Description

一种膨胀螺栓
技术领域
本发明涉及一种五金配件技术领域,具体为一种膨胀螺栓。
背景技术
现阶段,人们在装修房屋、安装水电的时候都会用到膨胀螺栓,膨胀螺栓结构简单,使用方便,但是现阶段的膨胀螺栓的膨胀套采用单一的塑料或者单一的金属制成,没有加强结构,这就使得膨胀螺栓的膨胀套在使用时,容易损坏,且现阶段的普通膨胀螺栓采用单一的旋紧式膨胀紧固的方法,单一的紧固结构容易造成安装东西不牢固的现象,且一旦紧固之后很难再次拆卸,给使用者造成极大的不便,为此,我们提出一种膨胀螺栓。
发明内容
针对上述存在的技术问题,本发明的目的是:提出了一种结实耐用的膨胀螺栓。
本发明的技术解决方案是这样实现的:一种膨胀螺栓,包括螺栓一、膨胀套和螺栓二,所述螺栓一的表面右侧套接有螺母,所述螺栓一的右端面设有十字形槽一,所述螺栓一的表面设有外螺纹一,所述膨胀套的内腔表面设有内螺纹一,所述膨胀套通过内螺纹一和外螺纹一套接在螺栓一的表面,所述膨胀套的内腔设有加强线一和加强线二,所述螺栓一的内腔表面设有内螺纹二,所述螺栓二的表面设有外螺纹二,所述螺栓二通过外螺纹二和内螺纹二套接在螺栓一的内腔,所述螺栓二的右端面设有十字形槽二,所述螺栓二的左端面上下部分别活动设有连接杆一和连接杆二,所述连接杆一和连接杆二的左端分别设有固定卡一和固定卡二,所述固定卡一和固定卡二之间设有弹簧。
优选的,所述加强线一和加强线二在膨胀套的内腔均匀分布,且所述加强线一和加强线二交错排列形成网状。
优选的,所述固定卡一和固定卡二均呈锥形。
优选的,所述螺母和膨胀套之间设有橡胶垫。
优选的,所述膨胀套的表面均匀设有凹槽。
由于上述技术方案的运用,本发明与现有技术相比具有下列优点:
本发明的膨胀螺栓,膨胀套的内腔设有加强线一和加强线二,该结构增加了膨胀套的强度,使膨胀套结实耐用,膨胀套通过内外螺纹套接在螺栓一的内腔,该结构使膨胀螺栓结构紧密,使用起来不易松懈,螺栓一的内腔套接有螺栓二,螺栓二的左端活动设有连接杆,连接杆侧面设有固定卡,该结构可以在膨胀螺栓外部紧固的同时内部再次卡紧,采用双层卡紧结构,使膨胀螺栓安装东西更加紧固,且可以通过反向旋转螺栓二使固定卡收缩,从而便于拆卸已经安装的东西,该膨胀螺栓,结构简单,采用双层卡紧结构,固定东西比较牢固,且膨胀套采用加强结构,使膨胀套比较耐用。
附图说明
下面结合附图对本发明技术方案作进一步说明:
图1为本发明结构示意图;
图2为本发明的螺栓一和螺栓二安装结构的右视图;
图3为膨胀套的截面图。
图中:1、螺栓一;11、外螺纹一;12、内螺纹二;13、十字形槽一;2、膨胀套;21、内螺纹一;22、凹槽;23、加强线一;24、加强线二;3、螺栓二;31、外螺纹二;32、十字形槽二;、4、连接杆一;5、连接杆二;6、固定卡一;7、固定卡二;8、弹簧;9、螺母;10、橡胶垫。
具体实施方式
下面结合附图来说明本发明。
如图1-3所示,本发明提供的一种膨胀螺栓,包括螺栓一1、膨胀套2和螺栓二3,螺栓一1的表面右侧套接有螺母9,螺母9和膨胀套2之间设有橡胶垫10,橡胶垫10可以保护膨胀套2,螺栓一1的右端面设有十字形槽一13,十字形槽一13使螺栓一1使用起来方便,螺栓一1的表面设有外螺纹一11,膨胀套2的表面均匀设有凹槽22,膨胀套2的内腔表面设有内螺纹一21,膨胀套2通过内螺纹一21和外螺纹一11套接在螺栓一1的表面,膨胀套2的内腔设有加强线一23和加强线二24,加强线一23和加强线二24在膨胀套2的内腔均匀分布,且加强线一23和加强线二24交错排列形成网状,该结构增加了膨胀套2的强度,使膨胀套2结实耐用,螺栓一1的内腔表面设有内螺纹二12,所述螺栓二3的表面设有外螺纹二31,螺栓二3通过外螺纹二31和内螺纹二12套接在螺栓一1的内腔,螺栓二3的右端面设有十字形槽二32,螺栓二3的左端面上下部分别活动设有连接杆一4和连接杆二5,连接杆一4和连接杆二5的左端分别设有固定卡一6和固定卡二7,固定卡一6和固定卡二7均呈锥形,固定卡一6和固定卡二7之间设有弹簧8,该结构可以在膨胀螺栓外部紧固的同时内部再次卡紧,采用双层卡紧结构,使膨胀螺栓安装东西更加紧固,且可以通过反向旋转螺栓二3使固定卡收缩,从而便于拆卸已经安装的东西。该膨胀螺栓,结构简单,采用双层卡紧结构,固定东西比较牢固,膨胀套2采用加强结构,使膨胀套2比较耐用。
