Abstract

The invention discloses a novel automated chair back pressure resistance and fatigue resistance testing device. The device comprises a supporting bracket, a tightening bracket, a tightening mechanism and a control cabinet, wherein the tightening bracket comprises four first vertical columns and a plurality of supporting frames; the tightening mechanism comprises a tightening cylinder, a balancing weight, two tightening supporting rods arranged on one side of the balancing weight, and an upper tightening wheel and a lower tightening wheel arranged between the two tightening supporting rods; a tightening chain is connected with the balancing weight; the tightening chain winds the upper tightening wheel and the lower tightening wheel respectively to be connected with a chair back; the supporting bracket comprises a plurality of second vertical columns, and a top frame and a bottom frame which are arranged among the second vertical columns; a supporting platform for supporting a chair is arranged in the top frame; a PLC is arranged in the control cabinet; an operation panel is arranged at the top of the control cabinet; the PLC is electrically connected with the tightening cylinder through an electromagnetic valve. The device is high in stability in the testing process, is accurate and reliable in testing results, and meanwhile can be applied to the testing of chairs with various models.

Description

technical field [0001] The invention belongs to the field of chair quality detection, in particular to a novel automatic chair back pressure resistance and fatigue test device and a test method thereof. Background technique [0002] During the normal use of the seat, the back of the seat will be subjected to cumulative load and impact force, so a safe and reliable seat must be able to withstand a certain amount of compression and fatigue tests. [0003] However, existing seat manufacturers generally lack special seat back compression test equipment, and usually use temporary test equipment for testing. This kind of temporary test equipment is generally relatively simple, so that the stability and accuracy in the test process The degree is not guaranteed, and the applicable chair models are also limited. Contents of the invention [0004] In order to solve the defects and deficiencies in the above-mentioned prior art, the present invention provides a new type of automatic ...
