Abstract

本实用新型公开了水泥锚固钉，旨在提供一种结构简单、连接可靠、不易松动、制造容易、使用方便的水泥锚固钉。它包括有前端圆锥形的螺杆，螺杆上制有螺纹，其特征是在螺杆尾端连接有圆柱头，在圆柱头上制有供旋转螺杆用的棱柱凸台或凹坑。该实用新型的优点是由于圆柱头明显大于螺杆，连接可靠，当原孔中水泥锚固钉拆去后，孔中不留连接件，孔表面平整，即使需要在原孔位置再利用，可改用更大规格的水泥锚固钉即可。该水泥锚固钉可广泛用作与水泥、砖墙等固定体的连接，具有连接可靠、表面美观，对原孔位置可再利用的优点。

Description

水泥锚固钉 
技术领域
本实用新型涉及一种用于固定在水泥构件上的螺钉，尤其涉及水泥锚固钉。 
背景技术
通常的膨胀螺栓是由大头的螺栓、胀管、平垫圈、弹簧垫和六角螺母组成。使用时，先用冲击电钻(锤)在固定体上钻出相应尺寸的孔，再把螺栓、胀管装入孔中，旋紧螺母，螺栓底下的大头就把胀管涨开，使螺栓、胀管、安装件与固定体之间胀紧成为一体。这种膨胀螺栓的缺点是外露部分不光洁，在拆卸后螺栓和胀管仍留在固定体上，原来用过膨胀螺栓的固定位置不能再重新安装固定件，并有螺栓外露表面。 
发明内容
本实用新型的目的是解决现有产品中存在的缺点，提供一种结构简单、连接可靠、不易松动、制造容易、使用方便的水泥锚固钉。 
为了达到上述要求，本实用新型是这样实现的：它包括有前端圆锥形的螺杆，螺杆上制有螺纹，其特征是在螺杆尾端连接有圆柱头，在圆柱头上制有供旋转螺杆用的棱柱凸台或凹坑。所述的棱柱凸台为六棱柱。所述的凹坑为内六角槽的凹坑或梅花槽的凹坑。在所述圆柱头的底面制有防松齿。在螺杆外表面上制有2～3条三角形的切削槽。 
按照上述方案制造的水泥锚固钉，使用时，先用冲击电钻(锤)在固定体上钻出相应尺寸的孔，再把水泥锚固钉放在孔中，用电钻将水泥锚固钉拧入孔中，利用螺杆上的螺纹使水泥锚固钉与固定体连接。其优点是由于圆柱头明显大于螺杆，连接可靠，当原孔中水泥锚固钉拆去后，孔中不留连接件，孔表面平整，即使需要在原孔位置再利用，可改用更大规格的水泥锚固钉即可。该水 泥锚固钉可广泛用作与水泥、砖墙等固定体的连接，具有连接可靠、表面美观，对原孔位置可再利用的优点。 
附图说明
图1是圆柱头上制有六棱柱凸台的水泥锚固钉主视图； 
图2是圆柱头上制有凹坑的水泥锚固钉主视图； 
图3是六角槽凹坑的俯视图； 
图4是梅花槽凹坑的俯视图； 
图5是图1的仰视图。 
其中：1、螺杆；2、螺纹；3、圆柱头；4、六棱柱凸台；5、内六角槽的凹坑；6、梅花槽的凹坑；7、防松齿；8、切削槽。 
具体实施方式
下面结合附图和实施例对本发明作进一步的说明。 
图1是圆柱头上制有六棱柱凸台的水泥锚固钉主视图。从图中看出，水泥锚固钉它包括有前端圆锥形的螺杆1，螺杆1上制有螺纹2，在螺杆1尾端连接有圆柱头3，在圆柱头3上制有供旋转螺杆用的六棱柱凸台4如图1所示，或内六角槽的凹坑5如图2、图3所示或梅花槽的凹坑6如图4所示。在所述圆柱头3的底面制有防松齿7如图5所示。在螺杆1的外表面上制有2～3条均匀分布的三角形切削槽8。
