Abstract

一种滑移式加力扳手,它至少有:驱动部件(1)和手柄(3)构成的扳手,其特征在于:上述的手柄(3)上设置了加力柄(4),在该加力柄(4)的内部设置了抽插槽(6),在该手柄(3)的尾部设置了挡片(5),并且,在上述的抽插槽(6)的开口处设置有与挡片(5)大小相同的凸起(2)。上述手柄(3)与加力柄(4)处于动配合状态。

Description

一种滑移式加力扳手
技术领域:
本发明涉及一种滑移式加力扳手技术。
背景技术:
现今,扳手作为机械修理过程中使用最广泛的工具之一。它具有小巧灵活、使用简便、工作效率高等优点,是机械修理中不可或缺的工具。但是,扳手却存在着手柄尺寸较短的问题,导致它在紧固螺栓、螺帽等作业时所能够输出的扭矩偏小。
发明内容:
本发明的目的是:
弥补现有扳手存在的上述输出扭矩偏小的不足。
为了实现本发明之目的,拟采用以下的技术方案:
本发明至少有:驱动部件和手柄构成的扳手,其特征在于:上述的手柄上设置了加力柄,在该加力柄的内部设置了抽插槽,在该手柄的尾部设置了挡片,并且,在上述的抽插槽的开口处设置有与挡片大小相同的凸起。——上述手柄与加力柄处于动配合状态。
本发明与现有技术比较:
本发明在现有扳手的基础上设置了加力柄,这就为在使用时用较小的手扭力实现较大的扳手扭力的输出创造了条件。
附图说明:
图1是本发明不加力时加力柄处于向内收缩状态的示意图。
图2是图1的侧部剖面图。
图3是本发明加力时加力柄处于向外伸长状态的示意图。
图4是图3的侧部剖面图。
1、驱动部件;2、凸起;3、手柄;4、加力柄;5、挡片;6、抽插槽。
具体实施方式:
本发明是通过在现有扳手的手柄3上设置了加力柄4,以增加扳手的力臂来增大扳手力矩的输出的。又在该手柄3的尾部设置了挡片5,并且,在上述的加力柄4内部的抽插槽6的开口处设置有与挡片5大小相同的凸起2。
本发明一般情况与普通扳手的使用一样,当遇到需要加力时,将加力柄4向着远离驱动部件1的方向滑移,直到设置在加力柄4内部的抽插槽6开口处的凸起2被设置在手柄3尾部的挡片5阻挡不能继续滑移。
显然,此时的本发明增加了扳手的力臂,这就为人们在使用时用较小的手扭力实现较大的扳手扭力的输出创造了条件。
