具体实施方式
实施例 1 :
一种快速调节防滑活扳手实施例， 参见图 1至图 8, 如图 1所示所述扳手由 扳体 1、 活动扳头 2、 偏心键 3、 弹簧 4组成， 扳体的前端是固定扳头 101 , 扳 体的后端是手柄 102, 活动扳头上有工件夹持面 210, 固定扳头上有工件夹持面 107 , 活动扳头与固定扳头分别设置有键槽和键， 键槽的轴向中心线和键的轴向 中心线相互平行， 活动扳头键 201插入固定扳头键槽 103 , 同时固定扳头键 104 插入活动扳头键槽 202,实现活动扳头与固定扳头之间利用凹凸键槽方式滑动配 合连接， 在所述活动扳头键槽开口上边沿一侧向键槽内侧设有凸出块 203 , 所述 凸出块扣住所述固定扳头键防止活动扳头与固定扳头脱落； 如图 3所示， 所述 活动扳头上设置有偏心键槽 204,偏心键槽与活动扳头键以及活动扳头键槽交叉 相切设置； 如图 6所示， 所述偏心键是一个有上下平面 301的偏心键体， 在偏 心健体上平面的一端有一个向上的凸起形成偏心键凸台 302,所述偏心健体下平 面上设置有扳钮 303 , 所述扳钮设置在偏心键凸台凸起的反面； 如图 1、 图 2和 图 4所示， 所述偏心键安装在偏心键槽中， 偏心键凸台与活动扳头键一同插入 固定扳头键槽， 偏心键扳钮突出在扳体表面， 所述弹簧设置在活动扳头键侧端 面 205与偏心键之间， 弹簧推动偏心键在偏心键槽中偏转， 偏心键凸台卡住固 定扳头键槽阻止活动扳头键在固定扳头键槽中滑动。
实施例中所述活动扳头键侧端面 205设置有弹簧定位孔 209,所述偏心键与 弹簧接触的端面也设置有弹簧定位孔 309,所述弹簧分别插入活动扳头键侧端面 弹簧定位孔和偏心键弹簧定位孔，弹簧通过定位孔定位在活动扳头键侧端面 205 与偏心键之间。
本实施例所述偏心键槽与活动扳头键以及活动扳头键槽呈 90度角交叉相切 设置。
如图 3所示， 所述偏心键槽是开放式的贯穿活动扳头键延伸至活动扳头键 槽， 偏心键槽顶端 206呈半圓形面， 偏心键槽与所述活动扳头键端面 205不相 邻的另一侧面 207呈扇形向外侧倾斜， 倾斜角度 208根据扳手的大小而不同， 通常是 5度到 30度， 本实施例倾斜角是 10度。
如图 1、 图 6和图 7所示， 所述偏心键凸台与固定扳头键槽侧面 105接触的 端面 304是弧面， 在偏心键凸台与固定扳头键槽另一侧面 108接触的端面 306 是弧面， 所述偏心键凸台两个相对弧面的最高面之间垂直线距离 307小于固定 扳头键槽的宽度 106 , 所述垂直线与所述偏心键上下平面的侧面 305平行， 同时 所述偏心键凸台两个相对弧面的最高面之间直线距离 308大于固定扳头键槽的 宽度 106。
实施例中所述的偏心键槽是一开放键槽， 偏心键槽内嵌入了偏心键和一个 弹簧， 它们之间的连接配合使得活动扳头具有了偏心自锁功能。 自锁的原理是: 偏心键槽顶端呈半圓形面； 偏心键与偏心键凸台不相邻的另一端呈半圓形弧面， 偏心键的半圓形弧面与偏心键槽的半圓形面的半径相同， 由于偏心键槽与所述 活动扳头键端面 205不相邻的另一侧面 207呈扇形向外侧倾斜， 使得所述偏心 键凸台与固定扳头键槽侧面 105接触的弧面 304可以在键槽内以键槽的半圓形 面的圓心为中心摆动， 拨动扳钮可以使偏心键在偏心键槽内转动用以释放活动 扳头偏心自锁的功能。
实施例 2:
一种快速调节防滑活扳手另一实施例， 参见实施例 1、 图 9、 图 10和图 11 , 为了使活动扳头与固定扳头分别设置有的键槽和键相互配合流畅， 在加工中须 留有一定的公差配合尺寸， 在使用中就会出现活动扳头与固定扳头之间滑动时 出现晃动， 这样在实际的夹持工件时就会出现活动扳头的工件夹持面与固动扳 头的工件夹持面相互不平行， 为了克服所述公差配合尺寸而出现的这种现象， 如图 9所示， 所述的活动扳头工件夹持面向活动扳头内侧倾斜， 倾斜的角度 214 是 3度至 10度。 本实施例倾斜的角度是 5度。 在实施例 1时， 活动扳头键槽的 轴向中心线 211和键的轴向中心线 212与固定扳头键的轴向中心线和键槽的轴 向中心线重合， 固定扳头键的轴向中心线和键槽的轴向中心线与固定扳头的工 件夹持面的夹角是 90度， 因此活动扳头键槽的轴向中心线 211和键的轴向中心 线 212与活动扳头工件夹持面夹角是 90度。 在本实施例中， 由于所述的活动扳 头工件夹持面向活动扳头内侧倾斜， 倾斜的角度 214是 3度至 10度， 因此活动 扳头键槽的轴向中心线 211和键的轴向中心线 212与活动扳头工件夹持面夹角 213变为是 93度至 100度； 图 11示意了本实施例活动扳头的工件夹持面与固动 扳头的工件夹持面在未夹持工件合拢时的状态， 为了利用所述的公差， 如图 9 和图 10所示， 此时在活动扳头键的外侧顶角和与之相对的对角分别设置有倒角 215和 216, 在所述活动扳头键槽开口上边沿一侧向键槽内侧设有的凸出块 203 的外顶角设置有倒角 217 , 以及所述活动扳头键槽远离活动扳头键的一侧外侧角 设置有倒角 218; 倒角的大小根据扳手的大小而不同， 其倒角的目的作用是配合 活动扳头倾斜的工件夹持面， 当该工件夹持面夹持到工件时， 倒角利用加工公 差向背离固定板头夹持面方向倾斜， 此时的活动扳头倾斜的工件夹持面正好校 正过来与固定扳头的工件夹持面平行， 将工件夹的更紧不滑动。
上述实施例快速调节防滑活扳手的工作原理是， 当需要打开夹持面时， 拨 动位于偏心键上的扳钮使偏心键在偏心键槽内转动， 此时， 由于偏心键凸台与 固定扳头键槽侧面 105接触的端面 304顶端与偏心键凸台另一端面 306顶端的 垂直距离小于凹形槽的宽度， 活动扳头得以在固定扳头键槽内自由移动； 当释 放扳钮， 在没有外力对偏心键上的扳钮施压的情况下， 由于弹簧的张力使得偏 心键凸台与固定扳头键槽侧面 105接触的端面 304顶端与偏心键凸台另一端面 306顶端分别 4氏在固定扳头键槽的上壁 108和下壁 105上，此时活动扳头就不能 在固定扳头键槽内自由移动， 当夹持工件时， 活动扳头向远离固定扳头方向受 力越大， 活动扳头的自锁力量越大， 加上所述位于活动扳头键、 凸出块 203及 活动扳头键槽上的倒角 215、 216、 217和 218的配合， 绝对不会发生向远离固 定扳头方向移动的现象， 当需要闭合钳口时只需推动活动扳头外侧底部即可。
