Abstract

一种倒装式打击工具,它在柄部设计一梯形榫,金属头上开有与之配合的梯形孔,将金属头装入后,梯孔榫与梯形孔密合,使金属头部不易从工具柄上滑脱,该结构广泛用于木质、金属、玻璃纤维、碳纤维等各类工具柄中,大大提高了打击工具的冲击力和安全系数。

Description

倒装式打击工具
本实用新型涉及工具领域,特别是一种工具头部与柄的倒装式结构。
目前,市场上销售、工厂生产及人们使用的打击工具,如:八角锤、石工锤、羊角锤、锤斧、木工斧等工具,其柄与头部均采用常规的装配方式,即在柄顶端做成方榫或椭园榫,然后装上金属头部的孔中,为使头部不致脱落,采用强制紧配合方法(即强制性将柄的榫打入金属头的孔中)或用粘结力很强的胶粘合,以尽量使其金属头部不易脱落,但在使用过程中,工具头部脱落的现象仍时有发生,有的还会造成事故。
本实用新型的目的在于:设计一种倒装式柄与金属头的结构,使其施以很大的冲击力也不会使金属部头从柄上滑脱。
本实用新型的技术方案是:在木质、金属、玻纤或碳纤维工具柄的端部制作一梯形榫,使梯形的底位于柄的顶端,并大于柄的最宽部,金属头的孔部也制作成与之相吻合的梯形孔,将金属头部从柄尾装向柄端部,使金属头的梯形孔与柄的梯形榫密合,然后在柄部套入带直线与曲线相交凹槽的橡胶护套,提高防滑和耐磨力。
图1为本实用新型结构示意图
图中:1工具柄梯形榫、2工具柄、3橡胶护套、4金属头部梯形孔、5金属头、6密封胶。
下面结合附图进一步介绍本实用新型的技术内容及实施方法:
工具柄2的端部有一梯形榫1,金属头5开有与榫1相配合的梯形孔4,将金属头5从工具柄2的尾部套向梯形榫1,使孔4牢牢套在榫1上,为使柄与金属部不留缝隙,在梯形孔4外部涂上密封胶6,将带有直线与曲线相交凹槽的橡胶套3套入柄2上。
本实用新型有以下优点及效果:一是装配简单;二是提高了金属头与柄之间的脱落拉力。经试验,原设计纤维柄金属头部与柄之间可承受2吨的拉力,现在可达到10吨,基本上达到金属头部与柄在正常使用中不会脱落的要求,有很高的安全系数。
