Description

Case and bag pull rod fatigue test equipment Technical Field The utility model relates to the technical field of fatigue testing, in particular to a luggage pull rod fatigue testing device. Background The pull rod part of the suitcase and the pull rod box is a force application part for pulling and lifting the suitcase. In daily use, the load of the filler in the luggage, the environmental factors such as road jolts, step concussion and the like can add extra load to the pull rod. The structural strength of the pull rod determines the safety and durability of the luggage. The application number is CN202120900996.7, discloses a pull rod strength test equipment, including frame, actuating cylinder, piston rod and case and bag, actuating cylinder is fixed to be set up in the frame, the piston rod cooperates with actuating cylinder linkage to extend towards vertical below, this piston rod is kept away from actuating cylinder's end and is equipped with the couple, case and bag pull rod expands and hangs on the couple through the pull rod, actuating cylinder drives case and bag lift and shakes.
