In addition, the inflation process of the annular air bag also provides additional support and stability to the entire barbell structure.

[0022] Improved safety: The introduction of the annular air bag and the buffer assembly is a major innovation of this application. When the barbell accidentally falls, the gas inside the annular air bag will enter the annular cylinder through the air outlet pipe, pushing the piston plate to move and compressing the spring, achieving the buffering effect. At the same time, the design of the rubber pad and the exhaust hole further enhances the buffering effect, effectively reducing the risk of injury to the user or the surrounding environment when the barbell falls.

[0023] Optimized user experience: The grip grooves and anti-slip protrusions designed on the support not only facilitate users to hold and operate the barbell, but also improve the comfort and safety during use. Especially in rehabilitation training, these designs help patients better control the barbell and reduce the risk of accidents. BRIEF DESCRIPTION OF DRAWINGS
