Description

一种特殊的膨胀螺栓
技术领域
本发明涉及混凝土建筑技术领域，尤其涉及一种特殊的膨胀螺栓。
背景技术
螺栓是由头部和螺杆两部分组成的紧固件，需要与螺母通过螺纹连接进行配合，用于紧固连接两个带有通孔的零件。在安装膨胀螺栓时，螺栓不易定位，易发生歪斜现象，存在安全隐患，且在拆卸时，膨胀套额螺栓无法取出，不利于施工位置的修复和二次施工。
因此，需要寻求一种新的技术来解决上述问题。
发明内容
本发明的目的是：提供一种特殊的膨胀螺栓。
为实现上述目的，本发明采用的技术方案是：
一种特殊的膨胀螺栓，包括螺栓头、螺杆、膨胀套，所述螺栓头下连接螺杆，所述螺杆的顶端外套接有膨胀套，所述螺杆与膨胀套之间通过螺纹连接，所述膨胀套外设有螺旋纹结构，所述螺杆外连接套筒，所述套筒与膨胀套可拆卸连接。
所述螺栓头内设有紧固装置。
所述紧固装置包括凹槽，所述凹槽中心设有圆柱，所述凹槽四周设有扭转孔。
在上述技术方案中，与现有技术相比，达到的有益效果是：螺杆由于膨胀套之间通过螺纹连接，便于拆卸和连接；套筒与膨胀套之间为可拆卸连接，便于套筒的拆卸，便于悬挂物件。
附图说明
附图1为本发明实施例一的结构示意图。
具体实施方式
下面结合附图及实施例对本发明作进一步描述。
实施例一：
如图1所述，本发明的一种特殊的膨胀螺栓，包括螺栓头1、螺杆2、膨胀套3，所述螺栓头1下连接螺杆2，所述螺杆2的顶端外套接有膨胀套3，所述螺杆2与膨胀套3之间通过螺纹4连接，所述膨胀套3外设有螺旋纹5结构，所述螺杆2外连接套筒6，所述套筒6与膨胀套3可拆卸连接。
所述螺栓头1内设有紧固装置。
所述紧固装置包括凹槽7，所述凹槽7中心设有圆柱8，所述凹槽7四周设有扭转孔9。
在上述技术方案中，与现有技术相比，达到的有益效果是：螺杆2由于膨胀套3之间通过螺纹4连接，便于拆卸和连接；套筒6与膨胀套3之间为可拆卸连接，便于套筒6的拆卸，便于悬挂物件。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
