一种防盗螺丝
本技术涉及机械零件
,具体为一种防盗螺丝。
技术介绍
螺丝是利用物体的斜面圆形旋转和摩擦力的物理学和数学原理,循序渐进地紧固器物机件的工具。螺丝是紧固件的通用说法,日常口头语。螺丝为日常生活中不可或缺的工业必需品:如照相机、眼镜、钟表、电子等使用的极小的螺丝;电视、电气制品、乐器、家具等的一般螺丝;至于工程、建筑、桥梁则使用大型螺丝、螺帽;交通器具、飞机、电车、汽车等则为大小螺丝并用。螺丝在工业上负有重要任务,只要地球上存在着工业,则螺丝的功能永远重要。螺丝是千百年来人们生产生活中的共同专利技术,按照应用领域来看,它是人类的第一大专利技术。目前很多的机械设备上都使用到了螺丝,现有螺丝结构包括螺杆和螺帽,螺帽外表面设有椭圆形口或十字口,当螺丝连接物件时,螺帽位于物件表面外侧,螺帽在物件表面会形成突起,用螺丝刀旋转螺丝,很容易就可以将螺丝取出,因此普通螺丝结构不具有安保的作用,因此设计了一种防盗螺丝。
技术实现思路
为实现上述目的,本技术提供如下技术方案:一种防盗螺丝,包括防盗螺丝帽与防盗螺丝杆,所述防盗螺丝帽与防盗螺丝杆为一体式结构,所述防盗螺丝杆上设置 ...
