Abstract

本实用新型是一种双端膨胀螺栓,由现有的一端具有圆锥面的螺杆,套在螺杆上且与圆锥面相配合的带有膨胀瓣的膨胀套,与螺杆连接的螺母,其特点是:在膨胀套的另一端也设置膨胀瓣,并设置与膨胀瓣相配合的带圆锥面的楔套组成。具有双端膨胀、固定牢固、承载能力强等优点。

Description

双端膨胀螺栓
一种双端膨胀螺栓。属于紧固件。
现有的膨胀螺栓为一端膨胀结构，承载能力差。
本实用新型的目的在于提供一种固定牢固、承载能力强的双端膨胀螺栓。
本实用新型的目的是由附图给出的实施例的技术方案来实现的。图1为本实用新型双端膨胀螺栓的结构示意图。双端膨胀螺栓，由底部带有圆锥面(1)的螺杆(2)，套于螺杆(2)上且与螺杆(2)底部的圆锥面(1)相配合的、带有膨胀瓣(7)的膨胀套(3)，与螺杆(2)连接的螺母(5)，其特殊之处在于：在膨胀套(3)的另一端设置膨胀瓣(6)，并设置与膨胀瓣(6)相配合的带圆锥面的楔套(4)组成。
本实用新型的双端膨胀螺栓与现有的一端膨胀螺栓相比，由于本实用新型在螺杆的两端都设有膨胀瓣，使膨胀螺栓在两个圆周面上膨胀。具有固定牢固、承载能力强等优点。
