Abstract

本实用新型提供了一种膨胀螺栓,其特征在于:在栓体1的端部,靠近螺纹杆12的一端设有开口槽13和膨胀片14;螺母2为锥形,在螺母2的边部设有尖端21;其有益效果为:安装使用方便,易于拆卸。

Description

一种膨胀螺栓
技术领域
本实用新型涉及一种连接装置,尤其涉及一种膨胀螺栓。
背景技术
现有的膨胀螺栓包括一根螺杆,螺杆的外面设有膨胀管,螺杆的底部呈锥形,顶部设有螺丝和螺母,其膨胀是通过旋转套设于螺杆上的螺母来提起螺杆,再由螺杆底部顶开膨胀片,达到安装连接的目的;但是,这种膨胀螺栓使用过程中其螺杆头部裸露在外面,易腐蚀生锈难于拆卸。
发明内容
本实用新型的目的:提供一种新型的膨胀螺栓,可避免螺杆过长裸露在外面,且安装使用方便,易于拆卸。
本实用新型的技术方案在于:提供了一种新型的膨胀螺栓,由栓体1和螺母2组成,所述栓体1的一端设有螺钉11,另一端设有螺纹杆12,所述螺纹杆直径小于栓体1的直径,在栓体1的端部,靠近螺纹杆12的一端设有开口槽13和膨胀片14;所述螺母2为锥形,边部设有尖端21。
本实用新型的有益效果:本实用新型膨胀螺栓在安装使用时拧动螺钉,螺钉既不会向外部延伸,也不会向内层延伸,而是通过螺纹杆部移动锥形螺母实现安装过程,膨胀螺栓螺纹连接件头部与墙面或地面等外部安装面平齐,结构简单,安装使用方便,避免腐蚀。
附图说明
图1是本实用新型膨胀螺栓结构示意图。
图2是本实用新型膨胀螺栓使用状态示意图。
具体实施方式
现通过实施例并结合附图对本实用新型作进一步说明,如图1所示,是本实用新型膨胀螺栓结构示意图,其中1是栓体、2是螺母、11是螺钉、12是螺纹杆、13是开口槽、14是膨胀片、21是尖端;膨胀螺栓由栓体1和螺母2组成,所述栓体1的一端设有螺钉11,另一端设有螺纹杆12,所述螺纹杆直径小于栓体1的直径,在栓体1的端部,靠近螺纹杆12的一端设有开口槽13和膨胀片14;所述螺母2为锥形,边部设有尖端21。
图2是本实用新型膨胀螺栓使用状态示意图,使用时通过螺钉头部拧动螺钉11,即可将圆锥形螺母2挤入栓体1内,圆锥形螺母2将栓体1一端的膨胀片14向外侧张开,从而实现安装过程。
以上所述仅为本实用新型的较佳实施例,并非用以限定本实用新型的申请范围;凡其他未脱离本实用新型所揭示的实质下所完成的等效改变或修饰,均应包含在下述的权利要求书范围内。
