Abstract

本实用新型涉及与胀套结合成整件紧固于壁或类似件内的其它器件的技术,这种内膨胀自锁螺栓,包括螺帽(3)拧在螺帽(3)上的内胀套(1)、插在内胀套(1)上段的内胀钉(2)。该螺栓节省原材料,固定牢固,安装方便快捷。

Description

内膨胀自锁螺栓
本实用新型属于与胀套结合成整件紧固于壁或类似件内的其它器件的技术领域。
现在我们用的膨胀螺栓,包括内胀套、内螺栓和沉头,体积大,成本高,而且要固定在墙壁或其它物件上时要钻的孔比膨胀螺栓自身的直径大的多,因此它耗费的原材料多,成本高,且固定不牢固,而且内螺栓容易在拧过力后从胀套中拔出。
本实用新型的目的是提供一种体积小,节省原材料,固定牢固,且内胀钉不脱出的膨胀螺栓。
这种内膨胀自锁螺栓,包括螺帽,与螺帽结合的内胀套,插在内胀套内的内胀钉。
由于该膨胀螺栓只有螺帽、内胀套和内胀钉,因此体积小,节省原材料,且加工容易,成本低,只要将内胀钉用锤子砸入内胀套的内部,内胀套既最大限度的张开,固定牢固,而内胀钉是向里去,而非向外拉,因此内胀钉不可能从内胀套中脱出。
附图示出了本实用新型的实施例,其中:
图1所示为内膨胀自锁螺栓的正视图;
图2所示为沿图1所示A-A线的剖视图;
图3所示为沿图1所示B-B线的剖视图。
如图所示的内膨胀自锁螺栓,包括内胀套1,内胀套1呈管状、下段壁上设有缺口,且下段壁上设有均匀分布的四个缺口。套在内胀套1上的平垫5,紧挨平垫5套在内胀套1上的弹簧垫4,拧在内胀套1上的螺母3,从上端插入内胀套(1)中的内胀钉(2)。
在使用时,在墙壁、地面或其它物件上打上相应尺寸的孔,将螺栓插入孔中,用锤子将内胀钉打入,即将该螺栓固定在孔中,既快捷、方便,又不会象现在用的膨胀螺栓那样有时将内螺栓拔出。既节省材料,又使得施工快、方便。且固定牢固。
