[0002] In recent years, with the continuous development of infrastructure construction such as buildings, bridges, roads and pipelines, the demand for fixed steel pipe rods has continued to increase. However, during use, traditional fixing structures may have problems such as loosening, twisting or falling off, affecting the stability and safety of the project. Therefore, it is necessary to design a self-locking structure for fixing steel pipe rods;

[0003] To this end, the patent with publication number CN219343973U discloses a steel pipe fixing lock buckle with a replaceable internal locking structure. Its technical solution includes: a protective block, an anti-slip ring and a locking ring. The top and bottom of the locking ring are fixedly connected with a buffer ring. A connecting bolt is detachably installed between the locking rings on both sides of the buffer ring. Protective blocks are slidably installed on the top and bottom of the locking ring outside the connecting bolt. Fixed blocks are fixedly installed at both ends of the protective block at the bottom of the buckle. An anti-slip ring is fixedly connected to the inside of the locking ring. An insert block is fixedly installed on the top and bottom of the movable ring. A rubber block is fixedly connected to the inside of the movable ring. A fixing bolt is installed through the movable ring and the insert block. The present application uses a combination of various structures to enable the device to realize the use of the device to lock steel pipes of similar calibers, thereby increasing the scope of application of the device, while increasing the effect of locking the steel pipe, and improving the protective effect of the device itself, thereby extending the service life of the device.

[0004] Although the steel pipe fixing lock mentioned above prolongs the service life of the device, it does not perform secondary fixation when locking, and is prone to loosening. Therefore, it is necessary to design a self-locking structure for fixing the steel pipe rod that can perform secondary fixation. Utility Model Content
