Description

Technical Field

[0001] The utility model relates to the technical field of threaded rod installation and fixing structures, in particular to a threaded rod installation and fixing structure. Background Art

[0002] Threaded rod is an important mechanical component. It is a cylinder with uniform diameter and spiral grooves on its surface. It usually consists of two parts: a threaded part and a non-threaded part. According to the shape of the thread, threaded rod can be divided into three types: ordinary threaded rod, tower threaded rod and serrated threaded rod. Threaded rod can control the tightening force, so it is widely used in various fields. It can withstand mechanical movements such as connection or rotation between stressed parts and transfer torque. The strength of threaded rod refers to its load-bearing capacity under allowable load, that is, the maximum force it can withstand when subjected to external force. Threaded rod is often used to fasten objects together, especially in vehicles, machines and construction.

[0003] In the actual work on threaded rods, the machinery will generate great vibrations during operation. After the threaded rods are subjected to impact force, they are prone to shear force with the threaded head and break. Moreover, under the influence of long-term vibration, the threaded rods are prone to slowly loosen and fall off, thus affecting the normal work of the user. The installation stability of the threaded rods is poor, the use is inconvenient, and the installation effect is poor. Utility Model Content
