Detailed ways

The present invention will be further described with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

As shown in Figures 1 to 2, it is an anti-overload self-adjusting safety horizontal bar structure provided by the present invention.

The horizontal bar structure includes a horizontal bar body 1 and fixed head assemblies 2 arranged at both ends of the horizontal bar body 1. The horizontal bar body 1 is a telescopic structure, and the fixed head assemblies 2 on both sides are used to press on the door frame to fix the horizontal bar.
