Description

一种锤击式钉枪
技术领域
本发明涉及打钉工具, 特别涉及锤击式钉枪。
背景技术
在日常生活中，锤击式钉枪是用于将比较薄的材料紧固到诸如木板、塑料和复合板等类似材料上的工具。在使用过程中，锤击式钉枪的头部撞击工件，带动内部的击发结构将钉子撞击到工件里。
常规的锤击式钉枪在使用过程中，手柄震动明显，会引起操作者手部的不适，同时其结构复杂，装配繁琐。因此现有技术中需要提供一种结构简单、装配方便的能缓解操作者手部不适的锤击式钉枪。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供一种结构简单、装配方便的能缓解操作者手部不适的锤击式钉枪。
为实现上述目的，本发明首先提供了一种锤击式钉枪，头部的长度l与锤击式钉枪的长度L的比值为1/6~1/4，头部的宽度w与锤击式钉枪的长度L的比值为1/2以上，头部的重量m与锤击式钉枪重量M的比值为1/2以上。
进一步地，手柄包括整体压铸而成的镁合金外壳。
进一步地，镁合金外壳厚度为不小于2mm，镁合金外壳的重量n为锤击式钉枪重量M的0.3以上。
进一步地，头部包括钉触发器，钉触发器上设有孔，钉触发器被设置为当触碰工件时，在反作用力的作用下，向锤击方向的反方向运动。
进一步地，头部包括钉击发组件，钉击发组件包括传动组件和击发片，击发片上设有孔。
进一步地，传动组件包括第一传动片和第二传动片，第一传动片的一端被设置为与镁合金外壳通过第一轴连接，第二传动片的一端被设置为与镁合金外壳通过第二轴连接，第一传动片的另一端被设置为与第二传动片的另一端通过第二轴相连。
进一步地，第一传动片的一端被设置为可穿过钉触发器上的孔，第二传动片的一端被设置为可穿过击发片上的孔。
进一步地，第一传动片被设置为在钉触发器的带动下运动，第二传动片被设置为与第一传动片运动的相反方向运动，击发片被设置为向第二传动片运动方向运动。

进一步地，手柄包括弹夹，弹夹被设置在镁合金外壳内部形成的空腔中。
与现有技术相比：本发明中，优化锤击式钉枪的尺寸和重量分配比例，在使用中，可以借助锤击式钉枪的自身重力将钉子打入工件中，减少了外力的使用，可以减轻手柄的震动。采用整体压铸成型的镁合金外壳，镁合金是以镁为原料的高性能轻型结构材料，比重与塑料相近；镁合金具有良好的阻尼系数和较高的阻尼容量，减振量大于铝合金和钢铁，当镁合金受外力作用时，应力分布更均匀，减震效果更好。

具体实施方式
以下结合附图和具体实施例进一步地说明本发明。
如图1所示，锤击式钉枪10包括头部2和手柄部1。手柄部1包括整体压铸而成的镁合金外壳5，头部2包括上盖6、前盖8和钉触发器9。上盖6与前盖8被设置为通过紧固件20连接，前盖8与镁合金外壳5被设置为通过紧固件30连接。上盖6和前盖8作为头部2的外壳，通过紧固连接方式包裹头部2。钉触发器9位于隔板3与前盖8之间，钉触发器9具有弯曲部92。在本实施例中，钉触发器9的弯曲部92被配置为撞击工件100。本实施例中，头部2的最前端是锤击式钉枪10的最前端，手柄1的最尾端是锤击式钉枪10的最尾端。
如图2-6所示，头部2包括钉击发组件4，钉击发组件4包括传动组件7、击发片50。传动组件7进一步包括第一传动片71和第二传动片72，第一传动片71的一端被设置为穿过钉触发器9的孔93，第二传动片72的一端被设置为穿过击发片50的孔501。第一传动片71与镁合金外壳5被设置为通过轴73枢转连接，第二传动片72与镁合金外壳5被设置为经轴74枢转连接，第一传动片71和第二传动片72被设置为由轴75枢转连接，轴73和轴74限定了轴75。在使用时，第一传动片71的运动带动第二传动片72的运动，第一传动片71和第二传动片72被设置为可以绕着轴75旋转或者枢转。镁合金外壳5上的孔52放置轴73，镁合金外壳5的孔53放置轴74。在本实施例中，第一传动片71穿过钉触发器9的孔93的部分和第二传动片72穿过击发片50的孔501的部分可以设置成圆形状，也可以考虑其他形状，如多边形或者类似形状。本实施例中，使用锤击式钉枪10所产生的震动会有一部分通过轴73和轴74传递到镁合金外壳5，从而减少震动所带来的手部的不适感。
弹性部件60设置在镁合金外壳5内，在本实施例中，弹性部件60可设为弹簧。弹性部件60的后端部被设置为邻接属于镁合金外壳5一部分的受压板51，弹性部件60的前端部被设置为邻接第二传动片72。在本实施例中，当锤击式钉枪10触碰工件100时，弹性部件60受到第二传动片72的作用，弹性部件60的前端部沿着锤击式钉枪10的长轴方向向弹性部件60的后端部运动。击发片50、隔板3和钉触发器9依次贴合，其中隔板3固定在镁合金外壳5上。隔板3总体上呈“L”型，隔板3所具有的底端部31用于容纳弹夹80的前端部81。在本实施例中，锤击式钉枪10的长轴是以头部2的最前端为起点，手柄1的最尾端为终点，起点至终点的方向为锤击式钉枪10的长轴方向，起点至终点的间距为锤击式钉枪10的长轴长度。
如图7-9所示，弹夹80被放置在镁合金外壳5形成的空腔54中。本实施例中，钉触发器9被设置为当触碰工件时，在反作用力的作用下，按箭头A所示方向移动。钉触发器9沿着箭头A方向推动第一传动片71穿过钉触发器9上孔93的部分，第一传动片71上的轴73会沿箭头B方向运动，轴75以与轴73相同方向运动，第二传动片72上的轴74沿箭头C方向运动，第二传动片72沿箭头D方向运动，弹性部件60的前端部受第二传动片72的带动沿箭头E方向变形压缩，第二传动片72同时带动击发片50沿箭头D方向运动，最后将钉90打入工件100内。在本实施例中，箭头A所示方向是锤击方向的相反方向，箭头B所示方向与箭头C所示方向相反，箭头D所示方向是锤击方向，箭头E所示方向是沿锤击式钉枪10长轴方向。
本实施例中，锤击式钉枪10的长度L为锤击式钉枪10的长轴的长度，从头部2的最前端沿锤击式钉枪10的长轴方向延伸，延伸的长度l为头部2的长度，头部2的长度l与锤击式钉枪10的长度L比值为1/6~1/4，将这部分定义为头部2。当锤击式钉枪10未使用时，从钉触发器9的弯曲部92的最底端至上盖6的上表面的距离，将这部分距离定义为头部2的宽度w，头部2的宽度w与锤击式钉枪10的长度L的比值为1/2以上，头部2的重量m与锤击式钉枪10的重量M的比值为1/2以上。镁合金外壳5的重量n与锤击式钉枪10的重量M的比值为0.3以上，镁合金外壳5的厚度为不小于2mm。优化锤击式钉枪的尺寸和重量分配比例，在使用中，可以借助锤击式钉枪的自身重力将钉子打入工件中，减少了外力的使用，可以减轻手柄的振动。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
