Description

用于重型机械的防松螺栓
技术领域
本发明属于螺栓，具体设计可用于强震环境或重型机械的螺杆、膨胀杆、防松螺栓。
背景技术
强震环境和重型机械震动严重，螺栓容易松，值得改进。
发明内容
本发明的目的在于针对现有技术的不足提出可用于强震环境或重型机械的螺杆、膨胀杆、防松螺栓。还可用于地震易发地区的一些紧固装置上。
本发明具有技术内容：
1、一种螺杆，其特征在于：由杆身、中心通孔、十字槽、杆头构成；杆身为圆柱状，表面具有螺纹；杆头位于杆身的一端；中心通孔轴向设置在杆身的对称轴上，中心通孔贯穿杆身和杆头；十字槽轴向设置在杆身的对称轴上。
2、一种膨胀杆，其特征在于：由导杆、圆环、十字杆、膨胀头构成；圆环内径大于导杆外径，导杆与圆环之间由十字杆相连，导杆、圆环、十字杆三者共轴；膨胀头连接于导杆末端，膨胀头在圆环方向上与导杆连接位置上具有楔入斜面；十字杆在膨胀头方向的反方向上具有锲入倒角。
3、如技术内容2所述的一种膨胀杆，其特征在于：所述的膨胀头为圆柱形、球形。
4、一种防松螺栓，其特征在于：由如技术内容1所述的螺杆、如技术内容2或3所述的膨胀杆、螺帽构成；膨胀杆的导杆的直径小于等于螺杆中心通孔的直径，膨胀杆的膨胀头的直径大于螺杆中心通孔；膨胀杆的十字杆的厚度小于螺杆的十字槽的宽度；膨胀杆的导杆插入螺杆中心通孔；螺帽与螺杆的杆身配合。
5、如技术内容4所述的一种防松螺栓，其特征在于：在螺帽与膨胀杆之间还具有环状弹簧垫片。
技术内容说明及其有益效果：
本发明的主要原理：随螺帽的拧进膨胀杆一起推进，膨胀头是螺杆尾部膨胀，并保持，使螺帽在震动时无法退出。增加一个弹簧垫片的情况下，拧紧后由于弹簧垫片的弹力使膨胀杆总是受到向内的力，紧贴螺栓连接物的表面，螺帽无法反转松开、还可以起到防盗的作用。
本发明的有益效果：可用于矿山机械或重型机械，不会因震动而松脱。在地震易发地区的一些紧固装置上应用一能取得有益效果。
