Abstract

本实用新型涉及紧固件，特别是一种具有排屑槽的螺旋紧固件，比如螺钉或螺栓，由尾端和螺旋段(1)构成，呈锥形或圆柱形，其特征在于螺旋段(1)的前段制有轴向凹槽(2)，凹槽(2)可制成三角槽。本实用新型可将螺钉或螺栓在攻入物件时所产生的屑物被刮离到螺旋段的前段的凹槽内，避免了屑物阻塞螺纹之间的空隙，使螺钉或螺栓在使用时阻力小，承受的扭力减少，尾端与工具之间不易打滑，从而可保证螺钉或螺栓的正常锁固作用。

Description

具有排屑槽的螺旋紧固件
技术领域：
本实用新型涉及紧固件，特别是一种具有排屑槽的螺旋紧固件，比如螺钉或螺栓。
背景技术：
现有的螺旋紧固件，包括螺杆、螺栓，由尾端和螺旋段组成，尾端为施力端，螺旋段为进入物体段，呈锥形或圆柱形。当螺旋段攻入物件时会产生一些木屑或铁屑，容易填塞螺纹之间的空隙，越往深处旋入，所需扭力越大，经常会导致尾端损坏而与工具之间打滑，甚至无法再继续深入，不能实现正常锁固作用，进而对今后若需退出造成困难。
发明内容：
本实用新型的目的是提供一种将攻入物件所产生的屑物刮离的具有排屑槽的螺旋紧固件。
本实用新型一种具有排屑槽的螺旋紧固件，由尾端和螺旋段组成，呈锥形或圆柱形，其特征在于螺旋段的前段制有轴向凹槽。
上述凹槽为三角槽。
螺栓的螺旋段的前端制成缩径的导向头。
本实用新型的优点在于，螺钉或螺栓在攻入物件时所产生的屑物被刮离到螺旋段的前段的凹槽内，避免了屑物阻塞螺纹之间的空隙，使螺钉或螺栓在使用时阻力小，承受的扭力减少，尾端与工具之间不易打滑，从而可保证螺钉或螺栓的正常锁固作用。
附图说明：
图1为本实用新型实施例主视图。
图2为图1中A-A截面图。
具体实施方式：
下面结合附图，详细说明本实用新型的实施例，
本实施例为一种螺栓紧固件，呈圆柱形，特别适用于与被紧固物上的内螺纹盲孔螺纹配合，比如接地螺钉，其由尾端和螺旋段1组成，螺旋段的前段制有轴向三角凹槽2，该三角凹槽2可将攻入物件时刮离下来的屑物收集在内；螺栓的前端制成缩径的导向头3，以利使用时螺栓的前端可方便进入内螺纹孔。
