Abstract

一种防打滑膨胀螺栓,由螺栓、套筒组成,其特征在于:螺栓尾部(1)两侧制有一对翅状形凸块(2),在套筒(3)上方与凸块对应位置制有槽口(4)。本实用新型解决了现有的膨胀螺栓易打滑现象,影响施工进度,劳动强度大之不足。具有防打滑效果显著、不增加生产成本、生产工艺简单,保障施工顺利进行,减轻施工者劳动强度诸多优点。

Description

防打滑膨胀螺栓
技术领域
本实用新型涉及建筑紧固件领域,更确切地说是一种利用物理劈的原理来防止现有的膨胀螺栓打滑的螺栓。
背景技术
膨胀螺栓在建筑上使用较广泛,在普通家庭,安装吊扇、吊灯、空调、热水器处处有它的身影,但现有的膨胀螺栓,是单纯依靠螺母的拉力,使螺栓尾的锥面将套管胀开来实现的,因此,常出现打滑现象,膨胀螺栓安装的位置,都在天花板、墙壁高处、以至室外高处,一旦出现打滑现象,要将螺栓取出极非易事,影响施工进度,劳动强度大,在室外高处还会引发事故。虽然目前已有防滑膨胀螺栓的专利出现,但以结构复杂或价格贵至今无人问津。
发明内容
本实用新型目的在于克服上述之不足,提供一种不会打滑、不增加生产成本、生产工艺简单的防打滑膨胀螺栓。
本实用新型的目的是采用以下技术来实现的:一种防打滑膨胀螺栓,由螺栓、套筒组成,其特征在于:在螺栓尾部两侧各制有一对翅状形凸块,在套筒上方与凸块对应位置制有槽口,当螺栓在螺母的拉力下,凸块嵌入槽中,防止打滑,螺栓下方按现有技术,制有螺纹、装有垫圈及螺母。
本实用新型的显著效果:防打滑效果显著、不增加生产成本、生产工艺简单,保障施工顺利进行,减轻施工者劳动强度。
附图说明
附图为本实用新型的结构示意图。以下结合附图对本实用新型作进一步阐述。
具体实施方式
参见图,螺栓尾部1两侧制有一对翅状形凸块2,在套筒3上方与凸块对应位置制有槽口4,螺栓下端按现有技术,制有螺纹5、装有垫圈6及螺母7。

Claims (2)
