Description

一种纹绣仪的操作手柄 技术领域
本发明涉及一种纹绣仪，尤其涉及一种纹绣仪的操作手柄。
背景技术
纹绣是一种破皮上色的化妆方法，将色料刺进皮肤，并到达一定深度，以保留数月到数年。在操作过程中，纹绣仪通过紧固部件与纹绣针刺组件临时固定，以持续为所述针刺组件的针刺提供入刺的动力。现有纹绣仪和相应的纹绣针刺组件临时固定的方式较为简单，一般就是通过单一类型的结构，如弹性防滑件、旋转锁扣、螺纹结构等其中的一种进行紧固，提供单一方位的防脱阻力限制松脱。
由于纹绣仪为针刺组件的针刺部，所提供的动力持续时间长并且震动频率高，所述针刺组件非常容易在操作过程中，相对纹绣仪发生松脱，经常造成色料进入纹绣仪紧固部端口污染仪器，甚至造成针刺组件飞离纹绣仪，误伤使用者或操作者的意外事故，存在一定的安全隐患。同时，因为只采用一次紧固，可能安装使用的时候，出现中轴线不重合的情况出现，这样就会影响后续操作使用的稳定性，影响使用效果，还容易松脱。
发明内容
本发明目的是提供一种纹绣仪的操作手柄，通过使用该结构，能够增加操作手柄与纹绣头的连接牢固性，防止纹绣过程中纹绣头与操作手柄松脱，提高纹绣过程中的稳定性及安全性。
为达到上述目的，本发明采用的技术方案是：一种纹绣仪的操作手柄，包括壳体及设置于壳体内的驱动机构，所述壳体底部设有第一紧固件，所述壳体的外部安装有一套筒，所述套筒的下方设置于所述第一紧固件的外部，且所述套筒的底部内壁上设有第一内螺纹；
所述套筒的顶部与所述壳体的中部外表面螺接相连。

上述技术方案中，所述第一紧固件的底部外表面上设有至少一组弹性密封件。
上述技术方案中，所述第一紧固件的底部外表面上对称设有两组限位卡扣。
上述技术方案中，所述第一紧固件的底部设有底部螺纹。
上述技术方案中，所述第一螺纹的螺旋方向与所述第一内螺纹的螺旋方向相反；所述底部螺纹的螺距大于所述第一内螺纹的螺距，所述底部螺纹为粗螺纹，所述第一内螺纹为细螺纹。
上述技术方案中，所述套筒与所述第一紧固件之间还可拆卸的安装有一弹性夹头，所述弹性夹头的顶部外壁上设有连接外螺纹，所述弹性夹头经所述连接外螺纹与所述套筒的第一内螺纹螺接相连，且所述弹性夹头与所述第一紧固件之间设有间隙；所述套筒相对于所述弹性夹头朝下移动时，推动所述弹性夹头的底部闭合；所述套筒相对于所述弹性夹头朝上移动时，所述弹性夹头自复位，使所述弹性夹头的底部张开。
上述技术方案中，所述弹性夹头包括连接部及设置于连接部底部的多组弹性夹爪，相邻所述弹性夹爪之间设有变形间隙，所述连接外螺纹设置于所述连接部的顶部外表面上，每组所述弹性夹爪的上方外缘面为导向斜面，所述导向斜面由下至上倾斜向内设置，所述套筒的底部抵于所述导向斜面上；所述套筒相对于所述弹性夹头朝下移动时，所述套筒的底部挤压所述导向斜面，推动所述弹性夹爪的底部朝向所述弹性夹头的轴线设置，使所述弹性夹头闭合；所述套筒相对于所述弹性夹头朝上移动时，所述弹性夹爪的底部朝外自动恢复，所述弹性夹头打开。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
1.本发明中壳体外部设置套筒，通过套筒的设置，在第一紧固件的基础上，能够作为与纹绣头连接的第二紧固件，实现双重紧固，能够有效防止纹绣头与操作手柄连接使用过程中出现松脱的问题，提高纹绣过程中的稳定性及安全性；
2.本发明中通过限位环的设置，能够限制套筒在壳体上面的相对移动，防止套筒丢失，防止安装完成之后套筒相对于壳体移动，保证连接紧固的稳定性；
3.本发明中第一紧固件能够采用弹性密封件、限位卡扣、螺纹的方式与纹绣头进行连接，这样套筒适用于不同形式的第一紧固件，提高适用范围，保证操作手柄与纹绣头连接的牢固性及稳定性；
4.本发明中还可以在第一紧固件与套筒之间设有弹性夹头，通过套筒与弹性夹头之间的相对移动，从而推动弹性夹头张开及闭合，从而实现二次紧固，紧固速度快，效率高，紧固质量也好；同时，弹性夹头的设置，能够匹配老款只有一次紧固结构的纹绣头，这样能够提高适用范围，降低成本。

具体实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例一：参见图1～3所示，一种纹绣仪的操作手柄，包括壳体1及设置于壳体内的驱动机构2，所述壳体底部设有第一紧固件3，所述壳体的外部安装有一套筒4，所述套筒的下方设置于所述第一紧固件的外部，且所述套筒的底部内壁上设有第一内螺纹5；
所述套筒的顶部与所述壳体的中部外表面螺接相连。
在本实施例中，纹绣仪会包括操作手柄以及纹绣头6，本实施例中以纹绣头安装于操作手柄底部为例。驱动机构用于驱动纹绣头内部针刺组件的运动，从而实现纹绣工作。第一紧固件用于和纹绣头进行连接，现有技术中操作手柄也是经过第一紧固件和纹绣头之间进行连接。但是，只采用第一紧固件进行连接，及其容易松脱，存在较大的安全隐患，因此，通过在壳体外部设置套筒，套筒底部设置第一内螺纹，在第一紧固件与纹绣头进行一次紧固的结构相比，再利用套筒与纹绣头进行二次连接紧固，会在纹绣头上面设置外螺纹与套筒的第一内螺纹进行螺接，这样操作手柄与纹绣头的连接经过双重紧固，其连接强度更高，同时，即使一组紧固松脱，还有另外一组紧固将操作手柄与纹绣头进行连接，这样能够有效的保证纹绣过程中的稳定性及安全性。同时，在以往结构中，只采用一次紧固，即使一次紧固的时候，纹绣头与操作手柄的中轴线不重合，出现的外斜或者偏移，操作人员都难以发现，这样就会导致纹绣过程中精确性不好，还容易扎伤使用人员，存在一定的安全隐患。因此，本实施例中，设置套筒作为二次紧固，如果说一次紧固外斜或者偏移，二次紧固难以实现，则能够给予操作者进行提醒，便于纠正，保证操作手柄与纹绣头两者中轴线重合，保证纹绣过程中的精确性及安全性。
参见图1、3所示，所述壳体的中部外壁上设有第一外螺纹7，所述套筒的顶部内壁上设有第二内螺纹8，所述第二内螺纹与所述第一外螺纹螺接相连。
套筒经过第二内螺纹与壳体的第一外螺纹进行连接，这样能够保证套筒与壳体同轴，同时使得套筒与壳体连接稳定，不会出现相对滑动或者相对晃动的情况出现。
参见图1、3所示，所述壳体的中部外壁上设有一限位环9，所述限位环与所述第一外螺纹之间设有环形间距10，所述套筒的顶部设置于所述环形间距内。
所述限位环的内壁上设有环形槽11，所述环形槽正对所述第一外螺纹设置，所述套筒的顶部外缘面上设有环形凸起12，所述环形凸起移动设置于所述环形槽内。
本实施例中，套筒顶部外缘面的环形凸起会处在限位环的环形槽内，这样套筒在壳体上面螺旋，使得套筒相对于壳体上下移动的时候，会受到环形凸起及环形槽的限位，防止套筒与第一外螺纹脱离，也就是通过限位环对套筒进行限位，防止其从操作手柄上面掉落。
同时，在本实施例中，限位环以及操作手柄上可以开设螺孔，利用螺栓将限位环锁紧在操作手柄上面，限位环也可以粘接在操作手柄上面，或者其他方式，限位环与操作手柄的连接方式多种，根据实际情况选择即可。
也就是套筒以及限位环的安装，可以在现有的操作手柄上面进行改进，例如现有的操作手柄只具备第一紧固件，改造的时候，直接在操作手柄的外壁上面制作第一外螺纹，然后将限位环及套筒安装在操作手柄的外部即可，这样以往的操作手柄也可以直接升级，并且无需将以往操作手柄弃用，能够降低开发成本。
所述壳体的顶部安装有调节件13，所述调节件与所述壳体顶部螺接相连，所述调节件转动时，推动所述驱动机构朝下移动或朝上移动。
在本实施例中，驱动机构为马达及驱动轴，马达会推动驱动轴上下移动，驱动轴朝下的时候，会推动纹绣头内部针刺组件朝下移动，驱动轴朝上的时候，针刺组件自复位朝上移动，使得针刺组件的顶部会一直与驱动轴的底部接触，因此，驱动机构会驱动针刺组件往复的上下移动，从而实现纹绣工作。调节件上面设有供电机构，用于给予驱动机构供电，调节件与操作手柄螺接，这样在将调节件与操作手柄相对螺接转动的时候，调节件会拉动驱动机构上升或者下降，这样就能够调节针刺组件的伸出长度，也就是调节出针的长短。
参见图1、2所示，所述第一紧固件的底部外表面上设有至少一组弹性密封件14。会在第一紧固件的外表面设置对应数量的环形安装槽15，每组弹性密封件安装于一组环形安装槽内，利用环形安装槽对弹性密封件进行定 位。
在本实施例中，第一紧固件与纹绣头安装的时候，弹性密封件被挤压，发生弹性形变，会对纹绣头产生挤压力，并且增加与纹绣头的摩擦力，形成与针刺组件运动方向相反的轴向阻力，从而给予纹绣头沿轴向运动的限制，防止其与操作手柄分离。在本发明中，优选超过2组间隔设置的弹性密封件，这样与纹绣头安装定位的时候，如果只设置一组弹性密封件，这样第一紧固件与纹绣头之间容易晃动，采用2组及以上，相互限位，保证连接以及使用的稳定性。
实施例二：参见图4所示，一种纹绣仪的操作手柄，其结构与实施例一基本相似，不同点在于：所述第一紧固件的底部外表面上对称设有两组限位卡扣16。
在本实施例中，会在纹绣头上面采用两组卡槽与限位卡扣连接，构成旋转锁扣结构。
实施例三：参见图5～7所示，一种纹绣仪的操作手柄，其结构与实施例一基本相似，不同点在于：所述第一紧固件的底部设有底部螺纹17。
在本实施例中，第一紧固件与纹绣头的连接会采用螺接，不采用与实施例一那种插接方式。
所述第一螺纹的螺旋方向与所述第一内螺纹的螺旋方向相反；所述底部螺纹的螺距大于所述第一内螺纹的螺距，所述底部螺纹为粗螺纹18，所述第一内螺纹为细螺纹19。
在本实施例中，第一紧固件与纹绣头会采用螺纹连接的结构，与实施例一的紧配合方式不一样，但属于一种紧固方式。
粗牙螺纹的升角较大，由于粗牙螺纹升角大、螺距大，同样导程距离下螺牙数量越少，因此，对于粗牙螺纹来说，对安装的精准度要求较低，便于安装及拆卸。但是抗振性能相对弱一些，自锁性以及密封性相对差一点，较为容易发生松脱。细牙螺纹由于螺纹升角小螺距小，同样导程距离螺牙数量多，从而密封性好，抗振动性较弱自锁性较好，不容易发生松脱，但是对安装的精准度要求较高。
在本实施例中，在操作手柄与纹绣头进行连接的时候，第一紧固件插入到纹绣头内(纹绣头内会设置于对应第一紧固件配合的粗螺纹，与套筒配合 的细螺纹)，经过粗牙螺纹进行快速的对位，然后进行快速的锁紧定位，实现一次紧固，这样不仅实现了一次紧固，而且，套筒及纹绣头采用的是细牙螺纹，一次紧固给予了二次细牙螺纹一个导向及对位，使得套筒与纹绣头进行螺接的时候，能够直接快速的进行连接(常规的细牙螺纹连接方式中，可能多次螺接都难以对准，甚至导致螺纹滑丝现象的发生)。因此粗牙螺纹，细牙螺纹的分别采用，既能够保证连接强度及稳定性，同时，还能够提高安装的顺畅性及便利性。
参见图7所示，在本实施例中，在经过长时间、高频率振动作用，粗牙螺纹会先松动，也就是纹绣头相对于操作手柄朝下移动，也就是纹绣头的粗牙螺纹相对于第一紧固件的粗牙螺纹朝下移动，发生松退运动，但是，由于粗牙螺纹比细牙螺纹的螺纹升角更大，在相同外力的干扰下，粗牙螺纹比细牙螺纹的松退幅度更大，在前述的松退运动的推动下，套筒与纹绣头的细牙螺纹间距，会随着松退方向逐渐的消失，并接发生挤压，产生的压力逐渐增大，进而使得套筒与纹绣头之间细牙螺纹之间的接触面积和摩擦阻力增大，这样就会增加套筒与纹绣头的紧固力度，也就是提高操作手柄与纹绣头之间的紧固性能。因此，在本实施例中，不仅底部螺纹的螺旋方向与所述第一内螺纹的螺旋方形相反，会给予反向作用力，增加一个紧固效果，同时由于粗牙螺纹与细牙螺纹的使用，进一步增加紧固效果，两者相互制约，有效防止纹绣头出现松脱现象的发生，提高纹绣过程中的稳定性、牢固性及安全性，防止纹绣头脱落而发生安全隐患。
在本实施例中，所述第一紧固件的底部设有一空腔20，所述驱动机构的底部插设于所述空腔内，所述底部螺纹为内螺纹，内螺纹设置于空腔的内壁上。
实施例四：参见图8所示，一种纹绣仪的操作手柄，其结构与实施例三基本相似，不同点在于：所述底部螺纹17为外螺纹，所述外螺纹设置于第一紧固件的外壁上。
实施例五，参见图9、10所示，一种纹绣仪的操作手柄，其结构与实施例一、实施例二、实施例三、实施例四基本相似，不同点在于：所述套筒与所述第一紧固件之间还可拆卸的安装有一弹性夹头21，所述弹性夹头的顶部外壁上设有连接外螺纹22，所述弹性夹头经所述连接外螺纹与所述套筒的第 一内螺纹螺接相连，且所述弹性夹头与所述第一紧固件之间设有间隙；所述套筒相对于所述弹性夹头朝下移动时，推动所述弹性夹头的底部闭合；所述套筒相对于所述弹性夹头朝上移动时，所述弹性夹头自复位，使所述弹性夹头的底部张开。
所述弹性夹头包括连接部23及设置于连接部底部的多组弹性夹爪24，相邻所述弹性夹爪之间设有变形间隙25，所述连接外螺纹设置于所述连接部的顶部外表面上，每组所述弹性夹爪的上方外缘面为导向斜面26，所述导向斜面由下至上倾斜向内设置，所述套筒的底部抵于所述导向斜面上；所述套筒相对于所述弹性夹头朝下移动时，所述套筒的底部挤压所述导向斜面，推动所述弹性夹爪的底部朝向所述弹性夹头的轴线设置，使所述弹性夹头闭合；所述套筒相对于所述弹性夹头朝上移动时，所述弹性夹爪的底部朝外自动恢复，所述弹性夹头打开。
在实施例一、二、三、四中，二次紧固是直接通过套筒底部的第一内螺纹与纹绣头进行螺接，二次紧固采用的是螺接方式，在本实施例中，二次紧固不采用螺接方式，采用弹性夹头的夹紧方式，但是需要在套筒与第一紧固件之间设置弹性夹头。
即使纹绣头的外表面上设置有与之前套筒的第一内螺纹螺接的外螺纹，也可以正常的夹紧。
实际锁紧的时候，操作手柄的第一紧固件先与纹绣头连接之后，然后套筒与操作手柄螺接朝下移动的时候，会同步带动弹性夹头朝下移动，当弹性夹头处在需要夹紧位置的时候，操作人员压住弹性夹头(如果弹性夹头抵在纹绣头上面无法下移的时候，则无需操作人员压住弹性夹头)，使得弹性夹头不跟随套筒同步转动或者同步下移，套筒继续朝下移动，此时套筒会经过连接外螺纹与第一内螺纹转动螺接，套筒不仅相对于弹性夹头转动，还会相对朝下移动，由于导向斜面的存在，会推动弹性夹爪的底部朝内变形，也就是弹性夹头闭合卡住纹绣头，实现二次紧固。松开的时候，套筒相对于弹性夹头朝上移动，弹性夹爪自动恢复，使得弹性夹头张开，即可解除二次紧固。
在本实施例中，利用套筒带动弹性夹头张开及闭合实现二次紧固，与其他实施例的螺接方式有区别，但是同样使用二次紧固功能，即使纹绣头的外表面不设置外螺纹，为光面也能够锁紧限位，能够提高二次紧固的适用范围。
而且，弹性夹头与套筒可拆卸的连接，如果操作手柄需要匹配老款的纹绣头(老款纹绣头只有一次紧固机构，没有设置外螺纹与套筒的第一内螺纹匹配)，直接通过弹性夹头包覆夹紧纹绣头的外部，即可对老款的纹绣头进行二次紧固，这样能够提高适用范围，适配性腔，降低更换纹绣头的成本。
