Description

类哑铃状对称双向锥形螺纹内螺纹与传统螺纹的连接结 构 技术领域

背景技术
[0002] 螺纹的发明， 对人类社会进步产生深刻影响。 螺纹是最基础工业技术之一， 她 不是具体产品， 是产业关键共性技术， 其技术性能必须要有具体产品作为应用 载体来体现， 各行各业应用广泛。 5见有螺纹技术， 标准化水平高， 技术理论成 熟， 实践应用久远， 用之紧固， 则是紧固螺纹； 用之密封， 则为密封螺纹； 用 之传动， 则成传动螺纹。 根据国家标准的螺纹术语： “螺纹”是指在圆柱或圆锥表 面上， 具有相同牙型、 沿螺旋线连续凸起的牙体； “牙体”是指相邻牙侧间的材料 实体。 这也是全球共识的螺纹定义。
[0003] 现代螺纹始于 1841年英国惠氏螺纹。 按照现代螺纹技术理论， 螺纹自锁基本条 件是： 当量摩擦角不得小于螺旋升角。 这是现代螺纹基于其技术原理—“斜面 原理”对螺纹技术的一种认识， 成为现代螺纹技术的重要理论依据。 最早对斜面 原理进行理论解释的是斯蒂文， 他研究发现斜面上物体平衡的条件与力合成的 平行四边形定律， 1586年他提出了著名的斜面定律： 放在斜面上的一个物体所 受的沿斜面方向的重力与倾角的正弦成正比。 所述的斜面， 是指与水平面成倾 斜的光滑平面， 螺旋是“斜面”的变形， 螺纹就像包裹在圆柱体外的斜面， 斜面越 平缓， 机械利益越大 （见图 A） （杨静珊、 王绣雅， 《螺丝钉的原理探讨》 ， 《 高斯算术研究》 ） 。
[0004] 现代螺纹的“斜面原理”， 是基于斜面定律建立起来的斜面滑块模型 （见图 B）
， 人们认为， 在静载荷和温度变化不大条件下， 当螺纹升角小于等于当量摩擦 角， 螺纹副具备自锁条件。 螺纹升角 （见图 C） 又称为螺纹导程角， 就是在中径 圆柱上螺旋线的切线与垂直于螺纹轴线的平面间的夹角， 该角度影响螺纹自锁 和防松。 当量摩擦角就是把不同的摩擦形式最终转化成最普通的斜面滑块形式 时对应的摩擦角。 通俗讲， 在斜面滑块模型中， 当斜面倾斜到一定角度， 滑块 此时的摩擦力恰好等于重力沿着斜面的分量， 此时物体刚好处于受力平衡状态 ， 此时的斜面倾斜角称为当量摩擦角。
[0005] 美国工程师于上世纪中叶发明了楔形螺纹， 其技术原理仍旧遵循“斜面原理”。
楔形螺纹的发明， 受到“木楔子”启发。 具体说， 楔形螺纹的结构是在三角形螺纹 （俗称普通螺纹） 内螺纹 （即螺母螺纹） 的牙底处有一个与螺纹轴线成 25°〜 30° 夹角的楔形斜面， 工程实际都取 30°楔形斜面。 一直以来， 人们都是从螺纹牙型 角这个技术层面和技术方向去研究和解决螺纹防松脱等问题， 楔形螺纹技术也 不例外， 是斜楔技术的具体运用。
[0006] 但是， 5见有螺纹存在连接强度低、 自定位能力弱、 自锁性差、 承力值小、 稳定 性差、 兼容性差、 重复使用性差、 高温低温等问题， 典型的是应用现代螺纹技 术的螺栓或螺母普遍存在着容易松动缺陷， 随着设备频繁振动或震动， 引起螺 栓与螺母松动甚至脱落， 严重的容易发生安全事故。

[0007] 任何技术理论， 都有理论假设背景， 螺纹也不例外。 随着科技进步， 对连接破 坏已非单纯线性载荷更非静态更非室温环境， 存在线性载荷非线性载荷甚至是 二者叠加并由此产生更复杂破坏载荷情况， 应用工况复杂， 基于这样认识， 本 发明的目的是针对上述问题， 提供一种设计合理、 结构简单， 具有良好连接性 育 g、 锁紧性能的双向锥形内螺纹与传统螺纹的连接结构。
[0008] 为达到上述目的， 本发明采用了下列技术方案： 本类哑铃状对称双向锥形螺纹 内螺纹与传统螺纹的连接结构， 是由对称双向锥形螺纹内螺纹与传统螺纹外螺 纹组成螺纹连接副使用， 是一种特殊的合成了圆锥副与螺旋运动技术特点的螺 纹副技术， 所述的双向锥形螺纹内螺纹， 是一种合成了双向锥形体与螺旋结构 技术特点的螺纹技术， 所述的双向锥形体是由两个单锥形体组成， 是由左侧与 右侧锥度的方向相向且锥度相同和 /或近似相同的两个单锥形体双向组成， 上述 的对称双向锥形螺纹内螺纹是由双向锥形体呈螺旋状分布于筒状母体的内表面 形成内螺纹， 其完整单元体螺纹是一种中间小两端大且左侧锥度与右侧锥度相 同和 /或近似相同的呈类哑铃状的特殊双向锥形几何体。
[0009] 本类哑铃状对称双向锥形螺纹内螺纹与传统螺纹的连接结构， 所述的类哑铃状 对称双向锥形内螺纹定义， 可以表达为： “在圆柱或圆锥内表面上， 具有规定左 侧锥度和右侧锥度且左侧锥度与右侧锥度的方向相向且锥度相同和 /或近似相同 的对称双向锥形孔、 沿着螺旋线连续和 /或不连续分布的呈螺旋状且呈中间小两 端大的呈类哑铃状特殊双向锥形几何体。 ”因制造等方面原因， 对称双向锥形螺 纹的螺头、 螺尾可能是不完整的双向锥形几何体。 与现代螺纹技术不同， 螺纹 技术已由原先现代螺纹内螺纹外螺纹啮合关系转变为本双向锥形螺纹内螺纹外 螺纹抱合关系。
[0010] 本双向锥形内螺纹与传统螺纹， 包括相互螺纹配合的外螺纹与内螺纹， 内螺纹 是呈螺旋状分布于筒状母体内表面的双向锥形孔， 外螺纹是呈螺旋状分布于柱 状母体外表面的特殊锥形体， 即内螺纹以呈螺旋状双向锥形孔并以“非实体空间” 形态存在、 外螺纹以呈螺旋状特殊锥形体并以“材料实体”形态存在， 所述的非实 体空间是指能够容纳上述材料实体的空间环境， 内螺纹是包容件， 外螺纹是被 包容件： 内螺纹与外螺纹是一节一节旋合套接在一起抱合直至一侧双向承载或 左侧右侧同时双向承载或直至定径过盈配合， 两侧是否同时双向承载与应用领 域实际工况有关， 即双向锥形螺纹内螺纹的双向锥形孔一节一节包容传统外螺 纹缘于与双向锥形螺纹内螺纹的接触而形成的特殊锥形体， 即内螺纹是一节一 节抱合对应外螺纹。
[0011] 所述的螺纹连接副是由呈螺旋状的外锥面与呈螺旋状的内锥面相互配合构成圆 锥副形成螺纹副， 所述的双向锥形螺纹内圆锥体的内锥面为双向圆锥面， 当所 述的双向锥形内螺纹与传统外螺纹组成螺纹连接副， 是以双向锥形内螺纹内圆 锥面与传统外螺纹特殊圆锥面的结合面为支承面， 即以圆锥面为支承面， 实现 连接技术性能， 螺纹副的自锁性、 自定位性、 重复使用性和抗疲劳性等能力主 要取决于构成本双向锥形内螺纹与传统螺纹的双向锥形螺纹内螺纹锥形孔圆锥 面及其锥度大小以及传统螺纹外螺纹缘于与双向锥形内螺纹接触而形成的特殊 外锥面及锥度， 是一种非牙型螺纹。
[0012] 与现有螺纹斜面原理所表现的分布于斜面上的单向力以及内、 外螺纹是内牙体 与外牙体的啮合关系不同， 本双向锥形内螺纹与传统螺纹， 内螺纹体即双向锥 形体无论分布于左侧或右侧任何一侧单锥形体通过圆锥轴线截面是由圆锥体两 条素线双向组成即呈双向状态， 所述的素线是圆锥表面与通过圆锥轴线的平面 的交线， 本双向锥形内螺纹与传统螺纹的连接结构的圆锥原理所表现的是轴心 力与反轴心力， 二者均是由双向力合成， 轴心力与对应的反轴心力对顶， 内螺 纹与外螺纹是抱合关系， 即组成螺纹副是通过内螺纹抱住外螺纹即一节节锥孔 （内圆锥体） 抱合对应的一节节锥体 （外圆锥体） 直至抱合定径配合实现自定 位或直至定径过盈接触实现自锁， 即通过锥形孔与特殊锥形体径向抱合在一起 实现内圆锥体与外圆锥体自锁紧或自定位进而实现螺纹副的自锁紧或自定位， 而非传统螺纹内螺纹与外螺纹组成螺纹连接副是通过彼此牙体与牙体相互抵靠 实现螺纹连接性能。
[0013] 内螺纹与外螺纹的抱合过程达到一定条件会有一种自锁力， 所述的自锁力是由 内圆锥轴心力与外圆锥反轴心力之间所产生压强生成， 即当内圆锥与外圆锥组 成圆锥副， 内圆锥体的内圆锥面抱合外圆锥体的外圆锥面， 内圆锥面与外圆锥 面紧密接触。 所述的内圆锥轴心力与外圆锥反轴心力是本发明双向锥形螺纹技 术即圆锥副技术所独有的力的概念。
[0014] 内圆锥体以类似轴套的形态存在， 在外来载荷作用下， 内圆锥体生成指向或者 说压向圆锥轴线的轴心力， 所述的轴心力是由一对以圆锥轴线为中心呈镜像分 布且分别垂直于圆锥体两条素线的向心力双向合成， 即轴心力通过圆锥轴线截 面是由以圆锥轴线为中心呈镜像双向分布于圆锥轴线两侧且分别垂直于圆锥体 两条素线且指向或者说压向圆锥轴线共同点的两条向心力组成且当上述的圆锥 体与螺旋结构合成为螺纹并应用于螺纹副则上述的轴心力通过螺纹轴线截面是 由以螺纹轴线为中心呈镜像和 /或近似镜像双向分布于螺纹轴线两侧且分别垂直 于圆锥体两条素线且指向或者说压向螺纹轴线共同点和 /或近似共同点的两条向 心力组成， 所述的轴心力是以轴向并周向的方式密密麻麻地分布于圆锥轴线和 / 或螺纹轴线， 所述的轴心力对应的有一个轴心力角， 组成所述的轴心力的两条 向心力的夹角构成上述的轴心力角， 所述的轴心力角大小取决于圆锥体的锥度 大小即锥角大小。
[0015] 外圆锥体以类似轴的形态存在， 具备较强吸收外来各种载荷能力， 外圆锥体生 成与内圆锥体每一轴心力对顶的反轴心力， 所述的反轴心力是由一对以圆锥轴 线为中心呈镜像分布且分别垂直于圆锥体两条素线的反向心力双向合成， 即反 轴心力通过圆锥轴线截面是由以圆锥轴线为中心呈镜像双向分布于圆锥轴线两 侧且分别垂直于圆锥体两条素线且由圆锥轴线共同点指向或者说压向内圆锥面 的两条反向心力组成且当上述的圆锥体与螺旋结构合成为螺纹并应用于螺纹副 则上述的反轴心力通过螺纹轴线截面是由以螺纹轴线为中心呈镜像和 /或近似镜 像双向分布于螺纹轴线两侧且分别垂直于圆锥体两条素线且由螺纹轴线共同点 和 /或近似共同点指向或者说压向内螺纹圆锥面的两条反向心力组成， 所述的反 轴心力是以轴向并周向的方式密密麻麻地分布于圆锥轴线和 /或螺纹轴线， 所述 的反轴心力对应的有一个反轴心力角， 组成所述的反轴心力的两条反向心力的 夹角构成上述的反轴心力角， 所述的反轴心力角大小取决于圆锥体的锥度大小 即锥角大小。
[0016] 轴心力与反轴心力在圆锥副的内外圆锥有效接触时开始生成， 即圆锥副的内圆 锥体与外圆锥体的有效接触过程始终存在一对对应且相对顶的轴心力与反轴心 力， 所述的轴心力与反轴心力均是以圆锥轴线和 /或螺纹轴线为中心且呈镜像双 向分布的双向力而非单向力， 所述的圆锥轴线与螺纹轴线是重合轴线即是同一 轴线和 /或近似同一轴线， 反轴心力与轴心力是反向共线且当上述的圆锥体与螺 旋结构合成为螺纹并组成螺纹副是反向共线和 /或近似反向共线， 通过内圆锥与 外圆锥的抱合直至过盈则轴心力与反轴心力由此在内圆锥面与外圆锥面的接触 面生成压强并密密麻麻地轴向并周向均匀分布在内外圆锥表面的接触面， 当内 圆锥与外圆锥的抱合运动一直进行直至圆锥副达到过盈配合所生成压强将内圆 锥与外圆锥结合在一起， 即上述的压强已能做到内圆锥体抱合外圆锥体形成类 似整体构造体并在其促成的外力消失后并不会因为上述的类似整体构造体体位 的方向任意变化而在重力作用下导致内外圆锥体相互脱离， 圆锥副产生自锁紧 即螺纹副产生自锁紧， 这种自锁紧性对于除了重力之外的可能导致内外圆锥体 彼此相互脱离的其他外来载荷也有一定限度的抵抗作用， 圆锥副还具有内圆锥 与外圆锥相互配合的自定位性， 但并非任意轴心力角和 /或反轴心力角都能让圆 锥副产生自锁紧和自定位。
[0017] 当轴心力角和 /或反轴心力角小于 180°且大于 127°， 圆锥副具备自锁性， 轴心力 角和 /或反轴心力角无限接近于 180°时， 圆锥副的自锁性最佳， 其轴向承载能力 最弱， 轴心力角和 /或反轴心力角等于和 /或小于 127°且大于 0°， 则圆锥副处于自 锁性弱和 /或不具自锁性区间， 轴心力角和 /或反轴心力角趋向于向无限接近于 0° 方向变化， 则圆锥副的自锁性呈衰减趋势方向变化直至完全不具自锁紧能力， 轴向承载能力呈增强趋势方向变化直至轴向承载能力最强。
[0018] 当轴心力角和 /或反轴心力角小于 180°且大于 127°， 圆锥副处于强自定位状态， 容易达到内外圆锥体强自定位， 轴心力角和 /或反轴心力角无限接近于 180°时， 圆锥副的内外圆锥体自定位能力最强， 轴心力角和 /或反轴心力角等于和或小于 1 27°且大于 0°， 圆锥副处于弱自定位状态， 轴心力角和 /或反轴心力角趋向于向无 限接近于 0°方向变化， 则圆锥副的内外圆锥体相互自定位能力呈衰减趋势方向变 化直至接近完全不具自定位能力。
[0019] 本双向锥形螺纹连接副， 较之申请人此前发明的单锥形体的单向锥形螺纹只能 圆锥面单侧承载的不可逆性单侧双向包容的包容与被包容关系， 双锥形体的双 向锥形螺纹的可逆性左右两侧双向包容， 可以做到圆锥面左侧承载和 /或圆锥面 右侧承载和 /或左侧圆锥面右侧圆锥面分别承载和 /或左侧圆锥面右侧圆锥面双向 同时承载， 更限制锥形孔与特殊外锥体之间的无序自由度， 螺旋运动又让双向 锥形内螺纹与传统螺纹连接结构获取了必须的有序自由度， 有效合成了圆锥副 与螺纹副技术特点形成全新螺纹技术。
[0020] 本双向锥形内螺纹与传统螺纹的连接结构在使用时传统外螺纹的特殊圆锥面与 双向锥形螺纹内螺纹的双向锥形孔圆锥面相互配合。
[0021] 本双向锥形内螺纹与传统螺纹连接结构的圆锥副的双向锥形内螺纹的内双向锥 形体即锥形孔并非任意锥度或者说任意锥角均可实现螺纹连接副的自锁紧或自 定位， 内圆锥体必须达到一定锥度或者说一定锥角， 双向锥形内螺纹与传统螺 纹连接结构才具备自锁性和自定位性， 所述的锥度包括内螺纹体的左侧锥度和 右侧锥度， 所述的锥角包括内螺纹体的左侧锥角和右侧锥角， 所述的左侧锥度 对应左侧锥角即第一锥角 ocl， 优选地， 所述的 0° <第一锥角 od < 53°， 优选地， 第一锥角 ocl取值为 2°〜 40°， 所述的右侧锥度对应右侧锥角即第二锥角 oc2, 优选 地， 所述的 0° <第二锥角 a2 < 53°， 优选地， 第二锥角 a2取值为 2°〜 40°， 个别特 殊领域， 优选地， 所述的 53%第一锥角 al < 180°， 53%第二锥角 a2 < 180°， 优 选地， 所述的 53%第一锥角 al<90°， 53%第二锥角 a2<90°。
[0022] 上述的个别特殊领域， 是指自锁性要求低甚至不需要自锁性和 /或自定位性要 求弱和 /或轴向承载力要求高和 /或必须设置防抱死措施的传动连接等等螺纹连接 应用领域。

[0025] 所述的双向锥形内螺纹因其螺纹体是锥形体即锥形孔这一独特技术特点和优势 ， 具有较强同化异种螺纹能力， 即具有能够将与之相配合的传统螺纹同化变成 与自己具有相同技术特点和性质的特殊形式锥形螺纹的能力， 被锥形螺纹同化 后的传统螺纹， 即异化传统螺纹， 看上去其螺纹体外形与传统螺纹牙体没有多 大区别， 但已不具传统螺纹之螺纹体实质性技术内容， 其螺纹体由原来传统螺 纹牙体性质变成具有锥形螺纹的螺纹体性质即锥形体性质和技术特点的特殊锥 形几何体， 特殊锥形几何体径向有能与锥形螺纹螺旋状圆锥面相匹配的特殊圆 锥面， 上述的传统螺纹包括三角形螺纹、 梯形螺纹、 锯齿形螺纹、 矩形螺纹、 圆弧螺纹等可以与上述的双向锥形螺纹拧合组成螺纹连接副的其他几何形态螺 纹， 但不局限于上述几种。
[0026] 当传统外螺纹与双向锥形内螺纹配合组成螺纹连接副， 此时的传统外螺纹已非 本来意义上的传统螺纹， 而是一种被锥形螺纹所同化了的特殊形式的锥形螺纹 ， 其与双向锥形内螺纹接触部分形成所述的螺纹连接副的传统外螺纹的特殊锥 形体的能与锥形螺纹螺旋状圆锥面相匹配的外表面， 特殊锥形体上有特殊圆锥 面， 随着拧合使用次数的增加， 传统外螺纹的特殊锥形体上的特殊圆锥面有效 圆锥面面积会不断增加即特殊圆锥面会不断加大并趋向于与双向锥形内螺纹锥 形孔圆锥面有更大接触面方向变化， 实质上形成一种虽然锥形几何形状不完整 但已具备本发明技术精神的特殊锥形体， 进一步地说， 所述的特殊锥形体是传 统外螺纹缘于与双向锥形内螺纹抱合性接触而被其所同化形成的螺纹体， 是由 传统外螺纹牙体转变而来的特殊锥形几何体， 上述的特殊锥形体径向有能与双 向锥形孔圆锥面相匹配的外表面即特殊圆锥面， 即所述的螺纹连接副是由呈螺 旋状的特殊外锥面即传统外螺纹缘于与双向锥形内螺纹接触而构成的特殊锥形 体特殊圆锥面与呈螺旋状的内锥面即双向锥形内螺纹的内圆锥面相互配合构成 圆锥副形成螺纹副， 内圆锥面即内圆锥体的内锥面即双向锥形内螺纹锥形孔的 螺旋状圆锥面为双向圆锥面， 被其同化后的传统螺纹， 是一种异化传统螺纹， 是一种特殊形式锥形螺纹， 这种特殊形式锥形螺纹外圆锥面即传统外螺纹的特 殊圆锥面先以线的形态出现， 并随着传统外螺纹牙尖与双向锥形内螺纹锥形孔 接触使用次数增加而外锥面逐渐增加， 即传统外螺纹的特殊圆锥面是由微观上 的面 （宏观上是线） 到宏观上的面不断变化加大， 也可以直接在传统外螺纹的 牙尖部位加工出与双向锥形内螺纹相匹配的外锥面， 这些都符合本发明技术精 神。

[0078] 本实施例中， 当螺栓六角头部位于右侧， 其结构、 原理以及实施步骤与本实施 例类似。
[0079] 实施例四
[0080] 如图 5所示， 本实施例的结构、 原理以及实施步骤与实施例一和实施例二类似 ， 不同的地方在于， 双螺母与被紧固工件 130的位置关系不同， 所述的双螺母包 括螺母体 21和螺母体 22且螺栓体有大于螺杆体 31的六角头部， 当螺栓六角头部 位于左侧， 螺母体 21、 螺母体 22均位于被紧固工件 130的右侧， 本实施例的螺栓 与双螺母连接结构工作时， 螺母体 21、 螺母体 22与被紧固工件 130之间的关系是 非刚性连接， 所述的非刚性连接是指两个螺母即螺母体 21、 螺母体 22的相向侧 面端面互为支承面， 所述的支承面包括锁紧支承面 111和锁紧支承面 112, 主要 应用于非刚性材料或传动件等非刚性连接工件 130或要通过双螺母安装满足需求 等应用领域。 所述的工件 130是指包括工件 130在内的被连接物体。
[0081] 本实施例的内螺纹 6螺纹工作支承面是不同的， 包括锥形螺纹支承面 121和锥形 螺纹支承面 122 筒状母体 2包括左侧螺母体 21与右侧螺母体 22 左侧螺母体 21 右侧端面即锁紧支承面 111与右侧螺母体 22左侧端面即锁紧支承面 112相向直接 接触并互为锁紧支承面， 当左侧螺母体 21的右侧端面是锁紧支承面 111时， 左侧 螺母体 21双向锥形螺纹 1的左侧螺旋状圆锥面是螺纹工作支承面即锥形内螺纹 6 锥形孔第一螺旋状圆锥面 421和传统外螺纹 9特殊圆锥面 72是锥形螺纹支承面 122 且锥形孔第一螺旋状圆锥面 421与传统外螺纹 9特殊圆锥面 72互为支承面， 当右 侧螺母体 22的左侧端面是锁紧支承面 112时， 右侧螺母体 22双向锥形螺纹 1的右 侧螺旋状圆锥面是螺纹工作支承面即锥形内螺纹 6锥形孔第二螺旋状圆锥面 422 和传统外螺纹 9特殊圆锥面 72是锥形螺纹支承面 121且锥形孔第二螺旋状圆锥面 4 22与传统外螺纹 9特殊圆锥面 72互为支承面。
[0082] 本实施例中， 当位于内侧的筒状母体 2即与被紧固工件 130相邻的螺母体 21已经 与柱状母体 3即螺杆体 31即螺栓有效结合在一起即组成螺纹连接副 10的内螺纹 6 与外螺纹 9有效抱合在一起， 位于外侧的筒状母体 2即与被紧固工件 130不相邻的 螺母体 22可以根据应用工况需要保持原状和 /或拆卸掉而只留一只螺母 （譬如当 装备要求轻量化或不需要双螺母来确保连接技术可靠性等应用领域） ， 被拆除 螺母体 22不作为连接螺母使用而只是作为安装工艺螺母使用， 所述的安装工艺 螺母内螺纹除了是采用双向锥形螺纹 6制造， 还可以是采用单向锥形螺纹以及可 以与螺栓螺纹拧合的其他螺纹即包括三角形螺纹、 梯形螺纹、 锯齿形螺纹等非 锥形螺纹的螺纹制造的螺母体 22, 确保连接技术可靠性前提， 所述的螺纹连接 副 10是一种闭环紧固技术系统即螺纹连接副 10的内螺纹 6与外螺纹 9实现有效抱 合在一起后螺纹连接副 10将自成独立技术系统而不依赖于第三者的技术补偿来 确保连接技术系统的技术有效性即即便没有其他物件的支持包括螺纹连接副 10 与被紧固工件 130之间有间隙也不会影响螺纹连接副 10的有效性， 这将有利于大 大减轻装备重量， 去除无效载荷， 提升装备的有效载荷能力、 制动性能、 节能 减排等等技术需求， 这是当本双向锥形内螺纹与传统螺纹的连接结构的螺纹连 接副 10与被紧固工件 130的关系无论是非刚性连接还是刚性连接时所独具的而其 他螺纹技术不具备的螺纹技术优势。
[0083] 本实施例中， 当螺栓六角头部位于右侧， 则螺母体 21、 螺母体 22均位于被紧固 工件 130的左侧， 其结构、 原理以及实施步骤与本实施例类似。
[0084] 实施例五
[0085] 如图 6所示， 本实施例的结构、 原理以及实施步骤与实施例一和实施例四类似 ， 不同的地方在于， 本实施例是在实施例四的基础上在螺母体 21与螺母体 22之 间增加了垫片 132之类的间隔物， 即左侧螺母体 21的右侧端面与右侧螺母体 22的 左侧端面经垫片 132而相向间接接触由此间接互为锁紧支承面即左侧螺母体 21右 侧端面与右侧螺母体 22左侧端面相互关系由原先直接互为锁紧支承面变成是间 接互为锁紧支承面。
