Abstract

The invention relates to a bounce test machine and a test method for children's dining chairs. The upper part of the base is successively provided with a height adjustment rod assembly, a power unit, and a travel limit hole is arranged on a fixed bracket between them; position. Test method: Clamp the children's dining chair on the table, put a standard weight into the children's dining chair, and then align the bumper of the dining chair bounce test machine with the bottom of the children's dining chair, that is, its back , adjust the corresponding stroke, set the required number of tests, turn on the power, the bumping piece connected to the power unit reciprocates and hits the bottom of the test piece in the vertical direction, and its weight bounces up and down repeatedly, impacting the seat surface, The stroke of the bumper is limited by the distance between the up-stroke switch and the down-stroke switch, and the relevant data of the fatigue life of the dining chair is obtained on the counter. If the baby dining chair is not damaged within the number of fatigue life required for the set test, it is qualified product.
