Vertical pulling-up test device and test method for chair

Abstract

The invention discloses a vertical pulling-up test device and a vertical pulling-up test method for a chair. The test device comprises a test table, an installing support frame, a clamping component and a lifting mechanism, wherein the test table comprises a base and a support seat fixedly arranged on the base, the support seat bears the chair to be tested, the lifting mechanism is arranged on the installing support frame, and the clamping component is arranged on a movable component of the lifting mechanism. The test method comprises the steps of: fixing the chair to be tested and regulating the position of the clamping component so that the clamping component is clamped in the center part of the front edge of the chair to be tested; repeatedly and vertically exerting the force in the position to be tested of the chair to be tested, and judging that the chair to be tested passes the test if the chair to be tested deforms or fractures within the preset experiment times; and otherwise, judging that the chair to be tested does not pass the test. The test device and the test method have the advantages that the clamping component vertically exerts the force in the position to be tested of the chair to be tested, and the pulling-up resistance intensity of the chair can be inspected through repeated experiments for many times.

Description

technical field [0001] The invention relates to the field of seat performance testing, in particular to a seat vertical pull-up test device and a test method for testing the strength of plastic seats. Background technique [0002] Currently, there is a lack of standardized performance testing methods for plastic seats fixed on steps in sports venues. The European region has proposed to establish a unified parameter standard and corresponding measurement method, but it has not been able to reach a unified consensus. Some countries in other regions have experience in establishing corresponding standards, but it is difficult to form a unified standard, which in turn affects the import and export trade of such products. However, due to the non-uniform test standards and test methods, the research and development of corresponding test equipment is also backward. At present, there is no vertical pull-up test device for this type of seat. Contents of the invention [0003] In v...
