Description

膨胀式螺钉
技术领域
本发明涉及工具配件领域，特别指出一种膨胀式螺钉。
背景技术
常规的螺钉采用敲击的方式，将两个物体进行固定，市面上的膨胀螺钉包括螺钉本体以及包裹在螺钉本体外侧的胀套，通过螺钉本体压入胀套内，使胀套对工件进行紧固，这类膨胀螺钉多为一次性使用的，而且难以拔出，容易造成胀套残留在工件内，给后续的拆卸带来一定的困扰。
发明内容
本发明的目的是提供膨胀式螺钉，改变传统螺钉敲击紧固的方式，通过旋转圆台形旋转体，使得外衬套胀开实现紧固与松懈，可反复使用，提高利用率，节约建材，具有实用性。
实现本发明目的的技术方案如下：
膨胀式螺钉，包括圆台型旋转体，所述圆台型旋转体表面设有连续的螺旋凹槽，还包括外衬套，所述的外衬套为中空结构，两端设有用于通过圆台型旋转体的通孔，还包括外衬套中空结构内设有压力球，所述的压力球通过外衬套内侧的限位板固定，所述的压力球均卡在所述的螺旋凹槽内，所述的外衬套采用铝塑片材料制成。
进一步的，所述的压力球与外衬套内侧还连接有弹性块。为保护外衬套不会被圆台形旋转体强烈胀开,
进一步的，所述的外衬套与圆台型旋转体轴承平行的侧面设有内凹陷。
进一步的，所述的圆台型旋转体其直径较大的一端面设有旋转把手。
采用上述结构后，本发明的有益效果是：改变传统螺钉敲击紧固的方式，通过旋转圆台形旋转体，使得外衬套胀开实现紧固与松懈，可反复使用，提高利用率，节约建材，具有实用性。
附图说明
图1为本发明的结构示意图。
图2为本发明的所述圆台型旋转体的结构示意图。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1所示，膨胀式螺钉，包括圆台型旋转体1，所述圆台型旋转体1表面设有连续的螺旋凹槽2，还包括外衬套3，所述的外衬套3为中空结构，两端设有用于通过圆台型旋转体1的通孔，还包括外衬套中空结构内设有压力球4，所述的压力球4通过外衬套内侧的限位板5固定，所述的压力球4均卡在所述的螺旋凹槽2内，所述的外衬套3采用铝塑片材料制成。
所述的压力球与外衬套内侧还连接有弹性块6。为保护外衬套不会被圆台形旋转体强烈胀开,
所述的外衬套与圆台型旋转体轴承平行的侧面设有内凹陷7，能满足在膨胀螺钉使用过程中，方便膨胀螺钉插入到工件的通孔中，同时在膨胀过程中不会与工件通孔紧密贴合，造成气压差导致难以拔出。
所述的圆台型旋转体其直径较大的一端面设有旋转把手8。方便操作人员对圆台型旋转体进行操作。
本发明并不局限于所述的实施例，本领域的技术人员在不脱离本发明的精神即公开范围内，仍可作一些修正或改变，故本发明的权利保护范围以权利要求书限定的范围为准。
