Abstract

本实用新型一种双头膨胀螺栓，包括螺栓、螺套、膨胀块、锁紧螺帽，膨胀块二端设斜面，螺栓中间有一凹口，膨胀块放入凹口内，通过二端螺栓挤压，使膨胀块向外移动，使二个无附着物体之间相互固定，适用于建筑、机械、民用等方面使用。

Description

双头膨胀螺栓
技术领域
本实用新型涉及一种膨胀螺栓，尤其是指两个无附着物体之间相互固定的一种双头膨胀螺栓。
背景技术
目前公知的膨胀螺栓一方是以附着物体作固定(如水泥地、墙体等)，对二个无附着物体之间的固定起不了作用。
发明内容
本实用新型提供一种两物体之间用膨胀螺栓相互固定在一起，可拆卸又可重复使用的双头膨胀螺栓。
本实用新型解决其技术问题所采用的技术方案是：双头膨胀螺栓包括螺栓、螺套、锁紧螺帽、膨胀块四部分组成。螺套二头设置内螺纹，螺纹内径与螺栓外径相配合。螺套中间设一凹口，长度与膨胀块长度相吻合。膨胀块二端各设一斜面，螺丝往内拧动时，膨胀块斜面与螺栓一端接触，螺栓往内移动，膨胀块往外被顶出。当膨胀螺栓拧到位时，锁紧螺帽起锁紧(固定)螺栓作用。
本实用新型的有益效果是：通过两边螺栓向内旋转，挤压膨胀块向外移动，使二物体之间相互固定。
附图说明
图1是双头膨胀螺栓剖面图
图2是双头膨胀螺栓工作时的剖面图
图中1、螺栓；2、锁紧螺帽；3、螺套；4、膨胀块；5、钢管；6、固定体。
具体实施方式
下面结合附图对本实用新型作进一步说明
在图2中，螺套3的凹口内放入膨胀块4，固定体6卡入钢管5，螺套3二端螺纹口对准固定体6两边螺孔，螺栓1穿过固定体6螺孔向内旋入螺套3，膨胀块4被往外被挤出压住钢管5，固定体6与钢管5固定成功。拧紧锁紧螺帽2，固定完成。

Claims (2)

1.双头膨胀螺栓，它包括螺栓、螺套、膨胀块、锁紧螺帽，其特征是：螺套中间设一凹口，凹口长度与膨胀块长度吻合，膨胀块二端设一斜面。
2.根据权利要求1所述的双头膨胀螺栓，其特征是螺栓向内挤压膨胀块固定后，用锁紧螺帽锁定。
