Description

棘轮扳手 技术领域
本发明涉及一种棘轮扳手。
背景技术
扳手是生产活动中常用的工具，其具有各种各样的功能，包括活动扳手、套筒扳手等。但在一些空间狭窄的场合，使用这些扳手有时候感到不方便，因为拧紧一个螺栓或螺母需要转动很多圈，而普通的扳手不能转动360度，需要将扳手从螺栓或者螺母上取下，然后再选择合适的角度重复动作，这样的扳动不但过程复杂，效率低下，而且可能造成螺栓或者螺母的回转，使松紧螺栓或者螺母非常不方便。
因此出现了一些棘轮扳手，可以控制扳手只作单方向的运动而不会造成回转。如中国专利CN2389754Y所公开的“棘轮扳手”，该棘轮扳手在扳手的头部设有一容置孔，其内设有棘轮，扳手设一容纳制齿的容置槽，容置槽末端设有一容珠孔，其内设有弹簧及钢珠，钢珠抵顶制齿，该棘轮扳手，虽然结构简单，而且能够实现制齿的单向旋转，但是该棘轮扳手通过钢珠和制齿的结构控制该棘轮扳手，只能控制该棘轮扳手向左或者向右空转，也就是说该棘轮扳手只有两档控制功能，并没有中间档，也就是说该棘轮扳手只能向右空转或者向左空转，并不能固定在中间档不会空转。并且这样的棘轮扳手在档位转换时不是非常明显而且不易控制。而且这样的棘轮扳手加工比较复杂，不利于提高生产速度以及量产。
另外传统的棘轮扳手，很大一部分扳手头部有一面是不穿空的，通常是采用数控设备加工出来，所以造成生产成本高，生产效率低的问题，需要做改进设计。
发明内容
本发明所要解决的技术问题是提供一种便于安装拆卸，并且加工方便，便于量产的棘轮扳手。
本发明解决上述技术问题所采用的技术方案为：一种棘轮扳手，包括头部，与头部相连的手柄以及位于头部内的齿轮件和制动组件，其特征在于：
所述头部上设有一贯穿其厚度方向、冲裁出来的通孔，通孔的两端分别固定有上挡片和下挡片，所述上、下挡片与通孔形成一容置齿轮件和制动组件的容置空间；
所述制动组件位于所述通孔内靠近所述手柄的一侧端，并且该制动组件包括中间控制块以及位于中间控制块两侧的左、右控制片，该左、右控制片与所述通孔的侧面之间 分别抵有弹簧，所述左、右控制片的端部分别从左、右两侧卡住该齿轮件。
为了便于控制，所述中间控制块的一端连接一方向拨动钮，所述上挡片上设有与所述中间控制块相匹配的孔，所述中间控制块从所述上挡片的孔中插入至通孔内，并且所述方向拨动钮露出位于所述上挡片外侧。

图2为沿图1中A-A线的剖视图。

图4为沿图1中B-B线的剖视图(单向锁定状态)。

具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1-5所示，本发明实施例的棘轮扳手，包括头部，以及与头部相连的手柄2，头部1上设有一贯穿其厚度方向、冲裁出来的并且容置齿轮3件和制动组件的通孔11，通 孔11的两端，即上方和下方分别设有上安装槽12和下安装槽13，分别容置上挡片6和下挡片7，该上挡片6和下挡片7分别从上下两侧封住该通孔11，使通孔内形成一容置空间容置齿轮件3和制动组件。
所述齿轮件3的上方和下方分别从上挡片6和下挡片7相对应的孔中露出，并且其中一端具有连接头32用于扳手运动时连接螺母。该齿轮件3的周面为齿轮面，位于通孔11内，制动组件位于所述通孔11内靠近手柄2的一侧端。制动组件包括左右两片制动片41、42，以及位于左、右制动片41、42之间的中间控制块43，该左、右制动片41、42与通孔11的侧面之间各抵有一弹簧51、52。通孔11的左右侧，分别有容置左、右控制片41、42的左、右容置部位111、112，左、右容置部位111、112的中间部位呈圆弧形向通孔11外侧突出，该圆弧形中间部位用于容置左、右控制片41、42与通孔11之间的弹簧51、52。通孔11靠近手柄2的一侧分别设有两个定位凹槽15用于容置左、右制动片41、42的一端，该左、右制动片41、42的另一端向着所述齿轮件3延伸并且与齿轮件3上的齿轮面相配合控制。
中间控制块43在中间位置时，如图3所示，左、右制动片41、42由于弹簧51、52的作用远离通孔11的左、右容置部位111、112，因此，左、右控制片41、42正好卡住通孔11中的齿轮件3，使齿轮件3不能相对于通孔转动，也就是说不能相对于该棘轮扳手转动，此时，该棘轮扳手相当于普通扳手，连接于连接头32的螺母通过扳手的转动跟着转动。
当该中间控制块43转向右边或者左边时，如图4所示，该中间控制块43转向左边，并且压缩左控制片41与通孔11之间的弹簧51，此时，左控制片41退回到通孔11的一侧，位于通孔11左侧的容置部位111内，此时，左控制片41解除了对齿轮件32的锁定，但是右控制片42仍旧抵住了齿轮件32，此时齿轮件3只能相对于通孔11逆时针方向转动，因为当齿轮件逆时针方向转动时，由于右控制片42与通孔11抵有弹簧，齿轮件3能够驱动右控制片42压缩弹簧52并且逆时针方向转动，而齿轮件3顺时针转动时，右控制片42抵住了齿轮件32使其不能转动。也就是说扳动扳手，当扳手逆时针转动的时候，齿轮件3以及连接在连接头32上的螺母或者螺栓由于右控制片42的锁定作用会跟着扳手逆时针转动，而扳手顺时针转动时，齿轮件3以及连接在连接头32上的螺母或者螺栓可以相对于通孔11逆时针转动，不会跟着扳手回转，因此实现了扳手的顺时针空转，可以快速并且小空间内扳动扳手松紧螺钉。同理，当中间控制块43转向右边时，当扳手顺时针转动时，齿轮件3以及连接在连接头32上的螺母或者螺栓会跟着扳手顺时针转动，而扳手逆时针转动时，齿轮件3以及连接在连接头32上的螺母或者螺栓不会跟着扳手回转，因此实现了扳手的逆时针空转。
所述中间控制块43的一端连接一方向拨动钮45，并且上挡片6上设有与该中间控制块43位置相匹配的孔，该中间控制块4的中心设有从下向上延伸并与中间控制块4的轴向同向的凹孔，该下挡片7上设有与该凹孔相匹配的开孔72，该中间控制块43通过上挡片6 上对应的孔插入至通孔11内，并且该方向拨动钮45位于所述上挡片6外侧。
所述上挡片上还设有至少一个螺孔61，优选地为两个螺孔61，分别连通至通孔11，所述下挡片7上设有与该螺孔61相对应的螺孔71，螺钉8从上挡片的螺孔61中插入至通孔11，并且通过螺纹与下挡片7上的螺孔71相固定连接，进而固定上挡片6和下挡片7。并且以连接螺钉9从下挡片7上的开孔72插入于所述中间控制块43中的凹孔，进而连接中间控制块43与下挡片7，并且中间控制块43可绕该连接螺钉9转动。
优选地，该中间控制块43的截面为一楔形，其具有分别顶住左、右制动片的两侧平面，以及位于底部的弧形的底面，该底面便于该中间控制块3在左右两个方向转动。
该棘轮扳手，在加工时，只要分别将齿轮件、左右制动片以及中间控制块和方向拨动钮等部件制作出来，然后放入扳手头部的通孔内，扳手手柄锻打后，扳手头部在制作时只要利用冲裁工艺制成一上下大小一致的通孔，然后在通孔两端加工出安装槽即可，上下挡片也只要分别加工出来，这样每个部件的加工都非常简单，加工速度也较快。在安装时，只要将齿轮件、制动组件放入通孔中，然后放上上下挡片，然后通过螺钉8将上下挡片固定，然后将中间控制块4与方向拨动钮45从上档片中插入，然后将连接螺钉9从下挡片7中向上插入于中间控制块4连接，接口完成安装。拆卸时只要反向重复上述动作即可，这样的结构，安装拆卸也非常简单，万一其中之一产生问题，也只要拆开进行更换即可。
该棘轮扳手，不但加工方便，而且安装拆卸也非常方便，易于该棘轮扳手的量产，提高生产效率，也便于更换零件，延长了该棘轮扳手的寿命。
尽管以上详细地描述了本发明的优选实施例，但是应该清楚地理解，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
