Abstract

本实用新型涉及一种防盗螺钉,主要用于汽车和自行车牌照的防盗,其特征在于圆顶螺头上的“一”字形槽两侧有两个交错排列的弧面凹陷,弧面上部与螺头形成尖凸台,下边与“一”字形槽的槽底相平,该螺钉可有效的防止车牌的被盗,具有结构简单、新颖、成本低的优点。

Description

一种防盗螺钉
(一)技术领域
本实用新型涉及一种防盗螺钉,用于汽车和自行车牌照的防盗,属于五金工具。
(二)背景技术
汽车和自行车的牌照常常被盗,主要是牌照的固定螺钉可以拆卸,有一种防盗螺钉,它在固定车牌后再用力拧断螺头,这样可以防止偷盗者拆卸螺钉,但这种螺钉结构复杂、成本高,而且需大力气拧断,还会在拧断螺钉的断面留有金属毛刺,很易伤人刮物,同时也不美观。
(三)发明内容
本实用新型的任务正是为了克服上述已有技术存在的缺点与不足而设计一种结构简单、新颖、美观的防盗螺钉,从而可有效的防止车牌的被盗。
本实用新型的任务是这样实现的:
防盗螺钉,它由螺杆(3)和螺头(1)组成,其特征在于圆顶螺头上的“一”字形槽(4)两侧有两个交错排列的弧面凹陷(2),弧面上部与螺头形成尖凸台(5)下边与“一”字形槽的槽底相平。
由于采取上述技术方案使本实用新型与已有技术相比具有结构简单、新颖、美观,防盗效果好成本低的优点及效果。
(四)附图说明
图1为本实用新型结构示意图
图2为图1的俯视图
(五)具体实施方式
本实用新型的防盗螺钉,由图1图2所示,它由螺杆(3)和螺头(1)组成,在圆顶螺头上的“一”字形槽(4)两侧有两个交错排列的弧面凹陷(2)弧面上部与凹槽两侧的圆顶形成尖凸台(5)下部与“一”字形槽的槽底相平,当使用时,用改锥头插入“一”字形凹槽,顺时针旋转改锥头在两尖凸头阻挡下即将车牌拧紧固定,当反时针旋转改锥时由于圆弧凹陷底部与“一”字槽底相平,而无阻挡改锥头而顺着圆弧凹陷滑动无法用力拧动螺钉,车牌即无法拆卸,因此可防止偷盗者盗窃车牌。
