Description

一种双牙螺丝
技术领域
 本实用新型涉及一种双牙螺丝。
背景技术
通常在家具、装饰行业中，经常采用可拆卸结构，在连接上运用一种侧嵌入式铝制旋转锁紧盘和平行顺向与锁紧盘相通的锁紧销构成锁紧***，其中锁紧销另一端螺接有与另一物体垂直连接的塑料螺母，构成直角连接。由于连接需要外部螺丝刀旋转锁螺丝刀旋转锁紧，锁紧盘露出连接板的一侧影响美观，并且连接配合有旋转楔形面，固定锁力臂长，固定螺母短且为硬配合，因此安装时容易产生误差，锁紧后易在振动、扭动等外力作用下松动，应用于家具、装饰上易使安装物变形、松动，导致成品不牢固，影响外观和承载重量；由于安装孔径大且多，并与连接件呈摩擦接触，因此容易造成安装误差。
发明内容
为了解决上述技术问题，本实用新型的目的在于提供一种用于连接家具、管道，解决安装及拆卸时的不方便以及破坏性损坏问题，以达到安装时保障连接的稳固性，同时刻将螺丝隐藏于需连接的物件内，而不影响美观效果的双牙螺丝。
本实用新型的完整技术方案是，一种双牙螺丝，包括一个杆体，所述杆体前端设有木螺纹，所述木螺纹末端连接杆体部分制成外六角；所述杆体后端设有机螺纹，杆体后端机螺纹尾部截面设有一八角星形孔。
所述所述杆体为不锈钢或碳钢杆体。
由上可见，本实用新型与现在技术相比有如下有益效果：
采用上述结构，本实用新型藉由扳手拧动螺丝杆体外六角部使木螺纹钻入连接物以固定，将需连接固定的物件打孔穿过螺丝尾端机螺纹部，用螺母将螺丝隐藏固定于需连接的物件内。可将整个杆体隐藏于物件内，连接稳固，且不影响美观，且拆卸时直接用工具作用于末端的八角星形空，即可将螺丝拧出，拆卸容易。整个连接过程，只有一跟螺丝即可达成，不宜造成连接物件的破裂。
附图说明
此处所说明的附图用来提供对本实用新型的进一步理解，构成本申请的一部分，并不构成对本实用新型的不当限定，在附图中：
图1为本实用新型结构示意图。
具体实施方式
下面将结合附图以及具体实施例来详细说明本实用新型，在此本实用新型的示意性实施例以及说明用来解释本实用新型，但并不作为对本实用新型的限定。
实施例1：
本实施例一种双牙螺丝，包含有一不锈钢或碳钢制杆体1，杆体1前端设有木螺纹2，木螺纹2末端连接杆体部分制成外六角3；杆体1后端设有机螺纹4；杆体1后端机螺纹尾部截面设有一八角星形孔；使用扳手拧动螺丝杆体外六角部使木螺纹钻入连接物以固定，将需连接固定的物件打一与螺丝杆体直径相当的孔孔洞，穿过螺丝尾端机螺纹部，用螺母将螺丝隐藏固定于需连接的物件内，物件孔端外端直径略宽以容纳螺母，以同时使螺母隐藏于物件内；需要拆卸时，使用螺刀工具作用于末端的八角星形空，即可将螺丝旋出。
由上可见，采用上述结构，本实用新型藉由扳手拧动螺丝杆体外六角部使木螺纹钻入连接物以固定，将需连接固定的物件打孔穿过螺丝尾端机螺纹部，用螺母将螺丝隐藏固定于需连接的物件内。可将整个杆体隐藏于物件内，连接稳固，且不影响美观，且拆卸时直接用工具作用于末端的八角星形空，即可将螺丝拧出，拆卸容易。整个连接过程，只有一跟螺丝即可达成，不宜造成连接物件的破裂。
以上对本实用新型实施例所提供的技术方案进行了详细介绍，本文中应用了具体个例对本实用新型实施例的原理以及实施方式进行了阐述，以上实施例的说明只适用于帮助理解本实用新型实施例的原理；同时，对于本领域的一般技术人员，依据本实用新型实施例，在具体实施方式以及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
