Abstract

The invention discloses a dual-bolt fastening structure which comprises spring shims, gaskets, bolts, movable boxes, fastening plates and a workpiece groove. The bolts are connected in the movable boxes. The spring shims and the gaskets are located between the bolts and the movable boxes. The fastening plates abut against the bottoms of the bolts. The workpiece groove is formed between the fastening plates. By means of the manner, the dual-bolt fastening structure is simple in structure, convenient to install and maintain and good in fastening performance.

Description

technical field [0001] The invention relates to a fastening structure, in particular to a double bolt fastening structure. Background technique [0002] With the continuous development of modern science and technology, the convenience of various parts has become a trend in the development of today's society. For some existing fastening structures, their structures are relatively complicated and large, and the fastening force is low. More generally, because of this, the insufficient fastening force of the structure leads to inaccurate machining dimensions of many workpieces, and even leads to unreliable fastening of workpieces, which may cause mechanical damage or personal injury due to falling. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a double-bolt fastening structure, which not only has a simple structure and is easy to install, but also has strong fastening force. [0004] In order to solve...
