The invention provides an expansion nut convenient to mount. The expansion bolt is characterized in that a lower nut body, an upper nut body, center screw holes and mounting bars are included; the lower nut body and the upper nut body are of an integrated structure, and the center screw holes are formed in the center in of the lower nut body and the center in the upper nut body; each center screwhole comprises a threaded hole portion and a round hole portion, and the center screw holes penetrate through the upper nut body and the lower nut body; and the mounting bars for facilitating operation in the mounting process are arranged on the outer side walls of the upper nut body and the lower nut body. Compared with the prior art, the expansion nut convenient to mount is reasonable in structure; by means of the mounting bars arranged on the upper nut body and the lower nut body, the mounting bars can cooperate with a mounting tool and are not likely to slide out; and the mounting bars canachieve a positioning function, the expansion nut is not likely to deflect in the mounting process, and therefore the mounting efficiency of an operator is improved.
Description
【Technical field】 [0001] The invention relates to the technical field of fastener production, in particular to an expansion nut that is easy to install. 【Background technique】 [0002] The expansion nut is a very practical and common fastener. In the prior art, the expansion nut is provided with slots or strips on the outer wall of the nut so that it can be installed at the desired position. However, this method is prone to Slippage or inaccurate positioning with the installation tool, resulting in prolonged installation time and low installation efficiency. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide an easy-to-install expansion nut, which aims to solve the technical problems in the prior art that the ordinary expansion nut is easy to slip with the installation tool or the positioning is not accurate, resulting in low installation efficiency. . [0004] In order to ach...
