Abstract

本实用新型涉及一种超级大螺栓,该螺栓包括螺杆和螺头,以及与之配套的螺母和垫圈,螺头与螺杆相连接,垫圈、螺母连接在螺杆上,在螺头上对称开有若干个螺孔,在每个螺孔中安装有内六角螺丝。采用本实用新型,在紧固或拆卸大螺栓时,只需要将若干个内六角螺丝逐步同时装上或卸下,就可以松开或紧固大螺栓,因此可以不受工具或空间限制,即方便,又能达到相应的机械强度。

Description

一种超级大螺栓
技术领域
[0001] 本实用新型涉及一种超级大螺栓。
背景技术
[0002]目前,在机械行业中,螺栓的使用是最频繁的,但在机械强度大的部位,螺栓的选用具有一定局限性,一是要求选用抗拉抗剪强度大的螺栓,二是需要选用剪切面大的螺栓,然而大螺栓在使用上却非常不方便,有时缺少相应的紧固或拆卸大型扳手,有时又因为在有限的空间使用,导致有配套扳手也难以发挥作用。
发明内容
[0003] 本实用新型的目的是提供使用普通规格扳手,即使在有限空间情况下就能紧固或拆卸的一种超级大螺栓。
[0004] 本实用新型采取的技术方案是:一种超级大螺栓,包括螺杆和螺头,以及与之配套的螺母和垫圈,螺头与螺杆相连接,垫圈、螺母连接在螺杆上,其特征在于在螺头上对称开有若干个螺孔,在每个螺孔中安装有内六角螺丝。
[0005] 采用本实用新型,在紧固或拆卸大螺栓时,只需要将若干个内六角螺丝逐步同时装上或卸下,就可以松开或紧固大螺栓,因此可以不受工具或空间限制,即方便,又能达到相应的机械强度。
附图说明
[0006] 图1是本实用新型的剖示示意图。
[0007] 图2是本实用新型的螺头平面示意图。
[0008] 图中序号表示:螺头1、内六角螺丝2、螺杆3、垫圈4、螺母5、螺孔6。
具体实施方式
[0009] 下面结合具体的实施例对实用新型作进一步说明。
[0010] 参照图1和图2,该超级大螺栓包括螺杆3和螺头1,以及与之配套的螺母5和垫圈4,螺头I与螺杆3相连接,垫圈4、螺母5连接在螺杆3上,在螺头上对称开有若干个螺孔6,在每个螺孔6中安装有内六角螺丝2。使用时,只要将六个内六角螺丝2分别安装在六个螺孔6中,顶住垫圈4及螺母5,逐个逐步旋紧内六角螺丝2,把紧固力分散分成六个点来注力,螺杆3也会逐步紧固,这样也可达到同样效果。反之,如需要拆卸时,只需要轻松拆卸下六个内六角螺丝2即可。
