Abstract

本发明公开了一种螺丝钉，包括一端大一端小的圆台型的钉体，所述钉体的径向一周设有螺纹段，所述钉体的小端设有倾斜的尖头，所述钉体的大端设有钉盖，所述钉体包括两段或两段以上通过相互嵌装的球型凸起和球型凹座相连接的钉体段，当所述顶盖旋转时，两段所述钉体段之间相互球面旋转，两段所述钉体段的前进方向不同。本发明与现有技术相比，可以解决现有的螺丝钉紧固力不够，容易松动的问题。

Description

螺丝钉
技术领域
本发明涉及五金件制造技术领域，尤其是一种带螺纹的一端尖的紧固件。
背景技术
现有的螺丝钉一般包括一端大一端小的圆台型的钉体，在钉体的径向一周设有螺纹段，钉体的小端设有倾斜的尖头，钉体的大端设有钉盖，一般使用在相对于螺丝钉软的材料上，通过自身的旋转钻进待钉物件中，在钻进时，螺纹起到旋转切割的作用，使螺丝钉前行钻入，但是在螺纹切割待钉物件时容易形成空隙，在收到长时间摇动的情况下，螺丝钉在轴线方向上紧固力不够，容易松动，存在安全隐患。
发明内容
本发明所要解决的问题是提供一种螺丝钉，以解决现有的螺丝钉紧固力不够，容易松动的问题。
为了解决上述问题，本发明的技术方案是：本螺丝钉包括一端大一端小的圆台型的钉体，所述钉体的径向一周设有螺纹段，所述钉体的小端设有倾斜的尖头，所述钉体的大端设有钉盖，所述钉体包括两段或两段以上通过相互嵌装的球型凸起和球型凹座相连接的钉体段，当所述顶盖旋转时，两段所述钉体段之间相互球面旋转，两段所述钉体段的前进方向不同。
上述技术方案中，更为具体的方案可以是：所述钉体段有两段，所述球型凸起安装在连接所述顶盖的所述钉体段上，所述球型凹座安装在带有所述尖头的所述钉体段上。
进一步的：所述球型凸起和与之相连接的所述钉体段一体成型，所述球型凹座和与之相连接的所述钉体段一体成型。
由于采用了上述技术方案，本发明与现有技术相比具有如下有益效果：
本螺丝钉采用相互嵌装的球型凸起和球型凹座将传统的钉体分成两段或至少两段的钉体段，当顶盖旋转时，两段钉体段之间相互球面旋转，两段钉体段的前进方向不同，再配合非直线的螺丝钉带上的导钉件，使钉体在钻进待钉物件时可以形成非直线的夹角，夹角本身形成较大的紧固力，防止钉体回锁松动，较之传统直线型的钉体，有较大的紧固力，而且相互嵌装的球型凸起和球型凹座可以任意调节夹角方向和夹角角度，一个待钉物件上多个不同夹角和方向的螺丝钉预紧，可以具有非常好的紧固力，并且使用方便。
附图说明
图1是本发明实施例的主视图。
具体实施方式
下面结合附图对本发明实施例作进一步详述：
如图1所示的本螺丝钉，它包括一端大一端小的圆台型的钉体，钉体的径向一周设有螺纹段3，钉体的小端设有倾斜的尖头6-1，钉体的大端设有钉盖1，钉体包括两段或两段以上通过相互嵌装的球型凸起4和球型凹座5相连接的钉体段，钉体段有两段，球型凸起4安装在连接顶盖1的钉体段2上，球型凹座5安装在带有尖头6-1的钉体段6上。当顶盖1旋转时，两段钉体段之间相互球面旋转，两段钉体段的前进方向不同，再配合非直线的螺丝钉带上的导钉件，使钉体在钻进待钉物件时可以形成非直线的夹角，夹角本身形成较大的紧固力，防止钉体回锁松动，较之传统直线型的钉体，有较大的紧固力，而且相互嵌装的球型凸起4和球型凹座5可以任意调节夹角方向和夹角角度，一个待钉物件上多个不同夹角和方向的螺丝钉预紧，可以具有非常好的紧固力，并且使用方便。球型凸起4和与之相连接的钉体段2一体成型，球型凹座5和与之相连接的钉体段6一体成型，这样可以使两段钉体段的连接稳定性高，工作可靠。
