Description

棘轮工具
技术领域
本发明涉及一种手动工具，更具体地说，涉及一种 棘轮工具。
背景技术
螺丝批是一种用来拧转螺丝钉以迫使其就位的工具，包括批杆和手柄。现有的螺丝批，批杆通常与手柄固定在一起，使用时，由于握持手柄的手只能够转动一个较小的角度。因此，当需要对一个零件连续多次旋动时，其间需要停顿下来让手反方向回转一个角度：一种方法是手持螺丝批从零件上暂时撤离实现反方向回转，这种方式需要再次将螺丝批对准零件；另一种方法是用另一只手辅助让握持手柄的手松开手柄实现反方向回转。显然的，这两种方法均存在不便，影响作业效率；也容易将螺丝头拧坏。
为了克服上述不足，定向手动螺丝批应需而生，这种手动螺丝批的'定向'功用是向一个方向旋转手柄时令手柄携带着工作杆一起转动以便向零件施加扭矩，向另一个方向旋转手柄时令手柄相对工作杆转动，将工作杆定位在零件上，因此可以用手握持着手柄连续的来回旋转，其间不需停顿，达到快速旋紧或者旋松零件的目的，进一步的，这种动作是可以换向的。
中国ZL 201010184827.4公开了一种棘轮螺丝批，包括手柄和批杆，手柄的前端具有棘爪座，棘爪座上设置两个反向的可摆动的棘爪以及用于控制该两个棘爪位置状态的拨件，拨件上具有两个分别对应上述两个棘爪的拨块，批杆的末端具有棘轮套，该棘轮套套在所述棘爪座上且至少与所述两个棘爪中的一个啮合，并设一可在所述的手柄上定位的操控件用于变换所述拨件的位置。经分析及实践验证，上述棘轮螺丝批存在以下缺陷：
1 、采用棘轮套上的轴孔与棘爪座上向前延伸至轴孔内的轴段相配合，导致批杆与棘爪座的配合面很少，批杆相对棘爪座晃动厉害，拧转螺丝钉效果差。
2 、棘爪与棘轮套啮合的齿数少，传递扭矩的能力小。
3 、棘轮的齿数较少，在回转时所需回转力较大，这样在拧一些预紧力不大的螺丝批时，'定向'功能不能很好的实现。
因此，市场上需要一种既 解决批杆晃动问题 ，又有效率的螺丝批。
另外，由于棘轮螺丝批使用范围广，在光线不足或者较黑暗的场合使用时，常常需要借用额外的照明设备，这就为操作带来了不便。因此，市场上需要一种兼具照明功能的棘轮螺丝批。

具体实施方式
实施例一
图1-图15显示了本发明一较佳实施例的相关结构示意图。
如图1-图3所示，本发明的棘轮工具包括杆组件1、手柄2、和棘轮装置3。手柄2与棘轮装置3连接，杆组件1沿着棘轮装置3的中心轴从棘轮装置3的前端延伸到棘轮装置3的内部并与棘轮装置3连接。在本实施例中，杆组件1优选沿着棘轮装置3的中心轴从棘轮装置3的前端延伸穿过棘轮装置3的末端并与棘轮装置3连接。
其中，杆组件1进一步包括批杆11和延伸部12，在本实施例中，批杆11与延伸部12设计成一体成型，延伸部12延伸到棘轮装置3的内部，延伸部12沿着 棘轮装置3的中心轴从棘轮装置3的前端穿过棘轮装置3的末端并与棘轮装置3连接。杆组件1更清晰的结构如图6所示，批杆11的末端具有键槽14，键槽14可以设计成单个，也可以成对设计并位于批杆11相对应的两侧（如图7所示），键槽14与棘爪套31相匹配，用以牢固固定批杆11与棘爪套31，使扭矩在传递时批杆11相对于棘爪套31不晃动。
杆组件1远离手柄的一端具有一工作部4，以输出扭矩。工作部4具体可以是安装在杆组件1远离手柄的一端上的各种型号的批头（如图1所示），如一字批头、梅花批头、内六角批头等；工作部4还可以是各种型号的套筒，套筒与杆组件1可以设计成一体成型（如图8所示），也可以通过一连接件41与杆组件1连接（如图9所示），连接件41可以用来安装各种型号的套筒。
批杆11的直径大于延伸部12的直径，延伸部12的末端具有轴槽15，相应的设计了与该轴槽15相配合的紧固环13（如挡圈）。当延伸部12穿过棘爪座36的内孔时，在轴槽15处卡上与之相配合的紧固环13。由于批杆11的直径大于延伸部12的直径，并结合轴槽15与紧固环13的配合使用，使得棘爪座36牢牢固定在杆组件上，不发生轴向移动。另外，杆组件1 与棘轮装置3的这种连接方式，使得杆组件1与棘爪座36的内孔形成了一个很长的配合面，增加了杆组件1与棘爪座36的接触面积，这样就解决了在使用该棘轮工具时 批杆11相对棘爪座36晃动的问题，拧转效果好。
在本实施例中，以任意方向（顺时针或逆时针均可）在手柄2输入的扭矩被传递到杆组件1，使杆组件1以预设的方向（顺时针或逆时针之一）输出扭矩。
如图4-图6所示，棘轮装置3包括设置在杆组件1上并被杆组件1 沿中心轴 穿过的棘爪座36，棘爪座36上沿中心轴两侧对称设置两个可摆动的第一棘爪351和第二棘爪352，和用于控制两个棘爪位置状态的换向元件33。换向元件33上具有第一阻挡块331和第二阻挡块332，第一阻挡块331对应于第一棘爪351、第二阻挡块332对应于第二棘爪352，第一棘爪351和第二棘爪352、第一阻挡块331和第二阻挡块332的外部设有棘爪套31。
棘爪套31的内壁具有环状分布的内棘齿311，棘爪套31套在第一棘爪351、第二棘爪352上，其内棘齿311与第一棘爪351、第二棘爪352上的齿相咬合。棘爪套31的外侧还设有与换向元件33相连的定位装置32，定位装置32也可与换向元件33一体连接。定位装置32具体为转套，为一环状套套在棘爪套31的外侧。如图10和图11所示为定位装置32处于中间位置时。
当转动定位装置32的时候，换向元件33随之移动，换向元件33上的第一阻挡块331和第二阻挡块332也随之移动。如图12和13所示，当顺时针转动定位装置32时，第二阻挡块332挤压第二棘爪352脱离棘爪套31的内棘齿311，第一棘爪351继续与棘爪套31的内棘齿311相啮合，此时，顺时针方向转动手柄能够将来自手柄的扭矩通过棘爪座36、与棘爪套31啮合的第一棘爪351、棘爪套31传递给批杆，逆时针方向转动手柄则与棘爪套31啮合的第一棘爪351可被棘爪座36带动从棘爪套31的内棘齿311上滑过，不向批杆传递扭矩，令手柄回转。如图14和15所示，当逆时针转动定位装置32时，第一阻挡块331挤压第一棘爪351脱离棘爪套31的内棘齿311，第二棘爪352继续与棘爪套31的内棘齿311相啮合，此时，逆时针方向转动手柄能够将来自手柄的扭矩通过棘爪座36、与棘爪套31啮合的第二棘爪352、棘爪套31传递给批杆，顺时针方向转动手柄则与棘爪套31啮合的第二棘爪352可被棘爪座带动从棘爪套31的棘齿上311滑过，不向批杆传递扭矩，令手柄回转。无论转套转至图中的任一位置，均通过定位而保持在该位置上。
进一步，第一棘爪351和第二棘爪352之间支撑有令该两个棘爪张开靠向棘爪套的第一弹性元件37，换向元件33上的第一阻挡块331位于对应的第一棘爪351的外侧，换向元件33上的第二阻挡块332位于对应的第二棘爪352的外侧。由此保证第一棘爪351、第二棘爪352与棘爪套31啮合。
另外，第一棘爪351通过第一销轴341连接在棘爪座36上，第二棘爪352通过第二销轴342连接在棘爪座36上。由此保证第一棘爪351、第二棘爪352能够灵活摆动，同时还能够保证棘爪具有足够的传递扭矩的能力。
如图10-15所示，转套内壁具有第一定位槽324、第二定位槽325和第三定位槽326，棘爪座36上设有定位弹子321，定位弹子321由第二弹性元件323支撑位于第一定位槽324、第二定位槽325和第三定位槽326中的一个内，从而实现转套在手柄上的定位，根据该结构，当转套位于如图10和图11所示状态时，定位弹子321位于转套上的第二定位槽325内，此时第一棘爪351、第二棘爪352位于如图11所示状态。当转套位于如图12和图13所示状态时，定位弹子321位于转套上的第三定位槽326内，此时第一棘爪351、第二棘爪352位于如图13所示状态。当转套位于如图14和图15所示状态时，定位弹子321位于转套上的第一定位槽324内，此时第一棘爪351、第二棘爪352位于如图15所示状态。
如图10或11所示，棘爪座36具有槽361，换向元件33位于槽361内，转套与换向元件33之间靠紧固件322连接（如螺钉）。由此在实现由转套带动换向元件33的同时，还通过将换向元件33限制在槽361内不能在轴向移动来实现对转套的约束，即通过紧固件322禁止转套脱离工作位置。
为了进一步减小回转时所需的回转力，更好地实现'定向'功能，本发明对 棘轮套31的 内棘齿 311 的齿数 做了进一步改进，本实施例中内棘齿311的齿数多于60个，优选≥72个（例如72个）。
同时，为了增大传递扭矩的能力，本发明增加 了 第一和第二 棘爪 与棘轮套31啮合的齿数，本实施例中，第一和第二棘爪的齿数被设置为多于3个，优选 ≥ 5 个 （例如5个），相应地， 棘轮套31的 内棘齿311的齿数，在满足多于60个的前提下，被设置成与 第一和第二棘爪的齿数相匹配。
实施例二
本实施例与实施例一类似，主要区别是杆组件的结构。
在该实施例中，杆组件 具有远离手柄的第一端和靠近手柄的第二端，以及位于第一端和第二端之间的中间部，该中间部的半径大于由该中间部向两边延伸的部分的半径。当杆组件的第一端伸到棘轮装置的内部时，套上棘爪套，由于中间的半径大，这样便能够实现杆组件在轴向上的固定；相应地，当杆组件拔出，换成杆组件的第二端伸到棘轮装置的内部时，套上棘爪套，同样能够实现杆组件在轴向上的固定。
其中，杆组件的第一端具体可以是一工作部 ，如套筒、安装套筒的连接件、各种型号的批头（如内六角批头、十字披头等）等，杆组件的第二端具体也可以是一工作部，如套筒、安装套筒的连接件、各种型号的批头（如内六角批头、十字披头等）等，其中，优选地，第一端实现的功能与第二端实现的功能不一致，即杆组件的第一端和第二端具有两种不同的功能。当杆组件的第一端位于棘轮装置内时，该棘轮工具具有一种功能，当将杆组件拔出换向使用，即杆组件的第二端位于棘轮装置内时，该棘轮工具具有另一种功能。杆组件的这种设计，实现了杆组件的自由拆卸和换向使用，进而使一件棘轮工具具有两种不同的功能。
实施例三
图1、图4、图10-21显示了本发明另一较佳实施例的相关结构示意图。
本实施例与实施例一类似，主要区别是杆组件1的结构。
如图16所示，棘轮工具包括杆组件1、手柄2、和棘轮装置3。手柄2与棘轮装置3连接，杆组件1沿着棘轮装置3的中心轴从棘轮装置3的前端延伸到棘轮装置3的内部并与棘轮装置3连接。在本实施例中，杆组件1优选沿着棘轮装置3的中心轴从棘轮装置3的前端延伸穿过棘轮装置3的末端并与棘轮装置3连接。
其中，杆组件1进一步包括批杆11和延伸部12，在本实施例中，批杆11与延伸部12独立设计，延伸部12延伸到棘轮装置3的内部，延伸部12沿着 棘轮装置3的中心轴从棘轮装置3的前端穿过棘轮装置3的末端并与棘轮装置3连接。杆组件1更清晰的结构如图18和19所示，批杆11具有一六角轴端111，六角轴端111与棘爪套31相匹配，六角轴端111穿过棘爪套31，用以牢固固定批杆11与棘爪套31，使扭矩在传递时批杆11相对于棘爪套31不晃动。
批杆11远离手柄的一端具有一工作部4，以输出扭矩。工作部4具体可以是安装在批杆11远离手柄的一端上的各种型号的批头（如图16所示），如一字批头、梅花批头、内六角批头等；工作部4还可以是各种型号的套筒，套筒与杆组件1可以设计成一体成型（如图20所示），也可以通过一连接件41与杆组件1连接（如图21所示），连接件41可以安装各种型号的套筒。
延伸部12的末端具有轴槽15，相应的设计了与该轴槽15相配合的紧固环13（如挡圈）。当延伸部12穿过棘爪座36的内孔时，延伸部12与六角轴端111紧紧相贴，并在轴槽15处卡上与之相配合的紧固环13 。由于六角轴端111与棘爪套31的相互配合，并结合轴槽15与紧固环13的配合使用，使得棘爪座36牢牢固定在杆组件上，不发生轴向移动。另外，杆组件1 与棘轮装置3的这种穿轴式连接方式，使得杆组件1与棘爪座36的内孔形成了一个很长的配合面，增加了杆组件1与棘爪座36的接触面积，这样就解决了在使用该棘轮工具时 批杆11相对棘爪座36晃动的问题，拧转效果好。
在本实施例中，以任意方向（顺时针或逆时针均可）在手柄2输入的扭矩被传递到杆组件1，使杆组件1以预设的方向（顺时针或逆时针之一）输出扭矩。
如图4、图18所示，棘轮装置3包括设置在杆组件1上并被杆组件1沿中心轴穿过的棘爪座36，棘爪座36上沿中心轴两侧对称设置两个可摆动的第一棘爪351和第二棘爪352，和用于控制两个棘爪位置状态的换向元件33。换向元件33上具有第一阻挡块331和第二阻挡块332，第一阻挡块331对应于第一棘爪351、第二阻挡块332对应于第二棘爪352，第一棘爪351和第二棘爪352、第一阻挡块331和第二阻挡块352的外部设有棘爪套31。
棘爪套31的内壁具有环状分布的内棘齿311，棘爪套31套在第一棘爪351、第二棘爪352上，其内棘齿311与第一棘爪351、第二棘爪352上的齿相咬合。棘爪套31的外侧还设有与换向元件33相连的定位装置32，定位装置32也可与换向元件33一体连接。定位装置32具体为转套，为一环状套套在棘爪套31的外侧。定位装置32处于中间位置时，如图10和图11所示。
当转动定位装置32的时候，换向元件33随之移动，换向元件33上的第一阻挡块331和第二阻挡块332也随之移动。如图12和13所示，当顺时针转动定位装置32时，第二阻挡块332挤压第二棘爪352脱离棘爪套31的内棘齿311，第一棘爪351继续与棘爪套31的内棘齿311相啮合，此时，顺时针方向转动手柄能够将来自手柄的扭矩通过棘爪座36、与棘爪套31啮合的第一棘爪351、棘爪套31传递给批杆，逆时针方向转动手柄则与棘爪套31啮合的第一棘爪351可被棘爪座36带动从棘爪套31的内棘齿311上滑过，不向批杆传递扭矩，令手柄回转。如图14和15所示，当逆时针转动定位装置32时，第一阻挡块331挤压第一棘爪351脱离棘爪套31的内棘齿311，第二棘爪352继续与棘爪套31的内棘齿311相啮合，此时，逆时针方向转动手柄能够将来自手柄的扭矩通过棘爪座36、与棘爪套31啮合的第二棘爪352、棘爪套31传递给批杆，顺时针方向转动手柄则与棘爪套31啮合的第二棘爪352可被棘爪座带动从棘爪套31的棘齿上311滑过，不向批杆传递扭矩，令手柄回转。无论转套转至图中的任一位置，均通过定位而保持在该位置上。
进一步，第一棘爪351和第二棘爪352之间支撑有令该两个棘爪张开靠向棘爪套的第一弹性元件37，换向元件33上的第一阻挡块331位于对应的第一棘爪351的外侧，换向元件33上的第二阻挡块332位于对应的第二棘爪352的外侧。由此保证第一棘爪351、第二棘爪352与棘爪套31啮合。
另外，第一棘爪351通过第一销轴341连接在棘爪座36上，第二棘爪352通过第二销轴342连接在棘爪座36上。由此保证第一棘爪351、第二棘爪352能够灵活摆动，同时还能够保证棘爪具有足够的传递扭矩的能力。
如图10-15所示，转套内壁具有第一定位槽324、第二定位槽325和第三定位槽326，棘爪座36上设有定位弹子321，定位弹子321由第二弹性元件323支撑位于第一定位槽324、第二定位槽325和第三定位槽326中的一个内，从而实现转套在手柄上的定位，根据该结构，当转套位于如图10和图11所示状态时，定位弹子321位于转套上的第二定位槽325内，此时第一棘爪351、第二棘爪352位于如图11所示状态。当转套位于如图12和图13所示状态时，定位弹子321位于转套上的第三定位槽326内，此时第一棘爪351、第二棘爪352位于如图13所示状态。当转套位于如图14和图15所示状态时，定位弹子321位于转套上的第一定位槽324内，此时第一棘爪351、第二棘爪352位于如图15所示状态。
如图10或11所示，棘爪座36具有槽361，换向元件33位于槽361内，转套与换向元件33之间靠紧固件322连接（如螺钉）。由此在实现由转套带动换向元件33的同时，还通过将换向元件33限制在槽361内不能在轴向移动来实现对转套的约束，即通过紧固件322禁止转套脱离工作位置。
为了进一步减小回转时所需的回转力，更好地实现'定向'功能，本发明对棘轮套31的 内棘齿311的齿数做了进一步改进，本实施例中内棘齿311的齿数多于60个，优选≥72个（例如72个）。
同时，为了增大传递扭矩的能力，本发明增加了第一和第二棘爪与棘轮套31啮合的齿数，本实施例中，第一和第二棘爪的齿数被设置为多于3个，优选 ≥ 5 个 （例如5个），相应地， 棘轮套31的 内棘齿311的齿数，在满足多于60个的前提下，被设置成与 第一和第二棘爪的齿数相匹配。
实施例四

从附图中可以看出，本实施例与实施例一类似，主要区别是增加了照明装置。
本实施例在实施例一的基础上增加了照明装置，照明装置的具体位置如图23所示。定位装置32具体为转套，为一环状套套在棘爪套31的外侧，在本实施例中，定位装置32具有一内腔321，用以安装照明装置。如图24和25所示，照明装置包括电路板5和安装在该电路板上的电源7，当照明装置安装固定在定位装置32的内腔321中时，透明盖6盖合并固定于定位装置32上，实现了照明的功能。
