Description

technical field

[0001] The invention relates to a horizontal tensile testing machine, in particular to a movable beam fixture of the horizontal tensile testing machine, and belongs to the technical field of tensile testing machines. Background technique

[0002] The horizontal tensile testing machine is mainly used in the tensile test of cables, optical cables, submarine cables and other materials. Since the stroke of the cylinder rod of the tensile testing machine is limited, according to the styles of different lengths, it is necessary to choose to fix the moving beam fixture in the horizontal tensile testing machine. The corresponding parts on the testing machine have a pair of pins at both ends of the moving beam fixture, and the pins are inserted into the fixing holes on the side wall of the horizontal tensile testing machine to complete the fixing of the moving beam fixture.

[0003] Generally, the pin of the moving beam of the horizontal tensile testing machine is man...
