调松位置，调节螺母的下端面1-7和轴套的底面3-7平齐，且此 位置，密封圈2仍然处于螺母插口3-2的中段3-22内，保持密封。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。
工业实用性
现有的一些阻尼器，通常不具有调节功能。一些具备调节功能的，通常是在轴芯上设刻槽(过油槽)，通过封闭或打开刻槽，来实现调节功能，但这种方式，使得轴芯的加工难度加大。此外，过油需要从轴芯的端面到侧面，过油油路长等问题，本发明解决了现有阻尼器的这些问题具备工业实用性。
