Hollow nut and expansion bolt assembly

Abstract

The utility model relates to the technical field of connecting pieces, and discloses a hollow nut and an expansion bolt assembly. The hollow nut comprises a nut body and a conical head which are integrally connected, an inner hole penetrating through the nut body and the conical head is formed in the hollow nut, and threads are arranged on the hole wall of the inner hole. The conical head is provided with a first end and a second end which are oppositely arranged, the first end is connected to the nut body, and the outer diameter of the first end is larger than that of the second end. According to the hollow nut and the expansion bolt assembly, by designing and improving the structure of the hollow nut, the technical problem that an expansion bolt component cannot be repeatedly used in the related technology is solved. 本申请涉及连接件技术领域，公开了一种空心螺母和膨胀螺栓组件。空心螺母包括一体连接的螺母主体和锥形头，空心螺母内设有贯穿螺母主体和锥形头的内孔，内孔的孔壁上设有螺纹；锥形头具有相对设置的第一端和第二端，第一端连接于螺母主体，第一端的外径大于第二端的外径。本申请提供的空心螺母和膨胀螺栓组件，通过设计并改进空心螺母结构，解决了相关技术中膨胀螺栓构件无法重复使用的技术问题。
