Description

汽车用防水组合螺栓
技术领域
本实用新型涉及一种汽车用防水组合螺栓。
背景技术
传统组合螺栓,螺栓与垫片之间属于间隙配合,垫片容易脱落,而且起不到良好的防水作用。
发明内容
鉴于背景技术的不足,本实用新型所要解决的技术问题是提供一种能够防止垫片掉落且具有防水功能的汽车用防水组合螺栓。
为此,本实用新型是采用如下技术方案来实现的:
汽车用防水组合螺栓,包括螺杆和头部,所述螺杆上靠近头部位置套设有垫片,其特征是:所述垫片和螺杆过盈配合连接,所述螺杆上还套设有与垫片贴合的发泡棉,所述发泡棉位于垫片下方。
采用上述技术方案后,垫片和螺杆过盈配合连接,可有效防止垫片掉落,螺杆上还套设有与垫片贴合的发泡棉,使螺栓具备防水功能。
附图说明
本实用新型有如下附图:
图1为本实用新型的结构示意图。
具体实施方式
参照图所示,本实用新型提供的汽车用防水组合螺栓包括螺杆1和头部2,螺杆1上靠近头部2位置套设有垫片3,垫片3和螺杆1过盈配合连接,螺杆1上还套设有与垫片3贴合的发泡棉4,发泡棉4位于垫片3下方。
在本实施例中,垫片3和螺杆1过盈配合连接,通过外力将垫片压入螺杆1部,可有效防止垫片3掉落,螺杆1上还套设有与垫片3贴合的发泡棉4,使螺栓具备防水功能。
