Description

一种紧固螺栓 技术领域
本发明涉及螺栓领域，特别是涉及一种紧固螺栓。
背景技术
现有的紧固螺栓都是通过螺母从螺杆上旋上或旋下，来安装和拆卸零部件，这种连接方式，螺母处必须预留较大的空间，来旋转螺母，特别是当连接操作力较大时，还需要通过使用扳手等工具才能将螺母从螺杆上旋上或旋下，操作空间需求较大，并且现有的螺栓，一个螺杆只能与一种规格的螺母相配合使用，实际使用中具有一定的局限性。
发明内容
本发明主要解决的技术问题是提供一种占用空间小、操作方便、操作空间灵活、应用范围广、使用效果好的紧固螺栓。
为解决上述技术问题，本发明提供一种紧固螺栓，包括：头部、螺杆、第一螺母和第二螺母，所述螺杆上设有双线外螺纹，所述双线外螺纹分别为第一外螺纹和第二外螺纹，所述第一外螺纹与所述第二外螺纹相间隔交叉，所述螺杆的上部与头部固定连接，所述第一螺母设有与所述第一外螺纹相配合的第一内螺纹，所述第二螺母设有与所述第二外螺纹相配合的第二内螺纹。
在本发明一个较佳实施例中，所述头部设置成中空球体，所述头部中心处设有一个第一通孔。
在本发明一个较佳实施例中，所述头部还设有一个与第一通孔相垂直的第二通孔。
在本发明一个较佳实施例中，所述第一通孔的直径大于所述第二通孔的直径。
在本发明一个较佳实施例中，所述第一外螺纹的螺距小于所述第二外螺纹的螺距。
本发明的有益效果是：本发明紧固螺栓具有双线外螺纹，能够与不同规格的螺母相配合使用，头部的两个通孔能够用来拧开和拧上螺母，占用空间小，操作方便，操作空间灵活，应用范围广，使用效果好。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1是本发明的紧固螺栓一较佳实施例的结构示意图；
附图中各部件的标记如下：1、头部；11、第一通孔；12、第二通孔；2、
螺杆；21、第一外螺纹；22、第二外螺纹；3、第一螺母；4、第二螺母。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1，本发明实施例包括：
一种紧固螺栓，包括：头部1、螺杆2、第一螺母3和第二螺母4，所述螺杆2上设有双线外螺纹，所述双线外螺纹分别为第一外螺纹21和第二外螺纹22， 所述第一外螺纹21与所述第二外螺纹22相间隔交叉，所述螺杆2的上部与头部1固定连接，所述第一螺母3设有与所述第一外螺纹21相配合的第一内螺纹，所述第二螺母4设有与所述第二外螺纹22相配合的第二内螺纹。
由于螺杆2上设有的是双线螺纹，这种螺杆2可以与两种螺母相配合使用，使用范围更广泛，使用效果更好。
另外，所述头部1设置成中空球体，所述头部1中心处设有一个第一通孔11。通过第一通孔11可以使用一根相匹配的直杆从螺栓的底部旋上或旋下螺母，占用空间较小。
另外，所述头部1还设有一个与第一通孔11相垂直的第二通孔12。同样的，通过第二通孔12同样可以使用一根相匹配的直杆从螺栓的底部旋上或旋下螺母，占用空间较小，而不必像现有螺栓那样必须从螺母上操作才能将螺栓紧固，操作空间灵活。
另外，所述第一通孔11的直径大于所述第二通孔12的直径。
另外，所述第一外螺纹21的螺距小于所述第二外螺纹22的螺距。
区别于现有技术，本发明紧固螺栓具有双线外螺纹，能够与不同规格的螺母相配合使用，头部的两个通孔能够用来拧开和拧上螺母，占用空间小，操作方便，操作空间灵活，应用范围广，使用效果好。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
