AI Technical Summary

Technical Problem

In existing mobile welding equipment, the installation and disassembly of acetylene tanks are not convenient to be carried out quickly, and the bolt fixing method is inefficient.

Method used

The design features a fixed frame, which allows for quick locking and unlocking of the acetylene cylinder through the placement opening of the fixed frame and the elastic element of the locking tongue. Combined with a sliding groove to provide a guiding path, elastic pads and arc plates are used to increase friction and accommodate acetylene cylinders of different sizes.

Benefits of technology

It simplifies the installation and dismantling process of acetylene tanks, improves installation and dismantling efficiency, reduces the labor intensity of operators, increases the stability and versatility of equipment, and extends the service life of acetylene tanks.
