Abstract

一种防盗螺栓,包括九角螺帽,柱状凸台和螺杆,所述九角螺帽是在圆柱体上均匀冲出九道凹槽,形成带有九个棱角的柱体,柱状凸台的上部连接九角螺帽,下部连接螺杆,所述螺杆呈圆柱体,且柱体表面上设有螺纹。本实用新型的有益效果为:防盗螺栓带有九角螺帽,九角螺帽带有九个大小相等的棱角,与普通的螺帽相比,九角螺帽不容易被普通的扳手松开,从而达到防盗的效果,防盗螺栓紧固的部件也更安全。

Description

一种防盗螺栓
技术领域
本实用新型涉及一种紧固装置,尤其涉及一种防盗螺栓。
背景技术
目前输电、邮电、铁塔、桥梁、公路、铁路护栏以及一些无人看管的野外工程设施都离不开各式各样的紧固装置,而现在的大多数紧固件装置包括螺栓仅由于设计单一,很容易松动,这就给很多不法之徒留下可乘之机。如专利号为02262747.2的实用新型专利,公开了一种连接螺栓,该螺栓包括螺杆和螺帽,其特征是螺杆为两端直径小于中部直径的双锥形双头螺杆,螺杆的两头分别套接膨胀内锥套,且与螺帽相连接,膨胀内锥套为有一断口的不封闭圆锥套,断口为斜剖口或直剖口。本实用新型克服了普通连接螺栓在过盈配合状态下的装卸极为繁琐和困难,不仅劳动强度大,而且还易损伤螺杆螺纹的缺陷,且有结构简单,装卸方便,连接可靠的优点。但是该螺栓存在的问题是不法分子使用一把扳手、老虎钳或其他简单工具就可以将螺栓松开,实施盗窃。再比如专利号为02143674.6的实用新型专利,公开一种防松的螺栓,它是由螺纹处开有凹槽的螺栓;下端设有棘轮卡套,顶部设有与开有凹槽的螺栓相对应的开口的防松动卡套;上紧固螺母;下紧固螺母及弹簧垫圈组成。螺栓安在工件上,套上弹簧垫圈,拧上下紧固螺母,套上防松动卡套再拧上紧固螺母,下紧固螺母在防松动卡套的棘轮卡套及凸齿的约束下就不能左右转动,则达到防松动的目的。本实用新型简单实用安全有效,但是存在同样的可以用普通工具将其打开的缺陷。这样的偷盗行为不仅给国家带来的是不可估量的经济损失,更多的时候会给公共安全带来巨大的威胁,比如不法分子为了从铁路上偷盗一点钢铁,往往会导致火车出轨,导致大量人员伤亡,因此对于输电、邮电、铁塔、桥梁、公路、铁路护栏以及一些无人看管的野外工程设施都应该采取特设的紧固装置,让不法分子用普通的工具无法达到偷盗的目的,这样不仅减少了经济上的损失,还可以防止危险后果的发生。
实用新型内容
本实用新型的目的是提供一种防盗螺栓,以克服普通螺栓很容易被松开、被偷盗的不足。一种防盗螺栓是通过以下技术方案实现的:一种防盗螺栓,包括九角螺帽、柱状凸台和螺杆,所述九角螺帽的侧面均匀分布九道棱角,所述柱状凸台的上部连接九角螺帽,下部连接螺杆,螺杆上设有螺纹;且所述柱状凸台的底面积大于九角螺帽的底面积,九角螺帽的底面积大于螺杆的底面积。其中九角螺帽带有九个大小相等的棱角。
本实用新型的有益效果为:带有九角螺帽的防盗螺栓的紧固效果更加突出,不易被普通工具旋开,带来更加安全的紧固效果。
附图说明
图1是本实用新型所述的一种防盗螺栓的主视图;
图2是本实用新型所述的一种防盗螺栓的俯视图。
具体实施方式
下面根据附图对本实用新型作详细说明,但不作为对实用新型的进一步限定。一种防盗螺栓,包括九角螺帽1,柱状凸台2和螺杆3,所述柱状凸台2的上部连接九角螺帽1,九角螺帽1的侧面带有分布均匀的九个棱角4,所述柱状凸台2的下部连接螺杆3,螺杆3上带有螺纹5。

Claims (3)

1.一种防盗螺栓,包括柱状凸台和螺杆,其特征在于:所述防盗螺栓还包括九角螺帽,所述九角螺帽带有九个大小相等的棱角,其下部连接柱状凸台,所述柱状凸台的下部连接螺杆。
2.根据权利要求1所述的一种防盗螺栓,其特征在于:螺杆上设有螺纹。
3.根据权利要求1所述的一种防盗螺栓,其特征在于:所述柱状凸台的底面积大于九角螺帽的底面积,九角螺帽的底面积大于螺杆的底面积。
