Description

多功能紧固钉及其使用方法
技术领域
本发明涉及一种紧固钉，尤其涉及对紧固钉钉杆的螺纹结构进行改进以及紧固钉的使用方法。
背景技术
目前市场上制作使用的紧固螺丝钉主要有三类：多头螺丝（如图1所示）、拉爆螺丝（如图2所示）和顶爆螺丝（如图3所示）。上述三种广泛使用的紧固螺丝钉在坚硬的被紧固母体上固定物体一般没有问题，但是当被紧固母体不是坚硬材料，例如是沥青路面（也称柏油路面）时，现有技术的紧固螺丝钉就无法起到安全牢靠的稳固作用。以在沥青路面上固定减速胶板等交通设施为例，多头螺丝打入沥青路面后仍无法稳固；拉爆螺丝和顶爆螺丝的膨胀套胀开后，由于沥青路不够硬，因此也不能起到稳固作用。也就是说以上三种紧固螺丝钉均无法用于稳固沥青路面上的减速胶板等交通设施，本发明的紧固钉用于填补该技术的空白。
发明内容
（一）要解决的技术问题
本发明要解决的技术问题是：提供一种适合在非坚硬被紧固母体，如沥青路面上使用的多功能紧固钉及其使用方法。
（二）技术方案
为解决上述问题，本发明提供了一种多功能紧固钉，包括：螺帽、钉杆以及钉杆下端的钉杆尖端，所述钉杆周面分成三个实现不同功能的杆部区域，所述三个实现不同功能的杆部区域包括：位于钉杆上部的阻旋转直纹段，位于钉杆下部的旋紧螺纹段以及用于增强钉杆粘结力的至少一条环状胶水接纳凹槽；所述环状胶水接纳凹槽被设置在旋紧螺纹段中，并且与所述旋紧螺纹段的螺纹交叉。
所述胶水接纳凹槽有三条，最上面的一条位于所述阻旋转直纹段和旋紧螺纹段的交界处，该胶水接纳凹槽的底部略深于旋紧螺纹段的螺纹牙底以及阻旋转直纹段的齿纹底部，其余两条胶水接纳凹槽的底部略深于旋紧螺纹段的螺纹牙底。
所述阻旋转直纹段的长度与所述钉杆总长度的比小于三分之一，所述旋紧螺纹段的长度与所述钉杆总长度的比大于三分之二。
所述阻旋转直纹段的直径从上向下相同，所述旋紧螺纹段的直径从上向下逐渐减小。
所述螺帽与钉杆为一体结构。
又或者，所述螺帽与钉杆为可拆装的连接结构，所述钉杆的顶部直径较小且具有外螺纹，所述螺帽的底部设置有与该外螺纹旋配的螺孔。
所述螺帽的外形为六角形螺帽或其外形为圆形但其上面中部有内六角形凹位，或者所述螺帽上面中部设置有十字凹槽。
作为本发明的优选实施例，所述螺帽的顶部固定连接有一吊钩构成带吊钩的多功能紧固钉；或所述钉杆顶部直径较小的外螺纹加长，并且增加第二螺帽，构成固定天花板的多功能紧固钉。
本发明的技术方案还包括上述多功能紧固钉的使用方法，所述使用方法包括如下步骤：
步骤A：确定待安装物的安装位置，通过钻孔工具在被紧固母体上钻一小孔，该小孔的直径小于所述紧固钉的钉杆直径；
步骤B：将所述紧固钉的钉杆周面涂覆胶水；
步骤C：将所述紧固钉穿过待安装物上的安装孔后，打入步骤A所述预先钻好的被紧固母体的小孔内，滞留在胶水接纳凹槽内的胶水将被挤压扩散到所述旋紧螺纹段和阻旋转直纹段中，使所述紧固钉的钉杆表面与被紧固母体粘结在一起。
当所述紧固钉采用可拆装螺帽时，旋开所述紧固钉的螺帽后，可更换损坏或需要维修的被紧固件。
（三）有益效果
同现有技术相比较，本发明具有如下有益技术效果：钉杆具有阻旋转直纹段和旋紧螺纹段的特殊设计，并且旋转螺纹段上还设有用于增强螺钉粘结力的多条环状胶水接纳凹槽，从而本发明的紧固钉与被紧固母体之间不仅具有不同方向的螺纹啮合力，而且还具有较强的粘合力；因此本发明特别适合在非坚硬的被紧固母体上，如沥青路面上使用。另一方面，在紧固钉的钉杆和螺帽采用可拆装结构，能非常方便地更换损坏或需要维修的被固定物，减少工作量和维护成本。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明做进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参考图4至图6，本发明的多功能紧固钉包括螺帽1、钉杆2以及钉杆2下端的钉杆尖端3，所述钉杆2周面分成三个实现不同功能的杆部区域，所述三个实现不同功能的杆部区域包括：位于钉杆上部的阻旋转直纹段21，位于钉杆下部的旋紧螺纹段22以及用于增强钉杆粘结力的多条环状胶水接纳凹槽23；所述多条环状胶水接纳凹槽23被设置在旋紧螺纹段22中，并且与所述旋紧螺纹段22的螺纹交叉。本发明的紧固钉用于沥青路面减速胶板等交通设施的固定时，只需让钉杆周面沾上胶水后再打入路面，在打入紧固钉时，胶水接纳凹槽23内的胶水会向所述旋紧螺纹段22和阻旋转直纹段21扩散，从而可以扩大粘合面，增加钉杆与沥青路的粘合力，因此减速胶板可以被加强固定，不容易损毁。当然，本发明还可在其他被紧固母体上固定物体，例如固定天花、防盗网、座椅、门窗等，并不限于沥青路面上减速胶板的固定。
如图4至图6所示，所述胶水接纳凹槽23有三条，最上面的一条位于所述阻旋转直纹段21和旋紧螺纹段22的交界处，该胶水接纳凹槽23的底部略深于旋紧螺纹段22的螺纹牙底以及阻旋转直纹段21的齿纹底部，其余两条胶水接纳凹槽23的底部略深于旋紧螺纹段22的螺纹牙底，此设计有利于增加胶水的容纳空间，增加钉杆打入沥青路时彼此的粘合力。
如图4至图6所示，所述阻旋转直纹段21的长度与所述钉杆2总长度的比小于三分之一，所述旋紧螺纹段22的长度与所述钉杆2总长度的比大于三分之二，由此可以保证钉杆大部从减速胶板进入沥青路面内，少部分阻旋转直纹段21贴附在减速胶板上。具体实施过程中，钉杆长度可以具有多种型号，例如包括长型号和短型号。对于长型号紧固钉，所述阻旋转直纹段21的长度可以为25mm，各段旋紧螺纹段22的长度由所述螺帽1到所述钉杆尖端3方向依次可以为19mm、19mm、25mm。对于短型号紧固钉，所述阻旋转直纹段21的长度可以为20mm，各段旋紧螺纹段22的长度由所述螺帽1到所述钉杆尖端3方向依次可以为11.5mm、11.5mm、17mm。
所述阻旋转直纹段21的直径从上向下相同，所述旋紧螺纹段22的直径从上向下逐渐减小、也向下越变得尖细，从而可以增强钉杆与沥青路面的压紧，使其更容易钻入沥青路面等被紧固母体内，方便固定。
在具体实施过程中，优选地，可以将所述阻旋转直纹段21的直径设置为6.5mm，第一旋紧螺纹段22（靠近阻旋转直纹段21）的直径变化范围可以是7.0mm到6.9mm之间，第二旋紧螺纹段22的直径变化范围可以是6.9mm到6.8mm之间，第三旋紧螺纹段22（靠近所述钉杆尖端3）的直径其变化范围可以是6.8mm到5.4mm之间。
本发明的螺帽1和钉杆2具有一体装和可拆装两种设计。在图4和图5所示的实施例一中，所述螺帽1与钉杆2为一体结构，两者不可拆装。在图6所示的实施例二中，所述螺帽1与钉杆2为可拆装的连接结构，所述钉杆2的顶部直径较小且具有外螺纹，所述螺帽1的底部设置有与该外螺纹旋配的螺孔。
另外，本发明多功能紧固钉的螺帽1也可以具有多种形状设计，例如，所述螺帽1的外形可以为六角形或圆形，或为圆形但其上面中部有内六角形凹位。又或者，所述螺帽1上面中部设置有十字凹槽。本领域技术人员应当理解，本发明的螺帽1形状并不局限于此处所描述的若干设计，本发明完全可以根据实际需要，设计出更多实用性和鉴赏性强的螺帽1。
对本发明的多功能紧固钉进行适当变形，可以将其改造成为固定天花板的紧固钉或带吊钩的紧固钉。例如，在所述螺帽1的顶部固定连接一吊钩11，则构成带吊钩的多功能紧固钉，如图7所示。对于螺帽1和钉杆2可拆装的多功能紧固钉，把所述钉杆2顶部直径较小的外螺纹24加长，并且增加第二螺帽4，将构成可固定天花板的多功能紧固钉，如图8所示。
下面详细介绍本发明多功能紧固钉的使用方法，具体包括如下步骤：
步骤A：确定待安装物的安装位置，通过钻孔工具在被紧固母体上钻一小孔，该小孔的直径小于所述紧固钉的钉杆直径；
步骤B：将所述紧固钉的钉杆周面涂覆胶水；
步骤C：将所述紧固钉穿过待安装物上的安装孔后，打入步骤A所述预先钻好的被紧固母体的小孔内，滞留在胶水接纳凹槽23内的胶水将被挤压扩散到所述旋紧螺纹段22和阻旋转直纹段21中，使所述紧固钉的钉杆表面与被紧固母体粘结在一起。
当所述紧固钉采用可拆装螺帽1时，旋开所述紧固钉的螺帽1后，可更换损坏或需要维修的被紧固件。
工业实用性
本发明特别适合在非坚硬的被紧固母体上，如沥青路面上使用，能非常方便地更换损坏或需要维修的被固定物，减少工作量和维护成本。
