Abstract

本实用新型涉及一种膨胀螺栓套筒,包括:筒体,沿筒体底部壁面向上设置有长狭槽,长狭槽的略上方适当部位设有复数且向外具有倾斜角度的凸片。具有所述结构的本实用新型,其优点是可以使套筒更好卡掣于墙孔的孔壁中。

Description

改良的膨胀螺栓套筒
为在墙上固接工作物,人们通常使用套筒式膨胀螺栓,但当遇到结构强度较差的混凝土或砖墙时,由于孔壁结构的松软,而致膨胀螺栓无法仅仅通过套筒的变形有效卡掣于墙孔的孔壁中。
为此本申请人(设计人)曾在中国专利ZL96230268.6中提出了一种如图1所示的套筒设计,即在套筒10的外表面设置了长条凸体121,具有一定的过墙壁的卡掣效果。但由于长条体121系系于套筒10被冲孔所特别留置的不规则凸出体,其强度不佳,容易变形内陷,而致卡掣效果有限。
本实用新型的目的在于提供一种具有更佳墙孔卡掣效果的膨胀螺栓套筒。
本实用新型是这样实现的,膨胀螺栓套筒,包括:筒体,沿筒体底部壁面向上设置有长狭槽,长狭槽的略上方适当部位设有复数且向外具有倾斜角度的凸片。
具有所述结构的本实用新型,其优点是可以使套筒更好卡掣于墙孔的孔壁中。
以下附图和实施例将对本实用新型的结构特征作进一步说明:
图1是已有膨胀螺栓套筒的立体分解图。
图2是本实用新型的立体图。
图3是本实用新型与螺栓的立体分解图。
图4是本实用新型于壁孔向外迫张的动作图一。
实施例;
如图2所示,膨胀螺栓套筒,包括:筒体10,沿筒体10底部壁面向上设置有长狭槽12,长狭槽12的略上方适当部位设有复数且向外具有倾斜角度的凸片14。
使用本实用新型时,如图3、4所示,当对螺帽20旋转迫紧时,螺杆下方的锥形体24乃迫使套筒10向外变形扩张,即长狭槽12槽孔变大,倾斜凸片14强力卡掣于墙孔壁面W上。由于倾斜凸片14其下端系与筒体10结为—体,因此具有较高的受力强度,相对地对墙孔壁面的迫紧效果要比已有套筒为佳。
